    Hi. I need some help! I want to do something like this:
    1) find same words, which are set as tag, in post contents
    2) wrap that specific text with <span>

    I want to highlight or change style of specific text in post content that are same as in Tags.
    And each Tags and contents are in Japanese character.

    I tried to find some solution by myself, but nothing works… ;(

    Thank you!

  • Hi Nathan Nawbi,

    Add this to your function.php file in your template directory

    function ncej_special_content( $id, $content ) {
$tags = get_the_tags( $id );
if ( $tags ) {

foreach ( $tags as $tag ) {
$old_tags[] = $tag->name;
$new_tags[] = '<span class="special-tag">' . $tag->name . '</span>';
}

$content = apply_filters( 'the_content', $content );

// Do the replacing
$content = str_replace( $old_tags, $new_tags, $content );

$content = str_replace( ']]>', ']]&gt ;', $content );

echo $content;

} else {

$content = apply_filters( 'the_content', $content );

// Do the replacing
$content = str_replace( ']]>', ']]&gt ;', $content );

echo $content;

}
}

    Now do the loop like this 

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

// other query here e.g the_title() and so on.

// instead of using the_content() use ncej_special_content()

ncej_special_content( get_the_ID(), get_the_content() );

<?php endwhile; ?>
<?php endif; ?>

    You can go ahead and style the class “special-tag” the way you like.

    I hope this helps.

    Cheers.
