My php script for mailing a form is not working

Question

I am trying to set up a form that will send attachments along with the email content, but I have no idea what I am doing.

I am completely new to PHP, and just learned to do the basic mail form work by, basically, trial and error, along with tutorials on the internet. But, when it came to attachments. Now I am completely at loss. And, although the PHP script supposedly runs, and the file is uploaded, all the operation stops all of a sudden. Neither do I get the messages that should show when the scripts finishes running nor do I get an email with the test message and its attachment.

Can anyone help me, or at least walk me through so I can understand what's my error? My HTML and PHP are as follows:

HTML (Form and title)

<h3 style="padding-left:290px">Consulta de orçamento</h3>
<form id="form" method="post" action="formulario_orcamento.php" style="padding-left:100px" enctype="multipart/form-data">

You probably have PHP errors that you are not seeing, try adding these lines to the top of your php:

error_reporting(E_ALL);
ini_set('display_errors', true);

This code will enable error reporting, which probably will make you see something..

Also, this line: if($_POST['Duvidas'] = "Outras Dúvidas")

is not comparing $_POST['Duvidas'] with "Outras Dúvidas" but is assigning the value "Outras Dúvidas" to $_POST['Duvidas'], which is always true.. Use if($_POST['Duvidas'] == "Outras Dúvidas") instead (note the ==). This might be cause of your problems.
