Geo hash – getting nearby location in firebase realtime database using php or laravel php

We are developed the location based projects . i am very struggled with getting nearbase location data in firebase database using laravel php . below is my code . please help me to that how to get the nearby location datas using geo hash in laravel php based on the radis .

$fire_drivers = $this->database->getReference(‘drivers’)->orderByChild(‘g’)->startAt($lower_hash)->endAt($higher_hash)->getValue();

    $firebase_drivers = [];

    $i=-1;

    foreach ($fire_drivers as $key => $fire_driver) {
        $i +=1; 
        
        $driver_updated_at = Carbon::createFromTimestamp($fire_driver['updated_at'] / 1000)->timestamp;


    if(array_key_exists('vehicle_type',$fire_driver) && $fire_driver['vehicle_type']==$vehicle_type && $fire_driver['is_active']==1 && $fire_driver['is_available']==1 && $conditional_timestamp < $driver_updated_at){


            $distance = distance_between_two_coordinates($pick_lat,$pick_lng,$fire_driver['l'][0],$fire_driver['l'][1],'K');

            if($distance <= $driver_search_radius){

                $firebase_drivers[$fire_driver['id']]['distance']= $distance;

            }

        }elseif(array_key_exists('vehicle_types',$fire_driver)  && in_array($vehicle_type, $fire_driver['vehicle_types']) && $fire_driver['is_active']==1 && $fire_driver['is_available']==1 && $conditional_timestamp < $driver_updated_at)
            {


            $distance = distance_between_two_coordinates($pick_lat,$pick_lng,$fire_driver['l'][0],$fire_driver['l'][1],'K');

            if($distance <= $driver_search_radius){

                $firebase_drivers[$fire_driver['id']]['distance']= $distance;

            }

        }

    }

    asort($firebase_drivers);

Cookie was blocked because neither did the request URL’s domain exactly | Next js and Node js

I’ve developed a Node.js backend paired with a Next.js frontend. The Node.js backend is hosted on sub2.sub1.example.com, and the frontend is situated at sub1.example.com. To authenticate users, I employ a Next.js middleware that validates the token stored as a cookie on the client’s computer.

Upon a user’s login attempt, the cookie is set. However, during the redirection to the dashboard page, the cookie isn’t send along with the get request to the next js server. Due to this the middleware redirects back enter image description hereto login page.

How to draw complex SVGs within a Flutter Application?

I am developing an application with Flutter that involves render, and then interacting with, an svg-encoded piece of sheet music. Specifically, I need to be able to draw and re-draw quickly, and get the id attribute of whatever element is under any mouse events. Doing this in a Javascript environment (not in Flutter) is quite easy and just requires adding in the svg to a , and attaching a mouse listener.

The specific problem that I am running into in Flutter is that none of the svg libraries support the kinds of features that this sheet music encoding scheme uses (nested tag, tag, , , overflow attributes, etc). So my question is, what can I do to get this kind of svg rendering? And does that still allow for determining the element that is under a mouse event?

I imagine that converting the svg to an image (png, jpeg, etc) is too slow, and that would require re-rendering the image to a different resolution when the user scrolls. What options exist? Is there a way to define a different drawing solution for each platform I want to use? I hope to port my application to Desktop (primary platform), Web (in a limited capacity), and perhaps Mobile.

I have tried the following libraries in flutter’s pub dev:
flutter_svg
jovial_svg

Neither of them were able to render any kind of image from my svg file. Though I got both to work with a simple svg file (an example dart icon)

Thanks for any suggestions and help!

How to change color of leaflet marker svg

how can i change only the color of the marker? previously i used just two svgs, one that is active and one that is not, now i wanted to add more icons and making two copies of each icon just to show its active state is not very good approach ig, what can i do?
i tried with divIcon and replacing its html but that didnt work either

icon = L.divIcon({
    className: "custom-icon",
    html: iconSvg,
    iconSize: [24, 24],
    iconAnchor: [12, 12],
  });

        active.options.icon.options.html.replace(
          'fill="#FFD400"',
          'fill="#FF1900"'
        );

How can I get the parent coordinates when clicking an iframe inside it

i want to get the coordinates of the parent containing a div when clicking inside the div. I already add an event listener in the iframe and I send the coordinates via postMessage but those are the coordinates of the iframe itself, I want the coordinates of the parent window, those are different. How can i achieve this?

