< p > WordPress offers you the ability to create a custom URI structure for your permalinks and archives . The following & #8220;tags” are available:</p>
< ul >
2004-01-12 00:55:14 +00:00
< li >< code >% year %</ code > --- The year of the post , 4 digits , for example < code > 2004 </ code > </ li >
2004-01-14 06:47:52 +00:00
< li >< code >% monthnum %</ code > --- Month of the year , for example < code > 05 </ code ></ li >
2004-01-12 00:55:14 +00:00
< li >< code >% day % </ code >--- Day of the month , for example < code > 28 </ code ></ li >
< li >< code >% postname %</ code > --- A sanitized version of the title of the post . So & quot ; This Is A Great Post !& quot ; becomes & quot ; < code > this - is - a - great - post </ code >& quot ; in the URI </ li >
< li >< code >% post_id %</ code > --- The unique ID # of the post, for example <code>423</code> <strong></strong></li>
2003-10-26 05:25:26 +00:00
</ ul >
2003-12-04 22:53:15 +00:00
< p > So for example a value like < code >/ archives /% year %/% monthnum %/% day %/% postname %/</ code > could give you a permalink like < code >/ archives / 2003 / 05 / 23 / my - cheese - sandwich /</ code > . For this to work you ' ll need mod_rewrite installed on your server for the rule generation rule to work below . In the future there may be other options . </ p >
