大家好 在我的PHP的网站我有一个脚本上传图片,请参见下面文件允许PHP上传图像
$uploaddir = $root_path."images/uploaded_images/category/";
$small_file_name = trim($_FILES['cat_image1']['name']);
$small_file_len = strlen($small_file_name);
$small_file_ext = strtolower(substr($small_file_name,-4)); // select last 4 characters
$small_uploadfile = $uploaddir. $_FILES['cat_image1']['name'];
if($small_file_len>4 and ($small_file_ext==".gif" or $small_file_ext==".jpg" or $small_file_ext=="jpeg")){
if ($small_file_ext=="jpeg")
$uniqname = uniqid(rand()).".".$small_file_ext;
else
$uniqname = uniqid(rand()).$small_file_ext;
$thumb_filename1 = "thumb_".$uniqname; // store uniqname into database
$uploadfile = $uploaddir.$uniqname; //uncomment for local testing
if (move_uploaded_file($_FILES['cat_image1']['tmp_name'], $uploadfile)) {
chmod($uploadfile,0777);
list($width, $height, $type, $attr) = getimagesize($uploadfile);
$max_width = 276;
$max_height = 162;
$a = new Thumbnail($uploadfile,$max_width,$max_height,$uploaddir.$thumb_filename1,100,'');
$a->create();
}else{
$flag=1;
$frm_server_side_error= $frm_server_side_error."Error in uploading image,";
}
}
else{
$flag=2;
$frm_server_side_error= $frm_server_side_error."Image not in gif or jpg format,";
}
脚本上传到其无法看到服务器后(我显示拇指图像)。所以我通过FTP检查了该映像的文件权限并给予了读取权限。因此图像显示。但是我将读写权限授予了分类文件夹,并且它是父文件夹。上传后如何查看图像(默认读取权限,上传文件,即拇指图像。) 我注意到,实际图像具有读取权限,但拇指图像没有读取权限。我只需要显示拇指图像。请帮我
在此先感谢
服务器运行的是什么操作系统? – seanieb 2011-02-14 06:36:10
