我有这个代码。问题是：它不遵守“按名称命名ASC”。关于查询，我不知道为什么。它发生在所有3个功能中。 这是代码：
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
require_once("dbconfig.php");
class location extends dbconfig {
public static $data;
function __construct() {
if (in_array('__construct', get_class_methods(get_parent_class($this)))) {
parent::__construct();
}
}
public static function getCountries() {
try {
$query = "SELECT id, name FROM countries ORDER BY name ASC";
$result = dbconfig::run($query);
if(!$result) {
throw new exception("Country not found.");
}
$res = array();
while($resultSet = mysqli_fetch_assoc($result)) {
$res[$resultSet['id']] = $resultSet['name'];
}
$data = array('status'=>'success', 'tp'=>1, 'msg'=>"Countries fetched successfully.", 'result'=>$res);
} catch (Exception $e) {
$data = array('status'=>'error', 'tp'=>0, 'msg'=>$e->getMessage());
} finally {
return $data;
}
}
public static function getStates($countryId) {
try {
$query = "SELECT id, name FROM states WHERE country_id=".$countryId." ORDER BY name ASC";
$result = dbconfig::run($query);
if(!$result) {
throw new exception("State not found.");
}
$res = array();
while($resultSet = mysqli_fetch_assoc($result)) {
$res[$resultSet['id']] = $resultSet['name'];
}
$data = array('status'=>'success', 'tp'=>1, 'msg'=>"States fetched successfully.", 'result'=>$res);
} catch (Exception $e) {
$data = array('status'=>'error', 'tp'=>0, 'msg'=>$e->getMessage());
} finally {
return $data;
}
}
public static function getCities($stateId) {
try {
$query = "SELECT id, name FROM cities WHERE state_id=".$stateId." ORDER BY name ASC";
$result = dbconfig::run($query);
if(!$result) {
throw new exception("City not found.");
}
$res = array();
while($resultSet = mysqli_fetch_assoc($result)) {
$res[$resultSet['id']] = $resultSet['name'];
}
$data = array('status'=>'success', 'tp'=>1, 'msg'=>"Cities fetched successfully.", 'result'=>$res);
} catch (Exception $e) {
$data = array('status'=>'error', 'tp'=>0, 'msg'=>$e->getMessage());
} finally {
return $data;
}
}
}
的Javascript
function ajaxCall() {
this.send = function(data, url, method, success, type) {
type = type||'json';
var successRes = function(data) {
success(data);
};
var errorRes = function(e) {
console.log(e);
alert("Error found \nError Code: "+e.status+" \nError Message: "+e.statusText);
};
$.ajax({
url: url,
type: method,
data: data,
success: successRes,
error: errorRes,
dataType: type,
timeout: 60000
});
}
}
function locationInfo() {
var rootUrl = "../PDOClasses/CountriesList/api.php";
var call = new ajaxCall();
this.getCities = function(id) {
$(".cities option:gt(0)").remove();
var url = rootUrl+'?type=getCities&stateId=' + id;
var method = "post";
var data = {};
$('.cities').find("option:eq(0)").html("Carregando..");
call.send(data, url, method, function(data) {
$('.cities').find("option:eq(0)").html("Selecione a cidade");
if(data.tp == 1){
$.each(data['result'], function(key, val) {
var option = $('<option />');
option.attr('value', key).text(val);
$('.cities').append(option);
});
$(".cities").prop("disabled",false);
}
else{
alert(data.msg);
}
});
};
this.getStates = function(id) {

$(".states").prop("disabled",false);

this.getCountries = function() {

}
$(function() {

});
和api
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
ob_start();
header("Access-Control-Allow-Origin: *");
header('Content-Type: application/json');
include_once("location.php");
$loc = new location();
try {
if(!isset($_GET['type']) || empty($_GET['type'])) {
throw new exception("Type is not set.");
}
$type = $_GET['type'];
if($type=='getCountries') {
$data = $loc->getCountries();
}
if($type=='getStates') {
if(!isset($_GET['countryId']) || empty($_GET['countryId'])) {
throw new exception("Country Id is not set.");
}
$countryId = $_GET['countryId'];
$data = $loc->getStates($countryId);
}
if($type=='getCities') {
if(!isset($_GET['stateId']) || empty($_GET['stateId'])) {
throw new exception("State Id is not set.");
}
$stateId = $_GET['stateId'];
$data = $loc->getCities($stateId);
}
} catch (Exception $e) {
$data = array('status'=>'error', 'tp'=>0, 'msg'=>$e->getMessage());
} finally {
echo json_encode($data);
}
ob_flush();
