我想从前端提交自定义帖子。我已经做好了准备让这一切发生。但我想上传wordpress的特色图片表单添加媒体按钮。

代码为

<?php
/*
Template Name: post submition Template

Description: Use this page template to hide the sidebar. Alternatively
you can simply remove all widgets from your sidebar to hide it on
all pages.
*/
?>

<?php get_header(); ?>
<?php 

// Check if the form was submitted
if( \'POST\' == $_SERVER[\'REQUEST_METHOD\'] && !empty( $_POST[\'action\'] )) {

// Do some minor form validation to make sure there is content
if (isset ($_POST[\'title\'])) { 
    $title =  $_POST[\'title\']; 
} else { 
    echo \'Please enter a title\';
}
if (isset ($_POST[\'description\'])) { 
    $description = $_POST[\'description\']; 
} else { 
    echo \'Please enter the content\'; 
}

// Add the content of the form to $post as an array
$post = array(
    \'post_title\'    => $title,
    \'post_content\'  => $description,
    \'post_category\' => $_POST[\'cat\'],  // Usable for custom taxonomies too
    \'post_status\'   => \'draft\',         // Choose: publish, preview, future, etc.
    \'post_type\'     => \'contast\'  // Use a custom post type if you want to
);
echo $pid = wp_insert_post($post);  // Pass  the value of $post to WordPress the insert function

    if ($_FILES) {
array_reverse($_FILES);
$i = 0;//this will count the posts
foreach ($_FILES as $file => $array) {
    if ($i == 0) $set_feature = 1; //if $i ==0 then we are dealing with the first post
    else $set_feature = 0; //if $i!=0 we are not dealing with the first post
