I have a form with four `<input type='submit'/>` buttons and `action='updateEstado.php'`. Also, I have some jQuery code that launches when I click a button.

```
<!-- CHANGE STATUS MODAL MENU -->

<div class="modal fade" id="change" tabindex="-1" role="dialog" aria-labelledby="change" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">

            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-hidden="true"><span class="glyphicon glyphicon-remove" aria-hidden="true"></span></button>
                <h4 class="modal-title custom_align" id="Heading">CANVIAR ESTAT</h3>    
            </div>

            <form action="updateEstado.php" method="post">  
                <div class="modal-body">
                    <div class=" text-center">

                                <div class="container-fluid">   
                                    <div class="row">
                                        <div class="col-md-12 text-center">
                                            <input type="submit" id="cambiarestado" class="btn btn-modal-estado" style="background-color:YellowGreen; color:white;" value="ACTIVAT">
                                        </div>
                                    </div>

                                    <div class="row">
                                        <div class="col-md-12 text-center">
                                            <input type="submit" id="cambiarestado" class="btn btn-modal-estado" style="background-color:Tomato; color:white;" value="PENDENT MIQUEL ALIMENTACIÓ">          
                                        </div>
                                    </div>

                                    <div class="row ">
                                        <div class="col-md-12 text center">
                                            <input type="submit"  id="cambiarestado" class="btn btn-modal-estado" style="background-color:SkyBlue; color:white;" value="PENDENT ADDCOM">
                                        </div>  
                                    </div>

                                    <div class="row">
                                        <div class="col-md-12 text center">
                                            <input type="submit" id="cambiarestado" class="btn btn-modal-estado" style="background-color:Gray; color:white;" value="DESACTIVAT">
                                        </div>
                                    </div>

                                    <div class="row">
                                        <h5 id='codigosSeleccionados'></h5>
                                    </div>
                                </div>    

                        </div>   
                    </div>
                </form>
            </div>
        </div>
    </div> 
</div>

<script>
    $('#cambiarestado').click(function(){
        event.preventDefault();                     
        // Get the value of the input fields
        var inputvalue = $(this).attr("value");

        // Send Ajax request to updateEstado.php, with value set as 'input' in the POST data
        $.post("updateEstado.php", {estado: "DESACTIVAT", codigo: "38"});

        alert(inputvalue);          
    });
</script>

```

I have updated the jquery code with this new line: `event.preventDefault();`

Now when I launch the updateEstado.php the console show this message:

[![enter image description here](https://i.stack.imgur.com/sHiRo.png)](https://i.stack.imgur.com/sHiRo.png)

If I delete this line: `$.post("updateEstado2.php", {estado: "DESACTIVAT", codigo: "38"});`

The show message disappear. It's clear this is the problem. The solution¿? I do not...
