笨和insert_batch從爆炸

Question

我有這樣的代碼：

function insertGenre() { 
    $genres = explode(',',$this->input->post('genreName')); 

    foreach($genres as $genre) { 
     $temp = array(
      'id' => null, 
      'name' => $genre, 
      'popular' => '0' 
     ); 

     $data2[] = $temp; 
    } 

    return $data2; 

    $data = array(
     'id' => null, 
     'name' => $this->input->post('genreName'), 
     'popular' => '0' 
    ); 

    //$this->db->insert('genres',$data); 
    $this->db->insert_batch('genres',$data2); 
} 

它應該運行得很好（我通過一對夫婦的問題在這裏跑），但事實並非如此。我究竟做錯了什麼？

Answer 1

它不應該是這樣的：

function insertGenre() { 
    $genres = explode(',',$this->input->post('genreName')); 

    foreach($genres as $genre) { 
     $temp = array(
      'id' => null, 
      'name' => $genre, 
      'popular' => '0' 
     ); 
     $data2[] = $temp; 
    } 

    if($this->db->insert_batch('genres',$data2)) { 
     return $data2; 
    } else { 
     return false; 
    } 
} 

在運行插入查詢之前，您正在返回。變量的第二個$data也似乎是多餘的。

我還在末尾添加了if語句，如果插入失敗，將返回false。

您需要將您的return移動到函數結束，否則將不會執行它下面的臺詞：

function insertGenre() { 
    $genres = explode(',',$this->input->post('genreName')); 

    foreach($genres as $genre) { 
     $temp = array(
      'id' => null, 
      'name' => $genre, 
      'popular' => '0' 
     ); 

     $data2[] = $temp; 
    } 

    $data = array(
     'id' => null, 
     'name' => $this->input->post('genreName'), 
     'popular' => '0' 
    ); 

    //$this->db->insert('genres',$data); 
    $this->db->insert_batch('genres',$data2); 

    return $data2; 
}
