in this code the php is not making the cookie can any one tell me why

 

 

 

<?php
function getRandomString($length = 5) {
    $validCharacters = "abcdefghijklmnopqrstuxyvwzABCDEFGHIJKLMNOPQRSTUXYVWZ+-*#&@!?1234567890";
    $validCharNumber = strlen($validCharacters);

    $result = "";

    for ($i = 0; $i < $length; $i++) {
        $index = mt_rand(0, $validCharNumber - 1);
        $result .= $validCharacters[$index];
    }

    return $result;
}
setcookie("code", "getRandomString()", 3600000);
echo getRandomString();
?>

Unquote the function call in setcookie().

That was not the only problem i was missing the time() in my expire lol all fix thanks for your help

[bob2006]

i know this has no relation to this post but how can i do this

function getRandomString($length = 75) {
    $validCharacters = "abcdefghijklmnopqrstuxyvwzABCDEFGHIJKLMNOPQRSTUXYVWZ+-*#&@!?1234567890";
    $validCharNumber = strlen($validCharacters);

    $result = "";

    for ($i = 0; $i < $length; $i++) {
        $index = mt_rand(0, $validCharNumber - 1);
        $result .= $validCharacters[$index];
    }

    return $result;
}
$string= 'getRandomString';
$expire=time()+60*60*24;
setcookie("code", getRandomString(), $expire);
mysql_query("UPDATE admin SET cookie_code='$string' WHERE login='$username'")or die(mysql_error());

how can you do what?

[bob2006]

I am trying to update a variable in the databases called cookie_code with the function getRandomString

 

mysql_query("UPDATE admin SET cookie_code='21121' WHERE login='$username'")or die(mysql_error());

but all it is putting in the databases is getRandomString() And not the string i know it is doing this because the Function is not a virable so i try make it a Variable

$string= 'getRandomString';

and that did not help at all

When you enclose it in quotes, it becomes a literal string.

 

$string = getRandomString();

[bob2006]

it really that easy grr i did that because of the example here:http://php.net/manual/en/functions.variable-functions.php

 

Thank you

    $result = "";
