vc_map_get_attributes

Filters the merged shortcode attributes after combining user-supplied values with registered defaults. This runs after shortcode_atts() processes the values, allowing final modification of all element attributes.

Parameters

Parameter	Type	Description
$atts	array	The merged array of shortcode attributes (defaults combined with user-supplied values).
$tag	string	The shortcode tag name (e.g., vc_column_text).

Usage

<?php
add_filter( 'vc_map_get_attributes', 'my_modify_element_attributes', 10, 2 );

function my_modify_element_attributes( $atts, $tag ) {
    // Force a specific CSS class for all vc_column_text elements
    if ( 'vc_column_text' === $tag ) {
        $atts['el_class'] = trim( ( $atts['el_class'] ?? '' ) . ' my-custom-class' );
    }
    return $atts;
}
