Re: URL variables

Use code tags.

Shouldn't
html Syntax (Toggle Plain Text)
  1. <a href="action.php?id='.$num.'">Text to be displayed</a>
be
html Syntax (Toggle Plain Text)
  1. <a href="action.php?id=<?php echo $num; ?> ">Text to be displayed</a>
?

I ask because you appear to be concatenating $num outside of a PHP block.

Re: URL variables

Always enclose PHP stuff into a PHP block. The code should be:

<a href="action.php?id=<?php echo $num; ?>">Text to be displayed</a>
or in this case printing a variable content:

<a href="action.php?id=<?=$num?>">Text to be displayed</a>
Ops. Scru and me the same response. You can use the last example too.
