 Let's see what happens. Let's start. Thanks for coming. We continue with the set of the WCW. In this case we are going to talk about the lines. The problem is that in context this is the functionality that is most powerful when you are in contract. You can dismantle your WCW or make your WCW be an exception. That's how it is. We have seen the core. It is what you have been doing. Inside the core it is supported by what is called the themes. It is what I have seen in the last episode. It is how it is painted. You can add some finality. These finality can usually come in the theme. Or you can develop your own images. You can exclude them. Or in the theme you have. You can stop. And as you have seen before, it is not the best practice. The functionality must always be within the plugins. To be compatible with the theme. And another option would be to modify the WCW. That's another option. Why do I say this? The most powerful option. Think that there are more than 55,000 plugins available in the repository. In other words, there are more than 55,000 in the repository. There are more than two different plugins available. From the beginning, you will hear a phrase that is very common. That is why there is a plugin. When someone has already thought about it, or a modification of the plugin, you can do it. As I said, we are going to talk about the plugins. How to use them. To extend that functionality we have by default. Because surely you have already started to have that demand of functionalities. What we saw before, you talked about it with zero themes. There is a plugin to help you with zero. With themes from here. With themes that optimize images. There are a series of plugins that help us do that. And practically without technical knowledge. Which is the WCW success. The easy installation. The easy theme installation. Super easy. Presentable quickly. I am closing the bridge. You can find it in this online bridge. I like to define myself as a formative of vocation and profession. But above all, I do not recommend you to see what I really like. I have been working in information technology since 1996. And the last 12 years, in what is open source, with WordPress, and with Electronica. I work as an interpreter in Instagram. I know my business. I am a chief engineer. I am a computer engineer. I am a computer engineer. I am a computer engineer. I do not like to see my children. What are the plugins? To define it easily. They are tools that extend the functionality. With what do I ask for that? Not even. That is the clear concept of what a plugin is. The typologies that we understand simply to solve them. The most important thing is the problem and the problem in the plugins. I need a functionality. I search if there is a repository or someone has developed something. I integrate it into my installation. Normally, if I have the possibility of having a development installation, I use it better than in production installation. Then I solve the ingenious functionality. The most important thing is adaptation. I do not solve the functionality. It changes my appearance. It makes a series of things. I try to find something or try to adapt one of the plugins. The plugins are tools that extend the functionality due to the fact that it brings the installation. They provide features that are characteristic, personalized, designed according to their needs. A plugin can alter the visual part. A plugin can alter the source code to position it better than Google. It is an automated tool that allows us to extend different types of functions. The code that I have could be executed within the function file. It is a file that is mandatory for each of the themes, but it is not the best practice. Why? Because if we put functionalities into this theme, as soon as we change the theme, we will lose the functionalities. When we have installed a plugin, it is something that we also have to start with. There are different types of plugins. Just to let you know, there are the standard plugins, all the ones that we download from the repository or that we install, others that are called dependent plugins, in English dropping, that replace the WordPress function. Normally we do not install them by hand, but a standard plugin that changes the functionality. That is, it improves the WordPress plugin. It is normally linked to the top. This is usually very common in the cache plugins. I am sure you have heard of that already. At some point, the cache plugins usually add a plan. And the most unusual type of plugins are the unprecedented plugins. They are installed manually, important, there is no button through the administrator, and they are always active. In other words, in installations where you think I want to do a functionality that does not deactivate it, imagine in a communication environment something that we want to do, mandatory for operators, a deletion flow, someone has to write, and I deactivate the public button. You can only imagine publishing a series of people. So if I put it in a plugin, the author would go there in a plugin called Imprescindible, one of the most useful in the plugin, and no one can deactivate it. We are going to give you an example. How to install a plugin? There is an infinite of them, more common classes. I saw the WordPress administration panel that you have been seeing today, we are going to remind you that it is the easiest way. And it is quite recent, I did not think that WordPress from the beginning was like that. It was much more manual. It can be. There is a menu that you can find in the repository itself or manually uploading the file. Let's see the examples. In some hosting providers it is also allowed to go via FTP. As