I'm using Zend Barcode library for my codeigniter project.
previously it work fine. but, now i'm getting blank image instead of barcode
how can i fix this issue?
controller
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Printing extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->library('zend');
}
public function bar_code()
{
$page = 'barcode';
$ch_id = $this->session->user['church_id'];
$data['tbl_data'] = $this->print_model->members_barcode($ch_id);
$data['off_type'] = $off_type;
$data['church_name'] = $this->session->user['church_name'];
$data['main_content'] = 'print/'.$page;
$this->load->view('index', $data);
}
//Barcode Render
public function barcode($data)
{
$this->zend->load('zend/barcode');
Zend_Barcode::render(
'code128',
'image',
array(
'text' => $data,
'barHeight' => 35,
'drawText' => FALSE,
'withQuietZones' => FALSE,
'barWidth' => 100,
));
}
}
view
<img class="br-img" src="<?php echo site_url('printing/barcode/'.$value->mem_tbl_id.$off_type); ?>" alt="">
preview
That function is generate file based data not path file information so you should change view to a link that generated file, because html need path source

I've got on my page several News, to every News we can add comment via form.
So actually I've got 3 News on my index.ctp, and under every News is a Form to comment this particular News. Problem is, when i add comment, data is taken from the last Form on the page.
I don;t really know how to diverse them.
i've red multirecord forms and Multiple Forms per page ( last one is connected to different actions), and i don't figure it out how to manage it.
Second problem is, i can't send $id variable through the form to controller ( $id has true value, i displayed it on index.ctp just to see )
This is my Form
<?php $id = $info['Info']['id']; echo $this->Form->create('Com', array('action'=>'add',$id)); ?>
<?php echo $this->Form->input(__('Com.mail',true),array('class'=>'form-control','field'=>'mail')); ?>
<?php echo $this->Form->input(__('Com.body',true),array('class'=>'form-control')); ?>
<?php echo $this->Form->submit(__('Dodaj komentarz',true),array('class'=>'btn btn-info')); ?>
<?php $this->Form->end(); ?>
and there is my controller ComsController.php
class ComsController extends AppController
{
public $helpers = array('Html','Form','Session');
public $components = array('Session');
public function index()
{
$this->set('com', $this->Com->find('all'));
}
public function add($idd = NULL)
{
if($this->request->is('post'))
{
$this->Com->create();
$this->request->data['Com']['ip'] = $this->request->clientIp();
$this->request->data['Com']['info_id'] = $idd;
if($this->Com->save($this->request->data))
{
$this->Session->setFlash(__('Comment added with success',true),array('class'=>'alert alert-info'));
return $this->redirect(array('controller'=>'Infos','action'=>'index'));
}
$this->Session->setFlash(__('Unable to addd comment',true),array('class'=>'alert alert-info'));
return false;
}
return true;
}
}
you are not closing your forms
<?php echo $this->Form->end(); ?>
instead of
<?php $this->Form->end(); ?>
for the id problem you should write
echo $this->Form->create(
'Com',
array('action'=>'add/'.$id
)
);
or
echo $this->Form->create(
'Com',
array(
'url' => array('action'=>'add', $id)
)
);
I have successfully added my own form (from the same module) into my custom template, but now I wish to load the taxonomy add term form (used by ubercart I think for product categories in the catalog vocab) into my template.
I have gotten this far with my module - filename simpleadmin.module
/**
* #file
* A module to simplify the admin by replacing add/edit node pages
*/
function simpleadmin_menu() {
$items['admin/products/categories/add'] = array(
'title' => 'Add Category',
'page callback' => 'simpleadmin_category_add',
'access arguments' => array('access administration pages'),
'menu_name' => 'menu-store',
);
return $items;
}
function simpleadmin_category_add() {
module_load_include('inc', 'taxonomy', 'taxonomy.admin');
$output = drupal_get_form('taxonomy_form_term');
return theme('simpleadmin_category_add', array('categoryform' => $output));
}
function simpleadmin_theme() {
return array(
'simpleadmin_category_add' => array(
'template' => 'simpleadmin-template',
'variables' => array('categoryform' => NULL),
'render element' => 'form',
),
);
}
?>
And as for the theme file itself - filename simpleadmin-template.tpl.php, only very simple at the moment until I get the form to load into it:
<div>
This is the form template ABOVE the form
</div>
<?php
dpm($categoryform);
print drupal_render($categoryform);
?>
<div>
This is the form template BELOW the form
</div>
Its telling me that it is
Trying to get property of non-object in taxonomy_form_term()
and throwing up an error. Should I be using node_add() and passing the nodetype?
