when i want order column similarity from Levenshtein calculation result but i get error in ajax_list response
Type: mysqli_sql_exception
Message: Unknown column 'similarity' in 'order clause'
i have code in controller codeigniter3 like this
public function ajax_list()
{
$list = $this->article->get_datatables();
$data = array();
$no = $_POST['start'];
$searchinput=$_POST['search']['value'];
foreach ($list as $article) {
$no++;
$row = array();
$row[] = $no;
$row[] = $article->title;
$text1 = $row[2];
$text2 = $searchinput;
$similarity = levenshtein($text1, $text2) / max(strlen($text1), strlen($text2));
$result_similarity=(1 - $similarity) * 100;
$row[] = $result_similarity;
$data[] = $row;
}
$output = array(
"draw" => $_POST['draw'],
"recordsTotal" => $this->article->count_all(),
"recordsFiltered" => $this->article->count_filtered(),
"data" => $data,
);
//output to json format
echo json_encode($output);
}
and i have code in models like this
var $table = 'article';
var $column_order = array(null,'title','result_similarity'); //set column field database for datatable orderable
var $column_search = array('title'); //set column field database for datatable searchable
var $order = array('title' => 'asc'); // default order

how to get data in controller using codeigniter 3 framework
i have code in ci3 controller like this:
public function ajax_list()
{
$list = $this->thesis_title->get_datatables();
$data = array();
$no = $_POST['start'];
$text1 = "Detection of student assignments based on document.";
$text2 ="test program simple levenshtein distance";
$distance=levenshtein($text1, $text2);
foreach ($list as $text_title) {
$no++;
$row = array();
$row[] = $no;
$row[] = $title_text->id_title;
$row[] = $title_text->title;
$row[] = $distance;
$data[] = $row;
}
$output = array(
"draw" => $_POST['draw'],
"recordsTotal" => $this->title_thesis->count_all(),
"recordsFiltered" => $this->title_thesis->count_filtered(),
"data" => $data,
);
//output to json format
echo json_encode($output);
}
what I want to do is retrieve the title data from the database and assign the value to the $text1 variable
Is it possible to repeat a function when it has finished. For Example: I have a function for export mysql to json file with a limit of 100 data. if it is successful create a json file with 100 data. Then it will repeat the same function to create json file 100 more data (no duplicate data) until the data runs out.
my code for generate json file :
$results = $db->SELECT()
->FROM( array( 'MM'=>'M_MEMBER'),
array( 'MEMBER_ID' => 'MM.MEMBER_ID',
'FIRST_NAME' => 'MM.FIRST_NAME',
'LAST_NAME' => 'MM.LAST_NAME',
'MEMBER_GROUP' => 'MM.MEMBER_GROUP',
'MEMBER_GROUP1' => 'MM.MEMBER_GROUP1',
'PHONE_NUMBER' => 'MM.PHONE_NUMBER',
'MEMBERSHIP' => 'MM.MEMBERSHIP',
'UPLOAD_DATE' => 'MM.UPLOAD_DATE',
'STATUS' => 'MM.STATUS'
)
)
->WHERE('DATE(MM.UPLOAD_DATE) = CURDATE()')
->WHERE('SYNC_FLAG = ?','N')
->LIMIT(100)
->QUERY()->FETCHALL();
if (!empty($results) && $results['SYNC_FLAG'] != 'Y')
{
$counter = formatNbr($counterFile);
$data = array();
foreach ($results as $key=>$row) {
$data[$key] = $row;
$data[$key]['_id'] = (string) Application_Helper_General::generateIdJsonFile();
$queryUdateMemberFlag = 'UPDATE M_MEMBER SET SYNC_FLAG = "Y" WHERE MEMBER_ID = '.$row['MEMBER_ID'].'';
$db->query($queryUdateMemberFlag);
}
$out = array_values($data);
$jsonAr = json_encode($out);
$json = substr($jsonAr, 1, -1);
$jsonData = preg_replace('/[\x00-\x1F\x80-\xFF]/', '', $json);
$file = $store_path_pos.'dataMember_'.date('Y-m-d').'_'.$counter.'.json';
$createJson = file_put_contents($file, $jsonData);
if($createJson){
echo "Create Json File Success In :".$file;
}else{
echo "Create Json Failed";
}
}
the code can only generate a json file once, how can it be repeated after generating a successful json file
note: I added a flag for each successful data generated json file
You can extract your codes to a function and use the function in the loop.