you choose the file, you will take it to where it is served, automatically it surprises here someone has posted a file and you can activate it. Whenever you install a plugin by default it is deactivated. And in the last case, which is probably the most annoying, it would be with a command tool that is perhaps the farthest from the point where you are now. We are in the workshop of WordPress from scratch, it would be the WordPress from me or from outside. WordPress has the possibility to interact with a command tool called WordPress 3. In which, in terms of language, we could go by saying WordPress that has a serialization, it is under the user, it installs a plugin, an active plugin, an active plugin. This is usually quite useful for system administrators. When you want to imagine a lot of installations, instead of going one by one, a series of scripts are generated automated to make a series of functions. You do it in one installation and you say, this plugin works. Some plugins and themes can automatically install other plugins. This is simply to say that at some point you are going to install a plugin that is installed again because you have downloaded it from the repository or deployed it, or some theme that by default what you do as soon as it is activated needs a series of plugins. This is another plugin. It is not too technical, I have tried to reduce it, but it is important to understand it. The plugin is installed again, it is not altering our installation at all. I tell you this because it is very common and in our corporate competition that people hear about it. You need to install a plugin from Yoast, a plugin from Yoast for the repository, they will install the one from Yoast and I will do the same. You install from Yoast and it is still the same. It is a mistake because we always talk about installing. It is installing and then activating. What do I put inside? Do you remember the type of plugins that we had? We had the standards, we had the droppings and so on. You can only install the standard ones. The droppings and the mass views do not have a state of installation. Or they are, or they are not. Activated can be any of them. The plugin that is activated is doing something about our installation. Or maybe nothing. There was a plugin to change the source of the area to Times Roman. But maybe on my web there is nothing. Maybe there are plugins that do nothing. Or they have specific features that they have not needed. There is a very famous plugin that is to make contact form. You install it, you activate it but if you do not use that contact form on a page the plugin is installed, spending resources and activate them. Because it is something that is executed within WordPress. Some more and some less. That is why, from now on it is not good to have many plugins. What is the name of the plugin? We are going to ask you. Fernando, what is the name of the plugin recommended? It depends on your web. There are websites that need three plugins and there are electronic conventions that need hundreds of plugins. Because it has a lot of functionalities. Maybe you can do it with three plugins but sometimes it is better to do plugins. Because there are very small ones. Activate, deactivate. Plagings with a lot of functionalities as you have used, it is not called Jetpack. When you start in these libraries you solve a lot of things. But Jetpack is a multi-plagging of a lot of things. It is initially active. A lot of other things that you are going to do. The state of deactivation, that is, the active plugin does not work and before deleting it is active. You could delete it, but it is not recommended. Why is it not recommended? Because when plugins are activated they change things in the installation of libraries. So it has a process of installation and a process of desinstallation. If you directly delete it it is possible that it has left dirty in the installation process. So it is recommended to do desinstallation of the process. Then there are the good practices of the developers of plugins and the bad practices. There are people who do it well, I add a series of characteristics that when I open it I clean it and people who do it cleanly and in the end what you do is that in your database there is a lot of information that you do not need. A question. Is there a plugin that is dedicated to clean your project? No, because each plugin has the ability of the developer to have a good practice for desinstallation and above all in the deleted delete it. It is important in the part of delete because you can know you are wrong. Imagine that in your database it is already a VACA plugin. Activate it, configure it, and in that moment you just let it desactivate it. If the developer of the plugin deleted all the configuration it would have to delete everything. That is why the concept of state is important that you know it. A desactivated plugin is possible that it still consumes resources. It is not doing anything but it has left me characteristics in the database, it has done a series of things that it will not do surely when it is deleted. In addition to the disk space that it occupies. But a standard plugin is the one that is pending to update it. Surely today you have seen some examples of that. WordPress both in the core and in the theme like the plugins has a system of versions. The version that is installed in the plugin is the one that is in that moment. If the developer of the plugin makes an update it will seem to me that it is necessary to update it. We will update it we hope everything works and we will be updated. Many times a plugin offers the possibility that it will come back if it is well developed In this