Having trouble with If (isset(..

Post by AdrenalineSeed »

I want to make sure there is data in my array before using it. So that I do not get this error:Undefined variable: signedup in C:\wamp\www\Tournaments\tinfo.htm.php on line 33

Here is what I tried, which is odd because I am using the if statement twice.. but I couldn't see any other way to do it. Anyways I get syntax error and I just don't think I am going about this right.

Code: Select all

  <?php  if (isset($signedup))
  {  foreach ($signedup as $splayer):  }?>      
<p>  
       Player: <?php echo htmlspecialchars($splayer['name'], ENT_QUOTES, 'UTF-8'); ?>.<?php echo htmlspecialchars($splayer['ccode'], ENT_QUOTES, 'UTF-8'); ?> 
     </p>     
       <?php  if (isset($signedup))
  {   endforeach;   }   ?>

Invalid:

Code: Select all

if (isset($signedup)) {
    foreach ($signedup as $splayer):
}
if (isset($signedup)) {
    endforeach;
}
Valid:

Code: Select all

if (isset($signedup)) {
    foreach ($signedup as $splayer):
    endforeach;
}
Valid:

Code: Select all

if (isset($signedup)) :
    foreach ($signedup as $splayer):
    endforeach;
endif;

But I have HTML code in there? How could I endforeach before I get my HTML code in?

This seems to work but now I am echoing every bit of HTML, if the HTML gets really big and complicated, thats going to be messy.

Code: Select all

  <?php
  if (isset($signedup))  
  {
  foreach ($signedup as $splayer):
   echo htmlspecialchars($splayer['name'], ENT_QUOTES, 'UTF-8'); 
   echo ".";
   echo htmlspecialchars($splayer['ccode'], ENT_QUOTES, 'UTF-8');
   echo "<p></p>";
    endforeach;  
}
    
    ?>

Don't echo it, then. Use the same syntax you had before.

The only change I made was in the structure of the if statement. I stripped out the other code because it was irrelevant to the problem.

Oh so I can put a ?> in the middle of an if statement so that I can switch to HTML?

OOOH yea thats what I am doing int he for statement. LOL so strange.... I expect that ?> means stop similar to </script>
