    Hi,

    I am very new to PHP, and am only about three weeks or so into actually learning it. I have constructed a form and it does all work except for two things which hopefully some of you may be able to assist me with.

    1) First, I am try to validate an email address. I have searched the internet, and found the code in which to do it, but I am having issues actually implementing it. I was hoping some of you may be able to assist me and take a look at my code below to see where I am going wrong.

    2) When an error occurs in the form, the user is sent to the formhandler.php which provides them with the errors, however, since my page is a one page portfolio they are redirected to the top of the page, but my form is at the bottom. I used the <meta http-equiv="refresh" content="0; url=index.html"/> code, and it produces the results I want to a certain extent. The problem is, if you try to reload the page, it is sent into a loop of death in which the page continously refreshes itself. I am trying to use the header option but obviously this not working because its in the formhandler.php. I tried the ob_start but could not get it to work either.

    Hopefully someone will be able to shed some light on my dilemmas. Here is the code I am dealing with (I have pasted the entire php section to ensure I didn't leave any small detail out):

    php:


    <?php

    $name = $_POST['realname'] ;
    $email = $_POST['email'] ;
    $message = $_POST['message'] ;
    $errorFlag = false;
    $errorEmail = false;
    $errorName = false;
    $errorMessage = false;

    if (!$name) {$errorFlag = true; $errorName = true;}
    if (!$email) {$errorFlag = true; $errorEmail = true;}
    if (!$message) {$errorFlag = true; $errorMessage = true;}


    if ($errorFlag == true) {

    ?>

    <div id="errorColumn">
    <h4><img src="images/alert.gif" alt="Alert" title="Alert" class="alert"/>An error has occured:</h4>
    <ul class="ulerror">
    <?php header( "Location: formhandler.php#contactnav" ); ?>
    <?php if ($errorName == true) {echo "<li>The following fields are required: Name</li>";} ?>

    <?php if (eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email)) {
    echo "<li>The following fields are required: Valid Email</li>";} ?>

    <?php if ($errorEmail == true) {echo "<li>The following fields are required: Email</li>";} ?>
    <?php if ($errorMessage == true) {echo "<li>The following fields are required: Message</li>";} ?>
    </ul>
    </div>

    <?php } else { header( "Location: formhandler.php#contactnav" ); ?>


    <?php mail( "blank@gmail.com", "Design Form Submission", $message, "From: $name $email" );
    ?>

    <div id="approvedColumn">
    <h4><img src="images/success.gif" alt="Success" title="Success" class="alert"/>Submission successful!</h4>
    <p class="lastpara">Thank you for your form submission. Sit back and relax, your inquiry will be looked into shortly.</p>
    </div>



    <?php } ?>



    Thanks,

    James
