Sample6_1.php 中创建Form:
//显示上传状态和图片
<div id="showimg"></div>
//上传文件需要定义enctype,为了显示图片将target设为uploadframe
<form id="uploadform" action="/blog_article/process_upload.html" method="post"
enctype="multipart/form-data" target="uploadframe">
Upload a File:<br />
<input type="file" id="myfile" name="myfile" />
//上传文件
<input type="submit" value="Submit" onclick="uploadimg(document.getElementById('uploadform')); return false;" />
<iframe id="uploadframe" name="uploadframe" src="/blog_article/process_upload.html" ></iframe>
</form>
上传图片函数 uploadimg:
function uploadimg(theform){
//提交Form
theform.submit();
//在showimg <div>中显示上传状态
setStatus ("Loading...","showimg");
}
//上传状态函数
function setStatus (theStatus, theObj){
obj = document.getElementById(theObj);
if (obj){
obj.innerHTML = "<div bold\">" + theStatus + "</div>";
}
}
process_upload.php 提供文件上传功能:
<?php
//提供图片类型校验
$allowedtypes = array("image/jpeg","image/pjpeg","image/png", "image/x-png","image/gif");
//文件存放目录
$savefolder = "images";
//如果有文件上传就开始干活
if (isset ($_FILES['myfile'])){
//检查上传文件是否符合$allowedtypes类型
if (in_array($_FILES['myfile']['type'],$allowedtypes)){
if ($_FILES['myfile']['error'] == 0){
$thefile = "$savefolder/".$_FILES['myfile']['name'];
//通过move_uploaded_file上传文件
if (!move_uploaded_file($_FILES['myfile']['tmp_name'], $thefile)){
echo "There was an error uploading the file.";
}
else{
?>

上面代码最后部分的doneloading 函数就是用来显示图片及修改图片尺寸大小。其中会用到thumb.php,它会在images目录中生成出源图片的大、中、小三个尺寸,有兴趣可以研究一下。欢迎大家拍砖~
文中源码打包下载
1.先到网上下载phpmyadmin,再解压到可以访问的web目录下(如果是虚拟空间,可以解压后通过ftp等上传到web目录下),当然您可以修改解压后该文件的名称。
2.配置config文件
打开libraries下的config.default.php文件,依次找到下面各项,按照说明配置即可:
A.访问网址
引用:
$cfg['PmaAbsoluteUri'] = '';这里填写phpmyadmin的访问网址
B.mysql主机信息
引用:
$cfg['Servers'][$i]['host'] = 'localhost'; // MySQL hostname or IP address
填写localhost或mysql所在服务器的ip地址,如果mysql和该phpmyadmin在同一服务器,则按默认localhost
$cfg['Servers'][$i]['port'] = ''; // MySQL port - leave blank for default port
mysql端口,如果是默认3306,保留为空即可
C.mysql用户名和密码
引用:
$cfg['Servers'][$i]['user'] = 'root'; // MySQL user 访问phpmyadmin使用的mysql用户名
fg['Servers'][$i]['password'] = ''; // MySQL password (only needed对应上述mysql用户名的密码
D.认证方法
引用:
$cfg['Servers'][$i]['auth_type'] = 'cookie';
在此有四种模式可供选择,cookie,http,HTTP,config
config方式即输入phpmyadmin的访问网址即可直接进入,无需输入用户名和密码,是不安全的,不推荐使用。
当该项设置为cookie,http或HTTP时,登录phpmyadmin需要数据用户名和密码进行验证,,具体如下:
PHP安装模式为Apache,可以使用http和cookie;
PHP安装模式为CGI,可以使用cookie
E.短语密码(blowfish_secret)的设置
引用:
$cfg['blowfish_secret'] = '';
如果认证方法设置为cookie,就需要设置短语密码,置于设置为什么密码,由您自己决定 ,但是不能留空,否则会在登录phpmyadmin时提示错误
好了,到此为止,您已经成功安装了phpmyadmin,简单吧 ,赶快登录体验下吧
说明:
该文档说明的只是安装phpmyadmin的基本配置,关于config.default.php文件中各个配置参数的详细说明可以
phpMyAdmin 就是一种 MySQL 数据库的管理工具,安装该工具后,即可以通过 web 形式直接管理 MySQL 数据,而不需要通过执行系统命令来管理,非常适合对数据库操作命令不熟悉的数据库管理者,下面详细说明该工具的安装方法。
一、下载
1、先到官方站点下载phpMyAdmin 安装包:http://www.phpmyadmin.net/ (安装包含各种语言all-languages)
2、再解压到 web 可以访问的目录下,如果是虚拟空间,可以解压后通过 ftp 工具上传到 web 目录下,同时您可以修改解压后该文件的名称(你可以自定义目录名称)。
二、配置
3、打开 /libraries/config.default.php文件(旧版本是根目录下的config.inc.php文件),用写字板(不要用记事本,这是UTF8编码)进行编辑,按照说明配置即可。
4、查找 $cfg['PmaAbsoluteUri']=‘'; // 修改为你将上传到空间的phpMyAdmin的网址
如:$cfg['PmaAbsoluteUri'] =‘http: // 网站域名/phpmyadmin/';
5、查找 $cfg['Servers'][$i]['host'] =‘localhost'; // 通常用默认,也有例外,可以不用修改
6、查找 $cfg['Servers'][$i]['auth_type'] =‘config'; // 在自己的机子里调试用config;如果在网络上的空间用cookie.
在此有四种模式可供选择:cookie,http,HTTP,config
① config 方式即输入phpMyAdmin 的访问网址即可直接进入,无需输入用户名和密码,是不安全的,不推荐使用。
② 设置cookie,http,HTTP方式,登录 phpMyAdmin 需要数据用户名和密码进行验证。
具体如下:PHP 安装模式为 Apache,可以使用 http 和 cookie;PHP 安装模式为 CGI,可以使用 cookie。
7、查找 $cfg['Servers'][$i]['user'] = ‘root'; // MySQL用户名
8、查找 $cfg['Servers'][$i]['password'] =''; // MySQL 密码 (only needed 留空就可以了)
9、查找 $cfg['Servers'][$i]['only_db'] = ''; // 你只有一个数据就设置一下,设置为你的数据库名;如果你想架设服务器,那么建议留空
10、查找 $cfg['DefaultLang'] = ‘zh'; // 这里是选择语言,zh代表简体中文的意思
11、查找$cfg['blowfish_secret'] =''; // 如果认证方法设置为cookie,就需要设置短语密码,设置为什么密码,由您自己决定,这里不能留空,否则会在登录 phpMyAdmin 时提示如下图所示的错误。
12、设置完毕后保存,现在可以上传到网络空间上了,浏览http://网站域名/phpmyadmin/测试一下。(输入数据库的用户名及密码就可以了)
如果要安装过程中出现:“phpMyAdmin - 错误 缺少 mysqli 扩展。请检查 PHP 配置。”错误。
解决方法如下:
①到phpmyadmin文件夹的\libraries\config.default.php文件中找:$cfg['Servers'][$i]['extension']='mysql';语句。
②如果有找到$cfg['Servers'][$i]['extension']='mysql';这句,就继续查找下面这句$cfg['Servers'][$i]['extension']='mysqli'; 并把其的注释去掉。
③如果没有找到$cfg['Servers'][$i]['extension']='mysql';这句,就把$cfg['Servers'][$i]['extension']='mysqli';语句,改成$cfg['Servers'][$i]['extension']='mysql'; 语句。(即确保 " mysql " 值能生效)
