I'm having the strangest issue with codeigniter. I have a site that has a search feature which displays the person's query in the url so that they can save the url. I make sure that the query text has gone through rawurlencode before I stick it in the url. However, Codeigniter still shoots me to an error page when there's a character in the query that isn't in my permitted_uri_characters configuration.
So even though my browser says /search-results/query/%22samplequery%22, I’m still getting the error about using non-permitted characters.
Is this a bug? I don’t have non-permitted characters in my url. I have a % sign and some numbers (which are all specifically permitted). It’s definitely the permitted_uri_characters setting that’s giving me grief. If I add a quotation mark to it, it allows the %22 query through no problem.
And to be clear, the query is coming from a form as post data, then being encoded in my controller and then redirected to a new page. There’s no way that the permitted_uri_characters is somehow being applied BEFORE it gets encoded.
This is driving me batty, as my only solution at the moment is to open up my permitted_uri_charcters to everything under the sun, which isn't very secure!
