我有这段代码，它在wordpress中的循环外运行摘录。
<?php
function get_excerpt_by_id($post_id){
$the_post = get_post($post_id); //Gets post ID
$the_excerpt = $the_post->post_content; //Gets post_content to be used as a basis for the excerpt
$excerpt_length = 35; //Sets excerpt length by word count
$the_excerpt = strip_tags(strip_shortcodes($the_excerpt)); //Strips tags and images
$words = explode(' ', $the_excerpt, $excerpt_length + 1);
if(count($words) > $excerpt_length) :
array_pop($words);
array_push($words, '…');
$the_excerpt = implode(' ', $words);
endif;
$the_excerpt = '<p>' . $the_excerpt . '</p>';
return $the_excerpt;
}
?>
正如你所看到的，它删除了所有的内容，比如图像和其他东西，只留下文本，但当它这样做时，它也会输出很多空白（返回）。我试着用''n，''t，''r删除它们，但很明显，我不知道把代码放在哪里才能使其工作。你能帮我做这个吗？
尝试：
<?php
function get_excerpt_by_id($post_id){
$the_post = get_post($post_id); //Gets post ID
$the_excerpt = $the_post->post_content; //Gets post_content to be used as a basis for the excerpt
$excerpt_length = 35; //Sets excerpt length by word count
$the_excerpt = strip_tags(strip_shortcodes($the_excerpt)); //Strips tags and images
$words = explode(' ', $the_excerpt, $excerpt_length + 1);
if(count($words) > $excerpt_length) :
array_pop($words);
array_push($words, '…');
$the_excerpt = implode(' ', $words);
endif;
$the_excerpt = '<p>' . $the_excerpt . '</p>';
// LOOK HERE
$the_excerpt = str_replace("'r", "", $the_excerpt); // Replace carriage returns
$the_excerpt = str_replace("'n", "", $the_excerpt); // Replace new lines
// .. etc
return $the_excerpt;
}
?>
试试这个
<?php
function get_excerpt_by_id($post_id){
$the_post = get_post($post_id); //Gets post ID
$the_excerpt = $the_post->post_content; //Gets post_content to be used as a basis for the excerpt
$the_excerpt = apply_filters('the_excerpt', $the_excerpt);
return $the_excerpt;
}
?>
