Help me make my code and page pretty!!!!

gathos · February 19, 2008

ok so here is the page i need help with

http://www.typh.ca/phpcalctest.php now what i need is to HIDE (or something) the sentence that contains the estimate until the user clicks submit.

i have one condition - it has to be simple (cause i'm an idiot.)

any ways heres my code:

<html>
<head>
<title>Price calculator</title>
</head>
<body>

<?php
$length = $_POST["length"];
$height = $_POST["height"];
$price = $_POST["price"];
$total = $_POST["total"];
?>

<p><img src="Phil/images/b_spiderman.gif" height="100"></p>
<form method="post" action="<?php echo $PHP_SELF;?>">

  <p>Length:
    <input type="text" name="length" id="length">
    <br>
    Height:
    <input type="text" name="height" id="height">
  </p>
  <p>
    <input type="submit" value="submit" name="submit">
  </p>
</form>

<?
// set the PRICE to the square footage cost of the inserts
$price = 0.25;

$total = $length * $height * $price;
echo "Your inserts are an estimated cost of $ $total";
?> 
</body>

Please help me, i'm hitting a brick wall and my brain is starting to detach.

Or you could be more specific and use...

<html>
<head>
<title>Price calculator</title>
</head>
<body>

<?php
$length = $_POST["length"];
$height = $_POST["height"];
$price = $_POST["price"];
$total = $_POST["total"];
?>

<p><img src="Phil/images/b_spiderman.gif" height="100"></p>
<form method="post" action="<?php echo $PHP_SELF;?>">

  <p>Length:
    <input type="text" name="length" id="length">
    <br>
    Height:
    <input type="text" name="height" id="height">
  </p>
  <p>
    <input type="submit" value="submit" name="submit">
  </p>
</form>

<?php
if(strip_tags($_POST['length']) && strip_tags($_POST['height']) && strip_tags($_POST['submit'])){
//NOTE THAT $_POST['length'] OR $_POST['height'] IS FROM THE INPUT FIELDS NAME 

//if u use cooldudes and ur using more than one form on a page
//you'll run into problems

// set the PRICE to the square footage cost of the inserts
$price = 0.25;

$total = $length * $height * $price;
echo "Your inserts are an estimated cost of $ $total";
}
?> 
</body>

THANK YOU SO MUCH!!!! now i can keep my job pretending i know what i'm doing !!!!! lol

thanks again

cooldude832 · February 19, 2008

how does verifying if strip tags works on variables do anything in your case???

Also fyi you aren't doing anything productive with those strip_tags

also

$PHP_SELF isn't good to use because its a registered global of $_SERVER['PHP_SELF']

sorry I'm a super noob, I have no idea what to use instead if i remove the fist section of php code:

<?php
$length = $_POST["length"];
$height = $_POST["height"];
$price = $_POST["price"];
$total = $_POST["total"];
?>

the calculator stops working, i'm not sure what else to use instead.

as for the global variable again i have no idea what to use instead.

I basically thought myself a freaking genious to stumble upon this. (and i demostrate of how much of a genious by my spelling)

helps if we see your whole script.

Fyi if you have a job in php maybe you should consider taking classes

thanks for taking time out of your day to help

here is the code - it neded sixteenth added so i did, but it doesn't work.

<html>
<head>
<title>Price calculator</title>
</head>
<body>


<?php
$width = $_POST["width"];
$width = $_POST["width16"];
$height = $_POST["height"];
$height16 = $_POST["height16"];
$price = "0.25";
$totalheight = $_POST["totalheight"];
$totalwidth = $_POST["totalwidth"];
$total = $_POST["total"];
?>

<p><img src="Phil/images/b_spiderman.gif" height="100"></p>
<form method="post"> 
         <p>
           <input type="text" name="height">
           <select name="height16" id="height16">
	   <option value="0">Choose sixteenth</option>
             <option value="0.0625">1/16</option>
             <option value="0.125">1/8</option>
             <option value="0.1875">3/16</option>
             <option value="0.250">1/4</option>
             <option value="0.3125">5/16</option>
             <option value="0.375">3/8</option>
             <option value="0.4375">7/16</option>
             <option value="0.500">1/2</option>
             <option value="0.5625">9/16</option>
             <option value="0.625">5/8</option>
             <option value="0.6875">11/16</option>
             <option value="0.750">3/4</option>
             <option value="0.8125">13/16</option>
             <option value="0.875">7/8</option>
             <option value="0.9375">15/16</option>
           </select>
           <br>
             <input type="text" name="width">
             <select name="width16" id="width16">
		 <option value="0">Choose sixteenth</option>
             <option value="0.0625">1/16</option>
             <option value="0.125">1/8</option>
             <option value="0.1875">3/16</option>
             <option value="0.250">1/4</option>
             <option value="0.3125">5/16</option>
             <option value="0.375">3/8</option>
             <option value="0.4375">7/16</option>
             <option value="0.500">1/2</option>
             <option value="0.5625">9/16</option>
             <option value="0.625">5/8</option>
             <option value="0.6875">11/16</option>
             <option value="0.750">3/4</option>
             <option value="0.8125">13/16</option>
             <option value="0.875">7/8</option>
             <option value="0.9375">15/16</option>
             </select>
         </p>
         <p><br>
             <input type="submit" name="submit" value="Calculate"> 
         </p>
</form>

<?
if(!empty($_POST)){

// set the PRICE to the square footage cost of the inserts
$price = 0.25;
$totalwidth = $width + $width16;
$totallength = $length + $length16;
$total = $totalwidth * $totalheight * $price;
echo "Your inserts are an estimated cost of $ $total";
}
?> 
</body>

so i get a result of $0 when it echo's price

and FYI i would take classes but i can't because i work 2 jobs and help my wife take care of my baby, since she's to sick to look after him all the time, and i can't afford to spend any money on classes.

but you didn't know that.

and THIS isn't my job i was joking, i work on stained glass, i told my boss i can do html - hell everyone does html, but he want's it all. asp java php mysql css ecommerce, and is willing to pay for me to learn on my own but not willing to pay for classes. so thank you I really apreaciate your time, but if you feel that I should go to classes instead of asking for help, fine don't answer.

I know they fixed your code, but I hope you saw the errors.

You were adding/multipling variables that didn't exist.
