This is my first question on stackoverflow :) I need to import a csv file with product features values longer than 128 characters. How can I extend the maximum size of product features values in prestashop 1.6?

推荐答案

特征值字段的长度应该是 255 个字符，除非您使用了一些特殊字符或不同的编码.

The feature value field should be 255 characters long, unless you are using some special characters or different encoding.

无论如何，将 ps_feature_value_lang 表中的列类型更改为您的首选项，

Anyway, change the column type in ps_feature_value_lang table to your preference,

然后覆盖 FeatureValue.php 类.在 override/classes/FeatureValue.php 和这个文件里面创建一个文件:

Then make an override for FeatureValue.php class. Make a file at override/classes/FeatureValue.php and inside this file:

class FeatureValue extends FeatureValueCore
{
    /**
 * @see ObjectModel::$definition
 */
public static $definition = array(
    'table' => 'feature_value',
    'primary' => 'id_feature_value',
    'multilang' => true,
    'fields' => array(
        'id_feature' => array('type' => self::TYPE_INT, 'validate' => 'isUnsignedId', 'required' => true),
        'custom' =>     array('type' => self::TYPE_BOOL, 'validate' => 'isBool'),

        // Lang fields
        'value' =>      array('type' => self::TYPE_STRING, 'lang' => true, 'validate' => 'isGenericName', 'required' => true, 'size' => 255),
    ),
);
}

修改 'size' =>255 匹配 db 列.

Modify 'size' => 255 to match the db column.
