When writing web applications using PHP, we often need to submit form data and jump to another page. This article will introduce how to use PHP to submit form data and jump to the page.

First, we need to create an HTML form to collect user data. Here is a simple example:

<form action="process.php" method="post">
  <label for="name">Name:</label>
  <input type="text" id="name" name="name"><br>
  <label for="email">Email:</label>
  <input type="email" id="email" name="email"><br>
  <input type="submit" value="Submit">
</form>

Copy after login

In the form, we specify an action called "process.php" and use the "post" method to submit the form data. When the user clicks the submit button, the form will send data to process.php.

Next, we need to create the process.php file to process the submitted form data. In this file, we can use the $_POST array to retrieve the submitted data. Here is a simple example:

<?php
  $name = $_POST[&#39;name&#39;];
  $email = $_POST[&#39;email&#39;];
  // do something with $name and $email
  header("Location: thank-you.php"); // redirect to thank-you page
?>

Copy after login

In the above example, we use the $_POST array to get the data named "name" and "email". We can then do whatever we want with this data. Finally, we use the header() function to redirect the user to another page called "thank-you.php". Note that this code should be called before any other output in the process.php file. Otherwise, the header() function will not work properly.

In the thank-you.php file we can display a thank you message or any other message to the user. The following is a simple example:

<!DOCTYPE html>
<html>
<head>
  <title>Thank You</title>
</head>
<body>
  <h1>Thank You</h1>
  <p>Thank you for submitting your information, <?php echo $_POST[&#39;name&#39;]; ?>!</p>
</body>
</html>

Copy after login

In the above example, we use the "name" data in the $_POST array to display the thank you message to the user. Please note that we use the syntax to insert user-entered data into the HTML.

In short, it is very simple to submit form data and jump to another page using PHP. We just need to use the $_POST array to retrieve the data and then use the header() function to redirect the user to another page. I wish you a pleasant experience!
