Sending bcc emails only for selected checkbox values - php

Question

I am trying to send the same email only to selected users. I am printing values from table and want to select specific users to send an email.
<form name="unos" action="mail-proizvodi.php" method="post">
<?
echo "<table border='5'>
<tr>
<th> </th>
<th>ID</th>
<th>NAZIV</th>
<th>ADRESA</th>
<th>DRZAVA</th>
<th>GRAD</th>
<th>EMAIL</th>
</tr>";
while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo '<td><input type="checkbox" name="email[]" value="' . $row['ID'] . '"></td>';
echo "<td>" . $row['ID'] . "</td>";
echo "<td>" . $row['NAZIV'] . "</td>";
echo "<td>" . $row['ADRESA'] . "</td>";
echo "<td>" . $row['DRZAVA'] . "</td>";
echo "<td>" . $row['GRAD'] . "</td>";
echo "<td>" . $row['EMAIL'] . "</td>";
echo "</tr>";
}
echo "</table>";
?>
<input type="submit" name="submit" value="submit">
</form>
my mail-proizvodi.php code
$mail=$_POST['email'];
echo "Dzenad catic";
$query= "SELECT `EMAIL` FROM `clanovi` WHERE ID='$mail[0]'";
if(sizeof($mail)>1)
{
for($i=1; $i<sizeof($mail); $i++)
{
$query.=" OR ID = '$mail[$i]' ";
}
}
$result=mysqli_query($con,$query);
while(FALSE!==($row=mysqli_fetch_row($result))) {
$bccfields[] = $row['EMAIL'];
}
echo sprintf("<a href=mailto:test#test.ba?bcc=%s />\n",
urlencode(implode(',',$bccfields)));
echo "Send" ;
Post I am receiving is an array. And when I do var_dump($mail) I get
array
0 => string '20' (length=2)
1 => string '30' (length=2)
Any help or advice is appreciated. Thanks in advance.

I am posting solution for the problem I had in case someone else face similar mistake.
$mail=$_POST['email'];
$query= "SELECT `EMAIL` FROM `clanovi` WHERE ID ='$mail[0]'";
if(sizeof($mail)>1)
{
for($i=1; $i<sizeof($mail); $i++)
{
$query.=" OR ID = '$mail[$i]' ";
}
}
$result=mysql_query($query);
if (!$result) {
echo "Could not successfully run query ($query) from DB: " . mysql_error();
exit;
}
if (mysql_num_rows($result) == 0) {
echo "No rows found, nothing to print so am exiting";
exit;
}
while(FALSE!==($row=mysql_fetch_assoc($result))) {
$bccfields[] = $row['EMAIL'];
}
echo sprintf("<a href=mailto:prodaja#alternativa.ba?bcc=%s />\n",
urlencode(implode(',',$bccfields)));
echo "Send" ;
mysql_free_result($result);
