Some time you would like to increase the max upload file size in WordPress back-end but no access to php.ini file.  This is not the end of the world.  Actually,  you can still increase the upload file size by editing .htaccess file.  Just need to add the below code to your .htaccess which is located in the root folder of your WordPress install.

[code]php_value upload_max_filesize 8M[/code]

Note: Change 8 to your desired upload limit amount.

For the WordPress theme developers sometime we need to know the current page’s or post’s parent ID.  For example to list down the child pages list of the current page and this listing will show differently on the different pages. So we need to know the page’s or post’s parent ID. There is only a couple lines of code to get the parent ID.

[code]global $post;
$parent_ID = $post->post_parent;[/code]

That’s it!
