[RESOLVED] PHP Post not diplaying variables

Austio

Hey all, posting from a form that looks like this

<form action="processorder.php" method=post>
<table>
<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>
</table>
</form>

to processorder.php which looks like this

	<?php
		$str = $tireqty;
		echo "<p>Order Processed.";
		echo date("H:i, jS F");
		echo "<br>";

	echo "<p>Your order is as follows:";
	echo "<br>";
	echo $tireqty;
	echo "l";		
?>

The results come out like this

Order Processed.07:48, 26th January

Your order is as follows:
l

I know that the variables are being passed because when I use a GET they are displayed in the URL. I put the L as the last echo so that I know that it is executing all of the commands. Any help would be much appreciated. Thanks

As your form is method="post"
you need to read the value from an array called $POST

<?php
$str = $_POST['tireqty'];
echo "<p>Order Processed.";
echo date("H:i, jS F");
echo "<br>";

echo "<p>Your order is as follows:";
echo "<br>";
echo $str;
echo "l";
?>

Also I see no SUBMIT button

<form action="processorder.php" method="post">
<table>
<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><input type="submit" name="submit" value="Submit Order"></td>
<td></td>
</tr>
</table>
</form>

Thanks for the guidance. I made the change but don't see anything happening. I am using XAMPP if that helps at all.

Here is the full HTML for both files The first is the order form

<head>
<title>Sample 13.1</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />

</head>

<body>

<form action="processorder.php" method=post>
<table>
<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>

This is the processorder.php

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"?
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head> 	
	<title>bobs stuff</title>
</head>

<body>
	<h1>bobs</h1>
	<h2>order</h2>


<?php
	$str = $_POST['tireqty'];
	echo "<p>Order Processed.";
	echo date("H:i, jS F");
	echo "<br>";

	echo "<p>Your order is as follows:";
	echo "<br>";
	echo $str;
	echo "l";



?>
</body>


<!--
		echo $tireqty " tires<br>";
		echo $oilqty " bottles of oil<br>";
		echo $sparkqty " spark plugs<br>";
-->

</html>

The output is the same as the last one. Just as before, with a get statement it still posts the variable values in the URL

Strange.
I do not see where is the issue.

Try this for processorder.php

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"?
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>bobs stuff</title>
</head>
<body>
<h1>bobs</h1>
<h2>order</h2>
<?php

echo "<p>Order Processed. ";
echo date("H:i, jS F");
echo "</p>";

echo "<p>Your order is as follows:";
echo "<br>";
echo $_POST['tireqty']. " tires<br>";
echo $_POST['oilqty']. " bottles of oil<br>";
echo $_POST['sparkqty']. " spark plugs<br>";
echo "</p>";

?>
</body>
</html>

Well, i pasted your code in and tried it and got this response.

bobs
order

Order Processed. 10:17, 26th January

Your order is as follows:
tires
bottles of oil
spark plugs

I'm not sure if my php is just being anti-variable right now, i can't think of any reason why this wouldn't work.

I did the standard Xampp install too.

Not sure why you didn't see the correct value for $str for your example below, but note that that is the only variable you tried to output; the three echo statements at the bottom weren't wrapped in PHP tags and thus weren't evaluated by the PHP parser. Then again, it wouldn't matter if they were; there were parse errors (missing '.' concatenation operators) as well as undefined variables.

For more information on retrieving data sent in forms or in the query string, see this manual page: [man]variables.external[/man].

Hey all I was able to fix it by using a combination of printf and grabbing the array of posted data. Here is an argument that worked

printf ("Tire inventory: %d ", $_POST['tireqty']);

output was

Tire inventory: 1

I still can't figure out why the other part wasn't working, but maybe it's a good habit to get in by using printf all the time?
