Change table row styleclass under certain mysql conditions - php

Question

I have the following table created with a foreach loop.
**foreach($data2['wow_accounts']['0']['characters'] as $key => $item) {
echo '<tr>';
echo '<td>';
echo $item['name'];
echo '</td>';
echo '<td>';
echo $item['realm']['name'];
echo '</td>';
echo '<td>';
echo '<button class="btnSelect">Select</button>';
echo '</td>';
echo '</tr>';
}
echo '</table>';**
I want that the script checks inside of the table "y4qt2_jsn_users" of the mysql database and under a certain id number, if the "params" entry is "ja". If this is true then this certain table row should get another tr class.
My idea is something like that, but how can i combine this with my foreach table loop?
$result = mysqli_query("SELECT params FROM xxx_users WHERE params = 'ja' AND id= '$id'");
if(mysqli_num_rows($result) == 0) {
// row not found, just loop without a certain <tr class=""
} else {
// row found, give this row a <tr class=""
}
Here is a screenshot of what I want. If the mysql condition "params=ja" is true the whole row should get a new tr styleclass, not just a cell.

Assuming I understand correctly, this should work. Please sanitize database queries (especially if there is user input at any point). But as mentioned in the comments, I don't know where $id is set, and actually presume it's a value in the $item array, so maybe replaced with $item['Id']
foreach($data2['wow_accounts']['0']['characters'] as $key => $item) {
$result = mysql_query("SELECT params FROM y4qt2_jsn_users WHERE params = 'ja' AND
id= '$id'");
if(mysql_num_rows($result) == 0) {
$class_string = '';
} else {
$class_string = ' class="my-additional-class"';
}
echo '<tr'.$class_string.'>';
echo '<td>';
echo $item['name'];
echo '</td>';
echo '<td>';
echo $item['realm']['name'];
echo '</td>';
echo '<td>';
echo '<button class="btnSelect">Select</button>';
echo '</td>';
echo '</tr>';
}
There are a lot of ways to clean this up, and if you wanted fewer lines of code you can replace the entire if else block and the $class_string variable by using ternary operators inline. The goal was to make it easy for you to read and simple to understand. (I also prefer very verbose code myself)
