( flagged: shortcode and PHP Code )

global $product;
echo “<h2 style=’color:#929292′ align=center >” . $product->get_name() .”</h2>”;

now when save (and any time save ) the product page get this error (also the product save the snippet and in frontend work ) :

Fatal error: Uncaught Error: Call to a member function get_name() on null in /home/too5948/public_html/website.com/wp-content/plugins/post-snippets/src/PostSnippets/Shortcode.php(104) : eval()’d code:2 Stack trace: #0 /home/too5948/public_html/website.com/wp-content/plugins/post-snippets/src/PostSnippets/Shortcode.php(104): eval() #1 /home/too5948/public_html/website.com/wp-content/plugins/post-snippets/src/PostSnippets/Shortcode.php(72): PostSnippets\Shortcode::phpEval(‘global $product…’) #2 /home/too5948/public_html/website.com/wp-includes/shortcodes.php(343): PostSnippets\Shortcode->PostSnippets\{closure}(”, ”, ‘product-name’) #3 [internal function]: do_shortcode_tag(Array) #4 /home/too5948/public_html/website.com/wp-includes/shortcodes.php(218): preg_replace_callback(‘/\\[(\\[?)(carous…’, ‘do_shortcode_ta…’, ‘[vc_row full_wi…’) #5 /home/too5948/public_html/website.com/wp-includes/class-wp-hook.php(287): do_shortcode(‘[vc_row full_wi…’) #6 /home/too5948 in /home/too5948/public_html/website.com/wp-content/plugins/post-snippets/src/PostSnippets/Shortcode.php(104) : eval()’d code on line 2
