Required steps to upload multiple files in PHP

Step 1:- First of all, create a PHP file inside the root directory of your local server such as index.php.
Step 2
:- Add the below code in the index.php file as shown below


<!DOCTYPE html>
<html lang="en">
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script>
<div class="container">
  <h3>PHP Upload Multiple Files Example</h3>
      <form action="upload.php" method="post" enctype="multipart/form-data">
          <div class="form-group">
            <label for="Upload">Upload File:</label>
            <input type="file" class="form-control" id="image" name="image[]">
          <input type="hidden" id="slno" value="0">
          <div id="add_row"></div>
          <div class="form-group">
            <button type="button" class="btn btn-success btn-sm" id="add">Add File</button>
          <div class="form-group">
            <button type="submit" class="btn btn-primary btn-sm pull-right" name="upload">Submit</button>
<script type="text/javascript">
  //add the banner field
      var add_id = $('#slno').val();
      var i = parseInt(add_id)+1;
      var newrow = '<div class="form-group" id="newr'+i+'"><label for="Upload">File '+i+':</label><input type="file" class="form-control" id="image'+i+'" name="image[]"></div><div class="form-group" id="deleterow'+i+'"><button type="button" class="btn btn-danger btn-sm" onclick="delRow('+i+')">Delete</button></div>';



    function delRow(i){


Step 3:-
Make sure that you have added enctype=”multipart/form-data” in the form tag and the [] in the name attribute of the file which is considered as the array of files.
Step 4:- Open the browser and enter the URL http://localhost/index.php and you can see the image as shown below.

From the above image, you can see that I have created multiple fields with a delete button so that I can add the file as much as I can and also delete it if necessary. You can hit the add file button to create multiple fields.

Creation of multiple fields using jquery

  • In index.php, I have added a hidden input field with zero value and a button element with id attribute and an extra div element to show the newly created field.
  • In the javascript part, I have used the button id attribute using the click function of jquery and increment the hidden value by 1 each time when it is clicked.
  • Also you can see that a remove() function of jquery is used to delete the newly created fields.

Step 4:- Now create an action file upload.php and add the code as shown below




	$filename = $_FILES['image']['name'];

	/*echo '<pre>';

	foreach ($filename as $key => $value) {
		// code...
         $target = 'uploads/'.basename($_FILES['image']['name'][$key]);
         move_uploaded_file($_FILES['image']['tmp_name'][$key], $target);

         echo '<script>';
         echo "alert('Files are uploaded successfully.')";
         echo '</script>';
         echo "<script type='text/javascript'>";
		 echo "window.location='index.php'";
		 echo "</script>";

Explanation of the above code

  • Now, we will receive the files with the help of PHP superglobal variable $_FILES as shown below
  • Now, we will use the foreach loop to count the files one by one.
  • Inside the loop, we will set a destination or storage location where the files will be stored as shown below
  • Finally we will move the uploaded files in the destination using the move_uploaded_file() function as shown below.

Note*:- basename() is used to get the filename from the path of the file.
