最后在把网站编辑器由以前的fck改成UEDITOR编辑器了,但是发现UEDITOR编辑器上传图片是自动提取的,但是图片没有水印功能,下面小编和各位一起来看看.
UEditor编辑器没有上传图片加水印的功能,需要进行二次开发,本例是在PHPCMS系统中对百度编辑器进行二次开发,添加上传图片加水印功能.
首先打开UEditor编辑器文件目录的php文件夹,打开Uploader.class.php,把PHPCMS添加水印的方法复制过来,加到这个类所有成员方法最后面,然后进行修改如下:
- //图片加水印
- public function watermark($source, $target = '', $w_pos = '', $w_img = '', $w_text = '99danji',$w_font = 8, $w_color = '#ff0000') {
- $this->w_img = 'watermark.png';
- $this->w_pos = 9;
- $this->w_minwidth = 400;
- $this->w_minheight = 200;
- $this->w_quality = 80;
- $this->w_pct = 85;
- $w_pos = $w_pos ? $w_pos : $this->w_pos;
- $w_img = $w_img ? $w_img : $this->w_img;
- //if(!$this->watermark_enable || !$this->check($source)) return false;
- if(!$target) $target = $source;
- //$w_img = PHPCMS_PATH.$w_img;
- //define('WWW_PATH', dirname(dirname(dirname(__FILE__)));
- $w_img = '../../../images/water/'.$w_img;
- $source_info = getimagesize($source);
- $source_w = $source_info[0];
- $source_h = $source_info[1];
- //if($source_w < $this->w_minwidth || $source_h < $this->w_minheight) return false;
- switch($source_info[2]) {
- case 1 :
- $source_img = imagecreatefromgif($source);
- break;
- case 2 :
- $source_img = imagecreatefromjpeg($source);
- break;
- case 3 :
- $source_img = imagecreatefrompng($source);
- break;
- default :
- return false;
- }
- if(!emptyempty($w_img) && file_exists($w_img)) {
- $ifwaterimage = 1;
- $water_info = getimagesize($w_img);
- $width = $water_info[0];
- $height = $water_info[1];
- switch($water_info[2]) {
- case 1 :
- $water_img = imagecreatefromgif($w_img);
- break;
- case 2 :
- $water_img = imagecreatefromjpeg($w_img);
- break;
- case 3 :
- $water_img = imagecreatefrompng($w_img);
- break;
- default :
- return;
- }
- } else {
- $ifwaterimage = 0;
- $temp = imagettfbbox(ceil($w_font*2.5), 0, PC_PATH.'libs/data/font/elephant.ttf', $w_text);
- $width = $temp[2] - $temp[6];
- $height = $temp[3] - $temp[7];
- unset($temp);
- }
- switch($w_pos) {
- case 1:
- $wx = 5;
- $wy = 5;
- break;
- case 2:
- $wx = ($source_w - $width) / 2;
- $wy = 0;
- break;
- case 3:
- $wx = $source_w - $width;
- $wy = 0;
- break;
- case 4:
- $wx = 0;
- $wy = ($source_h - $height) / 2;
- break;
- case 5:
- $wx = ($source_w - $width) / 2;
- $wy = ($source_h - $height) / 2;
- break;
- case 6:
- $wx = $source_w - $width;
- $wy = ($source_h - $height) / 2;
- break;
- case 7:
- $wx = 0;
- $wy = $source_h - $height;
- break;
- case 8:
- $wx = ($source_w - $width) / 2;
- $wy = $source_h - $height;
- break;
- case 9:
- $wx = $source_w - $width;
- $wy = $source_h - $height;
- break;
- case 10:
- $wx = rand(0,($source_w - $width));
- $wy = rand(0,($source_h - $height));
- break;
- default:
- $wx = rand(0,($source_w - $width));
- $wy = rand(0,($source_h - $height));
- break;
- }
- if($ifwaterimage) {
- if($water_info[2] == 3) {
- imagecopy($source_img, $water_img, $wx, $wy, 0, 0, $width, $height);
- } else {
- imagecopymerge($source_img, $water_img, $wx, $wy, 0, 0, $width, $height, $this->w_pct);
- }
- } else {
- if(!emptyempty($w_color) && (strlen($w_color)==7)) {
- $r = hexdec(substr($w_color,1,2));
- $g = hexdec(substr($w_color,3,2));
- $b = hexdec(substr($w_color,5));
- } else {
- return;
- }
- imagestring($source_img,$w_font,$wx,$wy,$w_text,imagecolorallocate($source_img,$r,$g,$b));
- }
- switch($source_info[2]) {
- case 1 :
- imagegif($source_img, $target);
- break;
- case 2 :
- imagejpeg($source_img, $target, $this->w_quality);
- break;
- case 3 :
- imagepng($source_img, $target);
- break;
- default :
- return;
- }
- if(isset($water_info)) {
- unset($water_info);
- }
- if(isset($water_img)) {
- imagedestroy($water_img);
- }
- unset($source_info);
- imagedestroy($source_img);
- return true;
- }
- public function check($image) {
- return extension_loaded('gd') && preg_match("/\.(jpg|jpeg|gif|png)/i", $image, $m) && file_exists($image) && function_exists('imagecreatefrom'.($m[1] == 'jpg' ? 'jpeg' : $m[1]));
- }
对比我修改的部分,www.phpfensi.com由于phpcms水印可以在后台管理设置,phpcms自带的水印方法通过读取配置文件获取路径,和读取数据库设置获取参数设置,那么这些地方需要手动进行设置。
对了,在upFile方法还要添加一段函数:
- if ($this->watermark) {
- $this->watermark($this->filePath,$this->filePath);
- }
然后打开UEditor百度编辑器php目录下的action_upload.php文件,加上是否添加水印的参数:
- /* 上传配置 */
- $base64 = "upload";
- switch (htmlspecialchars($_GET['action'])) {
- case 'uploadimage':
- $config = array(
- "pathFormat" => $CONFIG['imagePathFormat'],
- "maxSize" => $CONFIG['imageMaxSize'],
- "allowFiles" => $CONFIG['imageAllowFiles']
- );
- $fieldName = $CONFIG['imageFieldName'];
- $watermark = true;
- break;
然后在后面还有一句要改成:
- /* 生成上传实例对象并完成上传 */
- $up = new Uploader($fieldName, $config, $base64, $watermark);
这样就大功告成了,本文主要是提供思路和参考.
