Hi David,
How would I go about showing a limited number of results from a query but then giving the user the option of expanding the results to show all.
For example, a user searches for washing machines and potentially 1000 results are available. Only 5 of those results should be shown, unless the user clicks on a link to show all the results.
I suppose like an expanding menu!
Thanks,
Simon
Hi David,
Thanks for your quick reply!
Is that how the brands etc. at the bottom of this page are expanded?

Thanks,

Hi Simon,
The Google page is expanding by refining the query rather than just opening up more search results...
Cheers,
David.
Hi Simon,
The easiest way to do this would be to add a hidden field to the search form, for example "limit", and set that to the number of items you want returned in the first search. To add this, edit html/searchform.php and add the following code, before the closing form tag...
<input type='hidden' name='limit' value='5' />Then, in search.php, look for the following code (line 89 in the distribution):
$sql .= " LIMIT ".$offset.",".$config_resultsPerPage;...and replace this with:
if (isset($_GET["limit"])){
$sql .= " LIMIT ".intval($_GET["limit"]);
}
else
{
$sql .= " LIMIT ".$offset.",".$config_resultsPerPage;
}
Now all you need is a way to get out of this and re-load to the full result. To do this, just link directly to search.php?q=QUERY, for example:
if (isset($_GET["limit"])){
print "<a href='search.php?q=".urlencode($q)."'>Click here for ALL results...</a>";
}
The obvious place to insert the above code would be immediately BEFORE the following line, near the bottom of search.php:
if (isset($navigation)) require("html/navigation.php");Hope this helps!
Cheers,
David.
