[SOLVED] A small problem

[zamp0e]

Hello there.

 

Is there any way to check if a $_POST does not exist ? I've been trying this:

 

elseif(is_array($_POST['varldsdel'])=="0" || is_array($_POST['pi'])=="0" || is_array($_POST['kriget'])=="0" || is_array($_POST['vem'])=="0" || is_array($_POST['tal1'])=="0" || is_array($_POST['pythagoras']))

{

echo "Du har inte svarat på alla frågor!";

}

 

I thought this would simply give the response "You have not answered all the questions" (Du har inte svarat på alla frågor), and it does. The problem is that it always goes into that elseif, even if all questions are answered and thereby, all $_POST are defined with a value.

Is there any way to simply check if the $_POST['randomname'] have been defined?

 

Sorry if it was hard to understand, had some problems with expressing the problem in words

 

Thanks in advance.

if(!isset($_POST['some_field']))
{
   /* code */
}

 

Or,

 

if(empty($_POST['some_field']))
{
   /* code */
}

Your problem is that is_array() merely checks to see if the value is an array, not whether or not it exists at all.
