PHP For loop for $_POST

Question

Sorry for the noob question. But I am stuck here.

This is my HTML form where the user-form div can be cloned to as many as possible. The #submit-form div has some hidden values which are common for all.

HTML -

 <div class="user-form">
    <input type="text" autocomplete="off" name="name[]"  >
    <input type="email"  autocomplete="off" name="mail[]"  >
 </div>

 <div class="user-form">
    <input type="text" autocomplete="off" name="name[]"  >
    <input type="email"  autocomplete="off" name="mail[]"  >
 </div>

 <div id="submit-form">
    <input type='hidden' name='refer_user_id'  value='<?php echo $refer_user_id ?>'>
    <input type='hidden' name='refer_user_email' value='<?php echo  $refer_user_email ?>'>
    <input type="submit"  value="Invite" />
    <input type="button" class="button" id="clonetrigger" value="Clone" />
</div>

I'm using ajax to submit the form. Basically I want to create accounts using the name and email fields. In PHP How do I use foreach to loop through the name and email fields so that I can create unique accounts?

My print_r($_POST); array looks like this.

Array
(
  [name] => Array
    (
        [0] => david
        [1] => Mark
        [2] => cindy
    )

  [mail] => Array
    (
        [0] => [email protected]
        [1] => [email protected]
        [2] => [email protected]
    )

  [refer_user_id] => 2
  [$refer_user_email] => [email protected]
)

Looks like if you used a regular for loop with an index (i.e. not foreach) you can match up the numerical indexes, right? — developerwjk

Create a loop with a number of iterations equal to the number of submitted name/email pairs, then use the loop counter to access the values for each user.

for ($i = 0; $i < count($_POST['name']); $i++) {
{
    $name = $_POST['name'][$i];
    $mail = $_POST['mail'][$i];
    // Process the new user
}

don't count in the loop

go through one of the arrays with a foreach, use the key for the second array.

 foreach($_POST['name'] as $key =>$name ){
    $mail = $_POST[$key];
 }

foreach($_POST['name'] as $key => $val) {
  echo $val
}

foreach($_POST['mail'] as $key => $val) {
  echo $val
}

Easiest way to loop through those elements. You can reference the other elements with $_POST['refer_user_id']. While this works for the purposes of a foreach, the for loop posted above is more efficient, so I'd recommend using it.

You can use array_combine function:

$data = array_combine($_POST['name'],$_POST['mail']);
foreach($data as $name=>$mail){
  print $name;
  //...
}

See array_combine.

You could also use the JavaScript that's auto-generating the form items to give them a name that would result in linking the php object. i.e.

 <div class="user-form">
    <input type="text" autocomplete="off" name="user[1][name]"  />
    <input type="email"  autocomplete="off" name="user[1][mail]"  />
 </div>

 <div class="user-form">
    <input type="text" autocomplete="off" name="user[2][name]"  />
    <input type="email"  autocomplete="off" name="user[2][mail]"  />
 </div>

Then you could loop through the pairs with foreach($_POST['user'] as $key=>$value) etc...
