There are 2 things I want to achieve on this web page:
1. Preserve visitor input on the form when the form is redisplayed.
2. I want to write validating messages on the right side of the form fields.
 
I need help to figure out how I can achieve both requirements for a textarea box.

<p><label for="emailAddr">Email Address</label> 
<input id="emailAddr" type="text" name="emailAddr" maxlength="51"
value="<?php echo $emailAddr; ?>" />
<?php
	if (array_key_exists('emailAddr', $fmErrors)) {
		echo '<span class="nobr">';
		echo ' ';
		echo $fmErrors['emailAddr'];
		echo '</span>';
		}
?>
</p>
<!-- prayer request --> 
<p><label for="prayerReq">Write Your Prayer Request</label>
<textarea id="prayerReq" name="prayerReq" rows="10" cols="51">
<?php echo $prayerReq; ?></textarea></p>

Hi,

First, you have to tell the page to redirect to itself after submmiting the values.  You can do it using the action paprameter inthe Form tag.

Let's say that your file name is Contact.php.

Please, follow the example in the attached code.

I hope this will help you.


$errorMessage = "";
$error = false;
if (isset($_POST["submit"])) {
  // Insert here your validation code
  // if there is an error set the error variable $error = true
  // and the error Message variables $errorMessage = "My Error Message"
}
 
<form id="submitForm" action="Contact.php" method="POST">
<p><label for="emailAddr">Email Address</label> 
<input id="emailAddr" type="text" name="emailAddr" maxlength="51"
value="<?php echo isset($_POST["emailAddr"])?$_POST["emailAddr"]:""; ?>" />
<?php
        if (array_key_exists('emailAddr', $fmErrors)) {
                echo '<span class="nobr">';
                echo ' ';
                echo $fmErrors['emailAddr'];
                echo '</span>';
                }
?>
</p>
<!-- prayer request --> 
<p><label for="prayerReq">Write Your Prayer Request</label>
<textarea id="prayerReq" name="prayerReq" rows="10" cols="51">
<?php echo  isset($_POST["prayerReq"])?$_POST["prayerReq"]:""; ?></textarea><?php if ($error) { echo $errorMessage }?></p>
<p><input name="submit" type="submit" value="submit"></p>
</form>

Thanks denniscm20. The error message is below the textarea. Is it possible to place the error message to the Right of the textarea? That is where I want it - to the right side of the textarea.

Yeah, it is possible.

The simpliest way to do that is putting the textarea into a table tag
<table><tr><td><label for="prayerReq">Write Your Prayer Request</label></td><td>
<textarea id="prayerReq" name="prayerReq" rows="10" cols="51">
<?php echo  isset($_POST["prayerReq"])?$_POST["prayerReq"]:""; ?></textarea></td><td><?php if ($error) { echo $errorMessage }?></td></tr></table>
