• Laravel 5.7 login & registration page are not working: refreshing the appropriate pages

  guys! I am new to Laravel, and working on project, using the following technologies: Laravel Framework 5.7.15 XAMPP for Windows 7.2.1 PHP version: 7.2.1 Apache/2.4.29 MySQL: libmysql - mysqlnd 5.0.12-dev

  Everything worked fine: the login, and the registration. And then I wanted to restrict registration to the app. So I found below solution to the problem on StackOverflow: How to disable registration new user in Laravel 5 So I added it to app/Http/Controlers/Auth/RegisterController.php:

  public function showRegistrationForm()
  {
      return redirect('login');
  }
  
  public function register()
  {
  
  }
  

  After that (or may be something else, but I am not sure) the login page redirects to login page without logging in to the system. Similarly, registration page (which I remember was redirecting to the login page) is also refreshing the page without registering me to the system.

  What I did to solve the problem: 1) I removed the above methods from the file. The pages do not work as intended. Both pages refresh and do not give any errors. 2) I removed my database and migrates again. No results.

  I just do not want to recreate the project because of this problem, and I hope that someone can help.

  Thanks a lot!

• Laravel 5.7, do something before user logout

  I wanted to set the current user type field to something else before logout but the problem is, I don't know which controller or which method I should put this code at. Btw, I don't have AuthController in Laravel 5.7.

• Passing different values between multiple functions in C?

  I'm having trouble passing differing values between multiple functions. That is, i'm trying to have two functions take user inputs, and then have both of those inputs passed to a third function that calculates those inputs added together. Afterwards, it passes that total on to another function that calculates the true total. Finally, after that, the last function displays the final number. I can't seem to figure out how to make multiple functions pass though.

  # include <stdio.h>
  # include <stdlib.h>
  
  int carLength(int userInput) //Length
  {
  int length = 0;
  do
  {
      printf("\nPlease input the length of the area being carpeted:");
      scanf("%d", &userInput);
  } while (length = 0);
  length = userInput; //Essentially using this to store user input so i can 
  use it later.
  return length;
  }
  
  int carWidth(int userInput) //Width
  {
  int width = 0;
  do
  {
      printf("\nPlease input the width of the area being carpeted:");
      scanf("%d", &userInput);
  } while (width = 0);
  width = userInput; //Same as width
  return width;
  }
  
  int carCalculate(int cost) //cost
  {
  int width = userInput;
  int cost = (width * length) * 20;
  return cost;
  }
  
  float cardiscount(float discount) //discount
  {
  float discount = cost - (cost * .1);
  return discount;
  }
  
  float displaydisc(float discount) //discount
  {
  printf("\nThe total cost is: %f\n", discount);
  return discount;
  }
  
  int main()
  {
  int length = 0;
  int width = 0;
  int cost = 0;
  int discount = 0;
  do {
      length = carLength;
  } while (length == 0);
      do {
          width = carWidth;
      } while (carWidth == 0);
      do {
          cost = carCalculate;
      } while (cost == 0);
      do {
          discount = cardiscount;
      } while (discount == 0);
      do {
          displaydisc;
      } while (discount > 0);
      printf("\n Thank you for using this program!");

• Unix bash script for analyzing directory size

  I am writing a simple bash script to determine the directory size. I know this is a very easy task by simply using du -sh directory_name.

  I am trying to learn how to use for loops, while loops, if statements to accomplish this task. Here is my code:

      #while the directory size is less than 1
      while [ -d "$varDirectory" ] && $(du -sh $varDirectory) -lt "$minimumsize"
      do
          echo "$varDirectory is less than 1kb"
          exit
      done
      #for the directory, display the size in human readable format.
      for $varDirectory  
      do
          du -sh $varDirectory
      done
  
  }
  

  What it basically is suppose to do is check if the user input of the directory exists, if not then display it does not. Then use a while loop to check if the size is greater than 1 and display that it is greater than 1. Lastly, use the for loop to display the file size.

  I get an error: syntax error near unexpected token `}'

  OUTPUT

      Please enter a directory

• Object.values not supported in IE - [solution] Object.keys

  So since Object.values is not supported in IE, this is what I did to get it working:

  const activityType = Object.keys(activityType).map((k) => activityType[k]);
  const qualityType = Object.keys(qualityType).map((k) => qualityType[k]);
  
  objTypes.forEach(activityType => {
     viewTypes.forEach(qualityType => {
        qna[activityType + qualityType] =  activityType + '.' + qualityType;
     });
  });
  

  Works fine on IE now. My question is for suggestions on cleaner/sleeker implementation.

• Angular 5 - update and forEach only on the first items

  I'm trying to run two functions, calculoDes() and desempenhos(), in Angular 5, but weird behavior occurs as a result.

