I want to populate select option from loop
$form['vote']['selected'] = array(
'#type' => 'select',
'#title' => 'Select',
'#name' => 'name',
);
foreach($loop as $row)
$form['vote']['selected']['#options'] = array($row->id => $row->name);
}
return $form;
Need some help?
This is the standard way to do it:
$options = array();
foreach($loop as $row)
$options[$row->id] = $row->name;
}
$form['vote']['selected'] = array(
'#type' => 'select',
'#title' => 'Select',
'#name' => 'name',
'#options' => $options
);
You might also look at the fetchAllKeyed method of the database query which is a handy shortcut to get data from the database into a keyed array suitable for select lists:
$options = db_query('SELECT id, name FROM {table}')->fetchAllKeyed();
The above will produce exactly the same as the foreach loop above.

I created a select in Typo3 TCA, it's looks like this:
'company_address' => array(
'exclude' => 1,
'label' => 'Company Address',
'config' => array(
'type' => 'select',
'foreign_table' => 'pages',
'foreign_table_where' => ' AND doktype = 75',
'items' => array(
array('', 0)
),
'maxitems' => 1
)
),
By default value = uid of record, how to change this ?
I need that value = my_column. Is it possible ?
You can use a itemProcFunc to build your select options like you need them to be. In your TCA you change the config:
'company_address' => array(
'config' => array(
'type' => 'select',
'itemsProcFunc' => 'Vendor\\MyExt\\UserFunc\\TcaProcFunc->companyAddressItems'
'maxitems' => 1
)
)
You can implement your custom function then. I'll give you an example
namespace Vendor\MyExt\UserFunc;
class TcaProcFunc
{
/**
* #param array $config
* #return array
*/
public function companyAddressItems($config)
{
$itemList = [];
$rows = $this->getMySpecialDokTypeRowsFromDb();
foreach ($rows as $row) {
$itemList[] = ['Label of the item', $row['my_column']];
}
$config['items'] = $itemList;
return $config;
}
}
Whatever you store in $config['items'] will be the item List in your select box. To make this (untested) example work you have of course implement the method getMySpecialDokTypeRowsFromDb().
I have this managed_file form in a Drupal customized module, with this form a user can upload an image and saved it under sites/default/files.
$form['Background_image'] = array(
'#type' => 'managed_file',
'#title' => t('Image'),
'#progress_message' => t('Please wait...'),
'#progress_indicator' => 'bar',
'#description' => t('Click "Browse..." to select an image to upload.'),
'#required' => TRUE,
///'#upload_validators' => array('file_validate_extensions' => array('jpeg jpg png gif')),
'#upload_location' => 'public://backgroundimage/'
'#default_value' => $this->options['Background image'],
);
how to add a function to get the uploaded file?
I tried this but it didnt work.
$image = file_load($form_state['values']['Background_image']);
You should be able to just create the form element, and then use the $form_state['values'] array to get the fid. like this:
function my_module_form() {
$form = array();
$form['background_image'] = array(
'#type' => 'managed_file',
'#title' => t('Image'),
'#progress_message' => t('Please wait...'),
'#progress_indicator' => 'bar',
'#description' => t('Click "Browse..." to select an image to upload.'),
'#required' => TRUE,
'#upload_location' => 'public://backgroundimage/',
'#default_value' => $this->options['background image'] //fid
);
return $form;
}
function my_module_form_submit($form, &$form_state) {
$file = file_load($form_state['values']['background_image']);
$file->status = FILE_STATUS_PERMANENT;
file_usage_add($file, 'module_name', 'entity_name', $entity_id);
file_save($file);
}
I just wrote that on the fly so I'm sure there are syntax errors :) but that's the idea. If you are not getting the file id from $form_state['values']['background_image'], I would try dying in your submit handler and dumping the contents of $form_state['values']:
function my_module_form_submit($form, &$form_state) {
die(var_dump($form_state['values']['background_image']));
}
That should tell you a few things about whats being returned from your form.
