Hi, I would like to write, the total number of likes, but I don't know how I can make this to retrieve the contents of the table

PHP

<?php
try
{
$user = 'root';
$pass = '';
$PDO = new PDO('mysql:host=localhost;dbname=mike', $user, $pass);
$PDO->exec("set names utf8");
$query = "SELECT SUM(likes) as test FROM news WHERE autor=".$_SESSION['id']."";

$c_query = $PDO->prepare($query;
$c_query->execute();
$results = $c_query->fetch(PDO::FETCH_ASSOC);

    if($results)
    {
        echo "Total number of likes: ".$f_test = $results['test'];
    }
}
catch(PDOException $e)
{
echo "Error: " .$e;
}
?>

What I have tried:

with COUNT() and use multiple query

Have you tried: SELECT COUNT(column_name) FROM table_name; ?

Solution 1

This should do it.

PHP

$rCount= $PDO->query($query)->fetchColumn(); 
echo '<br/> Total number of likes: '.$rCount;

I would like get all date for logged user.

can you explain in detail with an example?

The point is that he wants to draw the total number. So if the user has two posts and two users have given them like this. Then the total number is 4. So I wanted to use $ _SESSION ['id']. Would it be better to send uploads to the user id database?

If it only list of date

foreach($db->query('SELECT YourDateColumn FROM news WHERE autor='.$_SESSION['id']) as $row) {
		echo $row['YourDateColumn'];
	}
