how 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; }

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.

$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);

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() ?>
