Since its initial\nrelease in 2011, Laravel has experienced exponential growth. In 2015, it became\nthe most starred PHP framework on GitHub and rose to the go-to framework for\npeople all over the world.<\/p>\n\n\n\n

Before using Laravel, make sure you have Composer installed in your machine. You have to install the composer https:\/\/getcomposer.org\/<\/a>.<\/p>\n\n\n\n

Step 1: <\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

composer create-project –prefer-dist laravel\/laravel blog<\/p>\n\n\n\n

Step 2:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

It will take time for install this blog project.<\/p>\n\n\n\n

Step 3:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Step 4:<\/p>\n\n\n\n

After installing, go to your project root folder and type PHP artisan serve<\/strong> in the terminal, your project URL might look like this<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Step\n5:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Step 6: Edit .env file for database configuration.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

If you have created the database in MySQL and you have\nprovided correct credentials to the .env<\/strong> file, then\nyou will see there are three tables generated in MySQL database.<\/p>\n\n\n\n

Step\n7: Create a controller file for our CRUD operations.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Step\n8: Create a model file for CRUD operations.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Step 9: Edit the crud migration file and create the required fields for the database.<\/p>\n\n\n\n

Migration file is\nlocated in blog > database > migrations <\/strong>folder.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Step 10:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Step\n11: Create views for set up a form<\/p>\n\n\n\n

Go to blog > resources > views . <\/strong>Locate into that folder and then create a master<\/strong> view called master.blade.php. A blade <\/strong>is a templating engine used by laravel.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Step 12<\/p>\n\n\n\n

Now create a new folder inside views <\/strong>directory called crud. <\/strong>Go inside that folder and create the following files.<\/p>\n\n\n\n

  1. index.blade.php<\/li>
  2. create.blade.php<\/li>
  3. edit.blade.php<\/li><\/ol>\n\n\n\n

    Step 13: Create a form in\ncreate.blade.php.<\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    Step 14: Setup a route for request handling.<\/p>\n\n\n\n

    Go to the routes\n> web.php<\/strong><\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    Here we have added resource route, and all the functions reside in app > Http > controllers\n> CRUDController<\/strong><\/p>\n\n\n\n

    Step\n15: Edit CRUDController File.<\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    Here we have to return the view when the request hits the route; it will be redirected to this controller\u2019s create method. Our view should be accessible via the following URL the form.<\/p>\n\n\n\n

    Step\n16: Add CSRF token and set the post route of the form.<\/p>\n\n\n\n

    We have put the {{csrf_field()}} in the form so that malicious attacks can not harm our web application.<\/p>\n\n\n\n

    Step 17: Code the store function and use the Crud model to insert the data.<\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    Here we need to create a protected field called $fillable in\nthe Crud model. Otherwise, it will throw a mass assignment exception.<\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    Now, when you fill the title and post field in our form and\nsubmit the form, the new entry will be added to the database. We can confirm it\nby following steps.<\/p>\n\n\n\n

    Step\n17: Code index() function in the CRUDController File.<\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    Step\n18: Need to update index.blade.php.<\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    You will see a table that has the id, title, and post-column with their respective data.<\/p>\n\n\n\n

    Step\n19: Add Edit and Delete Button in the index.blade.php.<\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    Step\n20: Create an edit function to pass the data to the edit view.<\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    Step\n21: Create an edit view.<\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    Here we have used one more hidden field called _method<\/strong>, which will be a PATCH<\/strong> request to\nthe server so that we can update the data very quickly.<\/p>\n\n\n\n

    Step\n22: Code update() in the CRUDController.<\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    Step 23: Create a delete form to delete the data.<\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    Step\n24: Code the destroy() method in the CRUDController.<\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n
