[jQuery] [validate] Beginners question. How to pass data from remote file to jQuery.format
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.
