Flash Keyword Search Module for DGS Search
As I stated before, the reason I liked DGS Search was its modular capabilities. I've included with the attached zip a flash.php This file is to be placed in your ../dgssearch/lib/display/ directory. It is used to send the variables back to Flash.
/*
** flash.php written by James Greenhalgh
** used for keyword search in flash
*/
function flash($retVal, $q, $r, $o, $s, $timer) {
global $config;
$size = ($s < 1) ? count($retVal) : $s;
$dispR = ($r == $config["maxResults"]) ? 0 : $r;
if ($size > 0) {
$i = 0;
reset($retVal);
while (list(, $match) = each($retVal)) {
$i++;
if ($i <= $o)
continue;
if ($i > $o + $r)
break;
$question = $match["link"];
$id = $match["url"];
printf("&link$i=$id&word$i=$question");
}
}
printf("&linksLoaded=yes");
return true;
}
?>
This PHP script gets executed when you click on the Ask Button, it is loaded in the ActionScripting of the Ask Button.
I'm not going to get into explaining every line step by step, but the most important one is this line:
printf("&link$i=$id&word$i=$question");
This is the line that gets output during each successful query match. So if the keyword the user entered
matches the keyword on your db, it sends something along the lines of:
&link1=16&word1=What is your favourite colour?
The "16" in this example is very important. This is the keywords record id, this allows for faster returns
of the answer.
In the case where more than one record exists for that keyword (take for example someone types 'service'
it may return a listing for every service you provide) this is what the output would be like:
&link1=16&word1=Tell me more about your web design
&link2=57&word2=Where can I find your portfolio?
&link3=84&word3=What are the prices for your services
