fields 一处BUG

[ziqiming]

$this->fields('id' , 'gid' , 'image' , 'number' , 'price' , 'select')->find(3);

这样的时候会报错，修复办法
doitphp -> Model.php -> fields

找到

$fieldName = implode(',', $new);

替换为

$new = []; 
foreach ($fieldName as $key => $value) {
    array_push($new ,  '`' . $value . '`' );
}
$fieldName = implode(',', $new);
unset($new);
