PHP - Get The Id Of Current Table With Buttons In While Loop For Rating System

I've built a database based rating system, and till now everything works as expected except of one minor thing that breaks the while rating system.

When you press thumbs up or down it's only adding the vote to the LAST printed table in the while loop, it does NOT add it to the current table where the button was pressed.

This is the while loop:


<?php 
function knuffix_list ($query, $user_name, $avatar_path, $dbc) {

$data = mysqli_query ($dbc, $query) or die (mysqli_error ($dbc));

//Loop through the array of data

while ($row = mysqli_fetch_array ($data)) {

global $con_id;

$con_id = $row['con_id'];

echo "<table padding='0' margin='0' class='knuffixTable'>";

echo "<tr><td width='65px' height='64px' class='avatar_bg' rowspan='2' colpan='2'><img src='$avatar_path' alt='avatar' /></td>";

echo "<td class='knuffix_username'><strong>" . $user_name . " ___ ";

echo "</strong><br />" . $row['category'] .  " | " . date('M d, Y', strtotime($row['contributed_date'])) . "</td></tr><tr><td>";

echo "<form action='' method='post'>

<button type='submit' name='plusVote' value='like'>Y</button>

<button type='submit' name='minusVote' value='dislike'>N</button>

<input type='hidden' name='hidden_con_id' value='<?= " . $con_id . " ?>' />

</form></td><td class='votes'>Y[ - ] | N[ - ]</td></tr>";

echo "<tr><td class='knuffix_name' colspan='3'><strong>" . htmlentities($row['name']) . "</strong><br /></td></tr>";

echo "<tr><td colspan='2' class='knuffix_contribution'><pre>" . $row['contribution'] . "</pre><br /></td></tr>";

echo "</table>";

}

mysqli_close($dbc);

}

?>


The con_id is the value how I wanted to determine which table it is, when I echo $con_id out (inside the while loop) it's showcasing the numbers correctly, but it doesn't work with the buttons, the buttons simply correspond to the last printed table in the while loop. I think it's because the while loop goes through each row until it's finished and it stops.

This is the rating script:



// RATING SYSTEM

$plus_vote = $_POST['plusVote'];
$minus_vote = $_POST['minusVote'];


if ($plus_vote || $minus_vote) {

$query = "SELECT * FROM con WHERE con_id = '$con_id'";
$query = mysqli_query ($dbc, $query) or die (mysqli_error($dbc)); 
$assoc_vote = mysqli_fetch_assoc ($query);

if ($plus_vote) {

$vote_up = $assoc_vote['likes'] + 1;

$query = "UPDATE con SET likes = '$vote_up' WHERE con_id = '$con_id'";

$query_run = mysqli_query ($dbc, $query) or die (mysqli_error ($dbc)); 

mysqli_close($dbc);

echo "test " . $con_id;

} elseif ($minus_vote) {

$vote_down = $assoc_vote['dislikes'] - 1; 

$query = "UPDATE con SET dislikes = '$vote_down' WHERE con_id = '$con_id'";

$query_run = mysqli_query ($dbc, $query) or die (mysqli_error ($dbc)); 

mysqli_close($dbc);

echo "test " . $con_id;

}
}



If I would be able to make the buttons in the while loop to RECOGNIZE the correct con_id of the table the button was being pressed then the script would work as intended and it would add the vote to the correct row in the table.

How could I solve this problem, because I really have no idea?
