Blueimp jQuery File Upload Integrated with Database - php

Question

This plugin reads image files on blueimproot/server/php/files on page load. I need to read records from database, and replace 'download' HTML structure with my custom structure. I want to show catalog products, which items are affected by uploading/removing images through this plugin.
I've done this so far:
I changed public function get() { ... } in blueimproot/server/php/upload.class.php to retrieve records from database. This function returns json object.
public function get() {
/* default code of Blueimp
$file_name = isset($_REQUEST['file']) ?
basename(stripslashes($_REQUEST['file'])) : null;
if ($file_name) {
$info = $this->get_file_object($file_name);
} else {
$info = $this->get_file_objects();
}
header('Content-type: application/json');
echo json_encode($info);
*/
include_once('../../../../connection.php');
$id_cat = $_REQUEST['catid'];
$query = "SELECT id, name, price, img_path FROM products WHERE id_cat = $id_cat ORDER BY id";
$prods = mysql_query($query);
$prod_arr = array();
while($prod = mysql_fetch_assoc($prods)) {
$prod_arr[] = $prod;
}
header('Content-type: application/json');
echo json_encode($info);
}
I found that function is called from index.php in blueimproot/server/php:
switch ($_SERVER['REQUEST_METHOD']) {
...
case 'GET':
$upload_handler->get();
break;
...
}
I don't know where the returned json object is processed to show to UI. Have been 2 days and still can't track that function flow. Please help. Thanks.

Answer 1

My suggestion is to open up the Network Tab in Firebug and watch for any GET requests to server/php/index.php. If it happens after a specific event then you'll have a better idea of where you should look.
I did look through the source files and the only GET request I found was in main.js
$('#fileupload').each(function () {
var that = this;
$.getJSON(this.action, function (result) {
if (result && result.length) {
$(that).fileupload('option', 'done')
.call(that, null, {result: result});
}
});
});
}

public function get() {
/*
$file_name = isset($_REQUEST['file']) ?
basename(stripslashes($_REQUEST['file'])) : null;
if ($file_name) {
$info = $this->get_file_object($file_name);
} else {
$info = $this->get_file_objects();
}
header('Content-type: application/json');
echo json_encode($info);
*/
$id_cat = $_REQUEST['catid'];
$query = "SELECT id, name, price, img_path FROM products WHERE id_cat = $id_cat ORDER BY id";
$prods = mysql_query($query);
$prod_arr = array();
while($prod = mysql_fetch_assoc($prods)) {
//$prod_arr[] = $prod;
$file = new stdClass();
$file->name = "";// here image name goes i do not find image name in your select query
$file->size = filesize($prod["img_path"]);// should be complete path
$file->url = $prod["img_path"];// should be relative path (http://localhost/images/234.jpg)
$file->thumbnail_url = $prod["img_path"]; // thumbnail path
$this->delete_type = "DELETE";
$this->delete_url = ""; //here delete url you can delete image from database
array_push($prod_arr,$file);
}
header('Content-type: application/json');
echo json_encode($prod_arr);
}

Following this WIKI: https://github.com/blueimp/jQuery-File-Upload/wiki/Working-with-databases
I setup uploads to be inserted into a database, then i changed my GET function as follows:
public function get() {
$uploads = $this->query_db();
header('Content-type: application/json');
echo json_encode($uploads);
}
and my query_db function as follows:
public function query_db() {
$uploads_array = array();
$select_result = $this->query("SELECT * FROM `uploads` ORDER BY `file_name`") or die(mysql_error());
while($query_results = mysql_fetch_object($select_result))
{
$file = new stdClass();
$file->id = $query_results->id;
$file->name = $query_results->file_name;
$file->size = $query_results->file_size;
$file->type = $query_results->file_type;
$file->url = "http://files.domain.com/".$query_results->file_name;
$file->thumbnail_url = "http://thumbnails.domain.com/".$query_results->file_name;
$file->delete_url = "";
$file->delete_type = "DELETE";
array_push($uploads_array,$file);
}
return $uploads_array;
}
