//i want hidden parameters send in my controler/method
suppose my url link Category/category_product_get/id; ?> but i want id; ?> is hide and pass my controller/method
<?php
if($Category):
foreach($Category as $main):
?><a href="<?php echo base_url() ?>Category/category_product_get/<?php echo $main->id; ?><?php endforeach;endif;?>
//this is my controller Category.php
public function category_product_get($id = null) {
echo $id;
}
You can`t hide parameters with url, you can send id using any encryption method like base64_encode().

In Codeigniter, the following code is typically used for a page that has a form. But the first time a user lands on the page and a form validation fails gets routed through the same path.
As this example shows, the flash data will trigger. even if the user just land on the page and have not submit any form yet.
I am trying to echo a new class name to some input field to highlight them if validation fails. but currently it highlights the field on first load as well.
I am aware I can echo a validation_error or form_error. is there a way to echo a generic message that is not tied to a field-name and only after submission fails
// rules and other stuff above
if ($this->form_validation->run() == FALSE){
$this->session->set_flashdata('errorClass',"is-invalid");
$this->load->view('defaultOrFalse');
}else{
$this->load->view('success');
}
//view file
<input class=" <?php $this->session->flashdata('errorClass') ; ?>">
Basically I am trying to get bootstrap 4's input validation to show up
https://getbootstrap.com/docs/4.0/components/forms/#server-side
I don't know your exact setup but you can do logic like the following:
<?php
class Some_controller extends CI_Controller {
// controller/search/{$term}
public function some_method($term = null) {
// where some_field is some field in your form
// that gets posted on submit
if ($this->input->post('some_field')) {
// or if (isset($_POST)) {
if ($this->form_validation->run() == FALSE) {
$this->session->set_flashdata('errorClass', "is-invalid");
$this->load->view('defaultOrFalse');
} else {
$this->load->view('success');
}
} else {
// default view
}
}
}
?>
For your second question:
<h5>Username</h5>
<?php echo form_error('username'); ?>
<input type="text" name="username" value="<?php echo set_value('username'); ?>" size="50" <?php if (!empty(form_error('username'))) { echo "class='error'"; } ?> />
Can also make a helper and use instead of form_error to check if field has error for your class (haven't verified this works but it should).
/**
* Checks if form validation field by name
* has error
*
* #param string $field Name of field
* #return boolean
*/
function field_has_error($field) {
$CI = &get_instance();
$CI->load->library('form_validation');
$arr = $CI->form_validation->error_array();
if (isset($arr[$field])) {
return true;
}
return false;
}
Usage:
<?php if (field_has_error('username')) { echo "class='error'"; } ?> />
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 have a view in which there's a form that manages products (either add new product or -if an id passed- editing an existing one). If an id is passed then the form action should be eg 'admin/product/manage/5', if no id passed then it should be like this 'admin/product/manage'.
<?php echo form_open('admin/product/manage/{optional product id}', array('class' => 'ajax-form')); ?>
I have also created and this route:
$route['admin/product/manage'] = "admin/product/manage";
$route['admin/product/manage/(:num)'] = "admin/product/manage/$1";
How can I make my form action work correctly? is it possible to put inside the action the route somehow??
This is my Controller:
public function manage($id = NULL){
//fetch a single product to edit or create a new one
if (isset($id) === true) {
$data['prod'] = $this->product_model->get($id);
$data['vers'] = $this->product_version_model->get_by('product_id',$id);
} else {
$data['prod'] = $this->product_model->make_new();// this returns $product->product_name = ''; in order to be empty the input field and not throughing errors
}
$this->product_model->save_product();
$this->product_version_model->save_version();
// load the view
$this->layout->view('admin/products/manage', $data);
}
This is my view:
<?php echo form_open('admin/product/manage', array('class' => 'ajax-form')); ?>
<p>
<label for="product_name">Product *</label>
<input type="text" name="product_name" value="<?php echo set_value('product_name', $prod->product_name); ?>" />
<?php echo form_error('product_name'); ?>
</p>
<?php echo form_close() . PHP_EOL; ?>
You need to declare both possible routes in order of importance, so:
$route['admin/product'] = "admin/product/manage";
$route['admin/product/(:num)'] = "admin/product/manage/$1";
From the Codeigniter Docs:
Routes will run in the order they are defined. Higher routes will always take precedence over lower ones.
Edit:
According to the changes you have made to your question I can say the following:
First of all isset() returns boolean only, so you don't need the type check "=== true". isset($id) is sufficient.
In order to have your form action set to the id you need to include it either in a hidden field or in the action itself.
