Hola a todos, quería consultar porque estoy luchando con algo hace ya dos días, y no lo puedo descular.
Cree un modulo, que en el primer paso te pregunta un nombre, en un segundo paso te da para anotar unas fechas, y en el tercer paso se genera una tabla, con los artículos que hay entre esas fechas, lo que yo quería hacer, es que seleccionando esos checkbox(que están en la tabla), cuando pongo save, me retorne los checked. Actualmente, selecciono todos o uno solo, y me llega en el submit como si no hubiese seleccionado ninguno.
<?php
function get_nodes($dateIni,$dateEnd){
$timestampInicio = strtotime($dateIni);
$timestampFin = strtotime($dateEnd);
$result = db_query(
"SELECT nid,title,created FROM {node} WHERE type='Article' AND status=1 AND created BETWEEN $timestampInicio AND $timestampFin ORDER BY created DESC"
);
$nodes = $result->fetchAll();
return $nodes;
}
function newsletter_abz_wizard($form, &$form_state, $no_js_use = FALSE) {
// Provide a wrapper around the entire form, since we'll replace the whole
// thing with each submit.
$form['#prefix'] = '<div id="wizard-form-wrapper">';
$form['#suffix'] = '</div>';
// We want to deal with hierarchical form values.
$form['#tree'] = TRUE;
// $form_state['storage'] has no specific drupal meaning, but it is
// traditional to keep variables for multistep forms there.

Tu solución es tableselect
Si usas drupal_render, los elementos de formulario renderizados no se asocian al formulario donde los estás incrustando. Para eso tenemos tableselect:
function get_nodes($dateIni,$dateEnd){
$timestampInicio = strtotime($dateIni);
$timestampFin = strtotime($dateEnd);
// $result = db_query(
// "SELECT nid,title,created FROM {node} WHERE type='Article' AND status=1 AND created BETWEEN $timestampInicio AND $timestampFin ORDER BY created DESC"
// );
$query = db_select('node', 'n')
->fields('n')
->condition('n.created', $timestampInicio, '>')
->condition('n.created', $timestampFin, '<=')
// ->condition('n.type', 'page', '=')
->orderBy('n.created', 'DESC');
$nodes=$query->execute()
->fetchAll();
// $nodes = $result->fetchAll();
return $nodes;
}
function newsletter_abz_wizard($form, &$form_state, $no_js_use = FALSE) {
// Provide a wrapper around the entire form, since we'll replace the whole
// thing with each submit.
$form['#prefix'] = '<div id="wizard-form-wrapper">';
$form['#suffix'] = '</div>';
// We want to deal with hierarchical form values.
$form['#tree'] = TRUE;
// $form_state['storage'] has no specific drupal meaning, but it is
// traditional to keep variables for multistep forms there.
$step = empty($form_state['storage']['step']) ? 1 : $form_state['storage']['step'];
$form_state['storage']['step'] = $step;
switch ($step) {
case 1:
$form['step1'] = array(
'#type' => 'fieldset',
'#title' => t('Step 1: Campaign Title'),
);
$form['step1']['name'] = array(
'#type' => 'textfield',

Adicionalmente te he corregido la función get_nodes para que no ejecute un db_query, es más conveniente usar db_select que filtra la entrada, si usas db_query debes usar placeholders.
Muchas gracias!
Gracias, ahora si funciona a la perfeccion. desconocia el tableselect! y gracias por lo de la query y el toque a los input de date, quedo mucho mejor ahora!.
Ahora, te molesto con otra consulta y lo termino, si quisiera paginar el resultado, tengo que hacer un desarrollo con la query, o drupal ya trae algo para eso?
Realmente muchas gracias!
Saludos
Paginador
Anteriormente no he realizado paginadores con tableselect debido a que no suele ser común que los usuarios tengan que seleccionar tantos elementos, es más, te recomendaría que lo tuvieras en cuenta, pues un paginador, con selects te va a ser dificil de manejar o le va a ser dificil de manejar a los potenciales usuarios. En mi opinión quizás te resultaría mejor poner filtros en la tabla de forma que puedas filtrar contenidos entre fechas más cortas y limitar la salida de alguna forma.
Una solución muy sencilla sería añadir los filtros de fecha en la misma página que la tabla y un select con las páginas y con el #ajax configurado para que recarguen el div del tableselect.
Si quieres seguir pensando sobre tu solución inicial he encontrado esto:
