    Good day all, Please help.

    I try to change a list of info where it currently show all the user IDs, it should show “you” for the current logged in user in the list.
    So I’m trying to use the if else statement but it does not show the user as you.

    Please see my code before the change: <?php echo $result->id; ?> This is working correctly and shows all the users IDs.
    Here i is with my if else statement: if ($user = $result->id){
    <?php echo You ?>;}
    else {
    <?php echo $result->id; ?> }
    I have tried it with and without the {} brackets. I have even tried a JavaScript with the if else statement. And I also tried adding this $user = wp_get_current_user(); before the list, but it wont work.

    Here is the output I get: 

    if ($user = $result->id){
Notice: Use of undefined constant You - assumed 'You' in 
You} else { 39 }

if ($user = $result->id){
Notice: Use of undefined constant You - assumed 'You' in 
You} else { 38 }

    39
R5,000.00

38

  • Hi @roelfk7,

    I think you forgot to add quotes before and after ‘You’ and a semicolon ; before the closing php tag ?>.

    It should be <?php echo 'You'; ?>

    Thanks,
    M

    Also, you have if ($user = $result->id). While this may do what you want, you are also inadvertently assigning the value of $result->id to $user, which I doubt is your intent. To check equivalency without assignment, use the == operator instead of =. You could also verify type matching with ===. Usually not that important, but sometimes it’s crucial, for example
    0 == false returns true, but
    0 === false returns false. This can make a huge difference in functions like strpos()

    Thank you both. I have tried your suggestions and now it returns the following:

    if ($current_user->user_login == $result->name){ You} else { 40 }

    My code now looks like this:
    <?php
    $current_user = wp_get_current_user(); ?>
    if ($current_user->user_login == $result->name){
    <?php echo 'You' ?>}
    else {
    <?php echo $result->id; ?> }
