对于wordpress的链接优化除了伪静态之外另一个广为流传的是wordpress去掉分类链接中自带的category目录;虽然是老生常谈了,但是在这里讲一下也不为过;网上有各种去除category目录的的免费插件,WP No category Base 插件就不错。但是插件毕竟不安全,
大挖推荐大家一个不用插件来实现WordPress去掉分类链接中category的方法,将下面代码添加到你当前主题的 functions.php 文件中的<?内即可:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 |
