Php 从前端表单更新自定义帖子元

Php 从前端表单更新自定义帖子元,php,wordpress,Php,Wordpress,这就是我如何在查询中获得自定义帖子元的方法 <?php $collections = get_post_meta( $post->ID, 'do_collection'); if( !$collections || !$collections[0] ) return; foreach ( $collections[0] as $collection ) : echo '<p

这就是我如何在查询中获得自定义帖子元的方法

<?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;
?>
现在我正试图从前端的表单中获取自定义的post元数据。 但当我从前端提交表单时,我会在管理区得到所有带有第一个字母的元字段

<?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>
用这个代替

$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);

元“do_集合”应该是多维数组吗? 如果没有,则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>';

确保转义您的$\u POST数据。感谢您的回复,但使用您的解决方案后仍然存在相同的问题。如果我在歌曲标题字段中编写测试,我会在所有字段中得到T。元“do_集合”应该是多维数组吗?如果没有,您可以更新检索元数据的方式:$collection=get\u post\u meta$post->ID,“do\u collection”,TRUE;如果$收款返还;回音“”.$collection['song-title']。

”;回音“”.$collection['song-category']。

”;回音“”.$collection['song-layrics']。

”;谢谢你的回答是可以接受的。我做了$collection[0]['song-title']=$\u POST['song-title'];它修好了。
