Link Field Array within Function

Hi,

I have a field on specific post pages which allows the user to create a new link to forward the user to a completely new URL (this is so it still appears within the filtering of Post Content and has a name, excerpt and thumbnail – but directs the user offsite)

So I found a function which allows that, but although it’s a Link and an Array it won’t pass through the target=”_blank” when clicked.

I feel it’s because I need to update the function to look for if the “Open in New Window” is ticked.

This is inside functions.php

function prefix_custom_link_option( $url, $post ) {
	// Create an array of post types to skip.
	$skip_post_types   = array(
		'attachment',
	);

	// page_link gives the ID rather than the $post object.
	if ( 'integer' === gettype( $post ) ) {
		$post_id = $post;
	} else {
		$post_id = $post->ID;
	}

	// Check if the current post type should be skipped.
	if ( in_array( get_post_type( $post_id ), $skip_post_types, true ) ) {
		return $url;
	}

	// Get the custom_link if one exists.
	$custom_link = get_field( 'new_page_link', $post_id );

	if ( $custom_link ) {
		$url = $custom_link['url'];
		$url_target = $custom_link['target'] ? $custom_link['target'] : '_blank';      
	}

	return $url;
}

/**
 * Add filters for post_link, page_link, and post_type_link to update Custom Link
 */
foreach ( [ 'post', 'page', 'post_type' ] as $post_type ) {
  add_filter( $post_type . '_link', 'prefix_custom_link_option', 10, 2 );
}

Any help would be greatly appreciated.

Thanks

The filter you are using can only be used to filter the actual URL and does not have the ability to alter any of the properties of the <a> element. What function are you calling to get the entire link element?
