[SOLVED] Variable is blank, how to substitute?

[PHP Nubsauce]

Hi,

 

I have

 

$username = user_name

$firstname = first_name

$lastname = last_name

addedby = $firstname' . '$lastname

 

How can I make it so if firstname and lastname are blank, it uses username instead?

 

Any help would be appriciated!

 

Thanks,

 

Nubsauce.

<?php

$username  = $_POST["user_name"];
$firstname   = $_POST["first_name"];
$lastname   = $_POST["last_name"];
$addedby   = "$firstname $lastname";

if($firstname == "" && $lastname == ""){
$username = "$firstname $lastname";
}

// other codez

?>

 

Im not even good in php, but this is just a guess

You should use the empty() function or !isset(). Double quotes sometimes are read as a single space, don't know why, but it has happened to me.

 

<?php

$username  = $_POST['user_name'];
$firstname   = $_POST['first_name'];
$lastname   = $_POST['last_name'];
$addedby   = $firstname . $lastname;

if(empty($firstname)) {
$username = "Username"; //You can change this to whatever you want username to be if it's blank
}
else if(empty($lastname)) {
$username = "Username"; //You can change this to whatever you want username to be if it's blank
}

// other codez

?>

 

You didn't give enough information in your post PHP Nubsauce, so no idea how you want it to be coded.

i have

 

$username = user_name

$firstname = first_name

$lastname = last_name

addedby = $firstname' . '$lastname

 

Yeah,

 

sorry i was unclear,

 

If firstname and lastname are both blank, I'd like addedby to be username.

 

Thanks.

 

 

[Nexy]

addedby = $firstname' . '$lastname

 

The values of your variables, should be in quotes, if they are strings.

 

Also, is addedby a variable? You don't have "$" in front of it.

Ok, I was at work, forgive me, I could not copy and paste my code.

 

$username = $_SESSION['loggedin'];

$firstname = $t['first_name'];

$lastname = $t['last_name'];

$addedby = $firstname. " " .$lastname;

 

This all works fine.

 

All I'd like to do is replace "addedby" with "username" if both firstname and lastname are blank.

 

Thanks for your patience.

$username = $_SESSION['loggedin'];
$firstname = $t['first_name'];
$lastname = $t['last_name'];
$addedby = $firstname. " " .$lastname;

if(empty($firstname) && empty($lastname)) {
        $addedby = $_SESSION['loggedin'];
}
?>
