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']; ?>
