two or three post information under image

[Eike-L]

Hello,
how can I show two or three post information under image, eg. Tags, date and number of comments?
The responsible files for it found. What do I need to change the files?

content.php

<?php
	if(get_theme_mod('portfolio_post_show_tags', '1') == '1') {
		$tag_list = get_the_tag_list('<ul class="tags-links"><li>',', </li><li>','</li></ul>');
   		if ($tag_list) {
    	echo $tag_list;
    	}
	}
?>

customizer/sanitization.php

function portfolio_meta_types($value) {
	$types = array(
		'tags',
		'categories',
		'date',
		'title'
	);
	
	if(in_array($value, $types)) {
		return $value;
	}
	
	return null;
}

theme-customizer.php

	$wp_customize->add_setting(
	    'portfolio_meta_type',
	    array(
	        'default'   => 'tags',
	        'capability' => 'edit_theme_options',
	        'sanitize_callback' => 'portfolio_meta_types'
	    )
	);

    $wp_customize->add_control(
        'portfolio_meta_type',
        array(
            'section'  => 'static_front_page',
            'label'    => __('Post information under image', 'portfolio'),
            'type'     => 'select',
            'choices'  => array(
            	'tags' => __('Post tags', 'portfolio'),
            	'categories' => __('Post categories', 'portfolio'),
            	'date' => __('Post date', 'portfolio'),
            	'title' => __('Post title', 'portfolio')
            )
       	 )
    );
