Are you using the Document Library Pro plugin by Barn2 on your WordPress site and wondering how to showcase documents based on the current logged-in user? In this guide, we’ll walk you through the process of modifying a hook to achieve just that. Please note that if the user is not logged in, the table will display all documents.
Understanding the Goal
The objective here is to customize the Document Library Pro plugin so that when a user is logged in, they see only the documents they have created. If a user is not logged in, the table should display all available documents.
Modifying the Hook
To accomplish this, we will make use of a filter hook provided by the Document Library Pro plugin. The filter we’ll be working with is document_library_pro_query_args
. This filter allows us to modify the arguments used in the query to fetch documents.
add_filter('document_library_pro_query_args', function($args, $posts_table) {
// Get the current user ID
$current_user_id = get_current_user_id();
// Modify the arguments to filter documents by the current user
if ($current_user_id) {
$args['author'] = $current_user_id;
}
return $args;
}, 10, 2);
In this code snippet, we use the get_current_user_id()
function to retrieve the ID of the currently logged-in user. We then check if a user is logged in. If so, we modify the query arguments to filter documents based on the user ID.
Implementation Steps
- Accessing Your WordPress Child Theme Functions: Navigate to your WordPress dashboard and go to “Appearance” > “Theme Editor.” In the Theme Editor, find and open the
functions.php
file. Make sure you don’t modify the parent theme files as those will be overridden with the next update. - Adding the Code Snippet: Paste the provided code snippet at the end of your
functions.php
file. Save the changes. - Testing the Implementation: Visit the page where you have the Document Library Pro table. If you’re logged in, you should now see only the documents associated with your user account. If you’re not logged in, the table will display all documents.
Conclusion
By modifying the document_library_pro_query_args
hook, you’ve successfully tailored the Document Library Pro plugin to show user-specific documents for logged-in users while displaying all documents for those who are not logged in. This customization enhances the user experience by providing personalized content based on individual document submissions.
