My WordPress website currently uses this custom permalink structure: %author%/%year%/%monthnum%/%day%/%postname%
In this case, %monthnum% instantiates numbered dates with a leading zero -- e.g., "09" for September. So, a sample URL might look like this:
mywebsite/username/2012/09/12/post-name
Is there a function I can add or .htaccess change that I can make which will remove the leading zeros from my permalink stucture? So, using the example above, my URLs would ideally look like this:
mywebsite/username/2012/9/12/post-name
Thank you! I've read up on WordPress' structure tags documentation (), but I can't find any solutions or plugins for the above-mentioned problem.

Reset to default 8 +50How about using custom rewrite tags/structure?
So we'll be using these two rewrite/structure tags:
%monthnum2%does the same thing as the%monthnum%tag, but without a leading zero; e.g.3and not03for March.%day2%does the same thing as the%day%tag, but without a leading zero; e.g.7and not07.
The steps:
In the theme functions file (
functions.php), add:add_action( 'init', function(){ add_rewrite_tag( '%monthnum2%', '([0-9]{1,2})', 'monthnum=' ); add_rewrite_tag( '%day2%', '([0-9]{1,2})', 'day=' ); } );That will generate the
%monthnum2%and%day2%(rewrite) tags and be used when WordPress (re-)generates the rewrite rules.And then add this:
add_filter( 'post_link', function( $permalink, $post ){ if ( preg_match( '/%(?:monthnum2|day2)%/', $permalink ) ) { $time = strtotime( $post->post_date ); $date = explode( ' ', date( 'n j', $time ) ); $permalink = str_replace( [ '%monthnum2%', '%day2%', ], [ $date[0], $date[1], ], $permalink ); $permalink = user_trailingslashit( $permalink, 'single' ); } return $permalink; }, 10, 2 );That will replace the rewrite tags in the permalink.
Go to the permalink settings page and then in the "Custom Structure" box, enter this structure:
/%year%/%monthnum2%/%day2%/%postname%/or/%author%/%year%/%monthnum2%/%day2%/%postname%, whichever applies.The point is, use
%monthnum2%to display the month number without a leading zero and%day2%to display the day number without a leading zero.Save your changes — both the theme functions file and the permalink settings — and go to the "Posts" page (
wp-admin/edit.php) and just check everything (mouse-over the post permalink and visit the post).
Filter 'month_link' and 'day_link', WordPress will find the matching posts then without further work.
Sample code:
add_filter( 'month_link', 't5_strip_leading_zeros_in_url' );
add_filter( 'day_link', 't5_strip_leading_zeros_in_url' );
function t5_strip_leading_zeros_in_url( $url )
{
// no pretty permalinks
if ( ! $GLOBALS['wp_rewrite']->get_month_permastruct() )
{
return $url;
}
return str_replace( '/0', '/', $url );
}
htaccess solution
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} ^/.*?/.*?/[0][1-9]/.*?/.*?$
RewriteRule ^(.*?)/(.*?)/[0]([1-9])/ /$1/$2/$3/ [R=301]
</IfModule>
I created a working example for you to test here
What this does is check for the path structure provided if the third path contains, a leading 0 and number 1-9, eg /03/, then applies the rewrite rule to the third-path, leaving the first two paths and additional paths intact (.*?)/(.*?)/. The rule only changes the third path if that path matches (01-09) [0]([1-9]) from eg /03/ to /3/.
Does not affect /uploads/ month images path because the uploads structure does not match the structure provided. Please test using above link to see if it suits your needs.
