The Dede abbreviated title is 36 characters long, which is the default limit for the dream system.
The "abbreviated title" in Dedecms, by default, has a short title length of 36 characters, or 18 kanji. As a subtitle of the article, it may not be enough. At this point, we need to manually modify Dede's core file again:
Workaround:
1. Modify database field settings
Log in to the database with phpMyAdmin, locate the Dede_archives table, and then find the Shorttitle field, and change the value from 36 to 200.
The ps:36 is 36 characters, the equivalent of 18 Chinese characters, and this is changed to 200, or 100 kanji.
2. Modify the core file
Locate the Dede Management background directory (the default directory is/dede/) and locate the following files:
archives_add.php
archives_do.php
archives_edit.php
article_add.php
article_edit.php
The source code can be replaced in bulk by web editing software or Notepad.
$shorttitle = CN_SUBSTRR ($shorttitle, 36);
Change 36 to the length you need. If modified to 200. After completing the above two steps, the modification succeeds.
