How Do You Loop With Blade Directives? Blade directives have proven to be useful in the previous few articles, however, only now will they begin to shine. Loops can look quite messy with PHP when they’re embedded inside of HTML. Blade makes them look nice, almost like they belong there. Read the previous article on IF and SWITCH Blade Directives. Blade has your standard loops, like the for, foreach and while loops, but it also has another one called forelse. I’m going to assume that you know about the various different loops in PHP. If you don’t, take a look at my PHP articles on them.

Create IF and SWITCH Statements With Blade Displaying data is one thing, but Blade has directives such as PHP’s if and switch statements. Blade directives are just shortcuts for implementing PHP code. You can even create your own Blade Directives, and we’ll look at that much later. For now, let’s focus on the built in ones: @if and @switch. Read the previous article on Displaying Data in Blade Files. @if Directive As mentioned above, blade directives replicate actual PHP code. The regular PHP way of writing an if statement is: <?php if ($something == true) { // Do something here } PHP also has the elseif and else statements that pair up with
Discussing Blade Directives We ended our previous article with a quick introduction into Blade. What we really wanted to achieve was introduce what Blade is, understand that there are Blade Directives, and figure out how to load our blade component once a specific route is hit. Read the previous articles on Blade Introduction. In this article, we go deeper. We’re going to look at the following concepts: Displaying Data Displaying Unescaped Data Displaying Data We looked at passing data in the previous article, but we’re going to review it once more. Let’s create a route and pass data to our
Using the Blade Engine to Remove PHP Blade is a templating engine that allows you to write some front-end friendly code. The last thing that the designer wants to see is PHP wrapped up inside of the views. Looking at Blade components, you’ll quickly appreciate the elegance in the appearance vs the mess that PHP can create when used outside of the backend. Blade templates are compiled into PHP code, but we don’t need to worry about it. As long as we use the correct tags, Laravel/Blade will take care of this for us. .blade.php In order to use the
Organize Your Views Better With Subdirectories There are a couple of more concepts that we should look at before we move on to the blade templating engine. This time, we’ll cover subdirectories and one simple check to see if the view that we’re calling actually exists. Read the previous article on Passing Arguments to Views. Subdirectories Who cares about subdirectories? Why not just shove all of the views under one directory, views? It’s incredibly important for organization. Most of the time, you’ll list your resource name, likes users as a subdirectory of views, and then the 4 CRUD views: create.blade.php edit.blade.php index.blade.php show.blade.php
How to Pass Arguments to Views We know how to grab URL parameters and return them from our route, but how do we pass arguments to the view? Read the previous article to see how to pass arguments via the url. It’s a pretty simple thing to implement. Before we look at our route, let’s create a new blade file in the resources/views/ directory called car.blade.php. <!DOCTYPE html> <html lang=”{{ str_replace(‘_’, ‘-‘, app()->getLocale()) }}”> <head> <meta charset=”utf-8″> <meta name=”viewport” content=”width=device-width, initial-scale=1″> <title>Car</title> <!– Fonts –> <link href=”https://fonts.bunny.net/css2?family=Nunito:wght@400;600;700&display=swap” rel=”stylesheet”> <!– Styles –> <style> /*! normalize.css v8.0.1 | MIT License | github.com/necolas/normalize.css */html{line-height:1.15;-webkit-text-size-adjust:100%}body{margin:0}a{background-color:transparent}[hidden]{display:none}html{font-family:system-ui,-apple-system,BlinkMacSystemFont,Segoe UI,Roboto,Helvetica Neue,Arial,Noto
Pass Parameters to Your Laravel Route We ended our last article talking about basic routing and views. Frequently we need to pass arguments to our route file via URL parameters. If you’re familiar with PHP, you know that to capture an argument like https://example.com/results.php?page=4, we need to use the $_GET global array, i.e. $_GET[‘page’]. Passing a Single Argument In Laravel, we can pass arguments to the route file just as simply. <?php use Illuminate\Support\Facades\Route; Route::get(‘/about/{name}’, function ($name) { return $name; }); To declare a parameter, we need to surround the url parameter with curly braces. In the example above, we are expecting a “name.”
How To Route in Laravel It’s a difficult thing when it comes to thinking how to approach the learning process. I’m not a big fan of learning a specific concept, like Controllers, right away. I believe that you learn the best by moving slowly through the concepts. I’ll try to present these concepts in a strategic order. Hopefully it works for you. The purpose of this article is to see how we would normally get to a specific view. The only view that we have currently is the welcome view. If we wanted to modify what the user sees right now, what
A Visual Guide to Directory Structures Where do you put your files? How does Laravel know? These are a few questions that I normally get from individuals just starting out with Laravel, or really any other framework. Laravel creates a folder structure for you and it expects certain files to appear in specific places. If they’re not there, Laravel will not know what to do. It expects your controllers to be in the Http folder, it expects your models to be in the Models folder, etc. If you’re not familiar with those concepts yet, don’t worry, we’ll cover each of them
Get Ready to Docker Closing down the PHP project today felt a little sad. It’s a series that I’ve been working on for quite some time now and finally felt like I’ve exhausted the subject. I’ll probably continue with some more advanced topics since I don’t want it to end. As I write that, I feel a little better about it now. Let’s continue with my absolute favorite framework, Laravel. We briefly looked at the installation process in the previous article, and to be honest, it’s about as simple as it gets. There are a few different ways to install
