bad request error in angularjs

var successCallback=function(response) {
if(response.success) {
$log.log(response.data);
alert('fetched courses and percentages successfully');
} else {
}
};
var errorCallback = function(response) {
console.log(response.success);
alert( "failure message: " + JSON.stringify(response));
};
var data = { "mis": 111608059};
// data = JSON.stringify(data),
$http.post('api/stu_course_%.php', data).then(successCallback, errorCallback);
The above code gives the following error:
failure message: {"data":"\n\n400 Bad Request\n\nBad RequestYour browser sent a request that this server could not understand.Apache/2.4.18 (Ubuntu) Server at localhost Port 80\n\n","status":400,"config":{"method":"POST","transformRequest":[null],"transformResponse":[null],"jsonpCallbackParam":"callback","url":"api/stu_course_%.php","data":{"mis":111608059},"headers":{"Accept":"application/json, text/plain, /","Content-Type":"application/json;charset=utf-8"}},"statusText":"Bad Request","xhrStatus":"complete"}

Executing a Php Mysql function from Onclick NO POST

I have a php Mysql interaction and i wish to trigger the Mysql Search through an ONCLICK event.
iv thought about using a JS function or JQ and parsing the ID of selected through JS function but then im unsure as how i would re-execute the php to re-search the database with the new JS Veriable...
The code below is accurate and is what im working with...
How would i re execute the php with the new ID.. Much appreciated..

Does "NO POST" mean "no GET" as well? Otherwise you could put your retrieval script in a different file and call that with jQuery.get or XMLHttpRequest.

How to get a php array index and use it in javascript

I have a PHP script that returns a latitude and longitude from the database.
Then I have a Javascript loop that loops according to the number of rows the PHP query returns and populate my data object with the logitude and latitude at a given index. The challenge now is - how do I get the index without hard coding it?
PHP
$DBhost = 'localhost';
$DBuser = 'root';
$DBpass = '';
$DBname = 'symptoms';
$con = mysqli_connect($DBhost, $DBuser, $DBpass) or die(mysql_error());
mysqli_select_db($con, $DBname);
$query = mysqli_query($con, 'SELECT latitude,longitude FROM markers') or die(mysql_error());
$longArr = array();
$latArr = array();
$count = 0;
while ($row = mysqli_fetch_array($query)) {
$lat = $row['latitude'];
$lon = $row['longitude'];
$latArr[$count] = $lat;
$longArr[$count] = $lon;
++$count;
}
JavaScript
var latArr = [];
var longArr = [];
var markersD = [];
var num = <?php echo $count ?>;
for (var i = 0; i < num; i++) {
var data = {
lat: '<?php echo $latArr[1]?>',
lon: '<?php echo $longArr[1]?>'
}
console.log(data);
}

You have to create json object via php
while($row = mysqli_fetch_array($query))
{
$json[] = array('lat' => $row['latitude'], 'lon' => $row['longitude']);
}
$json_string = json_encode($json);
=== JS ===
var data = <?php echo json_string; ?>;
console.log(data);

You can put all your coords in one array
$coords = array();
while($row = mysqli_fetch_array($query))
{
$coords[] = array(
'latitude' => $row['latitude'],
'longitude' => $row['longitude'],
)
}
and pass it to the js as a JSON object
var data = <?php echo json_encode($coords) ?>;
console.log(data);
All data you need should be available in the javascript

XML not parsing in jQuery

When I try to parse my PHP-generated XML file using the jQuery Feeds plugin, it doesn't do what it's supposed to - loop through the template below and output the XML <title> tag in the place of <!=title!>. Instead, it returns just one instance of the template with nothing in place of <!=title!>.
Nothing is returned in the Chrome JavaScript console.
Strangely, I have a similar PHP-generated XML file that works just fine.
Here's the jQuery I'm using:
$('.feed').feeds({
feeds: {
feed1: 'http://www.comfyshoulderrest.com/scrape.php?id=1' // this one doesn't work
},
//max: 3,
loadingTemplate: '<h1 class="feeds-loader">Loading items...</h1>',
entryTemplate: '<div class="item"><div class="image"><img src="images/tie.jpg" style="width: 100%;"></div>' +
'<div class="text"><ul class="list-inline">' +
'<li><span class="price text-warning"><strong>£7.00</strong></span> <span class="text-muted"><strike>£14.00</strike></span></li>' +
'<li class="text-muted"><strong>Topman</strong></li></ul>' +
'<!=title!>' +
'</div></div>'
});
Here's the code that generates the XML file:
<?php
function scrape($list_url, $shop_name, $photo_location, $photo_url_root, $product_location, $product_url_root, $was_price_location, $now_price_location, $gender, $country) {
header("Content-Type: application/xml; charset=UTF-8");
$xml = new SimpleXMLElement('<rss/>');
$xml->addAttribute("version", "2.0");
$channel = $xml->addChild("channel");
$channel->addChild("product_url", $product_url);
$channel->addChild("shop_name", $shop_name);
$channel->addChild("photo_url", $photo_url);
$channel->addChild("was_price", $was_price);
$channel->addChild("now_price", $now_price);
$html = file_get_contents($list_url);
$doc = new DOMDocument();
libxml_use_internal_errors(TRUE);
if(!empty($html)) {
$doc->loadHTML($html);
libxml_clear_errors(); // remove errors for yucky html
$xpath = new DOMXPath($doc);
/* FIND LINK TO PRODUCT PAGE */
$products = array();
$row = $xpath->query($product_location);
/* Create an array containing products */
if ($row->length > 0)
{
foreach ($row as $location)
{
$product_urls[] = $product_url_root . $location->getAttribute('href');
}
}
$imgs = $xpath->query($photo_location);
/* Create an array containing the image links */
if ($imgs->length > 0)
{
foreach ($imgs as $img)
{
$photo_url[] = $photo_url_root . $img->getAttribute('src');
}
}
$result = array();
/* Create an associative array containing all the above values */
foreach ($product_urls as $i => $product_url)
{
$result = array(
'product_url' => $product_url,
'shop_name' => $shop_name,
'photo_url' => $photo_url[$i]
);
$item = $channel->addChild("item");
$item->addChild("product_url", $result['product_url']);
$item->addChild("shop_name", $result['shop_name']);
$item->addChild("photo_url", $result['photo_url']);
}
//print_r($result);
}
else
{
echo "this is empty";
}
echo $xml->asXML();
}
/* CONNECT TO DATABASE */
$dbhost = "xxx";
$dbname = "xxx";
$dbuser = "xxx";
$dbpass = "xxx";
$con = mysqli_connect("$dbhost", "$dbuser", "$dbpass", "$dbname");
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$id = $_GET['id'];
/* GET FIELDS FROM DATABASE */
$result = mysqli_query($con, "SELECT * FROM scrape WHERE id = '$id'");
while($row = mysqli_fetch_array($result)) {
$list_url = $row['list_url'];
$shop_name = $row['shop_name'];
$photo_location = $row['photo_location'];
$photo_url_root = $row['photo_url_root'];
$product_location = $row['product_location'];
$product_url_root = $row['product_url_root'];
$was_price_location - $row['was_price_location'];
$now_price_location - $row['now_price_location'];
$gender = $row['gender'];
$country = $row['country'];
scrape($list_url, $shop_name, $photo_location, $photo_url_root, $product_location, $product_url_root, $was_price_location, $now_price_location, $gender, $country);
}
mysqli_close($con);
?>
