WordPress Plugin: User Submitted Posts

[ User Submitted Posts ]

User Submitted Posts enables your visitors to submit posts and images from anywhere on your site via template tag or shortcode. User-submitted posts optionally include tags, categories, post titles, and more. You can set submitted posts as draft, publish immediately, or after some number of approved posts. Also enables users to upload multiple images when submitting a post. Everything super-easy to customize via Admin Settings page.

Update! Pro version of User Submitted Posts now available — check it out »

Let your visitors submit content

User Submitted Posts makes it easy to display a public post-submission form virtually anywhere on your site. Use the USP shortcode to display the submission form in any post or page, or use the USP template tag to include the form anywhere in your theme design. Visitors may then use the form to submit posts to your site. Depending on your preferences, user-submitted posts may include the following input fields:

  • Name
  • Email
  • URL
  • Post Title
  • Post Tags
  • Post Category
  • Post Content
  • Custom Field
  • Challenge Question
  • Google reCAPTCHA
  • Post Images

Using the Settings Page, you choose which fields to display, min/max number of images, min/max image size, redirect location, error messages and more. User Submitted Posts makes it easy to setup just about any type of user-submitted functionality for your WordPress-powered site. Here are some examples of how the USP plugin could be used:

  • Public Submit a Link form with tags
  • Simple Submit News form with post, title & author
  • Use as Contact Form that allows image attachments
  • Use as an Image Uploader, maybe with tags, title or whatever

Once a user has submitted a post, it’s saved as a “Draft” by default, but may optionally be set to “Publish Immediately” or even to publish if the author has “x” number of approved submissions. The plugin also displays a User Submitted Posts button at the top of the Posts Page that lets you filter all user-submitted posts/drafts with the click of a button.

Installation & Usage

Overview

  1. Install USP just like any other WordPress plugin
  2. Go to the “User Submitted Posts” settings and customize your options
  3. Display the submission form on your page(s) using template tag or shortcode

Displaying the submission form

To display the form on a post or page, use the shortcode:

[user-submitted-posts]

To display the form anywhere in your theme, use the template tag:

<?php if (function_exists('user_submitted_posts')) user_submitted_posts(); ?>

Customizing the submission form

  • To style the submission form, use the included CSS file located at: /resources/usp.css
  • To add custom JavaScript, use the included JS file located at: /resources/usp.js

Customizing user-submitted posts

User-submitted posts are just like any other post, with the exception that they each contain a set of custom fields. The custom fields include extra information about the post:

  • is_submission – indicates that the post is in fact user-submitted
  • user_submit_image – URLs of any submitted images (one field per image)
  • user_submit_ip – the IP address of the submitted-post author
  • user_submit_name – the name of the submitted-post author
  • user_submit_url – the submitted URL

So when user-submitted posts are displayed on your website, say on the home page or single-view, these custom fields are available to you in your theme files. This enables you to customize the user-submitted posts by displaying the submitted name, URL, images, and so forth. Here are two articles for those new to using WordPress custom-fields:

Template Tags

Additionally, the USP plugin also includes a set of template tags for customizing your user-submitted posts:

usp_is_public_submission()
Returns a boolean value indicating whether the specified post is a public submission
Usage: <?php if (function_exists('usp_is_public_submission')) usp_is_public_submission(); ?>

usp_get_post_images()
Returns an array of URLs for the specified post image
Usage: <?php $images = usp_get_post_images(); foreach ($images as $image) { echo $image; } ?>

usp_post_attachments()
Prints the URLs for all post attachments.
Usage:  <?php if (function_exists('usp_post_attachments')) usp_post_attachments(); ?>
Syntax: <?php if (function_exists('usp_post_attachments')) usp_post_attachments($size, $beforeUrl, $afterUrl, $numberImages, $postId); ?>
Paramters:
    $size         = image size as thumbnail, medium, large or full -> default = full
    $beforeUrl    = text/markup displayed before the image URL     -> default = <img src="
    $afterUrl     = text/markup displayed after the image URL      -> default = " />
    $numberImages = the number of images to display for each post  -> default = false (display all)
    $postId       = an optional post ID to use                     -> default = uses global post

usp_author_link()
For public-submitted posts, this tag displays the author's name as a link (if URL provided) or plain text (if URL not provided)
For normal posts, this tag displays the author's name as a link to their author's post page
Usage: <?php if (function_exists('usp_author_link')) usp_author_link(); ?>

For more tags, check out USP at WordPress.org, and/or the source code of the plugin file located at: /library/template-tags.php

  1. Awesome plugin, thanks. One strange thing, the ‘choose file’ button is not clickable from iphone 4s with Safari.

      Rob, that’s because iOS doesn’t allow access to files on the phone for browser uploading… It’s kind of a bummer for web-stuff.

    Have just downloaded this and am testing it now – it sounds like it’s exactly what I’ve been searcging for.

  3. Not showing user submitted url (Author URL).

    All other details showing correctly.
    Author Name
    Post Title
    Post Tags
    Post Category
    Post Content

    Do i need to add any short code to display Author URL ?

  4. Greetings. A great plugin.
    How can I show all images as a thumbnail, or at least 10-20 of them in my index page? And when someone clicks to go to the page the picture?

  5. fixed –
    <img src="ID, ‘user_submit_image’, true); ?>” />

    ;)

    Hi,

    Am having a play about with this. How can I add / customise specific error messages please?

  7. hi, how can i add new fields? like youtube url, twitter user name, facebook page etc.

  8. Hi, seems like a great plugin! i added without any problems. However, when you post images they are not showing up. I see them in the media folder, but they are not displayed on the page.

    Thanks,
    Allison

    • Hi, I found where to put the image code, but I need assistance with the code itself. Can you give an example of how to edit this?
      <?php post_attachments($size, $beforeUrl, $afterUrl, $numberImages, $postId); ?>

      For example, I want to put a <br> after the image. Everything else can be the default.
      Thanks!

    Hi,

    Could you advise how I can add in custom error messages please?

    E.g. “you need to provide an image that is XXX by XXX?” instead of the generic error message.

    That would be greatly appreciated.

    Thanks,
    Matt

  10. Hi looks like a great plugin but I can’t see the images in pending posts after a user has completed the form.

    Any ideas welcome!

  11. Hi, when the plugin displays your categories to choose to include in the form – it translates an Ampersand in the category name to ” &amp “.

    For example, the category “Banks & Financial Institutions” turns into “Banks & Financial Institutions”.

    Any idea how I can fix this?
