有人能幫助我嗎？

@maronl謝謝你的幫助，但它沒有奏效。

請看看這段代碼。 最好的問候。

我認爲你應該爲你的輸入數據添加一個索引。我做了一個樣本PHP頁面包含兩大塊相同的輸入型

<html> 

<head></head> 

<body> 

<h1>POST VALUES</h1> 
<pre><?php print_r($_POST); ?></pre> 

<h1>SAMPLE FORM</h1> 
<form method="POST"> 
<h2>first block</h2> 
first name 1<input name="first_name[1]" /> 
<br />last name 1<input name="last_name[1]" /> 
<br /><select name="item[1][]" multiple> 
<option value="1">primo</option> 
<option value="2">secondo</option> 
</select> 

<h2>second block</h2> 
first name 2<input name="first_name[2]" /> 
<br />last name 2<input name="last_name[2]" /> 
<br /><select name="item[2][]" multiple> 
<option value="1">primo</option> 
<option value="2">secondo</option> 
</select> 

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

</body> 
</html> 

這樣，當你提交你的數據，你必須在$ _ POST

Array 
(
    [first_name] => Array 
     (
      [1] => name 1 
      [2] => name 2 
     ) 

    [last_name] => Array 
     (
      [1] => last name 1 
      [2] => last name 2 
     ) 

    [item] => Array 
     (
      [1] => Array 
       (
        [0] => 1 
        [1] => 2 
       ) 

      [2] => Array 
       (
        [0] => 2 
        [1] => 3 
       ) 

     ) 

) 

當你打印你的盒子應該是簡單給輸入數據添加一個索引。像

$index = 0; 
foreach ($informations as $field): 
    $index++; 
    echo '<input name="name['.$index.'][]" value="'. esc_attr($field['name']) .'" />'; 
    echo '<input name="surname['.$index.'][]" value="'. esc_attr($field['surname']) .'" />'; 
    .... 

希望這可以幫助！