  The first function performs a calculation on some phases, always generating an Array of objects for the next step. The steps are commented (maybe the problem is how I do this function, although it works):

  calculoDes(){
        // each query item of 'ficha' creates a keyarray array and uses data to compute the quotient (quociente)
        this.fichas.subscribe(res => {
          res.forEach(item => {
            this.keyArray.push(item.$key);
            this.quocienteCidade = +(((item.cap_cilindrica/100)+(item.quant_marchas/2)+(item.largura/100)+(item.comprimento/1000)+(item.entre_eixos/1000)+(item.peso_seco/10))*-1).toFixed(5);
            this.desCidade.push({quociente: this.quocienteCidade, id: item.$key});
          });
  
          // The 'desCidade' object must be ordered by the quotient value, using the sortOn()
          this.sortOn(this.desCidade, "quociente");  
  
          // The 'range' is calculated by dividing 100 by the total amount of items
          this.range = 100/this.desCidade.length;
  
          / * Performance (desempenhoCidade) is calculated from an "equivalence" between each position in the array 'deCidade' and the percentage that it represents. The largest will always be 100. Stores on object 'desCidade2' * /
          for (var i = 0; i < this.desCidade.length; i++) {
            this.desempenhoCidade = +(100-((i+1)-1)*this.range).toFixed(1);
            this.desCidade2.push({desempenhoCid: this.desempenhoCidade});
          }
  
          //Merge between two Arrays: 'desCidade' e 'desCidade2'
          this.desCidade3 = _.merge(this.desCidade, _.map(this.desCidade2, this.getDesempenho));
  
          // Returns the previous sort, but with the already calculated performance
          this.resultCidade = this.sortTwo(this.desCidade3, this.keyArray, 'id');
          // retrieve only performance (desempenhoCid)
          this.resultCidade = this.resultCidade.map(a => a.desempenhoCid);    
        });
      }
  
  
  
    //sort using the $ key property, sortOn is for NEGATIVES, AS 'CIDADE'
     sortOn (arr, prop) {
       arr.sort ((a, b) => {
            if (a[prop] > b[prop]){
                return -1;
            } else if (a[prop] < b[prop]){
                return 1;
            } else {
            return 0;   
            }
          }
      );
    }
  
  // order an array of objects in the order of an array
  sortTwo (array, order, key) {
    array.sort ((a, b) => {
      var A = a[key], B = b[key];     
      if (order.indexOf(A) > order.indexOf(B)) {
        return 1;
      } else {
        return -1;
      }       
    });  
    return array;
  };
  
  // Lodash to merge between two Arrays, including the property below
  getDesempenho(el) { 
    return _.pick(el, 'desempenhoCid'); 
  }
  

  I call this function in ngOnInit() and the results are as expected.

  From the results of this function, I need to use both arrays (keyArray and resultCidade) to update a data in Firebase (using AngularFire):

  desempenhos(){
        this.keyArray.forEach(keyItem => {
          this.db.object('ficha/' + keyItem).update({
            // the item to be updated
            des_cidade: this.resultCidade[0]
          });
          // to each $key, I use the first position of the array and then I exclude it
          this.resultCidade.shift();
        })
      }
  

  The problem is that this function only performs correctly on the first items, but then strangely returns to the function calculoDes() and becomes like a loop over loop (considering both functions!).

  I have already searched it, I have redo it, but I could not find out where the error is between functions.
• How to determine when a child iframe element is within the visible area of a scrolling div?

  I have a scrolling div that may or may not contain one or more iframes who's contents should only be loaded when the iframe is either partly/fully visible between the parent div's scroll area's top and bottom. However, when there are iframes in the div and when I inspect my web-page in Chrome, I see that the iframe's offsetTop values don't change as the parent div's scroll-bar is scrolled upward or downward. Also, I see that the offsetParent of the iframes references the body element rather than the scrolling div that actually contains the iframes.

  Here is a simple web-page that shows the basic div and nested iframe structure that I'm talking about:

  <!DOCTYPE html>
  <html>
    <body>
      <!-- Scrolling div -->
      <div id="scroller" style="height:316px; width: 322px; overflow-y:scroll;">
        <!-- 5 iframes that each contain an img tag that is ignored -->
        <iframe><img id="img" src="1.png"></iframe><br />
        <iframe><img id="img" src="2.png"></iframe><br />
        <iframe><img id="img" src="3.png"></iframe><br />
        <iframe><img id="img" src="4.png"></iframe><br />
        <iframe><img id="img" src="5.png"></iframe><br />
      </div>
      <script>
        //
        // Assign an onScroll function to the scroller div that monitors the div's
        // scrolling ...
        //
  
        function scrollerDivScrolling() {
          var div = scrollerDivScrolling.div;
  
