What is WordPress Hook: sanitize_file_name
The sanitize_file_name hook in WordPress is used to sanitize a file name. This means that it can be used to remove any special characters or spaces from a file name, making it safe for use in a URL or as a file name on the server.
Understanding the Hook: sanitize_file_name
The sanitize_file_name hook is located within the wp-includes/formatting.php file in WordPress. It is typically used when a file name is being processed, such as when uploading a file to the media library or when creating a new attachment.
Hook Parameters (if applicable): sanitize_file_name
The sanitize_file_name hook does not accept any arguments or parameters. It simply takes the file name as input and returns the sanitized version of the file name.
Hook Doesn’t Work: sanitize_file_name
If the sanitize_file_name hook doesn’t seem to be working, it could be due to conflicts with other plugins or themes that are also manipulating file names. It’s important to check for any other functions or filters that may be affecting the file name sanitization process.
Best Practices & Usage Notes (if applicable): sanitize_file_name
When using the sanitize_file_name hook, it’s important to keep in mind that it only sanitizes the file name itself and does not check for file existence or permissions. It’s also important to note that the hook should only be used for file names and not for other types of input data.
Usage Example: sanitize_file_name
“`php
$filename = “my file.jpg”;
$sanitized_filename = apply_filters( ‘sanitize_file_name’, $filename );
echo $sanitized_filename; // Output: my-file.jpg
“`
