如何在此代码中添加target =“ _ blank”

Question

PHP

<p class="postmeta">
    <?php if ( 'post' == get_post_type() ) : // Hide category and tag text for pages on Search ?>
        <?php
            /* translators: used between list items, there is a space after the comma */
            $categories_list = get_the_category_list( __( ', ', 'gridster' ) );
            if ( $categories_list && gridster_categorized_blog() ) :
        ?>
            <?php printf( __( '%1$s', 'gridster' ), $categories_list ); ?>
        <?php endif; // End if categories ?>


    <?php endif; // End if 'post' == get_post_type() ?>
</p>

It produces this HTML:

<p class="postmeta">
    <a href="http://myurl.com/category/blahblah/" title="View all posts in blahblah" rel="category tag">blahblah</a>            
</p>

I tried reading the wordpress codex but I really couldn't figure out how to add target="_blank" into the a tag. I'm trying to add that so that the link will open in a new tab.

Does anyone know how to do this?

Answer 1

Use this filter to apply _blank to get_the_category_list() , because get_the_category_list() runs it output through the filter the_category

add_filter('the_category', 'wp55_the_category');
function wp55_the_category($cat_list) {
    return str_ireplace('<a', '<a target="_blank"', $cat_list);
}

add this in your functions.php file. For more information take a look on these filters http://codex.wordpress.org/Plugin_API/Filter_Reference#Database_Reads_3

Answer 2

get the category list is meant to be very basic. You have 3 choices:

1) change that function to something else such as using http://codex.wordpress.org/Function_Reference/wp_list_categories

2) parse the returned $categories_list using PHP

3) use some javascript - let's say you have jquery in your them then you could just add this somewhere:

jQuery.ready(function() {
 jQuery('.postmeta a').attr('target','_blank');
});
