Array wordpress php - php

Question

I want to create a portfolio in wordpress.
It is working properly but I would like to see the categories of the portfolio in h3 under the h2 title.
Other question.
Now the link will only work on the title h2, I wish it were all over the caption as link.
any advice on the code are welcome! Thank you so much
<?php
$args = array( 'post_type' => 'portfolio', 'posts_per_page' => -1 );
$loop = new WP_Query( $args );
$terms = get_the_terms( $post->ID, 'portfolio-categories' );
if ( $terms && ! is_wp_error( $terms ) ) :
$links = array();
foreach ( $terms as $term ) {
$links[] = $term->name;
}
$tax_links = join( " ", str_replace(' ', '-', $links));
$tax = strtolower($tax_links);
else :
$tax = '';
endif;
while ( $loop->have_posts() ) : $loop->the_post();
echo '<div class="row-masonry">';
echo '<div class="item">';
echo '<div class="well portfolio-item no-gutter">';
echo '<div class="thumbnail no-gutter">'. get_the_post_thumbnail() .'</div>';
echo '<div class="caption">';
echo '<div class="vertical-align">';
$link = get_the_permalink();
echo "<a href=$link>";
echo '<h2>'. get_the_title() .'</h2>';
I want to see here the portfolio image category in h3
echo "</a>";
echo '</div>'; /*close caption*/
echo '</div>'; /*close caption*/
echo '</div>';
echo '</div>';
endwhile;
echo '</div>';
echo '</div>';
echo '</div>';
?>
</div><!-- #page -->

This should work for you. You can google how to get the category for a post. It will yield your answer - but this will work.
<?php
$args = array( 'post_type' => 'portfolio', 'posts_per_page' => -1 );
$loop = new WP_Query( $args );
$terms = get_the_terms( $post->ID, 'portfolio-categories' );
if ( $terms && ! is_wp_error( $terms ) ) :
$links = array();
foreach ( $terms as $term ) {
$links[] = $term->name;
}
$tax_links = join( " ", str_replace(' ', '-', $links));
$tax = strtolower($tax_links);
else :
$tax = '';
endif;
while ( $loop->have_posts() ) : $loop->the_post();
echo '<div class="row-masonry">';
echo '<div class="item">';
echo '<div class="well portfolio-item no-gutter">';
echo '<div class="thumbnail no-gutter">'. get_the_post_thumbnail() .'</div>';
echo '<div class="caption">';
echo '<div class="vertical-align">';
$link = get_the_permalink();
echo "<a href=$link>";
echo '<h2>'. get_the_title() .'</h2>';
// GET THE CATEGORY -- Returns an array of all categories
// $categories = get_the_category();
$categories = get_the_terms( get_the_ID(), 'portfolio-categories' ); // for custom taxnomies
// If not an empty array then show the first category set
if ( ! empty( $categories ) ) {
echo "<h3>" . esc_html( $categories[0]->name ) ."</h3>";
}
echo "</a>";
echo '</div>'; /*close caption*/
echo '</div>'; /*close caption*/
echo '</div>';
echo '</div>';
endwhile;
echo '</div>';
echo '</div>';
echo '</div>';
?>
</div><!-- #page -->
