Question

This is very basic, I know – but I simply can’t figure out why this short section of PHP code isn’t working for me? I’m trying to get a IF statement happening in my function, and then execute the function somewhere on my document so it returns “../”.

<?php $confirm = "yes"; ?>  

<?php
   function clientarea() {
      if (isset($confirm)) {
         if ($confirm == "yes") {
             echo "../";
         }
      }
   }
?>

<img src="<?php clientarea(); ?>images/logo.png" alt="Logo" />

Any ideas why this code doesn’t work for me?

Answer 1

This should work better:

<?php $confirm = "yes"; ?>  

<?php
   function clientarea($confirm) {
      if (isset($confirm)) {
         if ($confirm == "yes") {
             echo "../";
         }
      }
   }
?>

<img src="<?php clientarea($confirm); ?>images/logo.png" alt="Logo" />

You can better use booleans instead of “yes” or “no”…

I modified your code:

<?php $confirm = true; ?>  

<?php
   function clientarea($confirm) {
      if ($confirm) {
             echo "../";
      }
   }
?>

<img src="<?php clientarea($confirm); ?>images/logo.png" alt="Logo" />
