Php Help Needed Urgent

thewizard_it

Hello
I have installed php version 4.3.2, I have tried code I learned which does not require variables who supose to read from forms to place an if (isset($variable)){.....................} But I keep getting erors if I exclude the If(isset($variable)) statement so I am obliged to include it which requires a lot of changuing the code and logic of the program, also by using the if(isset) I cannot use the header("location:file.php")
All the books I studied do not use the if(isset) statement , what must I do in order to avoid using the if(isset) statement
I need titles of php books teaching php4.3.2 and no other versions which contain differences

First off, you should know that by default, the register globals is off in version 4.3.2.

Because of this, you should refer to the variables being posted by a form by calling them from the $POST array like so:

IF(isset($_POST['variablename'])){
// do this if it exists
} else {
// do this if it doesn't
}

Secondly, having that step of checking to see if it is posted is good coding practice...

Thirdly, why look for any books, when the PHP Manual at www.php.net has everything you could possibly need or want to know, and they have a downloadable CHM file for you if you are a Windows user...

http://uk.php.net/manual/en/function.isset.php is always a good place to start.
