I’m trying to implement single sign-on. Don’t need to go into implementation details on that, but they want a BASE64 encoded JSON string of relevant user data. Like so:

<?php
$data = array(
       "id" => "{logged_in_member_id}",
        "username" => "{logged_in_username}",
        "email" => "{logged_in_email}"
);

$message = base64_encode(json_encode($data));
?>

Except. Even though EE is setting the info in the $data array correctly (i.e. [id] => “1”), when it’s base64’d, it’s encoding [id] => “{logged_in_member_id}” as a string literal.

Here’s a stripped down example code that I’ve found will work in any PHP-enabled template. I’ve tried on input and output (seems output should be the right one), but it doesn’t seem to make a difference.

<?php
$data = array(
       "id" => "{logged_in_member_id}",
        "username" => "{logged_in_username}",
        "email" => "{logged_in_email}"
);

$message = base64_encode(json_encode($data));

print(json_encode($data) . "

");

print($message);

?>




If the base64 string matches this: 

eyJpZCI6Intsb2dnZWRfaW5fbWVtYmVyX2lkfSIsInVzZXJuYW1lIjoie2xvZ2dlZF9pbl91c2VybmFtZX0iLCJlbWFpbCI6Intsb2dnZWRfaW5fZW1haWx9In0=



it decodes to this (not what I want) : 


<!-- spaced out to prevent EE from interpreting -->
{"id":"{
logged_in_member_id
}","username":"{
logged_in_username
}","email":"{
logged_in_email
}"}

This should be able to work, right? I’m on version 2.1.3. As a note, if you use the PHP base64_decode function and it decodes to {logged_in_username}, EE will interpret that and print the username. So I’ve been using a decoder website instead of the function.

Any help is much much appreciated. Thanks!

My issue and yours are related.  How are you getting an EE tag to ever work within php?  I have my template setting to “Output” and it parses everything literal.

Ah, I’m pretty sure it’s a parse order thing, where it turns out that there is a fair amount of EE tags that are still not processed until after PHP Output: http://expressionengine.com/wiki/Parse_Order/ . Including standard variables, which is what I really want in this case. Not sure how to get around this.

I think one just has to get the info that’s from the standard variables directly with PHP. http://ellislab.com/forums/viewthread/82379/ . Funny how we both had the same problem right now!

Ok, I figured out my issue.  These two resources should help you:

http://ellislab.com/expressionengine/user-guide/development/usage/session.html
http://ellislab.com/expressionengine/user-guide/development/usage/database.html

Try This:

<?php
$data = array(
        "id" => '".$this->EE->session->userdata('member_id')."',
        "username" => '".$this->EE->session->userdata('username')."',
        "email" => '".$this->EE->session->userdata('email')."'
);

$message = base64_encode(json_encode($data));
?>

This is how I was using it:

UPDATE `my_table` 
SET `my_field` = `my_field`+".$_POST["data"]." AND `my_field_2` = `my_field_2`-".$_POST["data2"]." 
WHERE `my_field_4` = '".$this->EE->session->userdata('member_id')."' 
LIMIT 1;

Hopefully this information helps you as well.  😊

Hallelujah! I did

$data = array(
       "id" => $this->EE->session->userdata('member_id'),
        "username" => $this->EE->session->userdata('username'),
        "email" => $this->EE->session->userdata('email')
);

and all is well.

Hi struiling,

Glad you got that worked out. Is there anything else that you need help with?

@nnette, Thanks for the assist.

All set, thanks.

Great, going to close this thread. Feel free to post again when needed.
