custom_url_contains_condition_acf.php

/**
 * This is the ACF version.
 *
 * Instead of using a hardcoded string to test for, you can add an ACF field to your popups.
 *
 * First, create your custom field group and add a location rule for it to show up in popup post types.
 *
 * https://www.advancedcustomfields.com/resources/creating-a-field-group/
 *
 * Second, edit your popup. Make sure you're showing your new field in the Screen Options. Under Settings > Targeting, 
 * change your Custom PHP Function name to custom_url_contains_condition_acf.
 *
 * Lastly, enter the string value you want to url to contain into your new ACF field.
 *
 * In the example below, the ACF field name for my popups is "test". If I edit my popup, 
 * set the ACF "test" field value to "content", set my targeting custom PHP to "custom_url_contains_condition_acf"
 * my popup will load and launch on pages that have the string "content" in the URL path.
 *
 * Example URL: https://twenty-twentyone.test/content-control-shortcode/
 *

	if ( !str_contains( home_url( $wp->request ), $contains_str ) ) return; // If my ACF value was "content" and the page's URL is "/this-post-has-cool-content", my popup would load and display.

Screen capture of the Targeting condition

Screen captures for the ACF version

1) Creating the ACF field called Test

2) Creating an ACF location rule for the Test field to show on the popup edit page

3) On the popup editor page, make sure the Test field screen option is checked (turned on) so it displays on the popup edit page. Redundant, I know.

4) ACF Test Field with its value set to the word "content" on the popup editor page

5) The popup targeting condition now using the ACF version of the custom PHP function
