I want to show error on my view but when i submit register-designer and after validation redirect to main view and there i want to display error this is not working how should i solve this.
My Controller:
public function designer_basic()
{
if($this->form_validation->run('as_designer')==true){
echo "good";
}else{
return redirect('Designers/as_designer');
}
}
My View is:
<div class="container">
<div class="col-12">
<?php if(!empty(validation_errors())){?>
<div class="row">
<div class="col-5">
<?php echo validation_errors();?>
</div>
</div>
<?php }?>
You should set rules to validate post values in controller like this
$this->form_validation->set_rules('as_designer', 'Designer', 'required');
Check the documentation of Codeigniter
You should set rules to the controller like this :
$this->load->library('form_validation');
$this->form_validation->set_rules('as_designer', 'Designer', 'required');
if ($this->form_validation->run() == false) {
......
} else {
......
}
I hope it's working fine for you.

I'm trying to change the URL parameter from the row ID to the NAME of the article. here is my code
Controllers
public function view($id=0)
{
if( !isset($id) || !is_numeric($id) ) {
redirect(base_url());
}
$tot = $this->Model_service->service_check($id);
if(!$tot) {
redirect(base_url());
}
and the view is
<?php
foreach ($services as $row) {
?>
<div class="col-lg-4 col-md-6">
<div class="services-item effect-item">
<a href="<?php echo base_url(); ?>service/<?php echo $row['name']; ?>" class="image-effect">
<div class="services-photo" style="background-image: url(<?php echo base_url(); ?>public/uploads/<?php echo $row['photo']; ?>)"></div>
</a>
<div class="services-text">
<h3><?php echo $row['name']; ?></h3>

<?php echo nl2br($row['short_description']); ?>
</p>
<div class="button-bn">
<?php echo READ_MORE; ?> <i class="fa fa-chevron-circle-right"></i>
please help me with the most simplified answer thank you
Yo need to change your article view function in controller. Lookup article name instead of id. But name might contains spaces which is not URL friendly so using concept of slug will solve this.
public function view($slug='')
{
if($slug == '') {
redirect(base_url());
}
$tot = $this->Model_service->find_service_by_slug($slug);
if(!$tot) {
redirect(base_url());
}
Reference link for concept of slug is https://codeigniter.com/user_guide/tutorial/news_section.html
I am new in Codeigniter and I need to show success and error message after insert data's in database.
How can I show the message in the view page?
This is my coding:
Model
function addnewproducts($data)
{
if($data['product_name']!="" && $data['product_qty']!="" && $data['product_price']!="" && $data['date']!="")
{
$res=$this->db->insert('product_list',$data);
return $this->db->insert_id();
}
else
{
return false;
}
}
Controller
function addnewproduct()
{
$this->load->model('products');
$data['product_name'] = trim(strip_tags(addslashes($this->input->post('product_name'))));
$data['product_qty'] = trim(strip_tags(addslashes($this->input->post('product_qty'))));
$data['product_price'] = trim(strip_tags(addslashes($this->input->post('product_price'))));
$data['datetime']=date('d-m-Y');
$res = $this->products->addnewproducts($data);
if($res==true)
{
$data['success'] = 'Successful';
$this->load->view('addproduct',$data);
}
}
View
<p><?php echo $success; ?></p>
There are many ways but below is which i recommend:
Set temp session in controller on success or error:
$res = $this->products->addnewproducts($data);
if($res==true)
{
$this->session->set_flashdata('success', "SUCCESS_MESSAGE_HERE");
}else{
$this->session->set_flashdata('error', "ERROR_MESSAGE_HERE");
}
In View you can display flashdata as below:
echo $this->session->flashdata('success');
or
echo $this->session->flashdata('error');
Source : Codeigniter official website https://codeigniter.com/userguide3/libraries/sessions.html
I appreciate that you got your answer but I think flash data is bit old now, as we can use bootstrap to alert if any error and that looks good to on web page.
