Ajax PHP upload script - php

Question

Where do i put my PHP SQL query, to insert image information to my database?
I tried just before the echo "success"; however it had no effect.
<!-- Upload Button-->
<div id="upload" >Upload File</div><span id="status" ></span>
<!--List Files-->
<ul id="files" ></ul>
PHP handling
<?php
$uploaddir = './uploads/';
$file = $uploaddir . basename($_FILES['uploadfile']['name']);
if (move_uploaded_file($_FILES['uploadfile']['tmp_name'], $file)) {
echo "success";
} else {
echo "error";
}
?>
Javascript section
$(function () {
var btnUpload = $('#upload');
var status = $('#status');
new AjaxUpload(btnUpload, {
action: 'upload-file.php',
//Name of the file input box
name: 'uploadfile',
onSubmit: function (file, ext) {
if (!(ext && /^(jpg|png|jpeg|gif)$/.test(ext))) {
// check for valid file extension
status.text('Only JPG, PNG or GIF files are allowed');
return false;
}
status.text('Uploading...');
},
onComplete: function (file, response) {
//On completion clear the status
status.text('');
//Add uploaded file to list
if (response === "success") {
$('<li></li>').appendTo('#files').html('<img src="./uploads/' + file + '" alt="" /><br />' + file).addClass('success');
} else {
$('<li></li>').appendTo('#files').text(file).addClass('error');
}
}
});
});

The query should be right before success echo, so you have to verify what is returning to you the move_uploaded_file method.
Verify if ./upload/ is the right path and if you have read/write access (0777) on this directory.
Also make sure that you're connected to database:
<?php
$conn = mysql_connect("HOST","USER","PASSWORD");
$db = mysql_select_db("DB_NAME");
$uploaddir = './uploads/';
$file = $uploaddir . basename($_FILES['uploadfile']['name']);
if (move_uploaded_file($_FILES['uploadfile']['tmp_name'], $file)) {
mysql_query("INSERT INTO photos VALUES ('your_values')");
echo "success";
} else {
echo "error";
}
?>
