Hello There,
If you will follow my suggestion, we can then hide the featured video when viewing the item page so that only one video will display on the page which is the one coming from the content. You can always make a little modification to the portfolio item page to make this possible. To do that, assuming that you already have a child theme installed, please follow the following steps below:
1] Using Notepad or TextEdit or Sublime Text or any text editor, please create a new file in your local machine.
2] Insert the following code into that new file
<?php
// =============================================================================
// VIEWS/INTEGRITY/CONTENT-PORTFOLIO.PHP
// -----------------------------------------------------------------------------
// Portfolio post output for Integrity.
// =============================================================================
$archive_share = x_get_option( 'x_integrity_portfolio_archive_post_sharing_enable' );
?>
<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
<?php if ( ! x_is_portfolio_item() ) : ?>
<div class="entry-featured">
<?php x_portfolio_item_featured_content(); ?>
</div>
<?php endif; ?>
<div class="entry-wrap cf">
<?php if ( x_is_portfolio_item() ) : ?>
<div class="entry-info">
<header class="entry-header">
<h1 class="entry-title entry-title-portfolio"><?php the_title(); ?></h1>
<?php x_integrity_entry_meta(); ?>
</header>
<?php x_get_view( 'global', '_content', 'the-content' ); ?>
</div>
<div class="entry-extra">
<?php x_portfolio_item_tags(); ?>
<?php x_portfolio_item_project_link(); ?>
<?php x_portfolio_item_social(); ?>
</div>
<?php else : ?>
<header class="entry-header">
<h2 class="entry-title entry-title-portfolio">
<a href="<?php the_permalink(); ?>" title="<?php echo esc_attr( sprintf( __( 'Permalink to: "%s"', '__x__' ), the_title_attribute( 'echo=0' ) ) ); ?>"><?php x_the_alternate_title(); ?></a>
</h2>
<?php if ( $archive_share == '1' ) : ?>
<?php x_portfolio_item_social(); ?>
<?php endif; ?>
</header>
<?php endif; ?>
</div>
</article>
3] Save the file named as content-portfolio.php
4] Upload this file to your server in the child theme’s folder wp-content/themes/x-child/framework/views/integrity/
Please let us know if this works out for you.
