[Plugin: Multiple Post Thumbnails] Newbe questions

@entartetemuzak

You put the code to call the new MultiPostThumbnails object(s) in your functions.php file. If you don’t have one in your theme, add one and add the code after the opening PHP tag (you can omit the closing PHP tag which is recommended since leaving any whitespace after it will cause errors).

Your code for creating more thumbnails is correct. Just put it in functions.php.

For

<?php if (class_exists('MultiPostThumbnails')
    && MultiPostThumbnails::has_post_thumbnail('post', 'secondary-image')) :
        MultiPostThumbnails::the_post_thumbnail('post', 'secondary-image');
endif; ?>

that would go in your template where you want to display the thumbnail. To add them all you in a template, I’d go with a loop like this to make it a bit easier:

<?php if (class_exists('MultiPostThumbnails') {
	$mpt_images = array(
		'secondary',
		'tertiary',
		'quaternary',
		'quinary',
		'senary',
		'septenary',
		'octonary',
		'nonary',
		'denary',
	);

	foreach ($mpt_images as $mpt_image) {
		if (MultiPostThumbnails::has_post_thumbnail('post', "{$mpt_image}-image")) {
			MultiPostThumbnails::the_post_thumbnail('post', '{$mpt_image}-image');
		}
	}

}
?>

That just puts the size prefixes in an array first to loop over them to save typing (and typos…).

Please, change the code to put in functions.php. When updating the plugin, I got a beautiful “error in line xxx in functions.php” where your code is inserted. Maybe it be better to get a “if function exists”…

The readme was updated last night in v0.5

Hi, can you please have a look at the loop code, because If I use it there seems to be an error, so It doesn’t display.

Here is the code I’m useing to loop thru all images.

<?php if (class_exists('MultiPostThumbnails') {
	$mpt_images = array(
		'1',
		'2',
		'3',
		'4'
	);

	foreach ($mpt_images as $mpt_image) {
		if (MultiPostThumbnails::has_post_thumbnail('post', "secondary-image-{$mpt_image}", $post->ID)) {
			MultiPostThumbnails::the_post_thumbnail('post', secondary-image-'{$mpt_image}', $post->ID 'single-thumb','class=wp-post-image', true);
		}
	}

}
?>

If I paste them all in separate it works.
Thanks for your update in advance.

Regards Marcel

btw Great Plugin!

I think I’m having the same problem as mauricenaef, which is a blank page because of (a suspected) syntax error. I added another ) to the first line:

<?php if (class_exists('MultiPostThumbnails')) {

and the page will then display, but the images aren’t displaying. Going back to:

<?php if (class_exists('MultiPostThumbnails')
&& MultiPostThumbnails::has_post_thumbnail('post', 'secondary-image')) :
MultiPostThumbnails::the_post_thumbnail('post', 'secondary-image', NULL, 'thumbnail'); endif; ?>

for each works fine, but that gets to be a ton of code. It would be nice to have your posted loop work. Unfortunately, I don’t know enough to fix it.

It never fails… once you post something you figure it out minutes later. It was a simple syntax thing. The code below works for me:

Sorry about that formatting.

Hi Eric

Any change we can have a look at the code which worked for you? Both links supplied don’t get to any code and there is no code “below”?

Thanks for your help and best regards Maurice

Ooops. I wasn’t aware of the rules regarding code. Here you go:

I think the keys were, the additional ) in line 1 and using ” instead of ‘ around {$mpt_image}-image.

Hey,

I started using your plugin today and noticed it doesn’t really support using the thumbnail caption… with the normal thumbnail you just do this:

Image: <?php the_post_thumbnail(); ?><br>
Caption: <?php echo get_post(get_post_thumbnail_id())->post_excerpt; ?>

But I ended up having to do this to get the caption from a secondary featured image (note, I’m using this on pages):

$second_thumbnail_id = get_post_meta(get_the_ID(), "page_secondary-image_thumbnail_id", false);
$second_id = $second_thumbnail_id[0];

// The thumbnail caption:
echo get_post($second_id)->post_excerpt;

I guess what’s needed really is for you to make get_post_thumbnail_id() return the post id for the thumbnail if you can.

Btw, love the plugin, made my life easier!
