SOLVED: Hide extra field if empty? was created by Johann Scharfetter

Hello!

I was looking for hours to find a solution without success. I hope you can help me.

I have created some extra fields and I'm able do display them in item.php with the following code:

After  I pasted this code



If the extra field is empty it is not dispayed. So far every thing is ok.



But in my case I need something more.



I have some extra code conected to <?php echo $extrafields; ?>



<div class="xyz"><?php echo $extrafields; ?></div>

or

<p><?php echo $extrafields; ?></p>



How can I hide the code like  <div></div>, <p></p>, {slider=xxx}...{/slider} et cetera ... if the extra field is empty?





if  $extraField is empty display  '' ... els   <div class="xyz"> <?php echo $extrafields; ?> </div> .. endif





Thank you!

Hi scharfet,

this is not a ready-to-use solution, but maybe a good approach. You can check whether the variable is set and empty or not by using the PHP functions isset() and empty().

This will check if $extrafields is set and not empty:


	isset()


	empty()


	array_key_exists()


I hope that I have understood correctly what your problem is.



Best regards,

Julian

Thanks for the thread. I had the same need.

My issue is when the extra field is an image. Image fields will display the alt text even when their is no image, which makes the field not emply.

Any suggestions on how to write the php code to not display anything when using an image field.

Thanks! -- Steven

Just updated to K2 2.6.3 and the issue is resolved. All is working correctly now.

Thanks!

Hey folks I worked this out for the new way K2 2.6.2 handles emptyfields so nothing shows if the extrafield in question is empty.

<?php if(isset($this->item->extraFields->EXTRAFIELDALIASHERE->value) === true  && empty($this->item->extraFields->EXTRAFIELDALIASHERE->value) === false): ?>
<span class="itemExtraFieldsLabel"><?php echo $this->item->extraFields->EXTRAFIELDALIASHERE->name; ?>:</span>
<span class="itemExtraFieldsValue"><?php echo $this->item->extraFields->EXTRAFIELDALIASHERE->value; ?></span>
<div class="clr"></div>
<?php endif; ?>

Just swap your extrafield alias with EXTRAFIELDALIASHERE and you're good