To render a taxonomy term form, the function should be able to know the vocabulary to which it belongs to. Otherwise how would it know which form to show? I think this is the proper way to do it.
module_load_include('inc', 'taxonomy', 'taxonomy.admin');
if ($vocabulary = taxonomy_vocabulary_machine_name_load('vocabulary_name')) {
$form = drupal_get_form('taxonomy_form_term', $vocabulary);
return theme('simpleadmin_category_add', array('categoryform' => $form));
}
To redirect your form use hook_form_alter
function yourmodule_form_alter(&$form, &$form_state, $form_id) {
//get your vocabulary id or use print_r or dpm for proper validation
if($form_id == 'taxonomy_form_term' && $form['#vocabulary']['vid'] = '7' ){
$form['#submit'][] = 'onix_sections_form_submit';
}
}
function yourmodule_form_submit($form, &$form_state) {
$form_state['redirect'] = 'user';
}
I think I have just been working too long and am tired. I have an application using the Zend Framework where I display a list of clubs from a database. I then want the user to be able to click the club and get the id of the club posted to another page to display more info.
Here's the clubs controller:
class ClubsController extends Zend_Controller_Action
{
public function init()
{
}
public function indexAction()
{
$this->view->assign('title', 'Clubs');
$this->view->headTitle($this->view->title, 'PREPEND');
$clubs = new Application_Model_DbTable_Clubs();
$this->view->clubs = $clubs->fetchAll();
}
}
the model:
class Application_Model_DbTable_Clubs extends Zend_Db_Table_Abstract
{
protected $_name = 'clubs';
public function getClub($id) {
$id = (int) $id;
$row = $this->fetchRow('id = ' . $id);
if (!$row) {
throw new Exception("Count not find row $id");
}
return $row->toArray();
}
}
the view:
<table>
<?php foreach($this->clubs as $clubs) : ?>
<tr>
<td><a href=''><?php echo $this->escape($clubs->club_name);?></a></td>
<td><?php echo $this->escape($clubs->rating);?></td>
</tr>
<?php endforeach; ?>
</table>
I think I am just getting confused on how its done with the zend framework..
in your view do this
<?php foreach ($this->clubs as $clubs) : ?>
...
<a href="<?php echo $this->url(array(
'controller' => 'club-description',
'action' => 'index',
'club_id' => $clubs->id
));?>">
...
That way you'll have the club_id param available in index action of your ClubDescription controller. You get it like this $this->getRequest()->getParam('club_id')
An Example:
class ClubsController extends Zend_Controller_Action
{
public function init()
{
}
public function indexAction()
{
$this->view->assign('title', 'Clubs');
$this->view->headTitle($this->view->title, 'PREPEND');
$clubs = new Application_Model_DbTable_Clubs();
$this->view->clubs = $clubs->fetchAll();
}
public function displayAction()
{
//get id param from index.phtml (view)
$id = $this->getRequest()->getParam('id');
//get model and query by $id
$clubs = new Application_Model_DbTable_Clubs();
$club = $clubs->getClub($id);
//assign data from model to view [EDIT](display.phtml)
$this->view->club = $club;
//[EDIT]for debugging and to check what is being returned, will output formatted text to display.phtml
Zend_debug::dump($club, 'Club Data');
}
}
[EDIT]display.phtml
<!-- This is where the variable passed in your action shows up, $this->view->club = $club in your action equates directly to $this->club in your display.phtml -->
<?php echo $this->club->dataColumn ?>
the view index.phtml
<table>
<?php foreach($this->clubs as $clubs) : ?>
<tr>
<!-- need to pass a full url /controller/action/param/, escape() removed for clarity -->
<!-- this method of passing a url is easy to understand -->
<td><a href='/index/display/id/<?php echo $clubs->id; ?>'><?php echo $clubs->club_name;?></a></td>
<td><?php echo $clubs->rating;?></td>
</tr>
<?php endforeach; ?>
an example view using the url() helper
<table>
<?php foreach($this->clubs as $clubs) : ?>
<tr>
<!-- need to pass a full url /controller/action/param/, escape() removed for clarity -->
<!-- The url helper is more correct and less likely to break as the application changes -->
<td><a href='<?php echo $this->url(array(
'controller' => 'index',
'action' => 'display',
'id' => $clubs->id
)); ?>'><?php echo $clubs->club_name;?></a></td>
<td><?php echo $clubs->rating;?></td>
</tr>
<?php endforeach; ?>
</table>
[EDIT]
With the way your current getClub() method in your model is built you may need to access the data using $club['data']. This can be corrected by removing the ->toArray() from the returned value.
If you haven't aleady done so you can activate error messages on screen by adding the following line to your .htaccess file SetEnv APPLICATION_ENV development.
Using the info you have supplied, make sure display.phtml lives at application\views\scripts\club-description\display.phtml(I'm pretty sure this is correct, ZF handles some camel case names in a funny way)
You can put the club ID into the URL that you link to as the href in the view - such as /controllername/club/12 and then fetch that information in the controller with:
$clubId = (int) $this->_getParam('club', false);
The 'false' would be a default value, if there was no parameter given. The (int) is a good practice to make sure you get a number back (or 0, if it was some other non-numeric string).
I have been using normal file upload element to upload files and validate them. But recently, I found out that implementing a Zend_file_tranfer gives much control over the file.
