Different arrays for different post types

How guys I’m using a theme called X-Theme and I want to sort by custom field by post type.

I have posts, portfolio and events posts type.
My theme use this function to sort recent posts:

<?php

// Recent Posts
// =============================================================================

function x_shortcode_recent_posts( $atts ) {
  extract( shortcode_atts( array(
    'id'          => '',
    'class'       => '',
    'style'       => '',
    'type'        => 'post',
    'count'       => '',
    'category'    => '',
    'offset'      => '',
    'orientation' => '',
    'no_image'    => '',
    'fade'        => ''
  ), $atts, 'x_recent_posts' ) );

  $allowed_post_types = apply_filters( 'cs_recent_posts_post_types', array( 'post' => 'post' ) );
  $type = ( isset( $allowed_post_types[$type] ) ) ? $allowed_post_types[$type] : 'post';

  $id            = ( $id          != ''          ) ? 'id="' . esc_attr( $id ) . '"' : '';
  $class         = ( $class       != ''          ) ? 'x-recent-posts cf ' . esc_attr( $class ) : 'x-recent-posts cf';
  $style         = ( $style       != ''          ) ? 'style="' . $style . '"' : '';
  $count         = ( $count       != ''          ) ? $count : 3;
  $category      = ( $category    != ''          ) ? $category : '';
  $category_type = ( $type        == 'post'      ) ? 'category_name' : 'portfolio-category';
  $offset        = ( $offset      != ''          ) ? $offset : 0;
  $orientation   = ( $orientation != ''          ) ? ' ' . $orientation : ' horizontal';
  $no_image      = ( $no_image    == 'true'      ) ? $no_image : '';
  $fade          = ( $fade        == 'true'      ) ? $fade : 'false';

  $js_params = array(
    'fade' => ( $fade == 'true' )
  );

  $data = cs_generate_data_attributes( 'recent_posts', $js_params );

  $output = "<div {$id} class=\"{$class}{$orientation}\" {$style} {$data} data-fade=\"{$fade}\" >";

    $q = new WP_Query( array(
      'orderby'          => 'date',
      'post_type'        => "{$type}",
      'posts_per_page'   => "{$count}",
      'offset'           => "{$offset}",
      "{$category_type}" => "{$category}"
    ) );

    if ( $q->have_posts() ) : while ( $q->have_posts() ) : $q->the_post();

      if ( $no_image == 'true' ) {
        $image_output       = '';
        $image_output_class = 'no-image';
      } else {
        $image              = wp_get_attachment_image_src( get_post_thumbnail_id(), 'entry-cropped' );
        $bg_image           = ( $image[0] != '' ) ? ' style="background-image: url(' . $image[0] . ');"' : '';
        $image_output       = '<div class="x-recent-posts-img"' . $bg_image . '></div>';
        $image_output_class = 'with-image';
      }

      $output .= '<a class="x-recent-post' . $count . ' ' . $image_output_class . '" href="' . get_permalink( get_the_ID() ) . '" title="' . esc_attr( sprintf( __( 'Permalink to: "%s"', csl18n() ), the_title_attribute( 'echo=0' ) ) ) . '">'
                 . '<article id="post-' . get_the_ID() . '" class="' . implode( ' ', get_post_class() ) . '">'
                   . '<div class="entry-wrap">'
                     . $image_output
                     . '<div class="x-recent-posts-content">'
                       . '<h3 class="h-recent-posts">' . get_the_title() . '</h3>'
                       . '<span class="x-recent-posts-date">' . get_the_date() . '</span>'
                     . '</div>'
                   . '</div>'
                 . '</article>'
               . '</a>';

    endwhile; endif; wp_reset_postdata();

  $output .= '</div>';

  return $output;
}

add_shortcode( 'x_recent_posts', 'x_shortcode_recent_posts' );

I did change it to this:

function x_shortcode_recent_posts_override( $atts ) {
  extract( shortcode_atts( array(
    'id'          => '',
    'class'       => '',
    'style'       => '',
    'type'        => 'post',
    'count'       => '',
    'category'    => '',
    'offset'      => '',
    'orientation' => '',
    'no_image'    => '',
    'fade'        => '',
     'enable_excerpt' => ''
  ), $atts, 'x_recent_posts' ) );

  $allowed_post_types = apply_filters( 'cs_recent_posts_post_types', array( 'post' => 'post', 'event' => 'event' ) );
  $type = ( isset( $allowed_post_types[$type] ) ) ? $allowed_post_types[$type] : 'post';

