Why does this not work??

[homchz]

[code]
class navigation
{
    var $u_links = array(
                    'Home'    => 'http://www.domain.com',
                    'Profile' => '?page=profile&uid=$u_id',
                    'Search'  => '?page=search');

    function navigation()
    {
         
    }
    
    function get_nav($u_id)
    {        
        foreach($this->u_links as $title => $url)
        {
            print "<a href=\"$url\">$title</a><br/>";
        }
    }
}

[/code]

The profile links does not recognize $u_id it only prints the literal $u_id.

Is this not possible??

'Profile' => '?page=profile&uid=$u_id',


is there a ? missing only guessing.

[homchz]

nope the format is correct. I just thought it would pick up the variable.

Change [code]<?php 'Profile' => '?page=profile&uid=$u_id' ?>[/code] to [code]<?php 'Profile' => "?page=profile&uid=$u_id" ?>[/code]
Variables inside single quotes are not evaluated, those contained within double quotes are expanded.

Tried that too but if I use double quotes in the array I get an"

Unexpected '"' error on that line.

This should work:
[code]<?php
    var $u_links = array(
                    'Home'    => 'http://www.domain.com',
                    'Profile' => "?page=profile&uid=$u_id",
                    'Search'  => '?page=search');
?>[/code]
or
[code]<?php
    var $u_links = array(
                    'Home'    => 'http://www.domain.com',
                    'Profile' => '?page=profile&uid=' . $u_id,
                    'Search'  => '?page=search');
?>[/code]

I'll advise you that it's probably not going to work as expected.

The variable in the array will be extended but it will have an empty value.

Yes I tried both methods before posting here and actually recieved errors. I got around this by passing a session variable and not URL variable.

Thanks for the advice though,
