    Default Facebook secure url, shared

    On my Facebook Page Tab if the visitor is viewing the page securely, my page does not receive $_REQUEST['signed_request'] from Facebook.

    The page works fine when people are viewing the page via http but when using https and the shared ssl cert it appears $_REQUEST is being stripped during the redirect.

    Any insight would be helpful.

    Thanks.

    If I were you I'd check your error_log files. Maybe they can shed some light on it?

    Default Shared certs and forms

    This is a follow up to the thread entitled "Facebook secure url, shared".

    I created to test pages:

    1) form.php a form with a single hidden element and a submit button
    2) process.php the action to form.php and simply echo's $_POST

    Everything works as expected when both pages use http://

    However, when I set the action of form.php to
    Code:
    https://echo.gendns20.com/~mydomain/process.php
    the $_POST array is empty.

    So either, a) GH is not forwarding the info or b) I am not using the shared cert properly

    Any advice would be greatly appreciated.

    $_POST array is empty when submitting a form to a page that uses shared cert url

    Hello Scott,

    You have created another thread. I moved reply to this one.

    I'm looking your script. But it doesn't worked even with http. Did you check this?

    Thanks David.

    I did test it and it works fine with http. Not exactly sure what you are looking at because I haven't posted accurate url's, I just through the faux shared cert address in there as an example.

    The code if you care which couldn't be anymore simple is as follows:

    form.php (plain)
    HTML Code:
    <form method="post" action="process.php">
        <input type="hidden" name="field" value="field value" />
        <button type="submit">Save</button>
    </form>
    form.php (with faux shared cert)
    HTML Code:
    <form method="post" action="https://echo.gendns20.com/~mydomain/process.php">
        <input type="hidden" name="field" value="field value" />
        <button type="submit">Save</button>
    </form>
    process.php
    PHP Code:
    <pre>
    <?php print_r($_POST); ?>
    </pre>

    I've made a simple script to test and it works correct:

    glowform.php:
    Code:
    <form method="post" action="https://echo.gendns20.com/~someusername/glowprocess.php">
    <label>First Name: </label>
    <input type="text" name="fname">
    
    <input type="submit" name="submit" value="submit">
    
    </form>
    glowprocess.php
    Code:
    <pre>
    <?php print_r($_POST); ?>
    </pre>
    As result:

    HTML Code:
    Array(    [fname] => David    [submit] => submit)
    Please check it too.

    I found your account on the server You can see my files in the same folder.

    By the way, I think that problem was with redirect to www.domain.com. I've disabled it in your .htaccess file.

    # RewriteCond %{HTTP_HOST} !^(www) [NC]
    # RewriteRule ^(.*)$ http://www.domain.com/$1 [L,R=301]
