爲什麼這總是保存數據，即使這些字段是空的？

Question

我有這個模型http://pastebin.com/tSaTvLxW，這是我的控制器http://pastebin.com/iWeyvF71，這是相關的視圖add.ctp http://pastebin.com/YWqwMtqx，但是當我添加一個新的信息記錄，即使教育，經驗是空的總是記錄創建在各自的表中，我不不知道是什麼原因導致這種行爲，能幫助我找到這個嗎？

當我運行它，我看到下面的這 - $>請求 - >數據：

Array 
(
    [Information] => Array 
     (
      [name] => Test 
      [lastname] => Name 
      [email] => test@example.com 
      [mobile_phone] => 1561561566 
      [home_phone] => 1521521522 
      [address] => 123 Any Street 
      [other_information] => Other information 
      [picture] => Array 
       (
        [name] => avatar.png 
        [type] => image/png 
        [tmp_name] => /tmp/php2Jvveh 
        [error] => 0 
        [size] => 89486 
       ) 

     ) 

    [Education] => Array 
     (
      [0] => Array 
       (
        [education_content] => 
       ) 

     ) 

    [Experience] => Array 
     (
      [0] => Array 
       (
        [experience_content] => 
       ) 
     ) 
) 

你會發現，教育陣列和陣列的經驗，而空，仍然在存在$this->request->data。因爲您正在使用$this->Information->saveAll($this->request->data)，它會將一組空白數據保存到表格中。如果您不想保存空白數據，請檢查數組以查看它是否爲空。如果是，請在saveAll之前取消設置。你有你的表單設置的方式，它會是這樣的：

if (empty($this->request->data['Experience'][0]['experience_content'])) { 
    unset($this->request->data['Experience']); 
} 
if (empty($this->request->data['Education'][0]['education_content'])) { 
    unset($this->request->data['Education']); 
} 
$this->Information->create(); 
    if ($this->Information->saveAll($this->request->data)) { 
    ...snip...
