I'm using TCPDF library to generate PDF of a table .
Table has few number of rows say 10
Among that two rows has same invoice number "78650"
Now i am selecting by invoice number and as desired it should generate PDF with two rows.
But instead it is only fetching the second row that is the last row. That is Serial no 2 is only taken .
Code Below :
<?php
require_once('TCPDF/tcpdf.php');
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
if (@file_exists(dirname(__FILE__).'/lang/eng.php')) {
require_once(dirname(__FILE__).'/lang/eng.php');
$pdf->setLanguageArray($l);
}
$pdf->SetFont('helvetica', '', 9);
$pdf->AddPage();
$html1 = '<table cellspacing="0" class="table table-striped">
<tr>
<th>SL No.</th>
<th>Product</th>
<th>Description</th>
<th>Qty</th>
<th>Total</th>
</tr>';
$sql = ("select * from invoice WHERE invoice_no = 78650 ORDER BY invoice_id ASC");
$result=mysqli_query($connection,$sql);
$i = 1;
while($row = mysqli_fetch_array($result)){
$pr = $row['product'];
$dr = $row['description'];
$qty = $row['qty'];
$total = $row['total'];
$html2 = "<tr>
<td>".$i."</td>
<td>".$pr."</td>
<td>".$dr."</td>
<td>".$qty."</td>
<td>".$total."</td>
</tr>";
$i++; }
$sql_1 = ("select *,SUM(total)as tot from invoice WHERE invoice_no = 78650 GROUP BY invoice_no");
$result_1=mysqli_query($connection,$sql_1);
$row_1 = mysqli_fetch_array($result_1);
$tot = $row_1['tot'];
$html3 = "<tr>
<td></td>
<td></td>
<td></td>
<td>Total: </td>
<td>".$tot."</td>
</tr>
</table>";
$html = $html1.$html2.$html3;
$pdf->writeHTML($html, true, 0, true, 0);
$pdf->lastPage();
$pdf->Output('htmlout.pdf', 'I');
?>
That's because for iteration you're replacing the content of $html2. You will need to append the content instead.
So take the blank $html2 variable outside the loop and append the result as you iterate the loop.
Code would look something like this,
$html2="";
while($row = mysqli_fetch_array($result)){
$pr = $row['product'];
$dr = $row['description'];
$qty = $row['qty'];
$total = $row['total'];
$html2 = $html2."<tr>
<td>".$i."</td>
<td>".$pr."</td>
<td>".$dr."</td>
<td>".$qty."</td>
<td>".$total."</td>
</tr>";
$i++;
}
The second fetch overwrites the variable $html2. You can use an array $html2[$i].
$tbl_header = '<table border="1"><tr>
<th>FirstName</th><th>LastName</th><th>Gender</th><th>E-Mail</th><th>Mobile</th><th>DateOfBirth</th><th>Country</th><th>State</th><th>City</th><th>Address</th><th>Zipcode</th><th>File</th></tr>';
$tbl_footer = '</table>';
$tbl = '';
while($row = mysqli_fetch_array($result))
{
$tbl .= '
<tr><td>'.$row['firstname'].'</td><td>'.$row["lastname"].'</td><td>'.$row["sex"].'</td><td>'.$row["email"].'</td><td>'.$row["mobile"].'</td><td>'.$row["dob"].'</td><td>'.$row["country"].'</td><td>'.$row["state"].'</td><td>'.$row["city"].'</td><td>'.$row["address"].'</td>
<td>'.$row["zipcode"].'</td>
<td><img src="'.$row["file"].'"/></td>
</tr>
';
}
//$pdf->writeHTML($html, true, false, true, false, '');
$pdf->writeHTML($tbl_header . $tbl . $tbl_footer, true, false, false, false, '');
