This article will explain in detail the example analysis of valicator verification and classification page function creation of blog project in laravel, the editor thinks it is very practical, so share it with you for reference, hope that you can get something after reading this article.

First, the password modification of the background super administrator and the verification of validation

1) assign a route first

2) write a method

If ($input=Input::all ()) {$rules = ['password'= >' required'];} $validator= Validator::make ($input,$rules)

References to the Validator class

Use Illuminate\ Support\ Facades\ Validator;if ($validator- > passes ()) {echo 'yes';} else {echo' no';}}

3) how to know what is wrong in validator

$validator- > errors ()-> all ()

Position writing method

If ($input=Input::all ()) {$rules = ['password'= >' required']; $validator= Validator::make ($input,$rules)

References to the Validator class

Use Illuminate\ Support\ Facades\ Validator;if ($validator- > passes ()) {echo 'yes';} else {dd ($validator- > errors ()-> all ());}}

An error message.

Array:1 [▼ 0 = > "The password field is required."]

3) because the error message is English, how to translate it into Chinese

$validator= Validator::make ($input,$rules,$massege)

Make also has massege with three parameters

If ($input=Input::all ()) {$rules = ['password'= >' required']; $message= ['password.required'= >' New password cannot be empty']; $validator= Validator::make ($input,$rules,$message)

References to the Validator class

Use Illuminate\ Support\ Facades\ Validator;if ($validator- > passes ()) {echo 'yes';} else {dd ($validator- > errors ()-> all ());}}

4) between 6 and 20 digits of the password

$rules = ['password'= >' required | between:6,20']; array:1 [▼ 0 = > "The password must be between 6 and 20 characters."] $message= ['password.required'= >' New password cannot be empty', 'password.between'= >' New password must be between 6 and 20 digits']

5) the new password and the old password should match confirmed

Change the confirmation password of the page:

Name:password_confrimation$rules = ['password'= >' required | between:6,20 | confirmed']; array:2 [▼ 0 = > "New password must be between 6 and 20 digits" 1 = > "The password confirmation does not match."] $message= ['password.required'= >' New password cannot be empty', 'password.between'= >' New password must be between 6 and 20 digits' password.confirmed'= > 'New password and confirmation password are inconsistent'] Array:1 [▼ 0 = > "New password and confirmation password do not match"]

Second, background article classification list page template import and basic display

1) create a resource controller

Php artisan make:controller Controllers/CategroyController

2) create a resource route

Route::resource ('categroy',' CategroyController')

3) check the resource routing

Php artisan route:list

4) create the corresponding method according to the above table

GET home/category all Category list

Public function index () {}

GET home/category/create add categories

Public function create () {}

PUT home/category/ {category} update classification

Public function update () {}

GET home/category/ {category} displays individual classification information

Public function show () {}

DELETE home/category/ {category} Delete a single category

Public function destroy () {}

GET home/category/ {category} / edit Edit Category

Public function edit () {} POST home/categorypublic function store () {}

5) get the list of all categories. If you interface with the database, you should get model.

Php artisan make:model Models/CategroyModel

Initialize information in the class of the model

Protected $table = 'blog_categroy';protected $primaryKey =' cate_id';public $timestamps = 'false'

6) get the data in the controller method

$categroy = CategroyModel::all (); dd ($categroy)

7) assign template

Return view ('home/categroy/index'); / / the index template of the categroy folder in the home folder

8) assign the data to the template

Return view ('home/categroy/index')-> with (' data',$categroy)

9) read the data in the template

@ foreach ($data as $v) {{$v-> cate_name}} @ endforeach on "valicator validation of blog projects in laravel and sample analysis of category page creation" is the end of this article.
