【问题描述】:
我是 PHP/HTML5 的新手。我找到了以下 HTML5 示例来获取设备纬度和经度。但这只是通过单击按钮显示纬度/经度的示例。
问题: 我需要的是,当用户提交表单时,我会将值插入 MySQL。 此时,我想获取设备纬度/经度并将其分配为变量,以便我可以使用变量同时插入 MySQL。我的数据库中已准备好经纬度表。
请给我一些提示、指导和提示,以实现我所需要的。帮助将不胜感激。谢谢。
代码:
<!DOCTYPE html>
<html>
<body>
<p id="demo">Click the button to get your coordinates:</p>
<button onclick="getLocation()">Try It</button>
<script>
var x=document.getElementById("demo");
function getLocation()
{
if (navigator.geolocation)
{
navigator.geolocation.getCurrentPosition(showPosition);
}
else{x.innerHTML="Geolocation is not supported by this browser.";}
}
function showPosition(position)
{
x.innerHTML="Latitude: " + position.coords.latitude +
"<br>Longitude: " + position.coords.longitude;
}
</script>
</body>
</html>
形式:
<form id="form1" name="form1" method="post" action="';
echo $_SERVER['PHP_SELF'];
echo '">
<p>Please complete this form and I will contact you as soon as possible. Thank you.</p>
<p>
<label for="name">Your Name</label>
<input type="text" name="name" id="name" />
<label for="phone">Contact Number</label>
<input type="text" name="phone" id="phone" />
<label for="message">Message to Owner</label>
<textarea name="message" id="message" cols="45" rows="5"></textarea>
<input type="submit" name="submit" id="submit" value="Submit Info" />
</p>
</form>
