Search Articles

[gnome]

Hi

I need to have a search form linked to my news articles. The fields I need are shown in the attachment

Is this possible in processwire? Could someone give me pointers on how to go about this?

Many thanks!

It is possibile with PW. You just need the user input from the select list and use the selectors listed here to code your own formular processing for customized search form:

A basic search is included in a clean ProcessWire install. You just have to expand the options there.

Once you've got your form, I think it'll be fairly easy to develop this. But your date fields are the only thing that's going to need a little extra work. Since you are asking for just month and year (no day) you'll want to qualify that to the beginning of the first month and the end of the second month. Finding the beginning of the first month is easy since all months start at day 1. There are various ways to find the end of the second month, but there's one way in my example below. Here's how I might perform the query from the API side (written in the browser so may contain typos):

// where we will store our $pages->find selector
$selector = array(); 

// add the search query if present
if($input->get->search) {
 $search = $sanitizer->selectorValue($input->get->search);
 $selector[] = "title|body~=$search";
}

if($input->get->yearFrom && $input->get->monthFrom) {
 // construct date like 2012-12-02 and convert to timestamp
 $dateFrom = strtotime("{$input->get->yearFrom}-{$input->get->monthFrom}-01 00:00:00"); 
 if($dateFrom) $selector[] = "date>=$dateFrom";
}

if($input->get->yearTo && $input->get->monthTo) {
 // do the same for month-to, but find the beginning
 $dateTo = strtotime("{$input->get->yearTo}-{$input->get->monthTo}-01 00:00:00"); 
 // now find the end of dateTo month by adding 1 month and subtracting 1 second 
 if($dateTo) $dateTo = strtotime("+1 MONTH", $dateTo) - 1; 
 if($dateTo) $selector[] = "date<=$dateTo";
}

// determine and validate the max records to show
$limit = (int) $input->get->limit;
if($limit > 50 || $limit < 1) $limit = 10; 
$selector[] = "limit=$limit"; 

// specify the template we are limiting the search to
$selector[] = "template=article";

if(count($selector)) {
 // perform the search
 $selectorString = implode(', ', $selector); 
 $articles = $pages->find($selectorString);
 echo "<h2>Found " . $articles->getTotal() . " articles matching your query.</h2>"; 
 echo $articles->render(); // or however you want to output them
} else {
 echo "<p>No search specified.</p>";
}
