storing variables within foreach loop - php

Question

Hi I currently have some PHP code which will put previously selected timeslots from checkboxes on a previous page into my database, but I'm not sure how to store each one in a variable before I do this, so that I can use them to list the appointment slot's in my e-mail function
At the moment when I try to insert '$key' to my e-mail function it only retains the last selected value...
My code on the first page reads:
<?php
for ($i=0;$i<=31;$i++){ while ($myrow = mysql_fetch_row($result)) {
printf("<tr><td>%s</td><td>%s</td></tr>\n",
$myrow[0]);
}
echo "<td><input type='checkbox' name='$displayTime2' onclick='KeepCount()'></td>";
echo "<td>$pagetime</td>"; ?>
My code at the moment is as follows:
<?php
foreach ($_POST as $key=>$value)
{
echo $key; // show times selected on previous page
mysql_query("INSERT INTO appointment(Patient_ID, Appointment_Date, Appointment_Time
, Practice_ID, Appointment_ID)
VALUES('$patid','$insertdate','$key','$pracid','$apptype')");
}
?>
my mail function is as follows:
$to = "$pemail";
$subject = "Talking Teeth Check Up Booking Confrmation";
$message = "Hello! This e-mail is to confirm your ".$appname." appointment has been
booked for ".$insertdate. " at ".$key." at the ".$pracname." practice";
$from = "talkingteethdentists#talkingteeth.co.uk";
$headers = "From:" . $from;
mail($to,$subject,$message,$headers);
echo "Mail Sent.";

Although the comments above are right, let me help you out.
First off, you need to figure out which checkboxes were selected, so do some IF statements to figure that out on each of these inside of your foreach loop.
Try something like this:
<?php
$savedData = array();
foreach ($_POST as $key=>$value){
$key = mysql_real_escape_string($key);
echo($key. "<br>"); // show times selected on previous page
mysql_query("INSERT INTO appointment(Patient_ID, Appointment_Date, Appointment_Time
, Practice_ID, Appointment_ID)
VALUES('$patid','$insertdate','$key','$pracid','$apptype')");
//To save the variables for later:
$savedData[] = $key;
}
?>
And now you can access all of our KEYs with $savedData[0] .... $savedData[1] ... $savedData[2] .... etc....
So your email function might look like:
foreach($savedData as $time){
$to = "$pemail";
$subject = "Talking Teeth Check Up Booking Confirmation"; //mis-spelled confirmation =)
$message = "Hello! This e-mail is to confirm your ".$appname." appointment has been
booked for ".$insertdate. " at ".$time." at the ".$pracname." practice";
$from = "talkingteethdentists#talkingteeth.co.uk";
$headers = "From:" . $from;
mail($to,$subject,$message,$headers);
echo "Mail Sent.";
}
So this will send out an email for each piece inside $savedData - if that truly is the intent.
