附件 Hashcalc 校驗碼計算

☆效果如附件☆

開 ./templates/default/viewthread_attachlist.htm
找到

[Copy to clipboard] [ - ]

CODE:

{$attach[description]}

下一行增加

[Copy to clipboard] [ - ]

CODE:

MD5:

當然，還可以加上 SHA1及CRC32

[Copy to clipboard] [ - ]

CODE:

SHA1 : 
CRC32:

=======================================================
將上述代碼用

[Copy to clipboard] [ - ]

CODE:

及

[Copy to clipboard] [ - ]

CODE:

包起來，就成了只有發帖者及版面管理人員方能觀看該運算資訊，能稍微減少伺服器運算，不過這樣就變成上傳者利用此方法判斷是否上傳失敗而已
=======================================================
↓修改利用 attach 語法提至上層之附件亦會計算 Hashcalc 校驗碼~
Open ./include/discuzcode.func.php
Find

[Copy to clipboard] [ - ]

CODE:

($attach['description'] ? $attach['description'].' ' : '').

After Line,Add

[Copy to clipboard] [ - ]

CODE:

md5_file($attach['url']."/".$attach['attachment']).' '.

(當然，在這邊同樣可以加 SAH1 及 CRC32)
★此套件在附件檔越大越多時運算越多，速度就越慢~~★

QUOTE:

想說很多功能都有人作了，就來作個『與眾不同』的ＸＤ
可以讓你上傳檔案後用本機的 WinMD5 判斷是否在上傳過程中 Lose ，下載時也可以這樣判斷，雖然 WinRAR 本身就有用 CRC 作驗證了(所以說與眾不同不如說沒人會去作XD~)
其實要節省伺服器運算也是可以，在上傳時就將這些資訊寫入資料庫，這樣下次只要讀資料庫的值就行，不用重覆幫那個驗算
而且還可以讓他作運算判斷實際檔案跟資料庫紀錄的是否有不同，驗證是否有被人變更過~XD~不過這就變麻煩了，嘖~

資料庫版本在 #3

將 hashcalc 編碼加至資料庫，讓頁面載入速度不會因為這個東西降了下來
================================================
升級資料庫

CODE:

ALTER TABLE `cdb_attachments` ADD `md5` VARCHAR( 32 ) NOT NULL ;
ALTER TABLE `cdb_attachments` ADD `sha1` VARCHAR( 40 ) NOT NULL ;
ALTER TABLE `cdb_attachments` ADD `crc32` VARCHAR( 8 ) NOT NULL ;

CODE:

$attach['price'] = $maxprice ? (intval($attachprice[$key]) <= $maxprice ? intval($attachprice[$key]) : $maxprice) : 0;

CODE:

//Hashcalc Code
