Custom Wordpress Excerpt by two paragraphs - php

Question

I found the answers to limiting the excerpts to only 2 paragraphs or more. However, the code I found only apply to the actual excerpt, not to custom excerpt that I made. I made two excerpts, one for certain posts on front page and another for the posts page. I wanted to add that code to the custom excerpt that I made for the posts page. How do I do that.
Here's my code that I created:
// Create the Custom Excerpts callback
function wpden_excerpt($length_callback = '', $more_callback = '')
{
global $post;
if (function_exists($length_callback)) {
add_filter('excerpt_length', $length_callback);
}
if (function_exists($more_callback)) {
add_filter('excerpt_more', $more_callback);
}
$output = get_the_excerpt();
$output = apply_filters('wptexturize', $output);
$output = apply_filters('convert_chars', $output);
$output = '<p>' . $output . '</p>';
echo $output;
}
// Custom Length
function wpden_mag_len($length) {
return 200;
}
function wpden_more_view($more){
global $post;
return '... <a class="view-article" href="' . get_permalink($post->ID) . '">' . __('', 'wpden') . '</a>';
}
And I called it in my template_post.php:
<?php wpden_excerpt('wpden_mag_len','wpden_more_view'); ?>
The code in question that I wanted to use for my custom wpden_excerpt is either this:
add_filter( 'wp_trim_excerpt', 'my_custom_excerpt', 10, 2 );
function my_custom_excerpt($text, $raw_excerpt) {
if( ! $raw_excerpt ) {
$content = apply_filters( 'the_content', get_the_content() );
$text = substr( $content, 0, strpos( $content, '</p>' ) + 4 );
}
return $text;
}
from this site or from the other stack overflow question
$wpse0001_excerpt = get_the_content('');
$wpse0001_excerpt = strip_shortcodes( $wpse0001_excerpt );
$wpse0001_excerpt = apply_filters('the_content', $wpse0001_excerpt);
// Here we choose how many paragraphs do we want to cutthe excerpt at, This part thanks to Clément Malet
$wpse0001_excerpt = "<p>$wpse0001_excerpt</p>";
$wanted_number_of_paragraph = 2;
$tmp = explode ('</p>', $wpse0001_excerpt);
for ($i = 0; $i < $wanted_number_of_paragraph; ++$i) {
if (isset($tmp[$i]) && $tmp[$i] != '') {
$tmp_to_add[$i] = $tmp[$i];
}
}
$wpse0001_excerpt = implode('</p>', $tmp_to_add) . '</p>';
$wpse0001_excerpt = str_replace(']]>', ']]>', $wpse0001_excerpt);
$excerpt_end = ' ' . ' » ' . sprintf(__( 'Read more about: %s »', 'pietergoosen' ), get_the_title()) . '';
$excerpt_more = apply_filters('excerpt_more', ' ' . $excerpt_end);
//$pos = strrpos($wpse0001_excerpt, '</');
//if ($pos !== false)
// Inside last HTML tag
//$wpse0001_excerpt = substr_replace($wpse0001_excerpt, $excerpt_end, $pos, 0);
//else
// After the content
$wpse0001_excerpt .= $excerpt_end;
return $wpse0001_excerpt;
}
return apply_filters('wpse0001_custom_wp_trim_excerpt', $wpse0001_excerpt, $raw_excerpt);
}
endif;
remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'wpse0001_custom_wp_trim_excerpt');
The thing is that those codes in question apply to the the_excerpt and override the custom excerpt that I made. I tried to format the code like this:
function wpden_excerpt($text = '')
{
global $post;
if ( '' == $text ) {
$text = get_the_content('');
$text = apply_filters('the_content', $text);
$text = str_replace('\]\]\>', ']]>', $text);
$text = preg_replace('#<script[^>]*?>.*?</script>#si', '', $text);
$text = strip_tags($text, '<p>');
$excerpt_length = 80;
$words = explode(' ', $text, $excerpt_length + 1);
if (count($words)> $excerpt_length) {
array_pop($words);
array_push($words, '[...]');
$text = implode(' ', $words);
}
}
return $text;
}
and called it in the template as
<?php wpden_excerpt('text'); ?>
But it's not working. What was wrong and how do I fix it?
UPDATE
I still need help!!! I tried many different combo of custom excerpt and limiting the excerpt to one paragraph and I wasn't able to do so... Please help!!

Answer 1

Thanks to my brother's help, I was able to edit the code to show two paragraphs for a custom excerpt:
// Create the Custom Excerpts callback
function wpden_excerpt()
{
global $post;
$output = get_the_content();
$wanted_number_of_paragraph = 2;
$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;
}
and call it in my template file as
<?php wpden_excerpt(); ?>
