How do I place error messages inside a form with PHP only?

Here is my validation script:

$name = $_POST['name'];
$email = $_POST['email'];
$text = $_POST['text'];
$uploadedfile = $_FILES['uploadedfile'];

if (isset($_POST['submit'])) {

  if ($_POST['name'] != "") {
    $_POST['name'] = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
    if ($_POST['name'] == "") {
      $errors .= 'Please enter a valid name.<br/><br/>';
    }
  } else {
    $errors .= 'enter your name<br/>';
  }

  if ($_POST['email'] != "") {
    $email = filter_var($_POST['email'], FILTER_SANITIZE_EMAIL);
    if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
      $errors .= "$email is <strong>NOT</strong> a valid email address.<br/><br/>";
    }
  } else {
    $errors .= 'enter your email address<br/>';
  }

  if((empty($_POST['text'])) && ($_FILES['uploadedfile']['size'] < 1))
    /*if((empty($_POST['text'])) && (empty($_FILES['uploadedfile'])))*/ {
      $errors .= 'either enter your text or attach a file.<br/><br/>';
    }

  if ($_POST['text'] != "") {
    $text = filter_var($_POST['text'], FILTER_SANITIZE_STRING, FILTER_FLAG_NO_ENCODE_QUOTES);
    if ($_POST['text'] == "") {
      $errors .= 'Please enter a valid text.<br/><br/>';
    }
  }


  if (!$errors) {do some commands}

  else {
    echo '<div style="color: red; font-weight: bold; text-align: center"> The form was not sent. Please <br />' . $errors . '<br/>
      </div>';



  }

After this script comes my HTML with the form:

<form id="form" action="quot_form.php" method="post" enctype="multipart/form-data">

<div class = "left">
<fieldset>
    <legend><h3>Personal information</h3></legend>

        <input type="text" name="name" id="name" value="<?php echo $name?>" />
    </p>    
    <p>
        <label for="company">Company:
        </label>
        <input type="text" name="company" id="company" value="<?php echo $company?>" />
    </p>    
    <p>
        <label for="email">Email<span class = "star">*</span>:
        </label>
        <input type="text" name="email" id="email" value="<?php echo $email?>" />
    </p>

        <label for="phone">Telephone:
        </label>
        <input type="text" name="phone" id="phone" value="<?php echo $phone?>" />
    </p>
    <p>
        <label for="fax">Fax:

        <input type="text" name="fax" id="fax" value="<?php echo $fax?>" />
    </p>

        <div class="fakefile">

                    </div>
                </div>

Currently, the error messages appear outside the page, above it. How do I place them inside the form?

Thank you!

If the HTML is in the same file as that code or if it's included by that code, you can simply move the else portion of your if-statement directly into the HTML

<form>
<?php
   if ($errors) {          
       echo '<div style="color: red; font-weight: bold; text-align: center"> The form was not sent. Please <br />' . $errors . '<br/></div>';
   }
?>
</form>

Not exactly the most elegant solution, but you get the idea.

If the HTML is somewhere else, the same idea applies except you'll have to pass in the value of $errors so it's available.

You have to pass $errors variable to the place where the form is being displayed, eg. some view. It should be echo'ed there, not in the validation code.
