uploadify上传预览+缩略图+水印实例
首先感谢各位大神网友的分享，我只是改改代码，让其更符合自己的业务逻辑
图片上传+缩略图+水印处理代码： //文件上传<br>
Public function _upload( $thumb = false , $thumbWidth = '' , $thumbHeight = '') {<br>
$upload = new \Think\Upload();// 实例化上传类<br>
$upload->maxSize = 3145728 ;// 设置附件上传大小<br>
$upload->exts = array('jpg', 'gif', 'png', 'jpeg');// 设置附件上传类型<br>
$upload->savePath = '/' . CONTROLLER_NAME .'/'; // 设置附件上传目录<br>
$info = $upload->upload();<br>
if(!$info) {<br>
return array('status' =>0, 'info'=> $upload->getError() );<br>
}else{<br>
if( $thumb ) { //生成缩略图<br>
<br>
$image = new \Think\Image(); <br>
<br>
foreach($info as $file) {<br>
$thumb_file = './Uploads/' . $file['savepath'] . $file['savename'];<br>
$save_path = './Uploads/' .$file['savepath'] . 'mini_' . $file['savename'];<br>
$image->open( $thumb_file )->text('德兴房产','./data/1.otf',30,'#A7AAA4',\Think\Image::IMAGE_WATER_SOUTHWEST)->save( $thumb_file );<br>
$image->open( $thumb_file )->text('德兴房产','./data/1.otf',24,'#A7AAA4',\Think\Image::IMAGE_WATER_SOUTHWEST)->thumb( $thumbWidth, $thumbHeight )->save( $save_path );<br>
return array(<br>
'status' => 1, <br>
'savepath' => $file['savepath'],<br>
'savename' => $file['savename'],<br>
'pic_path' => $file['savepath'] . $file['savename'],<br>
'mini_pic' => $file['savepath'] . 'mini_' .$file['savename']<br>
); <br>
}<br>
}else{<br>
foreach($info as $file) {<br>
return array(<br>
'status' => 1, <br>
'savepath' => $file['savepath'],<br>
'savename' => $file['savename'],<br>
'pic_path' => $file['savepath'].$file['savename']<br>
); <br>
}<br>
}<br>
}<br>
