At the top of the page i have this code: (it always echos 'in else loop', i dont understand what is wrong with this simple thing.)\[code\]if ($_POST['ok']){if (isset($_GET['from'])){$tmp_fromdate=$_GET['from'];$tmp_todate=$_GET['to'];echo "in if loop<br/>";echo $tmp_fromdate. " ". $tmp_todate."<br/>";$from_date=date("Y-m-d", strtotime($tmp_fromdate));$to_date=date("Y-m-d", strtotime($tmp_todate));echo $from_date. " ". $to_date."<br/>";$fdate=date("F d Y", strtotime($tmp_fromdate));$tdate=date("F d Y", strtotime($tmptodate));}else{echo "in else loop<br/>";$start_date='2010-08-01';$end_date=date ("Y-m-d");$sdate=date("F d Y", strtotime($start_date));$edate=date("F d Y", strtotime($end_date));}}<form id="form1" name="form1" method="post"><div class="demo"><label for="from">From</label><span id="sprytextfield1"><input type="text" id="from" name="from" /><span class="textfieldRequiredMsg">mm/dd/yyyy format only.</span></span><label for="to">to</label><span id="sprytextfield2"><input type="text" id="to" name="to" /><span class="textfieldRequiredMsg">mm/dd/yyyy format only.</span></span><input type="submit" id="ok" name= "ok" value="http://stackoverflow.com/questions/3762497/Change Dates"/><input type="hidden" name="from" VALUE="http://stackoverflow.com/questions/3762497/<? echo($from);?>"/><input type="hidden" name="to" VALUE="http://stackoverflow.com/questions/3762497/<? echo($to);?>"/></div></form>\[/code\]
