How to Send Form Data with Button Values in PHP?

Sending Form Data with Button Value

You're facing an issue with submitting the value of submit buttons in a form post. In your provided code, the button names are labeled as "submit" instead of the intended product names, which prevents the PHP script from retrieving the desired value.

Solution:

To resolve this issue, you'll need to assign unique names to the submit buttons and ensure that the PHP script expects the value in the correct variable name. Here's an updated code snippet:

Sending Page:

<html>
<form action="buy.php" method="post">
    <select name="name">
        <option>John</option>
        <option>Henry</option>
    <select>
    <input type="hidden" name="action" value="submit">
    <input type="submit" name="submit" value="Tea">
    <input type="submit" name="submit" value="Coffee">
</form>
</html>

Copy after login

Receiving Page (buy.php):

<?php
if (isset($_POST['action'])) {
    $name = $_POST['name'];
    $purchase = $_POST['submit'];
    // Database operations here
}
?>

Copy after login

In this updated code:

We've added a hidden input with the name "action" and the value "submit". This ensures that PHP can identify when a form submission has occurred.
The submit buttons now have unique names, allowing PHP to retrieve the correct value from the $_POST array.
In the receiving PHP script, we check for the existence of the "action" field to confirm the form submission.

By making these changes, you'll be able to successfully send the values of your submit buttons along with the other form data.
