How does dedecms delete articles as well as attachments?

The modification method of deleting articles and attachments by dedecms

Dedecms delete articles also delete attachments to modify the method, the use of dedecms friends can refer to.

First add two functions

The code is as follows:

/ * get the body part of the document according to the document id * / function getArcBody ($arcid) {global $dsql; if (empty ($arcid)) return; $body =''; $query = "select arc.*,ch.addtable,ch.fieldset from `dede_ arctiny` as arc left join `dede_ channeltype` as ch on arc.channel=ch.id where arc.id=$arcid"; $row = $dsql- > GetOne ($query); if (empty ($row) return; $addtable = $row ['addtable']; $fieldset = $row [' fieldset'] Include_once (DEDEINC.'./dedetag.class.php'); $dtp = new DedeTagParse (); $dtp- > SetNameSpace ('field',''); $dtp- > LoadSource ($fieldset); if ($dtp- > CTags) {foreach ($dtp- > CTags as $tid= > $tag) {if ($tag- > GetAtt (' type') = = 'htmltext') {$body = $tag- > GetName (); break;} if (! empty ($body)) {$query = "select $body from `$addtable` where aid=$arcid"; $row = $row > dsql- ($dsql-) $body = $row [$body]; return $body;} return;} / * parse the local picture of the document content * / function get_img_from_body ($body) {$result = array (); if (empty ($body)) return $result; preg_match_all ('/\ ssrc= ([\ "|\']) ([^\ 1] *?)\. (gif | jpg | jpeg | png)\ 1 syntax. If (! empty ($res [2])) {foreach ($res [2] as $k = > $v) {$result [] = $v.'.'.$res [3] [$k];}} return $result;}

Post this code after include/common.func.php

Then open the background (assuming the default dede is used as the background) dede/inc/inc_batchup.php file

Add the code on line 22 as follows:

$body = getArcBody ($aid)

Then on line 139, that is,

Return true

Add the following code to the top line

The code is as follows:

If ($body) {$img_arr = get_img_from_body ($body); if (! empty ($img_arr)) {foreach ($img_arr as $v) {$img_file = GetTruePath (). Str_replace ($GLOBALS ['cfg_basehost'],'', $v); if (file_exists ($img_file) & &! is_dir ($img_file) @ unlink ($img_file);}

This makes it possible to delete local images with fields of type "htmltext" when you delete a document.
