How to write this $_POST statement?

[ollie007]

$_POST[$type]

 

is that how i write the variable or do i need ".$type." ?

Assuming $type is defined somewhere, that should be fine.

You don't need the dollar sign. You are trying to access a $_POST value with the key of whatever is assigned to $type, which I'd imagine is nothing.

 

$_POST['type'];

no, $type is a string, so do i need the $ sign?

 

$type='name'

$type='address'

[gevans]

In which case yes, you need the dollar sign.

 

If $type is a string, and the string references one of the keys in $_POST it should work fine the way you originally posted.

 

<?php
//assuming name has been sent via post
$type = 'name';
$name = $_POST[$type];
echo $name;

 

If you are in a development environment and have errors on, you will see an error if the key does not exist.

ollie, I seriously think you need to find a good book. Coming here an asking multiple simple questions will take you forever to learn what's going on.

 

There's a good free book in my signature (Hudzilla) should get you started.
