TOPIC: PHP if statement with image extra field

PHP if statement with image extra field 2 months, 2 weeks ago #170161

I'm trying to display a <div> only if the image extra field is being used. if it is not being used, do not show the <div>

The code looks like this right now:

 
<?php if(isset($extrafields['3']) === true  && empty($extrafields['3']) === false): ?>
<div class="interview-image-block">
<?php echo $extrafields[3];?>
<div class="interview-caption">
<?php echo $extrafields[7];?>
</div>
</div>
<?php endif; ?>

The problem is the $extrafields variable is never empty it either displays

<img alt="Interviewer Image" src="/"> -- NO IMAGE

or

<img alt="Interviewer Image" src=".../image.png"> -- With An Image

So our PHP statement does not really do anything since the $extrafield variable is never empty.

How can I get this PHP code to work?

Thanks!

David Blane ( User ) OFFLINE Fresh Boarder Posts: 2	Apologies, I am using K2 Version 2.6.5 and Joomla 2.5.9 Thanks for pointing me to the new syntax. That helps me for the most part. Although, we would really like to be able to write the Extra Field ID Number and NOT the alias, if possible. I have not been able to figure it out, what are your thoughts? Thanks
