$_Post not retrieving data while $_Get is

Question

I am new to Php so i basically dont know much just started studying from a book php and mysql doing the same as the book said but my code doesnt fetch the data if i use Post method but does work if i use Get method. the book has used post so kind of confused here :/ this is the html part:

<!DOCTYPE html>

<html lang="en">

<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<form action="processorder.php" method="POST">
    <table border="0">
        <tr bgcolor="#cccccc">
            <td width="150">Item</td>
            <td width="15">Quantity</td>
        </tr>
        <tr>
            <td>Tires</td>
            <td align="center"><input type="text" name="tireqty" size="3"
                                      maxlength="3" /></td>
        </tr>
        <tr>
            <td>Oil</td>
            <td align="center"><input type="text" name="oilqty" size="3"
                                      maxlength="3" /></td>
        </tr>
        <tr>
            <td>Spark Plugs</td>
            <td align="center"><input type="text" name="sparkqty" size="3"
                                      maxlength="3" /></td>
        </tr>
        <tr>
            <td colspan="2" align="center"><input type="submit" value="SUBMIT ORDER" /></td>
        </tr>
    </table>
</form>
</body>
</html>

And the php code is this

<html>
<?php
// create short variable names
$tireqty = $_POST['tireqty'];
$oilqty = $_POST['oilqty'];
$sparkqty = $_POST['sparkqty'];
?>
<head>
    <title>Bob’s Auto Parts - Order Results</title>
</head>
<body>
<h1>Bob’s Auto Parts</h1>
<h2>Order Results</h2>

<?php
echo "<p>Order processed at " .date('H:i, jS F Y')."</p>";
echo '<p>Your order is as follows: </p>';
echo $tireqty.' tires<br />';
echo $oilqty.' bottles of oil<br />';
echo $sparkqty.' spark plugs<br />';
?>

</body>
</html>

If i use the _GEt method the values of this variables are shown but with post method nothing is retrieved.

Are you reading from `$_POST` only when "submitting" the form? — Flosculus, Dec 24 '15 at 10:12
https://www.evernote.com/l/AAPMDVwk0mhG6pIMQQ9-8eEG636S-MoqWmc — I can't reproduce the problem. Best guess is that you are using a cached version of the HTML where the form still says GET. — Quentin, Dec 24 '15 at 10:14

tested your code and is working fine. Clear browser cache and check again.. — Sameer K, Dec 24 '15 at 10:17

@SAMEERK I AM USING PHPSTORM CAN YOU tell me on which did you run it on ? — Daniyal Ahmed, Dec 24 '15 at 10:26
If the above DOCTYPE doesn't work. Then use this ` ` Let me know what happened. — Nana Partykar, Dec 24 '15 at 10:32
@NanaPartykar THE FIrst one didnt work and the second URI is not registered — Daniyal Ahmed, Dec 24 '15 at 10:35
Ok. Then, There is issue. Wait. I'm giving you link. Just follow it step by step. — Nana Partykar, Dec 24 '15 at 10:44

Hi Mr @Barmar : See I don't have any idea about it. I asked him about IIS related thing. He said *i do remember configuring iis for phpstorm*. So, just for helping I gave this link to him. — Nana Partykar, Dec 24 '15 at 10:50
@NanaPartykar its already turned on but just one question which verb should i write in deny verb ? — Daniyal Ahmed, Dec 24 '15 at 10:57
Hi @DaniyalAhmed : I don't have much idea about this. But, they have written TRACE. So, you can try TRACE. But not sure. *Sorry.* — Nana Partykar, Dec 24 '15 at 10:59
@NanaPartykar i just have my final project in a month and i've been on this since a week :/ the trace doesnt work though :/ Thanks though :D — Daniyal Ahmed, Dec 24 '15 at 11:05

If you used form attribute method is POST definitely you will get the data using $_POST in the php file might be there is caching issue or instead of $_POST you can use it $_REQUEST but i would suggest you clear your cache first then try again with $_POST

Also I do not think this is a code issue, rather it is a configuration issue with either apache or php. and you should only go with $_POST is more secure!

Thanks

THE request and get both methods are working even clearing the cache didnt help for post – Daniyal Ahmed Dec 24 '15 at 10:43
Have you check "post_max_size" in the php.ini file ? – Vinod Patidar Dec 24 '15 at 10:47
Are you getting any errors while use $_POST ? – Vinod Patidar Dec 24 '15 at 10:49
Also try to exclude all js if you're using on the page. – Vinod Patidar Dec 24 '15 at 10:50
NO JS and no error just null value – Daniyal Ahmed Dec 24 '15 at 11:00
ini_set('display_errors', true); error_reporting(E_ALL); Please put these above lines there and check any error showing and let me know – Vinod Patidar Dec 24 '15 at 11:01
'Order processed at 16:07, 24th December 2015 Your order is as follows: tires bottles of oil spark plugs Items ordered: 0 Subtotal: $0.00 Total including tax: $0.00 The output no errors – Daniyal Ahmed Dec 24 '15 at 11:08
Unfortunately, i think Apache or PHP was not installed properly. take your projects and DB backup and uninstall and install it again! Good luck if you if you agree with answer make it right answer. thanks – Vinod Patidar Dec 24 '15 at 11:13
i have php storms php was already installed and apache too – Daniyal Ahmed Dec 24 '15 at 11:22

Well, Are you sure post not working, Please check post method contains data or not by using.

var_dump($_POST); and var_dump($_REQUEST);

if you don't found anything in post then it will be in request if it is then your request is submitting by get method.

if it display an array with array entered in post then your post method is working and problem is with your file and your file was unable to open due to some security problem/incorrect path or may be due to file permission. So check and let me know.

<?php
    if (isset($_POST['tireqty'])) {
        $tireqty = $_POST['tireqty'];
        $oilqty = $_POST['oilqty'];
        $sparkqty = $_POST['sparkqty'];
    }
    ?>

Please do not post code without any supporting text. Explain what this snippet does and how it would help the OP solve their problem. Help others to understand. – APC Dec 25 '15 at 12:27
While this code may answer the question, it is better to explain what it does and add some references to it. – Hamid Pourjam Dec 25 '15 at 13:05
