Featured Images on thumbnails grey out

Hi!

The first function should work out of the box. But if it doesn’t, you can check if _nelioefi_url is set and, if it is, return that instead:

function penci_get_featured_image_size( $id, $size = 'full' ) {
  $efi_url = get_post_meta( $post_id, '_nelioefi_url', true );
  if ( is_string( $efi_url ) && strlen( $efi_url ) ) {
    return $efi_url;
  }
  // followed by the original code
}

The other function is slightly more complicated, but I don’t think you’ve ever tweaked that. Try with the first one and let us know!

BTW, you can add that tweak in a custom plugin of yours (instead of adding it in your theme’s functions.php file). If you create this custom plugin, you won’t lose your customizations when the theme is updated.

Hi,

Thanks for the reply!

DO I use that code you gave and replace with the first function of the theme code?
I am noob in this but what you mean by custom plugin of mine?

Thanks!

I see. Then create a new file named nelio-penci-support.php with the following content:

    preg_match( '@src="([^"]+)"@', $image_html, $match );
    $src = array_pop( $match );
    return $src;
  }
}

and save it in wp-content/plugins/. This will create a plugin you can enable in your site. Once it’s enabled, this function will “overwrite” the one in your theme.

Hello,

I have tried that but it doesn’t work.

Okay, I add in one more line and it works great.
if ( ! function_exists( 'penci_get_featured_image_size' ) ) {
However, it only works if I set the feature image in my post. However, it doesn’t automatically set feature image by taking the last image of my post. I have like many older entries which I can’t do it one by one.

Is there any solution? It works last time.

Is your theme free? Where can I download it? I need the theme to (try to) find a solution.

Hi,

My theme is not free. It’s Soledad theme (in case you have it). DOes it works with other free themes by mass auto set featured images using the last image of post?

If yes, let me know how I can send it to you.

I was just asking to download a copy.

Okay, I add in one more line and it works great: if ( ! function_exists( 'penci_get_featured_image_size' ) ).

Are you sure about this? I mean, does it only work with the if clause? I’d say it’s unnecessary in the plugin you’ve just created, because of the second part of your message:

However, it only works if I set the feature image in my post. However, it doesn’t automatically set feature image by taking the last image of my post. I have like many older entries which I can’t do it one by one.

That’s entirely possible. I applied a solution that only retrieves manually-set featured images. If you want the plugin to retrieve them automatically, we need to change the first portion of the function:

function penci_get_featured_image_size( $id, $size = 'full' ) {
  // Nelio Tweak.
  if ( class_exists( 'Nelio_Content_External_Featured_Image_Helper' ) ) {
    $aux = Nelio_Content_External_Featured_Image_Helper::instance();
    $efi_url = $aux->get_nelio_featured_image( $id );
    if ( is_string( $efi_url ) && strlen( $efi_url ) ) {
      return $efi_url;
    }
  }

  // Original function code.
  if ( ! has_post_thumbnail( $id ) ) {
    return '';
  } else {
    $image_html = get_the_post_thumbnail( $id, $size );
    preg_match( '@src="([^"]+)"@', $image_html, $match );
    $src = array_pop( $match );
    return $src;
  }
}

Are you sure about this? I mean, does it only work with the if clause?

Somehow, it just deactivate and said its fatal error. I have no idea why when I add this line it works. Okay here’s the code I put in so far, but it gave me fatal error.
Parse error: syntax error, unexpected end of file in …

    return $src;

}

Is there anything wrong with it?

This was the first error before I add that line:
Fatal error: Cannot redeclare penci_get_featured_image_size() (previously declared in /home3/bellaelysium/public_html/wp-content/themes/soledad/functions.php:1047)

I manage to get it to work…again adding that line (No idea why???)

  }

}
}

But hey, really so much thanks for making it work! A+ help there! ??

Oops, I’m sorry, I see where the error is. Right after return $efi_url I missed a closing bracket:

...
  if ( is_string( $efi_url ) && strlen( $efi_url ) ) {
    return $efi_url;
  } // <-- this one was missing!!
}
...

so make sure to include it there and remove one at the end. Then, try to get rid of the if clause once again; I’m still surprised you need it.

Hello!

Yes, I tried doing that too but it still doesn’t work!

It gave this error:
Fatal error: Cannot redeclare penci_get_featured_image_size()

I am surprised too. No idea why though. Let me know if you figure that out as I am curious too!
It still work when I add that missing bracket, together with the if clause.

Hey..it works perfectly fine for now as I just checked everything. Thanks so much! ??
