Trying to create default featured image for blog post in Wordpress, but Code not working

Hi,
I'm building a parent theme from Seamless at Themehybrid. I'm needing to add the functionality of a default image displaying in blog archives when the client doesn't add a featured image and use main post image instead.

I found this code and I'm trying to make it work with the existing code in my theme's template file. When I replace the thumbnail code with this new code I lose the page content. So I'm trying to merge the two and this is what I've come up with, but it's not working either:

In Functions.php:

function selva_main_image() {
$files = get_children('post_parent='.get_the_ID().'&post_type=attachment
&post_mime_type=image&order=desc');
  if($files) :
    $keys = array_reverse(array_keys($files));
    $j=0;
    $num = $keys[$j];
    $image=wp_get_attachment_image($num, 'large', true);
    $imagepieces = explode('"', $image);
    $imagepath = $imagepieces[1];
    $main=wp_get_attachment_url($num);
		$template=get_template_directory();
		$the_title=get_the_title();
    print "<img src='$main' alt='$the_title' class='frame' />";
  endif;
}

Open in new window


In my template file:

<?php if ( ( current_theme_supports( 'get-the-image' ) && (has_post_thumbnail())) {
			 echo get_the_image()
			} else {
		   echo selva_main_image();
		   }
		?>

Where is get-the-image coming from?

Shouldn't it be get_the_image?

You have a code error in your template file code also. If you lose your content when trying the code, that could be why.

Line 2 needs ; (semicolon) at the end:

echo get_the_image();

Adding the semi-colon didn't make much of a difference. Still getting the white screen of death. So I think the issue is bigger than that. jason1178 has provided a clue. I followed the trail and found that 'get-the-image' references a script in an extensions folder. The script has beaucoup options for images, one being the default image I'm looking for!

I set my default image in one of the options and Wow works like a charm. This script is so kickA$$ I'm attaching it below!
