vc_gitem_template_attribute_{name}

Dynamic filter that allows modification of a specific grid item template attribute value. The {name} part is the attribute name being requested (e.g., a post field like post_title, post_date, or a custom attribute like acf_value, woocommerce_product_price_value).

Parameters

Parameter	Type	Description
$value	mixed	The attribute value. For standard post fields, this is the value of $post->{name}. For custom attributes, this is the processed value from the attribute callback.
$data	array	A context array containing post (the WP_Post object) and data (additional attribute data string).

Usage

// Filter the post_title attribute in grid items
add_filter( 'vc_gitem_template_attribute_post_title', 'wpb_modify_gitem_post_title', 10, 2 );

function wpb_modify_gitem_post_title( $value, $data ) {
    // Truncate long titles in grid items
    if ( strlen( $value ) > 50 ) {
        $value = substr( $value, 0, 50 ) . '...';
    }
    return $value;
}

// Filter a custom attribute (e.g., ACF value)
add_filter( 'vc_gitem_template_attribute_acf_value', 'wpb_modify_gitem_acf_value' );

function wpb_modify_gitem_acf_value( $value ) {
    return wp_kses_post( $value );
}
