Displaying random product in a related product table of 5 - php

Question

I am creating a row of "product related table of x5" and using MYSQLcode RAND to generate RANDOM products and a exception clause using id!='$id' - where id is existing product that is being viewed currently.
However the problem is that all the product images generated were all of the same similar product image.
Can anyone shed some light on this?
Pic for better reference:
include "MyOnlineStore/storescripts/connect_to_mysql.php";
$sql2 = mysql_query("SELECT * FROM bag WHERE id!='$id'ORDER BY RAND()LIMIT 5");
$productCount2 = mysql_num_rows($sql2); // count the output amount
if ($productCount2 > 0) {
?>
<table border="1">
<tr>
<?php
while ($row2 = mysql_fetch_array($sql2)) {
$idrelated = $row2["id"];
$imagerelated = $row2["image"];
$titlerelated = $row2["title"];
}
} else {
echo "That item does not exist.";
exit();
}
mysql_close();

Answer 1

Your code should be something like this
include "MyOnlineStore/storescripts/connect_to_mysql.php";
$sql2 = mysql_query("SELECT * FROM bag WHERE id!='$id'ORDER BY RAND()LIMIT 5");
$productCount2 = mysql_num_rows($sql2); // count the output amount
if ($productCount2 > 0) {
?>
<table border="1">
<tr>
<?php
while ($row2 = mysql_fetch_array($sql2)) {
$idrelated = $row2["id"];
$imagerelated = $row2["image"];
$titlerelated = $row2["title"];
?>
<td>
<a href="http://example.net/product.php?id=<?php echo $idrelated; ?>">
<img src="admin/product/uploaded_files/<?php echo $imagerelated; ?>" width="100" height="100" alt="<?php echo $titlerelated; ?>" />
</a>
</td>
<?php
}
?>
</tr>
</table>

Answer 2

As far as I can see from your code, the following variables:
$idrelated, $imagerelated, $titlerelated
remains unchanged after leaving the loop. So in each line you refer to the same variable and value.
If you want to keep use some array to keep all five values:
<?php
$index = 0;
while (...) {
$relatedA[$index] = ...;
$relatedB[$index] = ...;
$relatedC[$index] = ...;
$index++;
}
?>
...
<?php echo $relatedA[0]; ?>
<?php echo $relatedA[1]; ?>
...
<?php echo $relatedA[4]; ?>
The last you can put in the loop again to avoid redundant code.
UPDATE
Try to resist the temptation of putting echoes into the first loop where you fetch values - as it could result in hard to maintenance spaghetti-style code (unfortunately quite commonly seen in many php sources).
