TCPDF 更改最后一页的页脚 [英] TCPDF Change Footer on last page

问题描述

我正在尝试使用 TCPDF 创建 pdf 并且需要在最后一页上使用不同的页脚

I am trying to create a pdf using TCPDF and need a different footer on the last page

使用以下代码，我可以在第一页而不是最后一页获得不同的页脚

using the following code I can get a different footer on the first page but not the last

我已经看过几篇关于这个的帖子，但无法使它工作

I have looked at several post about this but can not make it work

任何帮助实现这一点将不胜感激

Any help implementing this would be much appreciated

public function Footer() {
    $tpages = $this->getAliasNbPages();
    $pages = $this->getPage();

    $footer = 'NORMAL' . $pages . $tpages;

    if ($pages == 1 ) $footer = 'FIRST' . $pages . $tpages;
    if ($pages == $tpages) $footer = 'LAST' . $pages . $tpages;

    $this->Cell(0, 10, $footer, 0, false, 'C', 0, '', 0, false, 'T', 'M');
}

这给了我

第 1 页 - FIRST13第 2 页 - 正常 23第 3 页(最后一页)NORMAL23

page1 - FIRST13 page 2 - NORMAL23 page 3 (Last Page) NORMAL23

答案:

public function Footer() {
    $tpages = $this->getAliasNbPages();
    $pages = $this->getPage();

    $footer = 'NORMAL' . $pages . $tpages;

    if ($pages == 1 ) $footer = 'FIRST' . $pages . $tpages;
    if ($this->end == true) $footer = 'LAST' . $pages . $tpages;

    $this->Cell(0, 10, $footer, 0, false, 'C', 0, '', 0, false, 'T', 'M');
}

function display() {
    #function that has main text
    $this->AddPage();
    $html = '1st page';
    $this->writeHTMLCell($w=0, $h=0, $x='', $y='', $html, $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=true);
     $this->AddPage();
    $html = '2nd page';
    $this->writeHTMLCell($w=0, $h=0, $x='', $y='', $html, $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=true);

     $this->AddPage();
    $html = 'Last page';
    $this->writeHTMLCell($w=0, $h=0, $x='', $y='', $html, $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=true);   
  $this->end = true;
}    

推荐答案

您自己的回答不能回答您在最后一页有不同页脚的问题.
我找到了 以下来自 tcPDF 作者本人的代码，这正是您想要的.

Your own answer does not answer your question to have a different footer on last page.
I found the following code from the author of tcPDF himself, which does exactly what you want.

class mypdf extends tcpdf {

  protected $last_page_flag = false;

  public function Close() {
    $this->last_page_flag = true;
    parent::Close();
  }

  public function Footer() {
    if ($this->last_page_flag) {
      // ... footer for the last page ...
    } else {
      // ... footer for the normal page ...
    }
  }
}

现在该代码有效，但前提是您的最后一页不同.在我的情况下，我可以有 0-X 的最后一页，所以我仍然需要依靠页面计数器.此代码适用于我:

Now that code works, but only if your last page differ. In my case I could have 0-X last pages, so I still need to rely on a page counter. This code works for me:

class mypdf extends tcpdf {

  public $page_counter = 1;

  public function Make() {
    ...

    // Create your own method for determining how many pages you got, excluding last pages
    $this->page_counter = NUMBER;

    ...
  }

  public function Footer() {
    if ($this->getPage() <= $this->page_counter) {
      // ... footer for the normal page ...
    } else {
      // ... footer for the last page(s) ...
    }
  }
}
