Then, use require ($ template-> get_template_dir ('tpl _ banner_box.php ', dir_ws_template, $ current_page_base, 'sideboxes') to load the template that displays the sidebox,
In fact, this so-called template is to generate a $ content string,
Then require ($ template-> get_template_dir ($ column_box_default, dir_ws_template, $ current_page_base, 'common'). '/'. $ column_box_default)
Use a public template that displays sidebox to print the content of $ content in $ column_box_default,

PHP echo $ box_id;?> //-> <Div linoleic = "leftboxcontainer" id = "lt ;? PHP echo str_replace ('_', '-', $ box_id);?> Quot; style = "width: <? PHP echo $ column_width;?> Quotgt; <H3 linoleic = "leftboxheading" id = "lt ;? PHP echo str_replace ('_', '-', $ box_id). 'heading';?> Quotgtlt ;? PHP echo $ title;?> Lt;/h3> the $ box_id can also form the ID of the style html
