How to: Manually define to show full post or excerpt on your homepage

Do you use excerpts or full posts on your blog excerpts? Personnally, I think they’re both good. The only problem is that you can’t, by default, use both excerpts and full posts on your blog homepage. Here’s a code to do it.

On your index.php file, replace your current loop by this one:

<?php if (have_posts()) :
    while (have_posts()) : the_post();
         $customField = get_post_custom_values("full");
         if (isset($customField[0])) {
              //Custom field is set, display a full post
         } else {
              // No custom field set, let's display an excerpt

Display the Digg Button only when the custom field is present

// check for digg button for single page
$digg = get_post_meta($post->ID, 'Digg', $single = true);
// if there's a single page digg button
if($digg !== '') { ?>
<script type="text/javascript">
(function() {
var s = document.createElement('SCRIPT'), s1 = document.getElementsByTagName('SCRIPT')[0];
s.type = 'text/javascript';
s.async = true;
s.src = 'http://widgets.digg.com/buttons.js';
s1.parentNode.insertBefore(s, s1);
<?php } // end if statement
// if there's not a digg button
else { echo ''; } ?>

<meta name="description" content="
<?php if ( (is_home()) || (is_front_page()) ) {
    echo ('Your main description goes here');
} elseif(is_category()) {
    echo category_description();
} elseif(is_tag()) {
    echo '-tag archive page for this blog' . single_tag_title();

    echo 'archive page for this blog' . the_time('F, Y');

How to: Link to some external ressource in post title

The first thing to do is to open your functions.php file and paste the following code:

function print_post_title() {
    global $post;
    $thePostID = $post->ID;
    $post_id = get_post($thePostID);
    $title = $post_id->post_title;
    $perm  = get_permalink($post_id);
    $post_keys = array(); $post_val  = array();
    $post_keys = get_post_custom_keys($thePostID);

    if (!empty($post_keys)) {
      foreach ($post_keys as $pkey) {
            if ($pkey=='url1' || $pkey=='title_url' || $pkey=='url_title') {
              $post_val = get_post_custom_values($pkey);
      if (empty($post_val)) {
            $link = $perm;
      } else {
            $link = $post_val[0];
    } else {
      $link = $perm;
    echo '<h2><a href="'.$link.'" rel="bookmark" title="'.$title.'">'.$title.'</a></h2>';

Once done, open your index.php file and replace the standard code for printing titles:

<h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></h2>

by a call to our newly created print_post_title() function:

<?php print_post_title() ?>

Now, whenever you feel like let your post title leave your blog and point someplace else, just scroll down in your post writing screen, create or select a custom key named url1 or title_url or url_titleand put that external URL in value box.

 <?php if ($post->ID == 17) {
    echo '<meta name="robots" content="noindex">';

How to: Easily get the value of a custom field

You have to paste it on your theme¬†functions.php¬†file. If your theme doesn’t have a file named¬†functions.php, create one.

function get_custom_field_value($szKey, $bPrint = false) {
    global $post;
    $szValue = get_post_meta($post->ID, $szKey, true);
    if ( $bPrint == false ) return $szValue; else echo $szValue;

Now, to call the function and get your custom field value, use the following code:

<?php if ( function_exists('get_custom_field_value') ){
        get_custom_field_value('featured_image', true);
} ?>

First, we use the php function_exists() function to make sure the get_custom_field_value function is defined on our theme. If it is, we use it. The first argument is the custom field name (here,featured_image) and the second let you echo the value (true) or get it for further use in php (false).
