Replacing my "Add to Cart" link with "Out of Stock" - php

Question

I'm trying to, for the sake of a class project, create a mock-up store. My tools are XAMPP 3.2.2 and phpMyAdmin. An actual, functioning "Add to cart" button will come later(Right now I'm just using a link as a placeholder), but for the time being, I'm trying to figure out how to replace the button/link with a message reading "Out of Stock" when the Stock is 0.
Here's the code I'm using to display the product page; it's almost certainly messy, and there's probably a dozen better ways to do it, but for now, it gets the job done:
<?php
$sql = "SELECT * FROM webstore.Products order by category";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo '<table border="2" width="100%">';
echo '<tr>';
echo ' <td width="20%">' . $row["Name"] . '</td>';
echo ' <td width="20%">' . $row["Descr"] . '</td>';
echo ' <td width="20%">' . $row["Price"] . '</td>';
echo ' <td width="20%">' . '<img src =' . $row["IconURL"] . '>' . '</td>';
echo ' <td width="20%">' . 'Add to cart' . '</td>';
echo ' </tr> ';
echo '</table>';
}
} else {
echo "0 results";
}
The output looks like this:
Results
I'm not looking for "better practices;" right now, I just need a way to replace the shopping cart link with "Out of Stock" when the product stock is 0.

Answer 1

add a check to the while loop some what like:
while($row = $result->fetch_assoc()) {
echo '<table border="2" width="100%">';
echo '<tr>';
echo ' <td width="20%">' . $row["Name"] . '</td>';
echo ' <td width="20%">' . $row["Descr"] . '</td>';
echo ' <td width="20%">' . $row["Price"] . '</td>';
echo ' <td width="20%">' . '<img src =' . $row["IconURL"] . '>' . '</td>';
if($row['stock'] >0){
echo ' <td width="20%">' . 'Add to cart' . '</td>';
}else{
echo '<td width="20%">Out of Stock</td>';
}
echo ' </tr> ';
echo '</table>';
}
