How to let users submit content from the front end of WordPress

Questions

Can WordPress let visitors submit posts without a plugin?

Yes, but not through a ready-made front-end form. A developer must create the form and processing code, then use functions such as <code>wp_insert_post()</code> for the post, nonce checks for request protection and <code>media_handle_upload()</code> for files. This route is reasonable when you need a very specific workflow and can maintain the code.

Should front-end submissions publish immediately or wait for approval?

User-submitted content should normally wait in <code>pending</code> status until an editor reviews it. WordPress uses pending posts for content awaiting someone with publishing permission, so contributors do not need permission to publish directly. Automatic publishing is only sensible when the audience is trusted and your validation, spam controls and editorial process are already reliable.

How do I allow users to upload images with a front-end form?

Set the form's encoding to <code>multipart/form-data</code>, validate the request, restrict permitted file types and process the upload with <code>media_handle_upload()</code>. Create the post first so the attachment has a parent post, then save the attachment ID or set it as the featured image. Check upload errors and server size limits rather than assuming every image will succeed.

Can guests submit WordPress posts without registering?

Yes, a custom form or plugin can accept guest submissions, but guest access increases the need for moderation and anti-spam controls. Do not trust submitted author IDs, post statuses or post types. Validate every field, restrict uploads, use a nonce where applicable, rate-limit or challenge suspicious requests, and keep new content pending until someone reviews it.

Why does a front-end submission form appear to work but save no content?

The usual causes are incorrect field mapping, missing form encoding for uploads, failed nonce validation, insufficient permissions or an ignored <code>WP_Error</code> from <code>wp_insert_post()</code>. Check the server response and error logs, confirm that the submitted field names match the processing code, and test while logged in as the same role your contributors will use.
