[SOLVED] Basic form doesn't work.

[bskauge]

This was working some time ago about, but suddenly, without any changes, it didn't work anymore. This should be pretty basic, but I have no idea why this isn't working.

 

I have a form that asks for three numbers, and based on these numbers there will be a mathematical operation, and the answer will be given on the same page when you hit "beregn!" ("calculate" in english). The problem is that the answer doesn't show up, can anyone help me find out why? My host is running php version 5.2.0, this may have been upgraded, can't remember the last version.

 

The page is located here:

http://www.onlymalts.com/v2/tools/kalkistest.php

 

And this is some of the code:

 

<?php

$alc2 = 1.00;

?>

 

<div id="Layer1" style="position:absolute; left:210px; top:306px; width:472px; height:160px; z-index:7;">

  <span class="tekst">

  <form id="form2" name="form2" method="post" action="">

    <table width="100%" border="0" cellspacing="0" cellpadding="0">

    <tr>

      <td width="25%">Antall cl: </td>

      <td width="75%"><input name="cl" type="text" size="4" /></td>

    </tr>

    <tr>

      <td>Alkoholnivå i %:</td>

      <td><input name="alc" type="text" size="4" /></td>

    </tr>

    <tr>

      <td>Ønsket styrke i %:</td>

      <td><input name="styrke" type="text" size="4" /></td>

    </tr>

  </table>

  <br />

  <input type="image" src="/v2/bilder/beregn.jpg" />

  </form>

 

<?php

if ($cl == NULL)

echo ' ';

elseif ($styrke == 0)

echo 'Vann finner du i springen!';

elseif ($alc==0)

echo 'Vi skulle gjerne hjulpet deg med å gjøre vann om til whisky, vi jobber med saken. I mellomtiden anbefaler vi å ta turen innom polet.';

elseif ($cl==0)

echo 'Har du ikke whisky? Ikke en eneste dråpe?!';

elseif ($styrke>$alc)

echo 'Du må tilsette sterkere whisky for å få mer alkohol. Dette er en vannkalkulator!';

elseif ($alc>96)

echo 'Det er vel lite sannsynlig at du har fått tak i noe som er sterkere enn 96%.';

elseif ($styrke>0) {

$alc2 = &$styrke;

$resultat = $cl*($alc/$alc2)-$cl;

echo 'Du må tilsette ' .number_format($resultat,1).' cl vann i '.$cl.' cl med '.$alc.'% whisky for å få '.$alc2.'%.';

}

 

?>

</span>

<br /><br /><? include("../disclaimer.php") ?>

</div>

[r-it]

what is your form's action?

[Yesideez]

I can't see anywhere that you're using $_POST to get the values once the user clicks the submit button. Is this all of the script?

 

@r-it - the action is empty meaning itself

[Yesideez]

I just viewed the page - I can see it's not all of the script.

 

You need this somewhere...

$cl=$_POST['cl'];
$alc=$_POST['alc'];

Preferable in the php section at the top.

Use the code below in the top of the page

And do your calculation after these lines and do what do you want to do...

 

$cl = $_POST['cl'];
$alc = $_POST['alc'];
$styrke = $_POST['styrke'];

Oops I missed one - well done ashly

Thank you, ashly, that did the trick. I don't have the slightest clue why this worked before, it just did. Solved now.
