The FPDF Library
- 1. FPDF Creating PDF files with PHP http://www.fpdf.org/ By Mike Creuzer mike.creuzer.com For: The West Suburban Chicago PHP Meetup Group http://suburbanchicagophp.org/
- 2. Why Create PDF files? Because your client wants one Because you need pixel-perfect positioning on printed pages Because you want to have a 'saveable' page Because you want an 'immutable' page Because some things are done easier in PDFs then HTML Because you may want a password protected document Because you want to create the impression of a document Because, Because, Because... Because of the wonderful things it does...
- 3. Why FPDF? FPDF is an existing library, used by many people. Pros: Written by somebody else - no re-inventing the wheel Tested, debugged, and hopefully working code Flexible, extensible, many different modules Many examples of different things you can do with it The price is right! Free! Cons: A bit of a learning curve to get started Infrequently updated (Could just be 'done' at this point)
- 4. What does FPDF say about itself? FPDF is a PHP class which allows to generate PDF files with pure PHP, that is to say without using the PDFlib library. F from FPDF stands for Free: you may use it for any kind of usage and modify it to suit your needs. FPDF has other advantages: high level functions. Here is a list of its main features: Choice of measure unit, page format and margins Page header and footer management Automatic page break Automatic line break and text justification Image support (JPEG, PNG and GIF) Colors Links TrueType, Type1 and encoding support Page compression FPDF requires no extension (except zlib to activate compression and GD for GIF support) and works with PHP4 and PHP5. Source: http://www.fpdf.org/
- 5. A brief example from fpdf.org: <?php require( 'fpdf.php' ); $pdf = new FPDF (); $pdf -> AddPage (); $pdf -> SetFont ( 'Arial' , 'B' , 16 ); $pdf -> Cell ( 40 , 10 , 'Hello World!' ); $pdf -> Output (); ?> Include the class library Create a new class object Add a page to the PDF document Set the font Create a 'cell' and put some text into it Output the PDF file
- 6. A few tips The $ pdf->Output(); call issues headers so the mime type is right so the browser can view the file as a .pdf. Outputting anything directly to the browser before the output call causes a HTML header to be sent at that point, breaking the PDF file. Any output after the call gets interpreted as part of the file, corrupting the PDF file format. Watch those empty lines after the ?> To add functionality, you extend the class. There are many examples of class extensions in the 'scripts' page.
- 7. What I have used FPDF for in the past Auto Generated Printable Course Calendar Created a 'Calendar' format list of classes available to students.Many people work of that format better than a list. Dynamic pre-populated Fax Cover sheet From a contact detail screen, create a pre-filled fax cover sheetExtra space on the cover sheet is upcoming calendar events Automatic Name Badges Create Avery formated name badges Include event logo watermarked on the badgeAutoscale long names to fit width of the badge
- 8. Dynamic Name Badge PDF Creation 8 name badges ready to print! Includes watermarked event logo!
- 9. Name Badge Process I chose to use fpdf to create name badges as a PDF file is formatted for a printed page as opposed to a computer screen. Steps to create a namebadge in a PDF file: Define the size of a badge on the page & spacing between badges Create a .PDF file ready for inserting the names Add the watermarked event image Scale and add the person's name Scale and add the person's company Calculate where the next badge should be placed on the page Output the completed PDF file
- 10. Working code example: Setting Params require( "{$_SERVER['DOCUMENT_ROOT']}/lib/fpdf/fpdf.php" ); $result = getanevent ( $location , $date ); // Get list of names/companies $duplicates = $duplcatesdata = $staffdata = array(); $name = "{$location}_{$date}__(" . date ( "Y-m-d" , time ()) . ").csv" ; // Avery 5895 $topMargin = 5 / 8 ; $leftMargin = 11 / 16 ; $bottomMargin = 1 / 2 ; $height = 7 / 3 ; $width = 27 / 8 ; $gutter = 3 / 8 ; $gap = 11 / 64 ; // Create the PDF class object $pdf =new FPDF ( 'P' , 'in' , 'Letter' ); $pdf -> SetTopMargin ( $topMargin ); $pdf -> SetLeftMargin ( $leftMargin ); $pdf -> SetAutoPageBreak ( TRUE , $bottomMargin - .2 ); $pdf -> AddPage (); $pdf -> SetFont ( 'Arial' , 'B' , 10 );
- 11. Detect and skip duplicates $rowcounter = 1 ; // (actually columns) so we know how many labels we have done foreach( $result as $record ) // loop through the names { // Look for duplicate names if( in_array ( "{$record[1]} {$record[2]}" , $duplicates ) ) { //$duplicatesdata[] = $record; }elseif( strtolower ( substr ( $record [ 7 ], - 20 )) == 'hexagonmetrology.com' ) { // Looking for staff and skipping //$staffdata[] = $record; // We could also print a staff badge here }else{
- 12. Scaling the names/company names // Print the watermark $pdf -> Image ( "{$_SERVER['DOCUMENT_ROOT']}/LOGO.jpg" , $pdf -> GetX () + .5 , $pdf -> GetY () + .55 , $width - 1 ); // Create and capitalize the name from firstname & lastname $content = ucwords ( $record [ 1 ]) . " " . ucwords ( $record [ 2 ]) ; $textsize = 28 ; // default font size $pdf -> SetFont ( 'Arial' , 'B' , $textsize ); while( $pdf -> GetStringWidth ( $content ) > $width - .6 ) { // loop while the name is too big for the badge $textsize --; $pdf -> SetFont ( 'Arial' , 'B' , $textsize ); } // Add the name to the badge $pdf -> Cell ( $width , $height / 2 , $content , '' , '2' , 'C' ); // Capitalize the company name $content = ucwords ( $record [ 3 ]); $textsize = 18 ; // smaller default font size for the company $pdf -> SetFont ( 'Arial' , 'B' , $textsize ); while( $pdf -> GetStringWidth ( $content ) > $width - .6 ) { // loop while the company name is too big for the badge $textsize --; $pdf -> SetFont ( 'Arial' , 'B' , $textsize ); } $pdf -> Cell ( $width , $height / 2 , $content , '' , '' , 'C' );
- 13. Setting up for the next badge // Save this name for duplicate detection $duplicates [] = "{$record[1]} {$record[2]}" ; if( $rowcounter % 2 == 0 ) // Even columns, not rows { $pdf -> Ln ( ( $height / 2 ) + $gap ); // start again at a new line }else // odd (1st) columns { $pdf -> SetXY ( $pdf -> GetX () + $gutter , $pdf -> GetY () - ( $height / 2 ) ); //$pdf->SetY($pdf->GetY() - ((7/3)/2)); } if( $rowcounter % 8 == 0 ) // end of page { $pdf -> AddPage (); } $rowcounter ++; // increment the badge counter } } // Output the pdf file $pdf -> Output (); // could pass in $name if we wanted to save as a file die(); // Hack to make the file download work in Joomla
- 14. FPDF class functions used FPDF - constructor SetTopMargin - set top margin SetLeftMargin - set left margin SetAutoPageBreak - set the automatic page breaking mode AddPage - add a new page SetFont - set font face, style, size Image - output an image GetStringWidth - compute string length Cell - print a cell Ln - line break SetXY - set current x and y positions Output - save or send the document
- 15. Other examples of what FPDF can do: Barcodes Calendars Charts Trees Use existing PDFs as templates Labels Javascript Support in a PDF HTML formatting CMYK & Pantone color support
