Taxonomy related query not working

Question

For all of my pages I have setup a taxonomy field using the plugin Advanced Custom Fields, for which I can then select as Home category, or something else like News. I am using the default category option, not a custom taxonomy.

I have a custom post type slides_post_type where for each new slide I am selecting the relevant category, i.e. Home.

The code I am using at present to output the slides is:

<?php
$slides_category = get_field('slider_category');
$args = array(-
'post_type' => 'slides_post_type',
'tax_query' => array(
    array(
        'taxonomy' => 'category',
        'field'    => 'slug',   
        'terms'    => array( $slides_category ),
    ),
),    
);
$query = new WP_Query( $args );
$my_secondary_loop = new WP_Query( $args );
if( $my_secondary_loop->have_posts() ): while( $my_secondary_loop->have_posts() ): $my_secondary_loop->the_post(); ?>
    //Post content goes here
<?php endwhile; ?>

This should be that where my page is set to Home and my slides are set to the same category it should show those slides. However this code is not outputting anything.

Any suggestions?

Answer 1

The final code I used was:

<?php
$slides_category = get_field('slider_category');
$args = array(
    'post_type' => 'slides_post_type',
    'tax_query' => array(
        array(
            'taxonomy' => 'category',
            'field'    => 'id',
            'terms'    => array( $slides_category ),
        ),
    ),
);
$slides_loop = new WP_Query( $args );
if( $slides_loop->have_posts() ): while( $slides_loop->have_posts() ): $slides_loop->the_post(); ?>
     // Post content goes here
<?php endwhile; ?>

Use wp_reset_query() after first query, on 3th code line $args = array(- clear extra -
