I'd like to learn how data is passed form one file to another and then
displaying at when an error occurs.
I have this php script that checks if an domain really exist
phpfile: check_domain.php
list($userName, $hostName) = split("@", $request);
// Function to check whether a given hostName is a valid email
// domain address.
function myCheckDNSRR($hostName, $recType = '')
{
if(!empty($hostName)) {
if( $recType == '' ) $recType = "MX";
exec("nslookup -type=$recType $hostName", $result);
// check each line to find the one that starts with the host
// name. If it exists then the function succeeded.
foreach ($result as $line) {
if(eregi("^$hostName",$line)) {
return true;
}
}
// otherwise there was no mail handler for the domain
return false;
}
return false;
}
$valid = 'false';
// If you are running this test on a Windows machine, you'll need to
// uncomment the next line and comment out the checkdnsrr call:
if (myCheckDNSRR($hostName,"MX"))
//if (checkdnsrr($hostName,"MX"))
$valid = 'true';
else
$valid = 'false';
echo $valid;
?>
It splits an email address into two parts, $userName and $hostName.
But only $hostName is used for the domain check.
javascript:
<script type="text/JavaScript">
$(document).ready(function () {
$("#test").validate({
rules: {
email: {
required: true,
email: true,
remote: "domain_check.php" // checks to see if
the given domain
name is valid
},
},
messages: {
email: {
email: "email address is invalid",
required: "your email address.",
remote: jQuery.format("the domain does not
exist or is
misspelled.")
}
}
});
});
</script>
html form
<form name="check" action="#" method="post" id="test" style="margin-
top:100px; margin-left:300px;">
<label for="email" id="test">uw e-mailadres</label>
<input type="text" id="email" name="email"
style="border:dotted 1px #000;" class="man" />
<input type="submit" name="send" value="send"
style="width:auto;" />
<input type="reset" value="cancel" style="width:auto;" />
</form>
Now i like to see that the php variable $hostName is passed to
remote:jQuery.format().
I believe that ajax is needed or validator.addMethod or both, but I
have no idea how that is done.
Any help is welcome and appreciated.
