Foreach loop data passed to jquery

Ok, I'm going to try to explain this the best I can.

I have a product filter on my website that is built using php foreach to create the filter headers and options from a data base. The code it generates is below.

<div class="card mb-2 card-body alert-filters">
<h4>Product Filter</h4>
<div class="row">
  <div 
     class="col-md-3">
     <h5>Price</h5>
     <input type="hidden" id="hidden_minimum_price" value="0"> <input 
        type="hidden" id="hidden_maximum_price" value="50">
     <p id="price_show">£0 - £50</p>
     <div 
        id="price_range" class="ui-slider ui-corner-all ui-slider-horizontal ui-widget ui-widget- 
        content">
        <div class="ui-slider-range ui-corner-all ui-widget-header" style="left: 0%; width: 
           100%;"></div>
        <span tabindex="0" class="ui-slider-handle ui-corner-all ui-state-default" 
           style="left: 0%;"></span><span tabindex="0" class="ui-slider-handle ui-corner-all ui- 
state- default" style="left: 100%;"></span>
     </div>
  </div>
  <div class="col-md-3">
     <h5>Material</h5>
     <div 
        style="height: 180px; overflow-y: auto; overflow-x: hidden;">
        <div class="list-group-item 
           checkbox"><label><input type="checkbox" class="common_selector brand1" value="3"> 
Metal</label> 
        </div>
        <div class="list-group-item checkbox"><label><input type="checkbox" 
class="common_selector 
           brand1" value="1"> PLA</label></div>
        <div class="list-group-item checkbox"><label><input 
           type="checkbox" class="common_selector brand1" value="4"> Resin</label></div>
     </div>
  </div>
  <div 
     class="col-md-3">
     <h5>Base</h5>
     <div style="height: 180px; overflow-y: auto; overflow-x: hidden;">
        <div class="list-group-item checkbox"><label><input type="checkbox" 
class="common_selector 
           brand2" value="2"> Included</label></div>
     </div>
  </div>
  <input type="hidden" name="cPath" id="cPath" 
     value="15_13_14">
</div>

The category id is added to the class 'brand'. This is then passed to the jquery below -

$(document).ready(function(){

    filter_data();

    function filter_data()
    {
        $('.filter_data').html('<div id="loading" style="" ></div>');
        var action = 'fetch_data';
        var minimum_price = $('#hidden_minimum_price').val();
        var maximum_price = $('#hidden_maximum_price').val();
        var cPath = $("#cPath").val();
        var brand = get_filter('brand');
        $.ajax({
            url:"ext/filter/fetch_data.php",
            method:"POST",
            data:{action:action, minimum_price:minimum_price, maximum_price:maximum_price, 
    brand:brand, cPath: cPath},
            success:function(data){
                $("#product_list").html(data);
            }
        });
    }

    function get_filter(class_name)
    {
        var filter = [];
        $('.'+class_name+':checked').each(function(){
            filter.push($(this).val());
        });
        return filter;
    }

    $('.common_selector').click(function(){
        filter_data();
    });

    $('#price_range').slider({
        range:true,
        min:0,
        max:50,
        values:[0, 50],
        step:1,
        stop:function(event, ui)
        {
            $('#price_show').html('£' + ui.values[0] + ' - ' + '£' + ui.values[1]);
            $('#hidden_minimum_price').val(ui.values[0]);
            $('#hidden_maximum_price').val(ui.values[1]);
            filter_data();
        }
    });

});

This works fine if I do not add the category ID as it just uses the 'brand'.

What I am wanting to do is have a var for 'brand1', 'brand2' etc depending on how many categories there are or a way to group them together and I can split them out on the proceeding page.

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...

Where and how is this Laravel kernel constructor called? [closed]

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
