예!) (mysqli_query :android에서보기 목록을 사용하여 mysql 데이터베이스 및 디스플레이에서 여러 테이블에 가입하는 방법
경고 : 나는
Unfortunatey 내 PHP를위한이 오류를 받고 있어요 ... MySQL 데이터베이스에 여러 테이블에서 데이터를 표시하고 안드로이드에서보기 목록을 사용하여 데이터를 표시하는 방법을 알고 싶어요 C : \ xampp \ htdocs \ elba \ TRYreportclockIN.php on line 11
경고 : mysqli_fetch_array()는 매개 변수 1이 mysqli_result가 될 것으로 예상하고, 부울은 주어진다. C : \ xampp \ htdocs \ elba \ TRYreportclockIN.php 14 행 { "result": []}
앉아서 uation 내가 가진 두 개의 테이블 :
-attendancedetail테이블 attendancedetail에서
-attendancedetailclockout 나는이 테이블에서 같은 모든 데이터를 원하는 :
이
-atdClockIn
을 -atdId-empId
내가 데이터 만 원하는 attendancedetailclockout 테이블에서
-empUsername :<?php
$empUsername= $_GET['empUsername'];
require_once('connectDB.php');
$con = new mysqli($server, $user, $pass, $db);
$sql = "SELECT i.*, o.atdClockOut FROM attendancedetail i join attendancedetailclockout o on i.empUsername=o.empUsername WHERE empUsername='$empUsername' ";
$res=mysqli_query($con,$sql);
$result=array();
while($row=mysqli_fetch_array($res))
{
array_push($result,array
('atdId'=>$row[0],
'atdClockIn'=>$row[1],
'empId'=>$row[2],
'empUsername'=>$row[3],
'atdClockOut'=>$row[1]));
}
echo json_encode(array("result"=>$result));
mysqli_close($con);
