Need help with IF statement Can't Post
Reaching out to the board once again.
Thanks for all the previous help!.

Lets say I have two linked images by each entry.
Maybe some entries only have one link/image but not both and other entries have both links/images. The images are the same for everyone (facebook, twitter icons) so the echo works well here. I may even have some entries that have no linked images.

I want to show the image only if the client puts a link for it in the CMS.

So something like this but need PHP to get it done.
---
If link in CMS, then show image
If no link in CMS then skip and move onto the next image and check for link.
If no links, then don't show images at all.



Makes sense?

Makes great sense.

Here's an approach that might help.

I used it in my foreach loop to display a Facebook image as a link, only if the client entered a Facebook URL in the "facebook" field of the record.

The preg_match part of the code makes sure that an http:// is added to the URL if necessary:

Code
<?php if ($record['facebook']): ?> 
<?php  if  (!preg_match("/^http:\/\//", $record['facebook'])) {$record['facebook'] = "http://" . $record['facebook'];   }  
?> 
 
<a class="alphabet" href="<?php echo $record['facebook'] ?>" target="_blank"> <img src="images/Facebook_icon.gif" alt="Facebook Logo" vspace="5" width="32" height="32" /></a> 
<?php endif ?>

NOTE: You might want to implement the free removeExtraWhitespace plugin that Dave Edis created http://www.interactivetools.com/forum/gforum.cgi?post=84270;search_string=removeExtraWhitespace;#84270
to insure that an errant blank space doesn't trick the if statement into showing the image.

There's a lot more about working with if statements in my CMSB Cookbook http://www.thecmsbcookbook.com

Hope that get's you started.

Works Jerry. Thanks and I have your online book. I should refer to it more often.

Below is my code that I have with that works:

Code
<?php foreach ($featuredRecords as $record): ?> 
..... 
.... 
.... 
... 
 
<?php if ($record['event_venue_facebook_link']): ?><?php  if  (!preg_match("/^http:\/\//", $record['event_venue_facebook_link'])) {$record['event_venue_facebook_link'] = "http://" . $record['event_venue_facebook_link'];   }   
?><a href="<?php echo $record['event_venue_facebook_link'] ?>" target="_blank"><img src="/images/facebook_small22.png" /></a><?php endif ?><?php if ($record['event_venue_twitter_link']): ?><?php  if  (!preg_match("/^http:\/\//", $record['event_venue_twitter_link'])) {$record['event_venue_twitter_link'] = "http://" . $record['event_venue_twitter_link'];   }  ?><a href="<?php echo $record['event_venue_twitter_link'] ?>" target="_blank"><img src="/images/twitter_small22.png" /></a><?php endif ?> 
 
<?php endforeach ?>

Re: [gkornbluth] Need help with IF statement [In reply to] Can't Post
Reaching out for a little more help on this one but with a twist this time.
I love the 'If Link' thing we did earlier.... but what I want to do this now:

IF (checkbox) is Yes
Then show _link

I'm talking about the '_link' that is created from the list page to a detail page.
In my list record editor, I have a field that is a checkbox
Code
<?php echo $record['has_a_page'] ?>
I only want to show the "_link" to the detail page if the checkbox is checked. I was going to wrap the <?php echo $record['title'] ?> with the IF ELSE statement because if the checkbox is not checked I still want to show the unlinked <?php echo $record['title'] ?> but I got stumped on this one.
Help?!

Hi,

Try this:

Code
 
  <?php if ($record['has_a_page']):?> 
    <a href = "<?php echo $record['_link'];?>"><?php echo $record['title'];?></a> 
  <?php else:?> 
    <?php echo $record['title']; ?> 
  <?php endif ?>

Does this seem to be what you're looking for?

Hope this helps
