[SOLVED] $_POST method help

[prakash]

I am little bit confused on using variable directly under $_POST to defile another POST variable

so how can extract the value of $test?

currently $test outputs blank value

 

<?php
$test1=$arrayvalue[$i];
$test=$_POST[$test1];
print $test;
?>

Where does $arrayvalue[$i] get set/come from?

$_POST is a defined superglobal containing all if set variables defined via the http method of POST.  You can't redefine them in your script you can extract their values 1 of two ways  A as an associtive array or B as an indexed array.  For most cases associtive is the proper method i.e $_POST['varkey'];

it gets value from the form which is in a array form

 

$arrayvalue=$_POST["myfield"];

the actual code is

 

<?php
$arrayvalue=$_POST["myfield"];
for ($i=0;$i<count($arrayvalue);$i++) {
$test1=$arrayvalue[$i];
$test=$_POST[$test1];
print $test;
}
?>

Ahh I see... You'll want to use

 

$test1 = $_POST[$arrayvalue[$i]]
