in codeigniter 3 i have a controller method to create pdf from html content using TCPDF as follow;
public function generatePDF_correct_numbering1() { // Initialize TCPDF $pdf = new TCPDF('L', PDF_UNIT, 'A4', true, 'UTF-8', false); // Set document information $pdf->SetCreator(PDF_CREATOR); $pdf->SetAuthor('Your Name'); $pdf->SetTitle('Generated PDF'); $pdf->SetSubject('PDF with TOC'); $pdf->SetKeywords('TCPDF, PDF, CodeIgniter, TOC'); // set default header data $pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, PDF_HEADER_TITLE, PDF_HEADER_STRING); // set header and footer fonts $pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN)); $pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA)); // set default monospaced font $pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED); // set margins $pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT); $pdf->SetHeaderMargin(PDF_MARGIN_HEADER); $pdf->SetFooterMargin(PDF_MARGIN_FOOTER); // Add a cover page or title page $pdf->AddPage(); $pdf->SetFont('helvetica', 'B', 16); $pdf->Cell(0, 10, 'Generated PDF with Table of Contents', 0, 1, 'C'); // Placeholder for the Table of Contents $pdf->SetFont('helvetica', '', 12); $pdf->AddPage(); $pdf->Cell(0, 10, 'Table of Contents', 0, 1, 'C'); $tocPage = $pdf->getPage(); // Content structure $formattedData = ['Kullanici Profilleri' => ['profil_yonetimi_cover1' => 'Content for contents section.','profil_yonetimi_contents' => 'Content for contents section.', ],'Kullanici Profil Sirketleri' => ['profil_yonetimi_company_governing_body' => 'Content for contents section.','profil_yonetimi_company_natural_capital_accounting' => 'Content for natural capital accounting.', ],'Kullanici Profillerirwrw' => ['profil_yonetimi_cover2' => 'Content for cover 1.','profil_yonetimi_parts' => 'Content for contents section.', ], ]; // Prepare the Table of Contents entries $tocEntries = []; // Generate the content foreach ($formattedData as $section => $subContent) { // Start a new section $pdf->AddPage(); $sectionPage = $pdf->getPage(); // Record starting page for TOC $pdf->SetFont('helvetica', 'B', 14); $pdf->Write(10, $section); $pdf->Ln(10); // Save TOC entry for the section $tocEntries[] = ['title' => $section, 'page' => $sectionPage]; // Add subsection content foreach ($subContent as $subtitle => $content) { // Add subtitle page $pdf->AddPage(); $subtitlePage = $pdf->getPage(); // Record page for the subtitle $pdf->SetFont('helvetica', 'I', 12); $pdf->Write(8, $subtitle); $pdf->Ln(5); $pdf->SetFont('helvetica', '', 10); $pdf->WriteHTMLCell(0, 0, '', '', $content, 0, 1, false, true, 'L', true); $pdf->Ln(5); // Save TOC entry for the subtitle $tocEntries[] = ['title' => $subtitle, 'page' => $subtitlePage]; } } // Go back to TOC page $pdf->setPage($tocPage); $pdf->SetFont('helvetica', '', 12); // Add TOC entries foreach ($tocEntries as $entry) { $pdf->Cell(0, 10, $entry['title'] . ' ........ ' . $entry['page'], 0, 1, 'L'); } // Output the PDF $pdf->Output('generated_pdf_with_toc.pdf', 'I');}i want to add my cstum logo as header instead of default tcpdf logo;
i create my logo as follow:
$logo = $this->db->select('profil_resmi')->from('kullanici_profilleri')->where('id', 89)->get()->row();$full_logo_path = $logo->profil_resmi ? FCPATH . 'assets/image/' . $logo->profil_resmi : FCPATH . 'assets/image/defult_logo-organization.png';$logo_base64 = 'data:image/jpeg;base64,' . base64_encode(file_get_contents($full_logo_path));how should i replace my logo on pdf?
i can not apply the approach in TCPDF Example 003
i need to create pdf in my own controller not a new controller MYPDF as described in this example.
how should i define headers in my controller to apply costum logo to reports.
thanks in advance.
