This article mainly introduces the image upload function of Yii combined with CKEditor. Yii is the famous PHP development framework, and CKEditor is the famous WYSIWYG editor. Friends in need can refer to this
In a project I worked on a few days ago, I needed to implement the image upload function in the WYSIWYG editor. I chose CKEditor because I liked its interface better. Although there is CKFinder that works well with CKEditor, its function is too complicated. After briefly looking at the documentation of CKEditor, I found that this function can be implemented by myself without the help of CKFinder.
Although the following code is based on Yii Framework, the idea is exactly the same when using other frameworks or languages. Children's shoes in need can be referred to.
First of all, to enable the image upload function in CkEditor, you need to configure the filebrowserImageUploadUrl attribute of the editor:
CKEDITOR.replace( 'editor1', { filebrowserUploadUrl : '/uploader/upload.php', filebrowserImageUploadUrl : '/uploader/upload.php?type=Images' });
Then implement the image upload function on the corresponding URL and return a specific format to CKEditor HTML code, CKEditor can preview and insert pictures normally.
Only part of the code of the controller is intercepted below. I implemented the Controller part like this:
/** * 保存上传的图片 * * @return string javascript code * @author lfyzjck **/ public function actionImg($type, $CKEditor, $CKEditorFuncNum, $langCode = 'zh-cn') { if(empty($CKEditorFuncNum) || $type != 'Images'){ $this->mkhtml($CKEditorFuncNum,'','错误的函数调用'); } if(isset($_FILES['upload'])){ //获取关于图片上传配置 $options = Options::model()->findByPk(1); $form = new UploadForm('image',$options); $form->upload = CUploadedFile::getInstanceByName('upload'); if($form->validate()){ //文件名:时间+源文件名 $target_filename = date('Ymd-hm',time()).$form->upload->getName(); $path = Yii::app()->basePath.'/../uploads/'.$target_filename; //图片保存路径 $form->upload->saveAs($path); $this->mkhtml($CKEditorFuncNum,Yii::app()->baseUrl.'/uploads/'.$target_filename, "上传成功"); } else{ $this->mkhtml($CKEditorFuncNum,'',$form->getError('upload')); } } } /** * 返回CKEditor的提示信息 * * @return void * @author lfyzjck **/ private function mkhtml($fn, $fileurl, $message) { $str = ''; exit($str); }
The mkhtml function that needs special explanation will call the CKEditor function to generate prompt information. When the upload is successful, the image link will be returned, and CKEditor will generate an image preview based on the URL.
Then comes the UploadForm code, which will verify whether the format and size of the image meet the requirements.
class UploadForm extends CFormModel { public $upload; private $options; private $type; public function __construct($type, $options){ $this->options = $options; $this->type = $type; } /** * Declares the validation rules. * The rules state that username and password are required, * and password needs to be authenticated. */ public function rules() { return array( array('upload', 'file', 'types' => $this->options->getAttribute("allow_".$this->type."_type"), 'maxSize' => 1024 * (int)$this->options->getAttribute("allow_".$this->type."_maxsize"), 'tooLarge'=>'文件大小超过限制', ), ); } }

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.

Fibers was introduced in PHP8.1, improving concurrent processing capabilities. 1) Fibers is a lightweight concurrency model similar to coroutines. 2) They allow developers to manually control the execution flow of tasks and are suitable for handling I/O-intensive tasks. 3) Using Fibers can write more efficient and responsive code.

The PHP community provides rich resources and support to help developers grow. 1) Resources include official documentation, tutorials, blogs and open source projects such as Laravel and Symfony. 2) Support can be obtained through StackOverflow, Reddit and Slack channels. 3) Development trends can be learned by following RFC. 4) Integration into the community can be achieved through active participation, contribution to code and learning sharing.

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.
