【问题描述】:
需要 PHP 帮助,所以我遇到了一个 wordpress 问题我有显示标题内容并继续阅读文本的功能,我需要在标题中放置继续阅读文本的链接并隐藏继续阅读文本。这是生成以下标题的文件中的代码:
function whisper_entry_title2()
{
if ( !( $title = get_the_title() ) )
return;
// Check on singular pages
$is_single = is_singular() && !is_page_template( 'tpl/blog.php' ) && !is_page_template( 'tpl/blog-boxes.php' );
// Allow to config via global variable
if ( isset( $whisper['is_single'] ) )
$is_single = $whisper['is_single'];
$tag = $is_single ? 'h1' : 'h2';
$title = sprintf( '<b class="black">%4$s</b>', $tag, get_permalink(), the_title_attribute( 'echo=0' ), $title );
echo apply_filters( __FUNCTION__, $title );
}
这里是生成继续阅读的部分代码:
function whisper_content_limitoffer1( $num_words, $more = '...', $echo = true )
{
$content = get_the_content();
// Strip tags and shortcodes so the content truncation count is done correctly
$content = strip_tags( strip_shortcodes( $content ), apply_filters( 'whisper_content_limit_allowed_tags', '<script>,<style>' ) );
// Remove inline styles / scripts
$content = trim( preg_replace( '#<(s(cript|tyle)).*?</\1>#si', '', $content ) );
// Truncate $content to $max_char
$content = wp_trim_words( $content, $num_words );
if ( $more )
{
//$event_id = get_post_meta(get_the_ID(),'event_id', TRUE);
//$link="http://example.com/wp/events-offers/";
$output = sprintf(
'<p class="event2-cf-oe">%s <a href="%s" class="more-link right o_6" title="%s">%s</a></p>',
$content,
get_permalink(),
sprintf( __( 'Continue reading "%s"', 'whisper' ), the_title_attribute( 'echo=0' ) ),
$more
);
}
else
{
$output = sprintf( '<p class="event2-cf-oe">%s</p>', $content );
}
// Still display post formats differently
$output = whisper_post_formats_content( $output );
if ( $echo )
echo $output;
else
return $output;
}
