Example of thinkPHP Framework Integrating tcpdf Plug in Operation

This article illustrates how the thinkPHP framework integrates tcpdf plug-in operations. Share it for your reference, as follows:

I checked some tutorials about the use of tcpdf on the Internet. If I integrate it into TP, I will have some small problems. Because the foundation is not very solid, I took some time to finally integrate OK. Here are the steps:

Environment:

TP version: TP 3.2. 2

tcpdf:tcpdf_6_2_3

Steps:

1. Unzip tcpdf_6_2_3.zip under the Web root directory, copy the file tcpdf_include. php under the examples folder to the tcpdf folder, and replace the contents of tcpdf/config/tcpdf_config. php with the contents of tcpdf/examples/config/tcpdf_config_ES40php

Note here that in tcp_include. php $tcpdf_include_dirs To add one more row to the array: " realpath('./').'/tcpdf/tcpdf.php' , "

2. New test. php

<?php
// Include the main TCPDF library (search for installation path).
require_once('./tcpdf/tcpdf_include.php');
// create new PDF document
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
// set document information
$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor('Nicola Asuni');
$pdf->SetTitle('TCPDF Example');
$pdf->SetSubject('TCPDF Tutorial');
$pdf->SetKeywords('TCPDF, PDF, example, test, guide');
// set default header data
$pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, PDF_HEADER_TITLE.' wisvalley', 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);
// set auto page breaks
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
// set image scale factor
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
// set some language-dependent strings (optional)
if (@file_exists(dirname(__FILE__).'/lang/eng.php')) {
 require_once(dirname(__FILE__).'/lang/eng.php');
 $pdf->setLanguageArray($l);
}
// ---------------------------------------------------------
// set font
//$pdf->SetFont('helvetica', '', 20);
$pdf->SetFont('stsongstdlight', '', 20);
// add a page
$pdf->AddPage();
$txt = 'your content';
$pdf->Write(0, $txt, '', 0, 'L', true, 0, false, false, 0);
$pdf->Output('/var/www/example_038.pdf', 'I');// Browser preview 
//$pdf->Output('example_038.pdf', 'F');// Store files 
//$pdf->Output('example_038.pdf', 'D');// Download a file 

That's it.

Here are some problems I encountered:

1. I copied these codes into a method of the TP controller and reported an error: Class 'Home\ Controller\ TCPDF' not found

Answer:

$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);

Change to

$pdf = new \TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);

For tp 3.2, namespaces were introduced, and this' \ 'It's important

2.TCPDF ERROR: Unable to create output file: example_038.pdf

Answer: $pdf->Output('/var/www/example_038.pdf', 'I'); The path should be the right path.
