I have in gridview
[
'value' => function($data){
$sum = '';
foreach ($data->orderInfo as $request){
$str = ($request->order_items_offer_name);
$sum .= ($str);
}
return implode(',',array($sum)) ;
}],
But there is no comma between data.
Try This:
[
'value' => function($data){
$sum = array();
foreach ($data->orderInfo as $request){
$sum[] = $request->order_items_offer_name;
}
return implode(',',$sum);
}],

The code works fine like this. no problem with toArray
$restaurants = Restorant::where(['active'=>1])->orderBy('id', 'desc')->limit(10)->get();
$data = [];
$item = [];
foreach ($restaurants as $rest_key => $rest_value) {
$item = $rest_value->toArray();
$item["ratings"] = [];
$item["time_to_prepare_order_in_minutes"] = [];
$ratings = DB::table('ratings')->where('rateable_id', '=', $rest_value->id)->get();
foreach ($ratings as $rating_key => $ratings_value) {
$item["ratings"][] = [
"sub_id" => $ratings_value->id,
"rating" => $ratings_value->rating,
];
}
$configs = DB::table('configs')->where('key','=','time_to_prepare_order_in_minutes')->where('model_id','=',$rest_value->id)->first();
$item["time_to_prepare_order_in_minutes"] = $configs->value;
$data[] = $item;
}
return response()->json([
'data' => $data,
'status' => true
]);
But I don't know how to do this when I use join. I also did this logic. How can I do this better? My aim is to tire the server as little as possible while retrieving data in json format. I tried to do it with DB->with option but it gave different errors.
$restaurants = DB::table('companies')->select('companies.*', 'configs.key', 'configs.value')->leftJoin('configs', 'configs.model_id', '=', 'companies.id')->where('configs.key', '=', 'time_to_prepare_order_in_minutes')->where('companies.active', '=', 1)->orderBy('companies.id', 'desc')->limit(10)->get();
$columns = Schema::getColumnListing('companies');
$data = [];
$item = [];
foreach ($restaurants as $rest_key => $rest_value) {
foreach ($columns as $col_key => $col_value) {
$cKey = $columns[$col_key];
$item[$cKey] = $rest_value->$cKey;
}
$item["ratings"] = [];
$ratings = DB::table('ratings')->where('rateable_id', '=', $rest_value->id)->get();
foreach ($ratings as $rating_key => $ratings_value) {
$item["ratings"][] = [
"sub_id" => $ratings_value->id,
"rating" => $ratings_value->rating,
];
}
$data[] = $item;
}
return response()->json([
'data' => $data,
'status' => true
]);
I found the source of the problem. The -> sign solved my problem.
$data = [];
$item = [];
foreach ($cityRestaurants as $city_key => $city_value) {
$item = $city_value;
$item->ratings = [];
$ratings = DB::table('ratings')->where('rateable_id', '=', $city_value->id)->get();
foreach ($ratings as $rating_key => $ratings_value) {
$item->ratings[] = [
"sub_id" => $ratings_value->id,
"rating" => $ratings_value->rating,
];
}
$configs = DB::table('configs')->where('key','=','time_to_prepare_order_in_minutes')->where('model_id','=',$city_value->id)->first();
$item->time_to_prepare_order_in_minutes = $configs->value;
$data[] = $item;
}
I have created a custom restful API endpoint in WordPress which returns the JSON with the only required fields.
So with this one when I go to the example.com/wp-json/wl/posts, it returns 5 posts as I have limited the number of the posts.
function wl_posts() {
$args = [
'numberposts' => 99999,
'post_type' => 'post'
];
$posts = get_posts($args);
$data = [];
$i = 0;
foreach($posts as $post) {
$data[$i]['id'] = $post->ID;
$data[$i]['title'] = $post->post_title;
$data[$i]['content'] = $post->post_content;
$data[$i]['slug'] = $post->post_name;
$data[$i]['featured_image']['thumbnail'] = get_the_post_thumbnail_url($post->ID, 'thumbnail');
$i++;
}
return $data;
}
add_action('rest_api_init', function() {
register_rest_route('wl/v1', 'posts', [
'methods' => 'GET',
'callback' => 'wl_posts',
]);
});
But I also want to add the pagination, so if I add ?page=2 , it should return another 5 posts.
