HTML Form Action

In HTML, the action attribute is used in the <form> element to specify the URL or the location where the form data should be submitted when the form is submitted by the user. It determines the server-side script or program that will process the form data.

Here’s an example of how to use the action attribute in an HTML form:

<form action="submit-form.php" method="POST">
  <!-- form fields and inputs -->
  <input type="text" name="name">
  <input type="email" name="email">
  <button type="submit">Submit</button>
</form>

In the above example, the action attribute is set to "submit-form.php". This means that when the user submits the form, the form data will be sent to the server-side script or program located at submit-form.php for processing.

The action attribute can take various values:

• A relative URL: For example, "submit-form.php" or "process-form.php". This is commonly used when the server-side script is located in the same directory as the HTML file.
• An absolute URL: For example, "https://www.example.com/submit-form.php". This is used when the server-side script is located on a different server or domain.
• A special value: "#", "javascript:void(0)", or "" (empty string). These values are sometimes used to indicate that the form should be handled using JavaScript without submitting to a server.

It’s important to note that the form action attribute works in conjunction with the method attribute, which specifies the HTTP method to be used when submitting the form (e.g., GET or POST).

When the user submits the form, the browser sends the form data to the specified action URL using the specified HTTP method. The server-side script or program can then process the form data and perform the necessary actions, such as storing the data in a database, sending an email, or generating a response.

It’s recommended to validate and sanitize the form data on the server-side to ensure data integrity and security.
