passing one variable from one page to another for pdf generation - php

Question

I have a page that I have used to retrieve some excel data written in php... by using phpexcel... this part provides me company information
echo '<form action="final.php" method="post">';
echo "<table border='1'>";
for ($rowcount = $rowCompanyInfoStart; $rowcount <= $rowCompanyInfoEnd; $rowcount++)
{
//$data = $objWorksheet->rangeToArray('A1:' . $maxCell['column'] . $maxCell['row']);
$rangeCoordinates = $colCompanyInfoStart . $rowcount . ':' . $colCompanyInfoEnd . $rowcount;
$rowData = $sheet->rangeToArray($rangeCoordinates, NULL, TRUE, FALSE);
echo "<tr>";
$companyname=$worksheet->getCell($column.$row)->getValue();
// echo $companyname;
foreach($rowData[0] as $result)
{
echo "<td>".$result." </td>";
}
echo "</tr>";
}
echo "</table>";
echo "<br />";
echo '<input type="submit" name="sub" value="Convert into PDF" />';
// echo '<input type="text" name="resName" value="$result">';
function getdatan()
{
global $result; // declare as global
return $result;
}
echo '</form>';
this part is where I get company information... it looks like the table area shown down part...
I retrieve info and able to show as "$result" variable and with submit button named "convert it into pdf" I send it into other php page where I use TCPDF ....
Normally, this part of second page
$pdf->SetFont('times', 'BI', 12);
// add a page
$pdf->AddPage('L', 'A4');
if(isset($_POST['submit']))
{
$result = $_GET['resName'];
$pdf->Write(20, $result, '', 0, 'C', true, 0, false, false, 0);
}
// set some text to print
$txt = <<<EOD
TCPDF Example 003
Custom page header and footer are defined by extending the TCPDF class and overriding the Header() and Footer() methods.
EOD;
// print a block of text using Write()
// $pdf->Write(20, $resultt, '', 0, 'C', true, 0, false, false, 0);
// ---------------------------------------------------------
ob_end_clean();
//Close and output PDF document
$pdf->Output('example.pdf', 'I');
However, I am unable to print "$result" in the second page... can you help me about how to print this table on pdf...
PS: please clarify your help...

Answer 1

Try this
Change :
echo '<input type="submit" name="sub" value="Convert into PDF" />';
To:
echo '<input type="submit" name="resName" value="Convert into PDF" />';
EDIT
Put this at the begining of your second page:
var_dump($_POST);
just to check what you are receiving from the first page.
Also change :
$result = $_GET['resName'];
to this:
$result = $_POST['resName'];

Answer 2

ok since I was on my own... I found solution by myself ....
on the first page of PHP...
session_start();
//rest of your code and then...
if($_SERVER['REQUEST_METHOD'] == 'POST') {
echo '<form action="final.php" method="POST">';
$tablo="<br />";
$tablo = $tablo."<table border=\"1\" cellpadding=\"2\" cellspacing=\"2\" align='center'>";
for ($rowcount = $rowCompanyInfoStart; $rowcount <= $rowCompanyInfoEnd; $rowcount++)
{
//$data = $objWorksheet->rangeToArray('A1:' . $maxCell['column'] . $maxCell['row']);
$rangeCoordinates = $colCompanyInfoStart . $rowcount . ':' . $colCompanyInfoEnd . $rowcount;
$rowData = $sheet->rangeToArray($rangeCoordinates, NULL, TRUE, FALSE);
//fazla bosluk olursa bunları aç ya da hucre bos mu kontrol et (cellExists ile)
//rowData = array_map('array_filter', $rowData);
//$rowData = array_filter($rowData);
$tablo= $tablo."<tr >";
$companyname=$worksheet->getCell($column.$row)->getValue();
// echo $companyname;
foreach($rowData[0] as $result)
{
$tablo= $tablo. "<td>".$result. " </td>";
}
$tablo= $tablo. "</tr>";
}
$tablo= $tablo. "</table>";
echo $tablo;
echo "<br />";
if($_SERVER['REQUEST_METHOD'] != 'POST') {
echo "SESSION Not AVAIL. first run.";
}
else{
$_SESSION['varname'] = $tablo;
}
echo '<input type="submit" name="resName" value="Convert into PDF" />';
}
so here I used both "POST request" instead of just "POST". It sends "REQUEST" without any "POST DATA"... and then for sending the data I created a a variable called "$table" I put all my rows and cell info into that and created a session so that second PHP can retrieve it....
ON the second PHP page I answer "request" and open "session" just like that
session_start();
//rest of your code and then...
if($_SERVER['REQUEST_METHOD'] != 'POST') {
echo "SESSION Not AVAIL. first run.";
$tablo = $_SESSION['varname'];
echo "SESSION now set.";
}
else{
$tablo = $_SESSION['varname'];
//echo "SESSION SET, value: " .$_SESSION['varname']. " and ". $_SESSION['color'];
}
if (isset($_SESSION['varname'])){
$tablo = $_SESSION['varname'];
// print_r($_SESSION);
//echo "Session Set: <br/>" . $tablo;
}
else{
echo "Session not set. Tablo is empty";
// echo "Session Set: <br/>" . $tablo;
}
so that's it!
