Undefined variable: POST - PHP and MySQL - php

Question

I've got a form like this:
<form name="htmlform" method="post" action="script/gen.php?postData">
<table width="450px">
</tr>
<tr>
<td valign="top">
<label for="customer">Customer:</label>
</td>
<td valign="top">
<input type="text" name="customer" maxlength="50" size="30">
</td>
</tr>
<tr>
<td valign="top"">
<label for="nol">Number of licences: </label>
</td>
<td valign="top">
<input type="text" name="nol" maxlength="50" size="30">
</td>
</tr>
<tr>
<td>
<form method="post" id="submit" action="script/gen.php">
<input type="button" onClick="getKey()"; value="Generate key"/>
</td>
</tr>
<div id="innhold">
<h4>Licence Key: </h>
</div>
<tr>
<td colspan="2" style="text-align:center">
<input type="submit" value="Submit">
</td>
</tr>
</table>
</form>
The codelines of interest is:
<input type="text" name="nol" maxlength="50" size="30">
and
<input type="text" name="customer" maxlength="50" size="30">
I try to write this information to a database like this:
function postData($key1) {
//just to check if the key is equal to the one thats posted to the user
//echo '<h5>From postData' . $key1 . '</h5>';
/*echo '<script type="text/javascript"> alert("The order has been submitted successfully");
location = "/Webpanel/index.html";
</script>';*/
$customerVar = $POST['customer'];
$nolVar = $POST['nol'];
mysql_connect("localhost","root","") or die(mysql_error());
mysql_select_db("licencedatabase");
$query_add = "INSERT INTO licence (`customer_name`,`licence_count`) VALUES ('$customerVar','$nolVar')";
$query_exec = mysql_query($query_add) or die(mysql_error());
mysql_close();
}
But I keep getting the error:
Undefined variable: POST
How can I accomplish this? Thanks in advance.

Answer 1

Its $_POST not $POST.
$customerVar = $_POST['customer'];
$nolVar = $_POST['nol'];

Answer 2

That's because it's called $_POST.

Answer 3

Try using $_POST instead of $POST

Answer 4

to access the superglobal POST use $_POST not $POST

Answer 5

All PHP superglobals (such as those for GET and POST) are prefixed with an underscore, so: $POST should be $_POST.
Have a look here for more information about the available superglobals in PHP:
http://php.net/manual/en/language.variables.superglobals.php

Answer 6

Try using $_POST instead of $POST
Check following example:
The predefined $_POST variable is used to collect values from a form sent with method="post".
Information sent from a form with the POST method is invisible to others and has no limits on the amount of information to send.
Example:
<form action="submitform.php" method="post">
Name: <input type="text" name="fname" />
Age: <input type="text" name="age" />
<input type="submit" />
</form>
When the user clicks the "Submit" button, the URL will look like this: http://localhost/submitform.php
The "submitform.php" file can now use the $_POST variable to collect form data (the names of the form fields will automatically be the keys in the $_POST array):
Welcome <?php echo $_POST["fname"]; ?>!<br />
You are <?php echo $_POST["age"]; ?> years old.
might you will understand clearly.
