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();
