Zen-cart扩展国家表管理_zencart教程_php教程

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。

Zen-cart国家表管理扩展

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。
