DIsplaying posts only created by specific user on his own dashboard - php

Question

Displaying posts by specific user? this i saw is for ruby on rails and it couldn't help me..
I have two tables, users and posts.
If a user posts anything, it displays on his dashboard which works fine for now. But what i need is for the user to view only his posts.
Please help...
Below is my code:
server.php
<?php
// connect to database
require_once 'database.php';
// initialize variables
$note = "";
$id = 0;
$edit_state = false;
// if save button is clicked
if (isset($_POST['save'])) {
$note = addslashes($_POST['note']);
$created_at = date("Y-m-d H:i:s");
// basic first name validation
if (empty($note)) {
$error = true;
$noteError = "Field cannot be empty.";
}else {
// insert records if no error
$query = "INSERT INTO posts (note, created_at, updated_at) VALUES ('$note', '$created_at', NOW())";
mysqli_query($dbconn, $query);
$_SESSION['msg'] = "Saved";
header('location: ../home.php'); // redirect to home page after inserting
}
}
?>
and this is home.php where results are displayed
<?php
ob_start();
session_start();
error_reporting(E_ALL);
require_once 'config/database.php';
include 'config/server.php';
// if session is not set this will redirect to login page
if( !isset($_SESSION['user']) ) {
header("Location: index.php");
exit;
}
// select loggedin users detail
$res=mysqli_query($dbconn, "SELECT * FROM users WHERE Id=".$_SESSION['user']);
$userRow=mysqli_fetch_array($res);
?>
<div class="container" style="margin-top: 100px;">
<div class="row">
<div class="col-sm-6">
<div class="wrap-status100">
<form method="post" class="login100-form validate-form" action="config/server.php" autocomplete="off">

Answer 1

You need to take one more column in posts table i.e user_id. You have to store the id of user who create the Post.
While fetching the result, you can take logged in user's id. And create a query like
"Select * from posts where user_id=".$_SESSION['user'];
by this you have get all the posts created by that particular user.
Hope this helps.
Thanks.

Answer 2

You need to do this in this way:
First while adding a post you have to insert the user id of the user who is posting the post. Be sure to add a field named user_id in the posts table in db. PLease try this query:
$user_id=trim($_SESSION['user']);
$query = "INSERT INTO posts (note,user_id, created_at, updated_at) VALUES ('$note', '".$user_id."' , '$created_at', NOW())";
Now in the dashboard of the user you need to fetch the posts based on the user_id and then loop the tr in the results array:
"Select * from posts where user_id=".$_SESSION['user'];
