Learn moremodX::toPlaceholders¶
Sets placeholders from values stored in arrays and objects.
Each recursive level in the $placeholders array adds to the prefix, building an access path using an optional separator.
Syntax¶
API Doc: modX::toPlaceholders()
array toPlaceholders (array|object $subject, [string $prefix = ''], [string $separator = '.'], [boolean $restore = false])
Example¶
Set an array of placeholders and prefix with 'my.' Returns a multi-dimensional array containing up to two elements: 'keys' which always contains an array of placeholder keys that were set, and optionally, if the restore parameter is true, 'restore' containing an array of placeholder values that were overwritten by the method.
$modx->toPlaceholders(array(
'name' => 'John',
'email' => '[email protected]',
),'my');
Example with Nested Placeholders¶
Using nested data as the $placeholders:
$modx->toPlaceholders(array(
'document' => array('pagetitle' => 'My Page')
));
Corresponds to placeholders such as [[+document.pagetitle]]
Note that using a $prefix on nested placeholders adds the $prefix to the front of each key. For example:
$modx->toPlaceholders(
array(
'test' => 'this',
'document' => array('pagetitle' => 'My Page')
), 'tmp'
);
Would have placeholders such as [[+tmp.test]]
and [[+tmp.document.pagetitle]]
