END OF LIFE

The pop-file component v2.1.0 is now end-of-life. The upload and dir sub-components have been forked and pushed into other repositories, respectively:

• popphp/pop-http (now the Pop\Http\Upload class)
• popphp/pop-dir (now the Pop\Dir\Dir class)

OVERVIEW

pop-file is a component for managing file uploads and easily traversing files within a directory. With file uploads, you can set fine-grain controls to manage specific upload parameters like file types and file size. Also, you can traverse directories recursively as well.

pop-fileis a component of the Pop PHP Framework.

INSTALL

Install pop-file using Composer.

composer require popphp/pop-file

BASIC USAGE

File uploads

Basic file upload

use Pop\File\Upload;

$upload = new Upload('/path/to/uploads');
$upload->useDefaults();

$upload->upload($_FILES['file_upload']);

// Do something with the newly uploaded file
if ($upload->isSuccess()) {
    $file = $upload->getUploadedFile();
} else {
    echo $upload->getErrorMessage();
}

The above code creates the upload object, sets the upload path and sets the basic defaults, which includes a max file size of 10MBs, and an array of allowed common file types as well as an array of common disallowed file types.

File upload names and overwrites

By default, the file upload object will not overwrite a file of the same name. In the above example, if $_FILES['file_upload']['name'] is set to 'my_document.docx' and that file already exists in the upload path, it will be renamed to 'my_document_1.docx'.

If you want to enable file overwrites, you can simply do this:

$upload->overwrite(true);

Also, you can give the file a direct name on upload like this:

$upload->upload($_FILES['file_upload'], 'my-custom-filename.docx');

And if you need to check for a duplicate filename first, you can use the checkFilename method. If the filename exists, it will append a '_1' to the end of the filename, or loop through until it finds a number that doesn't exist yet (_#). If the filename doesn't exist yet, it returns the original name.

$filename = $upload->checkFilename('my-custom-filename.docx');

// $filename is set to 'my-custom-filename_1.docx'
$upload->upload($_FILES['file_upload'], $filename);

Directory traversal

Traversing a directory

use Pop\File\Dir;

$dir = new Dir('my-dir');

foreach ($dir->getFiles() as $file) {
    echo $file;
}

If you want to traverse the directory recursively and get the full path of each file.

use Pop\File\Dir;

$dir = new Dir('my-dir', [
    'absolute'  => true,
    'recursive' => true
]);

foreach ($dir->getFiles() as $file) {
    echo $file;
}

The available boolean options for the $options array parameter are:

• 'absolute' => store the absolute, full path of the items in the directory
• 'relative' => store the relative path of the items in the directory
• 'recursive' => traverse the directory recursively
• 'filesOnly' => store only files in the object (and not other directories)

Emptying a directory

use Pop\File\Dir;

$dir = new Dir('my-dir');
$dir->emptyDir(true);

The true flag will remove the actually directory as well.
