As this practice is not secured and can be taken advantage by hackers so use it on your own risk.

To make it a bit difficult for them we can ask for primary key and other parameters to ensure some sort of validation.

Auth::login($user)  is used to manually login the user. Where $user is the eloquent collection response of user table

public function userManualLogin(Request $request)
{
   $user = User::where('email', $request->email)->first();

	//any form of validation in if clause

	if ($user->id == $request->id) {
		Auth::login($user);
		return redirect('/user/dashboard');
	}

	if ($this->hasTooManyLoginAttempts($request)) {
	$this->fireLockoutEvent($request);

	return $this->sendLockoutResponse($request);
	}

	$this->incrementLoginAttempts($request);

	return $this->sendFailedLoginResponse($request);
}

$collection = collect();
$collection->merge(['col1' => $col1, 'col2' => $col2 ]);

OR

We can just pass those collection while declaring the collection

$collection = collect([
        'col1' => $col1,
        'col2' => $col2
    ]);

Some Example case

Sometimes we need to get different collection from same Database Table depending on a particular column but we don’t know the no of collections

Then we merge those collection together in a parent collection.

So for e.g. we need users by different city

// this data source can be a static array 
// or a dynamic collection
$states = [
            'Delhi', 
            'Tamil Nadu', 
            'Uttar Pradesh', 
            'Haryana', 'Maharashtra', 
            'Punjab', 
            'Rajasthan', 
            'Bihar'
        ];

// collection helper used to define new Collection
$stateUser = collect();

foreach ($states as $state)
{
    // getting user by a particular city with status 1
    $data = DB::table('user')
        ->select('user.*')
        ->where("user.city", $state)
        ->where('user.status', 1)
        ->get();

    // merging the collection by the key name of state 
    // if collection is not empty
    if (!empty($data[0])) 
    $stateUser = $stateUser->merge([$state => $data]);
}

“replace()” is a iterative function calling a regex as first parameter and adding callback function as its second parameter we can achieve this.

Regular Expression for Every Word in a String ( /\w\S*/g )

And

Callback function converts first word of every word to Upper case

var text = "how to capitalize first letter of each word in js ?";

function toTitleCase(str) {
    return str.replace(/\w\S*/g, function(txt){
        return txt.charAt(0).toUpperCase() + txt.substr(1).toLowerCase();
    });
}

text = toTitleCase(text);

//output
//How To Capitalize First Letter Of Each Word In Js ?

For es6:

var text = "how to capitalize first letter of each word in js ?";

upperCaseWords = (s => s.toLowerCase().split(" ").map(s => s.charAt(0).toUpperCase() + s.substring(1)).join(" "));
    
text = upperCaseWords(text)

//output
//How To Capitalize First Letter Of Each Word In Js ?

To prevent repeating the code and make it more maintainable we define it as a function in one place.

That is what this blog is about.

Prerequisite

• jQuery
• jQuery Validation Plugin

Create a js file

var $postJobValidation = {
	id: function(e) {
		$("#" + e).validate({
			rules: this.rules,
			messages: this.messages
		})
	},
	set: function(e) {

		if (e) {
			for (t in e) {

				if (e[t].rule)
					this.rules[t] = e[t].rule

				if (e[t].message)
					this.messages[t] = e[t].message
			}
		}
	},
	rules: {
		name: "required",
		email: {
			email: !0,
			required: !0
		},
	},
	messages: {
		name: "PLease Enter Your Name",
		email: {
			email: "Enter Valid Email!",
			required: "Enter Email!"
		},
	}
};

To validate a form with id “form1” and having fiels name and email.

$formValidation.id("form1")

To add rules and message we just need to edit rules and message object in $formValidation

$postJobValidation.set({
	"contact": {
		rule: "required",
		message: "Please Enter Your Contact"
	}
})

Set function iterates through the json provided and adding rules

First we need to define a class in app directory

like app/CustomClass/NewClass.php

<?php
namespace App\CustomClass;

class NewClass
{
    public function __construct(variable1)
    {
        $this->variable1 = $variable1; 
    }
    public function yourMethod(Request $request)
    {
        //code
        return "something";
    }
}

Now we need to define a facade for this class

Firstly we need to edit AppServiceProvider.php

In app/Providers/AppServiceProvider.php

Use class defined in app directory

use App\CustomClass\NewClass;

Add following to boot method

$this->app->singleton("NewClassFacade", function(){
    return new NewClass('in');
});

insert NewClassFacade.php in app directory

<?php

namespace App;

class NewClassFacade
{
    protected static function resolveFacade($name)
    {
        return app()[$name];
    }
    
    public static function __callStatic($method, $arguments)
    {
        return (self::resolveFacade('NewClassFacade'))
            ->$method(...$arguments);
    }
}

To call the facade:

Just add the facade to your controller

use App\NewClassFacade;

And call facade like any static method

$output = NewClassFacade::yourMethod();

Similarly \t for vertical tab

so to print \n just add \ before \n like \\n

similarly for \t it will be \\t

#include <iostream>

using namespace std;

int main()
{
    cout<<"Hello \\n World";

    return 0;
}

//output
Hello \n World  

The post How To print \n in C? appeared first on MaXEster Technologies | Technical Blog.

let the response be:

[{
    "data1": "male",
    "data2": "23",
    "data3": "Delhi",
    "data4": "10+2 or above"
}, {
    "data1": "male",
    "data2": "40",
    "data3": "Delhi",
    "data4": "Diploma"
}, {
    "data1": "male",
    "data2": "31",
    "data3": "Delhi",
    "data4": "Graduation"
}, {
    "data1": "male",
    "data2": "25",
    "data3": "Delhi",
    "data4": "Post Graduation"
}]

let the response is saved in var response

let the place where response is appended is

<div><table id="append"></table></div>

to append the json store in data to “#append”

$("#append").append(response.map(data => `<tr><td>${data.data1}</td><td>${data.data2}</td><td>${data.data3}</td><td>${data.data4}</td></tr>`))

Jquery append function is an iterative function which will call response.map which will call parse json

If you have already installed MongoDB.

If Not go-ahead download from here

var MongoClient = require('mongodb').MongoClient;
//Create a database named "testdb":
var url = "mongodb://localhost:27017/testdb";

MongoClient.connect(url, function(err, db) {
  if (err) throw err;

Node has an inbuilt event module about which you learn in-depth from here, we will use event listener and event emitter method of this class.

const EventEmitter = require('events');

const event = new EventEmitter();

Event Listener

An event listener is a logic which will be executed when an event is emitted. Make sure you have declared Event listener before emitting the event.

event.on('some-event', function() {
  // some logic
});


//es6
event.on('some-event', () => {
  // some logic
});


//with parameter
event.on('some-event', (parameter) => {
  // some logic
});

Event Emitter

Event emitter is used to trigger a specific event listener.

event.emit('some-event', parameter);
