Ecmall Pendant Development Example One

(Refer to related articles on the web, test reviews, the following methods test success) 1: Add the page module to be displayed on the page <div class= "left" area= "Bottom_foot" widget_type= "area" > <!--{ Widgets Page=index area=bottom_foot}--></div>2: Modify the project directory under/data/page_config/ default.index.config.php to add information about the module ( modifying a page profile directly is not a good way to do it)    ' Widgets ' =>  ... Array (     ' _widget_1000 ' =>                  Array (                  ' name ' = ' Test ',                  ' Options ' =>                              Array (                              ' ad_image_url ' = ' data/files/mall/template /200908070207084061.gif ',                              ' ad_link_url ' = ',            '                   ),                 ), ), ...　　  ' config ' =>    ...

$goods = $test _mod->getall ("select * from ecm_goods where goods_id = 1");
   return $goods;   } }   4: Building model Files under Includes/model (interacting with the database)    class Testmodel extends basemodel{      content can copy the same file as other pendants, or is empty (not tested)}   5: Create a widget.html file in a sibling directory (the template is for presentation)   <div class= "Module_common" >    Pendant Development NotesEcmall pendant development is essentially a background development of a lot of pages, respectively, to invoke the program to display these pages, to achieve the purpose of the first page content replacement, so as to reduce the follow-up development, developers only need to develop the pendant can be, as far as the location can be arbitrarily determined.     (You also need to adjust the HTML, but at least the background data does not have to do) process introduction: 1:ecmall template page Call widget page (the whole process is more complex) <!--{Widgets Page=index area=cycle_image}--> Parameters: Page: Indicates the index page area: Indicates the displayed region.   (equivalent to telling the program that the generated page was put there) 2: After the Ecmall template engine regenerates a temporary PHP file, the above code is parsed into such PHP code. <!--{Widgets Page=index area=cycle_image}--> <?php $this->display_widgets (Array (' page ' = ' index ', ' area ' = ' cycle_image ');?>   3: View the source  /** * view callback function for the next display_widgets () method [show small pendant] * * @author     garbin * @param      Array $options  * @return     void */ 　　 function Display_widgets ($options) {  $area = isset ($options [' area '])? $options [' Area ']: '; $page = Isset ($options [' page '])?　　$options [' page ']: ';　　if (! $area | |! $page) {return; } include_once (Root_path.
