如何在 Codeigniter 中为多个表创建一个搜索模块？

Question

我必须搜索“Professional”或“Vendor”表以及“Users”表。你能帮我解决一下我如何在一次搜索中实现它的查询，以决定搜索属于哪里。

下面的结果是在表格中寻找匹配项..我不想要那个..我想要两个单独的表格中的正确匹配..有人可以帮助我吗？

<?php

$this->db->select('*');
$this->db->from('users');
$this->db->join('professional', 'professional.accountId = users.id');
$this->db->join('vendor', 'vendor.accountId = users.id');
$this->db->like('users.realname', $search_term);
$this->db->or_like('users.email', $search_term);
$this->db->or_like('users.category', $search_term);
$this->db->or_like('users.full_name', $search_term);
$this->db->or_like('users.license_id', $search_term);
$this->db->or_like('professional.state', $search_term);
$this->db->or_like('professional.city', $search_term);
$this->db->or_like('professional.country', $search_term);
$this->db->or_like('professional.pincode', $search_term);
$this->db->or_like('professional.mobile', $search_term);
$this->db->or_like('professional.phone', $search_term);
$this->db->or_like('professional.profession', $search_term);
$this->db->or_like('vendor.state', $search_term);
$this->db->or_like('vendor.city', $search_term);
$this->db->or_like('vendor.country', $search_term);
$this->db->or_like('vendor.pincode', $search_term);
$this->db->or_like('vendor.mobile', $search_term);
$this->db->or_like('vendor.phone', $search_term);
$this->db->or_like('vendor.firm_catagory', $search_term);
$this->db->group_by("users.id");

$query = $this->db->get();

$qu = $query->result_array();

foreach ($qu as $row) {

$row_set[] = htmlentities(stripslashes($row['accountId'])); //build an array
}

echo json_encode($row_set);

?>

我自己找到了答案：但我想打印更多结果，如 $row['country']、$row['city']、$row['state'] 等。）

<?php

$this->db->select('*');
$this->db->from('users');
$this->db->join('professional', 'professional.accountId = users.id');
$this->db->like('users.realname', $search_term);
$this->db->or_like('users.email', $search_term);
$this->db->or_like('users.category', $search_term);
$this->db->or_like('users.full_name', $search_term);
$this->db->or_like('users.license_id', $search_term);
$this->db->or_like('professional.state', $search_term);
$this->db->or_like('professional.city', $search_term);
$this->db->or_like('professional.country', $search_term);
$this->db->or_like('professional.pincode', $search_term);
$this->db->or_like('professional.mobile', $search_term);
$this->db->or_like('professional.phone', $search_term);
$this->db->or_like('professional.profession', $search_term);
$this->db->group_by("users.id");

$query = $this->db->get();

$qu = $query->result_array();

foreach ($qu as $row) {

$row_set[] = htmlentities(stripslashes($row['accountId'])); //build an array
}
if (isset($row_set)) {

echo json_encode($row_set);

}
