Forms and PHP_SELF

[Anon]

Hi
Can anyone tell me how, if I click 'back' whilst having typed in values in a form, to get those values to show up again when using PHP_SELF.

No matter what I try I cant get it to happen?

if you have <input type="text" name="username" value=""> then you won't be able to. you need to leave off the value="" part. the reasoning is that in IE when you click back, if any <input>'s have pre-determined values (ie. "", null), they will default back to them upon clicking back. it shouldn't have anything to do with PHP_SELF.

hope this is what you wanted, you didn't give me much information to work with 😉

Hi
all of that I've got, Iøve tried value=\"$value_i_need\" to no avail?

is it text boxes? if you want textboxes and the like to stay the same between clicking 'back' then you need to have: <input type=\"text\" name=\"variable_name\">

this will result in the script passing a $variable_name to your <form action> tag. don't even include the value= part in your <input> tags.

if you still are unsure, please post your html form and your script and i will be able to help you more specifically.

some of the switch statement is just error checking I neglected to remove!

[fandelem]

okay. i was totally offbeat on what you were asking and what i was thinking.

i think i know what you want. you are using sessions; you need the session_cache_limiter function

check it out here: http://www.php.net/manual/en/function.session-cache-limiter.php

hope this could be of help

(if not, i'm unsure ;o)
