其实上传文件明白了道理也就很简单啦,小编当时学的时候也是一头雾水,搞了好多天才弄懂一点,好了废话少说吧,嘿嘿。首先运用的是tp3.2的框架,我这里前端名字是img.html
所以后台首先运用的是public function img(),然后选择上传的商品种类,再根据种类来选择固定的函数,而upload也就是确定所上传文件的格式还有保存路径等。最后再根据db_img上传到数据库。
首先是前端代码
<!DOCTYPE html> <html> <head> <title>后台管理</title> <link rel="stylesheet" type="text/css" href="__PUBLIC__/css/img.css"/> </head> <body> <header> <h1><img src="__PUBLIC__/image/admin_logo.png"/></h1> <ul class="rt_nav"> <li><a href="{:U(‘Login/img‘)}" target="_blank" class="website_icon">站点首页</a></li> <li><a href="{:U(‘Login/order2‘)}" class="admin_icon">查看交易</a></li> <li><a href="{:U(‘Login/loginprocess‘)}" class="quit_icon">安全退出</a></li> </ul> </header> <aside class="lt_aside_nav content mCustomScrollbar"> <h2><a href="index.php">起始页</a></h2> <ul> <li> <dl> <dt>商品信息</dt> <!--当前链接则添加class:active--> <dd><a href="{:U(‘Login/img‘)}" >商品列表</a></dd> <dd><a href="{:U(‘Login/img‘)}" >商品分类</a></dd> <dd><a href="{:U(‘Login/img‘)}" >商品列表</a></dd> <dd><a href="{:U(‘Login/img‘)}" >商品信息</a></dd> </dl> </li> <li> <dl> <dt>订单信息</dt> <dd><a href="{:U(‘Login/order2‘)}">订单列表</a></dd> <dd><a href="{:U(‘Login/order3‘)}">用户购物车列表</a></dd> </dl> </li> <li> <p class="btm_infor">? 八号当铺 版权所有</p> </li> </ul> </aside> <h2><strong style="color:grey;text-align: center;" >欢迎<span style="color:red">{$_SESSION[‘username‘]}</span>成为卖家</strong></h2> <section> <h2><strong style="color:grey;">卖家上传</strong></h2> <form method="POST" enctype="multipart/form-data"> <ul class="ulColumn2"> <li> <span class="item_name" style="width:120px;">商品名称:</span> <input type="text" class="textbox textbox_295" placeholder="文本信息提示..." name="f_name"/> <!-- <span class="errorTips">错误提示信息...</span> --> </li> <li> <span class="item_name" style="width:120px;">商品价格:</span> <input type="text" class="textbox textbox_295" placeholder="文本信息提示..." name="money" /> <!-- <span class="errorTips">错误提示信息...</span> --> </li> <li> <span class="item_name" style="width:120px;">种类:</span> <select class="select" name="sel"> <option value="close">服装</option> <option value="book">书刊</option> <option value="dian">电子</option> </select> <!-- <span class="errorTips">错误提示信息...</span> --> </li> <!-- <li> <span class="item_name" style="width:120px;">是否热销:</span> <label class="single_selection" ><input type="radio" value="y" />推荐</label> <label class="single_selection"><input type="radio" value="n" />不推荐</label> </li> --> <li> <span class="item_name" style="width:120px;">摘要:</span> <textarea placeholder="摘要信息" class="textarea" style="width:500px;height:100px;" name="message"></textarea> </li> <li> <span class="item_name" style="width:120px;">上传图片:</span> <label class="uploadImg"> <input type="file" name="file[]" /> <span>上传图片</span> </label> </li> <li> <span class="item_name" style="width:120px;"></span> <input type="submit" value="提交" class="link_btn"/> </li> </ul> </form> </section> </body> </html>
其次是后台(运用的是tp3.2框架)
// //后台添加图片
public function upload() { // //实例化上传类 $upload = new \Think\Upload(); $upload->maxSize = 3145728; $upload->exts = [‘jpg‘, ‘jpeg‘, ‘gif‘, ‘png‘]; $upload->savePath = ‘./Public/Uploads/‘; $upload->rootPath = ‘./‘; $info = $upload->upload(); $upload = new Upload(); if (!$info) { $this->error($upload->getError()); // $this->error(‘shuangchuanshibai ‘,U(‘Login/loginss‘),2); } else { //$this->success(‘上传成功‘); return $info; } } public function insert() { $login = D(‘logins‘); $result = $login->where([‘username‘ => $_SESSIN[‘username‘]])->field()->find(); // if(empty($_FILES)){ if (empty($_FILES)) { $this->error(‘请选择需要上传的文件‘); } if (!empty($_FILES)) { $arr = $this->upload(); foreach ($arr as $key => $value) { $path[][‘savepath‘] = $value[‘savepath‘] . $value[‘savename‘]; } // $data[‘single‘]=‘推荐‘; $data[‘f_name‘] = $_POST[‘f_name‘]; // $data[‘create_time‘]=time(); $data[‘money‘] = $_POST[‘money‘]; $data[‘message‘] = $_POST[‘message‘]; $data[‘username‘] = $_SESSION[‘username‘]; // $data[‘create_time‘] = time // $data[‘login_id‘] = $result[‘id‘];(); if (isset($data)) { //如果上传文件的信息不为空,我们就将这些信息保存到数据库中 $this->db_img($data, $path); } else { $this->error(‘数据为空‘); } } } public function db_img($data, $path) { // if($_POST[‘sel‘]==‘close‘){ // if($_POST[‘single‘]==‘y‘){ $file = D(‘file‘); $img = D(‘file_c‘); foreach ($path as $vo) { $data[‘savepath‘] = $vo[‘savepath‘]; } // $data[‘single‘] ="推荐"; $data[‘f_name‘] = $_POST[‘f_name‘]; $data[‘username‘] = $_SESSION[‘username‘]; $t = time(); $data[‘create_time‘] = date("Y-m-d H:i:s", $t); $data[‘money‘] = $_POST[‘money‘]; $data[‘message‘] = $_POST[‘message‘]; // $img->add(); if (!$img->create($data) || !$file->create($data)) { $this->error(‘上传失败‘); } else { if (!$img->add($data) || !$file->add($data)) { $this->error(‘上传失败‘); } } $this->success(‘上传成功....‘, U(‘Login/img‘)); } //insert1 public function insert1() { $login = D(‘logins‘); $result = $login->where([‘username‘ => $_SESSIN[‘username‘]])->field()->find(); // if(empty($_FILES)){ if (empty($_FILES)) { $this->error(‘请选择需要上传的文件‘); } if (!empty($_FILES)) { $arr = $this->upload(); foreach ($arr as $key => $value) { $path[][‘savepath‘] = $value[‘savepath‘] . $value[‘savename‘]; } $data[‘f_name‘] = $_POST[‘f_name‘]; $data[‘money‘] = $_POST[‘money‘]; $data[‘message‘] = $_POST[‘message‘]; $data[‘username‘] = $_SESSION[‘username‘]; if (isset($data)) { //如果上传文件的信息不为空,我们就将这些信息保存到数据库中 $this->db_img1($data, $path); } else { $this->error(‘数据为空‘); } } } public function db_img1($data, $path) { // if($_POST[‘sel‘]==‘close‘){ // if($_POST[‘single‘]==‘y‘){ $img = D(‘file_b‘); $file = D(‘file‘); foreach ($path as $vo) { $data[‘savepath‘] = $vo[‘savepath‘]; } $data[‘f_name‘] = $_POST[‘f_name‘]; $data[‘username‘] = $_SESSION[‘username‘]; $t = time(); $data[‘create_time‘] = date("Y-m-d H:i:s", $t); $data[‘money‘] = $_POST[‘money‘]; $data[‘message‘] = $_POST[‘message‘]; // $img->add($data); if (!$img->create($data) || !$file->create($data)) { $this->error(‘上传失败‘); } else { if (!$img->add($data) || !$file->add($data)) { $this->error(‘上传失败‘); } } $this->success(‘上传成功....‘, U(‘Login/img‘)); } //insert2 public function insert2() { $login = D(‘logins‘); $result = $login->where([‘username‘ => $_SESSIN[‘username‘]])->field()->find(); // if(empty($_FILES)){ if (empty($_FILES)) { $this->error(‘请选择需要上传的文件‘); } if (!empty($_FILES)) { $arr = $this->upload(); foreach ($arr as $key => $value) { $path[][‘savepath‘] = $value[‘savepath‘] . $value[‘savename‘]; } $data[‘f_name‘] = $_POST[‘f_name‘]; $data[‘money‘] = $_POST[‘money‘]; $data[‘message‘] = $_POST[‘message‘]; $data[‘username‘] = $_SESSION[‘username‘]; if (isset($data)) { //如果上传文件的信息不为空,我们就将这些信息保存到数据库中 $this->db_img2($data, $path); } else { $this->error(‘数据为空‘); } } } public function db_img2($data, $path) { // if($_POST[‘sel‘]==‘close‘){ // if($_POST[‘single‘]==‘y‘){ $img = D(‘file_d‘); $file = D(‘file‘); foreach ($path as $vo) { $data[‘savepath‘] = $vo[‘savepath‘]; } $data[‘f_name‘] = $_POST[‘f_name‘]; $data[‘username‘] = $_SESSION[‘username‘]; $t = time(); $data[‘create_time‘] = date("Y-m-d H:i:s", $t); $data[‘money‘] = $_POST[‘money‘]; $data[‘message‘] = $_POST[‘message‘]; // $img->add($data); if (!$img->create($data) || !$file->create($data)) { $this->error(‘上传失败‘); } else { if (!$img->add($data) || !$file->add($data)) { $this->error(‘上传失败‘); } } $this->success(‘上传成功....‘, U(‘Login/img‘)); } public function img() { if (IS_POST) { if ($_POST[‘sel‘] == ‘close‘) { $this->insert(); } if ($_POST[‘sel‘] == ‘book‘) { $this->insert1(); } if ($_POST[‘sel‘] == ‘dian‘) { $this->insert2(); } } $this->display(); }
