I want to create a custom form with a few textfields and then use variable_set to save those textfields as variables.

I am not able to save the variable with the code below.

Question: I do not see the drupal message on hitting submit and when I go to the 'variables' table, I do not see the variable 'id_event'. I have tried clearing all caches several times.

Code below is from *.module file of my custom module "mymodule"

    function mymodule_menu() {

     $items['example_form'] = array(
         'title'        =>  'Progress Numbers',
         'description'  =>  'Form to enter variables that will be shown on Progress Update Block on Front Page',
         'page callback'    => 'drupal_get_form',
         'page arguments'   => array('example_form_form1'),
         'access arguments' => array('access administration menu'),


     return $items;

The callback function:

 function example_form_form1($form, &$form_state) {
  $form['id_event'] = array(
    '#type' => 'textfield',
    '#title' => t('Id Event'),
    '#required' => TRUE,
    '#default_value' => variable_get('id_event', 7),

  $form['submit'] = array(
    '#type' => 'submit',
    '#value' => t('Submit'),
  return $form;

Submit Function

function example_form_form1_submit(&$form, &$form_state) {
  variable_set('id_event', $form_state['values']['id_event']);

I have tried the solution and my result was excelent!

function felicitacion_mensaje_form($form, &$form_state) {
$form = array();
$form['felicitacion'] = array(
'#type' => 'textfield',
'#title' => t('Mensaje de felicitacion'),
'#default_value' => variable_get('congrat','Feliz cumpleaños !nombre te deseamos!.'),
'#description'   => t("Some description"),
return $form;
//   return system_settings_form($form);
function felicitacion_mensaje_form_submit(&$form, &$form_state) {
variable_set('congrat', $form_state['values']['felicitacion']);
$id_event = variable_get('congrat', '');

Modify your example_form_form1_submit function as follows

function example_form_form1_submit(&$form, &$form_state) {
  variable_set('id_event', $form_state['values']['id_event']);
  $id_event = variable_get('id_event', '');

Drupal's variable API allows for storage of persistent variables across separate requests.

If you want to set a Drupal variable, you need to use variable_set().


$my_variable = 'very_important_value';          // Here we set a php variable

variable_set('my_variable_name', $my_variable); // Here we store the php variable
                                                // into a Drupal variable

If you want to retrieve the Drupal variable's value, you need to use variable_get().

$saved_value = variable_get('my_variable_name', 'default_value'); // Get the value of the
                                                                  // Drupal variable. If
                                                                  // it does not exist, then
                                                                  // use the second argument

You are seeing the value stored correctly in the database because you are making use of variable_set() correctly. However, when you are trying to retrieve the value, you need to be sure to call variable_get() to retrieve the value and store it into a php variable for further usage.


function example_form_form1_submit(&$form, &$form_state) {

  variable_set('id_event', $form_state['values']['id_event']); // Stores the value

  $saved_value = variable_get('id_event', 'Default');          // Retrieve the stored value.
                                                               // If it is not saved,
                                                               // $saved_value will be set
                                                               // to 'Default'.

I resolved my problem using "system_settings_form($form);" since the solutions above did not work for me. (Will try later and if it works, will post any learnings here).

Following is what worked for me for reference:

My .module file:

function neil_menu() {

$items['admin/settings/neil'] = array(
    'title' => 'Node images',
    'description' => 'Control how to upload node images.',
    'page callback' => 'drupal_get_form',
    'page arguments' => array('neil_admin_settings'),
    'access arguments' => array('administer site configuration'),
    'file' => 'neil.admin.inc',
 return $items;


neil.admin.inc file:

function neil_admin_settings() {
   $form['progress_so_far'] = array(
'#type' => 'textfield',
'#title' => t('Progress So Far'),
'#default_value' => variable_get('progress_so_far', '0'),
'#maxlength' => 255,

return system_settings_form($form);
