I'm having trouble creating a function on collection map with return values.
public function getCollectionFakeId($collection, $fieldNames){
$optimus = $this->optimus;
$result = $collection->map(function($item, $key) use ($optimus, $fieldNames) {
return [
$fieldNames[0] =>$optimus->encode($item->id),
$fieldNames[1] => $item->lastname
];
}) ;
dd($result);
return json_decode(json_encode($result), FALSE);
}
As you can see the return fieldNames[0] is being hardcoded. I don't know how many fieldNames it will received. I need to return those fieldnames with obfuscated Id. So basically The only changed is the Id. Here is the screenshot.
As you can see the fieldNames are just 2 but what if it becomes 5 or 6. I don't really know how many fieldNames they are going to pass in the parameter. How can I return it. Thanks.
In case someone will encounter this problem. Here is my solution...
public function getCollectionFakeId($collection, $fieldNames){
$optimus = $this->optimus;
$result = $collection->map(function($item, $key) use ($optimus, $fieldNames) {
$mapFieldNames = array_map(function($v) use ($optimus, $item) {
if( $v == 'id'){
return $optimus->encode($item->id);
}
else{
return $v;
}
}, $fieldNames);
return $mapFieldNames;
}) ;
dd($result);
return json_decode(json_encode($result), FALSE);
}
The result is the same. AWESOME!

so, I have 2 tables, stage and event. Stage hasMany event, and Event belongsTo Stage. And I want to show all stage and its event as json. Here is my code in controller:
public function getschedule(){
$schedule = Stage::all();
//$event = Event_schedule2020::all();
if (!$schedule) {
return response()->json(['msg'=>'Error not found','code'=>'404']);
}
foreach($schedule->events as $array){
$datax[] = [
'id'=>$array->id,
'time'=>$array->time,
'category'=>$array->category,
'type'=>$array->title,
'designer'=>$array->designer,
];
}
foreach ($schedule as $item) {
$jadwal[] = [
'id'=>$item->id,
'date'=>$item->date,
'place'=>$item->stage,
'data'=>$datax,
];
}
return response()->json($jadwal);
}
but I always get this error
the error
so, is there anything I can do about this?
You can utilize inbuilt functions to do what you want to. Laravel automatically transforms model into JSON, no need to built arrays with it.
public function getschedule() {
// tell laravel you want to eager load events
$stages = Stage::with('events')->get();
// laravel knows you loaded events and therefor you can just return it and it does the rest automatically
return response()->json($stages);
}
in your Stage model you have to create relationship like this
public function events()
{
return $this->hasMany('App\Event');
}
then in your Controller
public function getschedule(){
$schedules = Stage::with('events')->get()->toArray();
return response()->json($schedules );
}
your mistake is call events on a collection for solve this you can change foreach like followings :
public function getschedule(){
$schedules = Stage::all(); // I add a 's' to $schedule because is better set plural name;
if (!$schedule) {
return response()->json(['msg'=>'Error not found','code'=>'404']);
}
foreach($schedules as $schedule){
$datax = [];
foreach($schedule->events as $event){
$datax[] = [
'id'=>$event->id,
'time'=>$event->time,
'category'=>$event->category,
'type'=>$event->title,
'designer'=>$event->designer,
];
}
$jadwal[] = [
'id'=>$item->id,
'date'=>$item->date,
'place'=>$item->stage,
'data'=>$datax,
];
}
return response()->json($jadwal);
}
but above solution is not recommended because send many request to server in any foreach loop, following solution is better:
public function getschedule(){
$schedules = Stage::with('events')->get(); // only this difference with above soloution and the rest is the same
if (!$schedule) {
return response()->json(['msg'=>'Error not found','code'=>'404']);
}
foreach($schedules as $schedule){
$datax = [];
foreach($schedule->events as $event){
$datax[] = [
'id'=>$event->id,
'time'=>$event->time,
'category'=>$event->category,
'type'=>$event->title,
'designer'=>$event->designer,
];
}
$jadwal[] = [
'id'=>$item->id,
'date'=>$item->date,
'place'=>$item->stage,
'data'=>$datax,
];
}
return response()->json($jadwal);
}
I'm just new in laravel. I want to know. how to return multiple data/value.
public function readItems() {
$data1 = Data1::all ();
$data = Data::all ();
return $data;
}
I'm quite confuse how to do it. I don't to return it as a view, i just want to return only the data. i hope someone could help. thanks a lot..
