I have a form where I send data through jQuery AJAX. However, I would also like to send a file. How do I add to my code?
var formData = {
'titulo': $('input[name=titulo]').val(),
'tipo' : $('select[name=tipo]').val(),
'dataa' : $('input[name=data]').val(),
'desc' : $('textarea[name=desc]').val()
};
// process the form
$.ajax({
type : 'POST',
url : 'processar.php',
data : formData,
dataType : 'json',
encode : true
})
You could try something like:
HTML
<h1>jQuery Ajax submit Multipart form</h1>
<form method="POST" enctype="multipart/form-data" id="fileUploadForm">
<input type="text" name="extraField"/><br/><br/>
<input type="file" name="files"/><br/><br/>
<input type="file" name="files"/><br/><br/>
<input type="submit" value="Submit" id="btnSubmit"/>
</form>
<h1>Ajax Post Result</h1>
<span id="result"></span>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.4/jquery.min.js"></script></body></html>JS
$(document).ready(function(){$("#btnSubmit").click(function (event) {
//stop submit the form, we will post it manually.
event.preventDefault();
// Get form
var form = $('#fileUploadForm')[0];
// Create an FormData object
var data = new FormData(form);
// If you want to add an extra field for the FormData
data.append("CustomField", "This is some extra data, testing");
// disabled the submit button
$("#btnSubmit").prop("disabled", true);
$.ajax({
type: "POST",
enctype: 'multipart/form-data',
url: "/api/upload/multi",
data: data,
processData: false,
contentType: false,
cache: false,
timeout: 600000,
success: function (data) {
$("#result").text(data);
console.log("SUCCESS : ", data);
$("#btnSubmit").prop("disabled", false);
},
error: function (e) {
$("#result").text(e.responseText);
console.log("ERROR : ", e);
$("#btnSubmit").prop("disabled", false);
}
});
});
});

The secret here is to use new FormData () to "retrieve form data" and set the processData parameter of the ajax request to FALSE >.
