Question

我正在使用此前端代码创建帖子。目前它确实创建了一个帖子，但唯一有效的是标题。

我的帖子中也有一些带有一些字段（more_info，priority和duedate等）的自定义元数据框，但我不确定我是否正确地将它们放入数组中。请注意，在后端，这些附加字段可以正常工作。

这是我的代码：

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

if (isset ($_POST['title'])) {
    $title =  $_POST['title'];
} else {
    echo 'Please enter a title';
}
if (isset ($_POST['description'])) {
    $description = $_POST['description'];
}

// Add the content of the form to $post as an array
$post = array(
    'post_title'      => $title,
    'post_content'  => $description,
    'more_info'    => $more_info,
    'priority'      => $priority,
    'duedate'       => $duedate,
    'post_category'   => $_POST['cat'],
    'post_status'    => 'publish',
    'post_type'    => $_POST['post']
);
wp_insert_post($post);
}
do_action('wp_insert_post', 'wp_insert_post'); 

?>

<form action="" id="new_post" method="post">
<label for="title">Task Name </label>
<input type="text" id="title" name="title" value="" />

<label for="minfo">Additional information</label>
<textarea name="minfo" id="minfo" value=""></textarea>

<label>Due date</label>
<input type="text" id="duedate" name="duedate" />


    <strong>Priority</strong>
    <label><input type="radio" name="priority" value="low" id="low">Low</label>
    <label><input type="radio" name="priority" value="normal" id="normal" checked>Normal</label>
    <label><input type="radio" name="priority" value="high" id="high">High</label>
    <label><input type="radio" name="priority" value="urgent" id="urgent">Urgent</label>

<input type="submit" name="submit" value="Add" />

<input type="hidden" name="cat" id="cat" value="<?php echo $cat_id = get_query_var('cat'); ?>" />
<input type="hidden" name="post_type" id="post_type" value="post" />
<input type="hidden" name="action" value="post" />
<?php wp_nonce_field( 'new-post' ); ?>

</form>

任何帮助都会很棒。

好的，偶然的事情：

我不清楚你在这里要做什么。您是否需要用户能够将此元框中提交的值添加到任何帖子中？如果没有，为什么不创建一个可以根据内心调整的自定义帖子类型？

如果对＃1的回答是肯定的，那么您仍然希望以不同方式附加保存方法。类似的东西：

add_meta_box(
    'my-custom-meta', // Unique ID
    esc_html__('Custom Attributes', 'my_scope'), // Title
    'my_custom_meta_box', // Callback function
    'post', // Admin page (or post type)
    'normal', // Context
    'high' // Priority
);


function my_custom_meta_box( $object ) { ?>

    <?php wp_nonce_field( 'my_custom_inner', 'my_custom_inner_nonce' ); ?>

    <p>
        <label for="minfo">Additional information</label>
        <textarea name="minfo" id="minfo" value="<?php echo esc_attr( get_post_meta( $object->ID, 'minfo', true ) ); ?>"></textarea>
    </p>
    <p>
        <label>Due date</label>
        <input type="text" id="duedate" name="duedate" value="<?php echo esc_attr( get_post_meta( $object->ID, 'duedate', true ) ); ?>" />
    </p>
    <p>
        <strong>Priority</strong>
        <label><input type="radio" name="priority" value="low" id="low"<?php if ( get_post_meta( $object->ID, 'priority', true ) == 'low' ) { echo ' checked'; }?>>Low</label>
        <label><input type="radio" name="priority" value="normal" id="normal"<?php if ( get_post_meta( $object->ID, 'priority', true ) == 'normal' ) { echo ' checked'; }?>>Normal</label>
        <label><input type="radio" name="priority" value="high" id="high"<?php if ( get_post_meta( $object->ID, 'priority', true ) == 'high' ) { echo ' checked'; }?>>High</label>
        <label><input type="radio" name="priority" value="urgent" id="urgent"<?php if ( get_post_meta( $object->ID, 'priority', true ) == 'urgent' ) { echo ' checked'; }?>>Urgent</label>
    </p>

<?php }


function save_my_meta( $post_id ) {
    // Check if our nonce is set.
    if ( ! isset( $_POST['my_custom_inner_nonce'] ) )
        return $post_id;

    $nonce = $_POST['my_custom_inner_nonce'];

    // Verify that the nonce is valid.
    if ( ! wp_verify_nonce( $nonce, 'my_custom_inner' ) )
        return $post_id;

    // If this is an autosave, our form has not been submitted, so we don't want to do anything.
    if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE )
        return $post_id;

    // Check the user's permissions.
    if ( $_REQUEST['post_type'] == 'post' ) {
        if ( ! current_user_can( 'edit_post', $post_id ) )
            return $post_id;
    }

    /* Cast the returned vaiables to an array for processing */
    $my_meta['minfo'] = $_REQUEST['minfo'];
    $my_meta['duedate'] = $_REQUEST['duedate'];
    $my_meta['priority'] = $_REQUEST['priority'];

    foreach ( $my_meta as $key => $value ) { // Cycle through the $events_meta array!
        if(get_post_meta( $post_id, $key ) ) { // If the custom field already has a value
            update_post_meta( $post_id, $key, sanitize_text_field( $value ) );
        } else {
            add_post_meta( $post_id, $key, sanitize_text_field ( $value ) );
        }
        if( !$value ) delete_post_meta( $post_id, $key ); // Delete if blank
    }
}
add_action( 'save_post', 'save_my_meta' );

从前端发帖主要是工作
