从Google地方信息搜索框中获取经度和纬度 [英] Getting Latitude and Longitude from Google Places Search box
问题描述
我正在尝试获取谷歌纵横来自 Google Maps Places Searchbox 的经度.
I'm Trying to get the Latitude & Longitude from Google maps Places Searchbox.
您可以在此处找到完整的代码.
you can find the whole code here.
我对Java语言没有很深的了解,因此我看到了一些实际上无效的解决方案,我认为我可能会放错获取lat和lng的代码!因此,请帮助我弄清楚应该将解决方案实际放在哪里.
I don't have a deep knowledge to Javascript so I've seen a couple of solutions that doesn't actually work and I think I might misplace the code that gets the lat and lng! So please help me to figure out where should I actually put the solution.
我尝试过
place.geometry.location.lat()
place.geometry.location.lng()
它不起作用!
我想将这些经纬度发送给HTML元素因此,我可以将它们作为表单发送到PHP操作页面,然后发送到mysql数据库.是否有快捷方式可以帮助我将它们直接发送到mysql DB或直接发送到PHP?
I'd like to send these lat and lng to HTML element so I can send them as form to a PHP action Page and then to mysql Database.. Is there a shortcut that help me send them directly to the mysql DB or to PHP directly?
推荐答案
在没有其余代码的情况下,我只能向您展示我使用表单收集地址所做的事情.使用php 7和json_decode().有一种更有效的方法可以执行此操作,但是它对我有用.希望这会有所帮助.
Without the rest of your code, I can only show you what I have done using a form to collect an address. Using php 7 with json_decode(). There is a more efficient way to do this, but it works for me. Hope this helps.
//create string holding address to run through google geolocation API for Lat/Long
//make sure to clean your posts, I use functions from another page that cleans htmls tags, trims and removes slashes and/or runs through a reg ex to replace and/or remove unwanted entries for the particular fields type.
$address = clean_post($_POST['cust_street']).' '.clean_post($_POST['cust_city']).' '.clean_post($_POST['cust_state']).', '.clean_post($_POST['cust_zip']);
// Get JSON results from this request
$url = 'https://maps.googleapis.com/maps/api/geocode/json?address='.urlencode($address).'&sensor=false&key='.APIKEY;
$geo = file_get_contents($url);
// Convert the JSON to an array
$geo = json_decode($geo, true);
if ($geo['status'] == 'OK') {
// Get Lat & Long
$latitude = $geo['results'][0]['geometry']['location']['lat'];
$longitude = $geo['results'][0]['geometry']['location']['lng'];
}else{
$latitude = NULL;
$longitude = NULL;
$sessData['status']['type'] = 'alert alert-warning';
$sessData['status']['msg'] = 'Sorry, but it seems the address you entered is not being recognized by Google Maps API service.';
//die or exit, do something on failure
}
然后,您可以将这些变量添加到数据库的插入/更新和/或根据需要将它们回显.这个代码是通过我正在使用的applet运行的,它将一个给定的地址输入到客户表单中,然后处理该地址,获取Lat和Long,然后在成功之后,将其放入数组中,然后通过插入操作插入到我的数组中.D B.然后,我可以调用它,以便以后在地图上找到这些经纬度较高的客户.
Then you can add these variables to your DB insert/update and/or echo them out as needed. This very code is run through an applet I am working on that takes a given address entered into a customer form and then processes that address, gets Lat and Long and then upon success, places that into the array I am running through the insert into my DB. I can then call on that to locate that customers lat and long on a map at a later date.
$custData = array(
'users_id' => $usr_id,
'cust_first_name' => clean_post( $cust_first_name ),
'cust_last_name' => clean_post( $cust_last_name ),
'cust_email' => clean_email( $cust_email ),
'cust_street' => clean_post( $cust_street ),
'cust_city' => clean_post( $cust_city ),
'cust_state' => clean_post( $cust_state ),
'cust_zip' => clean_post( $cust_zip ),
'cust_phone1' => clean_phone( $cust_phone2 ),
'cust_lat' => clean_phone( $latitude ),
'cust_long' => clean_float( $longitude ),
//etc,etc,etc
);
//$cust = new User(); further up in page
//insertCust() function comes from user class stored in class.user.php
$insert = $cust->insertCust($custData);
//set status based on data insert
if($insert){
//set some session variables and store them before any header redirects.
$_SESSION['status']['type'] = 'alert alert-success';
$_SESSION['status']['msg'] = 'You have registered '.$custName.' successfully!';
}
顺便说一句,我目前正在阅读有关XSS安全性的文档,并发现它最有帮助:
Btw, I am currently going through this document on XSS security and have found it to be most helpful: XSS_Filter_Evasion_Cheat_Sheet Hope this helps.