  $id            = ( $id          != ''          ) ? 'id="' . esc_attr( $id ) . '"' : '';
  $class         = ( $class       != ''          ) ? 'x-recent-posts cf ' . esc_attr( $class ) : 'x-recent-posts cf';
  $style         = ( $style       != ''          ) ? 'style="' . $style . '"' : '';
  $count         = ( $count       != ''          ) ? $count : 3;
  $category      = ( $category    != ''          ) ? $category : '';

  if ( $type == 'post' ) {
  $category_type = 'category_name';
} else if ( $type == 'event' ) {
  $category_type = 'category';
} else {
  $category_type = 'portfolio-category';
}

  $offset        = ( $offset      != ''          ) ? $offset : 0;
  $orientation   = ( $orientation != ''          ) ? ' ' . $orientation : ' horizontal';
  $no_image      = ( $no_image    == 'true'      ) ? $no_image : '';
  $fade          = ( $fade        == 'true'      ) ? $fade : 'false';
  $enable_excerpt = ( $enable_excerpt == 'true'      ) ? true : false;

  $js_params = array(
    'fade' => ( $fade == 'true' )
  );

  $data = cs_generate_data_attributes( 'recent_posts', $js_params );

  $output = "<div {$id} class=\"{$class}{$orientation}\" {$style} {$data} data-fade=\"{$fade}\" >";

   $q = new WP_Query( array(
      'orderby'          => 'date',
      'post_type'        => "{$type}",
      'posts_per_page'   => "{$count}",
      'offset'           => "{$offset}",
      "{$category_type}" => "{$category}",
      ''
    ) );

    if ( $q->have_posts() ) : while ( $q->have_posts() ) : $q->the_post();

      if ( $no_image == 'true' ) {
        $image_output       = '';
        $image_output_class = 'no-image';
      } else {
        $image              = wp_get_attachment_image_src( get_post_thumbnail_id(), 'entry-cropped' );
        $bg_image           = ( $image[0] != '' ) ? ' style="background-image: url(' . $image[0] . ');"' : '';
        $image_output       = '<div class="x-recent-posts-img"' . $bg_image . '></div>';
        $image_output_class = 'with-image';
      }

      $output .= '<a class="x-recent-post' . $count . ' ' . $image_output_class . '" href="' . get_permalink( get_the_ID() ) . '" title="' . esc_attr( sprintf( __( 'Permalink to: "%s"', csl18n() ), the_title_attribute( 'echo=0' ) ) ) . '">'
                 . '<article id="post-' . get_the_ID() . '" class="' . implode( ' ', get_post_class() ) . '">'
                   . '<div class="entry-wrap">'
                     . $image_output
                     . '<div class="x-recent-posts-content">'
                       . '<h3 class="h-recent-posts">' . get_the_title() . '</h3>'
                       . '<span class="x-recent-posts-date">' . get_the_date() . '</span>'
                       . ( $enable_excerpt ? '<span class="x-recent-posts-excerpt">' . strip_tags( get_the_excerpt() ) . '</span>' : '' )
                     . '</div>'
                   . '</div>'
                 . '</article>'
               . '</a>';

    endwhile; endif; wp_reset_postdata();

  $output .= '</div>';

  return $output;
}
add_action('init', 'x_overwrite_shortcode');
function x_overwrite_shortcode() {
  remove_shortcode( 'x_recent_posts' );
  add_shortcode( 'x_recent_posts', 'x_shortcode_recent_posts_override' );
}

function add_event_type( $types ) {
	$types['event'] = 'event';
	return $types;
}
add_filter( 'cs_recent_posts_post_types', add_event_type );

Like this I added the post type EVENT.

Now I want to sort by custom field JUST post type EVENTS.

Something like:

$args = array(
           'post_type' => 'event',
           'posts_per_page'   => "{$count}",
           'meta_key' => 'wpcf-event_date_start', //name of custom field
           'orderby' => 'meta_value_num',
           'order' => 'ASC'
        );

I suppose now I have to make 1 array per post type am I wrong?

I suppose I need to change something here:

if ( $type == 'post' ) {
  $category_type = 'category_name';
} else if ( $type == 'event' ) {
  $category_type = 'category';
} else {
  $category_type = 'portfolio-category';
}

Sorry my php skills are really basic.
