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

--------------------------------------...

<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>";

}
?>
