display array of items from DB php/MySQL - php

Question

I am unsure how to display the items field. I want to display two tables of data; one that has all the items from a user and one with all the items to teh user. All I've been able to output is the item_id's(I pasted the html below). How to get all the item info from these ids, which is in the item table, and populate the HTML?
trans table
item table
$from = 1;
$sql = $db->prepare("SELECT * FROM test WHERE from_id = :id");
$sql->bindValue(':id', $from);
$sql->execute();
while($row = $sql->fetch())
{
$t =$row['items'];
$u =$row['to_id'];
$trans .= "<tr><th>Items</th><th>To</th><th>Status</th></tr><tr><td>$t</td>
<td>$u</td></tr>";
}
HTML DISPLAY

Try this!
<?php
$from = 1;
$sql = $db->prepare("SELECT * FROM test WHERE from_id = :id");
$sql->bindValue(':id', $from);
$sql->execute();
while($row = $sql->fetch())
{
$t =$row['items'];
$u =$row['to_id'];
$itemIDs = #explode(",", $t);
$items = array();
foreach($itemIDs as $ID){
$sqlItem = $db->prepare("SELECT itemname FROM itemtable WHERE itemid = :itemid");
$sqlItem->bindValue(':itemid', $ID);
$sqlItem->execute();
$itemname ='';
while($rowItems = $sqlItem->fetch())
{
$itemname .=$rowItems['itemname'];
}
$items[$t] = $itemname;
}
$trans .= "<tr><th>Items</th><th>To</th><th>Status</th></tr><tr><td>$items[$t]</td> <td>$u</td></tr>";
}
below is my code for testing,
<?php
$from = 1;
$sql = mysqli_query($db,"SELECT * FROM test WHERE from_id = '$from'");
while($row = mysqli_fetch_array($sql))
{
$t =$row['items'];
$u =$row['to_id'];
$itemIDs = #explode(",", $t);
$itemname ='';
foreach($itemIDs as $ID){
$sqlItem = mysqli_query($db, "SELECT itemname FROM itemtable WHERE item_id = '$ID'");
while($rowItems = mysqli_fetch_array($sqlItem))
{
$itemname .= $rowItems['itemname'].', ';
}
$items[$u] = $itemname;
}
$trans .= "<tr><th>Items</th><th>To</th><th>Status</th></tr><tr><td>$items[$u]</td> <td>$u</td></tr>";
}
echo "<table>".$trans."</table>";
?>

Note : change my queries with ur need
in ur while loop
while($row = $sql->fetch())
{
$items_array = array();
$items_array = explode(",",$row["items"]);
foreach($items_array as $key => $value)
{
//modify ur query according to ur need
$query3 = "SELECT item_name
FROM item_table
WHERE item_id =".$value." ";
$result3 = mysql_query($query3);
$row3 = mysql_fetch_assoc($result3);
$item_name .= $row3['subcategory_name'].", ";
}
}
now ur array will contains item_id,
use foreach loop in ur while loop and get info of Item from item table with item_id from expolode function

Answer 3

Within while you will have to fire new query that will get the information of items.
For eg :
"SELECT * FROM item_info_table WHERE id IN (id1,id2, id3)"
It will return you the item information corresponding to the id's.

The data is not normalized. Get it to normalize and you'll have a much better and cleaner solution.
