Global_variable off?

eddyvlad · #1 (**permalink**) 10-03-03, 02:33 PM

I just upgraded my PHP and ohh boy.. They turned off the global variable and now I get lots and lots of Undefined Variable. I don't want to turn it back on coz I'm aware of the security issue. So... Umm. How do I make my code compatible with the global variable turned off?

My code is messy isn't it?

I only had 1months experience in PHP and i'm still learning.. So pls bear with me.

PHP Code:


			
$username="default";

$password="shibby";

$database="dude";



###############################################

mysql_connect('localhost',$username,$password);

@mysql_select_db($database) or die( "Unable to select database");



if($_POST['submit']){ 

    $insert = "INSERT INTO journal (date,time,content) VALUES ('$date','$time','$content')";

    mysql_query($insert);

}

elseif($update){

    $update = "UPDATE journal SET date='$date', time='$time', content='$content' WHERE id='$id'";

    mysql_query($update);

}

elseif($action == "del"){

    $delete = "DELETE FROM journal WHERE id='$id'";

    mysql_query($delete);

}



#####################################################

if($action == "edit"){



    $edit = "SELECT * FROM journal WHERE id='$id'";

    $edit_result = mysql_query($edit);

    $edit_rows = MySQL_fetch_array($edit_result);



    $the_id = $edit_rows['id'];

    $the_date = $edit_rows['date'];

    $the_time = $edit_rows ['time'];

    $the_content = $edit_rows ['content'];

}

else{

    $the_time = date("g.i:s a", time());

    $the_date = date("l, d F Y");

}

Feel free to list the errors that you are getting...

Turn all the values you got from post forms into $_POST['fieldname'], all values from a query string into $_GET['somename'], session vars come from $_SESSION, cookies form $_COOKIE...
