Error on redirect page to PayPal

Error on redirect page to PayPal

When choosing to pay with PayPal, customers come first on a redirect-page (see attach) while waiting.
But some customers get an error while redirecting to PayPal.
They are using Windows 8(.1).

Is it in my code or what can be the culprit ?


Best Regards,
Geert.

What is the error?

Impossible to know the cause of an error without knowing what the error says....

The only thing I know about the error, is the snapshot a customer mailed me.
The "Redirect-error.jpg" is in the attached zip :
"500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed."

error 500 is a generic error.

it used to mask the real error from site visitors.

We need to know what the actual error message is. your host should have an error log file that records the real message when showing the generic one on the screen

once we know the real message, we can start to determine the cause.

Hi Jason,

I found this error 500 in the log file :

2014-01-05 22:39:23 POST /Redirect.asp |989|80040e14|Number_of_query_values_and_destination_fields_are_not_the_same. - 178.118.226.183 HTTP/1.1 Mozilla/5.0+(Windows+NT+6.3;+WOW64)+AppleWebKit/537.36+(KHTML,+like+Gecko)+Chrome/31.0.1650.63+Safari/537.36 http://www.stickers.be/Checkout_PayPal.asp 500 1404

This is probably caused by the information being saved to the order or order details tables.

since it happens to some orders and not others, it is probably specific product information coming from the cart. Find out what products they ordering when the problem occurs, then look at the information that gets saved to the cart by the add to cart buttons for those products.

I would guess that there are special characters such as a single or double quote being saved to the cart, or a text value is being saved to the cart, but it is being passed to the orders / order details table as numeric

The culprit is the "vertical bar" character (|).
Customers can order a text (decal). This was his tekst : Goethals J.|O+ "Shadownight #771"
So I tried it for my own and I had also the error 500.

In the "eCart Store Details in Database", the product "cStr(WA_eCart_DisplayInfo(stickersBE, "EigenTekst"))" is stored as text.

the vert bar character will need to be converted to HTML entity.

i dont remember the ASP syntax for this, but in PHP it is:

str_replace("|", "&#124;",$value);

where $value is the string that contains the pipe character.

this is in AS VBScript :

<%  
Dim myString
myString = "|"
' vbscript replace specified with 3 required parameters such as string expression, find string and replacement string value
Response.Write(Replace(myString, "|", "&#124;"))
%>



But where do I have to place it ?

in the code for the store details:

change:
"|" & "" & cStr(WA_eCart_DisplayInfo(stickersBE, "EigenTekst")) & "" & "|"

to:
"|" & "" & cStr(Replace(WA_eCart_DisplayInfo(stickersBE, "EigenTekst"), "|", "&#124;")) & "" & "|"
