How to intercept the title length of DEDECMS article?

Friends who know about dedecms must also be very familiar with how to get the tags of the previous and next articles. Dedecms gets the tags of the previous and next articles as: {dede:prenext get='pre'/} and {dede:prenext get='next'}, respectively.

In this tag, there is no function of setting the number of words in the title of the previous article or the next article, so how can we achieve this function? In fact, the dedecms system has also done a very good job, and it is also very thoughtful, which can be set up.

Dedecms sets the number of words in the title of the previous article and the next article:

Step 1: find the "include/arc.archives.class.php" file under dedecms and open it with DW or notepad.

Step 2: find $this- > PreNext ['pre'] = "previous post: {$preRow [' title']}"; add $preRow ['title'] = cn_substr ($preRow [' title'], 30) to this line; 30 means 30 bytes, or 15 Chinese characters. This can be set according to the actual situation.

Step 3: find $this- > PreNext ['next'] = "next article: {$nextRow [' title']}"; add $nextRow ['title'] = cn_substr ($nextRow [' title'], 30); to this line.

Then save it, and at this point, dedecms's method of setting the number of words in the title of the previous and next article is complete.
