Question

I have the following code that sets a background if user has uploaded to database. If user has NOT uploaded an image then the result is a blank img src=”

I need to set this as an if isset function so I can plug in an alternate image if user has not uploaded anything.

Here is the current code:

<div id="background"><?php echo isset($background_image) && file_exists(ROOT.$background_image)?"<img src='$background_image' alt='' />":'';?></div>

Your code’s a little dirty, opening php and closing it mid-html tag is only going to make it confusing for you in the future.

You’re echoing back an isset which is just echo’ing back a boolean.

Try this;

$background_image = ""; // Not sure what you're using here - their username? Dump it in here anyway.
if (file_exists($background_image))
{
    echo "  <div id=\"background\">
            <img src=\"{$background_image}\" alt=\"\" title=\"\" />
        </div>";
}

Hope this helps.
