Using groups_can and groups_can_not with Visual Composer

In this case, we are going to extend the ‘vc_row’ element to apply the ‘groups_can’ and ‘groups_can_not’ Groups shortcodes.

Adjusting the Theme

By adding the following lines to your themes functions.php, this new property will show in the admin row settings popup.

vc_add_param("vc_row", array(
		"type" => "textfield",
		"group" => "Groups",
		"class" => "",
		"heading" => "groups_can",
		"param_name" => "groups_can",
		'description' => 'The capability attribute is required and is used to indicate one or more capabilities separated by comma.'
));
vc_add_param("vc_row", array(
		"type" => "textfield",
		"group" => "Groups",
		"class" => "",
		"heading" => "groups_can_not",
		"param_name" => "groups_can_not",
		'description' => 'The capability attribute is required and is used to indicate one or more capabilities separated by comma.'
));

Now the Row element has two new attributes on the ‘Groups’ tab:

Each element within Visual Composer has its own template and these templates can be overruled using your own theme templates. In this case vc_row.php.

1.- Create a new folder “vc_templates” in your theme or child-theme.

2.- Copy vc_row.php from /wp-content/plugins/js_composer/includes/templates/shortcodes/ to your newly created folder.

3.- Now we are going to change this vc_row.php, this is the code that I propose:

<?php
if ( ! defined( 'ABSPATH' ) ) {
	die( '-1' );
}

/**

 * @var $el_class
 * @var $full_width

$output .= $after_output;

echo $output;

This is the part of the code that we have changed:

// @eggemplo changes
if ( isset ( $groups_can ) && ( strlen( trim( $groups_can ) ) > 0 ) ) {
	$content = do_shortcode( '[groups_can capability="' . $groups_can . '"]' . ( $content ) . '[/groups_can]' );
}
if ( isset ( $groups_can_not ) && ( strlen( trim( $groups_can_not ) ) > 0 ) ) {
	$content = do_shortcode( '[groups_can_not capability="' . $groups_can_not . '"]' . ( $content ) . '[/groups_can_not]' );
}
// end - @eggemplo changes

I hope this can help you !!!!