You could return an array like :
return [data1, $data];
In the other side read it like :
$response = readItems();
$data1 = $response[0];
$data = $response[1];
You can send data to view as like below :
return view('index', ['Data_One'=>$data, 'Data_Two'=>$data1]);
I want to ask. I use foreach for showing my data from database. But nothing happen on view. Here is my code :
public function page($page_url = null){
if($page_url == "villas"){
$villa = Pages::where(['url_page' => $page_url])->first();
$postvilla = Posts::where(['id_page' => $villa->id_page]);
return view('front.villa', compact(array('villa', 'postvilla')));
}else if($page_url == "admin"){
return redirect('/admin/home');
}
}
You can pass variables in compact like
return view('front.villa', compact('villa', 'postvilla'));
I have a given table :
tools toolparts parts part_details
----- --------- ----- ------------
id* id* id* id*
name tool_id name part_id
part_id total (int)
----- --------- ----- ------------
the relation between Tools and Parts is ManyToMany. and the relation between parts and part_details is one to many.
with Laravel model, how can I get tool with part that has the biggest part_details.total ??
//tool model
public function parts()
{
return $this->belongsToMany('App\Part', 'tool_part');
}
//part model
public function tools()
{
return $this->belongsToMany('App\Tool', 'tool_part')
}
public function details(){
return $this->hasMany('App\Part_detail');
}
//partDetail model
public function part(){
return $this->belongsTo('App\Part');
}
Controller
public function index()
{
$tools = Tool::with('parts', 'parts.details')->has('parts')->get();
return $tools;
}
what I expected is something like :
Controller
public function index()
{
$tool = Tool::with('SinglePartThatHasHigestTotalInPartDetail');
}
Any Idea ??
You can use Laravel aggregates for querying to get the desired result,
In your code use max() function,
public function index()
{
$tool = Tool::with(['parts.part_details' => function ($query) {
$max = $query->max('total');
$query->where('total',$max);
})->first();
}
I haven't tested this but you can do like this.
Comment if you will get any errors.
I Manage my problem with "hacky" ways. if someone have a better and more elegant solution, please tell me.
//tool model
public function partWithHighestTotalDelivery($trans_date = null){
if (is_null($trans_date)) {
$trans_date = date('Y-m-d');
}
$parts = $this->parts;
$highest_total_delivery = 0;
foreach ($parts as $key => $part) {
$part->detail;
$total_delivery = $part->first_value;
if (isset( $part->detail->total_delivery )) {
$total_delivery += $part->detail->total_delivery;
}
if ($highest_total_delivery < $total_delivery ) {
$highest_total_delivery = $total_delivery;
$part->total_delivery = $highest_total_delivery;
$result = $part;
}
}
if (!isset($result)) {
$result = null;
}
$this->part = $result;
}
In controller i have :
public function index(Request $request){
$tools = Tool::has('parts')
->get();
$tools->each(function($tool){
$tool->partWithHighestTotalDelivery();
});
return $tools;
}
with this, I need to run tool->partWithHighestTotalDelivery() tools.count times. which is take noticeable process if the tools is many.
and also, the code I post and the question I ask has a slightly difference.that's for a simplicity sake's
Use the the hasManyThrough Relationship to get the all part details related to tool and then you can check the one by one record and get the highest total of the tool part.
