hide end of url passing values

juschillinnow

If I have a url like this:

http://localhost/icart/login2.php?log_error=2

can I hide the "?log_error=2"

so the user doesn't see it in the address bar.

sarahk

Try:

<form action="dothis.php" method="post">
<input type="hidden" name="log_error" value="2">
<a href="javascript:submit();">Click me</a>
</form>

If the user views the source the log_error is still visible but it's not on the address bar and the user has be determined to find it.

Depends on how badly you want to hide it. This works fine.

Only issue with this is, if you are using tables have the <form> inside the TD and the </form> outside. Don't ask! but if you do it the way you'd expect the table gets swollen.

try these things in order.

1) do what sarahk says

if you can't

2) try storing the info in a session, call it $_SESSION['form'] to make it easier.

if you can't do that

3) I will assume you are using apache. you could look into apache url Rewriting with the oddly enough named mod_rewrite module...

i think you can use regular expressions, you could just strip off anything after '?' however i don't know offhand if that will remove it from the query string before php gets to it so perhaps php will lose them before they can be logged

the values are passed throught php, but when the code gets to this link, it is issued by window.location, not by a form

ednark

your last post doesn' t make any sense to me... please elaborate... or just post the importnat parts of the code you are using

sarah said to use a form, but the problem is, I can't because.....

The script is running, running, running, and then it comes to an if statement where is checks the vales of some items. Depending on what those values are, depends on what the script does. On a certain instance it will use javascript to do a

I cannot have any user input for a form.

So you see, i need to use it this way, but I would like to hide the ?log_error=2

woah! i don't think you should be doing what you described, let me describe to you the flow of a page request and see if that helps you see what i am thinking and what i believe you are thinking

1) user types in address, or clicks on link

2) browser sends apache a page request

3) apache notices its a php script you want

4) apache starts up php

5) apache sends php your .php file

6) php runs through you code and execues it all, returns anything printed, any html written

7) apache takes whatever is returned from php and send it to the users browser as a webpage

8) browser recieves and loads page

9) browser reads and executes any bare javascript, which may write more html

10) page executes any onLoad='' javascript

11) javascript executes in response to mouse and keyboard input from user, which may reorganize the page (ie show a dropdown menu)

ok now php and javascript can do some similar things, like tell the browser to load a new page.

if you are not sure which page the user should be on. if you need to run logic to make sure that this page is the one the user should be on, then you need to take care of that at my step 6 (with php) before your webserver returns any webpage. You are wating till step 9 (in javascript), till after the user has already recieved the page...

php has access to all the information that javascript has access to about the browser via the HTTP_USER_AGENT variable.

javascript's

    document.location = 'blah.html'

is identical in outcome to using the header() function in php

    header('Location: blah.html");

maybe this helps explain. if not maybe you can explain to me why you are waiting till javascript executes to change the users page.

you can use javascript to read form values and to write form values:

<form name="f1" action="form.php">
  <input type="hidden" name="user" value="nobody">
</form>

<script language="javascript">
    document.forms.f1.user = 'ednark';
    document.forms.f1.submit()
</script>

will send form.php the variable
'user'=>'ednark'
not
'user'=>'nobody'

#form.php
print $_POST['user']

this will print
ednark
not
nobody

Thanks for your time and description (I already knew this). This was just an example or project for one of my employees to see if it can be done. Which it can't, because the javascript can't pass the values, after php executes. It will return 0 or false.

They just didn't believe me, so it helps to hear it from someone else. Thanks.
