这篇文章主要为大家详细介绍了thinkphp上传图片功能，和jquery预览图片效果,具有一定的参考价值，感兴趣的小伙伴们可以参考一下
先上效果图：
html和js代码如下:
<!DOCTYPE html> <html lang="zh-cn"> <head> <meta charset="utf-8"> <title></title> </head> <body> <!-- 表单提交 --> <form action="{:url('Index/uploadImg')}" enctype="multipart/form-data" method="post"> <div class="form-group has-success has-feedback"> <label for="info_photo" class="col-sm-2 control-label">物品图片</label> <div class="col-sm-10"> <span class="btn btn-success btn-file"> 选择图片 <span class="glyphicon glyphicon-picture" aria-hidden="true"></span> <input type="file" name="image" value="" id="info_photo" onchange='PreviewImage(this)' /> </span> </div> </div> <div class="form-group has-success has-feedback"> <label for="info_desc" class="col-sm-2 control-label"><span style="color: red;">* </span> 详细描述</label> <div class="col-sm-10"> <textarea class="form-control" rows="5" id="info_desc" name="info_desc" placeholder="如需补充，请填写..." title="可包含中文数字和常用字符"></textarea> <div id="photo_info" class="photo_info"></div> </div> <button type="submit">提交</button> </form> </div> </body> <!-- js实现图片预览效果 --> <script type="text/javascript"> //上传图片立即预览 function PreviewImage(imgFile) { var filextension = imgFile.value.substring(imgFile.value .lastIndexOf("."), imgFile.value.length); filextension = filextension.toLowerCase(); if ((filextension != '.jpg') && (filextension != '.gif') && (filextension != '.jpeg') && (filextension != '.png') && (filextension != '.bmp')) { alert("对不起，系统仅支持标准格式的照片，请您调整格式后重新上传，谢谢 !"); imgFile.focus(); } else { var path; if (document.all)//IE { imgFile.select(); path = document.selection.createRange().text; document.getElementById("photo_info").innerHTML = ""; document.getElementById("photo_info").style.filter = "progid:DXImageTransform.Microsoft.AlphaImageLoader(enabled='true',sizingMethod='scale',src="" + path + "")";//使用滤镜效果 } else//FF { path = window.URL.createObjectURL(imgFile.files[0]);// FF 7.0以上 //path = imgFile.files[0].getAsDataURL();// FF 3.0 document.getElementById("photo_info").innerHTML = "<img id='img1' width='120px' height='100px' src='"+path+"'/>"; //document.getElementById("img1").src = path; } } } </script> </html>
php代码如下:
<?php namespace appindexcontroller; use thinkController; use thinkView; use thinkRequest; class Index extends Controller { public function index() { $view = new View(); return $view->fetch(); } public function uploadImg(Request $request) { if (request()->isPost()) { //获取详细描述信息 $param = $request->post(); // 获取表单上传文件 例如上传了001.jpg $file = request()->file('image'); // 移动到框架应用根目录/public/uploads/ 目录下 if($file){ $info = $file->move(ROOT_PATH . 'public' . DS . 'uploads'); if ($info) { $data = ROOT_PATH .DS . 'public/uploads' . DS . $info->getSaveName(); echo $data;//输出路径如：C:phpStudyWWW p_test\public/uploads20180727eb7fa19f0035bf2bdd5e6a3690091d93.jpg }else{ // 上传失败获取错误信息 echo $file->getError(); } } //接下来进行入库操作 } else { $view = new View(); return $view->fetch(); } } }