How can that be archived?
When visiting /?rest_route=/ or /wp-json/wp/v2/pages you can drill down into ie. wp/v2/pages/endpoints/0/args then check with page and per_page
curl http://YOUR-SITE/wp-json/wl/v1/posts/?per_page=1&page=2
Publish arguments for reference
We can define and publish these as arguments. This is not required but they are now in line with posts and pages
add_action('rest_api_init', function() {
register_rest_route('wl/v1', 'posts', [
'methods' => 'GET',
'callback' => 'wl_posts',
'args' => [
'page' => [
'description' => 'Current page',
'type' => "integer",
],
'per_page' => [
'description' => 'Items per page',
'type' => "integer",
]
],
]);
});
Fetch arguments
As get_posts has its own logic and it uses WP_Query in the end let's use WP_Query for the better.
function wl_posts() {
$args = [];
if (isset($_REQUEST['per_page'])) {
$args['posts_per_page'] = (int) $_REQUEST['per_page'];
}
if (isset($_REQUEST['page'])) {
$args['page'] = (int) $_REQUEST['page'];
}
$args['post_type'] = 'post';
$get_posts = new WP_Query;
$posts= $get_posts->query( $args );
$data = [];
$i = 0;
foreach($posts as $post) {
$data[$i]['id'] = $post->ID;
$data[$i]['title'] = $post->post_title;
$data[$i]['content'] = $post->post_content;
$data[$i]['slug'] = $post->post_name;
$data[$i]['featured_image']['thumbnail'] =
get_the_post_thumbnail_url($post->ID, 'thumbnail');
$i++;
}
return $data;
}
I am still on the process of learning Yii 2 framework. I was able to create a form that uploads excel file then save to database using phpexcel. I want to enhance it in a way that the data from the uploaded excel will be displayed on a table in view so the user can check the data if they are the same with the excel file. After checking, the user will have two options whether CANCEL or CONTINUE.
Here is my controller method to read file and save:
public function importExcel($model, $readFile, $dir)
{
try {
$readFileType = \PHPExcel_IOFactory::identify($readFile);
$objReader = \PHPExcel_IOFactory::createReader($readFileType);
$objPHPExcel = $objReader->load($readFile);
}
catch(Exception $e) {
die('Error reading data from excel file.');
}
$sheet = $objPHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow();
$highestCol = $sheet->getHighestColumn();
for($row = 9; $row <= $highestRow; $row++) {
$rowData = $sheet->rangeToArray('A'. $row . ':' . $highestCol . $row, NULL, TRUE, FALSE);
$objPHPExcel->getActiveSheet()
->getStyle('A'. $row . ':' . $highestCol . $row)
->getNumberFormat()->setFormatCode('0000');
// ->setFormatCode( \PHPExcel_Style_NumberFormat::FORMAT_TEXT );
if($row == 9) {
continue;
}
$document = new Document();
$document->type_id = ($rowData[0][0] == 'Ordinance' ? 1 : 2);
$document->no = $rowData[0][1];
$document->series = $rowData[0][2];
$document->title = $rowData[0][3];
$document->author = $rowData[0][5];
$document->date_approved = date('Y-m-d', strtotime($rowData[0][8].' '.$rowData[0][9].' '.$rowData[0][10]));
$document->region_c = $model->region_c;
$document->province_c = $model->province_c;
$document->citymun_c = $model->citymun_c;
$document->catParent = 1;
$document->category_id = 1;
$document->file_url = $dir . '/unzip/' . $rowData[0][13];
$document->save();
}
}
I did this and it worked.
