Question

I am a beginner in PHP-Codeignitor.So i dont know this question too waste for you guys.

But is there any easy way to validate form data ?

Ex.I have a table and it contain a text field “username”,there is a insert button too,whern user clicked on insert it will add another text field.

So how can i get the value(s) in php ? because user can add any number of fields there.

$username = $_POST(“username”); //what it will retrieve in this case ? array ?

Also how can handle situation like this.

Thank you.

If you set an array in the form, you will get an array in $_POST.

form fields:

<input type='text' name='username[]' />
<input type='text' name='username[]' />

php:

$users_array = $_POST['username'];
