我正在wordpress构建中使用自定义帖子类型、元框和；分类法。有一种更简单的方法可以做到这一点。。我还在学习，这是我第一次尝试。不管怎样，我都快完成了，但我想添加一些功能来帮助我的客户机（使其更易于使用）。

我有一个自定义的元框是“日期”，原因是播客的上载日期（即\\u日期）通常与播客录制的日期（元框\\u日期）不同。

我对php中的strotime函数略知一二，我很想用它来处理新播客上“date”字段的数据输入。现在它只是文本，所以如果用户输入“2012年1月23日”或“2012年1月23日”或“1-23-12”等，我就只能使用该文本进行显示。然而，使用strotime函数，我想我可以将用户输入转换为一个日期戳，我可以在网站上随意显示（m、d、y）。

我只是不知道从哪里开始——我对php非常陌生。我将在下面包含相关代码。如果您能提供任何帮助，我们将不胜感激！

谢谢

// Podcast Meta Box

function podcast_info() {
global $post;

// Noncename needed to verify where the data originated
echo \'<input id="podcastmeta_noncename" name="podcastmeta_noncename" type="hidden" value="\' .     wp_create_nonce( plugin_basename(__FILE__) ) . \'" />\';

// Get the data if its already been entered
$week = get_post_meta($post->ID, \'_week\', true);
$date = get_post_meta($post->ID, \'_date\', true);
$description = get_post_meta($post->ID, \'_description\', true);

// Echo out the field
echo \'<strong>Week</strong><br /><em>What week of the series is this podcast? (enter the &lsquo;Week X&rsquo; OR &lsquo;Guest Speaker&rsquo;)</em>\';
echo \'<input class="widefat" name="_week" type="text" value="\' . $week  . \'" />\';
echo \'<strong>Date</strong><br /><em>Enter the Date the podcast was recorded (Format as: &lsquo;mm/dd/yy&rsquo;)</em>\';

echo \'<strong>Description</strong><br /><em>Enter the text you\\\'d like to display as a description on the media archives list.</em>\';
echo \'<input class="widefat" name="_description" type="text" value="\' . $description  . \'" />\';

}

// Save the Podcast Meta box Data

function save_podcast_meta($post_id, $post) {

// verify this came from the our screen and with proper authorization,
// because save_post can be triggered at other times
if ( !wp_verify_nonce( $_POST[\'podcastmeta_noncename\'], plugin_basename(__FILE__) )) {
return $post->ID;
}

// Is the user allowed to edit the post or page?
if ( !current_user_can( \'edit_post\', $post->ID ))
    return $post->ID;

// OK, we\'re authenticated: we need to find and save the data
// We\'ll put it into an array to make it easier to loop though.
$podcast_meta[\'_week\'] = $_POST[\'_week\']; 
$podcast_meta[\'_date\'] = $_POST[\'_date\'];
$podcast_meta[\'_thumbnail\'] = $_POST[\'_thumbnail\'];
$podcast_meta[\'_seriesimg\'] = $_POST[\'_seriesimg\'];
$podcast_meta[\'_description\'] = $_POST[\'_description\'];

// Convert _date to actual date stamp

foreach ($podcast_meta as $key => $value) {
    if(get_post_meta($post->ID, \'_date\', true))
        strtotime(\'_date\');
}

// Add values of $podcast_meta as custom fields

foreach ($podcast_meta as $key => $value) { // Cycle through the $podcast_meta array!
    if( $post->post_type == \'revision\' ) return; // Don\'t store custom data twice
    $value = implode(\',\', (array)$value); // If $value is an array, make it a CSV (unlikely)
    if(get_post_meta($post->ID, $key, FALSE)) { // If the custom field already has a value
        update_post_meta($post->ID, $key, $value);
    } else { // If the custom field doesn\'t have a value
        add_post_meta($post->ID, $key, $value);
    }
    if(!$value) delete_post_meta($post->ID, $key); // Delete if blank
}

}
add_action(\'save_post\', \'save_podcast_meta\', 1, 2); // save the custom fields

EDIT - Working Now - See Code Below

<!-- Convert Date to Date Stamp -->
<?php $podcast_date = get_post_meta($post->ID, \'_date\', true);?>
<?php $fixed_date = strtotime($podcast_date); ?>

<!-- Display Date -->
<?php echo date(\'m/d/y\' , $fixed_date) ; ?>
