最近在做php第二阶段的项目，需要用到头像上传的功能
我们要完成头像上传功能，一共要写两个php页面，第一个页面我们叫做touxiang.php，第二个页面我们叫做upload.php
1.touxiang.php
1 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
2 <html xmlns="http://www.w3.org/1999/xhtml">
3 <head>
4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
5 <title>无标题文档</title>
6
7 <link href="bootstrap-3.3.7-dist/css/bootstrap.min.css" rel="stylesheet" type="text/css" />
8 <script src="bootstrap-3.3.7-dist/js/jquery-1.11.2.min.js"></script>
9 <script src="bootstrap-3.3.7-dist/js/bootstrap.min.js"></script>
10
11 <style type="text/css">
12 #yl{ width:200px; height:200px; background-image:url(img/avatar.png); background-size:200px 200px;}
13 #file{ width:200px; height:200px; float:left; opacity:0;}
14 .modal-content{ width:500px;}
15 .kk{ margin-left:130px;}
16 </style>
17
18 </head>
19
20 <body>
21
22
23
24 <!-- 按钮触发模态框 -->
25 <button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
26 上传头像
27 </button>
28 <!-- 模态框（Modal） -->
29 <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
30 <div class="modal-dialog">
31 <div class="modal-content">
32 <div class="modal-header">
33 <button type="button" class="close" data-dismiss="modal" aria-hidden="true">
34 ×
35 </button>
36 <h4 class="modal-title" id="myModalLabel">
37 上传头像
38 </h4>
39 </div>
40 <div class="modal-body">
41 <form id="sc" action="upload.php" method="post" enctype="multipart/form-data" target="shangchuan">
42
43 <input type="hidden" name="tp" value="" id="tp" />
44
45 <div id="yl" class="kk">
46 <input type="file" name="file" id="file" onchange="document.getElementById(‘sc‘).submit()" />
47 </div>
48
49
50
51 </form>
52
53 <iframe style="display:none" name="shangchuan" id="shangchuan">
54 </iframe>
55
56 </div>
57 <div class="modal-footer">
58 <button type="button" class="btn btn-default" data-dismiss="modal">关闭
59 </button>
60 <!--<button type="button" class="btn btn-primary">
61 提交更改
62 </button>-->
63
64 </div>
65 </div><!-- /.modal-content -->
66 </div><!-- /.modal -->
67 </div>
68
69
70 </body>
71
72 <script type="text/javascript">
73
74 //回调函数,调用该方法传一个文件路径，该变背景图
75 function showimg(url)
76 {
77 var div = document.getElementById("yl");
78 div.style.backgroundImage = "url("+url+")";
79
80 document.getElementById("tp").value = url;
81 }
82
83 </script>
84
85 </html>
在这个页面我们需要引入一个模态框和bootstrap.min.css，jquery-1.11.2.min.js，bootstrap.min.js三个文件
2.upload.php
1 <?php
2
3 if($_FILES["file"]["error"])
4 {
5 echo $_FILES["file"]["error"];
6 }
7 else
8 {
9 if(($_FILES["file"]["type"]=="image/jpeg" || $_FILES["file"]["type"]=="image/png")&& $_FILES["file"]["size"]<1024000000)
10 {
11 $fname = "./img/".date("YmdHis").$_FILES["file"]["name"];
12
13 $filename = iconv("UTF-8","gb2312",$fname);
14
15 if(file_exists($filename))
16 {
17 echo "<script>alert(‘该文件已存在！‘);</script>";
18 }
19 else
20 {
21 move_uploaded_file($_FILES["file"]["tmp_name"],$filename);
22
23 unlink($_POST["tp"]);
24
25 echo "<script>parent.showimg(‘{$fname}‘);</script>";
26 }
27
28 }
29 }
网页显示效果如下：
好了，这样一个简单的头像上传就做好了，赶快试试吧！
