Disable author meta box for specific pages and posts – WordPress

[gard]
Sometimes its necessary to give your posts or pages switches to turn on and off specific template elements on your site. WordPress makes it really easy:

 

If not already done, activate the Custom fields on the Screen Options menue at the upper right corner of your post:

Add New Post ‹ XSimulator — WordPress

Than create any field and value, e.g.:
Name: hide-author
Value: 0

You can call the name as you want it. We define it in the template next.

custom fields in WordPress

 

Now we open content.php and go to line 60:

<?php     if ( is_single() && get_the_author_meta( 'description' ) && is_multi_author() ) :?>
			<?php get_template_part( 'author-bio' ); ?>
		 <?php endif; ?>

Change it so something like:

if ( is_single() && get_post_meta($post->ID,  'hide-author', true) != '1') :
                    ?>
			<?php get_template_part( 'author-bio' ); ?>
		<?php endif; ?>

As you can see, you can grab  the new custom field and create a condition with:

 get_post_meta($post->ID,  'hide-author', true) != '1')

Now you can specify in all your posts and pages if you like to disable or enable the author box. Very easy!

WordPress breadcrumbs without plugin

Open your theme functions.php and add the following code:

function xsimu_breadcrumb() {
        echo ' <ul id="breadcrumbs">';
    if (!is_home()) {
        echo '<li> <a href="';
        echo get_option('home');
        echo '">';
        echo 'Home';
        echo "</a><span class='separator'>»</span></li>";
        if (is_category() || is_single()) {
            echo ' <li>';
            the_category('<span class="separator">»</span></li><li> ');
            if (is_single()) {
                echo "</li><li><span class='separator'>»</span>";
                the_title();
                echo '</li>';
            }
        } elseif (is_page()) {
            echo '<li>';
            echo the_title();
            echo '</li>';
        }
    }
    elseif (is_tag()) {single_tag_title();}
    elseif (is_day()) {echo"<li>Archive for "; the_time('F jS, Y'); echo'</li>';}
    elseif (is_month()) {echo"<li>Archive for "; the_time('F, Y'); echo'</li>';}
    elseif (is_year()) {echo"<li>Archive for "; the_time('Y'); echo'</li>';}
    elseif (is_author()) {echo"<li>Author Archive"; echo'</li>';}
    elseif (isset($_GET['paged']) && !empty($_GET['paged'])) {echo "<li>Blog Archives"; echo'</li>';}
    elseif (is_search()) {echo"<li>Search Results"; echo'</li>';}
    echo '</ul>';
}

Add the following function in one of your templates. Most times you will use the header.php

<?php xsimu_breadcrumb(); ?>

Congratulations. You are done;)

Limit revisions in WordPress 3.6

In WP older than 3.6 it´s possible to deactivate or limit revisions in WordPress with the entry

define('WP-POST_REVISIONS', 100);

It seems that it is not working any longer in WP 3.6. Fortunately there is a nice little plugin that works very reliable and is able to delete a whole bunch of old revisions between two dates:

Pagination for WordPress without Plugin

When i started the creating process of this theme i considered to integrate one of the popular WordPress plugins for pagination. I than  decided to publish the XSimulator theme for free and i felt that it could lead to any problems and issues for someone else to make a similar looking theme when the requirements  are a lot of different plugins he must install first. Fortunately i found a great programmed script which is very easy to implement and powerful.

Open your functions.php and create a new function:

/* Adds pagination 
 * 
 * @since XSimulator 1.0
 * @param $range total list of pages 
 * @param $range count of maximum page links from left and right side of the current page link.
 * @bool $show_one_page_hint shows a text like: page 1 of 6
 * @bool $show_one_pager Do not show nav arrows
 * 
 */
function xsimu_pagination($range = 3, $show_one_pager = true, $show_page_hint = false)
{
    global $wp_query;
    $num_of_pages = (int)$wp_query->max_num_pages;

    if(!is_single() && $num_of_pages > 1)
    {
        $current_page = get_query_var('paged') === 0 ? 1 : get_query_var('paged');
        $num_of_display_pages = ($range * 2) + 1;        

        $output = '<div id="pagination">';

        if($show_page_hint)
        {
            $output .= '<span>Page ' . $current_page . ' of ' . $num_of_pages . '</span>';
        }

		if($current_page > 2 && $current_page > $range + 1 && $num_of_display_pages < $num_of_pages)
		{
			$output .= '<a href="' . get_pagenum_link(1) . '" title="Page 1 - Latest article">«</a>';
		}
		if($show_one_pager && $current_page > 1)
		{
			$output .= '<a href="' . get_pagenum_link($current_page - 1) . '" title="Page ' . ($current_page - 1) . ' - Latest Artikel">‹</a>';
		}

		for($i = 1; $i <= $num_of_pages; $i++)
		{
			if($i < $current_page + $range + 1 && $i > $current_page - $range - 1)
            {
				if($current_page === $i)
				{
					$output .= '<span class="current">' . $i . '</span>';
				}
				else
				{
					$output .= '<a href="' . get_pagenum_link($i) . '" title="Page ' . $i . '" >' . $i . '</a>';
				}
            }
		}

		if($show_one_pager && $current_page < $num_of_pages)
		{
			$output .= '<a href="' . get_pagenum_link($current_page + 1) . '" title="Page ' . ($current_page + 1) . ' - Older article">›</a>';
		}
		if($current_page < $num_of_pages - 1 && $current_page + $range < $num_of_pages && $num_of_display_pages < $num_of_pages)
		{
			$output .= '<a href="' . get_pagenum_link($num_of_pages) . '" title="Page ' . $num_of_pages . ' - Older article">»</a>';
		}

		$output .= '</div>';

        return $output;

    }
}

Open the template file where you want to publish your pagination. E.g. category.php

echo xsimu_pagination(2, true, false);

You´re ready:)
