我遇到了一个严重的问题,将我的'select'语句转换为可以与zend paginator一起使用的东西...有人可以解决它,因为我没有运气......
这是我的问题:
$query = "SELECT
user_id, name, gender, city, province, country, image_id, one_liner, self_description, reputation
FROM
users
WHERE
(
(69.1 * (latitude - " . $user->latitude . ")) *
(69.1 * (latitude - " . $user->latitude . "))
) + (
(69.1 * (longitude - " . $user->longitude . ") * COS(" . $user->latitude . " / 57.3)) *
(69.1 * (longitude - " . $user->longitude . ") * COS(" . $user->latitude . " / 57.3))
) < " . pow($radius, 2) . "
ORDER BY
(
(69.1 * (latitude - " . $user->latitude . ")) *
(69.1 * (latitude - " . $user->latitude . "))
) + (
(69.1 * (longitude - " . $user->longitude . ") * COS(" . $user->latitude . " / 57.3)) *
(69.1 * (longitude - " . $user->longitude . ") * COS(" . $user->latitude . " / 57.3))
这是我到目前为止所做的:
$select = $db->select();
$select->from(
array('users'),
array(
'user_id',
'name',
'gender',
'city',
'province',
'country',
'image_id',
'one_liner',
'self_description',
'reputation'
)
);
$select->where("(69.1 * (latitude - " . $user->latitude . ")) * (69.1 * (latitude - " . $user->latitude . "))) + ((69.1 * (longitude - " . $user->longitude . ") * COS(" . $user->latitude . " / 57.3)) * (69.1 * (longitude - " . $user->longitude . ") * COS(" . $user->latitude . " / 57.3))) < " . pow($radius, 2));
$select->order("(69.1 * (latitude - " . $user->latitude . ")) * (69.1 * (latitude - " . $user->latitude . "))) + ((69.1 * (longitude - " . $user->longitude . ") * COS(" . $user->latitude . " / 57.3)) * (69.1 * (longitude - " . $user->longitude . ") * COS(" . $user->latitude . " / 57.3))) ASC");

为什么你有“&lt;”在你的订单条款中?
答案 1 :(得分:1)
这与Zend_Paginator有什么关系?啊,你有查询,你不知道如何用它创建一个paginator,或者paginator不使用这个查询?
我唯一能看到的是你在where()
和order()
条款中缺少一个左括号:
$select->where("((69.1 * [...] ");
$select->order("((69.1 * [...] ");
^
因此,可能Zend_Paginator无法正常工作,因为SQL查询有错误?
当然,我必须问:你插入的变量是安全的,还是真的应该使用$db->quote($user->latitude, Zend_Db::FLOAT_TYPE)
?

假设您正在使用MVC模式,这不会起作用吗?
在你的引导程序中:
Zend_View_Helper_PaginationControl::setDefaultViewPartial('pagination.phtml');
在您的控制器中:
$page = Zend_Paginator::factory($select);
$page->setCurrentPageNumber($this->_getParam('page', 1));
$page->setItemCountPerPage($this->_getParam('par', 20));
$this->view->results= $page;
在您看来:
<?php foreach($this->results as $result) : ?>
<!-- print some $result stuff here -->
<?php endforeach;?>
<?= $this->results ?>
然后放置一个pagination.phtml示例,您可以在zend手册中找到它 -lo
