strlen question |
|---|
| message from melissa on 23 Jul 2004 |
<?php if(strlen($_POST['item01']) > 0) { ?>
<?php } ?>
(with the help of this forum!!)
the form is separated into 5 sections and if there are no items filled out
in that section, then i need to hide the title too.
I have been playing around with the syntax and am not having any
success.......any suggestions?
here is a sample of what i am trying:
<?php if(strlen($_POST['item01', 'item02', 'item03']) > 0) { ?>
<?php } ?>

<?php if((strlen($_POST['item01']) > 0) || (strlen($_POST['item01']) > 0) ||
(strlen($_POST['item01']) > 0)) { ?>
Title goes here
<?php } ?>
Basically, you use the OR operator || , so if one of the items has a length
greater than 0 the title will be shown

Sorry, should have been
<?php if((strlen($_POST['item01']) > 0) || (strlen($_POST['item02']) > 0) ||
(strlen($_POST['item03']) > 0)) { ?>

Or you could do something like:
?>php
if (strlen($_POST['item01'].$_POST['item02'].$_POST['item03'])>0)){
?>
