JSON.parse: unexpected end of data at
I have been reading some of the other questions here but I can't find one that fully explains how I should fix it. I am new to JSON and don't fully understand it all.
I have to search price range(min_price & max_price) from two columns(regular_price & sale_price) but unable to get values from both columns.
HTML
<div class="card mb-3">
<div class="card-body">
<p>
<label for="amount">amount:</label>
<input type="text" name="amount" id="amount" readonly class="border-0 fw-bold text-warning">
</p>
<div id="slider-range"></div>
</div>
</div>
SCRIPT
<script src="{{ asset('themes/js/jquery-ui.js') }}"></script>
<script>
$( function() {
$( "#slider-range" ).slider({
range: true,
min: {{ $min_price }},
max: {{ $max_price }},
values: [ 0, {{ $max_price }} ],
slide: function( event, ui ) {
var amount = $( "#amount" ).val( " $ " + ui.values[ 0 ] + " - $ " + ui.values[ 1 ] );
$.ajax({
type: 'POST',
dataType: 'json',
url: '{{ route('priceFilter') }}',
data: {amount: amount.val()},
success: function (data) {
if (!data.error) {
var data = JSON.parse(data);
$.each(data, function (index, element) {
console.log(element);
});
}
}
});
}
});
$( "#amount" ).val( " $ " + $( "#slider-range" ).slider( "values", 0 ) + " - $ " + $( "#slider-range" ).slider( "values", 1 ) );
});
</script>
Controller
public function priceFilter(Category $category, Request $request)
{
$categories = Category::all();
$colors = Color::all();
$brands = Brand::all();
$min_price = Product::min('price');
$max_price = Product::max('price');
$filter_min_price = $request->min_price;
$filter_max_price = $request->max_price;
$range = [$filter_min_price, $filter_max_price];
$products = Product::query()->whereBetween('price', $range)->get();
if($filter_min_price && $filter_max_price){
if($filter_min_price > 0 && $filter_max_price > 0)
{
$products = Product::all()->whereBetween('price', [$filter_min_price, $filter_max_price]);
}
} else {
$products = Product::all();
}
return response()->json($category);
//return view('Home.contents.category',compact('products','categories','min_price','max_price','filter_min_price','filter_max_price', 'category', 'colors', 'brands'));
}
I see this error.
Uncaught SyntaxError: JSON.parse: unexpected end of data at line 1 column 1 of the JSON data

You get $categories
Then you get products (twIce)
Then you just return a json encoded version of the category model
You have tested this function haven't you? You have looked in the browser network tool haven't you? YOU HAVE LOOKED IN THE LARAVEL LOGS HAVEN'T YOU ??????

@qhom I have a desk that I sit at every day, thanks. Why? Are you giving up programming and going into office furniture? That would be a wise career move.

@Snapey I did not understand what you meant.

You're returning $category variable which even doesn't exist in your code, I think want to return $products
public function priceFilter(Category $category, Request $request)
{
$categories = Category::all();
$colors = Color::all();
$brands = Brand::all();
$min_price = Product::min('price');
$max_price = Product::max('price');
$filter_min_price = $request->min_price;
$filter_max_price = $request->max_price;
$range = [$filter_min_price, $filter_max_price];
$products = Product::query()->whereBetween('price', $range)->get();
if($filter_min_price && $filter_max_price){
if($filter_min_price > 0 && $filter_max_price > 0)
{
$products = Product::all()->whereBetween('price', [$filter_min_price, $filter_max_price]);
}
} else {
$products = Product::all();
}
return response()->json($products);
}
