I’m Trying to make Conditional Delivery Notice based on Time and Date in Woocommerce
and want to display week days specific language.

   //Next Day Delivery Calculator
    add_action( 'woocommerce_before_checkout_form', 'next_day_delivery' );
    add_action( 'woocommerce_before_cart', 'next_day_delivery' );
    
    function next_day_delivery() {
        if( WC()->cart->is_empty() )
            return; // Exit
    
        // Set the time zone
        date_default_timezone_set('Asia/Tbilisi');
        
    
        // From Monday to Friday
        $is_week_days  = in_array( date('w'), array( 1, 2, 3, 4, 5 ) ) ? true : false;
        $end_time      = mktime('14', '00', '00', date('m'), date('d'), date('Y'));
        $now_time      = time();
        $after_tomorow = date('l', strtotime('+2 days'));
    
        $dateDiff      = intval(($end_time - $now_time)/60);
        $diff_hours    = intval($dateDiff/60);
        $diff_minutes  = $dateDiff%60;
        $hours_label   = _n( 'საათი', 'საათი', $diff_hours, 'wooocommerce' );
        $minutes_label = _n( 'წუთი', 'წუთი', $diff_minutes, 'wooocommerce' );
    
        
    
        if ( $end_time > $now_time && $is_week_days ) {
            
            // print text 
            $message = sprintf( __( '%s დარჩა შეკვეთის გასაფორმებლად თუ გსურთ ჩაგბარდეთ ხვალ!', 'woocommerce' ),
            $diff_hours.' '.$hours_label.' და '.$diff_minutes.' '.$minutes_label);
        }
        elseif ( $end_time <= $now_time && $is_week_days ) {
            
            $message = sprintf( __( 'თქვენ მიიღებთ შეკვეთას %s.', 'woocommerce' ), $after_tomorow );
        } else {
            $message = __( 'თქვენი შეკვეთა ფორმირდება ორშაბათს და ჩაგბარდებათ სამშაბათს.', 'woocommerce' );
        }
        wc_print_notice( $message, 'success' );
    }

also want to make conditional checkbox based shipping class. (if shipping class is express its same day delivery must hide notice about shipping date)

//Hide Delivery Message Express Shipping Checked

    add_action( 'woocommerce_after_checkout_form', 'show_notice_billing' );
    function show_notice_billing(){
        ?>
            <script>
            jQuery(function($){
               $(document).ready(function() {
        $(document).on("click", "#shipping_method_0_flat_rate-12", function(e) {
           var checked = $(this).find("input:checkbox").is(":checked");
           if (checked) {
               $('.woocommerce-message').hide(300);
           } else {
               $('.woocommerce-message').show(300);
           }
        });
    });
            });
        </script>

I am building a student application management system using PHP, JavaScript. Each student has a unique ID. There will be a system for students to submit applications. If you select the ID of any student, the First name, last name of the student will come down automatically. I was able to get the first name of the student using JavaScript. But I could not bring the last name of students. When I select last name it is vanished automatically. My Code is:

                    <div class="form-group">
                        <label class="col-sm-3 control-label right"><strong>Student Id</strong></label>

                            <?php

                                $username = '';
                                $query = "SELECT username FROM users where ref ='".$uid."'";
                                $result = mysqli_query($conms, $query);
                                while($row = mysqli_fetch_array($result))
                                {
                                    $username .= '<option value="'.$row["username"].'">'.$row["username"].'</option>';
                                }

if ($(".nvabarTogglerButtonProduct").hasClass("collapsed"))

how can we replace this with vanila javascript I have try this that way

if (document.querySelector('.nvabarTogglerButtonProduct").classList.contains("collapsed"))

but this code is not working please suggest me some good replacement for this

This is client-side HTML. I’m just using HTML for automation.

My initial goal was to open a new window https://live.ipms247.com/login/ and then paste the values in the three login fields. All three fields have ID tags. And I can write to them from the console. For example.

document.getElementById("username").value="sample"; 
document.getElementById("hotelcode").value="12345"; 
document.getElementById("password").value="Password";

I wrote a code to copy text from parent window to child window at the click of a button.
My code is on a local file.

<html>
<head>
<script type="text/javascript">
function init()
{
    popupWin = window.open('https://live.ipms247.com/login/','popupWin','');
}
function transferText()
{
    popupText = popupWin.document.getElementById("username");
    parentText = document.getElementById("parentTextBox");
    popupText.value = parentText.value
}
</script>
</head>
<body>
<input type="text" id="parentTextBox" onkeyup="transferText();" value="Hello World">
<input type="button" onclick="init();" value="popup window">
<input type="button" onclick="transferText();" value="Transfer Text">
</body>
</html>

However, this does not work, apparently because my code is on a local file and the website is on another domain.

So my only solution to this problem, so far, is to launch the site with onlick and then focus to it. Press Ctrl+Shift+J to open the console and then paste the commands (I have code which copies them to clipboard) and hit enter.

Is there any possibility to launch the new window with the console open and focus on the console?

I have added a API response to my Discord Bot and want to know how to format this API response into a embed to make it look nice when it gets sent in Discord

Here is my code:

const ifliveService = require("../utils/InfiniteFlightLive")
const ifl = new ifliveService()

module.exports = {
    category: "Userstats",
    description: "Fetches the users states from Discourse.",
    expectedArgs: '<ifc username>',
    minArgs: 1,
    maxArgs: 1,
    callback: async ({channel, args}) => {
        const username = args[0]
        
        const userstats = await ifl.getUserStats(username)
        if(!userstats || userstats.result == []) return "Invalid user"
        return JSON.stringify(userstats.result[0], null, 't')
         }
     }

I want to return that base reply into a embed how would that be possible? Please note I am a bit of a beginner with all of this so I apologize if it is a quick and easy solution.

