This modification allows blog authors to assign a minimum user level required to view each post. The default value is zero (retroactively applied to all existing posts), which means anyone can see the post. By choosing the post level on the admin post or edit screen, the author can limit who sees what.
Extract the contents of the file post_level.tgz into your WordPress directory. No files will be overwritten. The contents of the download file are thus:
This modification requires the addition of a new row to the wp_posts table, called “post_level”. There are sever al ways to accomplish this:
1) Make sure the included post_level_install.php is in your wp-admin directory. Call this page from your browser:
2) Edit the included post_level.mysql file to correctly identify the name of your wp_posts table (only necessary if you’re using a custom table prefix for your database tables), then execute the following:
mysql -uusername -p wordpress < post_level.mysql
Replace”username” with your database username, as defined in wp-config.php.
Replace “wordpress” with the name of your WordPress database, as defined in wp-config.php
3) Use a tool like phpMyAdmin to manually alter the table. The post_level row must be UNSIGNED INT(2), default zero, not null.
Next, you need to modify five files:
Again, there are several ways to do this:
1) From the command line, run the patch command in your WordPress directory to automatically modify all the files for you using the included post_level.diff file:
patch -p0 < post_level.diff
2) If you haven’t modified any of the listed files yourself (to apply other modifications, for example), you can simply copy the files from the modified/ directory to their respective locations:
cp -r ./* ..
3) You can look through either the post_level.diff file, or the files in the modified/ directory to see what changes I’ve made. I’ve prefaced all of my modifications with this line:
// SDM 23-05-2004 post_level modification
to help you identify what has been changed.
USING THE MODIFICATION
Once installed, you’ll note that the post and edit screens now have a drop-down select box labelled “Post level”. This is the minimum user level required to view the post.