Example:
function exporter($limit = 100)
{
$results = $db->SELECT()
->FROM( array( 'MM'=>'M_MEMBER'),
array( 'MEMBER_ID' => 'MM.MEMBER_ID',
'FIRST_NAME' => 'MM.FIRST_NAME',
'LAST_NAME' => 'MM.LAST_NAME',
'MEMBER_GROUP' => 'MM.MEMBER_GROUP',
'MEMBER_GROUP1' => 'MM.MEMBER_GROUP1',
'PHONE_NUMBER' => 'MM.PHONE_NUMBER',
'MEMBERSHIP' => 'MM.MEMBERSHIP',
'UPLOAD_DATE' => 'MM.UPLOAD_DATE',
'STATUS' => 'MM.STATUS'
)
)
->WHERE('DATE(MM.UPLOAD_DATE) = CURDATE()')
->WHERE('SYNC_FLAG = ?','N')
->LIMIT($limit)
->QUERY()->FETCHALL();
if (!empty($results) && $results['SYNC_FLAG'] != 'Y')
{
$counter = formatNbr($counterFile);
$data = array();
foreach ($results as $key=>$row) {
$data[$key] = $row;
$data[$key]['_id'] = (string) Application_Helper_General::generateIdJsonFile();
$queryUdateMemberFlag = 'UPDATE M_MEMBER SET SYNC_FLAG = "Y" WHERE MEMBER_ID = '.$row['MEMBER_ID'].'';
$db->query($queryUdateMemberFlag);
}
$out = array_values($data);
$jsonAr = json_encode($out);
$json = substr($jsonAr, 1, -1);
$jsonData = preg_replace('/[\x00-\x1F\x80-\xFF]/', '', $json);
$file = $store_path_pos.'dataMember_'.date('Y-m-d').'_'.$counter.'.json';
$createJson = file_put_contents($file, $jsonData);
if($createJson) {
echo "Create Json File Success In :".$file;
} else {
echo "Create Json Failed";
}
}
$numberOfRows = 10000; # use the count query here
$limit = 100;
while($numberOfRows > 0) {
exporter($limit);
$numberOfRows -= $limit;
}
Also, you can call your function in your function recursively (https://www.w3schools.blog/php-recursive-functions)
Putting the existing code in a loop seems like the obvious answer here.
do {
$results = $db
->SELECT()
->FROM(
['MM'=>'M_MEMBER'],
[
'MEMBER_ID' => 'MM.MEMBER_ID',
'FIRST_NAME' => 'MM.FIRST_NAME',
'LAST_NAME' => 'MM.LAST_NAME',
'MEMBER_GROUP' => 'MM.MEMBER_GROUP',
'MEMBER_GROUP1' => 'MM.MEMBER_GROUP1',
'PHONE_NUMBER' => 'MM.PHONE_NUMBER',
'MEMBERSHIP' => 'MM.MEMBERSHIP',
'UPLOAD_DATE' => 'MM.UPLOAD_DATE',
'STATUS' => 'MM.STATUS',
]
)
->WHERE('DATE(MM.UPLOAD_DATE) = CURDATE()')
->WHERE('SYNC_FLAG = ?','N')
->LIMIT(100)
->QUERY()
->FETCHALL();
if (count($results) === 0) {
break;
}
$data = [];
foreach ($results as $row) {
$row['_id'] = (string) Application_Helper_General::generateIdJsonFile();
$data[] = $row;
//
// this is UNSAFE and inefficient, use a prepared statement if possible
//
$queryUdateMemberFlag = 'UPDATE M_MEMBER SET SYNC_FLAG = "Y" WHERE MEMBER_ID = '.$row['MEMBER_ID'].'';
$db->query($queryUdateMemberFlag);
}
$json = json_encode($out);
$filename = sprintf(
"%sdataMember_%s_%s.json",
$store_path_pos,
date("Y-m-d"),
formatNbr($counterFile)
);
if ($json && file_put_contents($filename, $json)) {
echo "Create Json File Success In $file";
} else {
echo "Create Json Failed";
}
} while (true);
I fixed a few inefficiencies in your code; I have no idea what DB library you're using but as a rule you should never inject variables into an SQL query. It's likely safe in this context, but if your library allows you should prepare the statement outside the loop and execute it inside the loop for better performance.
