CodeIgniter Registration Form Part 5

[nalixl]

Why work with if .. else .. statements in check_exists_username? Something like this seems more logical to me:

[code]

function check_exists_username($usernam­e){ $query_str = "blah"; $result = blah; if ($result->num_rows() == 0) return true; return false;

}

[/code]

@nalixl

$result = $this->db->query($query, $username);

return ($result->num_rows() > 0) ? true : false;

Nicely done!

'username_not_exists' - pahaha.

Alasdair I think I love you.

[Verbloten]

@ldexterldesign ok? I love you too?

[mystiknrg]

is there a rule to achieve the behaviour opposite to "match"...for example suppose you dont want a username to be the same as your password (for security reasons), hence you would need an validation error to be thrown if both values equal.

Is there a built in rule for that or would I have to write my own callback?

THanks.

[Verbloten]

@mystiknrg You could create a custom rule or just do the following: In system/language/english (or as appropriate) /form_validation_lang.php add: $lang['not_matches']= "The %s field can not match the %s field."; In system/libraries/form_validati­on.php add: function not_matches($str, $field) { if ( ! isset($_POST[$field])) { return TRUE; } $field = $_POST[$field]; return ($str == $field) ? FALSE : TRUE; }

@Verbloten

somewhere near function matches.

Then in your form rules simply say not_matches[username] for the password field

[mystiknrg]

@Verbloten Oh wow..i didnt know it was that easy to extend the functionality of CI
