i have a registration form, which checks for errors before the form is submitted. i was told then to use an if else statement to submit the form on the same page, but i would prefer to have the user go to a confirmation page instead. i have the form submitting to itself to check for errors. any ideas as to how i can do this?

Should be simple enough.

<?php
     if(isset($_POST['submit'])) // when your submit button has name="submit"
     {
          // code for your confirmation page
     }
     else
     {
          // code for your page with the form
     }
?>

here is how i modified the code:

<?php
     if(isset($_POST['register']) && empty($errors)) // when your submit button has name="submit"
     {
         echo "the form will have been submitted!";
     }
     else
     {
         echo "registration form displayed here...";
     }
?>

i want to make sure that the user did not leave any empty fields. but i get " the form will have been submitted" when i submit it with empty fields....

Ahh, so the problem is that you are not checking whether each field is filled, but whether atleast one field is filled. Here's another solution:

<?php
    $valid = true;
    foreach ($errors as &$value)
    {
        if ($value == "")
        {
             $valid = false;
        }
    }
    if(isset($_POST['register']) && $valid)
    {
        echo "the form will have been submitted!";
    }
    else
    {
        echo "registration form displayed here...";
    }
?>

ok, so here is how i modified the code:

<?php

$valid = true;

foreach ($errors as $value)

{
if ($value == "")

{

$valid = false;

}
}

    if(isset($_POST['register']) && $valid)
    {
        echo "the form will have been submitted";
    }
    else
    {
        echo "registration form with errors displayed here...";
    }
?>

it did not like the & sign before the $value. when i submit the form with empty fields, i still get " the form will have been submitted"

here is what i have for the error-checking array:

if (array_key_exists('register',$_POST)){
    // Fields that are on form
    $expected = array('FName', 'LName', 'phone', 'cell', 'street-address', 'state', 'zip', 'email', 'emergecnycontactname', 'pphonenumber', 'relationship', 'aphonenumber');
    // Set required fields
    $required = array('FName', 'LName', 'phone', 'cell', 'street-address', 'state', 'zip', 'email', 'emergencycontactname', 'pphonenumber', 'relationship');
    // Initialize array for errors
    $errors = array();

    foreach ($_POST as $field => $value){
        // Assign to $temp and trim spaces if not array
        $temp = is_array($value) ? $value : trim($value);
        // If field is empty and required, tag onto $errors array
        if (empty($temp) && in_array($field, $required)) {
            array_push($errors, $field);
        }
    }
