How To Make Uploader Form in WordPress Without Using a Plugin

Hello, fellow coders! Asif Khan here, and today, I’ll guide you through the process of uploading custom files in WordPress without relying on a plugin. Let’s dive into the step-by-step procedure:

Step 1: Access Your Hostinger Dashboard

  1. Log in to your Hostinger dashboard.
  2. Navigate to the File Manager section.

Step 2: Explore the File Structure

  1. Once in File Manager, go to public_html.
  2. Click on wp-content.

Step 3: Choose Your Theme

  1. Within wp-content, locate the themes directory.
  2. Choose the currently activated theme; in my case, I’m using the Astra theme.

Step 4: Edit the functions.php File

  1. Double-click on the Astra theme to access its files.
  2. Open the functions.php file.

Step 5: Insert the Custom Code

Add the following code to the functions.php file:

// Add this code to functions.php

// Create the database table
function create_form_table() {
    global $wpdb;
    $table_name = $wpdb->prefix . 'applicant_data';

    $charset_collate = $wpdb->get_charset_collate();

    $sql = "CREATE TABLE IF NOT EXISTS $table_name (
        id mediumint(9) NOT NULL AUTO_INCREMENT,
        full_name varchar(255) NOT NULL,
        address varchar(255) NOT NULL,
        resume_path varchar(255) NOT NULL,
        PRIMARY KEY  (id)
    ) $charset_collate;";

    require_once(ABSPATH . 'wp-admin/includes/upgrade.php');

// Handle form submission
function handle_form_submission() {
    if (isset($_POST['submit_form'])) {
        global $wpdb;

        $table_name = $wpdb->prefix . 'applicant_data';

        $full_name = sanitize_text_field($_POST['full_name']);
        $address = sanitize_text_field($_POST['address']);

        // Handle File Upload
        if (isset($_FILES['resume'])) {
            $uploaded_file = $_FILES['resume'];

            $upload_dir = wp_upload_dir();
            $upload_path = $upload_dir['path'];
            $resume_path = $upload_path . '/' . $uploaded_file['name'];

            move_uploaded_file($uploaded_file['tmp_name'], $resume_path);

            // Save to Database
                    'full_name'   => $full_name,
                    'address'     => $address,
                    'resume_path' => $resume_path,

            // Optionally, you can redirect the user after form submission

// Initialize the table and form submission
add_action('init', 'create_form_table');
add_action('init', 'handle_form_submission');

// functions.php

function display_applicant_data() {
    global $wpdb;

    $table_name = $wpdb->prefix . 'applicant_data';
    $data = $wpdb->get_results("SELECT * FROM $table_name");

    if ($data) {
        echo '<table>';
        echo '<tr><th>ID</th><th>Full Name</th><th>Address</th><th>Resume</th></tr>';
        foreach ($data as $row) {
            echo '<tr>';
            echo '<td>' . $row->id . '</td>';
            echo '<td>' . $row->full_name . '</td>';
            echo '<td>' . $row->address . '</td>';
            echo '<td><a href="' . $row->resume_path . '" target="_blank" download>Download Resume</a></td>';
            echo '</tr>';
        echo '</table>';
    } else {
        echo 'No data found.';
add_shortcode('display_applicant_data', 'display_applicant_data');

Remember to save the file after pasting the code.

Step 6: Create a New Page in WordPress

  1. Go to the WordPress admin area.
  2. Create a new page where users will submit the form.

Step 7: Add the Submission Form HTML

Paste the HTML code for the submission form:

<!-- HTML Form -->
    form {
        max-width: 400px;
        margin: 0 auto;
        background-color: #f9f9f9;
        padding: 20px;
        border-radius: 10px;
        box-shadow: 0 0 20px rgba(0, 0, 0, 0.1);

    label {
        display: block;
        margin-bottom: 8px;
        color: #333;
        font-weight: bold;

    input[type="file"] {
        width: 100%;
        padding: 12px;
        margin-bottom: 20px;
        border: 1px solid #ccc;
        border-radius: 6px;
        box-sizing: border-box;
        font-size: 14px;

    input[type="submit"] {
        background-color: #4caf50;
        color: #fff;
        padding: 15px 20px;
        border: none;
        border-radius: 8px;
        cursor: pointer;
        font-size: 16px;
        transition: background-color 0.3s;

    input[type="submit"]:hover {
        background-color: #45a049;

<form method="post" action="" enctype="multipart/form-data">
    <label for="full_name">Full Name:</label>
    <input type="text" name="full_name" required>

    <label for="address">Address:</label>
    <input type="text" name="address" required>

    <label for="resume">Resume Upload (PDF, DOC, DOCX):</label>
    <input type="file" name="resume" accept=".pdf, .doc, .docx" required>

    <input type="submit" name="submit_form" value="Submit">

This will render a visually appealing form for users to submit.

Step 8: Create a “Thank You” Page

  1. Create another page for users to be redirected to after submission, commonly known as the “Thank You” page.

Step 9: View Submission Data

  1. Create a new page and use the shortcode [display_applicant_data] to display all submission data.

And there you have it! A professional and user-friendly method to upload files in WordPress without relying on plugins. Happy coding!
