Thinkphp 整合tcpdf
网上查了些关于tcpdf 使用教程,整合到TP的话,会有些小问题,由于基础还不是很扎实,花了点时间终于整合OK了。下面介绍步骤:
环境:
TP版本:TP3.2.2
tcpdf:tcpdf_6_2_3
1. 将tcpdf_6_2_3.zip解压在Web root目录下面,把examples文件夹下面的tcpdf_include.php文件拷贝到tcpdf文件夹下面,再把tcpdf/config/tcpdf_config.php内容替换成tcpdf/examples/config/tcpdf_config_alt.php中的内容
这里要注意的是:tcp_include.php中 $tcpdf_include_dirs数组要多添加一行:“realpath('./').'/tcpdf/tcpdf.php',”
2. 新建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); $pdf->Output('/var/www/example_038.pdf', 'I');//浏览器预览 //$pdf->Output('example_038.pdf', 'F');//存储文件 //$pdf->Output('example_038.pdf', 'D');//下载文件
这样就可以了。下面说下我碰到的几个问题:
1.我把这些代码拷贝到TP控制器的某个方法里面报错:Class 'Home\Controller\TCPDF' not found
解答:$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
改成$pdf = new \TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
对于tp3.2引入了命名空间,这个‘\’很重要
2.TCPDF ERROR: Unable to create output file: example_038.pdf
解答:$pdf->Output('/var/www/example_038.pdf', 'I');路径要为据对路径。
