I'm trying to asynchronously upload a file via javascript in the background. I'm updating our library to use fetch instead of XHR. The XHR request works correctly and the network tab shows the expected response which is currently just a var_dump($_FILES) and a var_dump($_POST).
When I make the same call with fetch for some reason the PHP stops running on the session creation.
I've isolated it down to the line:
$session = new Session;
Here is a cleaned up version of the XHR which returns both of those PHP arrays populated correctly
var request = {},
url = "../../lib/upload.php",
formData = new FormData;
formData.append(
"PHP_SESSION_UPLOAD_PROGRESS", phpSessionKey // upload session key var
);
formData.append(
"uploaded_file", this.file.baseFile // file object from an upload input
);
formData.append(
"pageid", 1234
);
request = new XMLHttpRequest();
request.open("POST", url, true);
request.onreadystatechange = function () {
if (request.readyState === 4 && request.status === 200) {
console.log(responseText);
}
}
request.send(formData);
Here is the comparable fetch, mind you I've looked at headers and everything else which all seem to be identical but I can not figure out why the fetch version exits on that session creation line.
let formData = new FormData(),
phpSessionKey = Uploader.pageid + "_" + this.file.name,
that = this;
formData.append(
"PHP_SESSION_UPLOAD_PROGRESS", phpSessionKey
);
formData.append(
"uploaded_file", this.file.baseFile
);
formData.append(
"pageid", Uploader.pageid
);
fetch('../lib/upload.php', {
method: 'POST',
body: formData
});
This fetch in the network tab returns nothing and by going in and comment then uncommenting lines I've narrowed the issue down to the session creation line in upload.php. I'm honestly just confused about why this is happening at this point, trying to bring out JS standards up has been pretty smooth sailing until now.
EDIT

So I'm trying to call a php method from javascript so I can query a database and get the results into my js functionality. Currently, the 'console.log(output)' that is in my ajax is just outputting:
"array (size=1)
'action' => string 'getResults' (length=10)'"
Not really sure why it's doing this, it should be returning the query result which is just one entry from the database. Anyone have any idea? Any help is welcome! Thanks.
Part of my Javascript file:
function callPHP() {
$.ajax ({
type: "GET",
datatype: "application/json",
url: "BaseClass.php",
data: { action : 'getResults' },
//error: function(err){console.log(err)},
success: function(output) {
console.log(output);
//alert(output);
}
//error, function(err){console.log(err)}
});
}
callPHP();

I think you misunderstand how to ship data between javscript and php.
Your javascript should be posting with $.post() if you want to send an object or array of data.
Your php will recieve json from the javascript. You need to use php's json_decode function on it to make it useful to php.
If you want the output of your php script to be useful to javascript, you need to encode it with php's json_encode function before returning it to the calling script.
http://php.net/manual/en/function.json-decode.php
The output is for echo var_dump($_GET); I'm sure. I can tell because of the output format is a var_dump type. and the success part of your code does not have any output. I mean in this part else { //Decodes data, dont change ... the output has been commented out.
I noticed that you are using MySqli but some methods are MySql api like this part of the code
//if (mysql_num_rows($result) == 1) {
// $obj = mysql_fetch_object($result, 'obResults');
//}
I assume this code is not complete and in debugging phase as I can see many incomplete methods and function calls.
Also try to use prepared statements with place holders for security.
It is a good practice to use ob_clean() before API output as any extra character will destroy the output data and format. However, you will not see errors. There are useful tools for API testing like Browsers Rest Client extensions. The best way for debugging is always debugging tools and frameworks like x-debug.
Do following changes to your code. Hope this helps!

I think it's because of the version of PHP that you are using.
As mentioned in php documentation mysqli_stmt::get_result, this method is supported since PHP 5.3.0.
And it is stated in the user notes section that:
This method requires the mysqlnd driver. Othervise you will get this error: Call to undefined method mysqli_stmt::get_result()
Instead of this function, try using bind_result function.

Check if PATH_INFO is set as this triggers a PHP notice causing invalid json string response. You can also use error_reporting(E_ALL & ~E_NOTICE); to hide notices. See http://php.net/manual/en/function.error-reporting.php

Your script should look like this:
$(document).ready(function() {
$.ajax({
type: "GET",
url: "../server/server.php",// adjust this to be a valid relative URL or an absolute URL
data: {
method: "all"
},
dataType: "json",
success: function(content) {
var table = $.makeTable($.parseJSON(content));
$(table).appendTo("#TableContent");
}
});
});
i have this model function for counting the number of users
public function get_employee_list($role_id) {
$qStr = "SELECT
count(admins.id)
FROM
admins
WHERE
admin_role=".$role_id;
$query = $this->db->query($qStr);
return $query->row_array();
}
and my controller function is like this
public function delete_employee_role_ajax($role_id) {
$objResponse = new xajaxResponse();
$response = $this->employee_model->get_employee_list($role_id);
//print_r($response);
if($response) {
$objResponse->script( "bootbox.alert('$response +users are associated with this role and it cannot be deleted')" );
}
else {
$response = $this->employee_model->delete_employee_role($role_id);
$objResponse->script( "window.location.reload()" );
}
return $objRespons
}
i want to print the value of $response.
You could try encoding it as a JSON structure:
$encodedResponse = json_encode($response);
$objResponse->script("bootbox.alert('$encodedResponse +users are associated...')" );
