无法弄清楚为什么这不起作用（PHP）

So I am working on an admin panel feature in PHP 5.6 and whenever I try to switch a user to Admin it will set them to Builder I have no idea where or what I am doing wrong Here is the code

this is updateusera.php

     <?php include 'core/init.php';


$id   = $_GET['id'];
$type   = $_GET['type'];

if($type == 'admin'){
    mysql_query("UPDATE `users` SET `type` = 'user' WHERE `user_id` = '$id'");
     header('location: changeusers.php');

} else if($type =='user'){
    mysql_query("UPDATE `users` SET `type` = 'admin' WHERE `user_id` = '$id'");
    header('location: changeusers.php');

}

//=========================================================================

if($type == 'moderator'){
    mysql_query("UPDATE `users` SET `type` = 'user' WHERE `user_id` = '$id'");
     header('location: changeusers.php');

} else if($type =='user'){
    mysql_query("UPDATE `users` SET `type` = 'moderator' WHERE `user_id` = '$id'");
    header('location: changeusers.php');

}

//=========================================================================

if($type == 'builder'){
    mysql_query("UPDATE `users` SET `type` = 'user' WHERE `user_id` = '$id'");
     header('location: changeusers.php');

} else if($type =='user'){
    mysql_query("UPDATE `users` SET `type` = 'builder' WHERE `user_id` = '$id'");
    header('location: changeusers.php');

}
?>

this is the changeusers.php file

for some reason it would not let me put both of my codes in here P.S I am new to Stackoverflow so i'm still getting use to all this

if anyone has an idea I would love to hear it

Thanks!

You have three else if statements which is true when $type =='user'. Everything in these else if executing and three queries send, last of them set type builder.

You need to pass in parameters type which you need to set. That way:

if($type == 'admin') {
    echo "<a href='updateusera.php?id=&type=user'>Revoke Admin </a>";
} else {
    echo "<a href='updateusera.php?id=$id&type=admin'>Grant Admin </a>";
}
if($type == 'moderator') {
    echo "<a href='updateusera.php?id=$id&type=user'>Revoke Moderator </a>";
} else {
    echo "<a href='updateusera.php?id=$id&type=moderator'>Grant Moderator </a>";
}
if($type == 'builder') {
    echo "<a href='updateusera.php?id=$id&type=user'>Revoke Builder</a>";
} else {
    echo "<a href='updateusera.php?id=$id&type=builder'>Grant Builder</a>";
}

Then you code need to be like that:

if($type == 'user') {
    mysql_query("UPDATE `users` SET `type` = 'user' WHERE `user_id` = '$id'");
    header('location: changeusers.php');
    exit;
}
if($type == 'admin') {
    mysql_query("UPDATE `users` SET `type` = 'admin' WHERE `user_id` = '$id'");
    header('location: changeusers.php');
    exit;
}
if($type == 'builder') {
    mysql_query("UPDATE `users` SET `type` = 'builder' WHERE `user_id` = '$id'");
    header('location: changeusers.php');
    exit;
}

You want to change your else if statements to if statements; Basically all the else if statements are being executed and the last else if statement is set to builder.
