的foreach和$ _ POST

Question

我：

<form action="save.php" method="POST"> 
<input type="text" name="test[one][]" value="a"><input type="text" name="test[two][]" value="a"> <br /> 
<input type="text" name="test[one][]" value="s"><input type="text" name="test[two][]" value="s"><br /> 
<input type="text" name="test[one][]" value="d"><input type="text" name="test[two][]" value="d"><br /> 
<input type="text" name="test[one][]" value="f"><input type="text" name="test[two][]" value="f"><br /> 
<input type="text" name="test[one][]" value="g"><input type="text" name="test[two][]" value="g"><br /> 

<input type="submit"> 
</form> 

在數據庫有：

Table: 
id | one | two 

在PHP

我想補充：

if($_POST){ 
    foreach($_POST['test'] as $post){ 
      $new = new Table(); 
      $new->setOne($post['one']); 
      $new->setTwo($post['two']); 
      $new->save(); 
    } 
} 

但是這不工作...我不能使用POST作爲索引'one'和'two' - 我必須使用兩個循環foreach。有可能用一個foreach或foreach做成foreach嗎？

的print_r（$ _ POST）返回我：

[test] => Array ([one] => Array ([0] => a [1] => s [2] => d [3] => f [4] => g) [two] => Array ([0] => a [1] => s [2] => d [3] => f [4] => g))) 

Answer 1

我會走這條路：

if (!empty($_POST)) { 
    // now $_POST['test'] is array('one' => array(), 'two' => array() 
    for ($i = 0, $c = count($_POST['test']['one']); $i < $c; ++$i) { 
    $new = new Table(); 
    $new->setOne($_POST['test']['one'][$i]); 
    $new->setTwo($_POST['test']['two'][$i]); 
    $new->save(); 
    } 
} 

Answer 2

if(is_array($_POST['test'])){ // also check that the user submitted an array 
    foreach($_POST['test'] as $post){ 
      $new = new Table(); 
      foreach ($post['one'] as $item) { // $post['one'] and $post['two'] should have the same number of elements so looping through $post['one'] is sufficient to get entries for $post['two'] 
       $new->setOne($item); 
       $new->setTwo($item); 
       $new->save(); // each item is saved in the database now 
      } 
    } 
}
