我想我有一个有点离经叛道的问题。我有一个函数可以向mysql数据库添加一条记录，其中包含位置lat和lng信息。但是，有时该函数工作不正常，导致无法创建db记录。因此，我想创建一个循环来不断检查函数是否创建了db记录，如果没有，请再次执行该函数。只是想说清楚；我使用的函数是一个默认的geomywp函数（reference）。有时它不能正常工作，我猜是由于谷歌Mapapi的响应时间。
我的functions.php中有以下内容，它似乎正在工作。我真的很想知道这是否是一个适当的方式来完成上述，因为我不确定。谢谢

global $wpdb;
$myccount = $wpdb->get_var($wpdb->prepare("SELECT COUNT(*) FROM ".$wpdb->prefix."gmw_locations WHERE object_id = %d", $post_id));
    if ($myccount <= 0) :
      while ($myccount <= 0) :
         gmw_pt_update_location( $args ); //The function I would like to check.
         $myccount = $wpdb->get_var($wpdb->prepare("SELECT COUNT(*) FROM ".$wpdb->prefix."gmw_locations WHERE object_id = %d", $post_id));
      endwhile;
    endif;

下面是我在为cpt创建post时用于导入地址的函数

function gmw_update_post_type_post_location(  $post_id ) {

    // Return if it's a post revision
    if ( false !== wp_is_post_revision( $post_id ) )
        return;

    // check autosave //
    if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) {
        return;
    }

    //check if user can edit post
    if ( !current_user_can( 'edit_post', $post_id ) )
        return;
    //Add post Meta
    add_post_meta($post_id, 'address', $_POST['address'], false);

    //get the address from the custom field "address"
    $addressarray = get_post_meta( $post_id, 'address', true );
    $address = $addressarray[0];
    //$address = $_POST['address'];

    //varify that address exists. Otherwise abort the function.
    if ( empty( $address ) )
        return;

    //include the update location file file
    include_once( GMW_PT_PATH .'/includes/gmw-pt-update-location.php' );

    //make sure the file included and the function exists
    if ( !function_exists( 'gmw_pt_update_location' ) )
        return;

    //Create the array that will pass to the function
    $args = array(
            'post_id' => $post_id, //Post Id of the post 
            'address' => $address // the address we pull from the custom field above
    );
    //Start counting 1
    global $wpdb;
    $myccount = $wpdb->get_var($wpdb->prepare("SELECT COUNT(*) FROM ".$wpdb->prefix."gmw_locations WHERE object_id = %d", $post_id));
    if ($myccount <= 0) :
    while ($myccount <= 0) :
    //Add location
    gmw_pt_update_location( $args );

    //Start counting 2
    $myccount = $wpdb->get_var($wpdb->prepare("SELECT COUNT(*) FROM ".$wpdb->prefix."gmw_locations WHERE object_id = %d", $post_id));
    endwhile;
    endif;
}
//execute the function whenever post type is being updated
add_action( 'save_post_mpp-gallery', 'gmw_update_post_type_post_location', 13, 1 );

将记录插入数据库的函数是：gmw\u update\u location这个函数可以在geomywp插件中找到。请参见此链接以获取一些参考：https://github.com/fitoussi/geo-my-wp/blob/master/includes/gmw-location-functions.php#lc194
