Problem working with Windows7 OS

Posted: 17 Jan 2011 11:10 PM PST

Hi friends,
I would like to buy a laptop with core i3 processor but the dealer is suggesting me to buy core 2 duo because he is telling me that core i3 processor will support only Windows7 OS but no other OS and it will not allow to work with 'C' or 'C++' programming languages :(.
But I tried to run 'C' programs at my college under Windows7 with Pentium processor and it works fine:p. I wasn't quite sure whether I can work under core i3 processor with Windows7 or not.
I would like to know from you whether the dealer is right or wrong and which configuration would better suit for my requirements

PHP form validation problem?

Posted: 17 Jan 2011 07:02 PM PST

I'm making one form using php, so validation is using PHP too,
I m posting the value in the same form and then trying to insert into mysql..look below.. I encountered the problem
--------------------------------------…
Code:
<form method="post" enctype="multipart/form-data" name="form1" id="form1">

Name : <input type="text" name="t1" id="t1" />
Contact : <input type="text" name="t2" id="t2" />

<span class="err" ></span>

<input type="submit" name="s1" id="s1" /> 
</form>

<?php
if(isset($_POST["s1"]))
{
if($_POST["t1"] == "")
{
$err = "Enter Your name";

echo "<script language=javascript>" . "alert('Enter your name')" . "</script>";
echo "<script language=javascript>" . "document.getElementById('t1').focus();" . "</script>";
}
else if($_POST["t2"] == "")
{
$err = "Enter Your Contact Number";
echo "<script language=javascript>" . "alert('Enter your contact number')" . "</script>";
}

echo "<span style=color:red> $err</span>";
}

?>
--------------------------------------…
