[SOLVED] Variables and functions in different files

[envexlabs]

Hey,

 

I have 2 files, index.php and functions.php

 

in index.php

<?php if ($au=$_SESSION['_amember_user']){ // user is logged-in
print "<p>Hello $au[name_f] $au[name_l]!</p><br>";
print "<a href='/amember/logout.php'>Logout</a>";
} 
else { // user is not logged-in
                    
print '<p>Hello!</p>
<a href="javascript:login_fade();">Login</a>';

}?>

display_nav();

 

in functions.php

 

function display_nav(){
    $nav_display = mysql_query('SELECT * FROM `amember_payments` WHERE `member_id` = "' . $au[member_id] . '"');
    $nav = mysql_fetch_row($nav_display);
    
    //renders out the navigation depending on the user
    if($nav[2] == 1)
    {
        //user
        user_nav();
    }
    elseif($nav[2] == 2 || $nav[2] == 3)
    {
        //store
        store_nav();
    }
    else{
        //guest
    }
}

 

I have included the functions.php in index.php, but for some reason display_nav(); doesn't work. If i copy the function into index.php it works.

 

Why are my variables from index.php not working in function.php even though function.php is included in index.php

 

Any help is appreciated!

 

Thanks.

Put the call to the function between <?php and ?>...

hey,

 

i tried that.

 

the problem is $au[member_id] isn't being recognized in functions.php

[Orio]

if ($au=$_SESSION['_amember_user'])

Should be

if ($au==$_SESSION['_amember_user'])

 

Maybe that'll fix the problem.

hey,

 

the variable has been set and is recognized in index.php

 

it is not recognized in functions.php, which is the problem i am trying to fix.

Oh of course lol

It's a scope issue- $au is in the global scope...

To solve this, add in the first line of the function: global $au;
