I have a form, automatically generated by a content type. I want to run a form_submit function to input/change some data to get saved in the database.

The content-type already has these fields setup, but I want them to be determined in a form_submit function rather than via user input.

I can get a form submit function, but I don't know how to add to the array of values being submitted without having to write the whole query myself. What variables do I need to grab and how to alter them to do this?

To be more specific.. in the form_alter, this does what I want. $form["field_org_id"]["und"][0]['value']['#default_value'] = $org->id;

But how do I do the equivalent out of site in the form_submit? (this is a content-add form and hoping not to rewrite the entire query)

  1. You have to use hook_form_alter or hook_form_FORM_ID_alter
  2. Add your submit handler to $form['#submit'] like this $form['#submit'][]='my_submit'
  3. And write your code:

    function my_submit($form, &$form_state) { 
      // your code

    isn't there an auto generated form_submit hook name? I was trying that but wasn't working

    this is taken from (api.drupal.org/api/drupal/…) Description: A list of custom submit functions that will be called when the element is submitted. This is usually to add additional submit functions to a form, or to use an alternate function rather than the default form validation function which is the form ID with _submit appended to it.

  • ok i have the hook working either though none of the ways that are supposed to work were working. But my real concern is how to write the function itself.. if I have $form["field_org_id"]["und"][0]['value']['#default_value'] = $org->id; in my form_alter.. how would I implement that same effect in my form_submit

    it seems like you are working with node_submit for this have a look at hook_node_submit

The FORM_FUNCTION_submit() function fires automatically when the form with the prefix generator function is submitted:

function generate_special_form(){ // this function name is "FORM_FUNCTION" above
    $form = array();
    $form['field_org_id'] = array(
        '#type' => 'textfield',
        '#title' => 'Organisation',
    $form['submit'] = array(
        '#type' => 'submit',
        '#value' => 'Submit',
    return $form;

When that function submits it will automatically call the function generate_special_form_submit() with 2 parameters, you can get the submitted values like this:

function generate_special_form_submit($form, &$form_state){
    // Form above was submitted, now lets clean up $form_state['values'], 
    // that's the submitted values in an associative array.
    // And here is the value that was submitted:

It looks like you're trying to modify a form that is generated in core. If that's the case, use hook_form_alter to add the $form['#submit'] value as Jibran outline above.
