Question
I try to print a drupal 'select option' element in a form .I think drupal_render
not applying #default_value
.every thing is ok except #default_value
not applied.
where is the problem?anybody know how i can do this?
do #default_value
accept string
value?
this is pseudo of my codes:
function test_menu(){
$items=array();
$items['admin/config/regional/test']=array(
'title' => 'test',
'description' => t('test'),
'page callback' =>'drupal_get_form',
'page arguments' => array('test_function'),
);
$items[]=array();
return $items;
}
function test_function(){
$header = array
(
'test1' => t('test1'),
'test2'=> t('test2'),
);
$a=(1,2,3);
$$options=array();
foreach($a as $i=>$v)
{
$f['type'] = array(
'#type' => 'select',
'#options' => array(1,2,3,4),
'#default_value'=>1,
);
$options += array($name=>array( 'test1' => $v,
'test2'=> drupal_render($f['type']) ,
}
$form['table'] = array
(
'#type' => 'tableselect',
'#header' => $header,
'#options' => $options,
'#multiple' => FALSE
//'#empty' => t('No users found'),
);
$form['submit'] = array
(
'#type' => 'submit',
'#value' => t('Submit'),
);
return $form;
}
I test textfield
but its also not work and not accept #default_value
in drupal_render
$f['test3']=array(
'#type'=>'textfield',
'#title'=>'test3',
'#default_value' =>'aaa',
);
I suppose this is beacuse using drupal_render .anybody have a solution?
La solution
In Drupal_render 's used in drupal_get_form , #default_value not set use must use #value instaed of it.
$f['type'] = array(
'#type' => 'select',
'#options' => drupal_map_assoc(array('1','2','3','4')),
'#value'=> '1',
);
Autres conseils
The following code doesn`t work:
$form['title'] = array(
'#type' => 'select',
'#options' => drupal_map_assoc(array(t('opt1'), t('opt3'), t('opt4'), t('opt5'), t('opt6'))),
'#default_value' => array($default_value_key));
$form['title1'] = array(
'#type' => 'select',
'#options' => drupal_map_assoc(array(t('opt1'), t('opt3'), t('opt4'), t('opt5'), t('opt6'))),
'#default_value' => array($default_value_key));
return $form;
But then i did the following:
$form['group'] = array('#tree' => TRUE);
$form['group']['title'] = array(
'#type' => 'select',
'#options' => drupal_map_assoc(array(t('opt1'), t('opt3'), t('opt4'), t('opt5'), t('opt6'))),
'#default_value' => array($default_value_key));
$form['group']['title1'] = array(
'#type' => 'select',
'#options' => drupal_map_assoc(array(t('opt1'), t('opt3'), t('opt4'), t('opt5'), t('opt6'))),
'#default_value' => array($default_value_key));
return $form;
And default values now works.
I have the same problem. finally, i found one method. As you said, the default_value does not work. So make the default_value fixed as 0. and change the options array, put the default value on the top.
If you look at the example from Drupal's Form API, you'll see that the #options
setting takes a key-value pair array and in the #default_value
, you should specify the key of the default value, not the string value.
Also, according to documentation for the #options
setting, #options
is expecting String values. So your select should be more like:
$f['type'] = array(
'#type' => 'select',
'#options' => drupal_map_assoc(array('1','2','3','4')),
'#default_value'=> '1',
);
