补充代码,两个问号处应该填写: if ( is_uploaded_file ( $_FILES [ $myfile ][ 'tmp_name' ])){ $tpname = $_FILES [ $myfile ][ 'name' ]; $type = $_FILES [ $myfile ][ 'type' ]; $tmp = $_FILES [ $myfile ][ 'tmp_name' ]; $error = $_FILES [ $myfile ][ 'error' ]; $photo = "upimages/" . $tpname ; switch ( $type ){ case "image/pjpeg" : $pdz = 1 ; break ; case "image/jpeg" : $pdz = 1 ; break ; case "image/gif" : $pdz = 1 ; break ; case "image/png" : $pdz = 1 ; break ; default : echo " 不能上传其它格式文件! " ; } if ( $pdz ==___?__ && ____?____ == 0 ){ move_uploaded_file ( $tmp , $photo ); }
