Is there any error in console? Did you check that?

define('WP_DEBUG', true);

define('WP_DEBUG_LOG', true);

Add these lines in wp-congig.php. Run your site 2 3 times and check wp-content folder. You can find debug.log file.

Try to check with deactivating plugins one by one and selecting the default theme.

Can you show me the error log or something else so that I can check the actual problem.

I think all files are not there. Try to replace wp-includes, wp-admin folder and all files on root except wp-congig.

See if this helps you.

Ok. I you need to save that image url into options table.
After that you can get the attachment id of that image from the url by doing some custom code like this:

global $wpdb;
 $attachment = $wpdb->get_col($wpdb->prepare("SELECT ID FROM $wpdb->posts WHERE guid='%s';", $image_url )); 

So you can get the image id from this and thus you can check wich image is set as a background.

You can achieve this by using posts_where filter. It’s a simple filter and you can easily use in your code.

@mdrabble
Yes you are right. Anything you want to do in WP, use only WP functions and standards as much as possible.

Are you using media library’s image for background?

<?php previous_post_link( $format, $link, $in_same_term = false, $excluded_terms = '', $taxonomy = 'category' ); ?>

Try this if this could help you.

Thank You. ?? @oabadfol

sorry @elearn2014 not like that. WP has their standers and methods. Its more sufficient than you think. According to me use WP functions only.

Try to use this at least once:

Do this:

foreach( $result as $row ) {
    // do your stuff here
    
}

Is there any specific reason for doing custom sql? Why can’t you use wp function for that?
