Not quite clear where you are missing data? Which part is an empty string exactly?

GEt only an empty string from ajax request
Hello, im trying to build an function, and i think it should work but my get request is always sending an empty string and not the rendered view. Does anybody have an ides where the mistake is.
My Function in the controller.
public function order($request)
{
$value = $request->input('value');
$section = $request->input('section');
switch ($section) {
case 'mediadata':
$categories = Category::where(Category::ATTRIBUTE_PUBLICATION_TYPE, Category::TYPE_MEDIA_DATA)
->where(Category::ATTRIBUTE_IS_ONLINE, 1)->get();
$publications = [];
foreach ($categories as $cat) {
foreach ($cat->publications as $pub) {
$publications[] = $pub;
}
}
$publications = collect($publications)->sortBy('name');
$letters = [];
$publicationLetter = [];
foreach ($publications as $publication) {
$letters[] = strtoupper($publication->name[0]);
$letters = array_unique($letters);
foreach ($letters as $letter) {
if ($letter === strtoupper($publication->name[0])) {
$publicationLetter[$letter][] = $publication;
}
}
}
$sortedArray = collect($publicationLetter)->sortKeys();
$view = view('frontend.mediaData.sortData', compact('sortedArray'));
break;
}
return $view->render();
}
My AJAX Function
function getFilteredData(type, section) {
let value
switch (type) {
case 'search':
value = $('#searchField').val()
break
case 'order':
value = $('#selectField').val()
break
}
$.ajax({
url: '{{route('filter')}}',
method: 'get',
data: {
type,
section,
value,
},
success: (res) => {
console.log(res)
$('.filter-container').html(res)
},
})
}

@Sinnbeck Hello, right here in the response
success: (res) => {
console.log(res) // Throws out <empty string>
$('.filter-container').html(res)
},

@libertey Try opening dev tools (f12) in chrome and select network. Now do the request, and click on the request in the list. Then select the preview tab. Does that have data?
Btw. No need to call render() on the view
return $view;
Level 1
And if i render it inside the case like that
$view = view('frontend.mediaData.sortData', compact('sortedArray'))->render();
dd($view);
My HTML is rendered absolutely correct, it just does not return the HTML.
Level 102
Also be sure to have a default in the switch. If $section isnt "mediadata", you never set a view? (I assume there is supposed to be multiple cases, but you havent written them yet)
Level 1
@Sinnbeck yes the default is set, the other cases are the next step, and on f12 in network tab there is nothing in the preview.
Level 102
@libertey Then you need to use dd() at different points in the code to see where it goes wrong. Is it correct to assume that you are not showing the complete code as there is no default case?
Level 1
@Sinnbeck This is my full switch function till now
$value = $request->input('value');
$section = $request->input('section');
switch ($section) {
case 'mediadata':
$categories = Category::where(Category::ATTRIBUTE_PUBLICATION_TYPE, Category::TYPE_MEDIA_DATA)
->where(Category::ATTRIBUTE_IS_ONLINE, 1)->get();
$publications = [];
foreach ($categories as $cat) {
foreach ($cat->publications as $pub) {
$publications[] = $pub;
}
}
$publications = collect($publications)->sortBy('name');
$letters = [];
$publicationLetter = [];
foreach ($publications as $publication) {
$letters[] = strtoupper($publication->name[0]);
$letters = array_unique($letters);
foreach ($letters as $letter) {
if ($letter === strtoupper($publication->name[0])) {
$publicationLetter[$letter][] = $publication;
}
}
}
$sortedArray = collect($publicationLetter)->sortKeys();
$view = view('frontend.mediaData.sortData', compact('sortedArray'))->render();
dd($view); // here it returns the correct value of the view I want to render
return $view; // it returns <empty string>
break;
default:
return redirect()->back();
}
Level 102
@libertey You cannot return back in an ajax request.
Level 1
@Sinnbeck yeah i will adjust the default one later, will build an error blade which should be rendered if section is not set... right now it will only work for section 'mediadata' there are several other things the function has to do, but first of all i try to get that thing working.
Because mediadata is set as section and it runs straight till the dd() but the return state is not rendering anything.
Level 102
@libertey If you just open the url directly in a browser tab, does it work there? Rightclick the request in the list, and select "Open in new tab"
Level 1
@Sinnbeck No also not working
Level 102
@libertey Can you return an arbitrary string?
return 'it works';
Level 1
@Sinnbeck OMG I'm so sorry that i wasted your time, I forgot i had an main function, where it filters (not the best solution, must work over that) the filter type, called filter() and i forgot to put the return statement before that function...
public function filter(Request $request)
{
$type = $request->input('type');
switch ($type) {
case 'search':
return $this->search($request);
break;
case 'order':
return $this->order($request); // i forgot to return it in here -.-
default:
return $this->error();
}
}
