So do not filter before saving to the DB. You should filter when rendering the data. You should not use both functions together - that's asking for double encoding issues. Check_markup() will run the data through your input filters and make it safe - assuming that your filters are properly set up.<br></span></div><div> </div><div><font color="#ff007f" face="bookman old style, new york, times, serif" size="4"><i><b>Nancy</b></i></font> <br></div><div><font face="arial, helvetica, sans-serif">Injustice anywhere is a threat to justice everywhere. -- Dr. Martin L.
