The yii2 search box can be implemented using the select2 component and the select2 jQuery plug-in composed of a Yii2 enhancement package.
The select2 jQuery plug-in consists of select2 components and a Yii2 enhancement package. This input control is a jQuery-based alternative to the select box. It supports searches, remote datasets, and infinite scrolling of results.
This component is designed specifically for bootstrap 3 style and provides some improvements. If the browser does not support jQuery, the component even works with a normal HTML selection or input text. The most commonly used scenario is to automatically enter keywords and match selections when there is too much drop-down content.
The usage effect is as follows:
composer require kartik-v/yii2-widget-select2 "@dev"or add the following code to the require location in the composer.json file in the root directory
"kartik-v/yii2-widget-select2": "@dev"Note: composer has not been updated for a long time, please update composer self-update first Usage
use kartik\select2\Select2; // Normal select with ActiveForm & model echo $form->field($model, 'state_1')->widget(Select2::classname(), [ 'data' => $data, 'language' => 'de', 'options' => ['placeholder' => 'Select a state ...'], 'pluginOptions' => [ 'allowClear' => true ], ]); // Multiple select without model echo Select2::widget([ 'name' => 'state_2', 'value' => '', 'data' => $data, 'options' => ['multiple' => true, 'placeholder' => 'Select states ...'] ]);PHP Chinese website has a large number of free

In the MVC framework, the mechanism for the controller to render views is based on the naming convention and allows explicit overwriting. If redirection is not explicitly indicated, the controller will automatically find a view file with the same name as the action for rendering. 1. Make sure that the view file exists and is named correctly. For example, the view path corresponding to the action show of the controller PostsController should be views/posts/show.html.erb or Views/Posts/Show.cshtml; 2. Use explicit rendering to specify different templates, such as render'custom_template' in Rails and view('posts.custom_template') in Laravel

When saving data to the database in the Yii framework, it is mainly implemented through the ActiveRecord model. 1. Creating a new record requires instantiation of the model, loading the data and verifying it before saving; 2. Updating the record requires querying the existing data before assignment; 3. When using the load() method for batch assignment, security attributes must be marked in rules(); 4. When saving associated data, transactions should be used to ensure consistency. The specific steps include: instantiating the model and filling the data with load(), calling validate() verification, and finally performing save() persistence; when updating, first obtaining records and then assigning values; when sensitive fields are involved, massassignment should be restricted; when saving the associated model, beginTran should be combined

The method of creating custom operations in Yii is to define a common method starting with an action in the controller, optionally accept parameters; then process data, render views, or return JSON as needed; and finally ensure security through access control. The specific steps include: 1. Create a method prefixed with action; 2. Set the method to public; 3. Can receive URL parameters; 4. Process data such as querying the model, processing POST requests, redirecting, etc.; 5. Use AccessControl or manually checking permissions to restrict access. For example, actionProfile($id) can be accessed via /site/profile?id=123 and renders the user profile page. The best practice is
