What should I do if the DEDE backend updates ads but the frontend has no changes?

Many friends have modified the advertising code in the background, but the advertisements in the front desk have not changed. This reason is a caching problem.

Solution suitable for novices:

If you modify the advertising code, Then we find the management on the right. There are 3 options under the management, [JS] [Change] [Delete], these 3. At this time we only need to click JS. Here is a preview of the JS ad, and then we will return Go to the front desk and take a look. Have the ads changed automatically?

Comprehensive solution:

In addition, when previewing every time, we need to make the following modifications to the advertising module. The following are posted by friends on the forum You can refer to the following methods to solve it.

After installing the advertising module that comes with DedeCms, I found that after modifying the advertising information, the advertisement called by the front desk still had the previous modified information. I checked the source code and found that the cache was called, but the ad_edit of DedeCMS. After php edited and saved the information, the original cache was not deleted. The modification is as follows:

Open the file dede/ad_edit.php and find the following code:

$dsql->ExecuteNoneQuery($query);
ShowMsg("成功更改一则广告代码！",$ENV_GOBACK_URL);

Modify to the following code:

$dsql->ExecuteNoneQuery($query);
// 删除广告缓存文件 begin
// dedecms V57_GBK 2011-08-12
if(file_exists(DEDEDATA."/cache/myad-$aid.htm")){
@unlink(DEDEDATA."/cache/myad-$aid.htm");
}
// 删除广告缓存文件 end
ShowMsg("成功更改一则广告代码！",$ENV_GOBACK_URL);
