how to submit a form to itself by using post method in php?

Question

I am trying to submit a form by post method on itself. but every time the form submits and page is refreshed. it doesn't show values.

<?php echo $_POST['fname']; ?>
<form method="POST" action='#.php'>
<input type="text" name="fname" id="fname" />
<button id="check" name="check" type="submit">GO</button>
</form>

What's the point, i am missing?

One assumes your filename is not `#.php`. – Progrock Sep 05 '16 at 06:36 — Progrock, Sep 05 '16 at 06:36

Try this :

<?php echo $_POST['fname']; ?>
<form method="POST" action=""> <!-- not single quote -->
<input type="text" name="fname" id="fname" />
<input type="submit" name="value" >
</form>

@AmanBarnwal, I am getting the whatever I entered in the text box. Can you please give me your full code? On which browser you are executing the script? – KavitaP Sep 05 '16 at 06:58

@Aman Barnwal replace the action='#.php' to action = "" – FullStack Sep 05 '16 at 07:08
tried that but still didn't work @dass – Aman Barnwal Sep 05 '16 at 07:13
@AmanBarnwal, can you please try to print only and let me know, it prints "test" or not? Also, run the above code in another browser. Make sure PHP installed on your system. – KavitaP Sep 05 '16 at 07:16
it worked, thanks! – Aman Barnwal Sep 05 '16 at 07:24
So, the above code is working now? – KavitaP Sep 05 '16 at 07:46

Try this...

<?php

if ($_SERVER['REQUEST_METHOD'] == 'POST') {

echo "<pre>";
print_r($_POST);

} ?>

<form name="test" action="" method="post"><input type="text" name="firstName" /><input type="submit" name="Submit" /></form>

I would recommend to write more cleaner way. like this:

<?php 
if(isset($_POST['fname']) && !empty($_POST['fname']) ){
 echo $_POST['fname'];
}
?>
<form method="POST" action=""> <!-- not single quote -->
<input type="text" name="fname" id="fname" />
<input type="submit" name="value" >
</form>