The function is working on the HTML page but not working from the external JS file and showing this error (‘checkSelection’ is declared but its value is never read). Is there any solution for this?

      document.getElementById("web-section").style.display = "block";
    } else {

I’ve loaded a .tpl preset file into Photoshop CC 2017, the .tpl file is pretty big and after loading it into the Preset manager, most of the brushes were duplicated for some reason. But it works fine in Photoshop CS 6, so I’m pretty sure the file itself is OK. Now I’m trying to delete all the duplicated brushes through Preset Manager, but there’re just too many of them I could not do it manually.

I’m thinking about writing a .jsx script to do that for me. It will go through the Preset Manager with a for loop and remove every duplicated ones. But I’m not familiar with Photoshop scripting. Pls send help!

I made a project called “pixel paint” by javascript with p5js library, but when I run it, that project ran too slow. I don’t know why and how to make it run faster. And here is my code:

let h = 40, w = 64;
let checkbox;
let scl = 10;
let painting = new Array(h);
let brush = [0, 0, 0];
for(let i = 0; i < h; i++) {
  painting[i] = new Array(w);
  for(let j = 0; j < w; j++) {
    painting[i][j] = [255, 255, 255];
  }
}

function setup() {
  createCanvas(w * scl, h * scl);
  checkbox = createCheckbox('Show gird line', true);
  checkbox.changed(onChange);
}

function draw() {
  background(220);

  for(let y = 0; y < h; y++) {
    for(let x = 0; x < w; x++) {
      fill(painting[y][x]);
      rect(x * scl, y * scl, scl, scl);
    }
  }

  if(mouseIsPressed) {
    paint();
  }
}

function onChange() {
  if (checkbox.checked()) {
    stroke(0);
  } else {
    noStroke();
  }
}

function paint() {
  if(mouseX < w * scl && mouseY < h * scl) {
    let x = floor(mouseX / scl);
    let y = floor(mouseY / scl);
    painting[y][x] = brush;
  }
}

I’m learning to react and trying to migrate an app from the react-router v5 to v6. I have an issue with the routing and need to fix that. The UI looks like below:

If I click the title say Airplane or the New Movie button, the code should hit the route <Route path="/movies/:id" element={<MovieForm/>}/> and take me to the MovieForm page.

The code for the App.js is below:

function App() {
    return (
        <React.Fragment>
            <NavBar/>
            <main className="container">
                <Routes>
                    <Route path="/register" element={<RegisterForm/>}/>
                    <Route path="/login" element={<LoginForm/>}/>
                    <Route path="/movies/:id" element={<MovieForm/>}/>
                    <Route path="/movies" element={<Movies/>}/>
                    <Route path="/customers" component={<Customers/>}/>
                    <Route path="/rentals" component={<Rentals/>}/>
                    <Route path="/not-found" component={<NotFound/>}/>

                    <Route path="/" element={<Navigate replace to="/movies" />} />
                    <Route path="/*" element={<Navigate replace to="/not-found" />} />
                </Routes>
            </main>
        </React.Fragment>
    );
}

The MovieForm code is below:

class MovieForm extends Form {

    state = {
        data: {
            title: "",
            genreId: "",
            numberInStock: "",
            dailyRentalRate: ""
        },
        genres: [],
        errors: {}
    };

    schema = {
        _id: Joi.string(),
        title: Joi.string()
            .required()
            .label("Title"),
        genreId: Joi.string()
            .required()
            .label("Genre"),
        numberInStock: Joi.number()
            .required()
            .min(0)
            .max(100)
            .label("Number in Stock"),
        dailyRentalRate: Joi.number()
            .required()
            .min(0)
            .max(10)
            .label("Daily Rental Rate")
    };




    componentDidMount() {
        const genres = getGenres();
        this.setState({ genres });

        const movieId = this.props.match.params.id;
        if (movieId === "new") return;

        const movie = getMovie(movieId);
        if (!movie) return this.props.history.replace("/not-found");

        this.setState({ data: this.mapToViewModel(movie) });
    }

    mapToViewModel(movie) {
        return {

            numberInStock: movie.numberInStock,
            dailyRentalRate: movie.dailyRentalRate
        };
    }


    doSubmit = () => {
        saveMovie(this.state.data);

        this.props.history.push("/movies");
    };



    render() {
        return (
            <div>
                <h1>Movie Form</h1>
                <form onSubmit={this.handleSubmit}>
                    {this.renderInput("title", "Title")}
                    {this.renderSelect("genreId", "Genre", this.state.genres)}
                    {this.renderInput("numberInStock", "Number in Stock", "number")}
                    {this.renderInput("dailyRentalRate", "Rate")}
                    {this.renderButton("Save")}

                        onSort={this.handleSort}

                    <Pagination

                </div>
            </div>
        );
    }
}

export default Movies;

If you look closely in the class above, the New Movie button is there –

                    <Link
                        to="/movies/new"
                        className="btn btn-primary"
                        style={{ marginBottom: 20 }}
                    >
                        New Movie
                    </Link>

Now, how do I make sure that the route <Route path="/movies/:id" element={<MovieForm/>}/> is working correctly in the react-router v6?

Thanks.
