Mark,
Firstly, definitely post your code. Next, detecting whether the
variable is empty is easy:
<?php
if ( trim ( $_POST['your_html_variable'] ) ) {
// Code here gets executed if there's something in there
} else {
// This code will run if the variable is empty or just leave it
}
I would build a foreach statement, and only echo out the link lines if
the $POST or $GET variables are not empty, like so:
<?php
foreach( $_POST as $value ){
if ( trim ($value) ) {
echo '<a href="' . $value . '">Link text... etc. (you get the
idea)
}//end of the IF statement
}//end of the foreach statement
?>
That's just a basic example, but it should be enough to get you
started. Again, post your code and I can come up with something a
little more complete.
Good luck,
-Nick
