Yii2
废话不多说了,先给大家展示下效果图,如果大家还很满意请继续往下阅读:
具体怎么实现喃?考虑到一张数据表要下拉效果的字段可能有很多个,我们先在其model中实现一个方法方便后续操作
/** * 下拉筛选 * @column string 字段 * @value mix 字段对应的值,不指定则返回字段数组 * @return mix 返回某个值或者数组 */ public static function dropDown ($column, $value = null) { $dropDownList = [ 'is_delete'=> [ '0'=>'显示', '1'=>'删除', ], 'is_hot'=> [ '0'=>'否', '1'=>'是', ], //有新的字段要实现下拉规则,可像上面这样进行添加 // ...... ]; //根据具体值显示对应的值 if ($value !== null) return array_key_exists($column, $dropDownList) ? $dropDownList[$column][$value] : false; //返回关联数组,用户下拉的filter实现 else return array_key_exists($column, $dropDownList) ? $dropDownList[$column] : false; }
然后我们上代码看看具体怎么实现的下拉搜索
<?= GridView::widget([ 'dataProvider' => $dataProvider, 'columns' => [ // ...... [ 'attribute' => 'is_hot', 'value' => function ($model) { return Article::dropDown('is_hot', $model->is_hot); }, 'filter' => Article::dropDown('is_hot'), ], [ 'attribute' => 'is_delete', 'value' => function ($model) { return Article::dropDown('is_delete', $model->is_delete); }, 'filter' => Article::dropDown('is_delete'), ], // ...... ], ]); ?>
像这样,我们就简单地实现了两个下拉效果,要实现筛选功能,在你的dataProvider自定添加该字段的搜索条件即可。

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
