The question:
I know how to filter the output of the function the_permalink
– it is like this:
add_filter('the_permalink', 'my_the_permalink');
function my_the_permalink($url) {
return 'http://mysite/my-link/';
}
And it works when I use it like: <?PHP the_permalink($id); ?>
, but I wanted to change the link returned by get_permalink($id)
function. And this filter doesn’t affect the returned permalink in that case.
I was trying to catch it with:
add_filter('post_link', 'my_get_permalink', 10, 3);
function my_get_permalink($url, $post, $leavename=false) {
return 'http://mysite/my-link/';
}
But this filter isn’t fired for the get_permalink()
. So how can I alter the links returned by the get_permalink()
?
The Solutions:
Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.
Method 1
Note that post_link
filter is only for the post
post type.
For other post types these filters are available:
post_type_link
for custom post typespage_link
for pageattachment_link
for attachment
The get_permalink()
function is actually a wrapper for:
get_post_permalink()
get_attachement_link()
get_page_link()
in those cases.
Here’s a way (untested) to create a custom wpse_link
filter for all the above cases of get_permalink()
:
foreach( [ 'post', 'page', 'attachment', 'post_type' ] as $type )
{
add_filter( $type . '_link', function ( $url, $post_id, ? bool $sample = null ) use ( $type )
{
return apply_filters( 'wpse_link', $url, $post_id, $sample, $type );
}, 9999, 3 );
}
where we can now filter all cases with:
add_filter( 'wpse_link', function( $url, $post_id, $sample, $type )
{
return $url;
}, 10, 4 );
Method 2
I successfully use this statement.
add_filter('post_type_link', function ($post_link, $post, $leavename, $sample) {
if ($post->post_type == 'mycustomposttype') {
...
$post_link = 'https://my.custom.site' . $some_uri;
}
return $post_link;
}, 999, 4);
