Problem with previous_post_link and next_post_link

<?php if( ! in_category(3) ) :
previous_post_link( '<div class="nav-prev">%link</div>', 'Previous', TRUE );
next_post_link( '<div class="nav-next">%link</div>', 'Next', TRUE );
endif; ?>

Also could be useful Next post link within same category, excluding one.

@vjpo I’ll try it thanks

@vjpo it unfortunately doesn’t seem to be having any effect, any other ideas? Also the snippets I shown were based on Next post link within same category, excluding one.

I’m completely stumped with this.

@vjpo aha it does work with one category but I tried doing this

<?php if( ! in_category('335,336,334') ) :
previous_post_link( '<div class="nav-prev">%link</div>', 'Previous', TRUE );
next_post_link( '<div class="nav-next">%link</div>', 'Next', TRUE );
endif; ?>

I needed 3 categories to hide the links, I am guessing I did this wrong..

Multiple categories is an array ??
<?php if( ! in_category( array( 335, 336, 334 ) )) :
or
<?php if( ! in_category( array( 'one', 'two' ) )) :

in_category example

@vjpo thanks for the help much appreciated

this has been resolved.

You are welcome ??
