PHP TCPDF remove header's bottom border - php

Question

I am trying to create a header in TCPDF, however it always have a border underneath of it. Is there a way I can remove the bottom border?

Answer 1

This works for some versions:
// Call before the addPage() method
$pdf->SetPrintHeader(false);
$pdf->SetPrintFooter(false);

Answer 2

If you don't want to subclass or change the tcpdf source just call the setHeaderData method and specify white line color.
$pdf->setHeaderData('',0,'','',array(0,0,0), array(255,255,255) );

Answer 3

Problem solved by extends the TCPDF class and modify the header and footer.
class MYPDF extends TCPDF {
public function Header()
{
$image_file = K_PATH_IMAGES.'pdf-header.jpg';
$this->Image($image_file, 160, 10, 40, '', 'JPG', '', 'T', false, 20, '', false, false, 0, false, false, false);
$this->SetFont('helvetica', 'B', 10);
}
public function Footer()
{
$this->SetY(-15);
$this->SetFont('helvetica', 'I', 8);
}
}

Answer 4

tcpdf.php:
// print an ending header line
$this->SetLineStyle(array('width' => 0.25 / $this->k, 'cap' => 'butt', 'join' => 'miter', 'dash' => 0, 'color' => array(255, 255, 255)));

Answer 5

If the other solutions posted in this thread does not work, I solved in this way:
TL;DR
In Footer() function in Tcpdf class (tcpdf.php):
Replace this lines:
$this->Cell(0, 0, $pagenumtxt, 'T', 0, 'L'); // line 3527 in version 6.3.1
$this->Cell(0, 0, $this->getAliasRightShift().$pagenumtxt, 'T', 0, 'R'); // line 3530 in version 6.3.1
With this lines
$this->Cell(0, 0, $pagenumtxt, 0, 0, 'L');
$this->Cell(0, 0, $this->getAliasRightShift().$pagenumtxt, 0, 0, 'R');
Alternative way 1
Comment this lines in Footer() function in Tcpdf class (tcpdf.php):
In my file (version 6.3.1) they were placed at line 3524
//Print page number
if ($this->getRTL()) {
$this->SetX($this->original_rMargin);
$this->Cell(0, 0, $pagenumtxt, 'T', 0, 'L');
} else {
$this->SetX($this->original_lMargin);
$this->Cell(0, 0, $this->getAliasRightShift().$pagenumtxt, 'T', 0, 'R');
}
This will disable the render of the page number in the footer but at least it removes the unwanted line.
Alternative way 2
If these methods does not work, search in the tcpdf.php file for this string:
$this->SetLineStyle(array
You should find 3 occurrences, replace the 'color' property of the array with the value [0,0,0] (or the rgb color of your background), this should cause the line to turn white (or the color you set).
I used this method to troubleshoot where the problem was by putting custom weird color and seeing which one was being rendered.
Explanation
The line is rendered because in the lines
$this->Cell(0, 0, $pagenumtxt, 'T', 0, 'L');
$this->Cell(0, 0, $this->getAliasRightShift().$pagenumtxt, 'T', 0, 'R');
The border property is set to 'T' (top border). You can disable the border by set the border property to 0 (see docs here, $border param).
If that doesn't work you can entirely disable the render of the page number (and thus the border), or you can set the border to a custom color that matches you actual background.

Comment this line in Header() function of tcpdf Class :
$this->Cell(($this->w - $this->original_lMargin - $this->original_rMargin), 0, '', 'T', 0, 'C');
