First, let me explain to you how to implement it.

To implement multiple file uploads, we can add multiple input file fields to the form, and then set the name attributes of these input files to the same name and name them in the form of an array, such as filename[]. As for the php code for file upload, it is the same as single file upload.

Let’s look at an example of multiple file upload:

html file example.html

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<body>
<form action="my_parser.php" method="post" enctype="multipart/form-data">
 <p><input type="file" name="file_array[]"></p>
 <p><input type="file" name="file_array[]"></p>
 <p><input type="file" name="file_array[]"></p>
 <input type="submit" value="Upload all files">
</form>
</body>
</html>

Copy after login

php file my_parser.php

<?php
if(isset($_FILES['file_array'])){
  $name_array = $_FILES['file_array']['name'];
  $tmp_name_array = $_FILES['file_array']['tmp_name'];
  $type_array = $_FILES['file_array']['type'];
  $size_array = $_FILES['file_array']['size'];
  $error_array = $_FILES['file_array']['error'];
  for($i = 0; $i < count($tmp_name_array); $i++){
    if(move_uploaded_file($tmp_name_array[$i], "test_uploads/".$name_array[$i])){
      echo $name_array[$i]." upload is complete<br>";
    } else {
      echo "move_uploaded_file function failed for ".$name_array[$i]."<br>";
    }
  }
}
?>
