Author page Not Found

Problem: Clicking on the author name link (Ex.: http://www.leonardowood.com/author/Leonardo%20Wood/) in posts shows Page Not Found.

Solution:

The author link is supposed to be http://www.leonardowood.com/author/leonardo-wood/

Add the following to your theme's functions.php, reload your site twice.

global $wpdb;
 $wpdb->query("UPDATE `{$wpdb->users}` SET `user_nicename`='leonardo-wood' WHERE `ID`='1'");

In the above replace "leonardo-wood" with your user nicename (User name in small case with hypens between spaces).

The above also assumes that ID of user in question is 1. This can be checked via phpMyAdmin in wp_users table.

After ensuring that this has been fixed, remove the above code from functions.php.

query_posts() examples

References:

Category ID can be seen by going to Posts -> Categories, placing the mouse cursor on desired category and observing the number at the end of URL in the browser status bar.

Only posts from a certain category should appear on Posts page

How to: Edit your theme's index.php.

Ex.: Change

	<?php if ( have_posts() ) : ?>
		<?php while ( have_posts() ) : // The Loop ?>
			<?php the_post(); ?>

to

	<?php if ( have_posts() ) : ?>
	<?php $paged = (get_query_var('paged')) ? get_query_var('paged') : 1; query_posts("cat=1&paged=$paged"); ?>
		<?php while ( have_posts() ) : // The Loop ?>
			<?php the_post(); ?>

In the above, change "1" to the ID of category from which posts should be shown. Posts from all other categories won't appear.

Category ID can be seen by going to Posts -> Categories, placing the mouse cursor on desired category and observing the number at the end of URL in the browser status bar.

Posts from a certain category should be excluded from Posts page

How to: Edit your theme's index.php.

Ex.: Change

	<?php if ( have_posts() ) : ?>
		<?php while ( have_posts() ) : // The Loop ?>
			<?php the_post(); ?>

to

	<?php if ( have_posts() ) : ?>
	<?php $paged = (get_query_var('paged')) ? get_query_var('paged') : 1; query_posts("cat=-24&paged=$paged"); ?>
		<?php while ( have_posts() ) : // The Loop ?>
			<?php the_post(); ?>

In the above, change "24" to the ID of category from which posts should NOT be shown. Posts from all other categories will appear.

Show only the first 2000 characters of latest post on posts page

Note: By using this method, HTML formatting and images etc will be shown in the text and will not get stripped. i.e., this is like using the_content() and not the_excerpt().

1. Add the following at the end of your theme's functions.php before the closing PHP tag:

function the_content_limit($max_char, $more_link_text = '(more...)', $stripteaser = 0, $more_file = '') {
    $content = get_the_content($more_link_text, $stripteaser, $more_file);
    $content = apply_filters('the_content', $content);

   if (strlen($_GET['p']) > 0) {
      echo $content;
   }
   else if ((strlen($content)>$max_char) && ($space = strpos($content, " ", $max_char ))) {
        $content = substr($content, 0, $space);
        echo $content = $content . " <a href='"; the_permalink(); echo "'>".$more_link_text."</a>";
   }
   else {
      echo $content;
   }
}

2. Edit theme's home.php.

Add

<?php if ( is_home() ) {
							$paged = (get_query_var('paged')) ? get_query_var('paged') : 1; query_posts("posts_per_page=1&paged=$paged"); 
							}?>

above

<?php while ( have_posts() ) : // The Loop ?>

3. Replace the_content() or the_excerpt() with

<?php the_content_limit(2000, '...<br/><br/>Read the entire article'); ?>

Note: In some themes, the_content() will be like <?php the_content( __( 'Read More→', 'it-l10n-BuilderChild-Classen' ) ); ?>

Show posts in alphabetical order (A to Z)

Edit the appropriate template file. For example, if you want this only in category and archive pages then edit child theme's archive.php. If this file is not present, copy it from parent directory.

Add

<?php $paged = (get_query_var('paged')) ? get_query_var('paged') : 1; query_posts("orderby=title&order=ASC&paged=$paged"); ?>

above

<?php if ( have_posts() ) : ?>

How to add a Read More link at end of excerpts

Edit theme's templates like index.php.

Replace

<?php the_excerpt(); ?>

with

<?php the_excerpt(); ?><span class="readmore"><a href="<?php the_permalink(); ?>">(Read More ...)</a></span>

How to make shortcodes work in manual excerpts

Add the following before closing PHP tag in functions.php:

add_filter('the_excerpt', 'do_shortcode');

Note: If a extension (in Builder) is being used, then functions.php is the one inside extension's directory.
