Why doesn't my FPDF class function SetMargins() effect the first row? - php

Question

I am using the FPDF class to create a pdf based on the results from a mysql query. The information was outputted in a table to pdf as expected but my problem occurred when I used SetMargins() to set the page margins. Everything except the first row is effected. The first line seems to be hardcoded to a certain position or margin definition.
Here is my code:
class Table extends FPDF
{
public function CreateTable($header, $data)
{
//Header
$this->SetFillColor(255);
$this->SetTextColor(0);
$this->SetFont('Arial','B', 12);
foreach ($header as $col) {
$this->Cell($col[1], 10, $col[0], 1, 0, 'C');
//Cell(float w [, float h [, string txt [, mixed border [, int ln [, string align [, boolean fill [, mixed link]]]]]]])
}
$this->Ln();
//Data
$this->SetFillColor(255);
$this->SetTextColor(0);
$this->SetFont('Arial', '', 8);
foreach ($data as $row) {
$i = 0;
foreach ($row as $field) {
$this->Cell($header[$i][1], 6, $field, 1, 0, 'C');
$i++;
}
$this->Ln();
}
}
}
//column headings for the department table
$dept_header = array(array('Name', 75), array('Phone', 40), array('Fax', 40));
//column headings for the team tables
$team_header = array(array('Name', 35), array('Role', 30), array('Office', 25), array('Cell', 25), array('Email', 45), array('Pager', 25));
//get data
$query = new ConnectQuery();
$dept_data = $query->all('SELECT * FROM Table');
$team_data = $query->all('SELECT CONCAT_WS(" ", FIRST_NAME, LAST_NAME), JOB_ROLE, OFFICE_PHONE, MOBILE_PHONE, EMAIL, PAGER_NUM FROM Table2');
$pdf = new Table('P', 'mm', 'Letter');
$pdf->AddPage();
$pdf->SetMargins(5, 5);
$pdf->CreateTable($team_header, $team_data);
$pdf->CreateTable($dept_header, $dept_data);
$pdf->Output();
?>

Answer 1

Just define the page margin BEFORE you add the first page. The position is not reset by setMargins() call, which results in the "hardcoded postition" which was set in AddPage():
$pdf = new Table('P', 'mm', 'Letter');
$pdf->SetMargins(5, 5);
$pdf->AddPage();

Answer 2

There's a property in the FPDF class called $cMargin, which is used to calculate the x-offset of the text before it gets printed within the cell, but there doesn't appear to be a setter for it. It's a public property, so after you've instantiated your FPDF class, just call:
$pdf = new fpdf('P','mm','A4');
$pdf->cMargin = 0;
Or you can workaround your 1st line like
$pdf->Ln(); //workaround for 1st line
$pdf->Cell(..);
