Question

我试图通过遍历在php中调用函数时生成的行来获取正确的结果，但是我只得到一行而不是所有行。下面的代码我有。

<form method="post" action="done.php">
<div id="add_passenger">
  <div class="fields">  
   <input type="text" name="field[email]" />
   <input type="text" name="field[name]" />
 </div>
<button type="button" onclick='add_field_row();' ">Add Email</button>
<input type="submit" value="submit" />
</div> 
</form>

$dynamicEmailFields = $_POST['field']
<?php
    foreach($test as $key => $fields) {
       //Here i want to output the field name and value depending on the 
         number of row generated when calling add_field_row() For instance:
         email1: email1@mail.com
         name1: john doe
         email2: email1@mail.com
         name2: john doe

       //With this result from the loop it means that there were 2 rows generated.  
    }
?>

您需要输入数组。这将是最简单的循环：

<input type="text" name="field[0][email]" />
<input type="text" name="field[0][name]" />
<input type="text" name="field[1][email]" />
<input type="text" name="field[1][name]" />

然后：

foreach($_POST['field'] as $field) {
    echo 'email: ' . $field['email'] . '<br/>';
    echo 'name:  ' . $field['name']  . '<br/>';
}
