Dede Summary length, Dedecms summary limit, dedecms summary words

If you can effectively control the word count of the article summary, then you can make the page layout very flexible.

In Dedecms, the main ways to invoke the article summary on a list page are:

1:[field:info/]
2:[field:description/]
3:[field:info function= "Cn_substr (@me, number of characters)"/]
4:[field:description function= "Cn_substr (@me, number of characters)"/]

Method One:
The first step
Into the database Find the field under Table dede_archives description Point change, field type Select BLOB (some say change to text, but I did not try it)
Step Two
In the Dede directory article_eidt.php name $description = Cn_substr ($description, 250); Here the 250 is not 250 words, but 250 characters, so is not used to 250 this, You can add more than 0 after 250. I tried to do it.
Step Three
In the background, the system---system basic parameters---Other settings---the length of the automatic summary (for example, written as: 250000) (in fact, this place can not be, Dede has been the default is 0-250, here after one or two steps of the change has not worked, any of the lines, "0" except)
Apply, do not set too big, avoid increasing database redundancy
---------------------------
Method Two:
In archives_add.php:$description = CN_SUBSTRR ($description, $cfg _auot_description); archives_edit.php: $description = CN_SUBSTRR ($description, +);
These two statements are used to define the digest,$cfg _auot_description is the variable of the automatic summary length, and 250 is the maximum of the length
But why do you have to specify a length for the abstract?
So this method simply removes the abstract length and changes the code to:
archives_add.php $description = $description;
archives_edit.php $description = $description;