// Tool Model
public function partsdetails()
{
return $this->hasManyThrough('App\PartDetail', 'App\Part','tool_id','part_id');
}
In Your controller
$data = Tool::all();
$array = [];
if(isset($data) && !empty($data)) {
foreach ($data as $key => $value) {
$array[$value->id] = Tool::find($value->id)->partsdetails()->max('total');
}
}
if(is_array($array) && !empty($array)) {
$maxs = array_keys($array, max($array));
print_r($maxs);// This array return the max total of the tool related parts
}
else{
echo "No Data Available";
}
You can start with the part detail and get the tool(s) from there:
$maxPartDetail = Part_detail::orderByDesc('total')->first();
$tools = $maxPartDetail->part->tools;
How do I add custom sort option in Magento. I want to add Best Sellers, Top rated and exclusive in addition to sort by Price. Please help
For Best Sellers
haneged in code/local/Mage/Catalog/Block/Product/List/Toolbar.php method setCollection to
public function setCollection($collection) {
parent::setCollection($collection);
if ($this->getCurrentOrder()) {
if($this->getCurrentOrder() == 'saleability') {
$this->getCollection()->getSelect()
->joinLeft('sales_flat_order_item AS sfoi', 'e.entity_id = sfoi.product_id', 'SUM(sfoi.qty_ordered) AS ordered_qty')
->group('e.entity_id')->order('ordered_qty' . $this->getCurrentDirectionReverse());
} else {
$this->getCollection()
->setOrder($this->getCurrentOrder(), $this->getCurrentDirection());
}
}
return $this;
}
After setCollection I added this method:
public function getCurrentDirectionReverse() {
if ($this->getCurrentDirection() == 'asc') {
return 'desc';
} elseif ($this->getCurrentDirection() == 'desc') {
return 'asc';
} else {
return $this->getCurrentDirection();
}
}
And finally I changed mehod setDefaultOrder to
public function setDefaultOrder($field) {
if (isset($this->_availableOrder[$field])) {
$this->_availableOrder = array(
'name' => $this->__('Name'),
'price' => $this->__('Price'),
'position' => $this->__('Position'),
'saleability' => $this->__('Saleability'),
);
$this->_orderField = $field;
}
return $this;
}
for Top rated

try above code.
for date added

i am not associate with any of the above link for any work or concern it is just for knowledge purpose and to solve your issue.
hope this will sure help you.
Thanks for your answer, Anuj, that was the best working module I could find so far.
Just add an extra bit to your code in order to solve no pagination caused by 'group by'
Copy '/lib/varien/data/collection/Db.php'
To 'local/varien/data/collection/Db.php'.
Change the getSize function to
public function getSize()
{
if (is_null($this->_totalRecords)) {
$sql = $this->getSelectCountSql();
//$this->_totalRecords = $this->getConnection()->fetchOne($sql, $this->_bindParams); //============================>change behave of fetchOne to fetchAll
//got array of all COUNT(DISTINCT e.entity_id), then sum
$result = $this->getConnection()->fetchAll($sql, $this->_bindParams);
foreach ($result as $row) {//echo'<pre>'; print_r($row);
$this->_totalRecords += reset($row);
}
}
return intval($this->_totalRecords);
}
Hope it could help anyone.
update
The filter section need to be updated as well, otherwise just showing 1 item on all filter.
and the price filter will not be accurate.
What you need to do it to modify core/mage/catalog/model/layer/filter/attribute.php and price.php
attribute.php getCount() on bottom
$countArr = array();
//print_r($connection->fetchall($select));
foreach ($connection->fetchall($select) as $single)
{
if (isset($countArr[$single['value']]))
{
$countArr[$single['value']] += $single['count'];
}
else
{
$countArr[$single['value']] = $single['count'];
}
}
//print_r($countArr);//exit;
return $countArr;
//return $connection->fetchPairs($select);
Price.php getMaxPrice
$maxPrice = 0;
foreach ($connection->fetchall($select) as $value)
{
if (reset($value) > $maxPrice)
{
$maxPrice = reset($value);
}
}
return $maxPrice;
If you are having the same problem and looking for the question, you will know what I meant.
Good luck, spent 8 hours on that best sell function.
Update again,
just found another method to implement
using cron to collect best sale data daily saved in a table that includes product_id and calculated base sale figure.
then simply left join, without applying 'group by'
that means core functions do not need to changed and speed up the whole sorting process.
Finally finished! hehe.
To sort out pagination issue for custom sorting collection rewrite the resource model of it's collection from
app\code\core\Mage\Catalog\Model\Resource\Product\Collection.php
And modify below method from core
protected function _getSelectCountSql($select = null, $resetLeftJoins = true)
{
$this->_renderFilters();
$countSelect = (is_null($select)) ?
$this->_getClearSelect() :
$this->_buildClearSelect($select);
/*Added to reset count filters for Group*/
if(count($countSelect->getPart(Zend_Db_Select::GROUP)) > 0) {
$countSelect->reset(Zend_Db_Select::GROUP);
}
/*Added to reset count filters for Group*/
$countSelect->columns('COUNT(DISTINCT e.entity_id)');
if ($resetLeftJoins) {
$countSelect->resetJoinLeft();
}
return $countSelect;
}
Above will solve count issue for custom sorting collection.
