问题描述

WriteHTML可以放在Multicell中吗?如何?



我从数据库中检索并显示HTML输出,但想把它放在第二列(比方说),所以我把它放在Multicell中,但没有效果。

以下不适用:

  $ pdf-> Multicell( 70,3.5,$ pdf-> WriteHTML($ html)); 

编辑:我找到了WriteHTMLCell,怎么用?



任何人?



谢谢!

解决方案

WriteHTML脚本来完成工作。



这是fpdf.org为WriteHTML提供的脚本的修改形式

 <?php 
require('fpdf.php');
//函数hex2dec
//从
//返回一个关联数组(键:R,G,B)
函数hex2dec( $ couleur =#000000){
$ R = substr($ couleur,1,2);
$ rouge = hexdec($ R);
$ V = substr($ couleur,3,2);
$ vert = hexdec($ V);
$ B = substr($ couleur,5,2);
$ bleu = hexdec($ B);
$ tbl_couleur = array();
$ tbl_couleur ['R'] = $ rouge;
$ tbl_couleur ['V'] = $ vert;
$ tbl_couleur ['B'] = $ bleu;
返回$ tbl_couleur;
}

//转换像素 - >毫米72 dpi
函数px2mm($ px){
return $ px * 25.4 / 72;
}

函数txtentities($ html){
$ trans = get_html_translation_table(HTML_ENTITIES);
$ trans = array_flip($ trans);
返回strtr($ html,$ trans);
}

将以下代码复制到FILE_NAME文件中,并使用 require(FILE_NAME )将此文件包含到您的脚本中。
完成后,按如下方式调用该函数:

$ $ $ $ $ $ $ c $ $ pdf-> WriteHTML($ html,$ parsed );
$ pdf->多小区(70,3.5,$ parsed);


Can WriteHTML placed in Multicell? How?

I retrieved and display the HTML output from database but want to position it in the 2nd column(let's say) so I put it in Multicell but no effect.

below not works:

$pdf->Multicell(70,3.5, $pdf->WriteHTML($html));

EDITED: i found WriteHTMLCell, how to use?

Anyone?

Thanks!

解决方案

I modified the WriteHTML script to get the job done.

This is the modified form of the script given in fpdf.org for the WriteHTML

<?php
require('fpdf.php');
//function hex2dec
//returns an associative array (keys: R,G,B) from
//a hex html code (e.g. #3FE5AA)
function hex2dec($couleur = "#000000"){
    $R = substr($couleur, 1, 2);
    $rouge = hexdec($R);
    $V = substr($couleur, 3, 2);
    $vert = hexdec($V);
    $B = substr($couleur, 5, 2);
    $bleu = hexdec($B);
    $tbl_couleur = array();
    $tbl_couleur['R']=$rouge;
    $tbl_couleur['V']=$vert;
    $tbl_couleur['B']=$bleu;
    return $tbl_couleur;
}

//conversion pixel -> millimeter at 72 dpi
function px2mm($px){
    return $px*25.4/72;
}

function txtentities($html){
    $trans = get_html_translation_table(HTML_ENTITIES);
    $trans = array_flip($trans);
    return strtr($html, $trans);

Copy the following code into a file say FILE_NAME and use require("FILE_NAME") to include this file in to your script. Once that is done ,call the function as follows

$pdf->WriteHTML($html,$parsed );
$pdf->Multicell(70,3.5, $parsed );
