Call custom form in a block [duplicate]

Question

I am trying to call a custom form in a block. The form is written in my custom module. I tried different ways to call the form, but not getting the form.

Here is the syntax, I last tried.

$form = drupal_get_form('my_custom_form');
print drupal_render($form); 
//my_custom_form is my form_id

(or)

drupal_render(drupal_get_form('my_custom_form'));

Here is the link I found a similar question, but didn't get the correct solution for my question. Form within a block

Answer 1

You should return your form using drupal_get_form in the content definition of your block. Drupal will do the rest.

For example like this:

function YOURMODULE_block_info()
{
    $blocks = array();

    $blocks['custom_block'] = array(
        'info' => t('Custom block example'),
        'title' => t('Custom block example'),
        'region' => 'content',
        'status' => 1,
    );

    return $blocks;
}

function YOURMODULE_block_view($delta = '')
{
    $block = array();

    switch ($delta) {
        case 'custom_block' :
            $block['content'] = YOURMODULE_block_content();
            break;
    }

    return $block;
}

function YOURMODULE_block_content()
{
    return drupal_get_form('my_custom_form');
}

function my_custom_form($form, &$form_state)
{
    // Build your form

    return $form
}
