Question

我是新手，目前在数据库上工作。我有一个如下模型：

/**
*
*I am editing a app which is done in version 1.3
* /app/models/get_provider.php
*/

function getListByCategory($gal_category_id,$gal_location_id,$package,$whether_list = false,$limit=999,$order_by = ""){
$conditions = array("GalProvider.status"=>1,"GalProvider.gal_category_id"=>$gal_category_id,"GalProvider.gal_location_id"=>$gal_location_id);
-------
-------
}

$package变量是一个特殊的变量，具有以下条件：

if $package = 1,starting_package will be between 15000 to 30000
if $package = 2,starting_package will be between 30001 to 45000
if $package = 3,starting_package will be between 45001 to 60000

那么我将如何在where变量中添加此$conditions条件？

这样的事情应该这样做：

<?php
function getListByCategory($gal_category_id,$gal_location_id,$package,$whether_list = false,$limit=999,$order_by = "") {
    $conditions = array(
        "GalProvider.status" => 1,
        "GalProvider.gal_category_id" => $gal_category_id,
        "GalProvider.gal_location_id" => $gal_location_id
    );

    switch ($package) {
        case 1:
            $start = 1500;
            $end = 3000;
            break;
        case 2:
            $start = 30001;
            $end = 45000;
            break;
        case 3:
            $start = 45001;
            $end = 60000;
            break;
    }

    $conditions['AND']['starting_package >='] = $start;
    $conditions['AND']['starting_package <='] = $end;

}

因此，您需要确定范围的起点和终点，然后将其添加到查询中，并在“和”键中添加，以确保它们都被考虑在内。
