Function to get files of same name from parent folder - php

Question

I've created custom elements for WPBakery. In the functions.php file, I currently have the following:
add_action( 'vc_before_init', 'vc_before_init_actions' );
function vc_before_init_actions() {
require_once('vc_elements/text-image/init.php' );
require_once('vc_elements/text/init.php' );
}
However, as I build more custom elements, that list will be huge. What I'm looking to do is load all files named init.php in each vc_elements subfolder.
This is my current folder structure:
vc_elements
text-image
init.php
text
init.php
What's the cleanest way to go about this?

Answer 1

You need to use RecursiveDirectoryIterator to scan the folder and get all files which are named as init.php. Below is the code you can use
add_action( 'vc_before_init', 'vc_before_init_actions' );
function vc_before_init_actions() {
$dir = '/full_path_to_vc_elements';
$files = getFiles($dir, 'init.php');
foreach( $files as $file) {
require_once( $file );
}
}
function getFiles($dir, $match) {
$return = array();
$iti = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dir));
foreach($iti as $file){
if ($file->isDir()) {
continue;
}
if(strpos($file , $match) !== false){
$return[] = $file->getPathname();
}
}
return $return;
}
So in future if you add any init.php file inside the folder, it will automatically be picked by getFiles() and included using require.

What I'm looking to do is load all files named init.php in each
vc_elements subfolder.
Assuming you mean only immediate sub-directorys of "vc_elements" you can use GlobIterator with an "*" as a subdirectory wildcard:
$myInitFiles = new GlobIterator('/path/to/vc_elements/*/init.php');
foreach ($myInitFiles as $file) {
require_once( $myInitFiles->key() );
}
unset($myInitFiles); // release object memory for garbage collection
You can obviously convert this to a more general function if required.

Perhaps something like this would work, assuming that directory only contains sub-directories with the elements you need.
$dir = 'path/to/vc_elements';
// Scan directory for its contents and put in array. Remove possiblity of . or ..
$files = array_diff(scandir($dir), array('..', '.'));
foreach ($files as $file) {
$name = '/path/to/vc_elements/' . $file . '/init.php';
include $name;
}

Not sure what the file structor is for your theme but if you have a folder like inc or int make a file called vc-functions.php in that file do something like this.
add_action( 'vc_before_init', 'vc_before_init_actions' );
function vc_before_init_actions() {
require_once('vc_elements/text-image/init.php' );
require_once('vc_elements/text/init.php' );
}
Then in the functions.php
require get_template_directory() . '/inc/vc-functions.php';
