本文讲述了thinkphp3.2实现上传图片的控制器方法。分享给大家供大家参考，具体如下：

public function file()

{

$baseUrl = str_replace('\\', '/', dirname($_SERVER['SCRIPT_NAME']));

import('ORG.Net.UploadFile');

import('ORG.Util.Services_JSON');

$upload = new UploadFile();

$upload->maxSize = 3145728;

$upload->allowExts = array('jpg', 'gif', 'png', 'jpeg');

$upload->savePath = './uploads/Images/';

$info = $upload->uploadOne($_FILES['imgFile']);

$file_url = $baseUrl . 'uploads/Images/' . $info['0']['savename'];

if ($info) {

header('Content-type: text/html; charset=UTF-8');

$json = new Services_JSON();

echo $json->encode(array('error' => 0, 'url' => $file_url));

exit;

} else {

$this->error($upload->getErrorMsg());

}

}

public function file_manager()

{

import('ORG.Util.Services_JSON');

$php_path = dirname(__FILE__) . '/';

$php_url = dirname($_SERVER['PHP_SELF']) . '/';

$root_path = $php_path . './uploads/Images/';

$root_url = $php_url . './uploads/Images/';

$ext_arr = array('gif', 'jpg', 'jpeg', 'png', 'bmp');

$dir_name = emptyempty($_GET['dir']) ? '' : trim($_GET['dir']);

if (!in_array($dir_name, array('', 'image', 'flash', 'media', 'file'))) {

echo "Invalid Directory name.";

exit;

}

if ($dir_name !== '') {

$root_path .= $dir_name . "/";

$root_url .= $dir_name . "/";

if (!file_exists($root_path)) {

mkdir($root_path);

}

}

//根据path参数，设置各路径和URL

if (emptyempty($_GET['path'])) {

$current_path = realpath($root_path) . '/';

$current_url = $root_url;

$current_dir_path = '';

$moveup_dir_path = '';

} else {

$current_path = realpath($root_path) . '/' . $_GET['path'];

$current_url = $root_url . $_GET['path'];

$current_dir_path = $_GET['path'];

$moveup_dir_path = preg_replace('/(.*?)[^\/]+\/$/', '$1', $current_dir_path);

}

echo realpath($root_path);

//排序形式，name or size or type

$order = emptyempty($_GET['order']) ? 'name' : strtolower($_GET['order']);

//不允许使用..移动到上一级目录

if (preg_match('/\.\./', $current_path)) {

echo 'Access is not allowed.';

exit;

}

//最后一个字符不是/

if (!preg_match('/\/$/', $current_path)) {

echo 'Parameter is not valid.';

exit;

}

//目录不存在或不是目录

if (!file_exists($current_path) || !is_dir($current_path)) {

echo 'Directory does not exist.';

exit;

}

//遍历目录取得文件信息

$file_list = array();

if ($handle = opendir($current_path)) {

$i = 0;

while (false !== ($filename = readdir($handle))) {

if ($filename{0} == '.') continue;

$file = $current_path . $filename;

if (is_dir($file)) {

$file_list[$i]['is_dir'] = true; //是否文件夹

$file_list[$i]['has_file'] = (count(scandir($file)) > 2); //文件夹是否包含文件

$file_list[$i]['filesize'] = 0; //文件大小

$file_list[$i]['is_photo'] = false; //是否图片

$file_list[$i]['filetype'] = ''; //文件类别，用扩展名判断

} else {

$file_list[$i]['is_dir'] = false;

$file_list[$i]['has_file'] = false;

$file_list[$i]['filesize'] = filesize($file);

$file_list[$i]['dir_path'] = '';

$file_ext = strtolower(pathinfo($file, PATHINFO_EXTENSION));

$file_list[$i]['is_photo'] = in_array($file_ext, $ext_arr);

$file_list[$i]['filetype'] = $file_ext;

}

$file_list[$i]['filename'] = $filename; //文件名，包含扩展名

$file_list[$i]['datetime'] = date('Y-m-d H:i:s', filemtime($file)); //文件最后修改时间

$i++;

}

closedir($handle);

}

//排序

usort($file_list, 'cmp_func');

$result = array();

//相对于根目录的上一级目录

$result['moveup_dir_path'] = $moveup_dir_path;

//相对于根目录的当前目录

$result['current_dir_path'] = $current_dir_path;

//当前目录的URL

$result['current_url'] = $current_url;

//文件数

$result['total_count'] = count($file_list);

//文件列表数组

$result['file_list'] = $file_list;

//输出JSON字符串

header('Content-type: application/json; charset=UTF-8');

$json = new Services_JSON();

echo $json->encode($result);

}

希望本文所述对大家基于ThinkPHP框架的PHP程序设计有所帮助。