I am searched Everywhere in the internet searching for a simple example to get started with it, but none of them show how they are linked to the element. I dont know where to create the object of Zend_File_Transfer, and how to add it to the element? I basically dont know, how to use it.
Can anyone give me a beginners example of using zend_File_tranfers, in both zend_form and Zend_Controller_Action
In form:
class Application_Form_YourFormName extends Zend_Form
{
public function __construct()
{
parent::__construct($options);
$this->setAction('/index/upload')->setMethod('post');
$this->setAttrib('enctype', 'multipart/form-data');
$upload_file = new Zend_Form_Element_File('new_file');
$new_file->setLabel('File to Upload')->setDestination('./tmp');
$new_file->addValidator('Count', false, 1);
$new_file->addValidator('Size', false, 67108864);
$new_file->addValidator('Extension', false, Array('png', 'jpg'));
$submit = new Zend_Form_Element_Submit('submit');
$submit->setLabel('Upload');
$this->addElements(array($upload_file, $submit));
}
}
In controller:
class Application_Controller_IndexController extends Zend_Controller_Action
{
public function uploadAction()
{
$this->uform = new Application_Form_YourFormName();
$this->uform->new_file->receive();
$file_location = $this->uform->new_file->getFileName();
// .. do the rest...
}
}
When you create your form do something like this in your form:
$image = $this->getElement('image');
//$image = new Zend_Form_Element_File();
$image->setDestination(APPLICATION_PATH. "/../data/images"); //!!!!
$extension = $image->getFileName();
if (!empty($extension))
{
$extension = #explode(".", $extension);
$extension = $extension[count($extension)-1];
$image->addFilter('Rename', sprintf('logo-%s.'.$extension, uniqid(md5(time()), true)));
}
$image
->addValidator('IsImage', false, $estensioni)//doesn't work on WAMPP/XAMPP/LAMPP
->addValidator('Size',array('min' => '10kB', 'max' => '1MB', 'bytestring' => true))//limit to 200k
->addValidator('Extension', false, $estensioni)// only allow images to be uploaded
->addValidator('ImageSize', false, array(
'minwidth' => $img_width_min,
'minheight' => $img_height_min,
'maxwidth' => $img_width_max,
'maxheight' => $img_height_max
)
)
->addValidator('Count', false, 1);// ensure that only 1 file is uploaded
// set the enctype attribute for the form so it can upload files
$this->setAttrib('enctype', 'multipart/form-data');
Then when you submit your form in your controller:
if ($this->_request->isPost() && $form->isValid($_POST)) {
$data = $form->getValues();//also transfers the file

I want to let users upload images from their drives. Searching around the net, here's what I've found :
The form :
class ImageForm extends BaseForm
{
public function configure()
{
parent::setUp();
$this->setWidget('file', new sfWidgetFormInputFileEditable(
array(
'edit_mode'=>false,
'with_delete' => false,
'file_src' => '',
)
));
$this->setValidator('file', new sfValidatorFile(
array(
'max_size' => 500000,
'mime_types' => 'web_images',
'path' => '/web/uploads/assets',
'required' => true
//'validated_file_class' => 'sfValidatedFileCustom'
)
));
}
}
the action :
public function executeAdd(sfWebRequest $request)
{
$this->form = new ImageForm();
if ($request->isMethod('post'))
if ($this->form->isValid())
{
//...what goes here ?
}
}
the template :
<form action="<?php echo url_for('#images_add') ?>" method="POST" enctype="multipart/data">
<?php echo $form['file']->renderError() ?>
<?php echo $form->render(array('file' => array('class' => 'file'))) ?>
<input type="submit" value="envoyer" />
</form>
Symfony doesn't throw any errors, but nothing is transfered. What am I missing ?
Youre missing an impotant part which is binding the the values to the form:
public function executeAdd(sfWebRequest $request)
{
$this->form = new ImageForm();
if ($request->isMethod('post'))
{
// you need to bind the values and files to the submitted form
$this->form->bind(
$request->getParameter($this->form->getName())
$request->getFiles($this->form->getName())
);
// then check if its valid - if it is valid the validator
// should save the file for you
if ($this->form->isValid())
{
// redirect, render a different view, or set a flash message
}
}
}
However, you want to make sure you set the name format for your form so you can grab a the values and files in the fashion... In your configure method you need to call setNameFormat:
public function configure()
{
// other config code
$this->widgetSchema->setNameFormat('image[%s]');
}
Also in configure you dont need to call parent::setUp()... That is called automatically and is actually what invokes the configure method.
LAstly, you ned to have to correct markup - your emissing the form name from your tag:
<form action="<?php echo url_for('#images_add') ?>" name="<?php echo $form->getName() ?>" method="POST" enctype="multipart/data">
Personally I like to use the form object to generate this as well as it looks cleaner to my eyes:
<?php echo $form->renderFormTag(
url_for('#images_add'),
array('method' => 'post') // any other html attriubutes
) ?>
It will work out the encoding and name attributes based on how youve configured the form.
