獲取陣列

Question

中的最後一個值，我使用笨，我只得到來自從模型來數組的最後一個值。我需要所有在foreach條件下運行的值。

我的控制器代碼是

$inst_id = $this->session->userdata['int_url_id']['int_id']; 
    $result['data']=$this->formbuilder_Model->check_example_fields($inst_id); 
    print_r($result['data']);// Here I am getting the last value 
    $this->load->view('user-example-form',$result);//passing elements to the view page 

型號

public function check_example_fields($inst_id) 
{ 
    $sql_elements="SELECT inst_id,form_builder_type, form_elements,form_last_modified FROM `form_builder` WHERE inst_id=$inst_id AND form_builder_type='example' ORDER BY form_last_modified DESC LIMIT 1"; 
    $query = $this->db->query($sql_elements);// I am getting the last row 
    $row = $query->row(); 
    $abc=explode(',',$row->form_elements);//I am getting output 

    foreach ($abc as $value) { 
     $sql_elements_get="SELECT fields_name, fields_type FROM `tbl_form_builder_fields` WHERE fields_name='".$value."'"; 
     $fetch_query = $this->db->query($sql_elements_get); 
     $row1 = $fetch_query->result(); 
    } 
    return $row1;// It it return only last value 
} 

我知道我會得到最後的值，但是否有任何其他選項，讓所有的值，並傳遞給控制器？

Answer 1

，就應該替換該行：

$row1 = $fetch_query->result(); 

與此：

$row1[] = $fetch_query->result(); 

附： 我想你可以通過使用mysql IN或FIND_IN_SET運算符來避免foreach循環。

Answer 2

需要週期中的第二查詢結果;）

public function check_example_fields($inst_id) 
{ 
    $sql_elements="SELECT inst_id,form_builder_type, form_elements,form_last_modified FROM `form_builder` WHERE inst_id=$inst_id AND form_builder_type='example' ORDER BY form_last_modified DESC LIMIT 1"; 
    $query = $this->db->query($sql_elements);// I am getting the last row 
    $row = $query->row(); 
    $abc=explode(',',$row->form_elements);//I am getting output 
    $results = []; 
    foreach ($abc as $value) { 
    $sql_elements_get="SELECT fields_name, fields_type FROM `tbl_form_builder_fields` WHERE fields_name='".$value."'"; 
    $fetch_query = $this->db->query($sql_elements_get); 
    foreach ($fetch_query->result() as $r) 
    { 
     $results[] = $r; 
    } 
    } 
    return $results;// It it return all values 
} 

Answer 3

public function check_example_fields($inst_id) 
{ 
    $sql_elements="SELECT inst_id,form_builder_type, form_elements,form_last_modified FROM `form_builder` WHERE inst_id=$inst_id AND form_builder_type='example' ORDER BY form_last_modified DESC LIMIT 1"; 
    $query = $this->db->query($sql_elements);// I am getting the last row 
    $row = $query->row(); 
    $abc=explode(',',$row->form_elements);//I am getting output 
    $datanew = array();  
    // start your copy code here 
    foreach ($abc as $value) 
    { 
     $sql_elements_get="SELECT fields_name, fields_type FROM `tbl_form_builder_fields` WHERE fields_name='".$value."'"; 
     $fetch_query = $this->db->query($sql_elements_get); 
     $datanew[] = $fetch_query->result(); 
    } 
    // end your copy code here 

    $last_row = end($datanew); 

    $data['alldata'] = $datanew; 
    $data['lastrow'] = $last_row; 
    return $data; 
}

使用ROW1作爲一個數組，並把它分配的結果。

public function check_example_fields($inst_id){ 
     $sql_elements="SELECT inst_id,form_builder_type, form_elements,form_last_modified FROM `form_builder` WHERE inst_id=$inst_id AND form_builder_type='example' ORDER BY form_last_modified DESC LIMIT 1"; 
     $query = $this->db->query($sql_elements);// I am getting the last row 
     $row = $query->row(); 
     $row1 = array(); //define array here 
     $abc=explode(',',$row->form_elements);//I am getting output 
     foreach ($abc as $value) { 
      $sql_elements_get="SELECT fields_name, fields_type FROM `tbl_form_builder_fields` WHERE fields_name='".$value."'"; 
      $fetch_query = $this->db->query($sql_elements_get); 
      $row1[] = $fetch_query->result(); 
     } 
     print_r($row1); 
     return $row1;// It it return only last value 
    }
