[1]php实例：文件上传及错误代码

来源: 互联网发布时间: 2013-12-24

1，html表单部分

代码示例:

<html>
<head>
<title>php文件上传-www.</title>
</head>
<body>
<h3>文件上传</h3>
选择上传文件:<br>
<form action="/blog_article/uploader.html" method="post" enctype="multipart/form-data">
<input type="file" name="file" size="45">
<br>
<input type="submit" value="上传文件">
</form>
</body>
</html>

2，文件上传程序 uploader.php

代码示例:

<?php
/**
* 接收文件上传信息
* by www.
*/

if( $_FILES['file']['name'] != "" )
{
    copy ( $_FILES['file']['tmp_name'],
     "C:/Apache/htdocs/" . $_FILES['file']['name'] )
    or die( "Could not copy file" );
}
else
{
    die( "No file specified" );
}
?>
<html>
<head>
<title>上传成功</title>
</head>
<body>
<h3>文件上传成功...</h3>
<ul>
<li>文件名称: <?php echo $_FILES['file']['name']; ?></li>
<li>文件大小: <?php echo $_FILES['file']['size']; ?> bytes</li>
<li>文件类型: <?php echo $_FILES['file']['type']; ?></li>
</ul>
<a href="/blog_article/</php echo $_FILES[.html'file']['name']; ?>">点这里查看文件</a>
</body>
</html>

[2]php实例：文件上传脚本

php文件上传代码分享，如下所示：

<html>
 <head>
 <title>文件上传脚本-www.</title>
 </head>
 <body>
 <div>
 <?php
 if ( isset( $_FILES['fupload'] ) ) {
     print "文件名称: ".     $_FILES['fupload']['name']       ."<br />";
     print "文件大小: ".     $_FILES['fupload']['size'] ." bytes<br />";
     print "临时文件名称: ".$_FILES['fupload']['tmp_name']   ."<br />";
     print "文件类型: ".     $_FILES['fupload']['type']       ."<br />";
     print "错误消息: ".    $_FILES['fupload']['error']      ."<br />";

     if ( $_FILES['fupload']['type'] == "image/gif" ) {

         $source = $_FILES['fupload']['tmp_name'];
         $target = "upload/".$_FILES['fupload']['name'];
         move_uploaded_file( $source, $target );// or die ("Couldn't copy");
         $size = getImageSize( $target );

         $imgstr = "<p><img width=\"$size[0]\" height=\"$size[1]\" ";
         $imgstr .= "src=/index.html"$target\" alt=\"uploaded image\" /></p>";

         print $imgstr;
     }
 }
 ?>
 </div>
 <form enctype="multipart/form-data"
     action="/blog_article/</php print $_SERVER[.html'PHP_SELF']?>" method="post">
 <p>
 <input type="hidden" name="MAX_FILE_SIZE" value="102400" />
 <input type="file" name="fupload" /><br/>
 <input type="submit" value="上传文件" />
 </p>
 </form>
 </body>
 </html>

附：简单的文件上传表单

<html>
<head>
<title>简单的文件上传表单</title>
</head>
<body>
<form enctype="multipart/form-data"
   action="/blog_article/</print $_SERVER[.html'PHP_SELF']?>" method="post">
<p>
<input type="hidden" name="MAX_FILE_SIZE" value="102400" />
<input type="file" name="fupload" /><br/>
<input type="submit" value="上传文件" />
</p>
</form>
</body>
</html>

以上这个是最基础的文件上传表单，其中设置了最大上传文件的大小，通过$_SERVER['PHP_SELF']获得当前php文件名。

[3]php实例：验证复选框

来源: 互联网发布时间: 2013-12-24

验证复选框的php代码，如下：

<?php
/**
* 在php中验证复选框的有效性
* by www.
*/
$value = 'yes';
echo "<input type='checkbox' name='subscribe' value='yes'/> 验证数据";

if (isset($_POST['subscribe'])) {
    if ($_POST['subscribe'] == $value) {
        $subscribed = true;
    } else {
        $subscribed = false;
        print '提交的复选框值无效。';
    }
} else {
    $subscribed = false;
}

if ($subscribed) {
    print '验证有效！';
} else {
    print '验证无效！';
}
