我设法创建了一个表单，用户使用会话登录，一旦用户登录，他/她就可以将数据发布到名为members的不同表中。我的问题是我无法从成员表中检索登录用户添加的数据。我是新手，我希望有人在这里帮助我弄清楚这一点。下面是我的代码
<!DOCTYPE html>
<?php
session_start();
if(!isset($_SESSION['phone'])){
header("location: login2.php");
}
else {
include ("../includes/db.php");
$sql = "select * FROM post";
$run = mysql_query($sql);
$total_post=mysql_num_rows($run);
$sql = "select * FROM gallary";
$run = mysql_query($sql);
$total_image=mysql_num_rows($run);
$sql = "select * FROM user";
$run = mysql_query($sql);
$total_user=mysql_num_rows($run);
$sql = "select * FROM course";
$run = mysql_query($sql);
$total_course=mysql_num_rows($run);
$sql = "select * FROM mails";
$run = mysql_query($sql);
$total_mails=mysql_num_rows($run);
?>

答案 0 :(得分：0)
您必须以有效条件加入表格。我不知道用户表的表结构，我想这对你有所帮助。
$query="SELECT members.user_id,members.name,members.phone,members.location,
user.username,user.phone, user.id
FROM members
LEFT JOIN user
ON members.user_id=user.id
ORDER BY members.user_id;"
