it's my first question on Stack network so let me know if something wrong in the use of this.

I have a theme with these pieces of code:

/**
 * Get the Featured image URL of a post
 * @global object $post
 * @param int $post_id
 * @return string
 */
function kleo_get_post_thumbnail_url( $post_id = null ) {
    $image_url = '';

    $thumb = get_post_thumbnail_id( $post_id );
    //all good. we have a featured image
    $featured_image_url = wp_get_attachment_url( $thumb );
    if ( $featured_image_url ) {
        $image_url = $featured_image_url;
    } elseif ( sq_option( 'blog_get_image', 1 ) == 1 ) {
        global $post;
        if (! is_object($post) && $post_id != NULL  ) {
            $post = setup_postdata( get_post($post_id) );
        }
        ob_start();
        ob_end_clean();
        if (isset($post->post_content)) {
            $output = preg_match_all('|<img.*?src=[\'"](.*?)[\'"].*?>|i', $post->post_content, $matches);
            $image_url = isset($matches[1][0]) ? $matches[1][0] : null;
        }
    }

    //Defines a default image
    if ( empty( $image_url ) )  {
        $image_url = sq_option_url('blog_default_image', '');
    }

    return $image_url;
}

This code return the Custom featured image url if exists, the blog default image (set in theme option panel) if custom img not exists.

In this code there's not filter for post_type which means the Default image is not only for 'post', but also 'page', 'attachment', 'revision', 'nav_menu_item' and every custom post type i have.

Now the problem is in the thumbnail for post_type in search result, managed by this code:

if(!function_exists('kleo_ajax_search'))
{
    function kleo_ajax_search()
    {
        //if "s" input is missing exit
        if( empty( $_REQUEST['s'] ) && empty( $_REQUEST['bbp_search'] ) ) die();

        if( ! empty( $_REQUEST['bbp_search'] ) ) {
            $search_string = $_REQUEST['bbp_search'];
        } else {
            $search_string = $_REQUEST['s'];
        }

        $output = "";
        $context = "any";
        $defaults = array(
            'numberposts' => 4,
            'posts_per_page' => 20,
            'post_type' => 'any',
            'post_status' => 'publish',
            'post_password' => '',
            'suppress_filters' => false,
            's' => $_REQUEST['s']
        );

        if ( isset( $_REQUEST['context'] ) && $_REQUEST['context'] != '' ) {
            $context = explode( ",", $_REQUEST['context'] );
            $defaults['post_type'] = $context;
        }

        $defaults =  apply_filters( 'kleo_ajax_query_args', $defaults);

        $the_query = new WP_Query( $defaults );
        $posts = $the_query->get_posts();

        $members = array();
        $members['total'] = 0;
        $groups = array();
        $groups['total'] = 0;
        $forums = FALSE;


        //if there are no posts, groups nor members
        if( empty( $posts ) && $members['total'] == 0 && $groups['total'] == 0 && ! $forums  ) {
            $output  = "<div class='kleo_ajax_entry ajax_not_found'>";
            $output .= "<div class='ajax_search_content'>";
            $output .= "<i class='icon icon-exclamation-sign'></i> ";
            $output .= __("Sorry, we haven't found anything based on your criteria.", 'kleo_framework');
            $output .= "<br>";
            $output .= __("Please try searching by different terms.", 'kleo_framework');
            $output .= "</div>";
            $output .= "</div>";
            echo $output;
            die();
        }


        //if there are posts
        if( ! empty( $posts ) ) {
            $post_types = array();
            $post_type_obj = array();
            foreach ( $posts as $post ) {
                $post_types[$post->post_type][] = $post;
                if (empty($post_type_obj[$post->post_type])) {
                    $post_type_obj[$post->post_type] = get_post_type_object($post->post_type);
                }
            }

            foreach ($post_types as $ptype => $post_type) {
                $output .= '<div class="kleo-ajax-part kleo-ajax-type-' . esc_attr( $post_type_obj[$ptype]->name ) . '">';
                if (isset($post_type_obj[$ptype]->labels->name)) {
                    $output .= "<h4><span>" . $post_type_obj[$ptype]->labels->name . "</span></h4>";
                } else {
                    $output .= "<hr>";
                }
                $count = 0;
                foreach ($post_type as $post) {

                    $count++;
                    if ($count > 4) {
                        continue;
                    }
                    $format = get_post_format( $post->ID );
                    if ( $img_url = kleo_get_post_thumbnail_url( $post->ID ) ) {
                        $image = aq_resize( $img_url, 44, 44, true, true, true );

                        }
                        $image = '<img src="'. $image .'" class="kleo-rounded">';
                    } else {
                        if ($format == 'video') {
                            $image = "<i class='icon icon-video'></i>";
                        } elseif ($format == 'image' || $format == 'gallery') {
                            $image = "<i class='icon icon-picture'></i>";
                        } else {
                            $image = "<i class='icon icon-link'></i>";
                        }
                    }

                    $excerpt = "";

                    if ( ! empty($post->post_content) ) {
                        $excerpt = char_trim( trim(strip_tags(strip_shortcodes($post->post_content))), 40, "..." );

                    $link = apply_filters('kleo_custom_url', get_permalink($post->ID));
                    $classes = "format-" . $format;

                }
                $output .= '</div>';
            }

            $output .= "<a class='ajax_view_all' href='" . home_url( '/' ) . '?s=' . $search_string . "'>" . __('View all results', 'kleo_framework') . "</a>";
        }

For every 'post_type' i get the same Blog Default image.

Could anyone explain to me how to filter the post_type or how to show sq_option( 'blog_get_image') only to 'post' in search results?

Thanks

If you look at your code, you see that parameters for a WP_Query are defined in $defaults.

There is also 'post_type' => 'any' defined which could be changed to 'post_type' => 'post' to query only for posts, not pages etc.

As you see later on, the search function redefines the post_type to $context based.

After this you could set it back with $defaults['post_type'] = 'post'; or find out how to use $context for your use...

You could also remove post_type from the $defaults-array, as returning only posts is the default behaviour of WP_Query.

Have a look at the Codex to learn more about WP_Query and especially Type Parameters.

  • I know that and i have read the codex for queries with WP_Query. The problem is that i have the same "blog_image_default" for blog post, page post and other "any" post type and i don't know how/where to filter the thumbnail images. – Riklisci Feb 15 '16 at 16:27
