Jquery.ajax PUT data not parsed by PHP

Question

I am using the Slim PHP Framework and am trying to send FormData using Jquery.ajax() in the following way:

var data = new FormData();
data.append('some_name', 'some_data');
data.append('a_file', $('input[name=the_file_form_field]').get(0).files[0]));

$.ajax({
    url: 'the_destination_url',
    data: data,
    processData: false,
    contentType: false,
    type: 'PUT',
    dataType: 'json',

    success: function(data, textStatus, jqXHR) {
        //Processing result here
    },

    error: function(jqXHR, textStatus, errorThrown) {
        //Processing result here
    }
});

However, I tried the following scenarios:

• Works : Formdata without a file, adding _METHOD=PUT and setting $.ajax to type: POST
• Doesn't work (php receives no PUT data) : Formdata without a file, setting $.ajax to type: PUT
• Doesn't work (method stays POST) : Formdata with a file, adding _METHOD=put and setting $.ajax to type: POST
• Doesn't work (php receives no PUT data) : Formdata with a file, setting $.ajax to type: PUT

Is there anything I'm missing?

the application requires it to use a PUT request and as such a POST request is no possibility.

Answer 1

Just try to send data as an object. eg

data: {'formData' : data},

Your Ajax request should look like

$.ajax({
    url: 'the_destination_url',
    data: {'formData' : data},
    processData: false,
    contentType: false,
    type: 'PUT',
    dataType: 'json',

    success: function(data, textStatus, jqXHR) {
        //Processing result here
    },

    error: function(jqXHR, textStatus, errorThrown) {
        //Processing result here
    }
});

I solved it using the comments from people posting in: https://bugs.php.net/bug.php?id=26004

Apparently PHP silently discards all incoming POST data whenever the post_max_size directive is exceeded.

Aside from post_max_size it's also smart to check the upload_max_filesize directive.

The Best way to get PUT data sent from Ajax JQuery in PHP is:

Send your data Like this in JavaScript:

where mydata is {k1 : "val1" , "k2" : "val2" , }

 $.ajax({
     url: "data.php",
     contentType : "json",
     data : mydata,
     method:"PUT",
     success: function (data) {
         console.log(data);
     },
     error: function (err) {
         console.log(err);
     },
     complete:function (e) {
         console.log(e);
     }
 });

The way to get the data in data.php file is:

parse_str(file_get_contents("php://input"),$putVars);
var_dump( $putVars ); // input from your form
