I'm trying to create a simple reporting system, which can output either HTML or export to Excel. I have got it to create a HTML table successfully through a Codeigniter view but I want to know if there's any way I can re-use that view to create the Excel export, rather than doing it manually, as I'll then have to update it in two places every time I want to make a change to the report.
Any advice appreciated.
Thanks.
This seems to be working:
// Load the table view into a variable
$html = $this->load->view('table_view', $data, true);
// Put the html into a temporary file
$tmpfile = time().'.html';
file_put_contents($tmpfile, $html);
// Read the contents of the file into PHPExcel Reader class
$reader = new PHPExcel_Reader_HTML;
$content = $reader->load($tmpfile);
// Pass to writer and output as needed
$objWriter = PHPExcel_IOFactory::createWriter($content, 'Excel2007');
$objWriter->save('excelfile.xlsx');
// Delete temporary file
unlink($tmpfile);

I want to export data tables to PDF.
I'm using Codeigniter Framework, and use dompdf plugin.
I think the code is correct, because it doesn't show any error information when I click the button to export to PDF, the page spends a long time loading, and in the end, it just displays "can't reach the page".
This problem also happens when I try to download files from my local directory.
Here is the code:
actually issue happened when i try to download more number of records
The controller:
$this->load->library('pdf'); // change to pdf_ssl for ssl
$data = array();
$data['result'] = $finaldata;
$data['search_header'] = $search_header;
$html = $this->load->view('admin/report/school_pdf', $data, TRUE);
$this->pdf->create($html, $filename);
I have created a resume builder application.User enters all required details and i am storing all details in database. Then i am fetching those records and displaying it in different templates. I have created 3 templates. Now I want to give download as pdf and download as docx two download buttons. Once user clicks on any of buttons file will be downloaded in their chosen format. Either pdf or docx.
Is it possible to achieve in codeigniter?
i used Tcpdf
Controller Code is
the code written in controller download $this - > load - > library("Pdf");
// create new PDF document
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
// set auto page breaks
$pdf - > SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
// set image scale factor
$pdf - > setImageScale(PDF_IMAGE_SCALE_RATIO);
// Add a page
// This method has several options, check the source code documentation for more information.
$pdf - > AddPage();
// Set some content to print
$html = $this - > load - > view('resume/res_template1_view', array('left_sidebar' => 'sidebar/left_sidebar', ' right_sidebar' => 'sidebar/right_sidebar'), $data, TRUE);
// Print text using writeHTMLCell()
$pdf - > writeHTML($html, 0, 0, '', '', 0, 1, 0, true, '', true);
//$pdf->writeHTML($html, true, false, true, false, '');
// Close and output PDF document
// This method has several options, check the source code documentation for more information.
$pdf - > Output('resume.pdf', 'D');
Probably you need to use some library in CI to achieve this. Please check below.
you can use Html2Pdf for CI3 library. https://github.com/shyamshingadiya/HTML2PDF-CI3
How to Use
There are 4 options you a required to set in order to create a PDF; folder, filename, paper and HTML
//Load the library
$this->load->library('html2pdf');
//Set folder to save PDF to
$this->html2pdf->folder('./assets/pdfs/');
//Set the filename to save/download as
$this->html2pdf->filename('test.pdf');
//Set the paper defaults
$this->html2pdf->paper('a4', 'portrait');
//Load html view
$this->html2pdf->html(<h1>Some Title</h1><p>Some content in here</p>);
The create function has two options 'save' and 'download'. Save will just write the PDF to the folder you choose in the settings. Download will force the PDF to download in the clients browser.
//Create the PDF
$this->html2pdf->create('save');
Advanced usage
Theres no reason why you can't build and pass a view to the html() function. Also note the create() function will return the saved path if you choose the 'save' option.
$data = array(
'title' => 'PDF Created',
'message' => 'Hello World!'
);
//Load html view
$this->html2pdf->html($this->load->view('pdf', $data, true));
if($path = $this->html2pdf->create('save')) {
//PDF was successfully saved or downloaded
echo 'PDF saved to: ' . $path;
}
Please check above mentioned solution. Let me know if it not works.
I'm using PHPExcel with codeigniter to generate .xlx, .xlxs file, Every thing is working perfect except text formatting. Here is the screenshot of html view that I'm passing to PHPExcel library to generate .xlx file.
And Here is the output.
As you can see that text indentation and styles are removed. Here is my code used to generate output.
public function html_to_excel_download($filename, $data=null){
if ($data != null) {
// proper encoding of data UTF-8 for unicode characters
$data = chr(255).chr(254).iconv("UTF-8", "UTF-16LE//IGNORE", $data);
// Put the data into a temporary file
$tmpfile = time().'.html';
file_put_contents($tmpfile, $data);
// Read the contents of the file into PHPExcel Reader class
$reader = new PHPExcel_Reader_HTML;
$content = $reader->load($tmpfile);
// Excel Writer
$objWriter = PHPExcel_IOFactory::createWriter($content, 'Excel2007');
// Download File
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="'.$filename.'"');
header('Cache-Control: max-age=0');
$objWriter->save('php://output');
unlink($tmpfile);
exit();
}
}
How can I indent title text to center?
you may try another way to do that...
Step 1) Define "$this->excel->setActiveSheetIndex(0);" at the top of function
step 2) Define style array and add it as a variable with excel object like,
$styleArray = array(
'font' => array(
'bold' => true,
'color' => array('rgb' => '2F4F4F')
),
'alignment' => array(
'horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,
)
);
Step 3) $this->excel->getActiveSheet()->getStyle('A3:Z3')->applyFromArray($styleArray);
Note: You have to use getStyle() in your code to apply specific styles on column/row
// single column A, setting e.g. horizontal alignment
$objWorksheet->getStyle('A')->getAlignment()->setHorizontal(...);
// range of columns A to K
$objWorksheet->getStyle('A:K')->getAlignment()->setHorizontal(...);
AND you can see full documentation on this site for formatting SHEET
HERE
There are two ways you can get rid of this issue, one is without json array:
$doc->getActiveSheet()->getStyle('A1:H1')->getAlignment()
->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
where $doc = new PHPExcel(); or a PHPExcel object
The second is using the json array as described here
I'm pretty confident that you'll find all instructions about this library in the official documentation
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).
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 );
}
}
