show if

Hi Ray

I am trying toshow an element based on whether or not 2 entries in the db have content in them. If either has content then the element should be shown. I have tried the below with && and ||. Its fine if there is content in both entries (or no content in each) but the problem arises if there is content in one entry but not the other. At the moment in that instance it hides the element when I am trying to show it.

<?php if ("".($Slideshow->getColumnVal("SlideshowTitle")  ."" != "") && ($Slideshow->getColumnVal("SlideshowContent")  ."" != "")) { ?><div class="ms-layer ms-caption" style="width: 240px; height: 268px; top:0; right:0; background: #b3a895; color: #fff; text-align:center; padding: 0 20px;">
<h2 style="color:#fff;"><?php echo($Slideshow->getColumnVal("SlideshowTitle")); ?></h2>
<p style="color: #fff; font-style:italic;"><?php echo($Slideshow->getColumnVal("SlideshowContent")); ?></p>
</div><?php } ?>



thanks

Jamie

you can just use:

php:
<?php if ($Slideshow->getColumnVal("SlideshowTitle") || $Slideshow->getColumnVal("SlideshowContent")) { ?>

Thats brilliant, thanks Ray. Could I just ask what the difference is between the 2?

It is just simplified and uses "||" instead of "&&"...

Really it looks like your code would have worked with "||" instead of "&&", but by simplifying it becomes easier to read.

I had actually tried using || as well and it didnt work hence my confusion. Not to worry as the one you gave me is working a treat. Thanks VM
