How to extend with own rules

[Stanislaw Nalepa]

Hello Dinesh.

I have tested an extension to jQuery Validation, in JSFiddler it works as expected. So now I wonder how I could integrate this function in your plugin “jquery validation for contact form 7”. the code below begins with two fields which were in the example already, it is the third field that runs the validation I need in my form.

/*
$(document).ready(function () {

$(‘#myform’).validate({
rules: {
field1: {
required: true,
integer: true
},
field2: {
required: true,
integer: true
},
field3: {
required: true,
myPersonnummerkoll: true
}
},
submitHandler: function (form) { // for demo
alert(‘valid form’);
return false;
}
});

jQuery.validator.addMethod(‘integer’, function (value, element, param) {
return (value != 0) && (value == parseInt(value, 10));
}, ‘Please enter a non zero integer value!’);
$.validator.addMethod(“myPersonnummerkoll”, function(value, element) {
var pnr = value;
// Do formatting and sanity control
pnr = pnr.replace(/[^0-9]/g, ”); // only keep digits
if (12 == pnr.length) // year format 1985 → 85
pnr = pnr.substr(2);
if (10 != pnr.length) // check length
return false;
if (pnr.substr(2,2) > 12) // check month
return false;
if (pnr.substr(4,2) > 31 || pnr.substr(4,2) == 0) // check date
return false;
var parts = pnr.split(”).map(function(i){
return Number(i);
});
// Then run the mod 10 algorithm to produce check digit
var control = parts.pop();
var inc = 0, multiplicator = 2, product;
for (var i in parts) {
product = parts[i] * multiplicator;
if (product > 9)
inc += product – 9;
else
inc += product;
multiplicator = multiplicator == 1 ? 2 : 1;
}
var control_ = 10 – (inc – Math.floor(inc/10)*10);
if (10 == control_)
control_ = 0;
if (control == control_)
return true;
}, “Personnumret är ofullständigt eller i fel form!”);
});*/
