Jquery/Ajax form Post data is not working

I'm not expert with Jquery. I've built a 4 steps html form like

<form id="msform" enctype="multipart/form-data">
    <fieldset id="publish1" data-check-id="1">
        //some inputs
    </fieldset>
    <fieldset id="publish2" data-check-id="2">
        //some inputs
    </fieldset>
    <fieldset id="publish3" data-check-id="3">
        //some inputs
    </fieldset>
    <fieldset id="publish4" data-check-id="4">
        <input type="submit" class="submit action-button pull-right top-35" value="Publish"/>
    </fieldset>
</form>

and after writing some Jquery validation in my .js file, I've tried to pass my data to a php file through ajax. My formData function looks like this:

<script>
    function formData() {
        var serializedValues = jQuery("#msform").serialize();
        var form_data = {
            action: 'ajax_data',
            type: 'post',
            data: serializedValues,
        };
        jQuery.post('mypath/insert.php', form_data); //where data should be sent
        return true;
    }
</script>

Searching around I've tried to build the php file receiving data with this structure:

<?php
if (isset($_POST['data'])) {
    post_things();
    return true;
}

function post_things() {
    $title = trim($_POST['form_title']);
    // where form_title is the input[name] of what I want get, serialised into jquery serializedValues variable
    //other similar inputs
    //do something with $title and other $variables
}
?>

I've initialized validation and ajax functions doing something as following:

<script>
    $(document).ready(function () {
        msform_init(); //this validate form step by step (it's working!)
        $('#msform').submit(function (event) {
            if (form_completeCheck() && true) { //This check if something empty
                formData();
                if (formData() && true) {
                    window.location.replace("//some redirection to success");
                } else {
                    window.location.replace("//some redirection to failure");
                }
            } else {
                event.preventDefault();
            }
        })
    })
</script>

The problem is that when I click on submit I got redirected to a page where the url is mypath? ALL_MY_DATA_SERIALISED. Where is my error? I can't see it due to my ignorance. Is in the jquery/ajax functions, in the php file or in my html? Thank you in advance for your help.

The reason you get redirected is because you are submitting the form.

Since in your <form id="msform" enctype="multipart/form-data"> you define no action it is submitted to itself.

You must prevent form from submitting using preventDefault().

 $('#msform').submit(function(event){
   event.preventDefault(); //Add this line

You just need to do event.preventDefault() in the top of your event listener:

$('#msform').submit(function(event){
  event.preventDefault();        
  if(form_completeCheck() && true){ //This check if something empty
    formData();
    if(formData() && true){
        window.location.replace("//some redirection to success");
    } else {
        window.location.replace("//some redirection to failure");
    }
  }

})

HTML Script

<form id="msform" enctype="multipart/form-data">
    <input type="hidden" name="action" value="do_action"/>
    <fieldset id="publish1" data-check-id="1">
    //some inputs
    </fieldset>
    <fieldset id="publish2" data-check-id="2">
    //some inputs
    </fieldset>
    <fieldset id="publish3" data-check-id="3">
    //some inputs
    </fieldset>
    <fieldset id="publish4" data-check-id="4">
    <input type="button" id="do_action" class="submit action-button pull-right top-35" value="Publish"/>
    </fieldset>
</form>

JavaScript

$("#do_action").click(function(){
    $.ajax({
        type:'POST',
        data:$("#msform").serialize();
        url:'<<php script url>>',
        success:function(data){
            alert(data);
        }
    });
});

php script

<?php
    if(isset($_POST['action'])){
        post_things($_POST);
        return true;
    }
    function post_things($request){
        echo "<pre>";
        print_r($request);
        echo "</pre>";
    } 
?>
