输出Wordpress帖子中的第一段

Question

I want to put just the first paragraph of my posts on my index.php

in my functions.php I have

<?php

{
global $post;

$output = get_the_content();

$wanted_number_of_paragraph = 1;

$tmp = explode ('</p>', $output);
for ($i = 0; $i < $wanted_number_of_paragraph; ++$i) {
if (isset($tmp[$i]) && $tmp[$i] != '') {
   $tmp_to_add[$i] = $tmp[$i];
}
}
$output = implode('</p>', $tmp_to_add) . '</p>';

echo $output;

}
?>

then in my index.php

<?php wpden_excerpt(); ?>

However it posts the entire post (including pictures) and not just the first paragraph.

I wold recommend you to use the Wordpress get_extended() function for this purpose. In your post you split the content with the "more" tag, after inside your template you can have something like:

global $post;
// gets the content of your post as an array of 2 parts
$content_parts = get_extended( $post->post_content ); 

and after this you can echo the part before the "more" tag like:

<?=$content_parts['main'];?>

the part after the "more" tag you can echo like:

<?=$content_parts['extended'];?>

Also, if you chose this option I'll recommend you to check the wpautop() , since you may need to wrap these 2 parts with it, for example:

<?=wpautop($content_parts['extended']);?>
