Removing blank lines from a string

(0) ShareShare
ReportReport
Posted on by Korbrm 35

I have users who are tapping enter twice at the end of an address field and when I am concatenating the street with the city I get blank lines in the address which is causing an issue with checks. I was attempting to fix it with replacing line breaks but couldn't get the desired result. Is there a way to scan each line and remove it if it is doesn't have any text?

    This is a common problem with user pressing carriage return at the end of the address.

    If you want to look if the last two characters in the street address is a carriage return then use the following:

    if(substring(Street, len(Street) - 2, 2) == "\r\n")

    {

       street = substring(street, 1, len(street) - 2));

    }

    You need to check, as I am not on a system at the moment, but you might need to use 1 character and \n rather than \r\n, can remember if it uses both or just \n.

    This will of course only check the last characters for returns. If the user pressed it multiple times, you might want to run a loop to check you get them all.

    Please mark this as an answer if you found the information useful.

    Thank you!

    Changed it around a little bit and added the loop for when they eventually add 2 carriage returns.

    while (substr(Street, strlen(Street),1) == "\n")

       {

           Street = substr(Street, 1, strlen(Street) -1);

       }
