"weiwei/" . $_FILES["file"]["name"]; } echo "上传成功"; } } ?> <!doctype html> <html lang="en"> <head> <meta charset="UTF-8"> <title>注册表单</title> </head> <body> <form action="" method="post" enctype="multipart/form-data"> 姓名:<input type="text" name="name" value=""> <span class="error">* <?php echo $nameErr;?></span> 文件类型:<input type="file" name="file" id="file"> <img src="<?php echo "weiwei/".$_FILES['file']['name']?>" alt=""> <input type="submit" name="sub" value="提交"> </form> </body> </html>
