php if then question was created by intown

This may be a simple php question.

What would be the proper to code to show a custom field if it exists and if it does not show the page title?

Here are my two blocks of code

Custom Field

Code:

<!-- BOF intro-left block -->
<?php if (isset($this->item->positions['intro-left'])) : ?>
<div class="lineinfo intro-left">
	<?php foreach ($this->item->positions['intro-left'] as $field) : ?>
	<span class="element">
		<?php if ($field->label) : ?>
		<span class="label field_<?php echo $field->name; ?>"><?php echo $field->label; ?></span>
		<?php endif; ?>
		<span class="value field_<?php echo $field->name; ?>"><?php echo $field->display; ?></span>
	<?php endforeach; ?>
	
</div>
<?php endif; ?>
<!-- EOF intro-left block -->

Page Title

Code:

<!-- BOF item title -->
<?php if ($this->params->get('show_title', 1)) : ?>
<h2 class="contentheading flexicontent">
	<?php echo $this->escape($this->item->title); ?>
</h2>
<?php endif; ?>
<!-- EOF item title -->

Just not sure of the syntax to display the page title if no intro-left fields exist.

Thanks!

Thinking about it a little more. Could a statement like this work?

Code:

<?php if (isset($this->item->positions['intro-left'])) : ?>
do nothing
else
<?php echo $this->escape($this->item->title); ?> (show the page title)    

Just need to figure out what the correct code would be.

After some trial and error, I came up with this code which seems to work

Code:

<?php if (isset($this->item->positions['intro-left'])) : ?>

<?php else : ?>
<h2 class="contentheading flexicontent">
   <?php echo $this->escape($this->item->title); ?>
</h2>
<?php endif; ?>

Is there a better way to accomplish my goal?

Thanks!
