Laravel

Laravel is a free, open-source PHP web application framework for the development of web applications following the model–view–controller (MVC) architectural pattern. Some of the features of Laravel are a modular packaging system with a dedicated dependency manager, different ways for accessing relational databases, utilities that aid in application deployment and maintenance, and its orientation toward syntactic sugar. Laravel is regarded as one of the most popular PHP frameworks.

I'm a few months away from starting to take on Freelancing gigs.

I was wondering how to do my books/bill clients.

I had a fantasy about using Laravel to create a separate site on a subdomain that would bill clients and export a CSV. But I've been thinking about using Freshbooks.

I will probably offer subscription services (hosting/maintenance) which I want to bill using the web.

My website will be WordPress.

I'm not sure how to handle billing, and I want to have a good system down when I start. I know that Freshbooks has an API.

What would be the best way to handle this?

Hi Experts

Could you point how to correctly configure PHP to use with Laravel?

After a composer update this error occurs
- laravel/framework v5.2.9 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.

To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php/7.2/cli/php.ini
    - /etc/php/7.2/cli/conf.d/10-mysqlnd.ini

I've been asked to submit a code sample using JQuery and Laravel. It's done and I'm getting ready to zip things up to hand to the administrator but I've got a question.

When I go to zip up the entire Laravel project, the "vendor" and the "node_modules" folders are enormous.

The exercise itself is pretty simple. I think I could get the point across with a couple of blades and the controller. Still, I want them to see the entire site, so here's my question:

Do those who work in Laravel typically expect those two directories? Is there a more streamlined approach to sharing the code to a Laravel site or do you have to box up the whole thing?

Basic question, I know, but it's worth asking if there's a more expeditious way to do things.

I have XAMPP running on Windows 10. I am trying to setup a Virtual Host so that when I use "myapp.dev" as a domain I get directly to my public folder of laravel project.
Laravel is located at C:/xampp/htdocs/myapp/public.
By using http://localhost:8000/myapp/public/ i can access laravel index.php
So far i have tried the following:
http v-host.conf file
#this is the default address of XAMPP    
<VirtualHost *:8000>
   DocumentRoot "C:/XAMPP/htdocs/"
   ServerName localhost
</VirtualHost>


<VirtualHost *:8000>
    DocumentRoot "C:/xampp/htdocs/myapp/public"
    ServerName myapp.test
    SetEnv NS_ENV variable_value
</VirtualHost>

and in C:\Windows\System32\drivers\etc\host file

127.0.0.1 localhost
127.0.0.1:8000 myapp.test

and after restarting apache and typing myapp.test leads to iis homepage instead of index.php in public folder.

I would like to find out whether is there a way to perform the following:

1) Include (when $id is not null) and exclude (when $id is null) in the where clause for the code below.
2) Switch between sortByDesc and sortBy based on condition ($sort=='asc' then.... $sort=='desc' then...) for the code below.

if($id){
   $maxlimit = Product::where('category_id_fk',$id)->with(['child','price','variant','thumbnail','image','description'])->count();
   $products = Product::where('category_id_fk',$id)->with(['child','price','variant','thumbnail','image','description'])->take($recperpage)->get()->sortByDesc('price.list_price');
}else{
   $maxlimit = Product::with(['child','price','variant','thumbnail','image','description'])->count();
   $products = Product::with(['child','price','variant','thumbnail','image','description'])->take($recperpage)->get()->sortByDesc('price.list_price');

The objective is to simplify the code above as much as possible but achieve the same result.

I am a college student. I have some money I inherited and I was thinking about starting an eCommerce site for vapes and juices.

I wanted some advice to see what platform I should use. To show you where my coding skills are at a project I am working on is available at wookify.com.

I've played around with Woocommerce. I'm intrigued by Magento.

I've also wondered about building an ecommerce site from scratch or with Laravel.

Thanks for your help, if I could make 1k a month I could pay expenses. What do I need to begin researching? Is this a foolish use of my money?

I installed Laravel.

I created a virtual host on my computer with the hostname laravel.local.

When I installed Laravel I chose the name sample-application, and when it installed it, it  created a directory in my public directory that was called sample-application.

My question is really dumb, but because of apache mod rewrite, you won't have to move files around to display a page for laravel.local right?