I have a form in Zend Framework 1. when I click on edit button I want to display values from databases in the form. but I don't know how to do it.
This is my form code:
// Add an email element
$this->addElement('text', 'orgname', array(
'required' => true,
'filters' => array('StringTrim'),
'style' => array('width:220px'),
'decorators'=>Array(
'ViewHelper','Errors'
)
));
This is my controller:
public function editclientcompanyAction()
$form = new Application_Form_Companyform();
$form->addform();
$this->view->form = $form;
$request = $this->getRequest();
$editid=$request->getParam('id');
$edit_show = new Application_Model_Clientcompany;
$showdetails = $edit_show->editclient($editid);
$this->view->assign('datas', $showdetails);
How do I display database vlaues in my Zend Form?
There are two cases.
1) Populating form which has fields same like the database table fields : If you have the form which has same fields like the database fields, then you can populate them easily.
First you need to get the data from the database and then call the Zend_Form populate function passing the data as an associative array, where keys will be same like form fields names and values will be values for the form fields, as below in case of your form.
This will be in your controller
$data = array("orgname" => "Value for the field");
$form = new Application_Form_Companyform();
$form->populate($data);
Now send will automatically populate the form field orgname. You dont need to modify your form or set the value field in the addElement.
*2)Setting field value manually: * The second case is to set the value manually. First you will need to modify your form and add a constructor to it. Also in your form class you will need to create a property (if you have multiple fields, then you can create an array property or multiple properties for each field. This will be all up to you.). And then set the value key in the addElement. Your form should look like this
class Application_Form_Companyform extends Zend_Form
{
private $orgname;
public function __contruct($orgname)
{
$this->orgname = $orgname;
//It is required to call the parent contructor, else the form will not work
parent::__contruct();
}
public function init()
{
$this->addElement('text', 'orgname',
array(
'required' => true,
'filters' => array('StringTrim'),
'style' => array('width:220px'),
'decorators'=>Array('ViewHelper','Errors'),
'value'=>$this->orgname
)
));
} //end of init
} //end of form
Now your controller, you will need to instantiate the form object passing the value of the orgname field like below
$form = new Application_Form_Companyform("This is the value for orgname");
And thats it.
I used such methods and it works like a charm. For your requirements, you may need to adjust the above sample code, as i did not checked it, but it will run fine for sure i hope :P
Thank you
Ok in either ZF1 or ZF2 just do this.
// Add an email element
$this->addElement('text', 'orgname',
array(
'required' => true,
'filters' => array('StringTrim'),
'style' => array('width:220px'),
'decorators' => Array('ViewHelper','Errors'),
'value' => $showdetails->orgname
)
));
You might want to test first for null/empty values first though, you could use ternary operators for convenience:
// Add an email element
$this->addElement('text', 'orgname',
array(
'required' => true,
'filters' => array('StringTrim'),
'style' => array('width:220px'),
'decorators' => Array('ViewHelper','Errors'),
'value' => empty($showdetails->orgname)? null : $showdetails->orgname
)
));
Please have a look in my edit function at /var/www/html/zend1app/application/controllers/CountryController.php :
public function editAction() {
$data = $this->getRequest()->getParams();
$id = (int)$data['id'];
$options = array();
$country = $this->getCountryModel()->fetchRow("id=$id");
if(!$country)
{
throw new Exception("Invalid Request Id!");
}
$form = new Application_Form_Country();
$form->addIdElement();
if ($this->getRequest()->isPost()) {
if ($form->isValid($this->getRequest()->getPost())){
$data = new Application_Model_Country();
if($data->save($form->getValues()))
{
$message = array("sucess" => "Country has been updated!");
}
else {
$message = array("danger" => "Country could not be updated!");
}
$this->_helper->FlashMessenger->addMessage($message);
return $this->_helper->redirector('index');
}
}
$options = array (
'id' => $country->id,
'name' => $country->name,
'code' => $country->code
);
$form->populate( $options ); // data binding in the edit form
$this->view->form = $form;
}
and form class at /var/www/html/zend1app/application/forms/Country.php :
class Application_Form_Country extends Zend_Form
{
public function init()
{
// Set the method for the display form to POST
$this->setMethod('post');
// Add an email element
$this->addElement('text', 'name', array(
'label' => 'Enter Country Name:',
'required' => true,
'filters' => array('StringTrim'),
'validators' => array(
array('validator' => 'StringLength', 'options' => array(0, 20))
)
));
// Add the comment element
$this->addElement('text', 'code', array(
'label' => 'Enter Country Code:',
'required' => true,
'validators' => array(
array('validator' => 'StringLength', 'options' => array(0, 20))
)
));
// Add the submit button
$this->addElement('submit', 'submit', array(
'ignore' => true,
'label' => 'Save',
));
// And finally add some CSRF protection
$this->addElement('hash', 'csrf', array(
'ignore' => true,
));
}
public function addIdElement()
{
$this->addElement('hidden', 'id');
}
}

I have a problem making Drupal module .
