I'm trying to dynamically construct a call like this. The only part that changes is Some
SomeQuery::create->findPk($id);
so it could be
WhatQuery::create->findPk($id);
OtherQuery::create->findPk($id);
I tried this, but not sure why it isn't working
$dynamic = "Some";
$tablename = $dynamic."Query::create()";
$$tablename->findPk($id);
If you are using PHP >= 5.3, you can use the following :
$className = 'SomeQuery'; // or another one
$className::create()->findPk($id);
As a reference, see this page of the manual : Scope Resolution Operator
But that's not valid for PHP < 5.3.
I suppose something like this should do the trick :
$className = 'SomeQuery'; // or another one
$created = call_user_func(array($className, 'create'));
$created->findPk($id);
If you have >= PHP 5.3...
$class = 'Some' . 'Query';
$query = $class::create();
$query->findPk($id);
Try with:
$tablename = $dynamic."Query::create";
And if it doesn't work, use call_user_func with array($dynamic."Query", "create").
Good luck!
Factory pattern to be used:
class QueryCreator {
public static function create($queryTypeName) {
if(class_exists($queryTypeName)) {
return $queryTypeName::create();// to use your model.
// I'd use return new $queryTypeName();
}else {
throw Exception("class ".$queryTypeName." does not exist");
}
}
}
usage:
try {
$query = QueryCreator::create("myQuery");
$query->findPK($id);
} catch (Exception $e) {
// whatever// throw it forward or whatever you want to do with it;
}
Make sure that your Query types objects implement the same interface. otherwise you can get errors.