So for example:
$action_id = (isset($id) ? '/'.$id : ''); // Using ternary operators here
echo form_open('admin/product/manage'.$action_id, array('class' => 'ajax-form'));
and add the id to the view data in your controller:
$data['id'] = $id;
As a side note: In order to comply with SoC (Separation of Concerns) you'd prepare all data in your controller (with e.g. models all having their own task) and pass the processed data to the view instead of partially generating data in the view itself.
I am trying to add some form to my component, but I am not shure what naming conventions must be applied to work it correctly.
Currently I have a working form - it displays fields stored in XML file and loads data from database to it. However, when i try to submit this form (edit or add new records), it doesn't work. After pressing submit (save() method) it just redirects me and displays that record was edited successfuly but it wasn't. When I try to edit existing record, after pressing submit nothing happens and when I try to add new record, it just adds empty/blank record.
So I was doing a little debug and discovered, that problem is in the JController::checkEditId() method. It always returns false which means that JControllerForm::save() returns false as well and that's why it doesn't save it correctly. HTML code of form is correct and I can access the data by using global array $_POST.
I suspect that this problem is because of naming conventions in methods loadFormData, getForm of JModelAdmin class. I am not sure how to name that form.
So here is my code related to this problem:
Subcontroller for displaying the form - controllers/slideshowform.php
class SlideshowModelSlideshowForm extends JModelAdmin{
public function getForm($data = array(), $loadData = true){
return $this->loadForm('com_slideshow.slideshowform', 'editform', array('load_data' => $loadData, 'control' => 'jform'));
}
protected function loadFormData(){
$data = JFactory::getApplication()->getUserState('com_slideshow.edit.slideshowform.data', array());
if (empty($data))
{
$data = $this->getItem();
}
return $data;
}
public function getTable($table = "biometricslideshow"){
return parent::getTable($table);
}
}
views/slideshowform/view.html.php
class SlideshowViewSlideshowForm extends JView{
public function display($tmpl = null){
if (count($errors = $this->get('Errors')))
{
JError::raiseError(500, implode('<br />', $errors));
return false;
}
$this->form = $this->get('form');
$this->item = $this->get('item');
JToolBarHelper::save('slideshowform.save');
parent::display();
}
}
views/slideshowform/tmpl/default.php
<?php
defined('_JEXEC') or die('Restricted access');
JHtml::_('behavior.tooltip');
?>
<form method="post" action="<?php echo JRoute::_("index.php?option=com_slideshow&id=".(int) $this->item->id)?>" name="adminForm" id="slideshow-form">
<fieldset class="adminform">
<legend>Edit slide</legend>
<table>
<input type="hidden" name="task" value="">
<?php echo JHtml::_('form.token'); ?>
<?php
foreach($this->form->getFieldset() as $field){
?>
<tr><td><?php echo $field->label ?></td><td><?php echo $field->input ?></td></tr>
<?php
}
?>
</table>
</fieldset>
</form>
Can someone take o look, please?
you have to add controller SlideshowControllerSlideshowForm and code save method. In there you have to validate the form data and call SlideshowModelSlideshowForm->save event, then redirect with success/failure message.
I have this view:
<?php echo form_open(); ?>
<?php echo form_input('username', '', ''); ?>
<?php echo form_submit('submit', 'Submit'); ?>
<?php echo form_close(); ?>
<?php echo validation_errors(); ?>
and this controller method:
function test() {
$username = $this->input->post('username');
$this->form_validation->set_rules($username, 'Username', 'required|min_length[4]');
if ($this->form_validation->run() !== FALSE) {
echo 'Tada!';
}
$this->load->view('test');
}
but when I leave the username field blank, nothing happens. However, if I type in something in it will tell me the field is required. I've downloaded and given CI a fresh install almost ten times now, trying to load with and without different helpers etc. It's becoming really frustrating, please help.
Try using this:
$this->form_validation->set_rules('username', 'Username', 'required|min_length[4]');
The problem lies in the first parameter of set_rules, which is the field name.
The $username you're passing is basically setting the field name to validate as whatever the user puts in the input field. If you were to type 'username' into the input box, you'd see that your form validates.
Change the line
$this->form_validation->set_rules($username, 'Username', 'required|min_length[4]');
to
$this->form_validation->set_rules('username', 'Username', 'required|min_length[4]');
Maybe is the problem of this line
<?php echo form_open(); ?>
If you leave it blank it basically send back to the controller itself and calling the construct and index function only. In this case your function dealing with form processing is "test()"
try this
<?php echo form_open('yourControllerName/test'); ?> //test is the function dealing with
if it is not working try on this
<?php echo form_open('test'); ?>
