There might be a situation where you may want to allow your visitor to submit contents or articles or news of their own. Most of you might be thinking that ‘damn i shall find a plugin for this’, well this is not as hard as you think. You dont’ need to search for plugin. Writing code is easier than finding plugin and customizing it.
Follow the following simple steps ;
-
- Create a form with necessary fields i.e. title, content and featured image. Additional field could be : visitor first name, last name , email and category. Don’t forget to add nonce field because it protects the forms from certain types of misuse and malicious .

- Validate the form fields

- If the user exists, get the user id ; if the user doesn’t exist, insert the user in the database and get the id of the inserted user . Note : wp_insert_user() gives the user id of just inserted user
- Create a form with necessary fields i.e. title, content and featured image. Additional field could be : visitor first name, last name , email and category. Don’t forget to add nonce field because it protects the forms from certain types of misuse and malicious .

if(email_exists($email)) { /* check if the user already exist */ $userDetail = get_user_by( 'email', $email); $userID = $userDetail->ID; }else { /* if user doesn't exist create new user and the created user are subscriber*/ $userData = [ 'user_login' => $email, 'user_email' => $email, 'user_pass' => '1234@567', 'first_name' => $fName, 'last_name' => $lName, ]; $userID = wp_insert_user($userData); } |
4. Upload the attached file inside the uploads folder and get the id of the attached file .

$uploadDir = wp_upload_dir(); $file = $_FILES['featured' ]; $uploadFile = $uploadDir['path'] . '/' . basename(sanitize_file_name( $file['name']) ); if (file_exists($uploadFile)) { $uploadFile = $uploadDir['path'] . '/'.time().'-' . basename( sanitize_file_name($file['name'])); } move_uploaded_file( $file['tmp_name'] , $uploadFile ); $filename = basename( $uploadFile ); $wp_filetype = wp_check_filetype(basename($filename), null ); $attachment = array( 'post_mime_type' => $wp_filetype['type'], 'post_title' => preg_replace('/\.[^.]+$/', '', $filename), 'post_content' => '', 'post_status' => 'inherit', 'menu_order' => $_i + 1000 ); $attach_id = wp_insert_attachment( $attachment, $uploadFile ); |
5. Save the contents including featured image in the dashboard . Note : save the contents as a draft so that you can review the post and publish it later.

/* * Insert post */ $post = array( 'post_author' => $userID, 'post_title' => $newsTitle, 'post_content' => $_POST['content'], 'post_category' => array($cat), //'tags_input' => array($_POST['post_tags']), 'post_status' => 'draft', // Could be: publish 'post_type' => 'post' // Could be: `page` or your CPT ); $newsID = wp_insert_post($post); /* * set featured image for post */ set_post_thumbnail($newsID, $attach_id ); |
