How to replace the DedeCMS keyword? A perfect solution to the problem of DedeCMS keyword replacement

Problem description

There is an error in the keyword replacement of dream-weaving content: if you have two keywords, such as "CIT" (www.cit.cn/tags/cit.html) and "CIT Information Network" (www.cit.cn), but when the article is replaced, we find that there will be a problem, and the link becomes:

CIT information network

Solution

This kind of nesting error is not good for SEO or user experience. Here we have a solution, that is, replace the shorter one first, and then match the longer one, so that the system will first replace the keyword CIT instead of the CIT information network.

Modify the code

In fact, it is very simple to modify the code, we go directly to the include/arc.archives.class.php file, in 1226 lines of code, that is:

/ / for highlighting only, the maximum number of function _ highlight ($string, $words, $result, $pre) {global $cfg_replace_num; $string = str_replace ('', $string) may not be reached after multiple replacements.

Add a piece of code later so that it becomes

/ / for highlighting purposes, the maximum number of function _ highlight ($string, $words, $result, $pre) {global $cfg_replace_num; $string = str_replace ('",'', $string); uasort ($words,create_function ('$a, $baked recovery return strlen ($a) > strlen ($b);')

Summary

DedeCMS is indeed a sharp weapon for SEO enthusiasts, and how to use it well still needs to be pondered deeply.
