AcceptPageBreak

boolean AcceptPageBreak()

Description

Whenever a page break condition is met, the method is called, and the break is issued or not depending on the returned value. The default implementation returns a value according to the mode selected by SetAutoPageBreak().
This method is called automatically and should not be called directly by the application.

Example

The method is overriden in an inherited class in order to obtain a 3 column layout:

class PDF extends FPDF
{
var $col = 0;

function SetCol($col)
{
    // Move position to a column
    $this->col = $col;
    $x = 10+$col*65;
    $this->SetLeftMargin($x);
    $this->SetX($x);
}

function AcceptPageBreak()
{
    if($this->col<2 column="" go="" next="" this-="" to="">SetCol($this->col+1);
        $this->SetY(10);
        return false;
    }
    else
    {
        // Go back to first column and issue page break
        $this->SetCol(0);
        return true;
    }
}
}

$pdf = new PDF();
$pdf->AddPage();
$pdf->SetFont('Arial','',12);
for($i=1;$i<=300;$i++)
    $pdf->Cell(0,5,"Line $i",0,1);
$pdf->Output();

AddFont

AddFont(string family [, string style [, string file]])

Description

Imports a TrueType, OpenType or Type1 font and makes it available. It is necessary to generate a font definition file first with the MakeFont utility.
The definition file (and the font file itself when embedding) must be present in the font directory. If it is not found, the error "Could not include font definition file" is raised.

Parameters

family

Font family. The name can be chosen arbitrarily. If it is a standard family name, it will override the corresponding font.

style

Font style. Possible values are (case insensitive):

empty string: regular
B: bold
I: italic
BI or IB: bold italic

The default value is regular.

file

The font definition file.
By default, the name is built from the family and style, in lower case with no space.

Example

$pdf->AddFont('Comic','I');

is equivalent to:

$pdf->AddFont('Comic','I','comici.php');

AddLink

int AddLink()

Description

Creates a new internal link and returns its identifier. An internal link is a clickable area which directs to another place within the document.
The identifier can then be passed to Cell(), Write(), Image() or Link(). The destination is defined with SetLink().

AddPage

AddPage([string orientation [, mixed size]])

Description

Adds a new page to the document. If a page is already present, the Footer() method is called first to output the footer. Then the page is added, the current position set to the top-left corner according to the left and top margins, and Header() is called to display the header.
The font which was set before calling is automatically restored. There is no need to call SetFont() again if you want to continue with the same font. The same is true for colors and line width.
The origin of the coordinate system is at the top-left corner and increasing ordinates go downwards.

Parameters

orientation

Page orientation. Possible values are (case insensitive):

P or Portrait
L or Landscape

The default value is the one passed to the constructor.

size

Page size. It can be either one of the following values (case insensitive):

A3
A4
A5
Letter
Legal

or an array containing the width and the height (expressed in user unit).The default value is the one passed to the constructor

AliasNbPages

AliasNbPages([string alias])

Description

Defines an alias for the total number of pages. It will be substituted as the document is closed.

Parameters

alias: The alias. Default value: {nb}.

Example

class PDF extends FPDF
{
function Footer()
{
    // Go to 1.5 cm from bottom
    $this->SetY(-15);
    // Select Arial italic 8
    $this->SetFont('Arial','I',8);
    // Print current and total page numbers
    $this->Cell(0,10,'Page '.$this->PageNo().'/{nb}',0,0,'C');
}
}

$pdf = new PDF();
$pdf->AliasNbPages();

Cell

Cell(float w [, float h [, string txt [, mixed border [, int ln [, string align [, boolean fill [, mixed link]]]]]]])

Description

Prints a cell (rectangular area) with optional borders, background color and character string. The upper-left corner of the cell corresponds to the current position. The text can be aligned or centered. After the call, the current position moves to the right or to the next line. It is possible to put a link on the text.
If automatic page breaking is enabled and the cell goes beyond the limit, a page break is done before outputting.

Parameters

w

Cell width. If 0, the cell extends up to the right margin.

h

Cell height. Default value: 0.

txt

String to print. Default value: empty string.

border

Indicates if borders must be drawn around the cell. The value can be either a number:

0: no border
1: frame

or a string containing some or all of the following characters (in any order):

L: left
T: top
R: right
B: bottom

Default value: 0.

ln

Indicates where the current position should go after the call. Possible values are:

0: to the right
1: to the beginning of the next line
2: below

Putting 1 is equivalent to putting 0 and calling Ln() just after. Default value: 0.

align

Allows to center or align the text. Possible values are:

L or empty string: left align (default value)
C: center
R: right align

fill

Indicates if the cell background must be painted (true) or transparent (false). Default value: false.

link

URL or identifier returned by AddLink().

