Question

Is it possible to use a POST variable on the buffered script? The code is the following

<?php
header('Content-type: application/json');

$someVar= $_POST["var"];

ob_start();
require "someScript.php?var=" . $someVar; // instead of passing through GET, is there a way to use the $someVar directly?
$output = ob_get_clean();
echo $output;
?>

Note: I’ve already tried to access $someVar directly from someScript but without success. For that is why I’m asking. Thanks

EDIT: Possible someScript.php

<?php
    header('Content-type: application/json');
    require_once("BD.php");
    require_once("json/json_header.php");
    require_once("tools.php");
    require_once('class.phpmailer.php');

    $BD = new BDInfo(); 


    function encodeIDs($id1,$id2){

        // doesn't matter
    }

    $response = array("errorCode" => 0, "errorDesc" => "No Error");


    if(isset($someVar)){
        try{
            $link = mysqli_connect($BD->BDServer, $BD->BDUsername, $BD->BDPassword);

            if( !$link )
                throw new Exception( "..." );

            if( !mysqli_select_db($link, $BD->BDDatabase) )
                throw new Exception( "..." );

            $SQL="SELECT (...) us.VAR='" . $someVar . "';";

            $RS = mysqli_query($link,$SQL);
            if($RS && $row = mysqli_fetch_array($RS)){
                // process query result
            }
            else
            {
                $response["errorCode"]=4;    
                $response["errorDesc"]="Error descr";   
            }
            mysqli_close($link);

        }catch (Exception $e) {
            $response["errorCode"]=1;
            $response["errorDesc"]="Database Error: " . $e->getMessage();
        }
    }else{
        $response["errorCode"]=2;
        $response["errorDesc"]="Invalid Parameters";
    }

    echo json_encode($response);
?> 

I get Invalid Parameters, showing that isset($var) failed

The variable $someVar is already available to you in someScript.php. You should not use a query string to do transfer it.

If you want to avoid modifying someScript.php for some reason then you can do this:

$_GET['var'] = $someVar; 

Or just this:

$_GET['var'] = $_POST['var'];
