Zen-cart扩展国家表管理

Zen-cart中国家表的管理比较粗糙，特别是在要对应国家下拉列表进行调整时，比如把常用的国家调整到最前面，那么就需要扩展一下国家表字段了。

涉及到国家表管理的是admin/countries.php文件，需要对这个文件做一些改动：

///////////////////////

$cnt = $db->metaColumns(TABLE_COUNTRIES);

if(!isset($cnt[strtoupper(‘countries_name_cn‘)])){

$db->Execute("ALTER TABLE ".TABLE_COUNTRIES." ADD countries_name_cn VARCHAR( 64 ) NULL DEFAULT ‘‘");

}

if(!isset($cnt[strtoupper(‘order_by‘)])){

$db->Execute("ALTER TABLE ".TABLE_COUNTRIES." ADD order_by int(11) NOT NULL DEFAULT ‘0‘");

}

///////////////////////
然后就是对插入编辑时的SQL进行修改，当然接下来还有修改表单(这里忽略)。

这样可以添加中文名称和排序码，排序码添加了之后还要修改两个获取国家下拉列表的函数（前台后台分别对应一个）：

#includes/functions/functions_lookups.php

function zen_get_countries($countries_id = ‘‘, $with_iso_codes = false) {

global $db;

$countries_array = array();

if (zen_not_null($countries_id)) {

} else {

///////////////////////

$cnt = $db->metaColumns(TABLE_COUNTRIES);

if(!isset($cnt[strtoupper(‘order_by‘)])){

$db->Execute("ALTER TABLE ".TABLE_COUNTRIES." ADD order_by int(11) NOT NULL DEFAULT ‘0‘");

}

///////////////////////

$countries = "select countries_id, countries_name

from " . TABLE_COUNTRIES . "

order by order_by, countries_name";

$countries_values = $db->Execute($countries);

while (!$countries_values->EOF) {

$countries_array[] = array(‘countries_id‘ => $countries_values->fields[‘countries_id‘],

‘countries_name‘ => $countries_values->fields[‘countries_name‘]);

$countries_values->MoveNext();

}

return $countries_array;

}

#admin/includes/functions/general.php

function zen_get_countries($default = ‘‘) {

global $db;

$countries_array = array();

if ($default) {

$countries_array[] = array(‘id‘ => ‘‘,

‘text‘ => $default);

}

///////////////////////

$cnt = $db->metaColumns(TABLE_COUNTRIES);

if(!isset($cnt[strtoupper(‘countries_name_cn‘)])){

$db->Execute("ALTER TABLE ".TABLE_COUNTRIES." ADD countries_name_cn VARCHAR( 64 ) NULL DEFAULT ‘‘");

}

if(!isset($cnt[strtoupper(‘order_by‘)])){

$db->Execute("ALTER TABLE ".TABLE_COUNTRIES." ADD order_by int(11) NOT NULL DEFAULT ‘0‘");

}

///////////////////////

$countries = $db->Execute("select countries_id, countries_name,countries_name_cn

from " . TABLE_COUNTRIES . "

order by order_by, countries_name");

while (!$countries->EOF) {

$countries_array[] = array(‘id‘ => $countries->fields[‘countries_id‘],

‘text‘ => $countries->fields[‘countries_name‘]." - ".$countries->fields[‘countries_name_cn‘]);

$countries->MoveNext();

}

return $countries_array;

}

函数中加入了判断对应字段是否存在的逻辑，防止出错。
