This article will introduce to you the configuration of renaming and adding watermarks to upload files using ckeditor. Students who need to know more can refer to it.
First: I want the uploaded files to be organized into folders based on date
Please modify the config.php file in the editoreditorfilemanagerconnectorsphp folder
The following content was found:
The code is as follows | Copy code | ||||||||
$Config['UserFilesPath'] =
|
was changed to:
The code is as follows | Copy code |
// Path to user files relative to the document root. $Config['UserFilesPath'] = '/uploadfiles/'.date("Ym")."/" ; |
The uploaded files will be stored according to date.
代码如下 | 复制代码 |
// Do a cleanup of the file name to avoid possible problems function SanitizeFileName( $sNewFileName ) { global $Config ; $sNewFileName = stripslashes( $sNewFileName ) ; // Replace dots in the name with underscores (only one dot can be there... security issue). if ( $Config['ForceSingleExtension'] ) $sNewFileName = preg_replace( '/.(?![^.]*$)/', '_', $sNewFileName ) ; // Remove / | : ? * " < > $sNewFileName = preg_replace( '/\|/|||:|?|*|"|<|>/', '_', $sNewFileName ); return $sNewFileName ; } |
Please modify the io.php file in this folder
代码如下 | 复制代码 |
// Do a cleanup of the file name to avoid possible problems function SanitizeFileName( $sNewFileName ) { global $Config ; $sNewFileName = stripslashes( $sNewFileName ) ; // Replace dots in the name with underscores (only one dot can be there... security issue). if ( $Config['ForceSingleExtension'] ) $sNewFileName = preg_replace( '/.(?![^.]*$)/', '_', $sNewFileName ) ; $sExtension = substr( $sNewFileName, ( strrpos($sNewFileName, '.') + 1 ) ) ; $sNewFileName = my_setfilename().'.'.$sExtension; return $sNewFileName ; } function my_setfilename(){ $gettime = explode(' ',microtime()); $string = 'abcdefghijklmnopgrstuvwxyz0123456789'; $rand = ''; for ($x=0;$x<12;$x++) $rand .= substr($string,mt_rand(0,strlen($string)-1),1); return date("ymdHis").substr($gettime[0],2,6).$rand; }

Fckeditor upload image file name duplicate name and Chinese garbled solution
After testing, Fckeditor 2.6.6 did not solve the problem of the Chinese name of the uploaded file becoming garbled. This is because Fckeditor did not rename the file when implementing the upload function, which easily led to the problem of duplicate names and garbled characters for uploaded image files.
The solution to uploading image files with duplicate names and garbled characters is as follows
Open commands.php in the editor/filemanager/connectors/php directory, find the FileUpload function, in
The code is as follows | Copy code | ||||
$sExtension = strtolower( $sExtension ) ; Add after $sFileName = rand(0,100).".".$sExtension; |
The rand function here can change the renaming rules as needed.
Another solution to the garbled file name of the uploaded image is to use the iconv function to convert the file name, but there is still a problem of duplicate names, so it is best to rename the file name of the uploaded image to Fckeditor.
Fckeditor uploads pictures to add watermark function
It is essential for website owners to protect the copyright of images and add watermarks. We can use the PHP watermark function combined with the Fckeditor file upload function FileUpload to implement the image watermark function. For watermark functions, please refer to the PHP image watermark function: Supports the use of images and Add watermark to an article in text mode.
The code is as follows | Copy code |
function setWater($imgSrc,$markImg,$markText,$TextColor,$markPos,$fontType,$markType) $srcInfo = @getimagesize($imgSrc); |
