Question

Hi sorry about my bad terminology.

Im using drupal

Im using hook form alter and hook form submit to alter data recorded in the sql table.

this is the code

<?php
function mymodule_form_alter(&$form, $form_state, $form_id) {
  switch ($form_id) {
case 'form_id':
 $form['#submit'][] = 'mymodule_form_submit';
  break;
  }
}

function mymodule_form_submit($form, &$form_state) {

$input = db_result(db_query('SELECT MAX(values) FROM {table} WHERE nid = %d', $fid));
$input10 = (($input) ? $input : 0) + 10;
$submit_record = array(
    'nid' => $form_state['values']['nid'],
    'uid' => $user->uid,
    'time' => time(),
    'amount' => $input10,
  );

drupal_write_record('uc_auction_bids', $submit_record);

drupal_set_message(t('Saved %title.', array('%title' => ($input10 submitted))));

}

however, the original values are also being submitted, so im not altering the submit part, just the form. then my submit code and the original is being submitted. So 2 sets of values are being sent to my database.

How can I prevent the original set of values being sent?

Thanks for any help

Answer 1

By doing the following

$form['#submit'][] = 'mymodule_form_submit';

You are adding your submit handler, and not replacing the default submit handler. If you want to replace the default submit handler you should try

$form['#submit'][0] = 'mymodule_form_submit';
