<\/a>Introduction<\/h3>\n

We recommend using the Code Snippets plugin<\/a> to add custom PHP code.
\nCSS can be added to GD > Design > Scripts<\/p>\n

<\/a>Add the package ID\u00a0to the body attribute<\/h3>\n
    \n
  1. If you want to change the looks of the detail page depending on the price package, you\u00a0can do that by adding the ID to the code\u00a0of the detail page:
    \n\"\"<\/li>\n
  2. To do this, add this code to your child theme’s functions.php file:\n

    [php]
    \n\/\/ add the package id to the body
    \nadd_filter( ‘body_class’, ‘my_add_package_class’,10,1 );
    \nfunction my_add_package_class($class){
    \n global $post;
    \n if (geodir_is_page(‘detail’) && isset($post->package_id)) {
    \n $class[] = "gd-package-id-".$post->package_id;
    \n }
    \n return $class;
    \n}
    \n[\/php]<\/p>\n<\/li>\n

  3. You can now target elements of the detail page using the package ID class, for example\n

    [css]
    \n.gd-package-id-1 .geodir-tags {display: none}
    \n[\/css]<\/p>\n

    would hide tags for price packages with ID 1.<\/li>\n<\/ol>\n

    <\/a>Adding CPT-specific content on top of the Add Listing page<\/h3>\n
      \n
    1. If you want to add any special content to your Add Listing page, you can just add that in the content section using the normal way of editing your WP page “Add Listing”.<\/li>\n
    2. If you want to add content specific to a CPT you can use this code, adjust as required:\n

      [php]
      \nfunction geodir_add_place_before_main_content_custom() {
      \n\tif (isset($_GET[‘listing_type’]) && $_GET[‘listing_type’] == ‘gd_place’) {
      \n\t\t?><\/p>\n

      <div>bla bla<\/div><\/p>\n

      \t\t<?php
      \n\t}
      \n}
      \nadd_action(‘geodir_add_listing_before_main_content’, ‘geodir_add_place_before_main_content_custom’);
      \n[\/php]<\/p>\n<\/li>\n<\/ol>\n

      <\/a>Making the listing description optional<\/h3>\n
        \n
      1. The listing description field on the Add Listing<\/strong><\/em> page is a required field by default.<\/li>\n
      2. You can make the description field optional by adding some JS and CSS code.<\/li>\n
      3. Add the following code to GD > Design > Scripts <\/strong><\/em>tab > Footer script code<\/strong><\/em>:\n

        [javascript]
        \n<img src="data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" data-wp-preserve="%3Cscript%20type%3D%22text%2Fjavascript%22%3E%0AjQuery(%20document%20).ready(function()%20%7B%0A%20%20%20%20jQuery(%22%23geodir_post_desc_row%22).removeClass(%22required_field%22)%3B%0A%7D)%3B%0A%3C%2Fscript%3E" data-mce-resize="false" data-mce-placeholder="1" class="mce-object" width="20" height="20" alt="&lt;script&gt;" title="&lt;script&gt;" \/>
        \n[\/javascript]<\/p>\n<\/li>\n

      4. Also add the following CSS code:\n

        [css]
        \n#geodir_post_desc_row label span,
        \n#geodir_post_desc_row .geodir_message_error {
        \n display:none !important;
        \n}
        \n[\/css]<\/p>\n<\/li>\n<\/ol>\n

        <\/a>Sorting on Listings pages: Featured first, then alphabetic<\/h3>\n
          \n
        1. The sorting options for listings<\/a> can only set one default sorting option.<\/li>\n
        2. The following code will order alphabetically even if the default order is set to show featured listings first:\n

          [php]
          \nadd_filter(‘geodir_posts_order_by_sort’,’_my_custom_order_by’,10,3);
          \nfunction _my_custom_order_by($orderby, $sort_by, $table){
          \n\tglobal $wpdb;<\/p>\n

          \tif($sort_by==’is_featured_asc’){
          \n\t\t$orderby .= " $wpdb->posts.post_title ASC, ";
          \n\t}
          \n\treturn $orderby;
          \n}
          \n[\/php]<\/p>\n<\/li>\n<\/ol>\n

          <\/a>Detail page – hide ‘No Reviews’ text if there are no reviews<\/h3>\n
            \n
          1. Maybe you have a new site without a lot of reviews.<\/li>\n
          2. The following code will hide the ‘no Reviews’ text\n

