The POST action is being passed but POST data is empty after client edit

glenbenson

I need to write the backend in Java (Tomcat) I am using the datatables editor demo code to get up and running . After an edit (save on blur) I need to pass the data to my own code.
To test I'm using a simple php code to look at the data.
Here is that code

<?php
$input_data = $_POST;
// Collect all of the POST data and werite to a file dtepost.txt.
foreach ($_POST as $key => $value) {
     $x = htmlspecialchars($key)." = ".htmlspecialchars($value)."\n";
     file_put_contents("dtepost.txt", $x,FILE_APPEND);
 }
// I return this so it doesnt crash the client just for testing
echo "{\"data\":[{\"DT_RowId\":\"row_29\",\"first_name\":\"Fiona\",\"last_name\":\"Green\",\"position\":\"Chief Operating Officer (COO)\",\"email\":\"f.green@datatables.net\",\"office\":\"San Franciscodsfsdf\",\"extn\":\"2947\",\"age\":\"48\",\"salary\":\"850000\",\"start_date\":\"2010-03-11\"}],\"debug\":[\"xx\"]}";

<?php
>
```
?>


This is the contents of the file dtepost.txt 

data =
action = edit

There is no data received BUT I did get the action.

```js
/*    Here is the chunk of the client code */
var editor; // use a global for the submit and return data rendering in the examples

        $(document).ready(function() {
            editor = new $.fn.dataTable.Editor({
                ajax: {
                    "url": "dte.php",
                    "type": 'POST',
                    success: function(data) {
                        console.log(data);
                    }
                },
                table: "#example",
                fields: [{
                        label: "First name:",
                        name: "first_name"
            }, {
                        label: "Last name:",
                        name: "last_name"
            }, {
                        label: "Position:",
                        name: "position"
            }, {
                        label: "Office:",
                        name: "office"
            }, {
                        label: "Extension:",
                        name: "extn"
            }, {
                        label: "Start date:",
                        name: "start_date",
                        type: "datetime"
            }, {
                        label: "Salary:",
                        name: "salary"
            }
        ]
        
            });

Is the row data passed as a POST from the submitted form or some other way.

data, as posted is an object. htmlspecialchars expects a string - hence the issue.

What you could do is:

$x = print_r($_POST, true);
file_put_contents("dtepost.txt", $x,FILE_APPEND);
// note - no need for the `for` loop

Which uses print_r to dump the value.

Unusual to be writing PHP for a Java backend though ;-).

The client / server data interchange for Editor is documented in the manual, and the examples all show the data submitted / received if you click the last table below the table.
