$php_self

[w3it]

Hi
I have an error in my shopping cart and think I have pinpointed it to this if statement. There are a few if statements like this that should execute but are not doing so.

The name of the file is shopping_cart.php and the variable FILENAME_SHOPPING_CART evaluates to this.

if (strstr($PHP_SELF, FILENAME_SHOPPING_CART)) {
  echo '    <td align="center" valign="top">' . tep_draw_checkbox_field('cart_delete[]', $products[$i]['id']) . '</td>' . "\n";
}

Any information greatly appreciated.

Thanks

Well, an actual explanation of your error would help, but either way, try using $_SERVER['PHP_SELF'] instead of $PHP_SELF

the error is that the IF statement is not running. In other words, there are items in the cart but due to this problem they are not being displayed.

I just tested what $PHP_SELF evaluates to and for some strange reason it has a directory included:

/faks/shopping_cart.php

Any clues why this is happening?

Thanks again.

what I do not understand is that this was working. What could have changed?

Thanks

What happend is that your host or whoever updated PHP or changed the PHP settings. Before $PHP_SELF was automaticaly a global variable but now that setting has changed. Now instead of calling PHP_SELF strait you have to call it from the global array $SERVER because $PHP_SELF is no longer automaticaly global, ex: $SERVER['PHP_SELF'] Hope this helps explain it a little.

ok, we're getting somewhere. Here is a function that should return products but isnt. How can I test where it is going wrong?

For example, if this line is causing an exit, how do I check this:
if (!is_array($this->contents)) return false;

How can I check if the db is not returning data? phpMyAdmin seems to work ok to the db and returns data.

Any other tips appreciated.

function get_checklist($kID) {
global $languages_id;

  if (!is_array($this->contents)) return false;

  $products_array = array();
  reset($this->contents);
  while (list($products_id, ) = each($this->contents)) {
    //$products_query = tep_db_query("select kp.products_id, kp.products_name, kp.products_model, kp.products_price, kp.final_price, kp.products_quantity, p.products_tax_class_id from " .TABLE_KITS_PRODUCTS . " kp, " . TABLE_PRODUCTS . " p where kp.kits_id='" . $kID . "' and kp.products_id = p.products_id");
	$products_query = tep_db_query("select products_id, products_name, products_model, products_price, final_price, products_quantity from " .TABLE_KITS_PRODUCTS . " where kits_id='7'"); // and kp.products_id='" . tep_get_prid($products_id) . "'

	if ($products = tep_db_fetch_array($products_query)) {
		$prid = $products['products_id'];
      	$products_array[] = array('id'         => $products_id,
                                'name'         => $products['products_name'],
                                'model'        => $products['products_model'],
                                'price'        => $products['products_price'],
                                'quantity'     => $products['products_quantity'],
                                'final_price'  => $products['final_price'],
                                'tax_class_id' => $products['products_tax_class_id']);
    }
  }

  return $products_array;
}
