02 七 10 Can I turn off the left or right hand columns for some pages only?

Yes, you can. Firstly, if you don’t already have one, create an over-ride file for tpl_main_page.php in your includes/templates/YOUR_TEMPLATE/common directory.

There is enormous scope within this one module to create turn the left and right hand columns on and off according to which page or category is to be displayed. Open it up and you will see a large comment at the top explaining some of them. Here are a few examples to help illustrate that …

If you wished to turn off the left hand column for the “contact us” and “terms & conditions” pages, find the following block of code

if (in_array($current_page_base,explode(",",'list_pages_to_skip_all_right_sideboxes_on_here,separated_by_commas,and_no_spaces')) ) {
$flag_disable_right = true;
}


and edit it to read


if (in_array($current_page_base,explode(",",'contact_us,conditions')) ) {
$flag_disable_left = true;
}


If you wished to disable both columns in category listings either add or edit the above block to read


if (in_array($cPath,explode(",",'3,8')) ) {
$flag_disable_right = true;
$flag_disable_left = true;
}

To disable the right column for a series of EZ-Pages

if (in_array($ezpage_id,explode(",",'2,5'))) {
$flag_disable_right = true;
}

Or, you can use the settings in Admin->Configuration->EZ-Pages Settings:
For example:
EZ-Pages Pages to disable left-column
EZ-Pages “pages” on which to NOT display the normal “left” column (of sideboxes) for your site.
Simply list page ID numbers separated by commas with no spaces.
Page ID numbers can be obtained from the EZ-Pages screen under Admin->Tools.
ie: 21
or leave blank.

02 七 10 显示不同的 sideboxes 为 EZ-Pages

To do this you will need to edit the sidebox module for each of the sideboxes whose behavior you wish to change. The exact change will depend upon what exactly you wish to do and whether those sideboxes should appear on other pages. Let’s assume that your objective is to selectively suppress the display of sideboxes on some EZ-Pages.

You can find your sidebox modules in the directory includes/modules/sideboxes/. Towards the bottom of each is a block of code similar to this one

require($template->get_template_dir('tpl_order_history.php',DIR_WS_TEMPLATE, $current_page_base,'sideboxes'). '/tpl_order_history.php');
$title = BOX_HEADING_CUSTOMER_ORDERS;
$title_link = false;
require($template->get_template_dir($column_box_default, DIR_WS_TEMPLATE, $current_page_base,'common') . '/' . $column_box_default);

You will need to wrap this in a conditional statement such as
if (!isset($ezpage_id) || !in_array($ezpage_id,explode(",",'2,5'))) {
require($template->get_template_dir('tpl_order_history.php',DIR_WS_TEMPLATE, $current_page_base,'sideboxes'). '/tpl_order_history.php');
$title = BOX_HEADING_CUSTOMER_ORDERS;
$title_link = false;
require($template->get_template_dir($column_box_default, DIR_WS_TEMPLATE, $current_page_base,'common') . '/' . $column_box_default);
}

This condition means that the template to display the sidebox will be called whenever the page is not an EZ-Page or, if it is an EZ-Page, it does not have ID 2 or 5. You can find the IDs of your EZ-Pages by going to Admin > Tools > EZ-Pages where the ID for each page is displayed in the first column.

Finally, and importantly, don’t forget to save your result in an over-ride file.
