Question

I have a input field as follows:

<input type="text" name="subject" id="subject" value="Car Loan">

I would like to get the input fields value Car Loan and assign it to a session. How do I do this using PHP or jQuery?

Answer 1

Use PHP’s $_POST or $_GET superglobals to retrieve the value of the input tag via the name of the HTML tag.

For Example, change the method in your form and then echo out the value by the name of the input:

Using $_GET method:

<form name="form" action="" method="get">
  <input type="text" name="subject" id="subject" value="Car Loan">
</form>

To show the value:

<?php echo $_GET['subject']; ?>

Using $_POST method:

<form name="form" action="" method="post">
  <input type="text" name="subject" id="subject" value="Car Loan">
</form>

To show the value:

<?php echo $_POST['subject']; ?>
