#Getting Started

HTTP Fields provides a quick interface for working with custom fields within an HTTP request.

To get started, create an HTTP field using the galaxy CLI.

php galaxy make:fields MyFields

This will generate the following unser app/Http/Fields/MyFields:

<?php  
namespace App\Http\Fields;  
  
use TypeRocket\Http\Fields;  
  
class MyFields extends Fields  
{  
    /** @var bool Validate & redirect on errors immediately */  
    protected $run = null;  
  
    /**  
     * Extend the fillable fields of a model
     * these fields are used with.
     * 
     * @return array 
     */
    protected function fillable() {  
        return [];  
    }  
  
    /**
	 * Validator rules these fields must
	 * pass.
	 *
     * @return array 
     */  
     protected function rules() {  
        return [];  
     }  
}

#Within a Controller

You can then use the fields within a controller. For example, you could use the field to get the field used on a POST request:

tr_route()->post()->on('submit', function(\App\Http\Fields\MyFields $fields) {  
    (new \App\Models\Post)->save($fields);  
    return tr_redirect()->back();  
});

#Execute Validation and Redirect

To run field validation and redirect with errors use the fields class methodvalidate() and the validator classes redirectWithErrorsIfFailed(). Running validation and redirecting before saving data will allow the validation to exit before saving if there are validation errors.

tr_route()->post()->on('submit', function(\App\Http\Fields\MyFields $fields) {
    $fields->validate()->redirectWithErrorsIfFailed()
    (new \App\Models\Post)->save($fields);  
    return tr_redirect()->back();
});

#Auto Execute And Redirect

When a fields class, like MyFields, is imported into a controller you can force the field class to automatically validate based on its rules. To auto execute and redirect set the fields class' $run property to true.

If you want to modify the redirect add a redirect() method to the field class.

public function redirect(\TypeRocket\Http\Redirect $redirect)
{
    $redirect->toHome();

    return $redirect;
}
