manual-tb.php?tb_url=<$MTEntryTrackbackLink encode_url="1"$>
&tb_title=<$MTEntryTitle encode_url="1"$>
&tb_entry_url=<$MTEntryLink encode_url="1"$>">Manual Trackback
Note, this whole example should be one line. No spaces can occur within the
href attribute in a link. Also, the encode_url="1" attribute must used to
for the link to work properly and to have valid HTML.
The advantage of the POST method is that the variables are hidden to the
visitor. The disadvantage is that a HTML form is required with a submit
button. Here is an example using forms and the POST method:
This script is embedded within a simple XHTML 1.0 Transitional document. Some
simple CSS styling has been applied. The following CSS classes are employed
within this script:
p.rule = a horizontal separator after introduction text
div.error = formatting for error messages
p.ping = final message if ping was successful or not
This script can be used as a stand-alone document, or as a Movable Type
template. The filename of this script can be renamed to anything. Also,
this script can be placed in any directory. In either case, set the two global
variables near the beginning of the script. Just be sure that your GET URL
or POST action reflect the filename and directory changes. (Don't forget to
modify the URL to Snoopy.class.inc if needed.)
This script was inspired by Adam Kalsey's SimpleTrack (http://kalsey.com/).
This script would have been impractical or un-user-friendly if it was not
for the clue to use the Snoopy php class.
Please feel free to use, copy and/or modify this script for your needs. You
are not required to place my name or link to my website within this script,
but the acknowledgement would be greatly appreciated. Note also that I am not
responsible for any positive or negative effects of this script.
Happy coding... */
