来自nameValuePairs的值未成功传递到数据库

Question

I am using nameValuePairs in passing my datas to the database. The values inside it are from a map. I put it into a string then put the string to the nameValuePairs. My php seems to work fine. My goal here is to update my table containing counts using the where inside my SQL statement.

<?php

$conn = mysqli_connect("localhost", "root", "", "nearbyme");
$namelocation = $_GET['namelocation'];
$count = $_GET['count'];

$sql = "UPDATE place SET count= '$count' WHERE namelocation='$namelocation' ";
$result = mysqli_query($conn, $sql);

if($result){
echo "Updated!";
}else{
echo "failed"; 
}
?>

This is my Activity in passing the datas using nameValuePairs.

MapsActivity.java

Answer 1

in your php script change

$namelocation = $_GET['namelocation'];
$count = $_GET['count'];

to

$namelocation = $_REQUEST['namelocation'];
$count = $_REQUEST['count'];
