Manage your ad codes through the WordPress admin in a safe and easy way.

Description

Ad Code Manager gives non-developers an interface in the WordPress admin for configuring your complex set of ad codes.

Some code-level configuration may be necessary to set up Ad Code Manager. Ad tags must be added (via do_action()) to your theme's template files where you'd like ads to appear. Alternatively, you can incorporate ad tags into your website with our widget and our shortcode. Check out the configuration guide below for the full details.

A common set of parameters must also be defined for your ad provider. This includes the tag IDs used by your template, the default URL for your ad provider, and the default HTML surrounding that URL. Ad Code Manager comes with support for Google Doubleclick For Publishers (and Async), and Google AdSense. All the logic is abstracted, however, so configuring a different provider is relatively easy. Check providers/doubleclick-for-publishers.php for an idea of how to extend ACM to suit your needs.

Once this configuration is in place, the Ad Code Manager admin interface will allow you to add new ad codes, modify the parameters for your script URL, and define conditionals to determine when the ad code appears. Conditionals are core WordPress functions like is_page(), is_category(), or your own custom functions that evaluate certain expression and then return true or false.

Fork the plugin on Github and follow our development blog.

Installation

The plugin requires PHP 7.1 or later. It is also test on WordPress 5.5 and later, though it may run on older versions.

Since the plugin is in its early stages, there are a couple additional configuration steps:

1. Upload ad-code-manager to the /wp-content/plugins/ directory.
2. Activate the plugin through the 'Plugins' menu in WordPress.
3. Incorporate ad tags in your theme template with do_action( 'acm_tag', 'slot' ). Also you can use [acm-tag id="slot"] shortcode or ACM Widget.
4. Implement filters to make the plugin work with your provider.
5. Configure your ad codes in the WordPress admin (Tools -> Ad Code Manager).

Configure Ad Code Manager to manage the advertisements on your site

Ad Code Manager is a VIP-sponsored plugin designed to make it easier to manage the ad codes used to display advertisements on your site. There's a little bit of work you'll need to do up front, however, in order to integrate Ad Code Manager with your theme.

The high-level idea behind Ad Code Manager is that it gives non-developers an admin interface to manage your ad codes. It then permits users to (optionally) target specific ad codes using conditionals like is_home() and is_single(). Ad codes are associated with positions in the theme through the use of ad tags.

Currently, Ad Code Manager easily integrates with Google Doubleclick For Publishers Async and Google AdSense. Other ad providers are supported with additional configuration.

Google AdSense and DoubleClick For Publishers Async

Let's use AdSense as our first example. You'll want to incorporate some of the default ad tags into your theme by use of do_action(). Here's an example you might put in your header.php file:

do_action( 'acm_tag', '728x90_leaderboard' );

Once you've done so, you can select the "Google AdSense" provider in the admin. Ad codes can be registered against ad tags (positions) by choosing the ad tag from the drop down, entering the tag ID and publisher ID, and hitting "Add New Ad Code".

And like that, your 728x90 leaderboard will appear on your site.

The Google AdSense configuration comes with many of Google's suggested sizes. Additional ad tags can be registered by the way of filtering:

add_filter( 'acm_ad_tag_ids', 'acmx_filter_ad_tag_ids' );
function acmx_filter_ad_tag_ids( $ids ) {
	$ids[] = array(
		'enable_ui_mapping' => true,
		'tag'               => '100x100_smallsquare',
		'url_vars'          => array(
			'tag'    => '100x100_smallsquare',
			'height' => '100',
			'width'  => '100',
		),
	);

	return $ids;
}

Keep in mind that you'll still need to incorporate a do_action( 'acm_tag', '100x100_smallsquare' ); in your theme in order to display the ad tag.

If you choose Google DFP Async as your provider, you'll likely need to register additional ad tags, as we only package two default ad tags.

Custom Ad Provider Implementations

As mentioned previously, other ad code providers are supported with additional configuration. Here's an example of the different filters you would use to configure the older version of Google Doubleclick For Publishers:

/**
 * Define the default URL to be used when rendering ad codes
 */
add_filter( 'acm_default_url', 'acmx_filter_default_url' ) ;
function acmx_filter_default_url( $url ) {
	if ( 0 === strlen( $url )  ) {
		return "http://ad.doubleclick.net/adj/%site_name%/%zone1%;s1=%zone1%;s2=;pid=%permalink%;fold=%fold%;kw=;test=%test%;ltv=ad;pos=%pos%;dcopt=%dcopt%;tile=%tile%;sz=%sz%;";
	}
}

/**
 * Whitelist the DFP URL to be used in ad tags. The whitelist
 * helps prevent execution of arbitrary scripts
 */
add_filter( 'acm_whitelisted_script_urls', 'acmx_filter_whitelisted_script_urls');
function acmx_filter_whitelisted_script_urls( $whitelisted_urls ) {
	$whitelisted_urls = array( 'ad.doubleclick.net' );
	return $whitelisted_urls;
}

