When I’m putting ImageView component within View component, I am getting the error: Error: Text strings must be rendered within a component. I don’t understand what is wrong over here. Below is the code snippet:

import React from 'react';
import { View, Image, ScrollView, TouchableOpacity, Modal, Text } from 'react-native';
import styles from './cameraStyles';
import ImageView from "react-native-image-viewing";

export default ({captures=[], lflagImage=false}) => {
    const [flagImage, setflagImage] = React.useState(lflagImage);
    return (
        <ScrollView horizontal={true} style={[styles.bottomToolbar, styles.galleryContainer]}>
            {captures.map(({ uri }) => (
                <View style={styles.galleryImageContainer} key={uri}>
                    <TouchableOpacity onPress={()=> {setflagImage(prevData => !prevData)}}>
                        <Image source={{ uri }} style={styles.galleryImage}/>                       
                    </TouchableOpacity>
                    <ImageView
                        images={captures}
                        imageIndex={0}
                        visible={flagImage}
                        onRequestClose={() => setflagImage(prevData => !prevData)}
                    />
                </View>
            ))}
        </ScrollView>
    )
}

matrix=[[11, 12, 5, 2],
        [15, 6, 10, 9], 
        [13, 8, 16, 3], 
        [17, 1, 4, 0]]
dig=16

how to get diagonal of 16 from left to right & right to left in top to bottom:

11 6 16 0

9 16 1

so I am creating a game using Phaser 3, with a little treat at the end which is to allow people to customize the characters by selecting the outfits that they want. I am able to finish up the customizing, but now I was wondering if it is possible to have the shirt to always be at the top layer, and the pants to be behind the shirt. You are able to select the shirt or pants first, but whatever is selected second would overlap the first like the image below

I would like for it to be the shirt to always be on top, and the pants to always be below, regardless of whether you select the shirt first or the pants first, like the image below

The code below is the code for when the character has any piece of clothing on. Do help me out if possible I would really appreciate it.

tabs.getElement("panel").on(
      "cell.down",
      function (cellContainer, cellIndex, pointer) {
      console.log(playercoin);
        const name = filter.toLowerCase() + "Image" + cellIndex;
        localStorage.setItem("wa", name);
        let itemToRemove;
        for (let i = 0; i < playerContainer.length; i++) {
          const containerItem = playerContainer.list[i];
          if (containerItem.data.get("name") === filter.toLowerCase()) {
            itemToRemove = containerItem;
            itemToRemove.cost = containerItem.data.get("cost");
            break;
          }
        }
        const costUrl = cellContainer.data.get("costUrl");
        const newCost = GetCostFromUrl(costUrl);

I have a list of data that lists on the collapse, I just want to display in my collapse what i put on my Textfield

const onChangeLocation = (locations) =>{
    console.log(locations)
  }

   <TextField
      size="small"
      fullWidth
      onChange={onChangeLocation}
      variant="standard"
      placeholder="Search Locations"
      onFocus={openSearch}
      value={searchParameter}
      }}
    />

  <Collapse in={viewLocationList} sx={{ my: '2px' }}>
    <Box className="rounded-scrollbar widget-result-container">
      {locations.map((location, index) => (
        <LocationWidgetItem
          key={index}
          location={location}
          onClickLocation={setActiveLocation}
        />
      ))}
    </Box>
  </Collapse>

I have a Player component that maps several song names + images to several Song components.
My Player component code looks like this:

      return (
        <div className="App">
          <div className="main-wrapper">
            {props.foundASong && 
            <div className="song_container">{props.songs.map((object, i) => <Song object={object} key={i} />)}</div>
            }
            <div className="background" style={backgroundStyles} />{" "}
          </div>
        </div>
      );

and my Song code looks like this:

import React, { Component } from "react";

import "./Player.css";
import "./Song.css";

class Song extends Component {
  constructor(props) {
    super(props);
    this.state = {
      clicked: false
    };

    this.changeBackground = this.changeBackground.bind(this);
    this.handleClick = this.handleClick.bind(this);

  }

  handleClick() {
    this.setState(prevState => ({
      clicked: !prevState.clicked
    }));
    console.log("clicked");
  }


  render(props){
    return (
      <div>
        <button onClick={() => this.handleClick}>Click me!</button>
        <div className="song_box"> 
            <img src={this.props.object.album.images[0].url} />
          <div>{this.props.object.name}</div> 
        </div>
      </div>
    );
    }
}

export default Song;

But for some reason, nothing happens when I click any of the buttons. Any ideas why?

I have 5 PHP files, (1.php,2.php,3.php,4.php,5.php) how can I load 1.php for 5 mins, then load 2.php for 5 mins then again 1.php after that 3.php in a specific order.

I have tried it with a button but I want it to do that without buttons just 5 mins then move on

I want to design a calender and display the data from mysql database in django as per the below image:

Any help will be highly appreciated!
Thank You!!

