Display the form

To display the form on any WP Post, Page, or widget, add the shortcode:

[user-submitted-posts]

Or, to display the form anywhere in your theme, add the template tag:

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

Important: When copy/pasting the shortcode, use the plain-text editor or block. Using the Visual/RTE Editor may introduce unwanted artifacts when copy/pasting from a web page. Specifically, if you copy the above shortcode and paste it directly into a visual editor or block, the shortcode may be wrapped in code tags. And when the shortcode is wrapped in code tags, the form will display very poorly on the front end.

Customize the form

There are three main ways to customize the form:

• Visit the plugin settings to show/hide fields, configure options, etc.
• Enable the custom form template (check out «Custom Submission Form» below)
• Developers can use action and filter hooks

Custom Submission Form

Out of the box, User Submitted Posts provides a highly configurable submission form. Visit the plugin settings to control which fields are displayed, configure options, and so forth.

There are cases however, where advanced form configuration may be required. In order to allow for this, USP makes it possible to create a custom submission form. Here are the steps:

First, copy these two plugin files:

/user-submitted-posts/resources/usp.css
/user-submitted-posts/views/submission-form.php

Then, paste those two files into a directory named /usp/ in your theme:

/wp-content/themes/your-theme/usp/usp.css
/wp-content/themes/your-theme/usp/submission-form.php

Lastly, visit the plugin settings and set the «Form style» option to «Custom Form + CSS».

You can now customize the two files as desired. The files will not be overwritten when the plugin is updated. For help with making basic changes to the custom form, check out the USP FAQs at Perishable Press.

Alternately, you can set the option «Form style» to «HTML5 Form + Disable CSS» to use the default USP form along with your own CSS. FYI: here is a list of USP CSS selectors.

Or, to go further with unlimited custom forms, check out USP Pro. USP Pro provides a form builder within the WP Admin Area, where you can add any fields, labels, text, and so forth.

Display submitted posts

User-submitted posts are handled by WordPress as regular WP Posts. So they are displayed along with your other posts according to your theme design.

Display custom fields

To display submitted custom fields, visit the plugin settings and configure the «Auto-Display» options.

Also, here is a Helper Plugin to display Custom Fields. It is designed for use with the Pro version, but also works great with the free version.

For more flexibility, you can use a variety of WP Template Tags (e.g., get_post_meta()) to display custom fields.

Display submitted images

To display submitted images, visit the plugin settings and configure the «Auto-Display» options.

Display a Featured Image

To display a Featured Image (aka Post Thumbnail) for each submitted post, visit the plugin settings > Image Uploads > Featured Image.

Shortcodes

User Submitted Posts provides a set of useful shortcodes. Check out the «Display the Form» panel in the plugin settings for examples and quick information.

[user-submitted-posts]                        : displays the form on any Post or Page
[usp-login-form]                              : displays a login/register/password form
[usp_display_posts]                           : displays list of all submitted posts
[usp_gallery]                                 : displays a gallery of all submitted images for the current post
[usp-reset-button url="https://example.com/"] : displays a button to reset the form
[usp_access cap="read" deny=""][/usp_access]  : limits access to specific user capability
[usp_visitor deny=""][/usp_visitor]           : limits access to visitors (not logged in) only
[usp_member deny=""][/usp_member]             : limits access to logged-in users

Here is more information about these shortcodes:

[user-submitted-posts]

Displays the post-submit form. This shortcode does not accept any attributes.

[usp-login-form]

Displays the login/register/password form. This shortcode does not accept any attributes.

To add Google reCaptcha to the form, you can use a free reCaptcha plugin, for example:

• reCaptcha by BestWebSoft
• Advanced Google reCAPTCHA

[usp_display_posts]

Displays a list of all submitted posts. This shortcode accepts two optional attributes, «userid» and «numposts». Examples:

[usp_display_posts]                           : default displays all submitted posts by all authors
[usp_display_posts userid="current"]          : displays all submitted posts by current logged-in user
[usp_display_posts userid="1"]                : displays all submitted posts by registered user with ID = 1
[usp_display_posts userid="Pat Smith"]        : displays all submitted posts by author name "Pat Smith"
[usp_display_posts userid="all"]              : displays all submitted posts by all users/authors
[usp_display_posts userid="all" numposts="5"] : limit to 5 posts from all users
[usp_display_posts post_type="page"]          : display only submitted pages

The shortcode attributes can be used to customize the post list as desired. Note that the Pro version of USP provides many more options for the display-posts shortcode.

[usp_gallery]

Note: This shortcode works only when added to a submitted post. It does nothing when added anywhere else.

Displays a gallery of all submitted images for the current post. Customize via the following attributes:

size    = image size as thumbnail, medium, large or full -> default = thumbnail
format  = whether to make the image a linked image       -> default = image (can use image or image_link)
target  = whether to open linked image in new tab        -> default = blank (can use blank or self)
class   = optional custom class name(s)                  -> default = none
number  = the number of images to display for each post  -> default = 100
post_id = an optional post ID to use                     -> default = false (uses global/current post)

[usp-reset-button]

Displays a button to reset the form. Accepts the following attributes:

class  = classes for the parent element (optional, default: none)
value  = link text (optional, default: "Reset form")
url    = the URL where your form is displayed (required, default: none)
custom = any attributes or custom code for the link element (optional, default: none)

Note that the url attribute accepts %%current%% for the current URL (useful when the form is displayed in the sidebar).

[usp_access]

Limits access to specific user capability. Example:

[usp_access cap="read"]
    Content for users that have "read" access
[/usp_access]

The cap attribute specifies the required capability or capabilities (comma-separated). This shortcode also accepts an optional deny attribute. The deny attribute displays a message to users who are denied access. Tip: to include markup in the deny message, you can use {tag} to display <tag>. Check out the «Display the Form» panel in the plugin settings for examples and more info.

[usp_visitor]

Limits access to visitors (not logged in) only. Example:

[usp_visitor]
    Content for for users who are not logged in
[/usp_visitor]

This shortcode accepts an optional deny attribute. The deny attribute displays a message to users who are denied access. Tip: to include markup in the deny message, you can use {tag} to display <tag>. Check out the «Display the Form» panel in the plugin settings for examples and more info.

[usp_member]

Limits access to logged-in users. Example:

[usp_member]
    Content for for users who are logged in
[/usp_member]

*/

usp_get_images()

These template tags should work out of the box when included in your theme template file(s). Keep in mind that for some of the tags to work, there must be some existing submitted posts and/or images available.

The source code for these tags is located in /library/template-tags.php and shortcode-login.php.

Content Restriction

USP provides three «Access Control» shortcodes to control access and restrict content. Here are some examples to give you an idea of how it works.

Display form and/or content only to users with a specific capability:

[usp_access cap="read" deny="Message for users without read capability"]
    [user-submitted-posts] // Put the USP form or any other content here.
[/usp_access]

Display form and/or any content to logged-in users:

[usp_member deny="Message for users who are not logged in"]
    [user-submitted-posts] // Put the USP form or any other content here.
[/usp_member]

Display form and/or any content to visitors only:

[usp_visitor deny="Message for users who are logged in"]
    [user-submitted-posts] // Put the USP form or any other content here.
[/usp_visitor]

You can add and use Access Control shortcodes on any WP Post or Page. Tip: you can find this information (and more) in the plugin settings > Display the Form > Access Control.