/**
 * Define the different ad tags (locations) you'd like to use in your theme
 */
add_filter( 'acm_ad_tag_ids', 'acmx_ad_tags_ids' );
function acmx_ad_tags_ids( $ad_tag_ids ) {
	return array(
		array(
			'tag'      => '728x90-atf',
			'url_vars' => array(
				'sz'     => '728x90',
				'fold'   => 'atf',

			'url_vars' => array(
				'sz'     => '160x600',
				'fold'   => 'atf',
				'width'  => '160',
				'height' => '600',
			),
		),
		array(
			'tag'      => '1x1',
			'url_vars' => array(
				'sz'   => '1x1',
				'fold' => 'int',
				'pos'  => 'top',
			),
		)
	);
}

add_filter( 'acm_output_html','acmx_filter_output_html', 5, 2 );
/**

Configuration Filters

There are some filters which allow you to easily customize the output of the plugin. You should place these filters in your theme's functions.php file or in another appropriate place.

Check out this gist to see all of the filters in action.

acm_ad_tag_ids

Ad tag ids are used as a parameter when adding tags to your theme (e.g. do_action( 'acm_tag', 'my_top_leaderboard' )). The url_vars defined as part of each tag here will also be used to replace tokens in your default URL.

Arguments:

• array $tag_ids array of default tag ids

Example usage: Add a new ad tag called 'my_top_leaderboard'

add_filter( 'acm_ad_tag_ids', 'my_acm_ad_tag_ids' );
function my_acm_ad_tag_ids( $tag_ids ) {
	$tag_ids[] = array(
		'tag'      => 'my_top_leaderboard', // tag_id
		'url_vars' => array(
			'sz'              => '728x90', // %sz% token
			'fold'            => 'atf', // %fold% token
			'my_custom_token' => 'something' // %my_custom_token% will be replaced with 'something'
		),
	);
	return $tag_ids;
}

acm_default_url

Set the default tokenized URL used when displaying your ad tags. This filter is required.

Arguments:

• string $url The tokenized url of Ad Code

Example usage: Set your default ad code URL

add_filter( 'acm_default_url', 'my_acm_default_url' );
function my_acm_default_url( $url ) {
	if ( 0 === strlen( $url ) ) {
		return "http://ad.doubleclick.net/adj/%site_name%/%zone1%;s1=%zone1%;s2=;pid=%permalink%;fold=%fold%;kw=;test=%test%;ltv=ad;pos=%pos%;dcopt=%dcopt%;tile=%tile%;sz=%sz%;";
	}
}

acm_output_html

The HTML outputted by the do_action( 'acm_tag', 'ad_tag_id' ); call in your theme. Support multiple ad formats ( e.g. JavaScript ad tags, or simple HTML tags ) by adjusting the HTML rendered for a given ad tag.

The %url% token used in this HTML will be filled in with the URL defined with acm_default_url.

Arguments:

• string $output_html The original output HTML
• string $tag_id Ad tag currently being accessed

Example usage:

add_filter( 'acm_output_html', 'my_acm_output_html', 10, 2 );
function my_acm_output_html( $output_html, $tag_id ) {
	switch ( $tag_id ) {
		case 'my_leaderboard':
			$output_html = '<a href="%url%"><img src="%image_url%" /></a>';
			break;
		case 'rich_media_leaderboard':
			$output_html = '<script> // omitted </script>';
			break;
		default:
			break;
	}
	return $output_html;
}

acm_register_provider_slug

Ad Code Manager has a built-in list of providers that it gathers by scanning the 'providers' directory used by the plugin. Additional providers can be added by placing the appropriate files in that directory, or by using the acm_register_provider_slug filter to register those that may be included as part of your theme or another plugin.

When using this plugin, you are defining the provider slug as part of the existing object as well as an array of classes associated with that provider slug.

Arguments:

• object $providers An object containing the current registered providers.

Example usage:

add_filter( 'acm_register_provider_slug', 'my_acm_register_provider_slug' );
function my_acm_register_provider_slug( $providers ) {
	$providers->new_provider_slug = array(
		'provider' => 'My_New_Ad_Company_ACM_Provider',
		'table'    => 'My_New_Ad_Company_ACM_WP_List_Table'
	);

	return $providers;
}

acm_whitelisted_script_urls

A security filter to define a safelist for which ad code script URLs can be added in the admin.

Arguments:

• array $whitelisted_urls Existing whitelisted ad code URLs

Example usage: Allow Doubleclick for Publishers ad codes to be used

add_filter( 'acm_whitelisted_script_urls', 'my_acm_safelisted_script_urls' );
function my_acm_safelisted_script_urls( $safelisted_urls ) {
	$safelisted_urls = array( 'ad.doubleclick.net' );
	return $safelisted_urls;
}

acm_output_tokens

Output tokens can be registered depending on the needs of your setup. Tokens defined here will be replaced in the ad tag's tokenized URL in addition to the tokens already registered with your tag id.

Arguments:

• array $output_tokens Any existing output tokens
• string $tag_id Unique tag id
• array $code_to_display Ad Code that matched conditionals

Example usage: Test to determine whether you're in test or production by passing ?test=on query argument

add_filter( 'acm_output_tokens', 'my_acm_output_tokens', 10, 3 );
function my_acm_output_tokens( $output_tokens, $tag_id, $code_to_display ) {
	$output_tokens['%test%'] = isset( $_GET['test'] ) && $_GET['test'] == 'on' ? 'on' : '';
	return $output_tokens;
}

acm_whitelisted_conditionals

Extend the list of usable conditional functions with your own awesome ones. We safelist these so users can't execute random PHP functions.

