InputfieldForm::isSubmitted() method

Is form submitted and ready to process?

  • Optionally use this method to test if form is submitted before calling processInput().
  • Specify the submit button name to confirm that was the button used to submit.
  • Returns the name of the submit button used when form is submitted, false otherwise.
  • If no arguments specified, requires that the form has one or more InputfieldSubmit fields.
  • Like with processInput(), make sure form is fully built before calling this.
  • If given $submitName argument that corresponds to InputfieldSubmit field then it will also be confirmed that the input value matches the field value prior to submit.
  • If given a $submitName argument that corresponds to some other Inputfield type then only its presence in the input will be confirmed.

Available since version 3.0.205.


if($form->isSubmitted()) {
  // form was submitted

// specify the button name to confirm it was used to submit the form
if($form->isSubmitted('submit_save')) {
  // form is submitted with button named 'submit_save'

// omit button name to have it return button name used to submit
$submit = $form->isSubmitted(true);
if($submit === 'add') {
  // form was submitted with button named 'add'
} else if($submit === 'save') {
  // form submitted with button named 'save'
} else if($submit === false) {
  // form not submitted
} else {
  // submitted using some other button (name in $submit)
