array_combine可能与不相等数量的元素？ Foreach替代品？

Question

I have a php code that fetch name and email and runs them in a foreach lop so it can send email to a respodent and inputs name and email into a MySQL databas.

My problem is that i can only select all of them but not single once. If I chose only one respodent i get Warning: array_combine(): Both parameters should have an equal number of elements and if i chose all of them it works without a problem. I have tried some solutions as $res = array_combine(array_intersect_key($arr1, $arr2), array_intersect_key($arr2, $arr1));

But it then takes only the names from the top and not the exact name of each email. If I select 2 respodents, lets say Mark and Fredik , Alex and Mark gets inserted inte the database instead of Mark and Frederick. It shows up right email but not the names.

Is there a workaround/fix for this problem?

    <?php
if(isset($_POST['check']) == true)
{

    $subject = trim($_POST['subject']);
    $message = trim($_POST['message']);
    $from = '[e-mail]';
    $i=1;

    $arrayOne = $_POST['check'];
    $arrayTwo = $_POST['fname'];


 $min = min(count($arrayOne), count($arrayTwo));
    $result = array_combine(array_slice($arrayOne, 0, $min), array_slice($arrayTwo, 0, $min));

    foreach($result as $key => $value)
    {

    echo $key. ' '. $value ;

ini_set('display_errors',1);
error_reporting(E_ALL);
require 'class.phpmailer.php';
require 'PHPMailerAutoload.php';

$mail = new PHPMailer;

//$mail->SMTPDebug = 3;                          // Enable verbose debug output

Answer 1

I suggest a more convenient way to build your form so you can access the desired data more easy. Changed part of your form:

<tbody>
<?php  while ($row = mysql_fetch_assoc($getemail)) { ?>
<input type="hidden" value="<?php echo $row['fornamn']; ?>" name="fname[<?php echo $row['email']; ?>]"/>
   <tr>
      <td><input value="<?php echo $row['email']; ?>" type='checkbox' name="check[]" /></td>
      <td >".$row['fornamn']."</td>
      <td >".$row['email']."</td>
   </tr>
<?php } ?>
</tbody>

And use it in your php mailing script like this:

$arrayOne = $_POST['check'];
$arrayTwo = $_POST['fname'];

foreach($arrayOne as $email){

   $fname = $arrayTwo[$email];
   echo $email. ' '. $fname ;
}
