Usage

Register ad places

Ad places are registered with drsa_ad_placement_sizes hook. You should pass nested array containing one array element per each ad place. See basic exmaple below.

add_filter( 'drsa_ad_placement_sizes', 'myprefix_register_ad_places' );
function myprefix_register_ad_places() {
    $spots = array(
        array(
            // title whichs shows when adding ads
            'name'      => __( 'Frontpage default' ),

            // unique identified for this placed, used to get ads
            'id'        => 'frontpage-default',

            // add size, uploaded image will be tested against these values
            'width'     => 480,
            'height'    => 480,

            // for having multiple ads in the same place, ads will be shown in the order of least shown to most shown
            'multiple'  => true,
        ),
    );

    return $spots;
}

Get active ad

Getting the active ad is fairly simple, just use get_the_active_ad function and pass the used ad place as a paremeter.

If there is active campaign for that ad place, a random active ad assigned to selected place will be returned. When there is no active campaign, active single ad for place is returned. Default ad and link will be returned if no active campaign or ad are found, if there is no default then return is false.

When there is ad, return is array containing the ad place name, image src, target address and click counter class. Simple usage example is below, but you can modify it according to your needs. Click counter class needs to be in the same element with the target href.

$ad = false;
if ( function_exists( 'get_the_active_ad' ) ) {
    $ad = get_the_active_ad( 'frontpage-default' );
}

if ( $ad ) {
    echo '<a href="' . $ad['target'] . '" target="_blank" class="' . $ad['click_counter_class'] . '"><img src="' . $ad['src'] . '" class="ad ad-place-' . $ad['place'] . '"/></a>';
}

Always check the existance of function.

Adding a shortcode to embed ads into content

You can make your own shortcode to get ads everywhere you want, for example into the content of blog post. Below is simple example of shortcode usage.

add_shortcode( 'ad', 'myprefix_shortcode_show_ad' );
function myprefix_shortcode_show_ad( $atts ) {
    if ( ! function_exists( 'get_the_active_ad' ) ) {
        return; // plugin not active, bail
    }

    if ( empty( $atts ) ) {
        return; // no attributes to shortcode, bail
    }

    // no ad place defined, show error to user and bail if visitor
    if ( ! isset( $atts['place'] ) ) {
        if ( is_user_logged_in() && current_user_can( 'edit_others_posts' ) ) {
            return __( 'No ad place defined', 'textdomain' );
        } else {
            return;
        }
    }

    // get the ad
    $ad = get_the_active_ad( $atts['place'] );

    // no active ad, show error to user and bail if visitor
    if ( ! $ad ) {
        if ( is_user_logged_in() && current_user_can( 'edit_others_posts' ) ) {
            return __( 'No active ads or campaigns', 'textdomain' );
        } else {
            return;
        }
    }

    // return ad html
    return '<a href="' . $ad['target'] . '" target="_blank" class="' . $ad['click_counter_class'] . '"><img src="' . $ad['src'] . '" class="ad ad-place-' . $ad['place'] . '"/></a>';
}

Hooks

Plugin contains a set of hooks for you to use and modify behavior of plugin.

Set default ad and link

If there is no active ads for the place, you can set default image and link for the ad place in question with two different hooks.

Use filter drsa_default_ad/{place-id} to set default ad image src. Use filter drsa_default_ad_target/{place-id} to set default ad address.

Disable UTM tags in ad target url

By default UTM tags are inserted automatically to the ad target address, use filter drsa_use_utm to disable it.

To disable globally, use add_filter( 'drsa_use_utm', '__return_false' ); To disable by ad place, use add_filter( 'drsa_use_utm\{place-id}', '__return_false' ); To disable by single ad, use add_filter( 'drsa_use_utm\ad\{ad-id}', '__return_false' );

Disable or change ad view throttle time

If visitor reloads the page or visits in the same page again within 30 seconds after first visit, the new visit is not counted to ad views. If same ad is shown in multiple pages, each page has it's own throttle prevention. For exmaple if ad is in sidebar, reload within 30 seconds in frontpage does not count new view but visit in another page will.

This is simple prevention to ensure that view count is somewhat accurate.

Change the throttle time with filter drsa_counter_cookie_timeout, return thtrottle time in milliseconds. To disable the feature, return zero.

End ads display at specific amount of views

Set filter drsa_end_ads_by_show_count to true, to switch ad ending from date to view count.

Allow alternative images for ads

Set filter drsa_allow_alternative_image to true, to allow alternative images for ads. This will ad a alternative image field in ad edit screen. Use drsa_alternative_image_desctiption_text filter, to change the description of the field. Default ''.
