Rename Post format string in WordPress theme


Because post format string is hard coded in post.php, so you can’t change them in filter way. To rename the post format string and display in a theme, you can add the following function in function.php.

function post_format_nicename() {
		global $post;
		$slug = str_replace('post-format-', '', get_post_format($post->ID));
		if(empty($slug)) {
				$slug = 'standard';
		$source = array('Standard', 'Status');
		$replacement = array(__('Blog Post', 'textdomain'),__('Status Update','textdomain'));
		$strings = str_replace($source, $replacement, get_post_format_strings());
        $string = $strings[$slug];
		return $string;

To display the mod-ed post formant name, call this function

echo post_format_nicename();

How to filter “Standard” Post format in WordPress

Post format

As you know Post Formats is a theme feature introduced with Version 3.1. A Post Format is a piece of meta information that can be used by a theme to customize its presentation of a post. The Post Formats feature provides a standardized list of formats that are available to all themes that support the feature. There are new template tag to play with post_format as below

WordPress Codex

However, when you try to implement post_format, usually you’ll try to sort out the posts for each formats. For example, show all images format.

<a href="<?php echo get_post_format_link('image');?>">
Show Image Posts

The above code do present a link taking you to post_fomart archives page, pretty easy right? So… how about display the standand post? Unfortunately, there is no out of box function to do that. Let’s work it out.


Setup theme support in functions.php, I put the post formats in vars, because we need to reused them in some place within the theme. Additionally, I created another function to register query variable to handle new query for standard post format.

/* Register Query Variables*/
add_filter('query_vars', 'my_queryvars' );
function my_queryvars( $qvars )
$qvars[] = 'filter';
return $qvars;
/* Post formats support */
$my_post_formats = array( 'status','aside','image', 'gallery', 'link', 'video', 'audio' );
foreach ($my_post_formats as $shortname) {
	$my_post_formats_longname[] = 'post-format-'.$shortname;
add_theme_support( 'post-formats', $my_post_formats );

The filter links

<a href="<?php echo add_query_arg( 'filter','standard',remove_query_arg('post_format'));?>"><?php echo get_post_format_string('');?></a>
<?php global $my_post_formats; foreach ($my_post_formats as $postformat) { ?>
	| <a href="<?php echo get_post_format_link($postformat);?>"><?php echo get_post_format_string(str_replace('post-format-', '', $postformat) ); ?></a>
<?php } ?>

the loop

Put the following code before the loop. This is a new taxonomy query since WordPress 3.0, it allows you to setup own query by taxonomy terms. And you may notice that I’ve put “NOT IN” operator to filter out standard posts. It is because “standard” post do not have post-format- taxonomy. The first condition to determine the from the $_GET request.

<?php if(get_query_var('filter') == "standard") { 	global $my_post_formats_longname; 	$args = array( 			'tax_query' =--> array(
			array( 'taxonomy' => 'post_format',
				  'field' => 'slug',
				  'terms' => $my_post_formats_longname,
				  'operator' => 'NOT IN'
	query_posts( $args );

That’s it

Btw, I hope there have a better solution in future WordPress release. Thanks for reading!

Data Protector: Object is a mounted filesystem => not restored.

Unexpected mounted filesystems detected when restoring a disk imageWhen restoring a disk image, you get a message that the disk image being restoredis a mounted filesystem and will not be restored:

Object is a mounted filesystem => not restored.

This happens when an application on the disk image leaves some patterns on thedisk image. The patterns confuse the system call that verifies whether the filesystemon the disk image is mounted or not, so the system call reports that there is a mountedfilesystem on the disk image.


1. Try zero out the device

dd if=/dev/zero of=/dev/r[logical volume] bs=8k

2. For AIX, lslv [logical volume] , verify it doesn’t contain DS_LVZ, otherwise, recreate it without -T O
3. For AIX with IBM SAN Volume Controller, run

lquerypr -ph  /dev/vpathX

4. For AIX, try not varyon the volume group in concurrent mode.

Submitting WordPress post from frontend without a plugin

This tutorial will guide you to create your own custom post composing form to enable fast blogging with your favorite theme without adding a plugin. I’m looking for any alternative to not porting P2, however…. none.,  finally that’s the reason i wrote it, and It was also inspired by the original development from


I found the code from , but it doesn’t  handle file attachment, indeed most people and I was demand on image uploads for status update,  photo blogging.. whatever . But to get working with build-in WordPress media upload function require a lots of code work,  and if you prefer a fully functional media library, you could base on P2 theme instead.

How it work

  1. It create a post form to allow  the post content inserted by wp_insert_post.
  2. following the post_id, it attach the uploaded files to the post.
  3. Set the first ordered image to the post “featured images”
  4. Lastly, you call get_all_thumbnails before the_content() in order to retrieve the uploaded files.


The critical limitation is lack of media features, unlike build-in media library, you can customize your post images and place it on your desired position. Therefore the images only able to retrieve by the_post_thumbnail() for single image or get_all_thumbnails() for multiple images.

Getting ORA-01180 error during database restoration


Having restore database from rman but got a ORA-01180 error, it happen often because your backup file source directory is different then original backup path.

Let’s try

Restore pfile and recreate all necessary directory eg: archive log, admin, a/b/c/udump, datafile… every directory you specified in the pfile

Copy your backup pfile to %ORACLE_HOME%\dbs\

sqlplus / as sysdba
sqlplus> startup nomount pfile='%ORACLE_HOME%\dbs\initORAINST.ora'

Restore controlfile

rman target /
RMAN> restore controlfile from 'D:\path\to\controlfile.bak'

Restore database

RMAN> alter database mount;
RMAN> restore database;

Then you got a similar message as below, because originally your backup path is somewhere different then your current backup file source path.

creating datafile fno=1 name=D:\ORADATA\ORAINST\SYSTEM01.DBF
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at 02/18/2011 16:55:06
ORA-01180: can not create datafile 1
ORA-01110: data file 1: 'D:\ORADATA\ORAINST\SYSTEM01.DBF'

Try this to re-catalog your backup files then re-run the restore

rman> catalog start with 'D:\backup\source'