In controller
$res = $this->products->addnewproducts($data);
if($res==true)
{
$this->session->set_flashdata('true', 'write_the_message_you_want');
}
else
{
$this->session->set_flashdata('err', "write_the_message_you_want");
}
In View
<?php
if($this->session->flashdata('true')){
?>
<div class="alert alert-success">
<?php echo $this->session->flashdata('true'); ?>
<?php
} else if($this->session->flashdata('err')){
?>
<div class = "alert alert-success">
<?php echo $this->session->flashdata('err'); ?>
</div>
<?php } ?>
Controller:
function addnewproduct()
{
$this->load->model('products');
$data['product_name'] = trim(strip_tags(addslashes($this->input->post('product_name'))));
$data['product_qty'] = trim(strip_tags(addslashes($this->input->post('product_qty'))));
$data['product_price'] = trim(strip_tags(addslashes($this->input->post('product_price'))));
$data['datetime']=date('d-m-Y');
if($this->products->addnewproducts($data));
{
$this->session->set_flashdata('Successfully','Product is Successfully Inserted');
}
else
{
$this->session->set_flashdata('Successfully','Failed To
inserted Product');
}
// redirect page were u want to show this massage.
redirect('Controller/Fucntion_name','refresh');
}// close function
view :
On Redirect Page write This code top of Form
<?php if($responce = $this->session->flashdata('Successfully')): ?>
<div class="box-header">
<div class="col-lg-6">
<div class="alert alert-success"><?php echo $responce;?></div>
</div>
</div>
<?php endif;?>
I want to validate three radio button inputs using codeigniter form validation rule:
HTML Page
<form action="<?php echo base_url('register')" ?> method="POST">
<input type="radio" name="cars" value="BMW">
<input type="radio" name="cars" value="Ferrari">
<input type="radio" name="cars" value="Jaguar">
<input type="submit" name="submitter">
</form>
Controller
public function register()
{
$this->form_validation->set_rules('cars', 'Cars', 'required');
if($this->form_validation->run() == TRUE)
{
i know what to do here
}
else
{
i know what to do here
}
}
How to do form validation in codeigniter for radio button in my case ?
Load library for form validation and other helpers in application/config/autoload.php
$autoload['libraries'] = array('form_validation');
$autoload['helper'] = array('form', 'url');
In your controller
public function register()
{
$this->form_validation->set_rules('cars', 'Cars', 'required');
if($this->form_validation->run() == TRUE)
{
echo "success";
}
else
{
$this->load->view('welcome_message');
}
}
In your view file use below code for printing validation errors
<?php echo validation_errors(); ?>
To show form error use form_error() function and to show all error use <?php echo validation_errors(); ?>
HTML PAGE
<form action="<?php echo base_url('register'); ?>" method="POST">
<?php echo form_error('cars'); ?>
<input type="radio" name="cars" value="BMW">
<input type="radio" name="cars" value="Ferrari">
<input type="radio" name="cars" value="Jaguar">
<input type="submit" name="submitter">
</form>
Controller
public function register(){
$this->load->helper(array('form', 'url'));
$this->load->library('form_validation');
$this->form_validation->set_rules('cars', 'Cars', 'required');
if($this->form_validation->run() == TRUE)
{
echo "i know what to do here"; //die;
}
else
{
echo "i know what to do here"; //die;
}
$this->load->view('welcome_message'); // your html view page
}
I think you are looking for in_list validation as an addition to required that has been mentioned by the others.
$this->form_validation->set_rules('cars', 'Cars', 'required|in_list[BMW,Ferrari,Jaguar]');
Also, as a self-reminder, since it took me 1 year to know about this.
I have a page written in codeigniter framework.
Now I want to add a button to page (eg 'show more') that will get data with 'ajax.php' from the database and display them on the site, but I do not want it separately connect to the database and then get the results, just want to be able to collect data (in ajax.php) as well as in codeigniter controllers (using models)...
