Question

I’m working on a Content Management System, and so far so good.

I’m trying to get the system to work with a maintenance mode system.
This is the code in the script to display the maintenance stuff:

if ($maintenance['value'] == "1") {?>
    <div id="content">
     <div id="errmsg">
      <?php echo $maintenance['notes']; ?>
     </div>
    </div>
<? } else {?>

   <h1><?php echo $title; ?></h1>
   <hr /><br />
   <div id="content">
    <?php echo $contents; 
     if (!$content) { 
      include    ('includes/error/404.php');}?>
   </div>               
<? } ?>

I can verify that the $maintenance[‘value’] variable is working as it should, but this portion o the script isn’t working as it should. The value is currently set to 1, but it still displays the stuff in the else.

Any ideas?

I second Cassy’s proposed notation. My remarks:

I’m not really sure how PHP really handles datatypes but I just checked this site and according to this, your expression should evaluate to true, even if $maintenance['value'] holds the integer 1 (you are comparing it to the string "1").

What is the other value, $maintenance['value'] can hold? “0”? If so, why not just assign TRUE and FALSE to the variable, to be on the save side? Anyway, maybe you can try just to write your expression like this:

<?php if ($maintenance['value']) : ?>

This evaluates to TRUE if $maintenance['value'] holds any of these values:

• true
• 1
• any integer != 0
• “1”
• any string != “0”
