Hi anuka,

<?php
//Check whether the submission is made
if(!isset($_POST["hidSubmit"])){ $stremail="";
DisplayForm();
}
else{

//Validate the Email Address
$stremail=$_POST["txtemail"];
$result=ereg("^[^@ ]+@[^@ ]+\.[^@ ]+$",$stremail,$trashed);
if(!$result){
echo "Enter a valid E-mail Address";
DisplayForm();
}
else{
echo "E-mail Address is Ok";
$stremail="";
DisplayForm();
}
}

//User-defined Function to display the form in case of Error
function DisplayForm(){
global $stremail;
?>


<form name="form1" method="post" action="">
<table width="100%" border="1" align="center" cellpadding="0" cellspacing="0" bordercolor="#0033FF" bgcolor="#DEE3EF" >
<tr><td width="100%"><table width="60%" border="0" align="center" cellpadding="0" cellspacing="0" bgcolor="#DEE3EF">
<caption align="top" class="heading">
E-Mail Validation
<br>
<tr>
<td width="46%"><br>
<div align="right">Enter An Email Address </td><td width="54%"><br>
<input name="txtemail" type="text" class="textbox" id="txtemail" value="<?php echo $stremail; ?>">
</tr>
<tr>
<td colspan="2"> <div align="center"><br>
<input name="Submit" type="submit" class="button" value="Submit">
<input name="hidSubmit" type="hidden" value="true">

Ok. anuka,

But, if u want to do this u have to work with the database isn't it..

what i am trying to say is if we want to do comparison then we must require two fields...

so first u store that [email protected] in to the databaseb table..then compare this with the user input(using database connections)... ok ya?
