<body> not loading when there's if statement

gilgalbiblewhee · 01-14-2010, 10:52 AM

Is there any way to make this work?

PHP Code:


			
function theOnload(){

    echo "<body style=\"background-color: #515151;\"";

    if($_GET["works"] == "home" or $_GET["works"] == ""){

        echo " onLoad=\"myLatestWorks();\"";

    )

    echo " >\n";

}

The onLoad shouLd load a popup div tag on the home page. If I block:

PHP Code:


			
function theOnload(){

    echo "<body style=\"background-color: #515151;\"";

    /*if($_GET["works"] == "home" or $_GET["works"] == ""){

        echo " onLoad=\"myLatestWorks();\"";

    )*/

    echo " >\n";

}

The page loads if not it shows blank.

PHP Code:


			
function theOnLoad() {
    echo '<body style="background-color: #515151"'.
        ((!isset($_GET['works']) || $_GET['works'] == 'home' || $_GET['works'] == '') ? ' onload="myLatestWorks();">' : '>');
}

Try that

With PHP, "or" is ||

if($_GET["works"] == "home" || $_GET["works"] == ""){

You're getting a blank screen because PHP failed and you don't have
error reporting turned-on. Turn on PHP error reporting via your PHP config
with your webhost control panel or using .htaccess

That wouldn't throw an error. It's perfectly logical to have OR written there. They both work

PHP Code:


			
global $_GET;

Is required within the function I'm pretty sure.

$_GET is a global, so it's not needed. Same as $_POST, $REQUEST, $_SESSION and $_COOKIE

Uh indeed.

Could you post a link to your page?

I wonder if maybe the variable "works" does not exist with the $_GET.
Would that cause a PHP "warning" ... and because the error reporting is
not enabled, it is throwing a blank screen? So, he needs to suppress warnings,
and turn-on error message to see what's happening?

At best it would cause an undefined index NOTICE, but yeah that might be enough to throw it
