What Is The Need?
More often than not, a WordPress powered blog is (a big/small) part of a website and often times, it becomes necessary to display post-excerpts (from a diary or a journal, etc.) in the main page. This can often help visitors/readers get a glimpse of what is on offer (like a menu at a restaurant) and decide if they want to actually read it.
How To Get It Done?
Let us suppose that the website has a main page, called index.php (URL: http://www.your-site.com/index.php), and that the WordPress powered blog is served from wordpress (URL: http://www.your-site.com/wordpress/) folder. Let us suppose that we need to display the excerpts of the latest 5 posts in index.php. To that effect, let us create a file – wp_latest_posts.php – with following contents:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 | <!--?php # wp_latest_posts.php # Displays a pre-set number of post-excerpts in a page # outside of wordpress folder. # This script must reside in the same folder as of index.php # (http://www.your-site.com/index.php) # MySQL connection details (refer to wp-config.php) $host = "localhost"; $dbuser = "WORDPRESS_USER"; $dbpasswd = "WORDPRESS_PASSWORD"; $database = "WORDPRESS_DATABASE"; $table_prefix = 'wp_'; $table_posts = $table_prefix . 'posts'; # Connect to MySQL $connect = mysql_connect($host, $dbuser, $dbpasswd) or die(mysql_error()); mysql_select_db($database,$connect) or die(mysql_error()); # Number of post-excerpts to be displayed on index.php $num_latest = 5; # Perform the query # This selects everything from '$table_posts' table which are # PUBLISHED and NOT PAGES, and reverse orders them by POST DATE. $sql = "SELECT * FROM $table_posts WHERE post_status LIKE "; $sql .= "\"%publish%\" AND post_type != 'page' "; $sql .= "ORDER BY post_date DESC LIMIT $num_latest "; $result = mysql_query($sql) or die('Invalid Query:' . mysql_errno() . mysql_error()); $nresults = mysql_num_rows($result); # Display results # The results are displayed as an un-ordered list. Can be modified # to meet specific requirements with basic knowledge of HTML print "</p> <h3>News Clips</h3> <p>\n"; print "</p> <ul>\n"; while ($post_details = mysql_fetch_array($result)) { # Store the values in varaibles $post_guid = $post_details['guid']; $post_title = $post_details['post_title']; $post_date = $post_details['post_date']; $post_content = $post_details['post_content']; # Convert Date in to 'July 1, 2008' format # Refer to PHP's date manual for more options $post_date = strtotime($post_date); $post_date = date('F j, Y', $post_date); # Generate post-excerpt (say the first 150 characters # of post-content) $post_content = strip_tags($post_content, '<br> <sub> </sub>'); if (strlen($post_content) > 150 ){ $post_excerpt = mb_substr($post_content, 0, 147) . '... [More]'; } else { $post_excerpt = $post_content; } # Display the entry details # One can decorate these with a basic working knowledge of CSS print "</p> <li> <br ?--> |
$post_title>
$post_date
$post_excerpt
\n”; } print ”
\n\n”; # Free up resources and close the connection to the database mysql_free_result($result); mysql_close($connect); ?>
To include this wp_latest_posts.php in index.php, one may use the following syntax at an appropriate place:
1 | include('wp_latest_posts.php'); |