I want to send nested JSON array.Which contain following format.
${"posts":[{
"abc":"123",
"xyz":"123",
"pro":[{
"name":"Brinjal",
"qty":"500 gms"
},
{
"name":"Brinjal",
"qty":"500 gms"
}]
}]
}
Here is my php code:
$rows = $stmt->fetchAll();
if ($rows) {
$order["posts"] = array();
foreach ($rows as $row) {
$post = array();
$post["order_id"] = $row["order_id"];
$post["order_totalamount"] = $row["order_totalamount"];
$post["address"] = $row["address"];
$post["pincode"] = $row["pincode"];
$post["delivery_timeslot"] = $row["delivery_timeslot"];
$post["order_date"] = $row["order_date"];
$query1= "query";
$rows1 = $stmt->fetchAll();
if ($rows1) {
foreach ($rows1 as $row1) {
$query2= "query";
$rows2 = $stmt->fetchAll();
$post["product"] = array();
if ($rows2) {
$products = array();
foreach ($rows2 as $row2) {
$products["product_name"]=$row2["product_name"];
$products["prod_qty"] = $row2["product_minquantity"];
}
array_push($post["product"],$products);
echo json_encode($products);
}
}
}
array_push($order["posts"], $post);
}
echo json_encode($order);
}
From above code I got result:
$ {"posts":
[{
"order_id":"18",
"order_totalamount":"40",
"address":"2, Chetan Society, Vadodara",
"pincode":"390023",
"delivery_timeslot":"Zone wise delivery",
"order_date":"2016-03-18 17:50:53",
"product":[{"product_name":"Brinjal","prod_qty":"500 gms"}]
}]
}
But my actual product array is:
${"product_name":"Banana","prod_qty":"1 Kg"}{"product_name":"Brinjal","prod_qty":"500 gms"}
Kindly help out. I am stuck on it. tried a lot but did not get success.
In
foreach ($rows2 as $row2) {
$products["product_name"]=$row2["product_name"];
$products["prod_qty"] = $row2["product_minquantity"];
}
You overwrite $products["product_name"]and $products["prod_qty"] with the values of the last $row2.
The line {"product_name":"Banana","prod_qty":"1 Kg"}{"product_name":"Brinjal","prod_qty":"500 gms"} actually consists of two echo's:
{"product_name":"Banana","prod_qty":"1 Kg"}
{"product_name":"Brinjal","prod_qty":"500 gms"}
But you don't see the difference. I suggest echoing a string in-between them or use something like var_dump() to see how many values you're echoing.
You should do something like:
for ($i = 0; $i < count($rows2); $i++) {
$products[$i]["product_name"]=$rows2[$i]["product_name"];
$products[$i]["prod_qty"] = $rows2[$i]["product_minquantity"];
}
This will result in: [{"product_name":"Banana","prod_qty":"1 Kg"},{"product_name":"Brinjal","prod_qty":"500 gms"}]
FYI $array[] = has the same rsults as array_push(), but had less overhead of calling array_push().