I created a form for adding into database but i am having no luck with creating form to edit some record here is my problem.
The problem is when i load values into form load from database and change them and then click submit button form refresh before it submit new values. So it updates into database same thing as it was. Here is a code :
function edit_form($form, &$form_state) {
$query = db_select('activity', 'f')
->fields('f')
->condition('IDA', $_GET['edit']);
$thefile = $query->execute();
$title = "";
$desc = "";
$file = "";
$privacy = "";
while($record = $thefile->fetchAssoc())
{
$title = $record['title'];
$desc = $record['description'];ick submit button form refresh before it submit new values. So it updates into database same thing as it was. Here is a good :
function edit_form($form, &$form_state) {
$query = db_select('activity', 'f') ->fields('f') ->co
$file = $record['trainingresource'];
$privacy = $record['privacy'];
}
$form['activity'] = array(
'#type' => 'fieldset',
'#title' => t('Create a new activity'),
'#tree' => TRUE,
);
$form['activity']['title'] = array(
'#type' => 'textfield',
'#title' => t('Title'),
'#description' => t('Please enter the title here.'),
'#value' => t($title),
);
$form['activity']['description'] = array(
'#type' => 'textarea',
'#title' => t('Enter Description'),
'#value' => t($desc),
'#description' => t('Please put description here.'),
);
/* $form['activity']['date'] = array(
'#type' => 'date',
'#title' => t('Enter activity date'),
'#description' => t('Please put activity date in here.'),
); */
$form['activity']['file'] = array(
'#type' => 'file',
'#title' => t('Submit activity file'),
'#value' => t($file),
'#description' => t('Please files in here.'),
);
$form['activity']['security'] = array(
'#type' => 'radios',
'#title' => t('Privacy'),
'#value' => t($privacy),
'#options' => array('True'=>t('True'),'False'=>t('False')),
);
// Description
$form['hidden'] = array('#type' => 'value', '#value' => 'is_it_here');
$form['submit'] = array('#type' => 'submit', '#value' => t('Save'));
return $form;
}
And here is a submit form code:
function edit_form_submit($form, $form_state) {
$idt = $_GET['edit'];
$title = trim($form_state['values']['activity']['title']);
$desc = trim($form_state['values']['activity']['description']);
//$date = trim($form_state['values']['activity']['date']['year']."-".$form_state['values']['activity']['date']['month']."-".$form_state['values']['activity']['date']['day']);
$file = "file";
$privacy = trim($form_state['values']['activity']['security']['#value']);
$nid = db_update('activity') // Table name no longer needs {}
->fields(array(
'title' => $title,
'description' => $desc,
//'date' => $date,
'trainingresource' => $file,
'privacy' => $privacy,
))
->condition('IDA', $idt,'=')
->execute();
drupal_set_message($idt);
drupal_set_message("Added into database");
drupal_goto('activity', array('query'=>array(
'activ'=>$_GET['activ'],
)));
}
If someone have the same problem or know how to solve this problem , please help me .
