Instruction

Install

Copy a code snippet above (without the opening php tag) and paste it to the functions.php file in the active theme directory.

Add shortcode

You can add the [um_profile_header] shortcode to the page/post content to display the page/post author like the header section of the Ultimate Member profile.

You can add this shortcode to the sidebar. The shortcode will be shown on the single (post) pages and will be hidden on archive (category) pages.

Attributes

Use optional attribute form_id to select a profile form you prefer if you created multiple profile forms.
Use optional attribute user_id to display the profile header for the certain user.

Examples

[um_profile_header]
[um_profile_header form_id="7"]
[um_profile_header form_id="7" user_id="1"]

@yuriinalivaiko could you explain to me why I get no_cover class for the user's post while the user has submitted their profile cover?

Edit: when I add a specific from ID it is showing. I think it's depending on this.

@demian1985
Maybe you have multiple profile forms with different settings. The shortcode gets settings from the first fount profile form if there is no form_id attribute.