Hi,
I have a datatables table I am using to allow a person to resort the row order of the slides (see attached as example). In my mysql table I am using an additional column to set the row order of each row.
So essentially in mysql I have
id - primary auto increment
SlideOrder - I am using for the sequence
SlideTitle
and a couple created/modified datetime etc.

 
table example
When the user drops a row into place the code I'm using is below to send to server ( I start getting sketchy here on in):

oTable.on( 'row-reorder', function ( e, diff, edit ) 
{
var result;
var sendloop = [];
 		
	for ( var i=0, ien=diff.length ; i<ien ; i++ )
	{
		var rowData = oTable.row( diff[i].node ).data();
		result = ''+diff[i].newData+','+diff[i].oldData+'';
		sendloop.push(result);
	}
        	
	var jsonString = JSON.stringify(sendloop);
   
$.ajax({
        type: "GET",
        url: "/dealboxx/ohs/admin/sort",
        data: {data : jsonString}, 
        cache: false
    });
    });

Open in new window


The result of which sends an ajax request and the data variable (when I drag row 1 below row 4 for example):
data["1,2","2,3","3,4","4,1"]

Had I dragged row 2 below row 3 initially I'd be sending:
data["2,3","3,2"]

Had I dragged row 3 in front of row 1:
data["1,3","2,1","3,2"]

When the data gets to my server (my wrong code) does this:
public function sortCourse(Request $request)
    {
	$obj = json_decode($request->input('data'), true);
	
	foreach($obj as $row)
	{
     
		$insertArray = explode(",",$row);
		
		$slidechange = DB::table('ohs_courses_content')
			->select('id')
			->where('SlideOrder',$insertArray[1])
		    ->first();
		
    
	DB::table('ohs_courses_content')
            ->where('id', $slidechange->id)
            ->update(['SlideOrder' => $insertArray[0]]);
 	 	}
	
    
    }

Open in new window


Depending on what I initially dragged it may work (if I'm dragging down or up). Couple drags into it and its a mess.

So my logic etc is no doubt totally wrong.

any help would be very much appreciated as always.

I've been taking on the occasional client, undercharging for my hours to meet market rates, but I just discovered Wordpress and I realized I can have enough output (you know for the average site someone wants to have built) and I can charge extra for custom plugins or Laravel or other solutions that require something more than Wordpress.

After 2018 I would like to start taking on clients - I would like to have the following on my portfolio
-Ecommerce site for local business built with Woocommerce
-Ecommerce site built for another local business built with Woocommerce
-consolidatedutilities.com rewritten in Laravel, possibly with a new design
-effinghamministorage.com possibly redone with wordpress
-pwsmeetup.com - a social media site for people with prader willi syndrome written in Laravel
-umstream.net - a streaming audio site for Umphrey's Mcgee written with Laravel and React

Would listing these sites be a good idea or a bad idea? Should I use Google Adwords? How much do I need to save up for advertising when I build a site advertising services?

I'm going to offer hosting and security. I'm studying Cyber Security and I don't know if I should put that.

I have Schizophrenia and Bipolar and it's a lot harder for me to communicate professionally that it is for most people. Presenting myself well will be a challenge, but I know that my work will be good. I have to work very hard at this, it doesn't come naturally to me, at least not since my diagnosis.

I'm not going to mess with Laravel right now, but I want to create a primitive Model View Controller for this site. Can you reference materials on how to build a MVC site?

I am a Cyber Security major. I've done a lot of programming as a hobbyist, and when I got into Java (and later when I looked at Swift) I felt like I was experiencing some major breakthroughs with Object Oriented Programming and PHP.

I have Crohn's so I didn't even complete the first course which only went up to multidimensional arrays.

So now I need some guidance - do I work out of PHP Patterns Objects and Practice before learning a framework? That book covers Object Oriented Design as well as the concepts.

Should I do that or just move to Laravel and start learning that?

What would be best.

A huge question I have about object oriented frameworks are - can you add functionality that's not built into the framework into your application?

When designing a complex website do you want to use an existing framwork or build your own? If you use an existing one and functionality isn't built in how do you add functionality?

I have 5 tables namely product, category, price, inventory and image.

