使用FPDF輸出從陣列

2014-09-04 38 views

我一直在尋找一種方式，項目符號子彈，或列表的編號添加到我的PDF輸出文件。使用FPDF輸出從陣列

比方說，我有三行文字來自數據庫：

Line 1 
Line 2 
Line 3

我想是FPDF讀每一行，並把子彈在每個前。因此，輸出將如下所示：

• Line 1 
• Line 2 
• Line 3

我發現的最佳解決方案是下面的代碼。它功能完整（如果你有fpdf上傳到你的服務器）。問題是我無法弄清楚如何從文本行的列表：

<? 
     define('FPDF_FONTPATH', 'font/'); 

include('fpdf/fpdf.php'); 

class PDF extends FPDF 

{

} 
$pdf->SetX(10); 
$pdf->MultiCellBltArray($column_width-$pdf->x, 6, $test1); 
$pdf->Ln(10); 


$pdf->Output(); 
?>

的問題是輸出看起來是這樣的：

• This is bulleted text.\n This is a new line of text 
• This is bulleted text.\n This is a new line of text

當我想要它看起來像：

• This is bulleted text. 
• This is a new line of text

這行代碼，似乎以這樣的方式行事，重複上面的$ sample_text：

for ($i=0; $i<2; $i++) 
{ 
    $test1['text'][$i] = $sample_text; 

}

哪裏是你改變了 '$ I < 2' 至可以說， '$ I < 4'，其結果必然是：

• This is bulleted text.\n This is a new line of text 
• This is bulleted text.\n This is a new line of text 
• This is bulleted text.\n This is a new line of text 
• This is bulleted text.\n This is a new line of text

但是，如果我有一組四個不同的變量，我會想將它們放置在樣本文本文件，然後必須通過它的代碼迭代，留下我一個子彈在每個項目前：

$sample_text = "item 1 \n item 2 \n item 3 \n item 4";

而結果將被：

• item 1 
• item 2 
• item 3 
• item 4

\n單引號與打印\n PDF與否裏面，如果你希望它被打斷，因爲你需要用雙引號一個真正的換行符。

此外請確保它期望文本，而不是html

我有同樣的問題。這個附加的fPDF代碼幫助了我，也可以幫助你：http://fpdf.de/downloads/addons/56/（即使它是德國的網站，說明和代碼是英文的）。

此鏈接的描述： 「該腳本允許通過對MultiCellBltArray（）的單個調用輸出項目符號列表，參數通過數組傳遞。」

您可以使用PHP的chr()功能。

//------------- 
// bullet() - shows a bullet point (in current font) 
//------------- 
// 
// @author munkywrench development 
// @since 30/04/05 
// @url http://munkywrench.co.nz 
// 
// @param Int $cellwidth - Sets width of indent 
//-------------- 
function bullet($cellwidth = '0') { 
    //bullet point is chr(127) 
    $this->Cell($cellwidth, 5, chr(127), 0, 0, 'R'); 
}
