[英]Lithium Framework MySQL raw query
I am fairly new to Lithium PHP Framework but I do know how to use the basic database abstraction method. 我对Lithium PHP Framework相当陌生,但我确实知道如何使用基本的数据库抽象方法。 I am using a plugin to build menu trees and it works great, although I want to use Lithium's abstraction layer for the functions.
我正在使用一个插件来构建菜单树,并且效果很好,尽管我想对功能使用Lithium的抽象层。 I'm stuck on this:
我坚持这一点:
public function get_menuItems($menu_id) {
// retrieve the left and right value of the $root node
$result = $this->database->query("SELECT * FROM ".$this->tbl_menu_items." WHERE menu_id = '$menu_id'");
if ($this->database->num_rows($result)) {
$right = array();
$result = $this->database->query("SELECT node.title, node.type, node.class_name, node.content, node.id AS id, node.lft AS lft, node.rgt AS rgt, (COUNT(parent.title) - 1) AS depth FROM ".$this->tbl_menu_items." AS node CROSS JOIN ".$this->tbl_menu_items." AS parent WHERE node.menu_id = '$menu_id' AND parent.menu_id = '$menu_id' AND node.lft BETWEEN parent.lft AND parent.rgt GROUP BY node.id ORDER BY node.lft");
$tree = array();
while ($row = mysql_fetch_assoc($result)) {
$tree[] = $row;
}
} else {
$tree = false;
}
return $tree;
}
More so the $result
part. $result
部分更是如此。 I don't know how Lithium could handle all the "AS"'s and whatnot. 我不知道锂怎么能处理所有的“ AS”之类的东西。 I tried a few different ways to execute the query as is but no luck.
我尝试了几种不同的方式执行查询,但是没有运气。
Any help would be greatly appreciated and I hope I am explaining it well enough. 任何帮助将不胜感激,我希望我能解释得足够好。
If your php version is 5.4 you can use li3_tree
behavior . 如果您的php版本是5.4,则可以使用
li3_tree
行为 。 Take a look at it, as it is a good example on how to implement such recursive behavior. 看一下它,因为它是如何实现这种递归行为的一个很好的例子。
Also, I would strongly suggest you to take a look at "Using Models" and "Adding functionality to Lithium models" as your example code could benefit a lot. 另外,我强烈建议您看一下“使用模型”和“向锂模型添加功能”,因为您的示例代码可能会受益匪浅。