EDIT:
Below a complete example since it doesn't seem to workout for you:
//Demo $order
$order = array (
'posts' =>
array (
0 =>
array (
'order_id' => '18',
'order_totalamount' => '40',
'address' => '2, Chetan Society, Vadodara',
'pincode' => '390023',
'delivery_timeslot' => 'Zone wise delivery',
'order_date' => '2016-03-18 17:50:53',
),
),
);
//Demo $rows2
$rows2 = array(
array(
'product_name' => 'banana',
'product_minquantity' => '1 Kg'
),
array(
'product_name' => 'Brinjal',
'product_minquantity' => '500 gms'
)
);
$post['product'] = array();
if ($rows2) {
$products = array();
for ($i = 0; $i < count($rows2); $i++) {
$products[$i]['product_name'] = $rows2[$i]['product_name'];
$products[$i]['prod_qty'] = $rows2[$i]['product_minquantity'];
}
$post['product'] = $products;
echo json_encode($products); //[{"product_name":"banana","prod_qty":"1 Kg"},{"product_name":"Brinjal","prod_qty":"500 gms"}]
}
//$order['posts'][] = $post;
$order['posts'][0] = $order['posts'][0] + $post;
//In this example I only have 1 item in $order['posts'] so I know to add to key 0.
//In your case you need to know which key of $rows1 you need to do the adding.
//Change the foreach loop of $rows to a for loop as well so you can define your own keynames ($i).
echo '<br>==================================================================<br>';
echo json_encode($order);
/*

I ma using codeigniter to generate some html options,but i only get one result,first result from the table.
This is my controller
public function edit_event($id = 0){
$id = $this->uri->segment(3);
$current_id = $this->ion_auth->get_user_id();
$data['data'] = $this->as->the_event_edit($id);
$data['groups'] = $this->as->the_groups_list($current_id);
$this->load->view('editevent',$data);
}
This is my model
public function the_groups_list($current_id){
$query = $this->db->get_where('all_groups', array('group_owner' => $current_id));
foreach ($query->result() as $row)
{
$data = array(
'group_title' => $row->group_title,
'group_name' => $row->group_name,
'group_owner' => $row->group_owner
);
return $data;
}
}
This is the other model
public function as_event_edit($id){
$query = $this->db->get_where('all_scheduled_messages', array('id' => $id));
foreach ($query->result() as $row)
{
$data = array(
'as_title' => $row->as_title,
'as_event_name' => $row->as_event_name,
'as_owner' => $row->as_owner,
'as_type' => $row->as_type,
'as_target_dataset' => $row->as_target_dataset,
'as_timestamp' => $row->as_timestamp,
'as_time' => $row->as_time,
'as_day' => $row->as_day
);
return $data;
}
}
I am then using $groups['group_title'] in view and only the first group title gets displayed even though i have like 4 group titles from the other rows.
How can i return and pass an array that i can then to the view so as to use foreach to iterate and display the group titles?.
In your model you're not creating a multi-dimensional array. You need to add keys either using a counter:
$data = array();
$i=0;
foreach ($query->result() as $row){
$data[$i]['as_title'] = $row->as_title;
$data[$i]['as_event_name'] = $row->as_event_name;
$data[$i]['as_owner'] = $row->as_owner;
$data[$i]['as_type'] = $row->as_type;
$data[$i]['as_target_dataset'] = $row->as_target_dataset;
$data[$i]['as_timestamp'] = $row->as_timestamp;
$data[$i]['as_time'] = $row->as_time;
$data[$i]['as_day'] = $row->as_day;
$i++;
);
return $data;
or use the key of the incoming array
$data = array();
foreach ($query->result() as $id => $row){
$data[$id]['as_title'] = $row->as_title;
$data[$id]['as_event_name'] = $row->as_event_name;
$data[$id]['as_owner'] = $row->as_owner;
$data[$id]['as_type'] = $row->as_type;
$data[$id]['as_target_dataset'] = $row->as_target_dataset;
$data[$id]['as_timestamp'] = $row->as_timestamp;
$data[$id]['as_time'] = $row->as_time;
$data[$id]['as_day'] = $row->as_day;
);
return $data;
Change the model from $data = to $data[] = to insert each row and not only one.
In your view loop over the groups, like so:
foreach ($data as $group) {
echo "Title" . $groups['group_title'];
}
RTM: Adding Dynamic Data to the View
In the controller: rename your $data['data'] to $data['event']
$data['event'] = $this->as->the_event_edit($id);
$data['groups'] = $this->as->the_groups_list($current_id);
$this->load->view('editevent',$data);
In your view:
foreach ($event as $items) {
var_dump($items);
}
foreach ($groups as $group) {
var_dump($group);
}
Hi all' I have a page into PHP where I retrieve XML data from a server and I want to store this data into an array.
