这是一款简单PHP图片上传类带图片显示代码,应该可以说是上传文件最简单的上传类了,可以设置要显示图片高度与宽度,文件大小等.
uploadimg.class.php文件,代码如下:
-
class upload
-
{
-
var $upload_name;
-
var $upload_tmp_address;
-
var $upload_server_name;
-
var $upload_filetype ;
-
var $file_type;
-
var $file_server_address;
-
var $image_w=900;
-
var $image_h=350;
-
var $upload_file_size;
-
var $upload_must_size= 50000;
-
function upload_file()
-
{
-
$this->upload_name = $_files["file"]["name"];
-
$this->upload_filetype = $_files["file"]["type"];
-
$this->upload_server_name = date("y_m_dh_i_s").$this->upload_name;
-
$this->upload_tmp_address = $_files["file"]["tmp_name"];
-
$this->file_type = array("image/gif","image/pjpeg");
-
$this->upload_file_size = $_files["file"]["size"];
-
if(in_array($this->upload_filetype,$this->file_type))
-
{ if($this->upload_file_size < $this->upload_must_size)
-
{
-
echo("上传成功,谢谢支持");
-
$this->file_server_address = "d:www.111cn.netupload/".$this->upload_server_name;
-
move_uploaded_file($this->upload_tmp_address,$this->file_server_address);
-
echo("<img src=$this->file_server_address width=$this->image_w height=$this->image_h/>");
-
-
-
}
-
else
-
{
-
echo("文件容量太大");
-
}
-
}
-
else
-
{
-
echo("不支持此文件类型,请重新选择");
-
-
}
-
-
}
-
-
}
html上传代码,代码如下:
-
<form id="form1" name="upload" enctype="multipart/form-data" method="post" action="upload.php">
-
<input type="hidden" name="max_file_size " />
-
<input type="file" name="file" />
-
<input type="submit" name="submit" value="提交" />
-
</form>
调用方法,upload.php,代码如下:
-
inlcude('uploadimg.class.php');
-
$dd = new upload;
-
$dd->upload_file();
-
