# Using the Redux WP_Filesystem Proxy

Redux has a WordPress filesystem proxy built in to help you read and write files that will pass Theme Check. These calls are available the moment a Redux object has been loaded (your Redux config has been run).

# Getting Started

First, you must get the Redux object. The easiest method is as follows:

$redux = Redux::get_instance('OPT_NAME'); // TODO - Use your opt_name

Once the Redux object has been obtained, the filesystem is now available to use. It's easy to do. Run the following call:

$redux->filesystem->execute( 'action', PATH, $args );

Below is a list of available commands and the arguments associated with each.

# Chmod / File Permissions

By default the WP_FileSystem API uses default values for chmod (read/write permissions). These are in the form of the declared FS_CHMOD_DIR for directories or FS_CHMOD_FILE for files. Do not worry about setting these values yourself.

TIP

If you must override the default chmod settings, you may pass in a chmod argument for all actions except object and unzip. To do so, pass a string or int: 0644 as this argument value.

# Possible Calls & Arguments.

# mkdir

Creates a directory. It will even make multiple children directories even it if doesn't exist.

$redux = Redux::get_instance( 'OPT_NAME' ); // TODO - Use your opt_name
$path = "THE_PATH"; // TODO - Replace with path
if ( ! is_dir( $path ) ) {
  $redux->filesystem->execute( "mkdir", $path );
}

# copy

Copies files from one location to another.

name type required description
destination string required The destination file path.
overwrite boolean optional Overwrite the files if exist, or by default the WP_FileSystem will skip existing if the file exists.
$redux = Redux::get_instance('OPT_NAME'); // TODO - Use your opt_name
$path = "THE_PATH"; // TODO - Replace with path
$destination = "DESTINATION_PATH"; // TODO - Replace with target/destination path

$redux->filesystem->execute( 
	'copy', 
	$path,
	array( 
		'destination' => $destination // TODO - Replace with target/destination path
	) 
);

# put_contents

The same as file_put_contents in PHP, but uses the WordPress filesystem API. Writes the contents of a variable to file. This will override any file if it already exists.

name type required description
content string required The content of the file.
$redux = Redux::get_instance('OPT_NAME'); // TODO - Use your opt_name
$path = "THE_PATH"; // TODO - Replace with path
$contents = "This is the content of the file." # TODO - Replace with contents

$redux->filesystem->execute( 
	'put_contents', 
	$path,
	array( 
		'content' => $contents
	) 
);

# get_contents

Retrieves the contents of a file. This command will attempt to use the WordPress filesystem first. However, if the file does not have the standard WordPress read permissions, it will fallback to file_get_contents.

$redux = Redux::get_instance('OPT_NAME'); // TODO - Use your opt_name
$path = "THE_PATH"; // TODO - Replace with path

$file_contents = $redux->filesystem->execute( 
	'get_contents', 
	$path
);

# object

Return a valid WordPress FileSystem API object.

$redux = Redux::get_instance('OPT_NAME'); // TODO - Use your opt_name
$object = $redux->filesystem->execute( 'object' );

# unzip

Unzips an existing zip file to a new location.

# Arguments
name type required description
destination string required The destination to unzip the zip file contents.
$redux = Redux::get_instance('OPT_NAME'); // TODO - Use your opt_name
$path = "THE_PATH"; // TODO - Replace with path
$destination = "DESTINATION_PATH"; // TODO - Replace with target/destination path

$redux->filesystem->execute( 
	'unzip', 
	$path, 
	array( 
		'destination' => $destination 
	) 
);
