The length of the default dedecms article title is 60 characters, but now the 20 Chinese characters of the article title are far from enough to meet the needs, so what we have to do is to modify the default word limit of the system. The method is as follows:
1. Modify the "system - > basic system parameters - > other options - > Article Title length" of Zhimeng background to the desired length, for example, 200 (maximum value cannot exceed 255), click OK to save
2. Execute SQL statement in "system - > SQL command line tool" in Zhimeng background:
alter table dede_archives change title title varchar(250)
Note: dede? Is the prefix of the default installation database. If you want to modify it when you install dedecms, you need to modify it now.
