ergi depracation error - trying to update to preg_match

[simcoweb]

We have a client using an OLD version of Xcart that's throwing errors regarding eregi depracation due to it being written for prior to MySQL 5.3. We've run into this problem before but were able to find some examples and solutions  for converting to a preg_match updated syntax. However, this one has me a bit baffled since it doesn't fit the syntax of most of the examples and no matter how I insert the delimiters it throws an error.

 

This is the line throwing the error:

 

if (eregi("^(http|ftp)://", $v["image_path"]))

 

I've used these examples in the past for converting from eregi to preg_match: http://www.devthought.com/2009/06/09/fix-ereg-is-deprecated-errors-in-php-53/

 

But this sliver of code has an untypical format to how it's expressed. So no matter what I've tried I just can't get it right. Any help would be MUCH appreciated!

if (preg_match("~^(http|ftp)://~i", $v["image_path"]))

based on that link you provided, my guess is you tried to use / as the delimiter and then didn't escape it, since you use it in your actual pattern.  preg_match can use pretty much any non-alphanumeric character as the delimiter, but whatever you choose must be escaped if you need to use it in the actual pattern.

.josh, you are exactly right. I was using the delimiters in the examples and because they were already present it just wasn't making sense. Thanks for the quick fix and a lesson learned for life!

 

The error message IS gone.

.josh, I may have spoken too soon. Suddenly there's this error appearing:

 

Warning: Division by zero in /home/wwwpipet/public_html/shop/modules/Detailed_Product_Images/product_images.php on line 57

Warning: preg_match() [function.preg-match]: Empty regular expression in /home/wwwpipet/public_html/shop/modules/Detailed_Product_Images/product_images.php on line 57

 

That's the same line as before but when I first implemented your code modification on the test product I was viewing all errors went away. This is another product page i'm viewing, same cart, however.

 

Now, there are two other mentions of eregi on the page in a location ahead of the line we fixed, line 57. Here's lines 44 - 49:

 

if ($current_area != "C" && is_array($images)) {
foreach($images as $k=>$v) {
	$images[$k]["type"] = (eregi("gif",$v["image_type"])?"GIF":(eregi("png",$v["image_type"])?"PNG":"JPG"));
}

}

 

But, these lines are NOT the ones mentioned in the error message. Only 57 is. But, the line 57 error is now different than the original. Ideas?
