using jquery to return multiple values for my registration form validation

Question

hi i am trying to carry out dynamic checks on my registration form, so when the user enters information, the php code is checking it for errors.currently, i am only trying to pass the values back to jquery to be displayed on the form, i have not yet carried out any validation on the input boxes. i can only seem to pass one value back, as soon as i try and pass multiple values, nothing gets returned, any help would be mostly appreciated.

Answer 1

You should send the whole form if you want to validate multiple inputs at once to your php.

Your validate function should look something like

function validate(fname, lname){
$.post('php/registration.php', $("form").serialize(), function(data){
        $('#fname_feedback').text(data.fname);
        $('#lname_feedback').text(data.lname);
    },'json');
}}

And your php function could be something like (until you do the validation)

$return_data=$_POST;

header('Content-Type: application/json');
echo json_encode($return_data);
exit();

}
