Change submitted form values during form validation.

Use this function to change the submitted value of a form element in a form validation function, so that the changed value persists in $form_state through to the submission handlers.

Note that form validation functions are specified in the '#validate' component of the form array (the value of $form['#validate'] is an array of validation function names). If the form does not originate in your module, you can implement hook_form_FORM_ID_alter() to add a validation function to $form['#validate'].


$element The form element that should have its value updated; in most cases you can just pass in the element from the $form array, although the only component that is actually used is '#parents'. If constructing yourself, set $element['#parents'] to be an array giving the path through the form array's keys to the element whose value you want to update. For instance, if you want to update the value of $form['elem1']['elem2'], which should be stored in $form_state['values']['elem1']['elem2'], you would set $element['#parents'] = array('elem1','elem2').

$value The new value for the form element.

$form_state Form state array where the value change should be recorded.
