Display default value if field is left empty Can't Post
Hello,

I have a WYSIWYG field for users to describe their listing, however it is not a required field and very often it is left blank.

Is there a way I can display a default value on the front-end website if the user does not type anything?

For example, if the the user doesn't type in a description then I can display at the front-end:

"For further details about this product please contact the advertiser...".

Thank you,
Greg

Are you looking to do this on a listing page, or a detail page?

here is the basic php you will need...

<?php
if(!$field_name) {
echo "<p>Enter default stuff here... </p>";
}
else echo $field_name;
?>

$field_name will need to be updated based on your cms setup. and it will be a little different if it's a listing page versus a detail page.

Hi,

Thanks for the reply. I'd like to do this on a detail page.

How does the code change?

Thanks again,
Greg

Hi,

Do you know why this code isn't working?

Code
if(!$listingsRecord['list_price']) {  
echo "<p>No price specified</p>";  
}  
else 
echo "<? php $listingsRecord['currency']?> <? php $listingsRecord['list_price'] ?>"; 
?> 
 
Thank for you help! 
 
Greg

Hi Greg,

You're not going to need the <?php tags inside your string, since you're already in a PHP block,

try this:

Code
<?php 
  if(!$listingsRecord['list_price']) {   
    echo "<p>No price specified</p>";   
  }   
  else { 
    echo $listingsRecord['currency'].$listingsRecord['list_price']; 
  } 
?>

Hope this helps

Hi Jason,

Thanks for the help. It was the concatenation symbol I needed to know about!

Regards,
Greg
