I need to send an array of java script to php, this is the idea that I have made but it does not work, if you can help solve the problem or find another way to do it I would appreciate it. The idea is to reload the entire page again.
I have problems sending a JSON to a controller via AJAX, the JS alert works and the JSON shows me, but the controller is not receiving the data.
creation of 'actualizar':

var actualizar = new Object();
function myButton_onclick(x,id) {
   if(x.style.backgroundColor=='rgb(255, 114, 144)')
{
    x.style.backgroundColor='rgb(90,237,247)';
     actualizar[id]=1;

}else{
    x.style.backgroundColor='rgb(255, 114, 144)';
     actualizar[id]=0;

}
console.log(actualizar)
return false;
}

view:

$id= array('id' => 'x' );
echo form_open("cursos/guardarmalla",$id);?>
<div align="center"><?php echo form_submit('','Guardar Malla',"class=\"btn btn-success btn-lg\"");?></div>
<?php echo form_close()?>
<script type="text/javascript">
   $(document).ready(function(){
    $('#x').submit(function(){
      var aux = JSON.stringify(actualizar);
      $.ajax({
        type  :'POST',
        url: $(this).attr("action"),
        dataType: "json",
        data   : aux
    });
  alert(aux);

  })
})
</script>

controller:

function guardarmalla(){

    $datos= $this->input->post('aux');
    $deco=json_decode($datos,true);
    echo "Los datos recibidos son".$deco;

}

I regret having the variables in Spanish. I'm from Chile and in stackoverflow in Spanish I had no answer

EDIT

I think the problem is that ajax does not cause the driver function to run

EDIT EDIT

Investigating arrives at the conclusion that AJAX is not necessary, since I want to reload the whole page again, but I do not know how to send an Array or JSON they are the "submit" button to PHP

Answer 1

In your ajax in js you need to correct code:

    $.ajax({
        type  :'POST',
        url: $(this).attr("action"),
        dataType: "json",
        data   : {'aux' : aux}
    });

It corrected structure of json variable

Also instead alert(aux); add return false;. It is prepent of html form submit.
