jQuery Multiple Forms Submit

I have 4 forms on a page. I know that forms cannot be nested.

<form id="form1"></form>

<form id="form2"></form>

<form id="form3"></form>

<form id="form4"></form>

presented in that order.

Form 1 and Form 4 post to same php page for processing. Form 1 have 1 input field Form 4 have multiple fields, checkboxes and selects.

What is the best approach for both form 1 or form 4 sending the combined fields of both forms?

I've tried jQuery, works great for text input and checkbox, but can't get it to work with Select. Tried combining form 1 and form 4 and using css to repositioning form 1, but can't get the layout right.

Is there something simpler to do this?

It's not possible. You can either use serialize() or serializeArray() method for getting forms' data and post them to the server using Ajax:

Encode a set of form elements as a string for submission.

$('#send').click(function() {
   var firstFormData  = $('form:eq(0)').serializeArray();
   var fourthFormData = $('form:eq(3)').serializeArray();
   $.ajax({
        url  : '...',
        type : 'post',
        data : firstFormData.concat(fourthFormData)
   }).done(function() {
       // ...
   });
});

Okay, I could not get .serialize() to work with checkbox array from form4 e.g. 

<input type="checkbox" id="model[]">

I tried to grab checked values but could not get them to serialize together with other input :

var vals = []
    $('input:checkbox[name="model[]"]').each(function() {
        if (this.checked) {
            vals.push(this.value);
        }
    });

So I went back and did the simpler thing :

Removed form1, move the text input and the submit button within a <div id="searchbox" style="position:abosulte;top:-100px;left:0px;">My original form1</div> inside form4.

Put a placeholder <div id="placeholder" style="position:relative;"></div> above form2 and 3 where form1 used to be.

Place a javascript above :

$(document).ready(function(){
    $("#searchbox")
    .appendTo("#placeholder");
});

to move the text input and submit button to position them absolute and relative to the placeholder div.

This way I reduced them to 1 form (which is what its intention anyways), does not rely on javascript to manipulate any data, and does not require me to do the tandem serialization on both forms.
