@megainfo,

Sorry, I most certainly wasn’t clear. What you provided works in the Group’s main page where the description length is fine (which is good, since I may want to modify that later).

What I wanted to do was specify the length of excerpt on the group directory page. So, given what you laid out, is there a hook that could be applied for that location? The groups loop is calling bp_group_description_excerpt().

Hopefully, that’s clearer. Thanks again.

@megainfo,

Thanks. That does work to produce the excerpt at the right spot. However, it does not properly handle not cutting words in the middle nor putting the […] at the end. The following function in the core file (mentioned in my first comment) does that:

`function bp_create_excerpt( $text, $length = 225, $options = array() ) {
// Backward compatibility. The third argument used to be a boolean $filter_shortcodes
$filter_shortcodes_default = is_bool( $options ) ? $options : true;

$defaults = array(
‘ending’ => __( ‘ […]’, ‘buddypress’ ),
‘exact’ => false,
‘html’ => true,
‘filter_shortcodes’ => $filter_shortcodes_default
);
$r = wp_parse_args( $options, $defaults );
extract( $r );

// Save the original text, to be passed along to the filter
$original_text = $text;

// Allow plugins to modify these values globally
$length = apply_filters( ‘bp_excerpt_length’, $length );
$ending = apply_filters( ‘bp_excerpt_append_text’, $ending );

// Remove shortcodes if necessary
if ( !empty( $filter_shortcodes ) )
$text = strip_shortcodes( $text );

// When $html is true, the excerpt should be created without including HTML tags in the
// excerpt length
if ( !empty( $html ) ) {
// The text is short enough. No need to truncate
if ( mb_strlen( preg_replace( ‘//’, ”, $text ) ) <= $length ) {
return $text;
}

$totalLength = mb_strlen( strip_tags( $ending ) );
$openTags = array();
$truncate = ”;

// Find all the tags and put them in a stack for later use
preg_match_all( ‘/(]*>)?([^]*)/’, $text, $tags, PREG_SET_ORDER );
foreach ( $tags as $tag ) {
// Process tags that need to be closed
if ( !preg_match( ‘/img|br|input|hr|area|base|basefont|col|frame|isindex|link|meta|param/s’, $tag[2] ) ) {
if ( preg_match( ‘/]*>/s’, $tag[0] ) ) {
array_unshift( $openTags, $tag[2] );
} else if ( preg_match(‘/]*>/s’, $tag[0], $closeTag ) ) {
$pos = array_search( $closeTag[1], $openTags );
if ( $pos !== false ) {
array_splice( $openTags, $pos, 1 );
}
}
}
$truncate .= $tag[1];

$contentLength = mb_strlen( preg_replace( ‘/&[0-9a-z]{2,8};|&#[0-9]{1,7};|&#x[0-9a-f]{1,6};/i’, ‘ ‘, $tag[3] ) );
if ( $contentLength + $totalLength > $length ) {
$left = $length – $totalLength;
$entitiesLength = 0;
if ( preg_match_all( ‘/&[0-9a-z]{2,8};|&#[0-9]{1,7};|&#x[0-9a-f]{1,6};/i’, $tag[3], $entities, PREG_OFFSET_CAPTURE ) ) {
foreach ( $entities[0] as $entity ) {
if ( $entity[1] + 1 – $entitiesLength <= $left ) {
$left–;
$entitiesLength += mb_strlen( $entity[0] );
} else {
break;
}
}
}

$truncate .= mb_substr( $tag[3], 0 , $left + $entitiesLength );
break;
} else {
$truncate .= $tag[3];
$totalLength += $contentLength;
}
if ( $totalLength >= $length ) {
break;
}
}
} else {
if ( mb_strlen( $text ) <= $length ) {
return $text;
} else {
$truncate = mb_substr( $text, 0, $length – mb_strlen( $ending ) );
}
}

// If $exact is false, we can’t break on words
if ( empty( $exact ) ) {
$spacepos = mb_strrpos( $truncate, ‘ ‘ );
if ( isset( $spacepos ) ) {
if ( $html ) {
$bits = mb_substr( $truncate, $spacepos );
preg_match_all( ‘//’, $bits, $droppedTags, PREG_SET_ORDER );
if ( !empty( $droppedTags ) ) {
foreach ( $droppedTags as $closingTag ) {
if ( !in_array( $closingTag[1], $openTags ) ) {
array_unshift( $openTags, $closingTag[1] );
}
}
}
}
$truncate = mb_substr( $truncate, 0, $spacepos );
}
}
$truncate .= $ending;

if ( $html ) {
foreach ( $openTags as $tag ) {
$truncate .= ”;
}
}

return apply_filters( ‘bp_create_excerpt’, $truncate, $original_text, $length, $options );

}
add_filter( ‘bp_create_excerpt’, ‘stripslashes_deep’ );
add_filter( ‘bp_create_excerpt’, ‘force_balance_tags’ );
`

So, using that function in functions.php in the following does not work (I think it’s similar to a circular reference error in Excel):

add_filter( ‘bp_get_group_description_excerpt’, ‘bp_create_excerpt’);

This results in the white screen of death, though it’s probably close. Anyway, thanks for your help.

@illumination2025,

The following plugin works great:
