How to do something if the price is greater than $100

[hauruapai]

Hi,

I am doing a shop where there will be a certificate of Authenticity issued if the price of the product is over $100.00 and want the information to show automatically on the product info page.

I have tried this

<?php 
$main_price = zen_get_products_display_price((int)$_GET['products_id']);
echo $main_price;

If ($main_price >= 10.00)  {
echo TEXT_CERT_AUTHENTICITY ;
}
 ?>

However, it is not showing anything. I have tested that $main_price is giving the correct price for the product. I have also tested that TEXT_CERT_AUTHENTICITY can be written correctly.

I have viewed products that are over 10.00 and they are not showing the extra text. I have also tested with viewing products under 10.00 and still get nothing.

However, if I change it to $main_price <= 10.00 then the TEXT_CERT_AUTHENTICITY will show if the product is OVER $10.00 but if the product is less than 10.00 it will not show the TEXT_CERT_AUTHENTICITY

Ok, so it is doing what I want it to do, but I would like to understand why the <= (less than or equal to) gives greater than or equal to results and the >= gives less than or equal to results.

What am I doing wrong? I am not really familiar with php only asp.

Thank you!

More info:

However, evey now and again all products show the TEXT_CERT_AUTHENTICITY regardless of price, then sometimes all products show no TEXT_CERT_AUTHENTICITY regardless of price.

Using the Zen Cart v1.3.7.1/v1.3.7.1 on windows server running PHP Version 5.1.1

Thank you for your time

Display price is just that, a display ... this is not a numeric value ...

Something like this can help but be aware when attributes are involved then the products_id must include the attributes to show the price or it will not validate. This takes some of your code but adds additional code to the look up:

<?php
$main_price = zen_get_products_display_price((int)$_GET['products_id']);
echo 'I see price in alpha form: ' . $main_price . ($main_price > 0 ? ' YES' : ' NO') . '<br>';
$products_lookup = $_SESSION['cart']->get_products();
$not_in_cart = true;
for ($i=0, $n=sizeof($products_lookup); $i<$n; $i++) {
  if ($products_lookup[$i]['id'] == $_GET['products_id']) {
    $not_in_cart = false;
    echo 'products_lookup price only if in cart: ' . $products_lookup[$i]['final_price'];
  }
}
if ($not_in_cart == true) {
  echo 'products_lookup price NOT in cart ';
}

If ($main_price >= 10.00)  {
echo TEXT_CERT_AUTHENTICITY ;
}
 ?>

To see prices that are in the cart that do not show, go to the shopping cart and click the link back to the product ... more than likely this is a product with attributes and now the products_id has the attributes added to get the full price ...

There are other methods but this might give you an idea of where to start ...
