我需要更改一个buddypress主题中的函数(wordpress)

标签: wordpress function buddypress

我正在使用buddypress主题[buddyboss](http://buddyboss.com/)。主要原因是这个主题能够管理图片库(效果很好)。

我现在想在members-loop中调用该picture-function。其中一位buddyboss-admins告诉我:

  

“你将需要buddy_boss_pics.php中的函数。具体来说,你需要使用函数buddyboss_pics_screen_picture_grid_content()从第285行开始。你需要编辑文件以使用members-loop,因为它目前使用的是display_user_id。”

这是函数的外观:

function buddyboss_pics_screen_picture_grid_content()
{
    global $bp, $wpdb, $bbpics;

    $wpdb->show_errors = BUDDY_BOSS_DEBUG;

    $img_size = is_active_sidebar( 'Profile' ) ? 'buddyboss_pic_med' : 'buddyboss_pic_wide';

    $gallery_class = is_active_sidebar( 'Profile' ) ? 'gallery has-sidebar' : 'gallery';

    $user_id = $bp->displayed_user->id;
    $activity_table = $wpdb->prefix."bp_activity";
    $activity_meta_table = $wpdb->prefix."bp_activity_meta";

    $pages_sql = "SELECT COUNT(*) FROM $activity_table a INNER JOIN $activity_meta_table am ON a.id = am.activity_id WHERE a.user_id = $user_id AND meta_key = 'bboss_pics_aid'";

    $bbpics->grid_num_pics = $wpdb->get_var($pages_sql);

    $bbpics->grid_current_page = isset( $_GET['page'] ) ? (int) $_GET['page'] : 1;

    // Prepare a SQL query to retrieve the activity posts 
    // that have pictures associated with them
    $sql = "SELECT a.*, am.meta_value FROM $activity_table a INNER JOIN $activity_meta_table am ON a.id = am.activity_id WHERE a.user_id = $user_id AND meta_key = 'bboss_pics_aid' ORDER BY a.date_recorded DESC";

    buddy_boss_log("SQL: $sql");

    $pics  = $wpdb->get_results($sql,ARRAY_A);

    $bbpics->grid_pagination = new BuddyBoss_Paginated( $pics, $bbpics->grid_pics_per_page, $bbpics->grid_current_page );

    buddy_boss_log("RESULT: $pics");

    // If we have results let's print out a simple grid
    if ( !empty( $pics ) )
    {
        $bbpics->grid_had_pics = true;
        $bbpics->grid_num_pics = count( $pics );

任何帮助都会很棒,因为我真的需要这样做!

未经测试 - 但试试这个:

在members-loop中,查找

                <?php
             /***
              * If you want to show specific profile fields here you can,
              * but it'll add an extra query for each member in the loop
              * (only one regadless of the number of fields you show):
              *
              * bp_member_profile_data( 'field=the field name' );
              */
            ?>

在关闭php标记之前添加这个?&gt;

             buddyboss_pics_members_loop( bp_get_member_user_id() );

将buddyboss_pics_screen_picture_grid_content()函数复制到members-loop的底部。

将它放在php标签之间并将名称更改为      buddyboss_pics_members_loop($ user_id)

并注释或删除     $ user_id = $ bp-&gt; displayed_user-&gt; id;

这里buddyboss_pics_screen_picture_grid_content()函数主要使用user_id并从数据库中获取图像。

很简单,你在member-loop.php文件中的while循环中调用了这个函数: buddyboss_pics_screen_picture_grid_content(bp_member_user_id())

这里传递此函数的参数member_user_id。

很少编辑下面的主要buddyboss_pics_screen_picture_grid_content()功能:

以下更改:

function buddyboss_pics_screen_picture_grid_content($user_id = null)
{

    //Remove this code
    $user_id = $bp->displayed_user->id;

    //Put new Code
    if (empty($user_id)) {
        $user_id = $bp->displayed_user->id;
    } else {
        $user_id = $user_id;
    }

}
