根据单击的链接更新PHP变量

Question

I display a page with a list of users using this loop:

foreach ($mytaxonomies as $mytaxonomy) :  setup_postdata($mytaxonomy);
  echo $mytaxonomy->name; // print the name of the user
  echo '<a>Send email</a>';
endforeach;

the object $mytaxonomy contains many values like the email of the current user in $mytaxonomy->email

Clicking on the link (Send email) shows a modal overlay with a form to send an email to that user. The form sends the mail to the email address specified in the variable $to but I'm not able to assign the $mytaxonomy->email to that variable (depending on which link was clicked).

I need a thing like

<?php $to = $mytaxonomies[...]->email; ?>

where $mytaxonomies[...]->email changes everytime I click on a different user (because obviously each user have a different email).

EDIT: $mytaxonomies is the array that containes all the users with their infos

print_r($mytaxonomies);

Array
(
    [0] => stdClass Object
        (
            [term_id] => 4
            [name] => John Doe
            [slug] => john-doe
            [email] => [e-mail]
            [age] => ...
            [phone] => ...
        )

    [1] => stdClass Object
        (
            [term_id] => 5
            [name] => Jane Doe
            [slug] => jane-doe
            [email] => [e-mail]
            [age] => ...
            [phone] => ...
        )

    ...
)

Send the e-mail using ajax. Or in another page. You can't set a php variable in a page after the page is loaded.

Ajax example:

$(document).on('click', 'a', function(){
  var data = 'mail=' + $(this).prop('href');
  $.ajax({
    type: 'POST',
    data: data,
    url: 'sendmail.php',
    success: function(){
      alert('mail sent');
    }
  )};
)};

PHP:

<?
foreach ($mytaxonomies as $mytaxonomy) :  setup_postdata($mytaxonomy);
  echo $mytaxonomy->name; // print the name of the user
  echo "<a href='{$mytaxonomy->email}'>Send email</a>";
endforeach;
?>

In sendmail.php you can get the variable mail with POST example: $to = $_POST["mail"];

The HTML form:

<form id="myform" style="display:none" action="sendmail.php">
 ...
 <input name="to">
 <input name="from">
 ...
</form>

The jquery:

$(document).on("click", "a", function(){
  var mail = $(this).prop("href");
  $("#myform").show();
  $('#myform input[name="to"]').val(mail);
});

You will no longer need ajax. the form will send you to sendmail.php. Note: "..." are the rest of your form :)
