wp_upload_bits( string $name, null|string $deprecated, string $bits, string $time = null ): array

Creates a file in the upload folder with given content.

Description

If there is an error, then the key ‘error’ will exist with the error message.
If success, then the key ‘file’ will have the unique file path, the ‘url’ key will have the link to the new file. and the ‘error’ key will be set to false.

This function will not move an uploaded file to the upload folder. It will create a new file with the content in $bits parameter. If you move the upload file, read the content of the uploaded file, and then you can give the filename and content to this function, which will add it to the upload folder.

The permissions will be set on the new file automatically by this function.

    If you have multiple files upload, you must get length of arrays in your $_FILES array, after that loop with for.

        
if(isset($_FILES['your_field'])){
        $length = sizeof($_FILES['your_field']['name']);

        for ($i=0; $i < $length; $i++) { 
            wp_upload_bits($_FILES['your_field']['name'][$i], null, file_get_contents($_FILES['your_field']['tmp_name'][$i]));
        }

    HOW TO UPLOAD FILES TO A CUSTOM DIRECTORY IN WORDPRESS
    This example uploads a PDF document in the wp-content/uploads/customDirectory folder

    <form action="" method="post" enctype="multipart/form-data">
  Select image to upload:
  <input type="file" name="fileToUpload" id="fileToUpload">
  <br>
  <input type="submit" value="Upload Image" name="submittheform">
</form>

global $wp_filesystem;
WP_Filesystem();

$content_directory = $wp_filesystem->wp_content_dir() . 'uploads/';
$wp_filesystem->mkdir( $content_directory . 'CustomDirectory' );
$target_dir_location = $content_directory . 'CustomDirectory/';

if ( isset( $_POST['submittheform'] ) && isset( $_FILES['fileToUpload'] ) ) {
    $name_file = $_FILES['fileToUpload']['name'];
    $tmp_name = $_FILES['fileToUpload']['tmp_name'];

    if ( move_uploaded_file( $tmp_name, $target_dir_location . $name_file ) ) {
        echo "File was successfully uploaded";
    } else {
        echo "The file was not uploaded";
    }

    Basic Example
    A simple example assuming the request was made from a form with a file field called field1:

    $upload = wp_upload_bits($_FILES["field1"]["name"], null, file_get_contents($_FILES["field1"]["tmp_name"]));

    The function attempts to save a copy of the uploaded file to the upload directory set in the WordPress settings. It also performs security checks (file type, size, etc) and returns errors if any (see Return Values above). You might want to remove the tmp file after uploading.
