我构建了一个查询:
public function getContacts($limit, $start, $search)
{
$this->db->limit($limit, $start);
if (!empty($search)) {
$this->db->like('name', $search);
$this->db->or_like('last_name', $search);
$this->db->or_like('phone_number', $search);
$this->db->or_like('created_at', $search);
$this->db->or_like('note', $search);
}
$query = $this->db->get_where('contact', array('user_id' => 3));
return $query->result_array();
}
但是where子句不起作用。它应该仅返回user_id等于3的结果,但它返回所有内容。
有什么问题?
这是执行的查询:
SELECT * FROM `contact` WHERE name LIKE '%stefano%' ESCAPE '!' OR last_name LIKE '%stefano%' ESCAPE '!' OR phone_number LIKE '%stefano%' ESCAPE '!' OR created_at LIKE '%stefano%' ESCAPE '!' OR note LIKE '%stefano%' ESCAPE '!' AND `user_id` = 3 LIMIT 2
在Workbench中尝试此查询并仍然忽略AND user_id = 3。 如果我的逻辑没有错,它应该只返回user_id = 3但返回all的行。

你需要添加group_start()和group_end()。就像这样。
if (!empty($search)) {
$this->db->group_start();
$this->db->like('name', $search);
$this->db->or_like('last_name', $search);
$this->db->or_like('phone_number', $search);
$this->db->or_like('created_at', $search);
$this->db->or_like('note', $search);
->group_end();
}

试试这个
public function rules()
{
return [
'name' => 'required|max:255|unique:products,name'.$product->id,
'description' => 'required',
'price' => 'required|numeric|max:500',
'stock' => 'required|max:6',
'discount' => 'required:max:2'
];
}

试用此代码:
public function getContacts($limit, $start, $search)
{
$this->db->limit($limit, $start);
if (!empty($search)) {
$this->db->select(*);
$this->db->like('name', $search);
$this->db->or_like('last_name', $search);
$this->db->or_like('phone_number', $search);
$this->db->or_like('created_at', $search);
$this->db->or_like('note', $search);
}
$this->db->select(*);
$this->db->where('user_id','3');
$query = $this->db->get('tablename');
return $query->result_array();
}
