HTML Forms

Introduction to HTML Forms

HTML Forms are essential for building interactive and dynamic websites. They enable users to input and submit data to a server, making functionalities like registration, login, and feedback possible.

In this tutorial, we will explore HTML form attributes, elements, and techniques with practical examples to help you create efficient and user-friendly forms.

HTML Form Attributes

HTML forms come with various attributes that define their behavior:

• action: Specifies the URL where the form data will be sent after submission.
• method: Defines the HTTP method (GET or POST) to be used when submitting the form.
• enctype: Specifies how form data should be encoded when submitting files.
• target: Specifies where to display the response (e.g., in the same tab, new tab, etc.).

Example: Basic HTML Form

Here’s a simple example of an HTML form:

<form action="/submit" method="post">
    <label for="name">Name:</label>
    <input type="text" id="name" name="name" required>

    <label for="email">Email:</label>
    <input type="email" id="email" name="email" required>

    <input type="submit" value="Submit">
</form>
        

HTML Form Elements

HTML provides various elements to create functional and interactive forms:

• <input>: Creates input fields for text, numbers, passwords, etc.
• <textarea>: Adds a multiline text input field.
• <select>: Creates dropdown menus.
• <label>: Defines labels for form elements, improving accessibility.
• <button>: Adds a clickable button.

Example: Contact Form

The following example demonstrates a contact form:

<form action="/contact" method="post">
    <label for="name">Name:</label>
    <input type="text" id="name" name="name" required>

    <label for="email">Email:</label>
    <input type="email" id="email" name="email" required>

    <label for="message">Message:</label>
    <textarea id="message" name="message" rows="5" cols="30" required></textarea>

    <input type="submit" value="Send">
</form>