In my product table I have a foreign key column (category_id_fk) referencing to category table primary key column (id). In my product model I have the following function defined:

    public function price(){
		return $this->hasOne('App\Models\Price','product_id_fk');
    }
	
    public function inventory(){
		return $this->hasOne('App\Models\Inventory','product_id_fk');
    }
	    
    public function image(){
		return $this->hasMany('App\Models\Image','product_id_fk');
    }
	
    public function category(){
                return $this->belongsTo('App\Models\Category','id');
    }

In my category model I have the following function defined:

I have performed the following query:

$product = Product::with('price','inventory','image')->get();

The result is it return all records that exist in the product table and associated tables (price, inventory, image) which is correct.

However when I attempt to perform similar action by including the category table

$product = Product::with('category','price','inventory','image')->get();

The result is it return all records that exist in the product table and associated tables (price, inventory, image) but the category record is incorrect (either null or unrelated record).

Hey, guys!

Here's a snippet from a page called "user.class.php:"

 function updateDevices() {
        global $S;
        global $CN;
        date_default_timezone_set('America/Chicago');
        $maxHistory = date('Y-m-d',strtotime("now - 2 weeks"));
        $R = new xajaxResponse();
        $fitBitCalls = array( '/1/user/-/body/weight/date/'.date('Y-m-d').'/'.$maxHistory.'.json',

        '/1/user/-/body/log/weight/goal.json',
        '/1/user/-/body/log/fat/goal.json',
        '/1/user/-/activities/steps/date/today/max.json',
        '/1/user/-/activities/calories/date/today/'.$maxHistory.'.json',
        '/1/user/-/activities/distance/date/today/'.$maxHistory.'.json',
        );
        //See if this user any devices that have not been synced.
        $stmt = $CN->prepare("SELECT * 	FROM hraUserDevices  UD INNER JOIN hraUserDeviceTypes UT  ON UD.udtID = UT.udtID  WHERE usrID = ? AND (DATEDIFF(day,udFetchedLastDate,getdate()) IS NULL OR DATEDIFF(day,udFetchedLastDate,getdate()) >=1) AND (udUpdating IS NULL  OR udUpdating !=1 OR DATEDIFF(day,udFetchedLastDate,getdate()) >=2)");
        $stmt->execute(array($S->usrID));
        $devices = $stmt->fetchAll();
        $update = $CN->prepare("UPDATE  hraUserDevices SET udUpdating = ? WHERE udID = ? ");

Open in new window


The question I have is, "What is $CN?"

Obviously, it's a database connection. My problem is that it's not defined anywhere on the page, nor is EVER defined that I can see anywhere in the app.

You do, however, have this at the top of the same page:

	private $cn; // $cn = VARIABLE HOLDING THE DB CONNECTION

	function __construct(PDO $conn) {
		if (!isset($conn))
			throw new Exception('User objects must be passed a PDO Connection object ($this->cn) upon construction');
		$this->cn = $conn;
	}

Open in new window


Is there a convention that I'm missing? $CN is not equivalent to $cn, and yet throughout the entire app you see repeated references to $CN but I can't find anywhere that $CN is actually defined.

Any ideas?

I'm trying to figure out what the correct way is to modify a date format before inserting when using Laravel 5.4.

I have:
public function store(){

        $trip = new Trip;

        $trip->departing = request('departing');
        $trip->returning = request('returning');
        $trip->save();

        return $trip;

Open in new window


What I am attempting to do is to create a new permission object that has the status true or false.

As shown the data object contains a list of default permission.

The try object on the other hand shows that each module has permission. A module can have 0 or more than 1 permission.  

Now i'm trying to reconstruct the information so that each module has equal number of default permission but based on the try object conditioning (permission) is done to set the status either true or false.

However my code above doesn't do so. Rather a module with is set based on the try object conditioning (permission) and others are set with the default permission and status false.

Your help is kindly appreciated.

Laravel

Laravel is a free, open-source PHP web application framework for the development of web applications following the model–view–controller (MVC) architectural pattern. Some of the features of Laravel are a modular packaging system with a dedicated dependency manager, different ways for accessing relational databases, utilities that aid in application deployment and maintenance, and its orientation toward syntactic sugar. Laravel is regarded as one of the most popular PHP frameworks.
