How to add Header and Footer in the created PDF file in php

I am using this site as reference: http://www.ros.co.nz/pdf/

I read the readme.pdf but haven't found any function that i开发者_运维知识库nstructs how to add header and footers in every page in the pdf.

You should be able to do this by opening an object, creating your content, closing the object, and then adding the object to your PDF. See pages 18-19 (PDF pages 21-22) of the current (2021) documentation for the relevant class methods.

A brief example:

<?php
include ('class.ezpdf.php');
$pdf =& new Cezpdf();
$pdf->selectFont('fonts/Helvetica.afm');

$footer = $pdf->openObject();
$pdf->addText(50, 50, 8, "some footer text");
$pdf->line(50,60,562,60);
$pdf->closeObject();
$pdf->addObject($footer, "all");

$pdf->ezText('Hello World!',50);
$pdf->ezStream();
?>

90% of the time use BrianS's solution.

Footers can be a good deal more complicated if you don't always know the height of the content.

For a receipt with a tear-off remittance label, for example, something like this works for me:

$ok = 0;
$offset = (0 - $pdf->y);
while (!$ok) {
    $thisPageNum = $pdf->ezPageCount;
    $pdf->transaction('start');

    $offset = $offset + 1;
    $this->ezSetDy($offset);

    // Add your content here

    if ($this->ezPageCount==$thisPageNum) {
        $this->transaction('commit');
        $ok=1;
    } else {
        $this->transaction('rewind');
    }
}

This will make sure your content appears at the bottom of the last page.

For inserting content, you may want to use openObject and closeObject so only the insertion is redone during the while loop.

Edited after long time:

Finally adding answer about latest version of R&OS PDF with the help of this example.

<?php

include 'path/to/Cezpdf.php';

$pdf = new Cezpdf('a4', 'portrait', 'none', null);

$all = $pdf->openObject();
$pdf->saveState();

// header line and text
$pdf->addText(20, 800, 14, 'This is header text');
$pdf->line(20, 790, 580, 790);

// footer line and text
$pdf->line(20, 40, 578, 40);
$pdf->addText(20, 30, 8, 'Left side header text');
$pdf->addText(580, 30, 8, 'Right side header text', 0, 'right');

$pdf->restoreState();
$pdf->closeObject();

$pdf->addObject($all,'all');

$pdf->ezSetMargins(100, 100, 50, 50);

// content text
$text = str_repeat("This is your content.\n", 100);
$pdf->ezText($text, 0, ['justification' => 'full']);

// output
$pdf->ezStream(['Content-Disposition' => 'mypdf.pdf']);

?>

What about using dompdf:

Try this for header and footer:

You can add images and shapes (line, rectangles, etc.) to every page using PDF 'objects'. A PDF object captures all rendering commands as a sort of template that can then be added to multiple pages:

<script type="text/php">

if ( isset($pdf) ) {

  // Open the object: all drawing commands will
  // go to the object instead of the current page
  $footer = $pdf->open_object();

  $w = $pdf->get_width();
  $h = $pdf->get_height();

  // Draw a line along the bottom
  $y = $h - 2 * $text_height - 24;
  $pdf->line(16, $y, $w - 16, $y, $color, 1);

  // Add an initals box
  $font = Font_Metrics::get_font("helvetica", "bold");
  $text = "Initials:";
  $width = Font_Metrics::get_text_width($text, $font, $size);
  $pdf->text($w - 16 - $width - 38, $y, $text, $font, $size, $color);
  $pdf->rectangle($w - 16 - 36, $y - 2, 36, $text_height + 4, array(0.5,0.5,0.5), 0.5);

  // Add a logo
  $img_w = 2 * 72; // 2 inches, in points
  $img_h = 1 * 72; // 1 inch, in points -- change these as required
  $pdf->image("print_logo.png", "png", ($w - $img_w) / 2.0, $y - $img_h, $img_w, $img_h);

  // Close the object (stop capture)
  $pdf->close_object();

  // Add the object to every page. You can
  // also specify "odd" or "even"
  $pdf->add_object($footer, "all");
}

</script>
