From: Galen Charlton Date: Wed, 14 Apr 2021 18:30:39 +0000 (-0400) Subject: LP#1923225: have search highlighting stored procedure do HTML-escaping X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=4cc6c476698e7c28e3e49e45006fd4ec10df0b81;p=evergreen%2Fmasslnc.git LP#1923225: have search highlighting stored procedure do HTML-escaping This patch builds on the previous work to have the stored procedures that produced highlighted and unhighlighted versions of display attributes HTML-escape the source values, then adjusts the TPAC and Bootstrap templates to avoid double-escaping.
