HTML Input Type Hidden

The HTML input type "hidden" is used to create input fields that are not visible to users but can hold values that are submitted with a form.
Hidden input fields are commonly used to pass data between web pages or to store information that does not need to be displayed.
They offer a way to transmit data securely without exposing it to users.
Let's explore the attributes and examples of using the input type "hidden" in HTML to cover all scenarios.

1. Basic Hidden Input:

To create a basic hidden input field, use the input element with type="hidden":

<input type="hidden" name="secret_key" value="abc123">

2. Dynamic Value:

You can set the value of the hidden input field dynamically using JavaScript:

<script>
    document.getElementById('hidden_input').value = 'dynamic_value';
</script>

<input type="hidden" id="hidden_input" name="dynamic_value">

3. Security Considerations:

Hidden input fields should not be used to store sensitive information, as they can be manipulated by users or scripts.

<input type="hidden" name="user_id" value="123456">

4. Form Submission:

Hidden input fields are included in form submissions and can be accessed on the server-side:

<form action="/submit" method="post">
    <input type="hidden" name="form_id" value="123">
    <button type="submit">Submit</button>
</form>

5. Use Cases:

Hidden input fields are commonly used to store session tokens, CSRF tokens, or other authentication data.
They can be employed to pass information between different pages of a web application, such as user preferences or settings.
Hidden input fields can facilitate communication between client-side and server-side scripts without exposing sensitive data to users.
They offer a way to transmit additional metadata along with form submissions, such as tracking codes or referral information.

Conclusion:

The HTML input type "hidden" provides a way to store and transmit data securely between web pages. By understanding its various attributes and examples, you can effectively utilize hidden input fields to enhance the functionality and security of your web applications.

Exercise caution when using hidden input fields to ensure that sensitive information is not exposed to users or vulnerable to manipulation. With proper implementation, hidden input fields can serve as valuable tools for managing data and enhancing the user experience of your web applications.
