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