Hope you understand me :)
Here you go just add view more button and call this js and ajax function..This is code i have used please see it and use it as per your requirment
$('.more').live("click",function()
{
var this_tag = $(this);
var ID = $(this).attr("id");
if(ID)
{
$("ol#updates").addClass('tiny-loader');
this_tag.html('Loading.....');
$.post(siteUrl+"ajax/ajax_more",{lastmsg:ID,restid:$(this_tag).data("restid")},function(html){
$("ol#updates").removeClass('tiny-loader');
$("ol#updates").append(html);
$("#more"+ID).remove();// removing old view-more button
});
}
else
{
this_tag.fadeOut('slow');// no results
}
return false;
});
code in ajax file
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Ajax_more extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->model('general_model');
$this->limit =REVIEW_DETAIL;
}
public function index($offset = 0)
{
$lastmsg=$this->input->post('lastmsg');
$rest_id=$this->input->post('restid');
$value=('reviews.*,usermaster.Name as User');
$joins = array
(
array
(
'table' => 'tk_usermaster',
'condition' => 'usermaster.Id = reviews.UserId',
'jointype' => 'leftouter'
),
);
$this->results = $this->general_model->get_joinlist('reviews',$value,$joins,array('reviews.Status'=>'Enable','reviews.RestaurantId'=>$rest_id,'reviews.Id <'=>$lastmsg),'reviews.Id','desc',$this->limit,$offset);
$data['list_review']= $this->results['results'];
?>
<?php foreach ($data['list_review'] as $row): ?>
<div class="user_reviews_data" >
<div class="width-20 float-left">
<span class="padleft-10"><?php echo $row->User; ?> </span>
<br/>
<span class="padleft-10 "><div class="rateit" data-rateit-value="<?php echo $row->Rating;?>" data-rateit-ispreset="true" data-rateit-readonly="true"></div></span>
<div class="muted padleft-10 float-left"><small><?php echo date('dS M Y' ,strtotime($row->CreatedDate)); ?></small></div>
</div>
<div class="width-80 float-left"><?php echo $row->Feedback;?></div>
<span class="report_span">Report this Feedback <img src="<?php echo base_url();?>themes/images/FLAG_GREY.png"></span>
</div>
<?php
$msg_id = $row->Id;
endforeach; ?>
</div>
<div id="more<?php echo #$msg_id; ?>" class="btn-container center_text morebox">
View More
</div>
<?php
}
}
i have 4 dropdownlist, 1 dropdownlist as master to control 3 dropdownlist other, this my sample code for master dropdownlist.
<div class="row">
<?php echo $form->labelEx($truck,'Truck'); ?>
<?php echo CHtml::dropDownList('idt',$truck->idt,CHtml::listData(Truck::model()->findAll(),'idt','number'),
array(
'value'=>'1',
'ajax' => array(
'type'=>'POST',
'url'=>CController::createUrl('FindTruck'),
'data'=>array('idt'=>'js:this.value'),
'dataType'=>'html',
))); ?>
</div>
<div class="row">
<?php echo $form->labelEx($employee,'Driver'); ?>
<?php echo CHtml::dropDownList('driver','$variable',CHtml::listData(Employe::model()->findAll(),'ide','name')); ?>
</div>
This My js setDriver
function setDriver(name,value){
document.getElementById(name).value = value
}
and this my controller
public function actionFindTruck() {
echo "<script>setDriver('driver',3);</script>"; // test satatic data
}
the question what code must i write on controller (ActionFindTruck) to change value of $variable above, so if i change Truck, the Driver will be change selected.
Thanks for help.
This is the way I did it, you should be able to change the values to your environment:
public function actionUpdateDropdown()
{
// ajax function to retrieve categories by country:
$lang_id = (!empty($_POST['feature']['language_id'])) ? $_POST['feature']['language_id'] : DEFAULT_LANG_ID;
$data = category::model()->findAll('language_id=:parent_id',
array(':parent_id'=>(int) $lang_id));
$data = CHtml::listData($data,'id','name');
if (!empty($data)) { echo '<option value="">Select Category...</option>'; }
foreach($data as $value=>$name) {
echo CHtml::tag('option',
array('value'=>$value),CHtml::encode($name),true);
}
}
There is a nice discussion of creating dependent drop downs at this URL:
