在自定义发布类型中保存元数据

我不明白为什么这些函数在保存startdate和starttime时不保存价格和位置数据。当我打印（$custom）时，我可以看到[events\\u price]=>数组（[0]=>）为空。。

 function event_detail_box_content( $post ) {
    $custom = get_post_custom($post->ID);
    $meta_sd = $custom["events_startdate"][0];
    $meta_pr = $custom["events_price"][0];
    $meta_lo = $custom["events_location"][0];

    $meta_st = $meta_sd;

    $time_format = get_option(\'time_format\');

    if ($meta_sd == null) { $meta_sd = time(); $meta_st = 0;}

    $clean_sd = date("D, M d, Y", $meta_sd);
    $clean_st = date($time_format, $meta_st);

    echo \'<input type="hidden" name="events-nonce" id="events-nonce" value="\' . wp_create_nonce( \'events-nonce\' ) . \'" />\';

    ?>
    <div class="tf-meta">
    <ul>
        <li><label>Event Date</label><input name="events_startdate" class="tfdate" value="<?php echo $clean_sd; ?>" /></li>
        <li><label>Event Time</label><input name="events_starttime" value="<?php echo $clean_st; ?>" /><em>Use 24h format (7pm = 19:00)</em></li>
        <li><label>Event Price</label><input name="events_price" value="<?php echo $meta_pr; ?>" /></li>
        <li><label>Event Location</label><input name="events_location" value="<?php echo $meta_lo; ?>" /></li>
    </ul>
    </div>
    <?php
    print_r($custom);
 }

   add_action (\'save_post\', \'save_events\');

   function save_events($post_id){

    if ( !wp_verify_nonce( $_POST[\'events-nonce\'], \'events-nonce\' )) { return; }

    if ( !current_user_can( \'edit_post\')) return;

    if(!isset($_POST["events_startdate"])): return; endif;

    $updatestartd = strtotime ( $_POST["events_startdate"] . $_POST["events_starttime"] );
    update_post_meta($post_id, "events_startdate", $updatestartd ); 

    update_post_meta($post_id, "events_price", $POST["events_price"] ); 
    update_post_meta($post_id, "events_location", $POST["events_location"] ); 
 }

add_action( \'add_meta_boxes\', \'event_detail_box\' ); function event_detail_box() { add_meta_box( \'event_detail_box\', __( \'Event Detail\', \'myplugin_textdomain\' ), \'event_detail_box_content\', \'event\', \'normal\', \'high\' ); } function event_detail_box_content( $post ) { // No need to globalise a post that is an argument on this callback $meta_p = get_post_meta($post->ID, "events_price", true); $meta_l = get_post_meta($post->ID, "events_location", true); echo \'<input type="hidden" name="events-nonce" id="events-nonce" value="\' . wp_create_nonce( \'events-nonce\' ) . \'" />\'; ?> <div class="tf-meta"> <ul> <li><label>Event Price</label><input name="events_price" value="<?php echo $meta_p; ?>" /></li> <li><label>Event Location</label><input name="events_location" size="50" value="<?php echo $meta_l; ?>" /></li> </ul> </div> <?php } add_action (\'save_post\', \'save_events\'); // The save_post hook provides the post id to the return function function save_events( $post_id ){ if ( !wp_verify_nonce( $_POST[\'events-nonce\'], \'events-nonce\' )) { return $post_id; } if ( !current_user_can( \'edit_post\', $post_id )) return $post_id; update_post_meta($post_id, "events_price", $POST[\'events_price\'] ); update_post_meta($post_id, "events_location", $POST[\'events_location\'] ); }

function save_events( $post_id ){ if ( !wp_verify_nonce( $_POST[\'events-nonce\'], \'events-nonce\' )) { return $post_id; } if ( !current_user_can( \'edit_post\', $post_id )) return $post_id; update_post_meta($post_id, "events_price", $POST[\'events_price\'] ); update_post_meta($post_id, "events_location", $POST[\'events_location\'] ); }

为什么esc_url在SmartMetabox中不起作用

你试过吗http://www.wproots.com/ultimate-guide-to-meta-boxes-in-wordpress/ ? 创建metabox是一个很好的类。但我对验证有问题。我试过了sanitize_callback 参数来清理URL，所以我使用esc_url 但该字段仍然接受所有值。这里有什么问题？这是我的密码add_smart_meta_box( \'themename_slides_url\', array( \'title\' => _
