I am trying to send the data of a form to use in php, I made a script in ajax to send the data, I can access POST data normally, the problem is that I can not access the image that is in the same form by placing enctype="multipart / form-data" in form.

AJAX script

<script>
    $(function(){
        var url = 'Chamadas/adicionarAnuncio.php';
        function carregando()
        {
            //$('.loadCadastro').fadeIn('slow');
        }
        $('#formCriarAnuncio').submit(function(){               
            var dados = $(this).serialize();
            $.ajax({
                url:url,
                type: 'POST',
                data: dados,
                beforeSend: carregando,
                success: function(retorno)
                {               
                    if(retorno==1) 
                    { 
                        $('.anuncioFalha').html("");
                    }
                    else if (retorno==2)
                    {
                        $('.anuncioFalha').html("");
                    }
                    else 
                    {   
                        alert("Anuncio registrado com sucesso!");
                        window.location.href ="meusanuncios.php";
                    }
                }
            });
            return false;
        });
    });
 </script>

form

<form enctype="multipart/form-data" name="formCriarAnuncio" method="post" id="formCriarAnuncio">
    <div class="input-field col s12">
        <i class="mdi-communication-email prefix"></i>

To send files multipart with Ajax you need to use FormData . I edited your script with an example of how to do it.

<script>
    $(function(){
        var url = 'Chamadas/adicionarAnuncio.php';
        function carregando()
        {
            //$('.loadCadastro').fadeIn('slow');
        }
        $('#formCriarAnuncio').submit(function(){               
            var dados = new FormData($(this));
            $.ajax({
                url:url,
                type: 'POST',
                data: dados,
                beforeSend: carregando,
                success: function(retorno)
                {               
                    if(retorno==1) 
                    { 
                        $('.anuncioFalha').html("");
                    }
                    else if (retorno==2)
                    {
                        $('.anuncioFalha').html("");
                    }
                    else 
                    {   
                        alert("Anuncio registrado com sucesso!");
                        window.location.href ="meusanuncios.php";
                    }
                }
            });
            return false;
        });
    });
 </script>
