Question

I have a PHP variable thats value is set at the start of my document but when I use my WHILE LOOP it get UNDEFINED and stops working.

Can anyone help how to keep this value assigned?

The variable I’m trying to keep defined is $lang

$lang = "en";// base url


function getAccountDeliveryDetails($id){
    $query  = "SELECT * FROM tbl_user_delivery WHERE user_id = '$id'";
    $result = mysql_query($query);

    while($row = mysql_fetch_array($result)){
    $phrase =   array(  
                            'de'    =>  'Bearbeiten',
                            'en'    =>  'Edit',
                            'es'    =>  'Editar',
                            'fr'    =>  'Éditer',
                            'it'    =>  'Modifica');
                        echo $phrase[$lang];
    }   
}

Answer 1

inside a function you need to use global. first line in function

function getAccountDeliveryDetails($id){
    global $lang;

    $query  = "SELECT * FROM tbl_user_delivery WHERE user_id = '$id'";
    $result = mysql_query($query);

    while($row = mysql_fetch_array($result)){
    $phrase =   array(  
                            'de'    =>  'Bearbeiten',
                            'en'    =>  'Edit',
                            'es'    =>  'Editar',
                            'fr'    =>  'Éditer',
                            'it'    =>  'Modifica');
                        echo $phrase[$lang];
    }   
}
