// Set up the objects needed
$my_wp_query = new WP_Query();
$all_wp_pages = $my_wp_query->query(array('post_type' => 'page'));

// Get the page as an Object
$portfolio =  get_page_by_title('Portfolio');

// Filter through all pages and find Portfolio's children
$portfolio_children = get_page_children( $portfolio->ID, $all_wp_pages );

// echo what we get back from WP to the browser
echo '
' . print_r( $portfolio_children, true ) . '
';

Solution

From the code below you can see the solution is fairly straight forward with the use of  ’query_posts‘.
We simply get the ID of the current page, run a query of the desired post type, and set the criteria to return posts which have the current page as the parent. Simple.

$curID = get_the_ID();

query_posts(
	array(
		'post_type'=>'page',
		'post_parent'=>$curID,
		'orderby' => 'menu_order',
		'order' => 'ASC'
	)
);

echo '<ul>';
	while ( have_posts() ) : the_post();
		echo '<li><a href="'.get_permalink().'">'.get_the_title().'</a></li>';
	endwhile;
echo '</ul>';

wp_reset_query();

What happens when you want to query certain posts which belong specifically to two different taxonomies?..A tax_query of course!

$currentID = $post->ID;
$myquery['tax_query'] = array(
   'relation' => 'AND',
   'posts_per_page'=>2,
   'post__not_in' => array($currentID),
   'post_type'=>'post',
    array(
      'taxonomy' => 'country',
      'terms' => array('united-kingdom'),
      'field' => 'slug',
    ),
    array(
      'taxonomy' => 'speciality',
      'terms' => array('driving'),
      'field' => 'slug',
    )
);
query_posts($myquery);

Easy, the query above will;

• Exclude the current post your viewing from the list.
• Return 2 posts which match the set criteria;
  • Posts set as ‘United Kingdom‘ in the ‘Country‘ taxonomy.
  • Posts set as ‘Driving‘ in the ‘Speciality‘ taxonomy.

There is plenty more you can do with the above queries – Be sure to check back soon for more hints and tips.

Most websites seem to feature a ‘Team’ page, which displays the users and their information, social network links, quotes, company position etc. I’m all for making a website as user friendly as possible, so the little amount of HTML in the WYSIWYG (What You See Is What You Get) the better. But I’ll come back to that later, for now… I’ll cover the basics.

So, in this tutorial I’ll be showing you how to create and display custom profile fields and how to display them on your WordPress website.

Adding Custom User Fields

Add the code below to your functions.php file.

add_action( 'show_user_profile', 'my_show_extra_profile_fields' );
add_action( 'edit_user_profile', 'my_show_extra_profile_fields' );

function my_show_extra_profile_fields( $user ) { ?>

	<h3>Extra profile information</h3>

	<table class="form-table">

		<tr>
			<th><label for="twitter">Twitter</label></th>

			<td>
				<input type="text" name="twitter" id="twitter" value="<?php echo esc_attr( get_the_author_meta( 'twitter', $user->ID ) ); ?>" class="regular-text" /><br />
				<span class="description">Please enter your Twitter username - e.g. DesignNodeUK</span>
			</td>
		</tr>

	</table>
<?php }

The above snippet of code will add a custom field to the user profile page, which will display at the bottom of the page.

<tr>
	<th><label for="twitter">Twitter</label></th>

	<td>
		<input type="text" name="twitter" id="twitter" value="<?php echo esc_attr( get_the_author_meta( 'twitter', $user->ID ) ); ?>" class="regular-text" /><br />
		<span class="description">Please enter your Twitter username.</span>
	</td>
</tr>

The above section of code is the custom part, feel free to change this to your liking. This can be duplicated as many times as you require, please note to change references to ‘twitter’ accordingly to the name of your additional fields.

Saving Custom User Fields

Now you have created your custom fields which are displayed on the ‘edit user’ page, you now need to be able to save them to the database. Please copy the code below into your functions.php file.

add_action( 'personal_options_update', 'my_save_extra_profile_fields' );
add_action( 'edit_user_profile_update', 'my_save_extra_profile_fields' );

function my_save_extra_profile_fields( $user_id ) {

	if ( !current_user_can( 'edit_user', $user_id ) )
		return false;

	update_usermeta( $user_id, 'twitter', $_POST['twitter'] );
}

Once you have added the code above to your functions.php file you’ll be able to save your custom fields. Please remember to duplicate line 9 and rename ‘twitter’ accordingly to the additional fields that you have created.

Display Custom Field On A Post

Now you have your fields and information saved in the database, all you need is the ability to display them on the front end of your website. Simple, just copy and paste the below code in your preferred section of loop-single.php and your information will be displayed accordingly. Please note, to display different fields you’d need to change ‘twitter’ accordingly.

<?php
$twitter = get_the_author_meta( 'twitter');
echo '<p>Follow me on twitter <a href="http://www.twitter.com/'.$twitter.'" target="_blank" title="Follow '.$twitter.' on Twitter">@'. $twitter. '</a></p>';
?>

Now you have the ability to display custom profile fields, don’t just stop at social media links… Explore and experiment, if you have any problems please let me know via the comments below.

So I brought a bike, mistakenly a mountain bike, but never the less… On went the road tyres and I was off. Now, it’s been 3 years since I last rode a bike and 5 years since my last charity bike ride (Round The Harours) so it goes without saying my cycling stamina wasn’t amazing. Currently my training consists of a 7.6mile ride twice a day (to and from work), fairly hilly so getting some decent training in there.

Within a month of buying my bike my I’ve reduced by 7.6mile journey time by 10 minutes, a nice achievement. Although 7.6 miles is a nice distance to sprint on a bike, it’s a bit of a mole hill compared to 60 miles from London to Brighton.

With all that aside I also set an optimistic goal of raising £400, so far I’ve raised £300, so I’m not too far off of the goal.

Well some people certainly like to show off. Have a gander through these!
