Hey ninobysa,
I am still working on my multistep form, i realized that i would need to create my own validation.
$(".nextone").click(function(e){
e.preventDefault();
$.ajax({
dataType: 'json',
type: 'POST',
url: ajaxurl,
data: {
action: 'epm_registration_process',
epformdata: $('#field-group-1 input, #field-group-1 select').serialize()
},
success: function(resp) {
if (resp === true) {
//successful validation
if(animating) return false;
animating = true;
current_fs = $(this).parent();
next_fs = $(this).parent().next();
//activate next step on progressbar using the index of next_fs
$("#progressbar li").eq($("fieldset").index(next_fs)).addClass("active");
//show the next fieldset
next_fs.show();
//hide the current fieldset with style
current_fs.animate({opacity: 0}, {
step: function(now, mx) {
//as the opacity of current_fs reduces to 0 - stored in "now"
//1. scale current_fs down to 80%
scale = 0.8 + (1 - now) * 0.2;
//2. bring next_fs from the right(50%)
left = (now * 50)+"%";
//3. increase opacity of next_fs to 1 as it moves in
opacity = 1 - now;
/*current_fs.css({
'transform': 'scale('+scale+')',
'position': 'absolute'
});*/
next_fs.css({'opacity': opacity});
},
duration: 0,
complete: function(){
current_fs.hide();
animating = false;
},
//this comes from the custom easing plugin
easing: 'easeInOutBack'
});
return false;
} else {
$.each(resp, function(i, v) {
console.log(i + " => " + v); // view in console for error messages
if( $('input[name="' + i + '"], select[name="' + i + '"]').hasClass('inputTxtError') ){}else{
var msg = '<div class="acf-notice -error acf-error-message"><p>'+v+'</p></div>'
$('input[name="' + i + '"], select[name="' + i + '"]').addClass('inputTxtError').before(msg);
}
});
var keys = Object.keys(resp);
$('input[name="'+keys[0]+'"]').focus();
}
return false;
},
error: function(errorThrown) {
console.log(errorThrown);
}
});
return false;
});
PHP CODE:
function epm_registration_process($post_id){
//Prepare basic user info
$username = strtolower($_POST['acf']['field_5b4be98fd288c']);
$firstname = $_POST['acf']['field_5b4be9d8d288d'];
$lastname = $_POST['acf']['field_5b4be9e8d288e'];
$email = $_POST['acf']['field_5b4be9f7d288f'];
$password = $_POST['acf']['field_5b4bea0bd2890'];
$cpassword = $_POST['acf']['field_5b4bea8bd2891'];
$error = array();
//IMPORTANT: You should make server side validation here!
if( empty($username) ){
$_SESSION['errors']['acf[field_5b4be98fd288c]'] = "Please enter a username";
}elseif(username_exists( $username )){
$_SESSION['errors']['acf[field_5b4be98fd288c]'] = "Username already exist";
}
if( empty($firstname) ){
$_SESSION['errors']['acf[field_5b4be9d8d288d]'] = "Please enter your firstname";
}
if(count($_SESSION['errors']) > 0){
//This is for ajax requests:
if(!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
echo json_encode($_SESSION['errors']);
exit();
}
//This is when Javascript is turned off:
echo '<ul>';
foreach($_SESSION['errors'] as $key => $value){
echo '<li>' . $value . '</li>';
}
echo '</ul>';
exit();
}else{
//form validation successful - process data here!!!!
}
}
add_action('wp_ajax_epm_registration_process', 'epm_registration_process');
add_action('wp_ajax_nopriv_epm_registration_process', 'epm_registration_process');
add_filter('acf/pre_save_post' , 'epm_registration_process', 10, 1 );
I am stuck at how can i get $_POST data if form does not submit the normal way hence i cannot validate against a user already existing in the database etc… i am only able to check if the field is empty
