Concrete5 - CMS :: Get all file inside a file manager folder programmatically - concrete5

Question

I have a folder structure likes this:
folder1
subfolder1
file1.pdf
file2.pdf
subfolder2
file3.pdf
file4.pdf
is there any way to retrieve all the pdf file's(programmatically) using the "folder1" id?

Answer 1

There is but make sure you don't go insanely deep with your folder structure, you don't want to go through hundreds of folders, hundreds of levels deep.
Here's the code
<?php
use Concrete\Core\Tree\Node\Type\FileFolder;
use Concrete\Core\File\FolderItemList;
// First grab the folder object
$folder = FileFolder::getNodeByName('Testing Folder');
if (is_object($folder)) {
$files = [];
// if we have a folder we need to grab everything inside and then
// recursively go through the folder's content
// if what we get is a file we list it
// otherwise if it's another folder we go through it as well
$walk = function ($folder) use (&$files, &$walk) {
$list = new FolderItemList();
$list->filterByParentFolder($folder);
$list->sortByNodeName();
$nodes = $list->getResults();
foreach ($nodes as $node) {
if ($node->getTreeNodeTypeHandle() === 'file'){
$files[] = $node->getTreeNodeFileObject();
} elseif ($node->getTreeNodeTypeHandle() === 'file_folder'){
$walk($node);
}
}
};
$walk($folder);
// we are done going through all the folders, we now have our file nodes
foreach ($files as $file) {
echo sprintf('%sfile name is %s and URL is %s%s', '<p>', $file->getTitle(), $file->getURL(), '</p>');
}
}
