Installing an extension and creating extra data tables seems like a waste of energy and extra work for the server for no real reason. All that is needed is to see if the title in the database is the same as the one requested so a simple PHP strcasecmp() (case-insensitive string comparison) is all that is needed but the code is so scattered I can't seem to find the line that pulls the name from the DB.
doing a search in the searchbox seems to work this way but i'm trying to make it easier for users to add new articles with the '?action=edit' URL parameter which seems to be case sensitive. but can't find the line where the DB title is compared against user input so I add that simple PHP function call. Does anyone know which php file contains the DB call or where that comparison is made using the '?action=edit' URL parameter?
