PHP EEH_Template::_find_common_base_path方法代码示例

 /**
  *    locate_template
  *
  *    locate a template file by looking in the following places, in the following order:
  *        <server path up to>/wp-content/themes/<current active WordPress theme>/
  *        <assumed full absolute server path>
  *        <server path up to>/wp-content/uploads/espresso/templates/<current EE theme>/
  *        <server path up to>/wp-content/uploads/espresso/templates/
  *        <server path up to>/wp-content/plugins/<EE4 folder>/public/<current EE theme>/
  *        <server path up to>/wp-content/plugins/<EE4 folder>/core/templates/<current EE theme>/
  *        <server path up to>/wp-content/plugins/<EE4 folder>/
  *    as soon as the template is found in one of these locations, it will be returned or loaded
  *
  * 		Example:
  * 		  You are using the WordPress Twenty Sixteen theme,
  *        and you want to customize the "some-event.template.php" template,
  * 		  which is located in the "/relative/path/to/" folder relative to the main EE plugin folder.
  * 		  Assuming WP is installed on your server in the "/home/public_html/" folder,
  *        EEH_Template::locate_template() will look at the following paths in order until the template is found:
  *
  *        /home/public_html/wp-content/themes/twentysixteen/some-event.template.php
  *        /relative/path/to/some-event.template.php
  *        /home/public_html/wp-content/uploads/espresso/templates/Espresso_Arabica_2014/relative/path/to/some-event.template.php
  *        /home/public_html/wp-content/uploads/espresso/templates/relative/path/to/some-event.template.php
  *        /home/public_html/wp-content/plugins/event-espresso-core-reg/public/Espresso_Arabica_2014/relative/path/to/some-event.template.php
  *        /home/public_html/wp-content/plugins/event-espresso-core-reg/core/templates/Espresso_Arabica_2014/relative/path/to/some-event.template.php
  *        /home/public_html/wp-content/plugins/event-espresso-core-reg/relative/path/to/some-event.template.php
  *
  * 		  Had you passed an absolute path to your template that was in some other location,
  *        ie: "/absolute/path/to/some-event.template.php"
  * 		  then the search would have been :
  *
  *        /home/public_html/wp-content/themes/twentysixteen/some-event.template.php
  *        /absolute/path/to/some-event.template.php
  *
  * 		  and stopped there upon finding it in the second location
  *
  * @param array|string $templates array of template file names including extension (or just a single string)
  * @param  array   $template_args an array of arguments to be extracted for use in the template
  * @param  boolean $load          whether to pass the located template path on to the EEH_Template::display_template() method or simply return it
  * @param  boolean $return_string whether to send output immediately to screen, or capture and return as a string
  * @param boolean $check_if_custom If TRUE, this flags this method to return boolean for whether this will generate a custom template or not.
  * 				Used in places where you don't actually load the template, you just want to know if there's a custom version of it.
  * @return mixed
