It can be used for both posts and pages so I may use both post or page interchangeable throughout this post. I’ve recently used the new ‘Post Thumbnail’ feature in 2.9 to link child pages from a ‘Parent’ page using the Post Thumbnail as an image link.

Wordpress Post Thumbnail

The code below is an example of how to use the ‘get_the_post_thumbnail()’ to list the current page children with its content and a title.

<?php
// get pages
$pages = get_pages("child_of=".$post->ID.'&sort_column=post_title&sort_order=desc&parent='.$post->ID);
// loop through pages pages to get page properties
foreach($pages as $page) {
?>
<div class="wp-caption alignleft">
// create an hyperlink from the get_page_link method and embed the image retrieved from get_the_post_thumbnail in it
<a href="<?php echo get_page_link($page->ID) ?><?php echo get_the_post_thumbnail($page->ID); ?>
// get the title and use it as the caption
<?= $page->post_title ?>
</div>
// get the content
<?php echo $page->post_content; ?>
<?php edit_post_link('Edit.', '', '', $page->ID); ?>
<?php } ?>

Hi Baby, today the 19th of December not only marks the day that you get one year older, it also marks the day you become one year more beautiful. I created this section on my website just to remind you that although I am busy all the time there is space in my busy technological lifestyle for you. Today also marked another wonderful day that we will spend together in a lifetime where I have been blessed with you.

A poem from me to you

Money Poor, Love Rich

Diamonds I can’t afford to buy
For your birthday which is coming by
As you know I’m just an ordinary guy
With money being in short supply
But I have affections that pile high
And love that reaches all the way to the sky
With you my love and affections will lie
No matter how the years fly.

I really love you (but I guess you already realised that after nearly 9 years now ) and wish you all the best and hope you enjoy the rest of the day.

Do the following to remove it in emacs.

; goto top of buffer
M-x replace-string C-q C-m RET

The control-q will allow you to type control characters into the
input buffer.

Additionally, you could use the dos2unix command.

Apache was expecting the owner of the folders in the document root to be www-data, I figured this is for some form of security purposes.

How I got rid of the problem

I got rid of the problem by changing the group and owner of my WordPress install folder in apache root to www-data by executing the following command:

cd /yourwordpress_dir/

sudo chown -R www-data:www-data *

The other day I was locked out of my Ubuntu after upgrading from Intrepid to Jaunty and GDM decided to take a break. The real problem occurred when I urgently needed my CV to be sent off that day and the most up-to-date CV was on my Ubuntu login, sigh.

What I did

After launching the recovery mode from GRUB I was able to get to a root console. This was good because my girlfriend had her laptop so I could send the CV from her Windows XP system (don’t laugh).

Anyway, here goes… but remember before accessing root you should consider backing up your important files so any mishap wont have you eating your heart out.

Please be careful when running commands under Linux as root, if you are unsure then ask someone before making any changes as root.

Detecting USB hard drive

After you plug in your USB device to your USB port, linux add new device into /dev/ folder. At this stage you are not able to use this device. You need to mount it to your system first in order to be able retrieve any data. To find out what name your device have you can run fdisk command:

# fdisk -l

You will get output similar to this:

Disk /dev/sda: 60.0 GB, 60060155904 bytes 255 heads, 63 sectors/track, 7301 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes     Device Boot      Start         End      Blocks   Id  System /dev/sda1               1        7301    58645251   83  Linux

Creating the mount point

Create directory where you want to mount your device:

mkdir /mnt/sda1

Edit /etc/fstab

To automate this process you can edit /etc/fstab file and add line similar to this:

/dev/sda1       /mnt/sda           vfat    defaults        0       0

Run mount command to mount all not yet mounted devices. Keep in mind that if you have more different USB devices in you system, device name can vary!!!

# mount -a

On Ubuntu

Run the following command on your Ubuntu machine as root.

Please be careful when running commands under Linux as root, if you are unsure then ask someone before making any changes as root.

sudo smbpasswd -a 'yourusername'

Add a password when prompted (can be different from pc password).

On Windows

Simply access \\xxx.xxx.xxx.xxx\. Where xxx.xxx.xxx.xxx can either be the machines’ IP address or name.

When asked for credentials, provide user name, password for samba.

That’s it, you now have access to your Ubuntu system.

The Problem

When you migrate your cforms plugin from server to server, cform apparently keeps reference to the initial install which for me caused a lot of problem. For instance, when the website was loading I realise that a file was being referenced from my local server. huh!!! I was curious which plugin was doing this and went straight to the database only to find out that the culprit (with no fingers pointing) was cforms.

These are the references that it keeps:

$cformsSettings['global']['cforms_root']
$cformsSettings['global']['tinyURI']
$cformsSettings['global']['cforms_root_dir']
$cformsSettings['global']['cforms_upload_dir']

Because the cforms data is being saved in the database as serialised data changing these from the database would cause the data to be corrupted and in some instances cause your cforms install useless.

For me, I had both problems, I initially tried to update the data from the database and it got corrupted and I tried using the methods prescribed by cforms to fix this problem but that didn’t work. Cforms method is to disable and enable the plugin or edit the data in the little form that the corrupt data page gives you.

Remember, always backup your wordpress install, both database and files before messing around, especially in production environments.

Also, in cforms, go to global settings and backup all settings.

The Solution to Updating the References

After finding that the problem was with cforms I went into cforms code and found what they were doing and here is the final result. Use this method if you have moved over your installation and want to update the references to your production server.

/**
 * Updates cforms data to reflect the current host that it is on
 *
 * @return
 */
function update_cforms_data() {
	if($cformsSettings['global']['cforms_root'] != WP_PLUGIN_URL . '/cforms') :
		$cformsSettings['global']['cforms_root'] = WP_PLUGIN_URL . '/cforms';
		update_option('cforms_settings',$cformsSettings);
	endif;

	if($cformsSettings['global']['tinyURI'] != get_option('siteurl') . '/wp-includes/js/tinymce') :
		$cformsSettings['global']['tinyURI'] = get_option('siteurl') . '/wp-includes/js/tinymce';
		update_option('cforms_settings',$cformsSettings);
	endif;

	if($cformsSettings['global']['cforms_root_dir'] != WP_PLUGIN_DIR . '/cforms') :
		$cformsSettings['global']['cforms_root_dir'] = WP_PLUGIN_DIR . '/cforms';
		update_option('cforms_settings',$cformsSettings);
	endif;

	if($cformsSettings['global']['cforms_upload_dir'] != WP_PLUGIN_DIR . '/cforms$#$') :
		$cformsSettings['global']['cforms_upload_dir'] = WP_PLUGIN_DIR . '/cforms$#$';
		update_option('cforms_settings',$cformsSettings);
	endif;
}

The Solution to Remove Cforms Totally and Reinstall

Use this method to totally remove cforms data from the database, especially if cforms constantly reports that its data is corrupt and doesn’t give you the option to remove it.

$wpdb->query("DELETE FROM `$wpdb->options` WHERE option_name LIKE 'cforms%'");
$wpdb->query("DROP TABLE IF EXISTS $wpdb->cformssubmissions");
$wpdb->query("DROP TABLE IF EXISTS $wpdb->cformsdata");

Remember to backup your website before messing around.

• WordPress version: WordPress 2.8.1
• Cforms version: Cforms 2 10.5.2
