Thank you for your advice.

Your code works well.

I do appreciate it every time.

You can customze two file form-reply.php and form-topic.php .

bbress> templates > default > form-topic.php at line 170

<input name="bbp_topic_subscription" id="bbp_topic_subscription" type="checkbox" value="bbp_subscribe" <?php bbp_form_topic_subscribed(); ?> />
↓
<input name="bbp_topic_subscription" id="bbp_topic_subscription" type="checkbox"checked value="bbp_subscribe" <?php bbp_form_topic_subscribed(); ?> />

bbress> templates > default > form-reply.php at line 104

<input name="bbp_topic_subscription" id="bbp_topic_subscription" type="checkbox" value="bbp_subscribe"<?php bbp_form_topic_subscribed(); ?> />
↓
<input name="bbp_topic_subscription" id="bbp_topic_subscription" type="checkbox"checked value="bbp_subscribe"<?php bbp_form_topic_subscribed(); ?> />

Then the topic and reply are automatically subscribed simply.
But the participant can uncheck the checkbox about subscription by himself.
If you do not want participant uncheck the checkbox, you can delete checkbox by CSS.

Put these customized files in your child theme’s folder-bbpress.

How about the GD bbPress Attachments plugin?

GD-bbpress-attachment

[Julia]

How about this code?

type="checkbox" ⇒　type="checkbox"checked

You can customize the form-reply.php and form-topic.php .

<input name="bbp_topic_subscription" id="bbp_topic_subscription" type="checkbox"checked value="bbp_subscribe"<?php bbp_form_topic_subscribed(); ?> />

You can change the code simply and put both files in your child theme’s bbpress folder.

[Julia]

Your code works quite well. How simple they are!
I tried to customize it , but I couldn’t. I couldn’t get strpos code.

Thank you for your kindness.

‘reply page’ means content-single-topic.php .

<?php bbp_topic_subscription_link(); ?>

includes> topics > template.php

function bbp_topic_subscription_link( $args = array() ) {
	echo bbp_get_topic_subscription_link( $args );
}

	/**
	 * Get the topic subscription link
	 *
	 * A custom wrapper for bbp_get_user_subscribe_link()
	 *
	 * @since 2.5.0 bbPress (r5156)
	 * @since 2.6.0 bbPress (r6308) Add 'redirect_to' support
	 */
	function bbp_get_topic_subscription_link( $args = array() ) {

		// Defaults
		$retval      = false;
		$user_id     = bbp_get_current_user_id();
		$redirect_to = bbp_is_subscriptions()
			? bbp_get_subscriptions_permalink( $user_id )
			: '';

		// Parse the arguments
		$r = bbp_parse_args( $args, array(
			'user_id'     => $user_id,
			'object_id'   => bbp_get_topic_id(),
			'object_type' => 'post',
			'before'      => ' | ',
			'after'       => '',
			'subscribe'   => esc_html__( 'Subscribe',   'bbpress' ),
			'unsubscribe' => esc_html__( 'Unsubscribe', 'bbpress' ),
			'redirect_to' => $redirect_to
		), 'get_topic_subscribe_link' );

		// Get the link
		$retval = bbp_get_user_subscribe_link( $r );

		// Filter & return
		return apply_filters( 'bbp_get_topic_subscribe_link', $retval, $r, $args );
	}

I could get the code to set on the thumbnails in the topic index page using GD bbPress Attachments.

function action_bbp_topic_row_actions() { 

    $medias = get_attached_media( 'image', bbp_get_topic_id() );
    
    foreach($medias as $media){
    the_attachment_link( $media->ID,false );
    }
} 
add_action( 'bbp_theme_before_topic_title', 'action_bbp_topic_row_actions', 10, 0 ); 

[Julia]

Add other method.
I have succeeded to set the images on topic index page.
but I have no idea to change images to thumbnails.

Do you have any ideas for thumbnails?

 
function action_bbp_topic_row_actions() { 
   if ( have_posts() ) while ( have_posts() ) : the_post();
  
    $medias = get_attached_media( 'image', bbp_get_topic_id() );
    foreach($medias as $media){
      the_attachment_link( $media->ID );
    }
   endwhile;
  }
add_action( 'bbp_theme_before_topic_title', 'action_bbp_topic_row_actions', 10, 0 ); 

[Julia]

I appreciate it.

It works completely.

Thank you for your genius.

[Julia]

Thank you for your help. Thanks to your code, I manage to set up open close button in the reply page .
So in bbp style pack or my customized code, the open close status button sets on all comments in the reply page.
It would be un-displayable by using CSS code except for top comment[topic author comment].

Do you have some sample code to hide unnecessary open close status buttons by CSS(Cascading Style Sheet) ?

Example

//topic author		
<a href="http://～　　　#post-1762" class="bbp-reply-header">#1762</a>
class="bbp-topic-close-link"
//------------------------------------------------------------------------
//reply first
<a href="http://～　　 #post-1763" class="bbp-reply-header">#1763</a>
class="bbp-topic-close-link"

#bbpress-forums  XXX.bbp-topic-close-link {
        display: none;
  }

[Julia]

I see. Thank you for your kindness.

[Julia]

bbp_theme_before_forum_title

I could not do it.
It is same loop with bbp_theme_after_forum_title

bbpress.org shows that “23. Show the bbPress forum search everywhere”.
Layout and functionality – Examples you can use

But it may be that there is not hook point to set on the search form above of the title.

[Julia]

Thank you for your help.
But your code does not work correctly.

bbp_template_before_replies_loop
in reply page
[Title]
[Breadcrumb]
[Search form]

bbp_theme_after_forum_title
in forum page
[Forum title]
[Search form]
[Forum title]
[Search form]
[Forum title]
and loop

These are not my target.
