Undefined variable: new_content

I tried your suggestion and deactivated and deleted the plugin. I reinstalled the plugin via the Plugins->Add New, and the problem continues to exist.

I should point out that I’m using custom single-aol_ad.php and archive-aol_ad.php templates.

Changing this:

//Show this content if you are viewing aol_ad post type using single.php (not with single-aold_ad.php)
            if(is_singular() and 'single-aol_ad.php' != wp_basename($template)):
                $new_content = '<div class="aol-single-ad">'.$content.$title_features.$features.$title_form.$form.'</div>';
            endif;
            return apply_filters( 'aol_content', $content, $features, $form );

To This:

//Show this content if you are viewing aol_ad post type using single.php (not with single-aold_ad.php)
            if(is_singular() and 'single-aol_ad.php' != wp_basename($template)):
                $new_content = '<div class="aol-single-ad">'.$content.$title_features.$features.$title_form.$form.'</div>';
				return apply_filters( 'aol_content', $new_content, $content, $features, $form );
            endif;
            return apply_filters( 'aol_content', $content, $features, $form );

At the bottom of class-applyonline-public.php fixed my issue as $new_content is undefined for me due to the wp_basename($template) condition.

I am already using echo aol_features() and echo aol_form() in my single-aol_ad.php, that’s not the problem. I already read the documentation 🙂

The code I posted previously is an issue with the if statement in your plugin code, not my single-aol_ad.php.

If you inspect the code at line 287 in apply-online/public/class-applyonline-public.php you’ll see the if statement above this line is where $new_content is defined, only if the template is not single-aol_ad.php.

Then the apply_filter call outside the if enclosure is attempting to use the variable while the conditions were not met, therefore it is undefined when a single-aol_ad.php template is used.

All you need to do is replace the code at the bottom of apply-online/public/class-applyonline-public.php with the fix I provided above. If you look at line 287 and the if statement above the line, you’ll see what I mean.

Thanks.
