i keep getting Notice: Undefined index: quantity- in C:\xampp\htdocs\CART\cart.php on line 9

my code around line 9 is: if($_POST['quantity-'.$key] == 0){ unset($_SESSION['cart'][$key])­; } else { $_SESSION['cart'][$key]['quant­ity'] = $value; }

any ideas? its really bugging me. everything still works fine, just get a notice up. thanks!

@sandeepshah89 to get rid of the Undefined Index you can use the function isset() within the if() statement. Eg. if(isset($_POST['...'])) blah blah.

Alternatively, there is nothing wrong with just hiding Notice errors, so in your php.ini file, you can edit the error_reporting section to say E_ALL ~ E_NOTICE

error Notice: Undefined variable: _SESSION in C: \ xampp \ htdocs \ a\ cart.php on line 31

Warning: Invalid argument Supplied for foreach () in C: \ xampp \ htdocs \ a\ cart.php on line 31

Why?

[TheTutSpace]

@Kyrakuum Email me your code and I will see what i can do, but to my it looks like you may have not started the session (use session_start() at the top of the page)

Thanks Tiger :)

seemed pointless being in the group, Where no views were obtained :)

@sandeepshah89 You can get rid of the :

$key = explode("submit",$key);

$key = end($key);

and replace it with:

if($key == "submit") { unset($_SESSION['cart'][$key])­;

}

change the next if to an else if

hello.. my problem is when i click add cart its nothing happen it is not adding to my cart.? answer plss.?

[sandeepshah89]

@TheTutSpace did it!

put if(isset($_POST['quantity-'.$k­ey])){ just outside the if statement if($_POST['quantity-'.$key] == 0){. error message gone, tested the website and all is functional.

just wanted to thank you for this tutorial, gonna add new features and stuff, but it was a great learning curve. thanks

@TheTutSpace is true! I don't use session_start() sorry! thanks for answer
