Thinkphp3.2 Linux下缩略图生成失败
代码在本地运行正常,部署到Linux就不好使了。
前端代码:
<script type="text/javascript"> $(function() { $("#file_upload").uploadify({ height : 30, swf : '{$Think.const.SITE_URL}public/GoodsUploadify/uploadify.swf', uploader : '{:U("Goods/GoodsUploadify")}', width : 120, //允许上传的文件后缀 'fileTypeExts':'*.jpg;*.jpge;*.gif;*.png', 'multi' : false, //是否支持多文件上传 'simUploadLimit' : 1, //一次同步上传的文件数目 'sizeLimit' : 31457280, //设置单个文件大小限制 'queueSizeLimit' : 1, //队列中同时存在的文件个数限制 //'buttonImage':'/public/uploadify_shop/upbutton.jpg',//浏览按钮的背景图片路径 'formData': { 'sessionid': '<?php echo session_id();?>'}, 'onUploadSuccess' : function(file, data, response) { var data = $.parseJSON(data); $('#images').attr('src','{$Think.const.SITE_URL}public/GoodsImages/'+data['url']); $('#original_img').val(data['url']); }, }); }); </script>
php端代码:
public function GoodsUploadify() { if (! empty ( $_FILES )) { if (isset ( $_POST ['sessionid'] )) { session_id ( $_POST ['sessionid'] ); session_start (); // 注意此函数要在session_id之后 } import ( 'Org.Net.UploadFile' ); $upload = new \UploadFile (); $upload->maxSize = 3292200; $upload->allowExts = explode ( ',', 'jpg,gif,png,jpeg' ); $upload->savePath = "./public/GoodsImages/"; // 设置需要生成缩略图,仅对图像文件有效 $upload->thumb = true; // 设置需要生成缩略图的文件后缀 $upload->thumbPrefix = 'z_,s_'; // 生产2张缩略图 // 设置引用图片类库包路径 $upload->thumbMaxWidth = '520,225'; // 设置缩略图最大高度 $upload->thumbMaxHeight = '520,225'; // 设置上传文件规则 $upload->saveRule = 'uniqid'; // 删除原图 // $upload->thumbRemoveOrigin = true; $this->ajaxReturn ( 1, 'json' ); if (! $upload->upload ()) { // 上传错误提示错误信息 $this->ajaxReturn ( 2, 'json' ); $this->ajaxReturn ($upload->getErrorMsg (), 0, 'json' ); } else { // 上传成功 获取上传文件信息 $this->ajaxReturn ( 3, 'json' ); $info = $upload->getUploadFileInfo (); $temp_size = getimagesize ( "./public/GoodsImages/" . $info ['0'] ['savename'] ); if ($temp_size [0] < 100 || $temp_size [1] < 100) { // 判断宽和高是否符合要求 $this->ajaxReturn ( 0, '图片宽或高不得小于100px!', 0, 'json' ); } $data ['picName'] = $info ['0'] ['savename']; $data ['status'] = 1; $data ['url'] = $data ['picName']; $data ['info'] = $info; $this->ajaxReturn ( $data, 'json' ); } } }
其中$this->ajaxReturn ( (1/2/3), 'json' );为调试代码
可以返回1,当1注销时2和3都不返回,1,2,3都注销时,什么都不返回,
缩略图和原图都是一个路径,原图上成功说明缩略图路径没错。所以我就搞不懂了。
现在问题就是,缩略图生成失败,没有返回值,求大神帮忙,本来想把上传插件源码传上来参考的,没有上传附件功能啊,放这个框里 又太长 = =
回复讨论(解决方案)
if (isset ( $_POST ['sessionid'] )) {
session_id ( $_POST ['sessionid'] );
session_start (); // 注意此函数要在session_id之后
}
THINKPHP 自动启用 session_start ,你自己设置的,重复了。
import ( 'Org.Net.UploadFile' );
$upload = new \UploadFile ();
你在以上之前调试,echo "ddddddddddd";exit;
看看能否有输出信息。
还有,开启调试模式,有错误,会自动显示错误
本地正常,表示代码没有问题
Linux下不正常,可能是:
1、文件不全
2、路径和文件名没注意大小写
3、权限问题
4、php版本问题
if (isset ( $_POST ['sessionid'] )) {
session_id ( $_POST ['sessionid'] );
session_start (); // 注意此函数要在session_id之后
}

session_start 注销后,还是没返回值。 dddd能返回,
看我贴的代码:if (! $upload->upload ()) { // 上传错误提示错误信息 这行之前 输出都是可以返回的。

1、文件不全应该不会吧,
2、缩略图和原图上传公用一个路径,原图能上传,说明路径没错
3、php5.3.6的,TP3.2只要5.3以上就可以,不然早报错了
4、我已经把网站的跟目录递归777了,下面所有的都是777 都看过了上传的那个文件夹也是777 不然原图也传不上啊
清空 Runtime 目录再试,应该没有其他可能了
清空 Runtime 目录再试,应该没有其他可能了
我觉得另蹊跷,先清完缓存,再回
清空 Runtime 目录再试,应该没有其他可能了
没用呢,连个返回值都木有,哎。
既然原图成功,那应该是处理成缩略图的时候出错了。
你应该到具体生成缩略图的代码里调试,看看哪一步出错了。
缩略图如果生成失败,检查缩略图的文件路径和权限是否正确。
