И мои PHP файлы
json_res.php
<?php
include "connect.php";
$result=mysql_query("SELECT* FROM emp");
while($row=mysql_fetch_assoc($result)){
$output[]=$row;
}
print(json_encode($output));
mysql_close();
?>
и json_req.php
<?php
$json = file_get_contents('php://input');
$obj = json_decode($json);
include "connect.php";
mysql_query("INSERT INTO emp VALUES ('','".$obj->{'name'}."', '".$obj->{'comments'}."')");
mysql_close($con);
?>
Вы хотите отправить изображение с android и сохранить его в базе данных mysql? – GoCrazy
@Vino .. да, я хочу выбрать изображение из android, а затем отправить его через json и сохранить его в базе данных mysql. Я знаю, что это процесс, но не знаю, как реализовать в моем коде выше. – Brett
