[Solved] Server Side Validation question

I am not sure what I am looking for to make this not case sensitive. I have this text field where the user needs to type the word "Yes" in the box. If they type the word "yes" in lower case it will give them the flag. I would like them not worry about case sensitivity. Here is my code

<?php
if(JRequest::getVar('activity_level_agreement') != 'Yes')
return 'Sorry, failed to enter proper word in the Activity Agreement. Please enter the correct word.';
?>

Would it be something like this?

 if(JRequest::getVar('activity_level_agreement') != 'Yes' !='yes')
return 'Sorry, failed to enter proper word in the Activity Agreement. Please enter the correct word.';
?>

Hi silentcid,

Please try

<?php
$ala = JRequest::getVar('activity_level_agreement', '', 'post');
if ( strtolower($ala) != 'yes') {
  return 'Sorry, failed to enter proper word in the Activity Agreement. Please enter the correct word.';
}
?>

Hello Bob,

Thanks for the quick reply and your code works. I guess my assumption on what the code should of look was way off so I guess I'll have to hit up the text books again.

Hi silentcid,

You were pretty close; you can't use JRequest inside an if() condition so I put that on an earlier lie; then strtolower() is the PHP function to force the result into lower case.