level, things that I would recommend then I will send it to pdf, twitter, etc. A little bit for the blockers related to SEO and if they are more famous for their amount of use or the amount of updates it has because it is the theme of yours. It does not mean that the plugin to SEO is what people understand. It is going to make the content the plugin helps you with a series of directories and some improvements in your installation so that it optimizes your page in 0 content. One of the features a very simple one could be this the famous rgpd having the possibility to implement it to you who have a high complexity or use a plugin that solves a series of things a series of pages add the famous validation maps and then I will write my legal address, that name and give you a series of updates. Part of the analytics we need some kind of analytics because I like to measure who is watching me, how much is watching me from where you are watching me simply this plugin and you can go to Google Analytics and do all the programming part. An example of an administration one of the problems that we can find in our site is the security issue that someone accesses. If you have seen a little bit of the rgpd all the rbs to enter the administration is the name of the domain www.inadmin if I know that you have a WordPress the administration will arrive. Well, this is the plugin simply what you do is change the name and the www.inadmin call it administration call it access to the site at least it hides a little at the marketing level and all those who are working with issues of letters or the likes or whatever this plugin adds a lot of background very simple to use here that I talked about before there is a line that is also called to do more or less automatic this type of things a plugin of optimization called by this installation it is getting bigger and easier to use, which is auto-optimized what you do is a series of technical functionalities that optimize the code optimize the delivery I have heard it before about the optimization of the images that are very useful or that do not have the possibility of your local computer there is a plugin that is in charge of that that is, when you upload the image in your WordPress installation what you do is improve the weight of the image keeping the quality a security plugin that can be worked a plugin for the comments if you have not used your comments that you have used a plugin that allows you to change the installation to your domain in a very simple way it is Duplicate a plugin to add those widgets that you have already seen the click to tweet super simple to direct and a whole in one as I said before that adds a lot of things these would be the plugins let's see in a very simple way that you have already seen the installation of the WordPress it is absolutely empty it is the last stable installation which is the 498 today you have seen modern installations with a 5.0 in beta function some of you have installed the muttenberg plugin we are going to do quickly that same review the installation of plugins very very simple we have a part our plugin installation at this moment there is no activation and we can add a new that what it takes us to a visual of what would be the repository of the plugins really below are those 55.000 and 5.0 plugins and it would be the same to go to this page that is the page of WordPress in Spain WordPress R&D the function of plugins at the same time 55.000 that's it plugin 3 plugin 3 things that you have to appreciate in this type of information as the colleagues said because it has been updated recently the part of active installations gives me very important information very important WordPress if we are in versions if it will work or not the normal thing is that you are always in the last version but if this is very old or the version needs to be and it tells you until which version to test you can say hey this works from version 4 but only tested until version 4.7 maybe it is in version 4.8 which version of PHP that normally all are standard because they will be all compatible to be able to upload here to the repository they had to be compatible that is, a series of information and as I said, the options would be to download from here here I could download and what I download is a file and I could go and add the plugin in a very simple way I would add and it tells me to install I have already installed this is the first step it is even indicating me there to activate if we are going to the plugin list I already have a plugin that I will be able to activate right now it is not doing anything of the plugin yet as soon as I activate it it is already available for this installation in this case I have added a menu to add to each plugin it has a series of functionality because I said that it is very easy or interesting to use the editing of contents so much so with Gupta with the classic editor you already have the right amount of contents a small switch that will help you to define better that content that is, the plugin does not do anything but it helps you that you have better that you make better the description the title or making a series of recommendations I am not sure that everything comes out green because it has a color system but it is something that you can do in a normal way and in this way we make it very simple the other way which is the one that you surely know the one of the repository we are going to add the Cache plugin it would be exactly the same I would look here to offer the search result let's just put the name of the plugin and it takes me to 502 to vaccinate you and the process is exactly the same I always have to install in this case what the