使用PHP post方法提交一组复选框值

Question

Im trying to email a list of checkbox values using wp_mail the result of my code IS sending the email

but the value returns as an array.. I understand why, but I am not sure how to breakdown the array, I dont see how I can implement a foreach here.

PHP:

  //checkmarks post variable
       $checks = $_POST['personalization_result'];

  //php mailer variables
       $to = get_option('admin_email');
       $subject = "Someone sent a message from ".get_bloginfo('name');
       $headers = 'From: '. $email . "rn" .

         $sent = wp_mail($to, $subject, $checks, $headers);

HTML:

<form action="<?php the_permalink(); ?>" method="post">
<input type="hidden" name="submitted" value="1">

    <input type="submit">

<li class="option table selected">
    <div class="option-checkbox">
        <input type="hidden" value="0" name="personalization_result[memory_0]">
        <input type="checkbox" value="1" name="personalization_result[memory_0]" id="personalization_result_memory_0" checked="checked">
    </div>
    </div>
</li>

<li class="option table selected">
    <div class="option-checkbox">
        <input type="hidden" value="0" name="personalization_result[memory_1]">
        <input type="checkbox" value="1" name="personalization_result[memory_1]" id="personalization_result_memory_1" checked="checked">
    </div>
    </div>
</li>

</form>

Before you call the wp_mail function, you need to process your $checks variable and turn it into a string, e.g.:

   $checks = $_POST['personalization_result'];
   $checkString = ''
   foreach ($checks as $k=>$v) {
       //some code to build up $checkString
   }

You'd then obviously have to use $checkString instead of $checks in your wp_mail call . . .

Alternatively, if you don't care about the keys, you could do something like:

     $sent = wp_mail($to, $subject, implode("|",$checks), $headers);

Then you'd end up with something like "0|1"
