1. Check if $_POST['action'] is set before using it. For example:
if (!isset($_POST['action']))
{
//If not isset -> set with dumy value
$_POST['action'] = "undefine";
}
2. Suppress Notice warnings
Notice warnings could be suppressed by changing the error_reporting variable in your PHP.ini. error_reporting could be set to show all errors except those for notices and coding standards warnings: error_reporting = E_ALL & ~E_NOTICE
The same is accomplished by adding the following line in your php page:
<?php error_reporting(E_ALL ^ E_NOTICE); ?>

For example if you want to load a specifis style sheet for IE, just write :
<!--[if IE]>
<link rel="stylesheet" type="text/css" href="{vb:raw vbcsspath}vbulletin-ie.css" />
<![endif]-->
This will allow the link to the style sheet only if the browser is IE not for others
You can also link style sheets according to various versions of IE , like this :
<!--[if IE6]>
<code>
<![endif]-->
And if you want to apply style sheet for all except IE , then write :
<!--[if !IE]><!-->
<link rel="stylesheet" type="text/css" href="not-ie.css" />
<!--<![endif]-->
This could easily be done with javascript : For example : If your html file is like this: <html><head>....</head><body> <div id="testdiv" style="display:block;"> .......... <input type="button" id="sub" onClick="displayBlock()"> </body></html> And you want to hide the div ‘testdiv’ on the click event of button ‘sub’ , just write the following javascript code in the head tag of the same file : <script type="text/javascript"> function displayBlock() { document.getElementById('testdiv').style.display='none'; } </script> This code will call the displayBlock function on the button click and hide the div whose id will be ‘testdiv’.
