Re-assigning variable with if else

[perficut]

First let me apologise for such a basic command, but I need a little help with the syntax.

I have a number of variables passed into the php file from a form. I want to check and see if var#1 is left blank, if so leave var#2 alone. If  not then var#2 has the same data as var#1

Ex:
if Var#1 = " " then nothing happens
else if Var#1 has data, then Var#2 is now = Var#1


Var#2 is a persons home address
Var#1 is a persons billing address

There is always data in Var#2, thier home address, but if the billing address has filled out, then I want the Var containing their home address to now be their billing address.

If any of this makes sense. - Heck, I'm confused if I dont think slow about it. But this is probably an easy remedy.

THANKS

You might find this syntax useful

[code]
$foo = (isset($_REQUEST['new_foo']) ? $_REQUEST['new_foo'] : $foo);
[/code]

[code]
<?php
if ($data == ""){echo "";}
if ($data != ""){$data2 = $data;}
?>[/code]
Ted.
Is this what you are looking for? or its somthing else?

[code]<?php

// the action='' value in your html form leads to here
// assuming the name of the input where your home address goes is called home_address
$home_address = $_POST['home_address'];

// assuming same as above but billing address is called billing_address
$billing_address = $_POST['billing_address'];

// now let's check
if(strlen($billing_address))
{
$home_address = $billing_address;
} else {
// don't do anything, thanks
}

// continue our processing
// let me make this clear, if someone enters a blank space in the billing address, you'll have virtually a string in both variables
// but literally, nothing in both

?>[/code]

thanks guys thats what I needed. Works great now.

One final thing, when echoing data, how can do set the font/color of the echoed information.

<?php echo $BusinessName; ?>

[kamasheto]

[code]<?php echo "<font style='color:red'>" . $BusinessName . "</font>"; ?>[/code]

This is a CSS question,

[code]<?php
echo "<span style='color:red'>" . $BusinessName . "</span>";
?>[/code]
