Php上传文件方法
前台页面：
<form action="../control/filecontrol.php" method="post" enctype="multipart/form-data">
<table border="1" width="100%">
<tr>
<td>选择图片</td>
<td><input type="file" name="file_file"/></td>
</tr>
<tr>
<td>图片名称</td>
<td><input type="text" name="down_name"/></td>
</tr>
<tr>
<td colspan="2"><input type="submit" value="保存文件" /></td>
</tr>
</table>
</form>
上传操作页面：
if(isset ( $_FILES ["file_file"] )){
$file = @$_FILES['file_file'];
//上传验证
if ($file["error"] > 0) {
echo "上传错误！";
exit;
}
//对文件大小对比1000KB以下的图片可以上传
$fileSize = sprintf("%.2f",($file["size"] / 1024 / 1024)); //M
if($fileSize > 100){
echo "文件太大超过100M不能上传!";
exit;
}
//文件名称
$down_name = $file['name'];
$down_urlname = StackConst::get_date_str().substr($down_name,strrpos($down_name,"."),strlen($down_name));
//从缓存区移动文件
if(move_uploaded_file($file["tmp_name"],StackConst::res_file_url().$down_urlname)){
//装填信息
$arrFileInfo = array(
"down_name"=>@$_POST['down_name'],
"down_urlname"=>$down_urlname,
"down_savedate"=>StackConst::get_date()
);
//引入FileDao
require_once '../dao/FileDao.php';
//实例化FileDao
$fileDao = new FileDao();
if($fileDao->addFileSource($arrFileInfo)){
echo "文件上传成功！";
StackConst::jump_page("../view/filelist.php");
}else{
echo "文件上传失败！";
}
}else{
echo "文件上传失败！";
}
}
其中这里包括了把上传文件的信息写入数据库
FileDao.php
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<?php
header ( 'Content-type: text/html; charset=utf-8' );
ini_set("error_reporting","E_ALL & ~E_NOTICE");

public function getFileList(){

还有个是：【获取各种类型的时间串，上传里面用到了】
