When converting my site to XHTML, the WordPress plugin “WP GuestMap” posed another little obstacle. It is the plugin that I use on the “Visitors” page to display the world map with the hometowns of all visitors.
\r\nUntil now, I had implemented the map via IFrame. Although the plugin does offer a code snippet for XHTML-conform embedding as an object, it just didn’t work in Firefox: Instead of a map, it displayed – nothing. The code looked as follows:<\/p>\r\n\r\n

\r\n<\/object>\r\n<\/pre>\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n
After I had finally struggled through an article on AListApart.com:”Flash Satay: Embedding Flash While Supporting Standards(AListApart.com)”:http:\/\/www.alistapart.com\/stories\/flashsatay that I had delayed reading for weeks already, I knew what the snag was: It was the attribute classid<\/code> that caused the trouble!<\/p>\r\n\r\n
\r\n
(…) the GUID used in the classid attribute was specific to the browser\u2019s ActiveX configuration. In fact, it was causing Netscape 7 and Mozilla to totally ignore the object.<\/p>\r\n<\/blockquote>\r\n\r\n
To say it clearly: classid<\/code> is only for Internet Explorer, to let it know which player\/program it should use to play back\/display the object. There is, however, another attribute for the very same purpose which is understood by all browsers, namely the type<\/code> attribute. As you can see, the code generated by “WP GuestMap” already contains a type<\/code> declaration. So what’s the point of the totally superfluous classid<\/code>? Hence with it!<\/p>\r\n\r\n
\r\n<\/object>\r\n<\/pre>\r\n\r\n
And now it works in Firefox, too! This little knack is not only helpful with HTML objects like this one, but with all the others as well. Only the type<\/code> statement must be changed. For a Flash object for example, it would have to be type=\"application\/x-shockwave-flash\"<\/code>.<\/p>","protected":false},"excerpt":{"rendered":"When converting my site to XHTML, the WordPress plugin “WP GuestMap” posed another little obstacle.