I have the following code which is throwing an error in the Fortify tool:

const headerCopy = (req, resp, next) => {
    if (req.headers["iv-user"]) {
        resp.setHeader("iv-user", req.headers["iv-user"]);
        resp.setHeader("token", process.env.TOKEN);
    }
    if (req.get("referer")) {
        resp.setHeader("referer", req.get("referer"));
    }
    next();
}


app.use(headerCopy, express.static(path.join(__dirname, './build')));

app.get('*', headerCopy, function (req, res) {
    res.sendFile(path.join(__dirname, 'build', 'index.html'));
});

app.listen(port, () => {
    console.log(`MainApp listening at http://localhost:${port}`)
})

The error in the Fortify tool complains with the following msg:

The method headerCopy() in MainApp.js includes unvalidated data in an
HTTP response header on line 11. This enables attacks such as
cache-poisoning, cross-site scripting, cross-user defacement, page
hijacking, cookie manipulation or open redirect.

Can someone please help me with this error?

There is a CKEditor which is implemented well with Strapi Version3 but not able to setup with Version4 of Strapi . Is it possible to implement in version4 or can addon extra components setup with version4 in existing rich text editor ?

Here is the implementation with strapi version 3
[https://strapi.io/blog/how-to-change-the-wysiwyg-in-strapi][1]

In-store I have an array called visited:[]. In a function called changeInfo first I need to clear the array and then add an item to the array.

 const changeInfo = (value) => {
    dispatch(clearVisited());
    console.log("before visited", visited);
    dispatch(addToVisited(value));
    console.log("after visited", visited);
  };

Some can argue that I can have an action type clearAndInsert and reducer like this

 case CLEAR_AND_INSERT:
      return {
        visited: [action.payload],
      };

But this is not wanted I want. I want to dispatch clearVisited and wait until after it clears the array and after that dispatch addToVisited.Want I am getting for the console logs for changeInfo is strange.

HOW CAN I CALL TWO ACTIONS SYNCHRONOUSLY IN REACT?

I am a beginner in web development. I am working on a small project which needs to open a url(something like http://192.168.1.107:8080) content on click of a tab, in the same tab pane. The mentioned url is a client, which displays some runtime data(eg: temperature) continuously.

I could find some code snippets on creating tabs, but I’m keen to get this specific requirement working.

I would appreciate any code snippets, links or information on displaying a url data in same tab pane please.

thanks

I am using the Npm package React data grid https://github.com/adazzle/react-data-grid to bind data.

Issue example
https://codesandbox.io/s/react-data-grid-example-9sb93?file=/src/App.tsx

In a small screen size system or resizing the browser, the right side of the columns started flickering.

Table column flickering only comes in chromium-browser

Does anyone have a solution?

I have tried several ways but I am getting errors that’s why I have pasted the whole code here, also one thing is I have used mobx for state management purposes.

as u can see name topic how do I make the .setImage change every update when i change the image without deleting a msg? or write cmd once again

my first attempt : I tried to make it by uploading the image from a hosting site and to get the image link and from there I change the image and then I used setInterval to update the line .setImage but did not work for me this is my code of first attempt

let exampleEmbed = new MessageEmbed()
        .setColor('#0099ff')
        exampleEmbed.setImage('https://test.000webhostapp.com/images/image.jpg')
        .setTimestamp()

    try {
        let message1 = await message.channel.send({ embeds: [exampleEmbed] });
        setInterval(async function(){
            let exampleEmbed2 = new MessageEmbed()
            .setColor('#0099ff')
            exampleEmbed2.setImage('https://test.000webhostapp.com/images/image.jpg')
            console.log('updated')
            await message1.edit({ embeds: [exampleEmbed2] })
        },7000)

    } catch(err) {
        console.log(err)
    }

my second attempt was from the local computer I used MessageAttachment to get me the file path of image and then I also used setInterval to update the line function inside .setImage + MessageAttachment every 7 seconds it didn’t work either. Although when I type the command again, the (updated) image appears on the second try
here is my codes try second attempt

let exampleEmbed = new MessageEmbed()
        .setColor('#0099ff')
        exampleEmbed.setImage('https://test.000webhostapp.com/images/image.jpg')
        .setTimestamp()

    try {
        let message1 = await message.channel.send({ embeds: [exampleEmbed] });
        setInterval(async function(){
            let exampleEmbed2 = new MessageEmbed()
      const attachement =  new MessageAttachment('./images/image.jpg','image.jpg');
            .setColor('#0099ff')
            exampleEmbed2.setImage('attachment://image.jpg')
            console.log('updated')
            await message1.edit({ embeds: [exampleEmbed2], files: [attachement] })
        },7000)

    } catch(err) {
        console.log(err)
    }

Is there another way please? i would like to do the image update sync in any way without restart the bot or even writing cmd again

making a discord clone, im trying to use the database in firebase but it doesnt seem to be working I keep getting this error, “firebase__WEBPACK_IMPORTED_MODULE_5_.default.collection is not a function” heres my code

    useEffect(() => {
        db.collection('channels').onSnapshot((snapshot) => 
            setChannels(
                snapshot.docs.map((doc) => ({
                id: doc.id,
                channel: doc.data(),
            })) 
          ) 
        );
    }, []);

btw this is how I declared my database in firebase.js

const db = getFirestore(app);

looked around everywhere but I cant seem to find an answer
