如何为每页设置背景色tcpdf [英] How to set the background color for every page tcpdf

问题描述

我目前正在使用TCPDF在我的Web应用程序中生成简历.但是，由于对CSS的支持有限，这使我感到困惑. 现在，我尝试为生成的每个页面应用背景色.但是我只得到第一页的颜色.

I'm currently using TCPDF to generate a resume in my web application. But with the limited support for css have cornered me. Now I'm trying to apply the background color for the every page that is generated. But I'm only getting the color for the first page.

我的代码是:

<?php
class PROFILE_PDF extends TCPDF
{
    public function Header()
    {
        $this->SetFillColor(52, 21, 0, 76);
        $this->Rect(0, 0, $this->getPageWidth(), $this->getPageHeight(), 'DF', "");
    }


    private $footer_data = array();


    public function Footer()
    {
        // Position at 15 mm from bottom
        $this->SetY(-15);
        // Set font
        $this->SetFont('helvetica', 'I', 8);
        // Page number


        $name = <<< EOD
        <p>Curriculum Vitae - {$this->footer_data["name"]}</p>
        <style>
            p {
                color: #F5F5F5;
            }
        </style>

        EOD;
        $this->writeHTMLCell(0, 10, '', '', $name, 0, 1, 0, true, 'L', true);

        $page = <<< EOD

        <p>Page  {$this->getAliasNumPage()} /   {$this->getAliasNbPages()}</p>
        <style>
            p {
                color: #F5F5F5;
            }
        </style>

        EOD;

        $this->writeHTMLCell(0, 10, '', 284, $page, 0, 1, 0, true, 'R', true);

        $style = array('width' => 0.5, 'cap' => 'butt', 'join' => 'miter', 'dash' => 0, 'color' => array(128, 229, 255));
        $this->Line(0, 275, 250, 275, $style);
    }

    public function setFooterData($footer_data)
    {
        $this->footer_data = $footer_data;
    }

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


$pdf->SetLineStyle(array('width' => 2, 'color' => array(112, 128, 144)));

$pdf->Line(0, 0, $pdf->getPageWidth(), 0);
$pdf->Line($pdf->getPageWidth(), 0, $pdf->getPageWidth(), $pdf->getPageHeight());
$pdf->Line(0, $pdf->getPageHeight(), $pdf->getPageWidth(), $pdf->getPageHeight());
$pdf->Line(0, 0, 0, $pdf->getPageHeight());

// set header data
$footer_data = array();
$footer_data["name"] = $personal_data["first_name"] . " " . $personal_data["last_name"];
$pdf->setFooterData($footer_data);

$pdf->setPrintHeader(false);
//$pdf->Header();
// set document information
$pdf->SetCreator(getSiteName());
$pdf->SetAuthor('Mobile Solutions');
$pdf->SetTitle($personal_data["first_name"] . " " . $personal_data["last_name"]);
$pdf->SetSubject("Student's profile");
$pdf->setPrintHeader(false);

$pdf->AddPage();

$pdf->SetFillColor(52, 21, 0, 76);
$pdf->Rect(0, 0, $pdf->getPageWidth(), $pdf->getPageHeight(), 'DF', "");


$pdf->SetFont('courier', 'B', 24);

//some html elements

$pdf->Output($personal_data["first_name"] . "_" . $personal_data["last_name"] . ".pdf", 'D');
?>

在这里，我无法将SetFillColor()函数应用于下一个生成的页面.是什么原因呢? TCPDF文档说它应该适用于所有页面.

Here I'm being unable to apply the SetFillColor() function to next generated pages. What's the reason for that? TCPDF documentation says it should be apply to all the pages.

推荐答案

如果您的意思是使用header函数应用背景色，则应将填充色直接应用于TCPDF中的$pdf->rect函数

if you mean apply a background color with your header function you should apply the fill color directly on the $pdf->rect function in TCPDF

Rect( $x, $y, $w, $h, $style = '', $border_style = array(), $fill_color = array() )

所以您的情况应该是

$this->Rect(0, 0, $this->getPageWidth(),    $this->getPageHeight(), 'DF', "",  array(220, 220, 200));

您必须在最后一个参数中更改数组以应用颜色

where you have to change the array in the last argument to apply your color

它不起作用，因为据我所知，在TCPDF上，如果在true上指定fill参数，则填充颜色将应用于cell和multicell函数

It don't work because on TCPDF the fill color , as far as i know, will apply on the cell and multicell function if you specified the fill argument on true

链接到rect函数TCPDF

foreach ($whatever as $data) {
    if($nextpage)
    {
         $this->Rect(0, 0, $this->getPageWidth(), $this->getPageHeight(), 
                   'DF', "",  array(220, 220, 200)); // where the array is the color expected
    }
}

，但是更好的选择是在标头中定义它，并在TCPDF上用作示例51 链接到示例

but the better option is to define it in the header and use as the example 51 on TCPDF link to the example

public function Header() {
    // get the current page break margin
    $bMargin = $this->getBreakMargin();
    // get current auto-page-break mode
    $auto_page_break = $this->AutoPageBreak;
    // disable auto-page-break
    $this->SetAutoPageBreak(false, 0);
    // set bacground image
    $img_file = K_PATH_IMAGES.'image_demo.jpg';
    $this->Image($img_file, 0, 0, 210, 297, '', '', '', false, 300, '', false, false, 0);
    // restore auto-page-break status
    $this->SetAutoPageBreak($auto_page_break, $bMargin);
    // set the starting point for the page content
    $this->setPageMark();
}

所以这里是

public function Header() {
    // get the current page break margin
    $bMargin = $this->getBreakMargin();
    // get current auto-page-break mode
    $auto_page_break = $this->AutoPageBreak;
    // disable auto-page-break
    $this->SetAutoPageBreak(false, 0);
    $this->Rect(0, 0, $this->getPageWidth(), $this->getPageHeight(), 
               'DF', "",  array(220, 220, 200)); // where the array is the color expected
    $this->SetAutoPageBreak($auto_page_break, $bMargin);
    // set the starting point for the page content
    $this->setPageMark();
}
