Sending data from a form using PHP

Question

I started with HTML yesterday and I'm trying to send some data from a page to another using PHP. I don't know if I am missing something but even the code I found on the Internet isn't working for me.

This is the code of my form:

<div class="login">
    <form name="myForm" action="post.php" method="POST">
      <div class="group1">
        <input type="text" name="fusername"><span class="bar"></span>
        <label>Username</label>
      </div>
      <div class="group2">
        <input type="text" name="fpassword"><span class="bar"></span> <span class="password"></span>
        <label>Password</label>
      </div>
      <button type="submit" class="button buttonBlue">Login</button>
    </form>
</div>

while this is the overall code of the post.php page:

<html>
<body>

Welcome <?php echo $_POST["fusername"]; ?><br>
You inserted as a password: <?php echo $_POST["fpassword"]; ?>

</body>
</html>

The only things I see after clicking the "Login" button are "Welcome" and "You inserted as a password".

I tried both get and post methods (with consistency) and I am still not able to see what I inserted in the forms.

I even tried to print a simple hello word, modifying the post.php page in this way:

<html>
<body>    

 <?php 
 Echo "Hello, World!";
 ?> 

</body>
</html>

but doing that I get a white page.

What am I actually missing or misunderstanding?

Many thanks.

Your method is `POST` and you are using `$_GET`. Change it to `$_POST`. — Virb, Aug 04 '17 at 08:44
Sorry, that was a typo, I tried both get and post with consistency but I still got the same problem. — giovandrea, Aug 04 '17 at 08:51
Check error by `var_dump($_POST)`. Tell us what you get an error? — Virb, Aug 04 '17 at 08:53
Just for kicks, get rid of this part in the `
tag and try again: `onsubmit="return validateForm()"` — Difster, Aug 04 '17 at 08:54
What is in the `validateForm()` function? It may return false for some reasons. — Mahbubul Islam, Aug 04 '17 at 09:00

As per your html both method are good might be it's just related with validate so please check without validate .. — Kuldeep Raj, Aug 04 '17 at 09:07

Maybe you don't have php on server side

write

<?php
phpinfo();

and run it

Change GET to POST. GET and POST are two different methods. You have to be consistent on how to use them in your forms. Personally, I prefer to always use POST unless there's a good reason to use get.

<html>
<body>

Welcome <?php echo $_POST["fusername"]; ?><br>
You inserted as a password: <?php echo $_POST["fpassword"]; ?>

</body>
</html>

Remove onsubmit="return validateForm()" from Form because your action of your form is already given so no need of validation then.

if it work then ok but if not then set action with full path like("http//www.example.com/post.php").

This is working fine as per your problem ..

You need to just change html with your input name .
