Ajax Validation Engine: Pass extra parameter

Question

I am using the ajax ajaxNameCall function to check if a username exists in the database then alert the user if that username is taken or not. I have it working however I need an extra check due to updates. If admin wants to update a users record the check runs against the username sees that user already exists and produces the message. I want to pass an extra parameter of the userID so that I can avoid this situation. Is there any way to use the extraData field in ajax validator to give it the userID?

Call to Ajax from users.php

userName: {
                    title: 'User Name',
                    list: false,
                    width: '15%',
                    list: true,
                    edit: false,
                    inputClass: 'validate[required,custom[onlyLetterNumber],maxSize[20],ajax[ajaxNameCall]]'
                },

ValidationEngine:

"ajaxNameCall": {
                // remote json service location
                "url": "scripts/validationEngine/ajaxValidateFieldName.php",
                // error
                "alertText": "* This name is already taken",
                // if you provide an "alertTextOk", it will show as a green prompt when the field validates
                "alertTextOk": "* This name is available",
                // speaks by itself
                "alertTextLoad": "* Validating, please wait"
            },

Could I instead use the ajaxUserCallPhp function with the extraData field to pass in the userID from my form:

"ajaxUserCallPhp": {
                "url": "phpajax/ajaxValidateFieldUser.php",
                // you may want to pass extra data on the ajax call
                "extraData": "name=eric",
                // if you provide an "alertTextOk", it will show as a green prompt when the field validates
                "alertTextOk": "* This username is available",
                "alertText": "* This user is already taken",
                "alertTextLoad": "* Validating, please wait"
            },

If so.. How do I pass the parameter? From playing about with it all I could manange was to hardcode the userID in the extraData field (which is useless). Cant figure it out =(

Answer 1

Here is the implementation

Go to jQuery-Validation-Engine/demos/demoAjaxInlinePHP.html in above file extraction.

Run it on your local machine.

I have added the hidden input field which is getting passed with the ajax validation of text field.

Hope this will solve your problem :)

I have modified following files to get the things done :-

jquery.validationEngine-en.js

In ajaxUserCallPhp i have added "extraDataDynamic": ["#xyz"], property.

Go through the example i have attached, you will understand the implementation.
