i load data in my controller like
$name['name'] = "some text!";
$data['header'] = $this->load->view('header_view', $name, TRUE);
$this->load->view('myView', $data);
and in my view file: myView.php
echo $header;
how can i get data in $name ? thanks
Try:
$data['name'] = "some text!";
$data['header'] = $this->load->view('header_view', $data['name'], TRUE);
$this->load->view('myView', $data);
You can't because when it comes to myView, the header view is allready processed and so data is allready incoroporated into the output string.
The only way is to copy (merge) the contents of $name into $data.
You can get embed data by parsing the content of $data['header'] but it is a really bad solution.
To solve this issue you can generate header and footer along the content inside your controller like that:
$this->load->view('header');
$this->load->view('content');
$this->load->view('footer');
Or you can use a template engine to include header/footer automaticly with the content template.
Infortunately, there is no buildin way to add an header easily in codeigniter. You'll have to come up with your own functions to do that in a helper or library (but you'll not be able to share data between header and content).

after completing a registration formular, when user clicks submit button, I want to first download a pdf and then redirect user to a view. Here is my code :
public function formularSave(Request $request) {
if(!isset($_REQUEST['token'])) {
abort(404);
}
$token = $_REQUEST['token'];
$upd_app = Application::where('token', $token)->update([
'status' => 22
]);
$result = "Registration complete.";
$html .= 'Some test code here
<br>
<p>Date: '.date('d.m.Y H:i:s').'</p>
';
$pdf = PDF::loadHTML($html);
$filename = substr(md5(uniqid().time()), 0, 17) . '.pdf';
$pdf->save(storage_path().'/app/public/uploads/rezolutii/'.$filename);
//code for download pdf HERE!!!!
return view('site.pages.registercomplete', compact('result'));
}
How can I download the pdf, after I create it?
It's impossible on Laravel.
This will not work. Your browser operates on simple requests one goes out one comes in.
There is no way for browser to know if user finished downloading the file and saved it somewhere. The final response from browser if file to be downloaded, nothing can follow that as far as I understand.
Now I'm not sure how that can be handled in javascript but in pure html requests it will not work.

I want to create a PDF in codeigniter using mPDF. My html is passed to the controller using jQuery AJAX. Data is coming to the $html But it is not working. It works fine when html is hard coded. Can any one help me please?
public function pdf($paper='A4')
{
$html = '';
$html = $this->input->POST('content');
$this->load->library('mpdf54/mpdf');
$CI->mpdf = new mPDF('utf-8',$paper);
$mpdf->debug = true;
$this->mpdf->WriteHTML($html);
$this->mpdf->Output();
exit;
}
Try grabbing all the POST vars by using
$html = $this->input->POST();
then echo those out to yourself before moving farther to be sure they are getting set.
public function pdf($paper='A4')
{
print_r($this->input->POST());
return;
}
This of course is only for testing but might help you to see why your $html var isn't getting set. Try that out and give us the results.
Usually, I just set a $feedback var or array and then check for that to display in my views.
However, it occurred to me I should perhaps use flashdata instead.
The problem is sometimes - for say an edit record form, I may simply want to reload the form and display feedback - not redirect. when i use flashdata, it shows but then it shows on the next request as well.
What would be the best practice to use here?
CodeIgniter supports "flashdata", or session data that will only be available for the next server request, and are then automatically cleared.
u use hidden field for that
I would use the validation errors from the Form validation class and load those directly to the view in its 2nd argument.
$this->form_validation->set_error_delimiters('<p>', '</p>');
$content_data = array();
if (!$this->form_validation->run()) {
$content_data['errors'] = validation_errors();
}
$this->load->view('output_page', $content_data);
Then check in your view whether $errors isset.
Controller:
$data['message'] = 'some message you want to see on the form';
$this->load->view('yourView', $data);
View:
if (isset ($message)) : echo $message; endif;

Ive been working with CI and I saw on the website of CI you can load a view as a variable part of the data you send to the "main" view, so, according the site (that says a lot of things, and many are not like they say ...ej pagination and others) i did something like this
$data['menu'] = $this->load->view('menu');
$this->load->view ('home',data);
the result of this is that I get an echo of the menu in the top of the site (before starts my body and all) and where should be its nothing, like if were printed before everything... I have no idea honestly of this problem, did anybody had the same problem before?
Two ways of doing this:
Load it in advance (like you're doing) and pass to the other view
<?php
// the "TRUE" argument tells it to return the content, rather than display it immediately
$data['menu'] = $this->load->view('menu', NULL, TRUE);
$this->load->view ('home', $data);
Load a view "from within" a view:
<?php
// put this in the controller
$this->load->view('home');
// put this in /application/views/home.php
$this->view('menu');
echo 'Other home content';
Create a helper function
function loadView($view,$data = null){
$CI = get_instance();
return $CI->load->view($view,$data);
}
Load the helper in the controller, then use the function in your view to load another one.
<?php
...
echo loadView('secondView',$data); // $data array
...
?>
We are building joomla component. And we use joomla editor in which we insert content.
But there is a problem, because when we add image to editor and save it, it do not add image to database and when we opening this element to edit it again, there is only text in editor, image disappears.
This is how we use it:
$editor =& JFactory::getEditor();
echo $editor->display('text', $this->hello->text, '800', '300', '20', '20');
Maybe there is need to supply aditional parameters to display method?
Problem solved.
The standard way of getting the form data $post = JRequest::get('post'); is not enough in the case of using a editor. This will filter the content, hence losing line breaks and paragraps. So we need to add an extra line to get the editor contents in a raw unfiltered way. This data will be passed to the model to save into the database.
To get HTML form post data you need to get this data in following way
$data = JRequest::getVar( 'editorName', 'defaultValue', 'post', 'string', JREQUEST_ALLOWRAW );
And need to add a javascript for the view(tmpl file)
function submitbutton(action) {
var form = document.adminForm;
switch(action)
{
case 'save':case 'apply':
<?php
$editor =& JFactory::getEditor();
echo $editor->save( 'editorName' );
?>
case 'publish':
case 'unpublish':
case 'cancel':
default:
submitform( action );
}
}
