Please explain how to use forms/posting data

[eluser]solepixel[/eluser]
I am having the hardest time using forms to perform the simplest of operations:

using the code:

Code:

$formAttr = array('id' => 'new_account');
echo form_open(uri_string(), $formAttr);
    echo form_fieldset('Personal Information');
    $input = array(
        'name' => 'f_name',
        'id' => 'f_name',
        'value' => set_value('f_name'),
        'class' => 'text'
    );
    
    echo form_label('First Name','f_name');
    echo form_input($input);
    echo form_submit('submit', 'Submit', 'id="submit_btn"');

    echo form_fieldset_close();

echo form_close();

for some reason, using set_value() is still not retaining my post values. It's almost as if my page is doing a redirect after form variables are being submit. If i try to refresh after a POST, i do not get the dialog "Are you sure you want to resend post data.. blah blah blah".

The only way i could get it to work is to post from /onepage/ to /onepage/?withquery and that would retain my post variables. however posting from /onepage/?withquery to /onepage/?withquery causes the same issue as before and loses post variables.

Any ideas what is going on here?

Ok. so I've narrowed down the problem.

In my .htaccess file, i'm adding a '/' to the end of the URL if it does not already end in a '/' or '.[ext]'.
here's that code:

Code:

# If requested resource does not exist as a file
    RewriteCond %{REQUEST_FILENAME} !-f
    # and does not end with a period followed by a filetype
    RewriteCond %{REQUEST_URI} !\..+$
    # and does not end with a slash
    RewriteCond %{REQUEST_URI} !/$
    # then add a trailing slash and redirect
        RewriteRule (.*) $1/ [R=301,L]

well, this poses a problem when using form_open() + uri_string() because it automatically converts your action attribute to the FULL URL of the site (which is a bit rediculous). Somewhere during that process, the uri loses the '/'.

So to solve this issue, in the config file, I changed this:

Code:

$config['url_suffix'] = "/";

I guess now I want to know why CodeIgniter uses the FULL SITE URL (http://blahblah/) on all functions like form_open() and anchor() etc. Also, why haven't they provided an option to disable this feature. It seems a bit useless. Why not just use '/' in place of 'http://garbledgoop/'. If it's not useless, i'd really like to know why it's done that way.

set_value() is part of the validation library, are you using it in your controller? Post your controller.
