I don't have a ton of php experience but I am trying to have math problem echoed in the same browswer screen upon submit. Problem is when I submit nothing appears it just looks like i refreshed the page. I've tried moving the php coding into a seperate .php file so the form can call it. the same thing happens though. Do I need to be connected to Wamp so php can work? I'm not calling mysql or anything.

Quick diagnosis and a safe fix.

Since confirmed reinstalling WAMP fixed the server-side problem, the remaining issue in the posted snippets was malformed HTML that prevented the browser from sending form values. Key markup problems to watch for: a textarea with a value attribute and a self-closing slash (textarea must contain its value between tags), a checkbox input with a missing quote in the name attribute (this breaks parsing), and inconsistent input naming (pictures vs picture) which makes the PHP variables unpredictable. , , and were right to point at environment, superglobals and error checking — once the server runs, fix the markup and validate inputs.

A minimal, corrected form and a robust PHP processor (use $_POST, check isset() and cast to integers) will make the calculation reliable. Example form (fixed attributes and consistent names):

<form method="post" action="pricing.php">
  <textarea name="pages" rows="1" cols="5"></textarea>

  Pictures:
  <label><input type="radio" name="pictures" value="50">50</label>
  <label><input type="radio" name="pictures" value="25" checked>25</label>
  <label><input type="radio" name="pictures" value="0">0</label>

  <label><input type="checkbox" name="extras[]" value="50">Picture pack</label>
  <label><input type="checkbox" name="extras[]" value="50">Literature</label>
  <label><input type="checkbox" name="contact" value="100">Contact Form</label>

  <input type="submit" value="Calculate">
</form>

Example processing strategy: read posted values with isset() / intval() (or (int)), treat checkbox groups as arrays, sum carefully and provide defaults of 0 for missing fields. If results remain empty, enable error reporting or check server logs (environment issues are silent otherwise). This approach fixes parsing errors, avoids undefined-variable notices, and yields predictable totals.

The PHP file must be in the root folder ("C:\Program Files\wamp\www\" maybe?) and WAMP (Apache server, to be exact) must be on. Then run it with "http://localhost/math_file.php" in your browser.

If this doesn't work, paste your code here within [.code][./code] tags. It might have something to do with your source code.

if you're using wamp server just enable display errors in php settings in order for you to be prompted with an error message, so as for you to determine the error.

yep, try to use $_POST instead of $_REQUEST

kar123 0 Newbie Poster · Answer 3 · 2010-09-09T13:12:19+00:00

Yes, I also agree with britoniah and flamer here. Hope posting $_POST can solve your problem immediately. Please try this and let us know what happened.

It si good to RTM,
that being said it is not recommended to use request as it will pick contents of $_POST, $_GET, $_COOKIE. So be explicit to avoid problems. So just use $_POST/GET
Post being recommended! See Manual

That's a good point there. Thanks for the further explanation :)

MooGeek 16 Posting Whiz · Answer 8 · 2010-09-10T05:29:22+00:00

wait, its not the WAMP maybe, (or if you still have doubts why don't you reinstall it?)
did you tried changing $_REQUEST to $_POST??

Stefano Mtangoo 455 Senior Poster · Answer 9 · 2010-09-10T10:26:29+00:00

If you want to know if it is server issue or not try to make PHP file and access it on Url and in the PHP file put just the simple code below

<?php phpinfo();?>

RazorRamon 0 Junior Poster in Training · Answer 10 · 2010-09-10T19:11:44+00:00

It was wamp. I had deleted some of the files that were in there. I uninstalled and reinstalled the entire wamp program and php worked when i tested it in there. Thanks everybody for your help!!!
