我使用此代码并添加了我的完整代码。我找不到我所做的错误..我想在服务器中发布我的数据和图像。
public class MainActivity extends Activity {
String name, price;
private static final int SELECT_PICTURE = 1;

});
signup.setOnClickListener(new OnClickListener() {
@Override

new PostPicture().execute();
}
});
}
@Override

// dismiss the dialog once product deleted
pDialog.dismiss();
if (file_url != null) {
Toast.makeText(MainActivity.this, file_url, Toast.LENGTH_LONG)

}
}
}
}
还有我的 php 文件
$response = array();
// check for required fields
if (isset($_POST['name']) && isset($_POST['price']) && isset($_POST['description'])) {
$name = $_POST['name'];
$price = $_POST['price'];
$description = $_POST['description'];
// include db connect class
require_once __DIR__ . '/db_connect.php';
// connecting to db
$db = new DB_CONNECT();
// mysql inserting a new row
$result = mysql_query("INSERT INTO products(name, price, description) VALUES('$name', '$price', '$description')");
// check if row inserted or not
if ($result) {
// successfully inserted into database
$response["success"] = 1;
$response["message"] = "Product successfully created.";
// echoing JSON response
echo json_encode($response);
} else {
// failed to insert row
$response["success"] = 0;
$response["message"] = "Oops! An error occurred.";
// echoing JSON response
echo json_encode($response);
}
} else {
// required field is missing
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";
// echoing JSON response
echo json_encode($response);
} ?>
