I am reading "PHP Programming with MySQL" by Don Goesselin. It seems like a good read but...
Except it does not discuss parsing input from an HTML page to a PHP document.
This what I have written for the HTML page to submit the info:
And this the PHP that is suppose to process the info:
So what am I doing wrong here?
Edit: Also as the title suggests, are there any debuggers out there for PHP like there are for JAVA?
Except it does not discuss parsing input from an HTML page to a PHP document.
This what I have written for the HTML page to submit the info:
<html>
<head><title>BMI</title></head>
<body>
<form action="BMI.php" method="get">
<form>
<br><b> BMI calculator: enter your weight and height</b></br>
<br>Weight in kilograms:
<input type="number" size="3" maxlength="3" name="weight"></br>
<br>Height in metters:
<input type="number" size="3" maxlength="3" name="height"></br>
<br> <input type="submit" value="submit"></br>
</form>
</body>
</html>
And this the PHP that is suppose to process the info:
<HTML>
<HEAD><TITLE> Receiving W and H </TITLE> </HEAD>
<BODY>
<?PHP
$BMI = $_get(weight) / ($_get(height) * $_get(height));
print "<BR> Your Body Mass Index is: $BMI";
?>
</BODY>
</HTML>
So what am I doing wrong here?

Also, its been a while.... are HTML forms referenced by ID? or name?
I think I remember it being element by ID......
Another things I see is $_get(weight). $_GET is an array, so you should use [] instead. Also, you give it strings for your inputs.
Try $BMI = $_GET / ($_GET * $_GET);
By name.
And for that second question I am taking it that there is no such thing as a debugger for PHP?
You lost me there but I am assuming you are suggesting changing the type from "number" (it now reads "int") to "string"?
Oh, sorry. I meant you use strings for the $_GET array's keys. So I would type $_GET. I should have been more clear.
The inputs tags should have type="text".
