[laravel] Blog project practical notes-valicator verification and category page function creation

I always want to do a small project by myself, but I don’t know how to start. I always do a certain part of the project when I go to work, and I don’t do a project as a whole. The following is a summary of the videos I watched on the PHP Chinese website. Notes for your reference. This is a practical blog project done in a Windows environment. The following articles are part of the project. I will share them section by section. If you want to see more, follow me and I will continue to update.

1. Modification of the background super administrator password and verification of verification

1) First allocate a route

2)Write a method

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

Reference of Validator class

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

3) How to know what error is in validator

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

Position writing method

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

Reference of Validator class

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

Error message

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

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

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

make also has three parameters massege

if($input=Input::all()){
$rules = [
'password'=>'required'
];
$message=[
'password.required'=>'新密码不能为空'
];
$validator= Validator::make($input,$rules,$message);

Validator class Quote

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

4) The password should be between 6-20 characters

$rules = [
'password'=>'required|between:6,20'
];
array:1 [▼
  0 => "The password must be between 6 and 20 characters."]
$message=[
'password.required'=>'新密码不能为空'，
'password.between'=>'新密码必须在6到20位之间'
];

5) The new password and the old password must match confirmed

Change the confirmed password of the page:

name:password_confrimation
$rules = [
'password'=>'required|between:6,20|confirmed'
];
array:2 [▼
  0 => "新密码必须在6位到20位之间"  1 => "The password confirmation does not match."]
$message=[
'password.required'=>'新密码不能为空'，
'password.between'=>'新密码必须在6到20位之间'
'password.confirmed'=>'新密码和确认密码不一致'
];
array:1 [▼
  0 => "新密码和确认密码不一致"]

2. Background article classification list page template import and basic display

1) Create resource controller

php artisan make:controller Controllers/CategroyController

2) Create resource routing

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 category

public function create(){
}

PUT home/category/{category} Update category

public function update(){
}

GET home/category/{category} Display single category 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/category
public function store(){
}

5) Get the list of all categories, and connect to the database to get the model

php artisan make:model Models/CategroyModel

Initialize information in the model class

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

6) Obtain data in the controller method

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

7) Assign template

return view('home/categroy/index');   //home文件夹里categroy文件夹的index模板

8) The data is allocated 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
