504 Gateway timeout when sending Ajax Post to PHP file - php

Question

I am having an issue where i get a timeout if i run a certain php script with parameters sent from a Jquery Ajax reequest. However if i simply run this script with no parameters I.E just run it on its own its fine.
The php file the Ajax request is in is noteContent.php
noteContent.php:
<script type="text/javascript">
// Submit generalNote to the database
function submitNoteText()
{
var noteid = <?php if(isset($_POST['noteid'])){ echo $_POST['noteid'];} ?>;
var notetext = $("#ta1").val();
var dataString = 'noteid1=' + noteid + '&notetext1=' + notetext;
if(noteid == ''||notetext == '')
{
alert("NoteID or Text is blank");
}
else
{
$.ajax({
type: "POST",
url: "submitNoteText.php",
dataType: 'json',
data: dataString,
cache: false,
success: function(result){
alert("Success");
}
});
}
return false;
};
</script>
The script its trying to run
submitNoteText.php:
<?php include 'connectionDetails.php'; ?>
<?php
if (isset($_POST['noteid1'], $_POST['notetext1']))
{
var_dump($_POST['notetext1']);
$noteid2 = $_POST['noteid1'];
$notetext2 = $_POST['notetext1'];
$stmt = "UPDATE Notes SET Note = '?' WHERE NoteID = ?";
$params = array($noteid2, $notetext2);
$stmt = sqlsrv_query($conn, $stmt, $params);
if ($stmt === false)
{
die( print_r(sqlsrv_errors(), true));
}
}
else
{
echo "No Data";
}
?>
they are all connected with an include to
connectionDetails.php(which has never returned an error before):
<?php
$myServer = "Test";
$connectionInfo = array('Database' => 'Test', 'UID' => 'Test', 'PWD' => 'test');
//connection to the database
$conn = sqlsrv_connect($myServer, $connectionInfo)
or die("Couldn't connect to SQL Server on $myServer");
//Test connection to server
// if ($conn)
// {
// echo "connection successful"; # code...
// }
?>
<?php
//Defining my queries
$getNotes = "SELECT NoteID, NoteName, Note FROM Notes ORDER BY NoteName ASC";
$getTemplateNotes = "SELECT TemplateNoteID, TemplateNoteName, TemplateNote FROM TemplateNotes ORDER BY TemplateNoteName ASC";
$getReplaceVariables = "SELECT ReplaceVariableID, ReplaceVariableName, ReplaceVariableNote FROM ReplaceVariables ORDER BY ReplaceVariableName ASC";
$resultNotes = sqlsrv_query($conn, $getNotes);
$resultTemplate = sqlsrv_query($conn, $getTemplateNotes);
$resultVariables = sqlsrv_query($conn, $getReplaceVariables);
if( $resultNotes === false)
{
die( print_r( sqlsrv_errors(), true) );
}
if( $resultTemplate === false)
{
die( print_r( sqlsrv_errors(), true) );
}
if( $resultVariables === false)
{
die( print_r( sqlsrv_errors(), true) );
}
?>
When i click the button to run the request i get this:
All the text to be submitted is in the params:

Ajax data parameter should be an array :
$.ajax({
type: 'POST',
url: "your urls",
data: {
id: youridval,
anothervar: anothervalvalue
},
beforeSend: function() {
},
complete: function() {
},
success: function(_result) {
}
});