I’ve already tried something like this:

useEffect(() => {
    const iframe = document.getElementById('titanpad') as HTMLIFrameElement;
    const iframeDocument = iframe?.contentDocument || iframe?.contentWindow?.document;

    const handleClick = (event: MouseEvent) => {
      const x = event.clientX;
      const y = event.clientY;
      setClickCoordinates({ x, y });
    };

    if (iframeDocument) {
      iframeDocument.addEventListener('click', handleClick);
    }

    return () => {
      if (iframeDocument) {
        iframeDocument.removeEventListener('click', handleClick);
      }
    };
  }, []);

This didn’t work.

send data from javascript to django without sending request, post, get

I have a project is about web game, if the player end the game

#e.g.
bool state == false

then it will send the score back to the django backend, but i don’t want the player have to press the submit button, is there any ways to do that?

i have no any complete idea, i just found some solution is about ajax, fetch api…, but i don’t really know if those work or not.

my post can’t pass the quality standard, is that means my post’s word too less?

Alternate solution for the deprecated execCommand when copying a rich-text from the displayed HTML

I have this javascript to copy some rich text (for example bolds, tables, etc.) when a button is clicked:

<script>
    window.addEventListener( 'load', () => {
        const btnCopy = document.getElementById( 'my-nice-btn-copy' );
        const richTextToCopy = document.getElementById( 'some-complex-html-structure' );

        btnCopy.addEventListener('click', () => {
            const range = document.createRange();
            range.selectNode( richTextToCopy );
            window.getSelection().removeAllRanges();
            window.getSelection().addRange( range );

            document.execCommand( 'copy' );
            window.getSelection().removeAllRanges();
        });
    } );
</script>

PhpStorm tells me that execCommand() is deprecated.

Here it says I should use the Clipboard API but here it says I need to create a new ClipboardItem element and there I start getting lost.

How should I modify my javascript function to use the native Clipboard API?

TypeError: setOpenModal is not a function (ReactJs)

I am getting an error when trying to display a dialog modal in ReactJS. First, I pass the state of the dialog into a page, which is Work.jsx, which renders a component named ProjectCard. Inside the component ProjectCard, I pass in the states of the opening and closing of it. Now, inside the ProjectCard component, I have an event listener onclick. When somebody clicks on that component, the dialog will show. As soon as it shows, I change its state to true and pass in the data it’s supposed to render, which is the ProjectDetails component given below. I get an error in the ProjectCard component when I click it, saying that setopenmodal is not a function. Can someone please explain what it means? Here is the code… The error is inside the ProjectCard component on the card click event listener.

Using prototypes to check whether an object is an instance of a class

I tried to solve the 2618s problem in LeetCode “https://leetcode.com/problems/check-if-object-instance-of-class/description/” and wanted to know if there is a way to resolve it using only properties like prototype, proto and constructor, without a while loop and instanceof? Any help please.

Theres a bunch of examples I tried but nothing works

  return obj.constructor.prototype === classFunction.prototype


 if (classFunction === Number || classFunction === String || classFunction === Date) {
        return obj.__proto__ === classFunction.prototype
    } else return obj.__proto__.constructor.__proto__.prototype === classFunction.prototype

How do I retrieve the values of a radio group from an HTML dialog?

index.html:

  <body>
    <dialog class="dialog">
      <form class="report__form" method="dialog">
        <div>
          <input type="radio" name="report" vale="vulgar" />
          <label for="vulgar">Vulgar/Offensive Language</label>
        </div>
        <div>
          <input type="radio" name="report" vale="duplicate" />
          <label for="Duplicate">Duplicate</label>
        </div>
        <div>
          <input type="radio" name="report" vale="broken" />
          <label for="broken">Broken</label>
        </div>
        <button class="dialog__submit">Submit</button>
      </form>
    </dialog>
    <button class="open">open dialog</button>
    <script src="script.js"></script>
  </body>

script.js:

const dialog = document.querySelector(".dialog");
const reportForm = document.querySelector(".report__form");
const submitButton = document.querySelector(".dialog__submit");
const openButton = document.querySelector(".open");

openButton.addEventListener("click", () => {
  dialog.showModal();
});

I’m having a hard time figuring out how to retrieve the radio input values within an HTML dialog. I read the MDN docs on radio inputs but am still struggling to get it to work within the context of a dialog. I figure I need to set a default value, loop through the inputs, and update that value if I click one of them, but I can’t get it to work.