Arguments:

• array $conditionals Default conditionals

Example usage: Register a few custom conditional callbacks

add_filter( 'acm_whitelisted_conditionals', 'my_acm_safelisted_conditionals' );
function my_acm_safelisted_conditionals( $conditionals ) {
	$conditionals[] = 'my_is_post_type';
	$conditionals[] = 'is_post_type_archive';
	$conditionals[] = 'my_page_is_child_of';

	return $conditionals;
}

acm_conditional_args

For certain conditionals (has_tag(), has_category()), you might need to pass additional arguments.

Arguments:

• array $cond_args Existing conditional arguments
• string $cond_func Conditional function (is_category(), is_page(), etc.)

Example usage: has_category() and has_tag() use has_term(), which requires the object ID to function properly.

add_filter( 'acm_conditional_args', 'my_acm_conditional_args', 10, 2 );
function my_acm_conditional_args( $cond_args, $cond_func ) {
	global $wp_query;

	// The `has_category()` and `has_tag()` functions call the `has_term()` function.
	// We should pass queried object id for it to produce correct result.
	if ( in_array( $cond_func, array( 'has_category', 'has_tag' ) ) && $wp_query->is_single == true ) {
		$cond_args[] = $wp_query->queried_object->ID;
	}

	// my_page_is_child_of is our custom WP conditional tag and we have to pass queried object ID to it.
	if ( in_array( $cond_func, array( 'my_page_is_child_of' ) ) && $wp_query->is_page ) {
		$cond_args[] = $cond_args[] = $wp_query->queried_object->ID;
	}

	return $cond_args;
}

acm_display_ad_codes_without_conditionals

Change the behavior of Ad Code Manager so that ad codes without conditionals display on the front end. The default behavior is that each ad code requires a conditional to be included in the presentation logic.

Arguments:

• bool $behavior Whether or not to display the ad codes that don't have conditionals

Example usage:

add_filter( 'acm_display_ad_codes_without_conditionals', '__return_true' );

acm_provider_slug

By default, we use our bundled doubleclick_for_publishers config (check it in /providers/doubleclick-for-publishers.php). If you want to add your own flavor of DFP or even implement configuration for some another ad network, you'd have to apply a filter to correct the slug.

Example usage:

add_filter(
	'acm_provider_slug',
	function() {
		return 'my-ad-network-slug';
	}
);

acm_logical_operator

By default, logical operator is set to "OR", that is, ad code will be displayed if at least one conditional returns true. You can change it to "AND", so that ad code will be displayed only if ALL of the conditionals match.

Example usage:

add_filter(
	'acm_logical_operator',
	function() {
		return 'AND';
	}
);

acm_manage_ads_cap

By default, user has to have manage_options cap. This filter comes in handy, if you want to relax the requirements.

Example usage:

add_filter(
	'acm_manage_ads_cap',
	function( $cap ) {
		return 'edit_others_posts';
	}
);

acm_allowed_get_posts_args

This filter is only for edge cases. Most likely you won't have to touch it. Allows to include additional query args for Ad_Code_Manager->get_ad_codes() method.

Example usage:

add_filter(
	'acm_allowed_get_posts_args',
	function( $args_array ) {
		return array( 'offset', 'exclude' );
	}
);

acm_ad_code_count

By default, the total number of ad codes to get is 50, which is reasonable for any small to mid-sized site. However, in some certain cases you would want to increase the limit. This will affect Ad_Code_Manager->get_ad_codes() numberposts query argument.

Example usage:

add_filter(
	'acm_ad_code_count',
	function( $total ) {
		return 100;
	}
);

acm_list_table_columns

This filter can alter table columns that are displayed in ACM UI.

Example usage:

add_filter( 'acm_list_table_columns', 'my_acm_list_table_columns' );
function my_acm_list_table_columns( $columns ) {
	$columns = array(
		'id'           => __( 'ID', 'ad-code-manager' ),
		'name'         => __( 'Name', 'ad-code-manager' ),
		'priority'     => __( 'Priority', 'ad-code-manager' ),
		'conditionals' => __( 'Conditionals', 'ad-code-manager' ),
	);

	return $columns;
}

acm_ad_code_args

This filter comes in pair with previous one, it should return array of ad network specific parameters. E.g. in acm_list_table_columns example we have 'id', 'name', 'priority', 'conditionals'. All of them except 'name' are generic for Ad Code Manager. Hence, acm_provider_columns should return only "name".

"editable" and "required" indicate whether this field should be editable and required.

Example usage:

add_filter( 'acm_ad_code_args', 'my_acm_ad_code_args' );
function my_acm_ad_code_args( $args ) {
	$args = array(
		array(
			'key'      => 'name',
			'label'    => __( 'Name', 'ad-code-manager' ),
			'editable' => true,
			'required' => true,
		),
	);

	return $args;
}