Example

// Set font
$pdf->SetFont('Arial','B',16);
// Move to 8 cm to the right
$pdf->Cell(80);
// Centered text in a framed 20*10 mm cell and line break
$pdf->Cell(20,10,'Title',1,1,'C');

Close

Close()

Description

Terminates the PDF document. It is not necessary to call this method explicitly because Output() does it automatically.
If the document contains no page, AddPage() is called to prevent from getting an invalid document.

Error

Error(string msg)

Description

This method is automatically called in case of fatal error; it simply outputs the message and halts the execution. An inherited class may override it to customize the error handling but should always halt the script, or the resulting document would probably be invalid.

Footer

Footer()

Description

This method is used to render the page footer. It is automatically called by AddPage() and Close() and should not be called directly by the application. The implementation in FPDF is empty, so you have to subclass it and override the method if you want a specific processing.

Example

class PDF extends FPDF
{
function Footer()
{
    // Go to 1.5 cm from bottom
    $this->SetY(-15);
    // Select Arial italic 8
    $this->SetFont('Arial','I',8);
    // Print centered page number
    $this->Cell(0,10,'Page '.$this->PageNo(),0,0,'C');
}
}

FPDF

FPDF([string orientation [, string unit [, mixed size]]])

Description

This is the class constructor. It allows to set up the page size, the orientation and the unit of measure used in all methods (except for font sizes).

Parameters

orientation

Default page orientation. Possible values are (case insensitive):

P or Portrait
L or Landscape

Default value is P.

unit

User unit. Possible values are:

pt: point
mm: millimeter
cm: centimeter
in: inch

A point equals 1/72 of inch, that is to say about 0.35 mm (an inch being 2.54 cm). This is a very common unit in typography; font sizes are expressed in that unit.

Default value is mm.

size

The size used for pages. It can be either one of the following values (case insensitive):

A3
A4
A5
Letter
Legal

or an array containing the width and the height (expressed in the unit given by unit).

Default value is A4.

Example

Example with a custom 100x150 mm page size:

$pdf = new FPDF('P','mm',array(100,150));

GetStringWidth

float GetStringWidth(string s)

Description

Returns the length of a string in user unit. A font must be selected.

Parameters

s

GetX

float GetX()

Description

Returns the abscissa of the current position.

GetY

Description

Returns the ordinate of the current position.

Header

Header()

Description

This method is used to render the page header. It is automatically called by AddPage() and should not be called directly by the application. The implementation in FPDF is empty, so you have to subclass it and override the method if you want a specific processing.

Example

class PDF extends FPDF
{
function Header()
{
    // Select Arial bold 15
    $this->SetFont('Arial','B',15);
    // Move to the right
    $this->Cell(80);
    // Framed title
    $this->Cell(30,10,'Title',1,0,'C');
    // Line break
    $this->Ln(20);
}
}

Image

Image(string file [, float x [, float y [, float w [, float h [, string type [, mixed link]]]]]])

Description

Puts an image. The size it will take on the page can be specified in different ways:

explicit width and height (expressed in user unit or dpi)
one explicit dimension, the other being calculated automatically in order to keep the original proportions
no explicit dimension, in which case the image is put at 96 dpi

Supported formats are JPEG, PNG and GIF. The GD extension is required for GIF.

For JPEGs, all flavors are allowed:

gray scales
true colors (24 bits)
CMYK (32 bits)

For PNGs, are allowed:

gray scales on at most 8 bits (256 levels)
indexed colors
true colors (24 bits)

For GIFs: in case of an animated GIF, only the first frame is displayed.

w

Width of the image in the page. There are three cases:

If the value is positive, it represents the width in user unit
If the value is negative, the absolute value represents the horizontal resolution in dpi
If the value is not specified or equal to zero, it is automatically calculated

h

Height of the image in the page. There are three cases:

If the value is positive, it represents the height in user unit
If the value is negative, the absolute value represents the vertical resolution in dpi
If the value is not specified or equal to zero, it is automatically calculated

type

Image format. Possible values are (case insensitive): JPG, JPEG, PNG and GIF. If not specified, the type is inferred from the file extension.
