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 is necessary to setup 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.

Also, a common set of parameters must 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.

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.

Ad Code Manager currently works with Doubleclick for Publishers by default. However, all logic is abstracted which means that you can configure ACM for any ad provider relatively easy. Check `providers/doubleclick-for-publishers.php` for an idea of how to extend ACM to suit your needs.

[Fork the plugin on Github]( and [follow our development blog](

== Installation ==

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
1. Activate the plugin through the 'Plugins' menu in WordPress
1. 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
1. Implement filters to make the plugin work with your provider
1. Configure your ad codes in the WordPress admin ( Tools -> Ad Code Manager )

== 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.
* 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.

* 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 ";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`.

* 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>';
			case 'rich_media_leaderboard':
				$output_html = '<script> // omitted </script>';
		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.

* 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 whitelist which ad code script URLs can be added in the admin

* 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_whitelisted_script_urls' );
	function my_acm_whiltelisted_script_urls( $whitelisted_urls ) {
		$whitelisted_urls = array( '' );
		return $whitelisted_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.

* 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 whitelist these so users can't execute random PHP functions.

* array $conditionals Default conditionals

Example usage: Register a few custom conditional callbacks

	`add_filter( 'acm_whitelisted_conditionals', 'my_acm_whitelisted_conditionals' );
	function my_acm_whitelisted_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.

* 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;
		// has_category and has_tag use has_term
		// we should pass queried object id for it to produce correct result
		if ( in_array( $cond_func, array( 'has_category', 'has_tag' ) ) ) {
			if ( $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 frontend. The default behavior is that each ad code requires a conditional to be included in the presentation logic.

* 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 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(
				'key'       => 'name',
				'label'     => __( 'Name', 'ad-code-manager' ),
				'editable'  => true,
				'required'  => true,
		return $args;