installation does is what I have done outside go to the site, download the file and decompress the file as you can see it is much faster but the good thing about the file can be, for example, if you want to keep a previous version yes when you do an initial installation you already have your what would you say, of the plugin and in the first place you put it directly when you are already improving you will have your framework so to speak, whatever it is with all that collected your theme and your plugins and you put it in one go then you can put the content or the display you can complicate everything you want and notice that now we have two active plugins all two and a new thing has appeared it is a plugin in which it is one of the guys who is my lover which is a file which is an advanced plugin this plugin has installed it automatically in the supercache notice that I can't or deactivate it that is to say, it controls the plugin in Cache which can be deactivated or we could use it if I deactivate the plugin the other one is also deactivated that's it, it has been disabled there is a new state which is active help recently, it really is not a state like this it is a kind of recorder this is very good when you have the camera and it says which one is disabled that is, there you have it no it is not disabled if you don't put it in the description it is not disabled you can delete it you can be mistaken the most important thing is that the plugin is independent to be able to delete it you would have to go hand in hand with the installation and delete it that is, it does not have that button to delete it as the Cache plugin has been invented if I go back to the installation of the plugins the dependent is gone automatically that plugin has been created I'll show you with a very simple example the other plugin the one that would be the Masjus which is impressive there is no administration that allows you to upload it as I said before, it is installed manually what you see here is an installation of Warp Press with the directories and so on there is a folder called www.continue that is where all the content is going the themes, images, plugins and so on the plugins would be in the center of this folder, the files that is, a series of things by effect, it had not been activated and it had to be created simply so that you know it yes, you will find it in some way a new folder that is called nfnplugins I'm going to upload a plugin it is not a repository plugin if it is not a plugin, for example that has come to a developer that has made me a measurement for my installation and that, as I said I want it to always be active it is a very important part of this process and if this goes fast when I go to my plugins directory look, there is a new typology that is essential that even the user is scared it has to be better not to delete it and indeed the essential now this is what I have done it is an essential plugin it cannot be activated it cannot be deactivated it cannot be deleted that is, it is always active in our installation unlike the dropping that we saw before that are associated with another plugin if I deactivate the father plugin I have to deactivate it physically in this example that I have done it is a plugin that is not visible I'm just going to show you what this plugin does this plugin is what it does if someone enters the code I do not know if you will see it I have put a comment you are a pot, do not look here imagine that you want to sign the HTML that is, everything that comes out of your installation comes out of it I do not know, for example a client who has not turned off the installation because you leave there an activated and this client is a morose the client if he does not have access to that machine cannot deactivate it or delete it normally it is not used for that it is used for those functions that we want it to be mandatory that it is always fulfilled what it does that is, of course we are in the fascinating world of plugins especially understanding the power it has look what we have talked about vacuum, desire security optimization migration a small portion of code I can do very powerful things but it can also be that if you fall into the web you come out with two plugins because they are going to try to access the same do not install two image optimization plugins because they are going to compete for the same purposes two plugins of desire, for example because they would duplicate the labels yes what do you want to install a plugin that is to put the reviews of Google and ask me for a update and that the functionality of the plugin can be received all in the plugin or you can need a zero service imagine the one we saw before vacuuming and you have it connected with your application I want to have automatic vacuuming but I want to be in this account because there are plugins, for example, that need a license because they require a third service but it is for the change yes a little higher yes, for example no, with the RGPD with the first one it does everything the reason for this is because you can do it very quickly when you see a page and you have to do the contact page then it solves it very easily the user of Wordpress does not know how to develop folders which is a system code there is a plugin that does that and it is very simple because you say what do you want to do in the folder no, contact me, tell me give me a minute, where do you want me to put it in the contact page and you have in 5 minutes an eco page imagine for to do landings it serves for all that kind of a little question we have a group photo that is already all over the world if you want to go out wait for me thank you thank you
