httpPost Android的PHP

Question

我發送來自Android客戶端用戶名的PHP服務器，但它似乎POST不工作，用戶名不是由服務器讀取...

的Android代碼

PHP代碼

<?php 
if(isset($_POST) ){ 
print_r($_POST); 




//connexion base 
$link = mysql_connect("localhost","root","") or die ('ERREUR '.mysql_error()) ; 
$bd_selected=mysql_select_db("mydb",$link) or die ('ERREUR1 '.mysql_error()); 

$req1=" SELECT * FROM user WHERE (login= '$log')"; 

$sql=mysql_query($req); 
$data = mysql_num_rows($sql);// affiche le nombre de ligne satisfaisant condition 
echo $req; 



mysql_close($link); 
} 
?> 

的錯誤是$日誌= $ _ POST [ '登錄']未定義

Ť RY這個代碼 你只是在你的代碼留下一個單行休息，一切都很好

<?php  
    $log=$_POST['log']; // Here define log value in $log variable 
    if(isset($_POST) ) 
    { 
    print_r($_POST); 

//connexion base 

    $link = mysql_connect("localhost","root","") or die ('ERREUR '.mysql_error()) ; 
    $bd_selected=mysql_select_db("mydb",$link) or die ('ERREUR1 '.mysql_error()); 

    $req1=" SELECT * FROM user WHERE (login= '$log')"; 

    $sql=mysql_query($req1); 
    $data = mysql_num_rows($sql);// affiche le nombre de ligne satisfaisant condition 
    echo $req1;  
    mysql_close($link); 
    } 
    ?>
