WordPress创建前端发布插件

Question

我尝试创建一个插件，允许用户从前端添加新帖子，编辑帖子和删除帖子。现在，当用户尝试编辑帖子而不是更新相同的帖子插件创建新的页面 !处于待定状态。有人能帮帮我吗?这是edit post类的代码:

<?php
/**
 * Edit Post form class
 *
 * @author Engr.MTH
 * @package MOSTASHAROON Frontend Form
 */
class MOSFF_Edit_Post {
    function __construct() {
        add_shortcode( 'mosff_editpost', array($this, 'shortcode') );
    }
    /**
     * Handles the edit post shortcode
     *
     * 
     */
    function shortcode() {

$query = new WP_Query(array('post_type' => 'post', 'posts_per_page' =>'-1', 'post_status' => array('publish', 'pending', 'draft', 'private', 'trash') ) );
if ($query->have_posts()) : while ($query->have_posts()) : $query->the_post();global $post;
    if(isset($_GET['post'])) {
        if($_GET['post'] == $post->ID)
        {
            $current_post = $post->ID;
            $title = get_the_title();
            $content = get_the_content();
            $custom_one = get_post_meta($current_post, 'vsip_custom_one', true);
            $custom_two = get_post_meta($current_post, 'vsip_custom_two', true);
        }
    }
endwhile; endif;
wp_reset_query();
global $current_post;
$postTitleError = '';
if(isset($_POST['submitted']) && isset($_POST['post_nonce_field']) && wp_verify_nonce($_POST['post_nonce_field'], 'post_nonce')) {
    if(trim($_POST['postTitle']) === '') {
        $postTitleError = 'Please enter a title.';
        $hasError = true;
    } else {
        $postTitle = trim($_POST['postTitle']);
    }
    $post_information = array(
        'ID' => $current_post,
        'post_title' => esc_attr(strip_tags($_POST['postTitle'])),
        'post_content' => esc_attr(strip_tags($_POST['postContent'])),
        'post-type' => 'post',
        'post_status' => 'pending'
    );
    $post_id = wp_update_post($post_information);
    if($post_id)
    {
        // Update Custom Meta
        update_post_meta($post_id, 'vsip_custom_one', esc_attr(strip_tags($_POST['customMetaOne'])));
        update_post_meta($post_id, 'vsip_custom_two', esc_attr(strip_tags($_POST['customMetaTwo'])));
        wp_redirect( home_url() ); exit;
    }
}
?>

    <!-- #primary BEGIN -->
    <div id="primary">
        <form action="" id="primaryPostForm" method="POST">
            <fieldset>
                <label for="postTitle"><?php _e('Post's Title:', 'framework') ?></label>
                <input type="text" name="postTitle" id="postTitle" value="<?php echo $title; ?>" class="required" />
            </fieldset>
            <?php if($postTitleError != '') { ?>
                <span class="error"><?php echo $postTitleError; ?></span>
                <div class="clearfix"></div>
            <?php } ?>
            <fieldset>
                <label for="postContent"><?php _e('Post's Content:', 'framework') ?></label>
                <textarea name="postContent" id="postContent" rows="8" cols="30"><?php echo $content; ?></textarea>
            </fieldset>
            <fieldset>
                <label for="customMetaOne"><?php _e('Custom Meta One:', 'framework') ?></label>
                <input type="text" name="customMetaOne" id="customMetaOne" value="<?php echo $custom_one; ?>" />
            </fieldset>
            <fieldset>
                <label for="customMetaTwo"><?php _e('Custom Meta Two:', 'framework') ?></label>
                <input type="text" name="customMetaTwo" id="customMetaTwo" value="<?php echo $custom_two; ?>" />
            </fieldset>
            <fieldset>
                <?php wp_nonce_field('post_nonce', 'post_nonce_field'); ?>
                <input type="hidden" name="submitted" id="submitted" value="true" />
                <button type="submit"><?php _e('Update Post', 'framework') ?></button>
            </fieldset>
        </form>

    </div><!-- #primary END -->
<?php }}
$mosff_editpostform = new MOSFF_Edit_Post();

Answer 1

我找到了答案，只是我删除了这一行:

global $current_post;

Answer 2

我认为您可以通过获取post id并查询它来获取特定的所有字段，并通过表单编辑它并再次发布它来做到这一点。