            [php]
            \nfunction _gd_custom_hide_no_review_text( $class ) {
            \n global $post;
            \n if ( empty( $post->rating_count ) ) {
            \n $class .= ‘gd-custom-no-review’;
            \n }
            \n return $class;
            \n}
            \nadd_filter( ‘geodir_post_view_article_extra_class’, ‘_gd_custom_hide_no_review_text’, 10, 1 );
            \n[\/php]<\/p>\n

            And this short bit of CSS
            \n.gd-custom-no-review .geodir-entry-meta a.geodir-pcomments {
            \ndisplay: none !important;
            \n}<\/code><\/li>\n<\/ol>\n

            <\/a>Snippet to Remove GeoDirectory Scripts<\/h3>\n

            Some site owner may want to optimize their site by loading GD scripts only on GD pages. The following applies only to GD core. Each Addon has additional scripts.
            \nIn GD core most of the scripts and styles are loaded via geodir_templates_scripts() and geodir_templates_styles() functions. You can use the following to skip loading of GD Core scripts.<\/p>\n

            [php]
            \nremove_action( ‘wp_enqueue_scripts’, ‘geodir_templates_scripts’ );
            \nremove_action( ‘wp_enqueue_scripts’, ‘geodir_templates_styles’, 8 );
            \n[\/php]<\/p>\n

            geodir_is_geodir_page()<\/code> is used to identify the GD page<\/p>\n

            Here’s a Snippet that will execute only on GD Pages.
            \n*Caution* – Snippet below is only capable of detecting GD Pages, and will not detect other WP pages where you might be using a shortcode or widget. Use with Caution!<\/p>\n

            [php]
            \nadd_action( ‘wp’, ‘wpdocs_dequeue_script’, 100 );
            \nfunction wpdocs_dequeue_script() {
            \n if (!geodir_is_geodir_page()){
            \n remove_action(‘wp_enqueue_scripts’, ‘geodir_templates_scripts’);
            \n remove_action(‘wp_enqueue_scripts’, ‘geodir_templates_styles’, 8);
            \n }
            \n}
            \n[\/php]<\/p>\n

            <\/a>Common Code Snippets for Supreme Directory<\/h3>\n

            See the Supreme Directory FAQ page<\/a><\/p>\n

            <\/a>Showing icons instead of category links in list and grid view<\/h3>\n

            Let’s change this
            \n\"\"
            \ninto this
            \n\"\"<\/p>\n

              \n
            1. Make sure to add categories<\/strong><\/em> to the Listings pages<\/strong><\/em>, as explained here<\/a>:
              \n\"\"<\/li>\n
            2. Now add this PHP code as a new Code Snippet<\/a> or to your child theme’s functions.php<\/strong><\/em>:\n

              [php]
              \nfunction _gd_custom_listing_view_category_icon( $html, $location, $cf ) {
              \n global $post, $_gd_custom_term_icons;<\/p>\n

              $html_var = $cf[‘htmlvar_name’];<\/p>\n

              if ( !empty( $post->post_type ) && $html_var == $post->post_type . ‘category’ && !empty( $post->{$html_var} ) ) {
              \n if ( empty( $_gd_custom_term_icons ) ) {
              \n $_gd_custom_term_icons = geodir_get_term_icon();
              \n }<\/p>\n

              $post_taxonomy = $post->post_type . ‘category’;
              \n $field_value = $post->{$html_var};
              \n $links = array();
              \n $terms = array();

              if (!empty($field_value)) {

              if ($term != ”) {
              \n $term = get_term_by(‘id’, $term, $html_var);
              \n if (is_object($term)) {
              \n $term_icon_url = ! empty( $_gd_custom_term_icons ) && isset( $_gd_custom_term_icons[ $term->term_id ] ) ? $_gd_custom_term_icons[ $term->term_id ] : ”;
              \n $term_link = ‘<a title="’ . esc_attr( $term->name ) . ‘" href="’ . esc_attr(get_term_link($term, $post_taxonomy)) . ‘"><img src="’ . $term_icon_url . ‘" alt="’ . esc_attr( $term->slug ) . ‘ icon" class="_gd-custom-cat-icon" \/><\/a>’;

              if ($html_value != ”) {
              \n $field_icon = geodir_field_icon_proccess($cf);
              \n if (strpos($field_icon, ‘http’) !== false) {
