create table in pdf with wrap data using fpdf in php

问题

I have a problem in creating table structure in pdf using fpdf library. when any data of perticular cell have a long string then the cell data will overlap with other cell data. So whole table data has been disordered. then data in pdf will not seem correctly.

any one please help me to create table in pdf auto adjust all cells according to data in cell.

    <?php
if($_POST['cmbReportType'] == '1')
{
$fromdate = date_format(date_create($_POST['txtFromDate']), 'd-M-y');
$import = ociparse($c, "SELECT 
                            t2.membercardno, (t1.firstname||' '||t1.middlename||' '||t1.lastname) as fullname,
                            t3.description,
                            to_char(t2.startdate,'DD-MON-YY') startdate,
                            to_char(t2.expirydate,'DD-MON-YY') expirydate,
                            t2.ramount,
                            t1.address1,
                            t1.address2
                        FROM

Try writing problem fields (i.e. description - ones you cannot predict a max length for) using multicell(). This will wrap them on multiple lines.

For each multicell field you will need to use nbLines to see if it is going to wrap and calculate the next line position. you will also need to do a setXY() to set the start of the next cell.

Here is nbLines (found here: http://www.svn.churchtool.org/viewvc/trunk/fpdf/mc_table.php?revision=1&view=markup):

function NbLines($w,$txt) {
//Computes the number of lines a MultiCell of width w will take
$cw=&$this->CurrentFont['cw'];
if($w==0)
    $w=$this->w-$this->rMargin-$this->x;
$wmax=($w-2*$this->cMargin)*1000/$this->FontSize;
$s=str_replace("\r",'',$txt);
$nb=strlen($s);
if($nb>0 and $s[$nb-1]=="\n")
    $nb--;
$sep=-1;
$i=0;
$j=0;
$l=0;
$nl=1;
while($i<$nb)
{
    $c=$s[$i];
    if($c=="\n")
    {
        $i++;
        $sep=-1;
        $j=$i;
        $l=0;
        $nl++;
        continue;
    }
    if($c==' ')
        $sep=$i;
    $l+=$cw[$c];
    if($l>$wmax)
    {
        if($sep==-1)
        {
            if($i==$j)
                $i++;
        }
        else
            $i=$sep+1;
        $sep=-1;
        $j=$i;
        $l=0;
        $nl++;
    }
    else
        $i++;
}
return $nl;
}
