Help adding custom image size

[dsgnr]

Hello,

Not an issue presé. I am trying to add a custom image size to the new loop and can't seem to get the new size to show... it's still just showing the full size image.

Here is what I am trying on my template page: <?php MultiPostThumbnails::the_post_thumbnail( get_post_type(), 'first-portrait-image'), size('portrait-image'); ?>

In this case, the image size is simply 'portrait-image'.

I have looked on the wiki but can't seem to suss it out.

Thank you in advance!

Here's the info on using that function. The size parameter is the 4th one and needs to be an array. So you probably need to use something like:

<?php 
MultiPostThumbnails::the_post_thumbnail(
  get_post_type(),
  'first-portrait-image',
  null,
  'portrait-image' 
);
?>

updated to correct last argument based on comment below from @lunule in case anyone doesn't read that far

Thank you for your quick response… I have put your code in but although is shows an image (the incorrect one, one that isn't even specified in my functions.php file, I also get a media.php error. Here is what I have currently:

Functions.php: new MultiPostThumbnails( array( 'label' => 'First Portrait Image', 'id' => 'first-portrait-image', 'post_type' => 'post' ) );

Index.php: <?php MultiPostThumbnails::the_post_thumbnail( get_post_type(), 'first-portrait-image', null, array('portrait-image' ) ); ?>

The image that appears is 150px square, whereas the actual image I am trying to call is 355x533. The error I get on the front end is: Notice: Undefined offset:

I am sure I am doing something wrong as it's showing a thumbnail that isn't specified anywhere, even in the media section of settings. Everything else I have tried, simply shows the full size image but with no error message.

Thanks!

It looks like your thumbnail registration is incorrect. See the docs for instantiating the class and an example.

If anyone's still confused a little bit: Chris' original code is almost OK. But instead of array -which didn't work for me either- use the single, quoted format name.

Didn't work: array( 'portrait-image' ) Works fine: 'portrait-image'

So the final display code in this case looks like:

<?php 
MultiPostThumbnails::the_post_thumbnail(
  get_post_type(),
  'first-portrait-image',
  null,
  'portrait-image'
);
?>
