Hooking into $->find() query parsing function/object

[Adam Kiss]

Hey Ryan,

I'd like to use Processwire's query parsing functions (or object implementation), which are already implemented to parse module's settings, and parse something else.

So what do I need to do, if I have string like

customthing=1|2|3, anotherstuff=1

and I would like to receive object (or array) with customthing and anotherstuff as keys and the rest like their values?

Thanks

Adam you want to use the Selectors class. Try running this example, which should answer a lot of questions:

$str = "a=1|2|3, b<=1, c*=xyz|some, d>10, e|f=something, g!=nothing";
$selectors = new Selectors($str); 

$tests = array('0', '1', '3', '9', '15', 'Adam', 'abcdefghijklmnoprstuvwxyz', 'something', 'nothing');

echo "<ul>";
foreach($selectors as $s) {

   echo "<li>" . $s; 
   echo " (" . $s->field . $s->operator . $s->value . ")"; 
   echo "<ul>";

   foreach($tests as $test) {
       $matches = $s->matches($test) ? "<strong>Matches</strong>" : "Does not match";
       echo "<li>$matches: $test</li>";
   }

   echo "</ul></li>";
}
echo "</ul>";
