From 47c5167acb0a4a2c809c03dc664fea1d130d0c8b Mon Sep 17 00:00:00 2001 From: Lukas Fleischer Date: Thu, 20 Oct 2011 08:43:44 +0200 Subject: Escape wildcards in "LIKE" patterns Percent signs ("%") and underscores ("_") are not escaped by mysql_real_escape_string() and are interpreted as wildcards if combined with "LIKE". Write a wrapper function db_escape_like() and use it where appropriate. Note that we already fixed this for the RPC interface in commit da2ebb667b7a332ddd8d905bf9b9a8694765fed6 but missed the other places. This patch should fix all remaining flaws reported in FS#26527.
