js check if username/email is used

hi as in title, there's a method to check in ajax if username or email is already used?

Hi alfredacino,

You can do it using AJAX in the form or with Custom Serverside validation after the form is submitted.

There's an AJAX example in this paid tutorial.

thanks, and if i would just show onsubmit the various errors (server side) that the user could do?
I mean the errors the debugger print, how can i set this visible to the user?
user name already taken, wrong email form, password verify don't matched, uploaded file size exceeds the allowed limit...

Hi alfredpacino,

You can use the Custom Serverside Validation action in ChronoForms to run your own tests and show your messages.

Bob

i know🙂
but these arent'my custom validation.. i mean the default server validations already in.
i didn't set any username server validation (or email form), but i see in debugger

Validation Errors: 
Array
(
    [0] => Nome utente utilizzato
)
Debug Data
Couldn't save new user, Joomla returned this error : Nome utente utilizzato

i want to set these messages visible to the all users, without debugger.

Hi alfredacino,

Please add an Event Loop action to the pink On Fail event of the Joomla! Registration action.

Bob

i really appreciate your support, man.

some sample easy forms (joomla registration, file upload, a simple custom js validation) would help many users for these issue and save your time and forum db space🙂
all those actions are not so easy to understand: where they have to placed and what they do exactly

Hi alfredacino,

Most of those are covered in FAQs, some with videos. There's a PDF Tutorial for Joomla! Registration which includes the Event Loop step. (Though I see the link from the FAQ is broken since the site upgrade :-(

Hi I just purchased your paid tutor, but it is not working, maybe because I'm doing something bad, sorry I'm mew here.

I'm using the advanced wizard and I put the "Load JS" with the code of your tutor in the event "ON LOAD" and I created the event "ajax"with the PHP database query on that event.

Now I double checked the variables, the database connection, etc etc but the sample is not working😟, nd nothing happen, please maybe yu can clarify the thing

Tank you

Hi vivora66,

Please post a link to the form so I can take a quick look.

Bob

Something is wrong with the returning function

           onComplete: function(r) {
               // check the result and set the background color
               if ( r == 'ok' ) {
                  pepinous.setStyle('background-color', 'green');
               } else {
                  pepinous.setStyle('background-color', 'red');
               }
            }

Allways, scritp after the AJAX PHO functions goes to r<>'ok' displaying my from in red

hi this is the link
http://www.boliviabox.com/index.php?option=com_chronoforms&tmpl=component&chronoform=suscripcion_usuario

In checking the "Nombre de Usuario" field to chek in my DB id the user is "IN USE", just works checking the length of characters, puting yellow when it is lower than 6 chars, whein it is over 6 goes to the AJAX function but always it is returning "IN USE" because the color of the form is in RED ALWAYS, is like the function always check the DB returns a "IN USE" value
Please letme know how I can show the return value to be sure maybe in the upper part of field

your tutor work well, changing the colors of field, but how i can also display a message like "email in use" and how i could nos process the form when pressing submit, i mean do not process anything until the r = 'ok'
please helpme
