I use the search result and I GET

$s = $_GET['s'];  

Which gives: "mario"

Now there is a category named Mario Bianchi under a main category called Persone

When I GET $s I need to get all posts within that category, I tried the following but I get nothing

$terms = get_terms( 'category', array(

    'name__like' => $s,

    'hide_empty' => true // Optional 

) );

if ( count($terms) > 0 ){

    echo '<ul>';

    foreach ( $terms as $term ) {

        echo '<li><a href="' . esc_url( get_term_link( $term ) ) . '" title="' . esc_attr( $term->name ) . '">' . esc_html( $term->name ) . '</a></li>';

    }

    echo '</ul>';

}

Yet I need the actual post attached, not the category itself

get_terms does just that, it get the terms for your query. What you'll want is WP_Query with a tax_query. You've already got the categories you want to return the posts for, so it shouldn't be too difficult

$terms = get_terms( array(

    'taxonomy'   => 'category',

    'name__like' => $s,

    'hide_empty' => true // Optional 

) );



$term_ids = array();



if ( ! empty( $terms ) ) {

    foreach( $terms as $term ) {

        $term_ids = $term->term_id;

    }



    $args = array(

        'post_type' => 'post',

        'tax_query' => array(

            array(

                'taxonomy' => 'category',

                'terms'    => $term_ids,

            ),

        ),

    );



    $query = new WP_Query( $args );



    if ( $query->have_posts() ) {

        echo '<ul>';

        while ( $query->have_posts() ) {

            $query->the_post();

            echo '<li><a href="' . esc_url( get_the_permalink() ) . '" title="' . get_the_title() . '">' . esc_html( get_the_title() ) . '</a></li>';

        }

        echo '</ul>';

    }

    wp_reset_postdata();



}
