two or more next buttons with different settings

If you are talking about the num_results parameter, yes that was added to the plugin some time ago:

<?php next_post_link_plus( array(
'order_by' => 'post_title',
'format' => '%link (category %category)',
'link' => 'Next',
'before' => '<h4>Next posts</h4><ul>',
'after' => '</ul>',
'in_same_cat' => true,
'num_results' => 3
) );?>

hi, i didnt mean “num_results” i mean actually different next buttons on the same page, eg.

next ‘in_same_cat’ = ‘abc’ | next ‘in_cats’ => ‘123’ | next ‘in_same_tax’ => ‘xyz’

If that’s what you want you can do it by calling the function three times in a row with different parameters.

<?php next_post_link_plus( array(
'format' => '%link (category %category)',
'link' => 'Next',
'in_same_cat' => 'abc'
) );?> |
<?php next_post_link_plus( array(
'format' => '%link (category %category)',
'link' => 'Next',
'in_cats' => '123'
) );?> |
<?php next_post_link_plus( array(
'format' => '%link (category %category)',
'link' => 'Next',
'in_same_tax' => 'xyz'
) );?>

but it isn’t working…

‘in_same_tax’ this gives me this error:

Warning: array_merge() [function.array-merge]: Argument #2 is not an array in /home/httpd/vhosts/naloo.net/httpdocs/wp/wp-content/plugins/ambrosite-nextprevious-post-link-plus/ambrosite-post-link-plus.php on line 114

and if i try with different categories, it always renders the same result, you can look at it here: https://naloo.net/wp/3kh/

it should get this:
next > apollo-8
logo > apollo-8
print > apparence
digital > bimi
but all three next buttons go to apollo-8

this is what the code looks like:

<?php next_post_link_plus( array('order_by' => 'post_title', 'format' => '%link', 'link' => 'next', 'in_same_cat' => 'work' ) );?>

<?php next_post_link_plus( array('order_by' => 'post_title', 'format' => '%link', 'link' => 'logo', 'in_same_cat' => 'ct-logo', 'ex_cats' => 'work', 'ex_cats_method' => 'weak' ) );?>

<?php next_post_link_plus( array('order_by' => 'post_title', 'format' => '%link', 'link' => 'print', 'in_same_cat' => 'ct-print', 'ex_cats' => 'work', 'ex_cats_method' => 'diff' ) );?>

<?php next_post_link_plus( array('order_by' => 'post_title', 'format' => '%link', 'link' => 'digital', 'in_same_cat' => 'ct-digital', 'ex_cats' => 'work', 'ex_cats_method' => 'strong' ) );?>

ahh, trial and error… i just found out! and it works, your plugin is sooo coool! thanks!

‘in_cats’ => ’22’, ‘ex_cats’ => ’11’, ‘ex_cats_method’ => ‘diff’
was the solution
