RSS feed for this topichow to enlight searched text in search results
Open your search.php temalate file, find the the_title() function, then replace it with the following:
echo $title;
Now, just before the modified line, add this code:
<?php
$title = get_the_title();
$keys= explode(" ",$s);
$title = preg_replace('/('.implode('|', $keys) .')/iu',
'< strong class= " search-excerpt"> \ 0 </strong >',
$title);
?>
Save the search.php file and apply your class to the style.css with the following class
strong.search-excerpt { background: yellow; }
How to add body class to WordPress themes
Add this to your functions file:
<?php function mytheme_body_control() { if (is_home()) { echo 'id="home"'; } elseif (is_single()) { echo 'id = "single"'; } elseif (is_search()) { echo 'id="search"'; } elseif (is_archive()) { echo 'id="archive"'; } } ?>
then in header add this after the closing header tag
<body <?php mytheme_body_control(); ?>>
Complete separate style.css for each page template
<?php
if ( is_page_template('page.php')) { ?>
<link rel="stylesheet" type="text/css" href="<?php bloginfo('template_directory'); ?>/style.css" />
<?php } ?>
<?php
if ( is_page_template('nosidebar.php')) { ?>
<link rel="stylesheet" type="text/css" href="<?php bloginfo('template_directory'); ?>/nosidebar.css" />
<?php } ?>
<?php
if ( is_page_template('nopostpage.php')) { ?>
<link rel="stylesheet" type="text/css" href="<?php bloginfo('template_directory'); ?>/nopostpage.css" />
<?php } ?>
<?php
if ( is_page_template('homepage.php')) { ?>
<link rel="stylesheet" type="text/css" href="<?php bloginfo('template_directory'); ?>/homepage.css" />
<?php } ?>
This will assign a different css file for each of your pages,
of course all the page templates and its CSS files have to be created before using.
Display the last image attached to WP posts via shortcode
add this code to your functions.php file
<?php
function sc_postimage($atts, $content = null) {
extract(shortcode_atts(array(
"size" => 'thumbnail',
"float" => 'none'
), $atts));
$images =& get_children( 'post_type=attachment&post_mime_type=image&post_parent=' . get_the_id() );
foreach( $images as $imageID => $imagePost )
$fullimage = wp_get_attachment_image($imageID, $size, false);
$imagedata = wp_get_attachment_image_src($imageID, $size, false);
$width = ($imagedata[1]+2);
$height = ($imagedata[2]+2);
return '<div class="postimage" style="width: '.$width.'px; height: '.$height.'px; float: '.$float.';">'.$fullimage.'</div>';
}
add_shortcode("postimage", "sc_postimage");
?>
than just add this shortcode via your wp post admin panel
[postimage]
Link to some external ressource in post title
add this code to your functions.php file
<?php
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.'</h2>'; }
?>
open your index.php/home php template, 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(); ?></ h2>
by a call to the new print_post_title() function:
<?php print_post_title() ?>
Get thumbnails from specific posts
<ul >
<?php //The name of custom field you'd like to get, don't forget to change it $custom_field_name = "featuredimg"; //Cool sql request $sql = "SELECT p.comment_count, p.ID, m.post_id, m.meta_key, m.meta_value FROM wp_posts p, wp_postmeta m WHERE p.ID = m.post_id LIMIT 0,10;"; $result = $wpdb->get_results($sql); foreach ($result as $topten) { $postid = $topten->ID; $title = $topten->post_title; $commentcount = $topten->comment_count; if ( $topten->meta_key == $custom_field_name) { $img = 'meta_value.'" alt=""/>'; ?>
<li >< a href= "<?php echo get_permalink($postid); ?>">
<?php echo $img; ?>
</li >
<?php } } ?> </ul >

Manually define to show full post or excerpt on your homepage
On the index.php file, replace the current loop by the following:
<?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
the_title();
the_content();
} else {
// No custom field set, let's display an excerpt
the_title();
the_excerpt();
endwhile;
endif;
?>
