Getting second row values from table is getting issue - php

I am trying to get the course attempt details where user attempted 2 times, so whenever I try to show 2 results its showing 2 results are same.
For example in first attempt if i failed and second attempt if i passed it showing 2 records data are passed only I don't know why it is happening like that.
Here is my code for that page:
<?php
global $DB, $USER, $CFG;
include("include/header.php");
date_default_timezone_set('Asia/Kolkata');
?>
<body>
<div style="
margin: 50px 30px 5px 0px;

Session variables from for not stored and accessible on other pages

I hope I'm not asking a question already answered, I have searched extensively on the site for an answer to my problem but can not manage to find a solution.
I have the following problem.
I have a form in which is a shopping cart, it is supposed to apply a coupon and then save those values so they can be used later on different pages.
For some reason however, these session variables are not saved.
My form looks like this:
<?php
session_start();

When I then try to access the variable $_SESSION['coupon_data'] on a different page this does not work, it is empty.
I set the variable here in this code:
if(isset($_POST['apply_coupon_btn'])){
$query_coupon = mysqli_query($conn,"SELECT * FROM `st_coupon` WHERE `coupon_code`='{$_POST['coupon_apply']}' AND `status`='1'");
$fetch_coupon = mysqli_fetch_array($query_coupon);
$message = "tmp2";
if(isset($fetch_coupon)){
$_SESSION['coupon_data'] = $fetch_coupon;
..
}
And then I call the next page here:
if(isset($_POST['checkout_btn'])){
if($_SESSION['USER_EMAIL']){
header("location: afrekenen.php");
}else{
header("location: winkelwagen.php#login-modelbox");
}
}
Even if I call the update of the cart items in this same page, the session variables disapear for some reason which I do not understand:
if(isset($_POST['update_cart']))
{
echo "update cart";
foreach($_POST['custom_qty_cart'] as $key=>$qtys){
$cart_custom[$key]['price']['qty'] = $qtys;
}
setcookie('view_cart_custom_fab', json_encode($cart_custom), time() + (86400 * 2), "/");
setcookie('custom_qty', $_POST['custom_qty'], time() + (86400 * 2), "/");
$custom_total = $custom_total*$_POST['custom_qty'];
setcookie('custom', $custom_total, time() + (86400 * 2), "/");
foreach($_POST["qty"] as $key => $qty) { //Print each item, quantity and price.
$id = $_POST["product_id"][$key];
$_SESSION["products"][$id]["fabric_qty"] = $qty;
}
header("location: winkelwagen.php");
}
I am utterly baffled and hope someone can help me out.

issue resolved, turns out there was another call to session_start in one of the includes which was creating a separate session and hence not allowing the correct globalisation.

Very heavy wordpress plugin and customization

i have a wordpress website and with customization (cache/minify/database), is really quick in frontend, and in backend, with one exception. I use a plugin where it stores and retrieves players stats, carreers, teams etc.
When saving the team's match player's statistics, it needs 5 minutes to show the page reloaded with the data.
Also when retrieving for example team's season data, it also needs a lot of time to show them.
From what i ve seen, it is related with two of my files that do all the work. tournament_match.php, and functions.php. From hosting they said that it gets all tha database and thats why it is so slow
Here is the tournament_match file
<?php

Viewing queried data from mysql database in a table

I am attempting to update the code for my web page's search function, right now it is not returning anything. I have been working with it for a little while and not getting anything out of it.
This is the HTML search code:
<form method="post" action="words_results1.php">

<td><input type="text" name="Keyword" /></td>

<td valign=top>
<table>
<tr>
<td width="33%">Day</td>
<td width="33%">Month</td>
<td width="34%">Year</td>
</tr>

</select>

This last bit is the code that forms the table, I have an assumption that the problem lies here but honestly am not sure at this point

</tr>
</tbody>
</tr>
<?php
$count = 1;
$bgc = 0;
while($row = mysql_fetch_array($sql))
{
if ($count > 100) break;
echo '<tr style="background: ';
if ($bgc==0) echo "#FFFFFF";
else echo "#CFEBFD";
$bgc == 0?$bgc=1:$bgc=0;
echo ';">';
echo "<td><a href=../../words/display_word.php?ID=$row[ID]>$row[Title]</a></td>";
echo "<td>$row[Author]</td><td>$row[Display_Date]</td><td>$row[category]</td>";
if($row[active])
{
echo "<td>YES</td>";
}
else
{
echo "<td>NO</td>";
}
echo "<td>$row[link_count]</td>";
if($row[Title] != "")
{
echo "<td><a href=words_edit.html?ID=$row[ID]>Edit</a></td></tr>";
}
else
{
echo "</tr>";
}
$count++;
}
?>

It seems,you are not collecting the value of
$Keyword=$_POST['Keyword'];
and add ,closing table tag to display the results in the table format correctly.
