MTKeyValues functionality (5 posts)

    Finding that WP supports Custom Fields has convinced me that I should migrate from MT. My old installation makes a lot of use of the MTKeyValues plugin-- a broadly similar concept to Custom Fields.
    ...so what would be nice if the import-mt.php script could interpret these key/value pairs and form Custom Fields for the relevant entries.
    In my MT export, I have various tags in the format:
    EXTENDED BODY:
    (Image information)
    image=markmcmillannews.jpg
    width=165
    height=145
    scale=0.5
    position=right
    comment=Mark McMillan has signed a two year deal at Leeds
    I suppose the interpretation code would be something like:
    if (keyvalue pairs are present) {
    $keyvalue = explode("\n",$extendedentry);
    (skip first line- can't be used for keyvalue pairs)
    foreach ($keyvalue as $line)
    {
    ($key[],$value[]) = explode("=",$line);
    }
    }
    That's the extent of my php knowledge; any takers to complete the fix?
    :-}

    I just found WordPress the other day and I realized that I wanted the exact same thing as you. I used the MTKeyValues plugin and was disappointed that the import-mt.php script just ignored the whole KEYWORDS section. But I guess it's understandable since some people want to do other things with their keywords, like make them into slugs.
    Anyway, I modified the stock import-mt.php script to import key=value type keywords, as well as bare keywords (I convert them into keywords=keyword1 keyword2 keyword3, etc...).
    I've got a patch that you can apply — I'm not sure if it will look good if I post it here, but I'll give it a try. Just copy it into your wp-admin directory and type this: patch import-mt.php import-mt.php.patch

    philipd, do you have an url for that diff?
    I maintain a list of resources for folks moving from mt to wp, and if you don't mind can you please email me the diff, or the patched import-mt.php ?
    the email address is mail @ carthikk dot net
    Thank you. :)

    This patch seems to have been superceded by the current version of WP. Any chance of updating it?
