HomeBackend DevelopmentPHP Tutorial限制ckeditor上传图片文件大小的方法_PHP

FCKEditor

一种可以通过修改PHP.INI配置文件上传大小来限制,另一种方法只能手动修改Fckeditor源码,方法如下
打开editor/filemanager/connectors/php目录下config.php,创建Config变量设置上传图片大小,这里以KB为单位
1、$Config['MaxImageSize']= '1024';
2、打开editor/filemanager/connectors/php目录下commands.php,找到
复制代码 代码如下:
if ( isset( $Config['SecureImageUploads'] ) )
{
if ( ( $isImageValid = IsImageValid( $oFile['tmp_name'], $sExtension ) ) === false )
{
$sErrorNumber = '202' ;
}
//上传图片大小限制
}
在上传图片大小限制处,添加
if ( isset( $Config['MaxImageSize'] ) )
{
$iFileSize = round( $oFile['size'] / 1024 );
if($iFileSize > $Config['MaxImageSize'] )
{
$sErrorNumber = '204';
}
}
 
说明:由于PHP计算上传图片大小以字节为单位,所以代码首先将上传的图片大小折算为KB,再来对比是否超出了规定的图片大小,如超出,则报错。
注意最后将
复制代码 代码如下:
if ( !$sErrorNumber && IsAllowedExt( $sExtension, $resourceType ) )
{
//Fckeditor上传图片功能
}
else
$sErrorNumber = '202' ; 

代码块结尾处的else语句去除,否则实现不了限制Fckeditor上传图片文件大小的功能。
3、打开editor/dialog/fck_image/fck_image.js,添加错误代码(errorNumber)信息,找到OnUploadCompleted函数,添加
复制代码 代码如下:
case 204 :
alert( "Security error. File size error." ) ;
return ; 

至此限制Fckeditor上传图片文件大小配置就完成了,其他类型的上传文件大小限制也是这种思路。

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
