How to apply excerpt inside my XML data on WordPress - php

Question

I'm pulling out the data from my CRM to my WordPress site using a XML.
It worked actually, but I want to add some functions like read more with the my XML data {Web_Remarks[1]} it contains a long description.
Then I tried to add conditions from from my function.php
like excerpt and edit my descriptions code.
For my functions.php I add
<?php
// Customize excerpt for description word count length
function custom_excerpt_length(){
return 25;
}
add_filter('excerpt_length','custom_excerpt_length');
?>
And for my description.php I change my <?php the_content();?> to
<?php if ($post->post_excerpt) { ?>
<p>
<?php echo get_the_excerpt(); ?>
Read More»
</p>
<?php }else{
the_content();
}
?>
I expect the output should be "3Bed room with laundry ro..Read More..."
but what I have now is
"3Bed room with laundry room and sea view with 2 car parkings only for 3.06M!
-Bright
-Spacious
-Sea/Palm view
-Balconies
-Higher floor

Answer 1

Try,
<?php
$excerpt = get_the_excerpt();
if( !empty($excerpt) ) { ?>
<p>
<?php echo $excerpt; ?>
Read More»
</p>
<?php
} else {
the_content();
}
Or this will be a another method you can use:
<?php
// Add this code in functions.php file
function wp_get_custom_excerpt( $limit = '25' ) {
global $post;
$content = get_the_excerpt();
if( empty($content) ) {
$content = strip_shortcodes( $post->post_content );
}
$excerpt = wp_trim_words( $content, $limit, '[...]' );
return $excerpt;
}
// Remove your excerpt code and just echo function.
echo wp_get_custom_excerpt();
