Hi all

Does anyone know of a way to add a function to change the ‘Read More’ text link based on a conditional such as a post tag? So for example for all posts tagged with ‘Photos’ the read more button text could be changed to ‘View Photos’, etc.

I’ve found a couple of functions online but they seem to be theme specific.

Thanks for any help
Greg

Hi there,

Not sure if it will work, but you can try this:
```
add_filter( 'wpsp_read_more_output', function( $output ) {
    if ( ! has_tag( 'your-tag' ) ) {
        return $output;
    }

    return sprintf('<div class="wpsp-read-more"><a title="%1$s" class="%4$s" href="%2$s">%3$s</a></div>',
        the_title_attribute( 'echo=0' ),
        esc_url( get_permalink() ),
        'YOUR CUSTOM TEXT HERE',
        'wp-show-posts-read-more'
    );
} );
```

Unfortunately not, Tom…

Any ideas?

Can you check your error_log file for the exact error?

Thanks Tom, that’s done it!

If I wanted to create custom text for multiple tags and buttons, would you recommend me duplicating this snippet for each or is there a better way to combine into one snippet?

Thanks for your perseverance
Greg

You can use the same filter:
```
add_filter( 'wpsp_read_more_output', function( $output ) {
    if ( has_tag( 'your-tag' ) ) {
        return sprintf('<div class="wpsp-read-more"><a title="%1$s" class="%4$s" href="%2$s">%3$s</a></div>',
            the_title_attribute( 'echo=0' ),
            esc_url( get_permalink() ),
            'YOUR CUSTOM TEXT HERE',
            'wp-show-posts-read-more'
        );
    }

    if ( has_tag( 'another-tag' ) ) {
        return sprintf('<div class="wpsp-read-more"><a title="%1$s" class="%4$s" href="%2$s">%3$s</a></div>',
            the_title_attribute( 'echo=0' ),
            esc_url( get_permalink() ),
            'YOUR CUSTOM TEXT HERE',
            'wp-show-posts-read-more'
        );
    }

    return $output;
} );
```
