I am trying to figure out how to send a file that containts things like images to text files, etx from a form submission through ajax to my php file to send into an email. I am trying to format it the way I have my other data in ajax and php email, but I can tell the form stops right away in my ajax. It doesn't even send through to my php, but I am not sure if I have the email part right either.
This is what I tried so far. I tried to delete as much obsolete code as possible, but still include enough to give a good feeling for what I am trying to do.
How can I make this file attach/send into an email from a form through AJAX to my php email
<form action="" autocomplete="on" method="POST" id="project-information-form" enctype="multipart/form-data">
  <input type="text" class="input-borderless" id="project-name" name="name" placeholder="Your Name">
  <input type="email" class="input-borderless" id="project-email" name="email" placeholder="Email Address">
  <input type="number" class="input-borderless" id="project-number" name="phone" placeholder="Phone Number">
  <input type="file" name="file" id="file" class="inputfile" data-multiple-caption="{count} files selected" multiple>
  <label for="file"><span id="file-upload-image"><img src="/icons/white-upload.png" height="25px" width="25px"></span>File Upload</label>
  <input type="submit" id="submit-project" class="submit-project-button" value="Send Project Inquiry">
</form>
AJAX
   $("#submit-project").on("click", function(event) {
     // event.preventDefault();
      var project_name = $("#project-name").val();
      var project_email = $("#project-email").val();
      var project_number = $("#project-number").val();
      var uploaded_file = $("#file").val();
        submitHandler: function(form) {
console.log(form);
          $.ajax({
            url: "email-project.php",
            type: "POST",
            data: {
              "project_name": project_name,
              "project_email": project_email,
              "project_number": project_number,
              "file": project_file
            },
            success: function(data) {
              //console.log(data); // data object will return the response when status code is 200
              if (data == "Error!") {
                alert("Unable to send email!");
                alert(data);
              } else {
              }
            },
