I have this function created to show a piechart but I need each element to show a different color. For this I have created an array with all the colors and I need in each iteration of the reduce() method to have an index to access the colors[i]. I have tried this way and it does not work. Any suggestion?
$i = 0;
$pieChartModel = $options->groupBy('survey_options_id')
->reduce(function (PieChartModel $pieChartModel, $data) use ($i) {
$type = $data->first()->survey_options_id;
$value = $data->sum('value');
// $color = "#" . substr(md5(rand()), 0, 6);
$NameOption = Survey_options::where('id', $type)->pluck('name');
return $pieChartModel->addSlice($NameOption, $value, $this->colors[$i]->hexa);
$i++;
}, (new PieChartModel())->setAnimated($this->firstRun)->setDataLabelsEnabled(true));
A problem I'm seeing in your code is how you're incrementing $i AFTER a return statement.
After taking a look at the source code for the reduce() function
/**
* Reduce the collection to a single value.
*
* #param callable $callback
* #param mixed $initial
* #return mixed
*/
public function reduce(callable $callback, $initial = null)
{
$result = $initial;
foreach ($this as $key => $value) {
$result = $callback($result, $value, $key);
}
return $result;
}
You should be able to use the key (or index) in the callback.
->reduce(function ($carry, $item, $key) { ... }, $initial)
->reduce(function (PieChartModel $pieChartModel, $data, $i) {
...
}, (new PieChartModel())->setAnimated($this->firstRun)->setDataLabelsEnabled(true))
I need pagination for my collection in which I have to apply lots of filters. But I'm unable to achieve this. I'm new to laravel so please show me the right way.
My controller:
public function index(Request $request)
{
$view = $request['view'] ? $request['view'] :'grid';
$purpose = $request['purpose'] ? $request['purpose'] : 'rent';
$sort = $request['sort'] ? $request['sort'] : 'asc';
$properties = $properties->where('purpose' , $purpose);
if($sort == 'asc');
$properties = $properties->sortBy('price');
else
$properties = $properties->sortByDesc('price');
$properties = $properties->paginate(5);
return view('frontend.properties.index', [ 'view'=>$view , 'properties' => $properties , 'request'=> $request->all() ]);
}
I have had this issue and in order to solve that, I have created a trait called PaginateCollection:
/*
* Paginate the Laravel Collection before and/or after filtering.
*
*/
trait PaginateCollection
{
/**
* Paginate the collection.
*
* #param \Illuminate\Support\Collection|\Illuminate\Database\Eloquent\Collection $collection
* #param integer $perPage
* #param integer $currentPage
* #return \Illuminate\Pagination\LengthAwarePaginator
*/
public function paginate($collection, $perPage = 10, $currentPage = 1)
{
$offSet = ($currentPage * $perPage) - $perPage;
$otherParams = [
'path' => request()->url(),
'query' => request()->query()
];
return new LengthAwarePaginator(
$collection->forPage(Paginator::resolveCurrentPage() , $perPage),
$collection->count(),
$perPage,
Paginator::resolveCurrentPage(),
$otherParams
);
}
}
Perhaps, this should help you out.
I use the standart method for pagination:
$ann = Ann::get()->orderBy('id', 'desc')->paginate($limit);
After I do merge $ann with another collection:
$ann = $ann->merge($ann_subscribed);
$ann = $ann->all();
In result I get $ann = $ann->all(); without pagination
1- add this to boot function in \app\Providers\AppServiceProvider
/**
* Paginate a standard Laravel Collection.
*
* #param int $perPage
* #param int $total
* #param int $page
* #param string $pageName
* #return array
*/
Collection::macro('paginate', function($perPage, $total = null, $page = null, $pageName = 'page') {
$page = $page ?: LengthAwarePaginator::resolveCurrentPage($pageName);
return new LengthAwarePaginator(
$this->forPage($page, $perPage),
$total ?: $this->count(),
$perPage,
$page,
[
'path' => LengthAwarePaginator::resolveCurrentPath(),
'pageName' => $pageName,
]
);
});
2-From hereafter for all collection you can paginate like this
$ann = Ann::orderByRaw('id','DESC')->get();
$ann_merged = $ann->merge($ann_subscribed);
$ann_merged ->paginate(5);
I have made an own viewhelper for getting external images (thanks to robert pflamm see Typo3 fluid image from external resource). if i use only ImageViewHelper everything is working finde.
But if i use \TYPO3\CMS\Fluid\ViewHelpers\Uri\ImageViewHelper the image is only rendered once. Same problem as here TYPO3 ver. 7.6.2 - Condition ViewHelpers evaluated only once. but i do not know how to solve it
Can anyone please help?

The viewhelpers are not really a public API which are meant to be extensible by custom ViewHelpers!
The problem you are facing is that after the 1st call, the ViewHelpers are compiled and the method renderStatic is used which you don't override.
The best solution would be that you copy the code of the parent class and only extend from AbstractViewHelper or AbstractTagBasedViewHelper
is it possible to resize images in fluid from external resource. I have an extension with datas from SOAP. So image URL looks like http://www.example.com/url/of/image/imagename.jpg.
<f:image src="{data.url.image}" with="300" />
is not working.
Maybe an own ViewHelper which fetch the external image and save it to an temporary folder could help. After this you can modify the image.
Something like this (not tested):
<?php
namespace MyNamespaece\MyExt\ViewHelpers;
use TYPO3\CMS\Core\Utility\GeneralUtility;
use TYPO3\CMS\Fluid\ViewHelpers\ImageViewHelper;
use TYPO3\CMS\Core\Resource\FileInterface;

Please Note: This ViewHelper has no check if the image is allready fetched! So an check should be integrated. Otherwise this viewhelper fetch the image at each page refresh!
As mentioned in the comments I want to clarify that this ViewHelper should not be used in any production environment. It should only demonstrate how the way to such an viewhelper could be. Compiled templates are not supported. Also no needed check if the file already exists is implemented. Your hosting environment could be flooded with downloads and can break you file quota!
The short answer is: This is not possible.
The long answer is: Of course it is possible if you fetch the image first. There are various ways to do it:
At runtime as rpflamm suggested by using a ViewHelper
Do it in your controller/service when you fetch the SOAP call. IMO this would be the best way. Persist then the image and use the local path
If the images you fetch are not that big, of course a resizing via CSS is also an option