try {
$readFileType = \PHPExcel_IOFactory::identify($readFile);
$objReader = \PHPExcel_IOFactory::createReader($readFileType);
$objPHPExcel = $objReader->load($readFile);
}
catch(Exception $e) {
die('Error reading data from excel file.');
}
$sheet = $objPHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow();
$highestCol = $sheet->getHighestColumn();
for($row = 9; $row <= $highestRow; $row++) {
$rowData = $sheet->rangeToArray('A'. $row . ':' . $highestCol . $row, NULL, TRUE, FALSE);
$objPHPExcel->getActiveSheet()
->getStyle('A'. $row . ':' . $highestCol . $row)
->getNumberFormat()->setFormatCode('0000');
if($row == 9) {
continue;
}
$data[] = array(
'type' => $rowData[0][0],
'no' => $rowData[0][1],
'series' => $rowData[0][2],
'title' => $rowData[0][3],
'author' => $rowData[0][5],
'dateapproved' => date('Y-m-d', strtotime($rowData[0][8].' '.$rowData[0][9].' '.$rowData[0][10])),
'file' => $rowData[0][13]
);
}
$dataProvider = new ArrayDataProvider([
'allModels' => $data,
'pagination' => [
'pageSize' => 10,
],
]);
return $this->render('display', [
'dataProvider' => $dataProvider,
]);
}
If your rowData contain the data and is an array of the row read form excel you can do this
$provider = new ArrayDataProvider([
'allModels' => $rowData,
'pagination' => [
'pageSize' => 10,
],
]);
return $this->render('your:view', [
'provider' => $provider,
]);
and in your grdiView
<?= GridView::widget([
'dataProvider' => $provider,
......
in app\tmp\cache\models there is a file called:

Can I convert this (serialized php?) to SQL and recreate my table, if so how? Many thanks in advance.
In PHP create a file:
<?php
class AppSchema extends CakeSchema {
public function before($event = array()) {
return true;
}
public function after($event = array()) {
}
$dir = 'files/';
$files = [
'table_names' => 'myapp_cake_model_default_mydb_tablenames',
];
foreach ($files as $table => $file){
$content = file(realpath( $dir.$file ));
$content = unserialize($content[1]);
$info = null;
foreach ($content as $field => $prop){
$info .= "'$field' => array(";
foreach ($prop as $key => $value){
$info .= "'$key' => ";
if($key == 'null'){
$info .= empty($value)?'false':'true';
}elseif($key == 'default'){
$info .= empty($value)?'null':"'$value'";
}elseif($key == 'unsigned'){
$info .= empty($value)?'false':'true';
}else{
$info .= empty($value)?"''":"'$value'";
}
$info .= ", ";
}
$info .= "),\n";
}
echo "public $".$table." = array(
".$info."'indexes' => array(
'PRIMARY' => array('column' => 'id', 'unique' => 1),
),
'tableParameters' => array('charset' => 'utf8', 'collate' => 'utf8_general_ci', 'engine' => 'InnoDB')
);\n\n";
}
?>
}
Then run it in the browser and you should get some code to paste a the schema.php file. Then use the Cake console to create the tables in the MySQL database.
I am displaying an editable table in drupal with the following code
function _MYMODULE_sql_to_table($sql) {
$html = "";
// execute sql
$resource = db_query($sql);
// fetch database results in an array
$results = array();
while ($row = db_fetch_array($resource)) {
$results[] = $row;
$id = $row['id'];
$email = $row['email'];
$comment = $row['comment'];
// drupal_set_message('Email: '.$email. ' comment: '.$comment. ' id: '.$id);
}
// ensure results exist
if (!count($results)) {
$html .= "Sorry, no results could be found.";
return $html;
}
// create an array to contain all table rows
$rows = array();
// get a list of column headers
$columnNames = array_keys($results[0]);
// loop through results and create table rows
foreach ($results as $key => $data) {
// create row data
$row = array(
'edit' => l(t('Edit'),"admin/content/test/".$data['id']."/ContactUs", $options=array()),);
// loop through column names
foreach ($columnNames as $c) {
$row[] = array(
'data' => $data[$c],
'class' => strtolower(str_replace(' ', '-', $c)),
);
}
// add row to rows array
$rows[] = $row;
}
// loop through column names and create headers
$header = array();
foreach ($columnNames as $c) {
$header[] = array(
'data' => $c,
'class' => strtolower(str_replace(' ', '-', $c)),
);
}
// generate table html
$html .= theme('table', $header, $rows);
return $html;
}
// then you can call it in your code...
function _MYMODULE_some_page_callback() {
$html = "";
$sql = "select * from {contact3}";
$html .= _MYMODULE_sql_to_table($sql);
return $html;
}
However, I keep getting the mysql_num_rows() error as
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource. What is causing it?
Which version of Drupal are you using?
try db_affected_rows()
or db_num_rows()
