Change the “Continue reading” Text

Our next customization is to change the “read more” text, which by default is “Continue reading”. You might want it to say “Learn more”, “Read more”, “Discover more”, or whatever. The choice is yours. In this episode, you and I will walk through how to:

• Identify the ID for the text.
• Discover that it’s a filterable event, meaning you need to know the event’s name and then register your callback to it.
• Identify what the event’s name is for the above ID.

The “read more” text is rendered using beans_output() function. Looking at its documentation, notice that it accepts an ID and concatenates the suffix of '_output' to it. That is the filter event’s name. Okay?

That means you need to identify the ID that’s used with beans_output(). How do you do that?

1. Turn on development mode and then look at the comment around the text within the browser.
2. Look at the code.

Option 1: Using the Comment

As we saw in the last episode, when you turn on “development mode”, Beans adds the IDs into the HTML markup as either a comment or data attribute. For beans_output(), we use an HTML comment.

For the given HTML, what is the ID?

<a href="http://beansreadmore.local/i-love-beans/" class="more-link" data-markup-id="beans_post_more_link">
     <!-- open output: beans_post_more_link_text -->
     Learn more
     <!-- close output: beans_post_more_link_text -->
</a>

It’s 'beans_post_more_link_text'. Therefore, the event’s name would be 'beans_post_more_link_text_output'.

Option 2: Beans Code

The other option is to look in the code and find where “Continue reading” is being rendered. Then you can copy the ID.

The Code

add_filter( 'beans_post_more_link_text_output', 'beans_child_change_read_more_text' );
/**
 * Change the "read more" text to "Learn more".
 *
 * @since 1.0.0
 *
 * @param string $text "Read more" text
 *
 * @return string
 */
function beans_child_change_read_more_text($text) {
	return 'Learn more';
}

Here you can use add_filter() or beans_add_filter().
