Upgrade for 1.8?

[nier3]

Hi, sorry, it was me being a noob question. Upgraded to 1.8 (reinstalled and reuploaded all 1.8 forum files) and all is fine, sorry.

Xthreads seems works very well all ok for this.

A question: how can I do to work this code? If a Thread Field is empty then appears another image:

PHP Code:

<if ($GLOBALS['threadfields']['portalimg']['url']['value']) == " " then> <a href="{$GLOBALS['threadfields']['link']}" target="_blank"><img src="http://img.bitpixels.com/getthumbnail?code=71632&size=200&url={$GLOBALS['threadfields']['link']}" /></a> <else> <img src="{$GLOBALS['threadfields']['portalimg']['url']}/thumb400x400" width="{$GLOBALS['threadfields']['portalimg']['thumbs']['400x400']['w']}" height="{$GLOBALS['threadfields']['portalimg']['thumbs']['400x400']['h']}" alt="{$thread['subject']}" /> </if>

---

- If "portalimg" Thread Field is blank (user no added image) then to use thumbnails from bitpixels;
else
- To use "portalimg" Thread Field (if user uploads an image  with xthreads thread field)


But error in showthread:

Thank you very much, sorry for English
