在自定义简码中调用未定义的函数do_shortcode

Question

I'm creating a custom element for the WPBakery plugin and receiving an error when adding do_shortcode($content) .

My element is named hero.php and its function is as follows (in WPBakery):

• User selects hero module from option ( hero_html() ).
• User can then (within the hero module) chose to add a slide ( hero_content_html() ).

Visual:

A var_dump($content) spits out the fields and values, which are correct, but unsure why do_shortcode is undefined?

Below is where the function is called:

 <?php public function hero_html( $atts, $content = null) { $output = $el_class = extract( shortcode_atts( array( 'el_class' => '', 'css' => '', ), $atts ) ); static $i = 0; $output = '<div id="slickslider-'.$i++.'">'.do_shortcode($content).'</div>'; return $output; } public function hero_content_html( $atts, $content = null ) { $output = $title = extract( shortcode_atts( array( 'title' => '', ), $atts ) ); $output .= ' <!-- Slide --> <div class="heroSlider">'; $output .= ' <div class="container"> <div class="row"> <div class="col-10"> '(!empty($title) ? '<h1>' . $title . '</h1>' : "" );' </div> </div> </div> </div> <!-- Slide --> '; return $output; } } ?>

Please check for the file wp-load.php whether it's being loaded before this page or not. For running do_shortcode() ,wp-load.php is required.
