forms, $form

By Anonymous (not verified) on 1 Sep 2016 at 16:17 UTC

My form includes several statements from the database, which are generated randomly, ie every time there are new (something like a test). And i need to remember current values, but in &form i can't get the right ones, there are allways updated ones. How can i fix it?

function mudule_form(&$form_state){
.....
$all = array(
'one' => $st[0],
'two' => $st[1],
......
);

$form['questions'] = array(
'#type' => 'checkboxes',
'#title' => t('...'),
'#options' => $all
);
$form['sub_but'] = array(
'#type' => 'submit',
'#value' => t('....')
);
return $form;
}

function module_form_submit($form, &$form_state) {
print_r($form); // i don't see here the statements that i saw before "submit", there are new generated statements
die("\n
DIE");
}

// function mudule_form(&$form_state){ // Incorrect definition

function mudule_form($form, $form_state) { // Although not necessary to pass the arguments but pass for future use.

.....
$all = array(
'one' => $st[0],
'two' => $st[1],
......
);

As far as statements are concerned you need to check code versions of file.

That should be:

That should be:

function module_form($form, &$form_state) {

$form_state needs to be a reference.

It seems you are missing some fairly core concepts of the Drupal Form API. You'd probably be best spending some time doing some research on the Form API and then come back to your form.
