//define the message to be sent. Each line should be separated with \n
$message = "Congratulations! Your application is approved."; 
//define the headers we want passed. Note that they are separated with \r\n
$headers = "From: bcescholar@yahoo.com\r\nReply-To: bcescholar@yahoo.com";

//define the message to be sent. Each line should be separated with \n
$message = "Sorry your application is revoked."; 
//define the headers we want passed. Note that they are separated with \r\n
$headers = "From: bcescholar@yahoo.com\r\nReply-To: bcescholar@yahoo.com";
//send the email
if (mail($to, $subject, $message, $headers)) {
echo("<p>Congrats!</p>");
} else {
echo("<p>Message delivery failed...</p>");
}
}


} // end of if button pressed

  ?>

 <a href="../index.php"><button type="button"><img src="../../images/back.png"/>Back</button></a>
 </div>
</form> 

my site is sending an email notification to its applicants. If the admin selects the approve from the combobox, it will send automatically an email, otherwise will also send an email of notifying the applicant that his application has been revoked/rejected. But my problem is it's not getting into the APPROVE if ($value == 'Approve') statement..It's always getting into the REVOKE statement. What's wrong with this? Please help. thanks.

Answer 1

The problem is, that $value is only accessable in your foreach($selection as $key => $value) loop, but you try to use it outside of the loop . You could save your values to a temp array to use them afterwards

Example:

$tempArray = array();
foreach($selection as $key => $value)
{
    echo '<option value="' . $key . '"';
    if ($status == $key)
    echo ' selected="selected"';
    echo '>' . $value . '</option>';
    echo ' <br />';
    $tempArray[] = $value;
}

Afterwards access it with:

for($i = 0; $i < count($tempArray[]); $i++) {
   // do what you want sith $tempArray[$i];
}

But I think what you want to do is

if($_POST['status'] == 1) check if "Approve" was selected in your combobox

Answer 2

I have solved it!

since I save the status id of it, I changed to

    if($_POST['status'] == 1)

Thanks to all who helped!
