從android數據庫中獲取數據使用php

Question

我試圖訪問數據庫中的個人播放器，我得到的答覆{「success」：0，「message」：「必填字段丟失」}但這是錯誤的，應該輸出一個單一的球員領域。

我認爲問題是與PHP代碼，但我不確定。任何幫助非常感謝，謝謝。

PHP代碼 -

<?php 

require('db_connection.php'); 

// check for post data 
if (isset($_GET["playerid"])) { 
$playerid = $_GET['playerid']; 

// get a player from week1 table 
$result = mysql_query("SELECT *FROM week1 WHERE playerid = $playerid"); 

if (!empty($result)) { 
    // check for empty result 
    if (mysql_num_rows($result) > 0) { 

     $result = mysql_fetch_array($result); 

     $player = array(); 
     $player["playerid"] = $result["playerid"]; 
     $player["score"] = $result["score"]; 
     $player["lastholeplayed"] = $result["lastholeplayed"]; 
     $player["overall"] = $result["overall"]; 

     // success 
     $response["success"] = 1; 

     // user node 
     $response["player"] = array(); 

     array_push($response["player"], $player); 

     // echoing JSON response 
     echo json_encode($response); 
    } else { 
     // no player found 
     $response["success"] = 0; 
     $response["message"] = "No player found"; 

     // echo no users JSON 
     echo json_encode($response); 
    } 
} else { 
    // no player found 
    $response["success"] = 0; 
    $response["message"] = "No player found"; 

    // echo no users JSON 
    echo json_encode($response); 
} 
} else { 
// required field is missing 
$response["success"] = 0; 
$response["message"] = "Required field(s) is missing"; 

// echoing JSON response 
echo json_encode($response); 
} 
?>

您沒有使用 「獲取」 發佈您的數據。

，當你讓你的電話與該URL的一切可以使用$ _GET：

http://blahblah.com/somescript.php?playerid=1234 

在你的代碼中，您使用$ _GET得到它。當你張貼，像你一樣使用$ _ POST：

if (isset($_POST["playerid"])) { 
    $playerid = $_POST['playerid'];
