Just copy below Function and Add a Function in your Divi child theme function.php file.
<?php
add_filter( 'wpseo_metadesc', 'sm_divi_builder_content_wpseo_metadesc', 10, 1 );
function sm_divi_builder_content_wpseo_metadesc( $desc ) {
// Get $post if you're inside a function
global $post;
$post_type = get_post_type( $post );
if ($post_type == "page") {
//get_meta_description
$desc = get_post_meta($post->ID, '_yoast_wpseo_metadesc', true);
if($desc=="")
{
if ( has_excerpt( $post->ID ) ) {
// This post has excerpt
$desc = $post->post_excerpt;
} else {
// This post has no excerpt
$desc = trim(strip_tags(preg_replace('/\[\/?et_pb.*?\]/', '', $post->post_content)));
$desc = substr($desc,0,155);
}
}
}
return $desc;
}
?>
1. Thank you!
2. It also works on Divi builder posts by changing ($post_type == “page”)
into ($post_type == “page” || $post_type == “post”)
Update – we just had to remove this fix because the excerpt was being forced even when a custom description had been written. Divi must have corrected the problem…
