I want to filter my custom posts (pump) with a custom filter form on it’s archive page (archive-pump.php).
So, I wrote the form markup:
<form method="GET"> <label>Series</label> <?php if( $ terms = get_terms( array( 'taxonomy' => 'series', 'orderby' => 'name' ) ) ) : echo '<select name="series">'; foreach ( $ terms as $ term ) : echo '<option value="' . $ term->term_id . '">' . $ term->name . '</option>'; // ID of the category as the value of an option endforeach; echo '</select>'; endif; ?> <button type="submit">Apply filter</button> </form> And I have this to output my custom posts:
<?php if(have_posts()) : while(have_posts()) : the_post(); ?> <?php the_title( '', '', true ); ?> <?php endwhile; endif; ?> When I open my page (localhost/project/pumps) it looks fine. But when I submit my form I’m getting an 404 page.
I maybe need an seperate query to fetch all the $ _GET data. But I’m not getting to the step because of the 404 error.
What am I doing wrong? Thank you!
