Explanation
WordPress automatically saves different versions of your posts, known as revisions. This can be handy if you need to go back to an earlier version, but too many revisions can clutter your database. Here's how you can limit the number of revisions WordPress keeps for each post.
What This Code Does:
- It hooks into WordPress using something called a filter, specifically the 'wp_revisions_to_keep' filter.
- It sets a limit on the number of revisions to keep. In this case, the limit is set to 5.
- Every time a post is saved, WordPress will only keep the latest 5 revisions, discarding older ones.
This is a simple and effective way to manage your post revisions, keeping your WordPress database lean and efficient. Just remember, if you ever need more revisions, you can adjust the number in the code.
Code
<?php
// Limit the number of post revisions in WordPress
// Hook into 'wp_revisions_to_keep' filter to set the number of revisions
function wp_dudecom_limit_post_revisions( $num, $post ) {
// Set the number of revisions to keep
$revision_limit = 5;
// Return the desired number of revisions
return $revision_limit;
}
add_filter( 'wp_revisions_to_keep', 'wp_dudecom_limit_post_revisions', 10, 2 );
?>Instructions
File Location: functions.php or a custom plugin file
Prerequisites:
- Access to your WordPress theme's
functions.phpfile or a custom plugin file. - Basic understanding of how to edit WordPress files.
Implementation Steps:
- Backup Your Site: Before making any changes, ensure you have a backup of your WordPress site. This is a good practice to prevent data loss.
- Access Your WordPress Files: Use an FTP client or your hosting provider's file manager to access your WordPress files.
- Locate the File: Navigate to your theme's directory and find the
functions.phpfile, or open your custom plugin file if you prefer to use a plugin. - Edit the File: Open the
functions.phpfile or your plugin file in a text editor. - Insert the Code: Copy and paste the provided code snippet into the file. Ensure it is placed at the end of the file or in a logical section where similar functions are grouped.
- Save Changes: Save the file and upload it back to your server if using an FTP client.
- Test the Implementation: Create or edit a post in WordPress and save it multiple times. Check the revisions section to ensure only the latest 5 revisions are kept.
