<input type="checkbox">

[watagal]

Greetings--I'm not sure if anything is wrong or this is normal behavior? But when a checkbox is unchecked, it returns a null value (generating the notices in the output window)My HTML:

<input class="checkbox" type="checkbox" name="chkRememberUserName" tabindex="3" value="OFF">

My PHP code which is called on form's submittal:

echo 'chkRememberUserName  = '.$_POST['chkRememberUserName'].'<br />';echo 'chkRememberPassword  = '.$_POST['chkRememberPassword'];$postRememberUserName = $_POST['chkRememberUserName'];$postRememberPassword = $_POST['chkRememberPassword'];

Output:

chkRememberUserName  = chkRememberPassword  = onNotice: Undefined index: chkRememberUserName in D:\xampp\htdocs\_mysites\ck.com\Html_php_code\processSignIn.php on line 13Notice: Undefined index: chkRememberUserName in D:\xampp\htdocs\_mysites\ck.com\Html_php_code\processSignIn.php on line 15

Can someone confirm this or let me in on the fix?TiA, Gal

Yup. This is where we use those wonderfully special php routines isset() and empty(), thus:if (isset ($_POST['galsval']) && !empty($_POST['galsval']) ) {// do something swell}And yes, you'll want to do this for every post and get variable, but after a while, it's just cut and paste.

or better yet write a function to do it

function postEmptyOrNull($var) {   if (!isset ($_POST[$var]) || empty($_POST[$var]) ) {	 return TRUE;   }   return FALSE;}  //use like this if(!postEmptyOrNull('galsval')) {   //do something }
