[8] Array to string conversion: I can only add product name.

[lupradoa]

Hi,

I'm modifying the default template in order to display some custom fields needed for an online bookshop.

 

I've done this so far: 

• the 'description_short' field has been renamed as "autor"
• 'upc' is now year of publication
• 'ean13' is the edtion
• new custom field: 'colación / tapa', is the type of cover

 

Files modified:

 

Product.php

** @var string Colacion */
    public $tapa;
	
...
/* Classic fields */
'ean13' =>                        array('type' => self::TYPE_STRING,  'size' => 13),
            'upc' =>                        array('type' => self::TYPE_STRING,  'size' => 12),
...
/* Lang fields */			 'tapa' =>  						array('type' =>self::TYPE_STRING, 'lang'=>true, 'size' => 128),

			</p>

When I add a new product or I try to modify one of the already added, I've got two errors: 

 

 

1. Notice on line 258 in file /..../httpdocs/libros/tools/smarty/sysplugins/smarty_internal_templatebase.php(157) : eval()'d code

   [8] Array to string conversion

2. Any of the tabs (price, quantity... ) shows nothing but a blank screen // Cualquiera de las otras pestañas que hay para editar o crear un producto, me lleva a un espacio en blanco

3. 

Any suggestion?

Luis.