Thanks in advance.
First of all i would like to point out your example code has been pasted wrongly. I see two declaration of same function edit_form.
Am assuming the first declaration was a wrong paste and continuing to answer this.
The major issue i have seeen in your form declaration is that you are using "#value" to store the a default value. Please use "#default_value".
If you use #value, it ignores the user submitted values.
Read more about use of #value.
Read more about use of #default_value
For example change,
$form['activity']['description'] = array(
'#type' => 'textarea',
'#title' => t('Enter Description'),
'#value' => t($desc),
'#description' => t('Please put description here.'),
);
to
$form['activity']['description'] = array(
'#type' => 'textarea',
'#title' => t('Enter Description'),
'#default_value' => t($desc),
'#description' => t('Please put description here.'),
);
Also i strongly recommend you to check this link which is a module that provides lots of examples to interact with Drupal.
I have a tableselect form that lists several items. When a user selects one or more items, and clicks the edit button, I want a new form to show up that lets them edit the items.
I have the new form structure being generated, but I can't get it to show up after the edit button is clicked.
Currently, nothing seems to happen. I know that the tableselect form is being submitted correctly, and the function to create the edit term form is working correctly. I tested it with drupal_set_message and var export.
So, how do I get the new form to show?
Here is my relevant code:
/**
* Generate form for listing terms
*/
function markit_form_terms_list()
{
$form = array();
$form['terms'] = array(
'#type' => 'fieldset',
'#title' => t('List of Terms'),
);
$header = array(t('Name'), t('ID'), t('SetID'));
$form['terms']['items'] = array(
'#type' => 'tableselect',
'#header' => $header,
'#title' => t('Terms'),
'#options' => markit_get_array_terms(),//drupal_map_assoc($header, 'markit_get_array_terms'),
'#tree' => TRUE,
);
$form['terms']['submit'] = array(
'#type' => 'submit',
'#value' => t('Edit Term'),
'#submit' => array('markit_form_terms_list_submit'),
);
/*$form['terms']['delete'] = array(
'#type' => 'submit',
'#value' => t('Delete Term'),
'#submit' => 'markit_form_terms_delete'
);*/
return $form;
}
/**
* Generate form to edit the terms.
* #param <type> $form
* #param <type> $form_state
* #return string
*/
function markit_form_term_edit($form, $form_state)
{
$newform = array();
$newform['termstoedit'] = array(
'#type' => 'fieldset',
'#title' => t('Edit Term/s'),
);
foreach($form_state['values']['items'] as $row)
{
if($row!=0)//if a row is not selected, it will be 0. So don't select rows equal to 0.
{
$terminfo = markit_get_markterms($row);
drupal_set_message(var_export($terminfo,true));//['term_name']);
drupal_set_message($terminfo[0]['term_name']);
$newform['termstoedit'][$terminfo[0]['term_id']] = array(
'#type' => 'textfield',
'#title' => t('Term:'),
'#default_value' => $terminfo[0]['term_name'],
'#size' => 60,
'#maxlength' => 128,
'#required' => TRUE,
);
}
}
$newform['termstoedit']['submit'] = array(
'#type' => 'submit',
'#value' => t('Edit Term'),
'#submit' => array('markit_form_term_edit_submit'),
);
drupal_set_message(var_export($newform,true));
return $newform;
}
function markit_form_terms_list_submit($form,$form_state)
{
drupal_set_page_content(drupal_build_form('markit_form_term_edit', $form_state));
}
I believe I am not using the correct code in the markit_form_terms_list_submit function. I've tried several different things, but it hasn't worked yet. And the Google searches I've done haven't helped either. I also have searched the Drupal API and Drupal Form API sites extensively.
Anyway, I think that's all the info you might need in order to help me. Thanks in advance!
I believe you may have better luck if you have one form function with differing fields being shown depending on the output.
If you do this you will even be able to use the form ajax methods to auto update your form.
Have a look at this howto to see if you think the approach will work for you.
