   • Publish the page/post to complete.

Method 2: Using Custom Code

1. Add code to functions.php:

   • Open your theme's functions.php file and add the following code:

   function custom_image_upload_form() {
       if (isset($_POST['submit'])) {
           $uploaded_files = $_FILES['upload_images'];
           $upload_dir = wp_upload_dir();
   
           foreach ($uploaded_files['name'] as $key => $value) {
               if ($uploaded_files['name'][$key]) {
                   $file = array(
                       'name'     => $uploaded_files['name'][$key],
                       'type'     => $uploaded_files['type'][$key],
                       'tmp_name' => $uploaded_files['tmp_name'][$key],
                       'error'    => $uploaded_files['error'][$key],
                       'size'     => $uploaded_files['size'][$key],
                   );
   
                   require_once(ABSPATH . 'wp-admin/includes/file.php');
                   $uploaded_file = wp_handle_upload($file, array('test_form' => false));
   
                   if ($uploaded_file && !isset($uploaded_file['error'])) {
                       echo "Image uploaded: " . $uploaded_file['url'] . "<br>";
                   } else {
                       echo "Upload error: " . $uploaded_file['error'] . "<br>";
                   }
               }
           }
       }
   
       echo '
           <form method="post" enctype="multipart/form-data">
               <input type="file" name="upload_images[]" multiple>
               <input type="submit" name="submit" value="Upload Images">
           </form>
       ';
   }
   
   add_shortcode('image_upload_form', 'custom_image_upload_form');
   

2. Insert the [image_upload_form] shortcode into a page or post:

   • Now you can add [image_upload_form] to any page/post where you want the image upload form to appear.

System Requirements:

• WordPress version 5.0 or above
• PHP version 7.0 or higher
• For the plugin: WPForms version 1.6.0 or above

How to install the WPForms plugin:

• Go to Plugins > Add New in WordPress, search for “WPForms,” and click “Install Now.” Once installed, click “Activate.”

Tips:

• Ensure you set a file upload size limit to avoid filling up your storage.
• Test your form on multiple browsers to ensure compatibility.