This is my code:
foreach ($xml->DATA as $entry){
foreach ($entry->HOTEL_DATA as $entry2){
$id = (string)$entry2->attributes()->HOTEL_CODE;
$hotel_array2 = array();
$hotel_array2['id'] = $entry2->ID;
$hotel_array2['name'] = utf8_decode($entry2->HOTEL_NAME);
$i=0;
foreach($entry2->ROOM_DATA as $room){
$room_array = array();
$room_array['id'] = (string)$room->attributes()->CCHARGES_CODE;
$hotel_array2['rooms'][$i] = array($room_array);
$i++;
}
array_push($hotel_array, $hotel_array2);
}
}
In this mode I have the array hotel_array which all hotel with rooms.
The problem is that: into my XML I can have multiple hotel with same ID (the same hotel) with same information but different rooms.
If I have an hotel that I have already inserted into my hotel_array I don't want to insert a new array inside it but I only want to take its rooms array and insert into the exisiting hotel.
Example now my situation is that:
hotel_array{
[0]{
id = 1,
name = 'test'
rooms{
id = 1
}
}
[0]{
id = 2,
name = 'test2'
rooms{
id = 100
}
}
[0]{
id = 1,
name = 'test'
rooms{
id = 30
}
}
}
I'd like to have this result instead:
hotel_array{
[0]{
id = 1,
name = 'test'
rooms{
[0]{
id = 1
}
[1]{
id = 30
}
}
}
[0]{
id = 2,
name = 'test2'
rooms{
id = 100
}
}
}
How to create an array like this?
Thanks
first thing is it helps to keep the hotel id as the index on hotel_array when your creating it.
foreach ($xml->DATA as $entry){
foreach ($entry->HOTEL_DATA as $entry2){
$id = (string)$entry2->attributes()->HOTEL_CODE;
$hotel_array2 = array();
$hotel_array2['id'] = $entry2->ID;
$hotel_array2['name'] = utf8_decode($entry2->HOTEL_NAME);
$i=0;
foreach($entry2->ROOM_DATA as $room){
$room_array = array();
$room_array['id'] = (string)$room->attributes()->CCHARGES_CODE;
$hotel_array2['rooms'][$i] = array($room_array);
$i++;
}
if (!isset($hotel_array[$hotel_array2['id']])) {
$hotel_array[$hotel_array2['id']] = $hotel_array2;
} else {
$hotel_array[$hotel_array2['id']]['rooms'] = array_merge($hotel_array[$hotel_array2['id']]['rooms'], $hotel_array2['rooms']);
}
}
}
Whilst this is the similar answer to DevZer0 (+1), there is also quite a bit that can be done to simplify your workings... there is no need to use array_merge for one, or be specific about $i within your rooms array.
$hotels = array();
foreach ($xml->DATA as $entry){
foreach ($entry->HOTEL_DATA as $entry2){
$id = (string) $entry2->attributes()->HOTEL_CODE;
if ( empty($hotels[$id]) ) {
$hotels[$id] = array(
'id' => $id,
'name' => utf8_decode($entry2->HOTEL_NAME),
'rooms' => array(),
);
}
foreach($entry2->ROOM_DATA as $room){
$hotels[$id]['rooms'][] = array(
'id' => (string) $room->attributes()->CCHARGES_CODE;
);
}
}
}
Just in case it helps...
And this :)
$hotel_array = array();
foreach ($xml->DATA as $entry)
{
foreach ($entry->HOTEL_DATA as $entry2)
{
$hotel_code = (string) $entry2->attributes()->HOTEL_CODE;
if (false === isset($hotel_array[$hotel_code]))
{
$hotel = array(
'id' => $entry2->ID,
'code' => $hotel_code,
'name' => utf8_decode($entry2->HOTEL_NAME)
);
foreach($entry2->ROOM_DATA as $room)
{
$hotel['rooms'][] = array(
'id' => (string)$room->attributes()->CCHARGES_CODE,
);
}
$hotel_array[$hotel_code] = $hotel;
}
}
}
