Admin Login Error for Lib

[ertewebmaster]

Hello,

I have this error when I try to access to the admin section:

Failed to serialize field user with value josejose
Fatal error: Cannot use object of type PEAR_Error as array in D:\xampp\htdocs\biblioteca\dataface\Dataface\Serializer.php on line 78

I've change admin name with jose and deactivated the password. I had the same error with those originals parameters.

Anybody can help me? Thanks.

Merry Chritsmas and best wishes for the New Year.

Jose

Hmm... This is a strange error. In the default install there are no fields in any table named 'user'. Have you added a field by that name?

[ertewebmaster]

Hi,
This is the users table I have.

userid int(11) Null=No auto_increment
username varchar(32) latin1_swedish_ci Null=No password varchar(32) latin1_swedish_ci Null=Sí NULL
role enum('READ ONLY', 'ADMIN') latin1_swedish_ci Null=No READ ONLY

I have no user named user, the only one I have is Jose and his role is Admin.

Thanks.

I can't seem to find any error messages that match exactly the errors listed here. Are these the exact messages you get, or have your paraphrased some of it?

Questions:

1. What version of librariandb are you using?
2. Can you please check the dataface/Dataface/Serializer.php file and let me know what is on line 78 and the surrounding lines?

Hi,

The version is 0.2 309.

And here is the serializer.php.

* into a database. Note that this output is not escaped. You will still have to do that.
*
* @param $fieldname The name of the field from which this value supposedly comes.
* @param $value The value to be serialized.

Actually, I was curious what was on line 78 of your Serializer.php class?

Code: Select all
