zencart新增分类字段步骤
1.categories表新增字段related_categories、related_products
ALTER TABLE `categories` ADD `related_categories` VARCHAR( 255 ) NOT NULL , ADD `related_products` VARCHAR( 255 ) NOT NULL;
2.修改admin\categories.php
大概212行
$insert_sql_data = array(‘parent_id‘ => $current_category_id,
‘date_added‘ => ‘now()‘);
改为
$insert_sql_data = array(‘parent_id‘ => $current_category_id,
‘date_added‘ => ‘now()‘,
‘related_categories‘=>$_POST[‘related_categories‘],
‘related_products‘=>$_POST[‘related_products‘]);
大概239行
$update_sql_data = array(‘last_modified‘ => ‘now()‘);
改为
$update_sql_data = array(‘last_modified‘ => ‘now()‘,‘related_categories‘=>$_POST[‘related_categories‘],‘related_products‘=>$_POST[‘related_products‘]);
大概776行
在代码$contents[] = array(‘text‘ => ‘<br />‘ . TEXT_CATEGORIES_DESCRIPTION . $category_inputs_string);
下面一行新增
$contents[] = array(‘text‘ => ‘<br />关联分类ID（ID之间用英文半角逗号隔开）<br />‘ . zen_draw_input_field(‘related_categories‘, ‘‘, zen_set_field_length(TABLE_CATEGORIES_DESCRIPTION, ‘categories_name‘)));
$contents[] = array(‘text‘ => ‘<br />关联产品ID（ID之间用英文半角逗号隔开）<br />‘ . zen_draw_input_field(‘related_products‘, ‘‘, zen_set_field_length(TABLE_CATEGORIES_DESCRIPTION, ‘categories_name‘)));
大概834行
在代码$contents[] = array(‘text‘ => ‘<br />‘ . TEXT_CATEGORIES_DESCRIPTION . $category_inputs_string);
下面一行新增
$contents[] = array(‘text‘ => ‘<br />关联分类ID（ID之间用英文半角逗号隔开）<br />‘ . zen_draw_input_field(‘related_categories‘, zen_get_related_categories($cInfo->categories_id), zen_set_field_length(TABLE_CATEGORIES_DESCRIPTION, ‘categories_name‘)));
$contents[] = array(‘text‘ => ‘<br />关联产品ID（ID之间用英文半角逗号隔开）<br />‘ . zen_draw_input_field(‘related_products‘, zen_get_related_products($cInfo->categories_id), zen_set_field_length(TABLE_CATEGORIES_DESCRIPTION, ‘categories_name‘)));
3.admin\includes\functions\extra_functions\目录下新建文件extra_functions.php
写入以下代码：
<?php
function zen_get_related_categories($category_id) {
global $db;
$category = $db->Execute("select related_categories
from " . TABLE_CATEGORIES . "
where categories_id = ‘" . (int)$category_id . "‘");
return $category->fields[‘related_categories‘];
}
function zen_get_related_products($category_id) {
global $db;
$category = $db->Execute("select related_products
from " . TABLE_CATEGORIES . "
where categories_id = ‘" . (int)$category_id . "‘");
return $category->fields[‘related_products‘];
}
?>
