First time poster. PHP idiot.

I need to (re)write code that will display a div if a field is entered but to hide it if it's empty. The field is populated using a custom field in the backend of Wordpress.

I wrote this code many years ago and it used to work but no longer does. My skill level is 0. This is it:

$video = get_post_meta($post->ID, 'video_file_name', true);
if ($video == '')
{ ?>
<div class="hide">
<!-- hide video -->

<?php } else { ?>
<div class="show">

This a javascript block that shows a video player.

<script src="this_code_is_hidden.js"> </script>
<div id="mediaspace">text will be replaced</div> 
<script type="text/javascript">   
'file': 'http://video.xxxxx.com.au/<?php the_field('video_file_name'); ?>',
    'client': "vast",
    'tag': google ad invocation code
 'title': '<?php the_title(); ?>',
        'ga': {
        'idstring': '<?php the_title(); ?>',
        'label': '<?php the_title(); ?>'
'image': '<?php the_field('poster_frame'); ?>', 
"sharing": {
    "link": "http://www.xxxxx.com.au"
'controlbar': 'bottom', 
'stretching': 'fill',     
'width': '100%', 
'aspectratio': '16:9',
'height': '332'
<?php } ?>

I've hidden some bits for security.

The theory is when ('video_file_name') is populated it will show the javascript block which will display a video.

I use CSS classes to either hide or show.

If anyone can shed some light I would be most appreciative. I've spent hours searching and trying but not clever enough to make it work.

I don't know if you can 'echo' a whole code block.

Thank you.

  • Try changing this if ($video == '') to if( empty( $video ) ). May 5 at 15:10
  • In what way is it not working?

  • Hi Tony, I'll give it a shot. May 8 at 1:38
  • Hi Vancoder, it's not hiding the div when the text field is empty. May 8 at 1:40
  • Hi Tony @tony, I've tried your suggestion and unfortunately it hasn't worked. Have I set up my variable incorrectly. <?php $video = get_post_meta($post->id, 'video_file_name', true); if ( empty( $video ) ) { ?> <div style="display:none;"> <!-- hide video --> </div> <?php } ATM moment when the text field 'video_file_name' is entered, it's hiding the div - the opposite I was hoping for!
