Smart 404

描述

Save your visitors from unhelpful 404 errors!

Instead of quickly giving up when a visitor reaches content that doesn’t exist, make an effort to guess what they were
after in the first place. This plugin will perform a search of your posts, pages, tags and categories, using keywords from the requested
URL. If there’s a match, redirect to that content instead of showing the error. If there’s more than one match, the
404 template can use some template tags to provide a list of suggestions to the visitor.

See the Smart 404 homepage for more information.

Template tags

smart404_has_suggestions

Returns true if there are some suggestions, false otherwise

smart404_get_suggestions

Retrieve an array of post objects for rendering manually.

smart404_suggestions

Draw a list of suggested posts.

Pass the parameter “list” to render suggestions as a list.

smart404_loop

Query posts for use in a Loop. Eg:

<?php smart404_loop(); ?>
<?php while (have_posts()) : the_post(); ?>
    <h2><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h2>
    <?php the_excerpt(); ?>
<?php endwhile; ?>

Note that the loop will not display pages correctly, as it is not built to support them. It is recommended that if you use
a loop like that above, do not enable searching of pages.

smart404_get_search_terms

Retrieve an array of search terms used to populate the suggestions list, for use with contextual highlighting, etc.
