Problem with Forms

dovetail · May 31, 2006

Hi, I'm unable to pass $_POST information between my form and my .php file. I'm using samples from the Tizag tutorial, but I can't get them to work. If I change the $_POSTs to $_GETs, I still get the same bad result at the bottom. I've also tried other html/.php samples from books, and no luck.

Here's my html...

-------------------------------------
ACTION.HTML
-------------------------------------
<html><body>
<h4>Tizag Art Supply Order Form</h4>
<form action="process.php" method="post">
<select name="item">
<option>Paint</option>
<option>Brushes</option>
<option>Erasers</option>
</select>
Quantity: <input name="quantity" type="text" />
<input type="submit" />
</form>
</body></html>

-------------------------------------

Here's my .php...
-------------------------------------
PROCESS.PHP
-------------------------------------

<html><body>
<?php
$quantity = $_POST['quantity'];
$item = $_POST['item'];
echo "You ordered ". $quantity . " " . $item . ".<br />";
echo "Thank you for ordering from Tizag Art Supplies!";
?>
</body></html>
-------------------------------------

Here's my output, when I fill out the HTML form and submit
-------------------------------------

"; echo "Thank you for ordering from Tizag Art Supplies!"; ?>

-------------------------------------

The correct output should have been:

You ordered 5 brushes.
Thank you for ordering from Tizag Art Supplies!

----------------------------------
I'm using WAMP5 1.6.3 with the following server configuration:

Apache version :
Apache/2.0.55 (Win32)

MySQL version :

Please help. Thanks!!! If it helps diagnose the problem, here are the results of phpinfo():

I can't see what the problem is as everything seems to be right but if you want to validate your data before accepting it you could have a slight problem with using two files. You can merge everything into one file like this:
[code]<?php
  if ($_POST['subsend']) {
    $quantity=$_POST['quantity'];
    $item=$_POST['item'];
  }
?>
<html><body>
<h4>Tizag Art Supply Order Form</h4>
<?php if ($quantity&&$item) { ?>
You ordered <?=$quantity?> <?=$item?><br />
Thank you for ordering from Tizag Art Supplies!
<?php } else { ?>
<form action="process.php" method="post">
<select name="item">
<option>Paint</option>
<option>Brushes</option>
<option>Erasers</option>
</select>
Quantity: <input name="quantity" type="text" />
<input type="submit" name="subsend" />
</form>
<?php } ?>
</body></html>[/code]Thats basically the idea - try that and see how it works.

Thank you for trying, Yesideez, though that didn't work either. I created a new file named allinone.php with your code and the the response was:

------
"; echo "Thank you for ordering from Tizag Art Supplies!"; ?>
------

Then I tried changing the formaction from process.php to allinone.php, so that it was calling itself. Here's what I received:

------
Tizag Art Supply Order Form
You ordered
Thank you for ordering from Tizag Art Supplies!
------

I'm stumped.

It looks like your webserver isn't processing PHP files correctly or you are invoking the script incorrectly.

How are you invoking the HTML file with the form?

Hi Ken, thanks for trying to help. If I understand your question correctly, I've got the form in .html and it invokes a separate .php file with <form action="process.php" method="post">. Both files are in the same directory. I'm able to execute other php files in the directory just fine, I just can't seem to get anything going with $_POST or $_GET. Ideas?

thanks,
mark

The reason I ask how you are invoking the "action.html" file is that if you are not using a URL like "http://localhost/action.html", then the PHP file will not be invoked correctly.

I saved your files on my laptop and invoked "action.html" two different ways:[ol type=\'1\'][*]I put in the URI "file:///C:/Program%20Files/xampp/htdocs/xxxxxx/phpfreaks/action.html" into the Firefox browser, filled in the form. When I clicked on the "Submit Query", I got the same output as you.[*]When I use the URL "http://localhost/kenrbnsn/phpfreaks/action.html", it works fine.[/ol]When you invoke the file the first way, the Apache webserver is not invoked, so PHP can not be processed.

Ken, I was hopeful this was the solution, but alas I reconfirmed that my html form triggers [a href=\"http://localhost/PHP/process.php\" target=\"_blank\"]http://localhost/PHP/process.php[/a], and I again reproduced that bad result.

Next, on a lark, I changed the form action to <form action="http://localhost/PHP/process.php" and got the same incorrect result.

Anything else I can try?

Thank you again for your help.

How did you invoke "action.html". That is the key.

Ken

dovetail · June 1, 2006

I invoked action.html via [a href=\"http://localhost/PHP/action.html\" target=\"_blank\"]http://localhost/PHP/action.html[/a]. It's in the same directory in which I'm able to successfully execute other non-GET non-POST functions.
Thanks,
Mark

(I know this is an old post, but I thought i'd respond anyway, just in case.)

If you double click to open any .html file , the address will read something like file:///C:/wamp/www/action.html\
If this is the case, the webserver will not be processing the files you are viewing, the browser will, and the browser can't process php.
What does it say in the address bar of your browser window? For php to be processed sucessfully by your wamp server, it should read http://localhost/PHP/action.html or something like that in the address bar.

reomove the action from the form tag all together, use [code]if(isset($_POST['submitbuttonname'])){[/code] instead
