I lose data when i click on back button

Hello,

I have got a back button:

<INPUT TYPE="BUTTON" VALUE="&lt;&lt; Go Back" 
ONCLICK="window.history.back()">

PHP:

when i click it i lose data on 1 field. if i leave this field empty and submit then go back the other fields are fine.

This is the field causing problem.

<input name="demo3" id="demo3" type="text" value="<?=$row['order_collect_time'];?>" size="25" onclick="javascript:NewCal('demo3','ddmmmyyyy',true,24)">

PHP:

What can i do to solve this problem. I can not use sessions.

thanks

 

what do you wanna do? I didn't understand the problem here..

 

i have got a form and i have got fields. When i fill the form and click, i go to next page to see the data i filled. If there is something wrong on the data i go back to the first page to change it.

when i go back i lose all the data i entered. This is happening because of this field

<input name="demo3" id="demo3" type="text" value="<?=$row['order_collect_time'];?>" size="25"
 onclick="javascript:NewCal('demo3','ddmmmyyyy',true,24)">

PHP:

if i leave this field empty and come back, all the data remains same.

 

why dont you just use sessions?
if you cant use sessions use cookies.
if you cant use cookies use hidden inputs.
if you cant use hidden inputs use GET.