          //
          // The following code only changes the div's background color when the
          // div's scroll-bar is scrolled: white when less-than or 50px or
          // yellow when more 50px.
          //
  
          if( div.scrollTop > 50 ) {
            div.style.backgroundColor = "yellow";
          }
          else {
            div.style.backgroundColor = "white";
          }
  
          //
          // This is code needs to check each of the iframe's position to
          // see if the iframe is displayed partially/fully between the
          // parent div's scroll area's top and bottom, and if so then the
          // iframe's content is set to the html statement(s) that are
          // between to iframe's opening and closing tags.  If the iframe's
          // position is either completely above top of the parent div's
          // scroll area or completely below the parent div's scroll area,
          // then remove the contents.
          //
  
        }
        scrollerDivScrolling.div          = document.getElementById( 'scroller' );
        scrollerDivScrolling.iframes      = scrollerDivScrolling.div.getElementsByTagName( 'iframe' );
        scrollerDivScrolling.div.onscroll = scrollerDivScrolling;
  
        // Initialize the iframes with in the scroller div to 'show' their contents ...
  
        for( var i = 0, iframes = scrollerDivScrolling.iframes, l = iframes.length, iframeDoc = null; i < l; ++i ) {
  
          iframeDoc = iframes[ i ].contentWindow.document;
          iframeDoc.open();
          iframeDoc.write('Test' + ( i + 1 ) );
          iframeDoc.close();
  
        }
      </script>
    </body>
  </html>
  

  As shown in the above code, the iframes are actually loaded with "Test " followed by a number, rather than the image tag statement that is within the individual iframe tags, but this isn't an issue, as I know how to do this already. More importantly, the scrollerDivScrolling() function that handles scrolling the div doesn't actually change the content of each iframe depending on its position relative to the parent div's scroll-area's top and bottom, because I haven't figured out which properties of each iframe I need to use.
• WKWebView open Tabs in Safari not in WebView

  I have got a little problem. I've made a webview app for my website. All is working fine instead of loading links with target="_blank". They re loading in Safari. I want them to be load in the webview. Anyone knows how to do that?

  Here is my code

  import UIKit
  import WebKit
  
  class ViewController: UIViewController, WKUIDelegate {
  
      @IBOutlet weak var WebView: WKWebView!
      override func viewDidLoad() {
          super.viewDidLoad()
          self.WebView.uiDelegate = self
  
          //Lade Webseite https://www.street-grinders.de
          let url = URL(string: "https://www.street-grinders.de")
          let request = URLRequest(url: url!)
  
          //Lade Webview
          WebView.load(request)
  
          //Gestensteuerung aktivieren
          WebView.allowsBackForwardNavigationGestures = true
  
          //Lade die Seite neu wenn Push Down
          let refreshControl = UIRefreshControl()
          refreshControl.addTarget(self, action: #selector(reloadWebView(_:)), for: .valueChanged)
          WebView.scrollView.addSubview(refreshControl)
  
      }
  
      //Öffnet Safari, wenn neuer Tab beansprucht wird!
      func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {
          if navigationAction.targetFrame == nil {
              UIApplication.shared.open(navigationAction.request.url!, options: [:])
          }
          return nil
      }
  
      //Gibt Speicherwarnung
      override func didReceiveMemoryWarning() {
          super.didReceiveMemoryWarning()
  
      }
  
      //Funktion zum Seite neu laden!
      @objc func reloadWebView(_ sender: UIRefreshControl) {
          WebView.reload()
          sender.endRefreshing()
  
      }
  
  }
  

  If someone can post the code instead of the func webView it would be very nice.
• Javascript load more images of the array onclick. Using Firebase

  I'm trying to make my website a little bit faster, and for that, I'm trying to make a button that on each click presents more images. For example: a user can see 5 images, and if the user wants to see 5 more he can, by clicking on the button.

  So for now only got this, and i really think it's not the right way.

  HTML ->

  <ion-card *ngFor="let pic of photoList">
      <h1>{{pic?.username}}</h1>
      <h2>{{pic?.name}}</h2>
      <img src={{pic?.picture}}>
  </ion-card>
      <button ion-button (click)="load()">Load More Images</button>
  

  Js ->

  load() {
      firebase.database().ref('HomeList').limitToLast(5).on('value', snapshot => {
        this.photoList = [];
        snapshot.forEach(snap => {
          this.photoList.push({
            id: snap.key,
            name: snap.val().name,
            username: snap.val().username,
            picture: snap.val().picture,
            email: snap.val().email,
            uid: snap.val().uid,
            rating: snap.val().rating
          });
          console.log(this.photoList);
          return false
        });
        return this.photoList.reverse();
      });
    }
