Doctrine supports dynamic binding of parameters to your query, similar to preparing queries. You can use both strings and numbers as placeholders, although both have a slightly different syntax. Binding parameters can simply be achieved as follows:

Doctrine supports dynamic binding of parameters to your query, similar to preparing queries. You can use both strings and numbers as placeholders, although both have a slightly different syntax. Additionally, you must make your choice: Mixing both styles is not allowed. Binding parameters can simply be achieved as follows:

Note that numeric placeholders start with a ? followed by a number while the named placeholders start with a : followed by a string.

If you've got several parameters to bind to your query, you can also use setParameters() instead of setParameter() with the following syntax:
|
||||
|
||||
[php]
|
||||
// $qb instanceof QueryBuilder
|
||||
// $qb instanceof QueryBuilder
|
||||
|
||||
// Query here...
|
||||
$qb->setParameters(array(1 => 'value for ?1', 2 => 'value for ?2', 'whatever' => 'your value for :whatever'));
|
||||
$qb->setParameters(array(1 => 'value for ?1', 2 => 'value for ?2'));
|
||||
|
||||
|
||||
Getting already bound parameters is easy - simply use the abovementioned syntax with "getParameter()" or "getParameters()":
|
||||
|
||||
[php]
|
||||
// $qb instanceof QueryBuilder
|
||||
// $qb instanceof QueryBuilder
|
||||
|
||||
// See example above
|
||||
$params = qb->getParameters(array(1, 2, 'whatever'));
|
||||
// Equivalent to
|
||||
$param = array($qb->getParameter(1), $qb->getParameter(2), $qb->getParameter('whatever'));
|
||||
$params = qb->getParameters(array(1, 2));
|
||||
// Equivalent to
|
||||
$param = array($qb->getParameter(1), $qb->getParameter(2));
|
||||
|
||||
Note: If you try to get a parameter that was not bound yet, getParameter() simply returns NULL.
