i have a javascript variable which contains a string with new lines and spaces e.g "a \n d" i want to pass this to php without losing any spaces or new lines. currently i am using this:
my_window = window.open("", "ChemEdit Molfile", "status=1,width=550,height=350");
urlString = "/chemedit/b.php?var=" +r;
my_window.location = urlString;
where r is the string i pass.
but if i do this in php
echo $_GET["var"];
i just get it on one line with the spaces gone
please help
You need to encode the string, you can use encodeURIcomponent() for that.
I am not sure but try using encodeURIComponent function:
my_window.location = encodeURIComponent(urlString);
urlString = "/chemedit/b.php?var=" + encodeURIComponent(r);if you're going to pass newline and spaces in an url, you have to abide by the character rules of url strings, in which spaces must be represented as '%20' and newlines '\n" is '%5Cn'. the answers above will probably do this automatically, but if you find you ever need to manually encode or adjust, here is a reference for all special ascii characters that should be converted for passing through an http header request: http://www.w3schools.com/tags/ref_urlencode.asp
