Question

这就是我在查询中获取自定义post meta的方式。

<?php 
        $collections = get_post_meta( $post->ID, 'do_collection');
        if( !$collections || !$collections[0] )
            return;
            foreach ( $collections[0] as $collection ) :
            echo '<p>'.$collection['song-title'].'</p>';
            echo '<p>'.$collection['song-category'].'</p>';
            echo '<p>'.$collection['song-layrics'].'</p>';
        endforeach;
?>

现在我正在尝试从前端的表单中获取自定义的后期元值。但是当我从前端提交表单时，我会在管理区域中获得带有第一个字母的所有元字段。

<?php 
if( 'POST' == $_SERVER['REQUEST_METHOD'] && !empty( $_POST['action'] ) &&  $_POST['action'] == "new_post") {

    $new_post = array(
    'post_status'   =>  'publish',
    'post_type' =>  'do_songs'
    );
    $pid = wp_insert_post($new_post);
    update_post_meta($pid, 'do_collection',  $_POST['song-title']);
    update_post_meta($pid, 'do_collection',  $_POST['song-category']);
    update_post_meta($pid, 'do_collection',  $_POST['song-layrics']);

    $link = get_permalink( $pid );
    wp_redirect( $link );
}
do_action('wp_insert_post', 'wp_insert_post');
?>

<div class="form-wrap">
<form id="new_post" name="new_post" method="post" action="" class="wpcf7-form" enctype="multipart/form-data">
    <fieldset>
        <label for="song-title">Song Title:</label>
        <input type="text" value="" tabindex="35" name="song-title" id="song-title" />
    </fieldset>
    <fieldset>
        <label for="song-category">Song Category:</label>
        <input type="text" value="" tabindex="35" name="song-category" id="song-category" />
    </fieldset>
    <fieldset>
        <label for="song-layrics">Song Layrics:</label>
        <input type="text" value="" tabindex="35" name="song-layrics" id="song-layrics" />
    </fieldset>
    <fieldset class="submit">
        <input type="submit" value="Post Review" tabindex="40" id="submit" name="submit" />
    </fieldset>
    <input type="hidden" name="action" value="new_post" />
    <?php wp_nonce_field( 'new-post' ); ?>
</form>
</div>

改为使用

$collection = array();
$collection['song-title'] = $_POST['song-title'];
$collection['song-category'] = $_POST['song-category'];
$collection['song-lyrics'] = $_POST['song-lyrics'];

update_post_meta($pid, 'do_collection', $collection);

meta＆＃39; do_collection＆＃39;应该是一个多维数组？如果没有，您可以更新检索元数据的方式：

$collection = get_post_meta( $post->ID, 'do_collection', TRUE);

if( !$collection ) return;

echo '<p>'.$collection['song-title'].'</p>';
echo '<p>'.$collection['song-category'].'</p>';
echo '<p>'.$collection['song-layrics'].'</p>';
