Everything wroks fine but is that when i try to insert null value it only uses the php validation and no alert box appear(i guess it not running the javascript validation)  .. This is the code :

 

 

<html>

<head>

<title>send New MySQL User</title>

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

<head>

<script language="JavaScript">

function checkForm()

{

var cfirstname, clastname, cage, cemail;

with(window.document.msgform)

{

cfirstname = firstname;

clastname = lastname;

cage = age;

cemail = email;

 

}

 

if(trim(cfirstname.value) == '')

{

alert('Please enter your name');

cfirstname.focus();

return false;

}

else if(trim(cemail.value) == '')

{

alert('Please enter your email');

cemail.focus();

return false;

}

else if(!isEmail(trim(cemail.value)))

{

alert('Email address is not valid');

cemail.focus();

return false;

}

else if(trim(cage.value) == '')

{

alert('Please enter your message');

cage.focus();

return false;

}

else

{

cname.value = trim(cname.value);

cemail.value = trim(cemail.value);

csubject.value = trim(csubject.value);

cmessage.value = trim(cmessage.value);

return true;

}

}

 

function trim(str)

{

return str.replace(/^\s+|\s+$/g,'');

}

function isEmail(str)

{

Change the onclick attribute to an onsubmit attribute and place it as an attribute of the form element.

 

Make sure the onsubmit function returns false if the validation of your form fails.
