While Loop in FPDF only prints 1 result - php

Question

i'm having a problem with FPDF, i want to create a While Loop that returns every result that my SQL query does when i use Phpmyadmin, the problem here is that it only returns one. If i use
$pdf->Cell(190,10,''.$pdf_info2['format'].'',1,1,0);
it does print the result i want, but i need to return them in the table as i show below.
Ps: This is my firts question so i appolagise if i wasn't that clear o my problem.
Thanks in advance
$html='<table border="0">
<tr>
<td width="150" height="40" bgcolor="#e6e6e6">Tipo</td>
<td width="150" height="40" bgcolor="#e6e6e6">Formato</td>
<td width="150" height="40" bgcolor="#e6e6e6"> </td>
<td width="150" height="40" bgcolor="#e6e6e6">Pago</td>
<td width="150" height="40" bgcolor="#e6e6e6">Editar</td>
</tr>';
while($pdf_info2 = $smth->fetch(PDO::FETCH_ASSOC)) {
$html2 = '<tr>
<td width="150" height="40" bgcolor="#e6e6e6">'.$pdf_info['format'].'</td>
<td width="150" height="40" bgcolor="#e6e6e6">.$pdf_info['format'].</td>
<td width="150" height="40" bgcolor="#e6e6e6">.$pdf_info['format'].</td>
<td width="150" height="40" bgcolor="#e6e6e6">.$pdf_info['format'].</td>
<td width="150" height="40" bgcolor="#e6e6e6">.$pdf_info['format'].</td>
</tr>';
}
$pdf->WriteHTML($html);
$pdf->WriteHTML($html2);

Answer 1

Use this code:
First you must need to define before loop: $html2 = ''; and concatenate with $html2 .= in while loop see below code for updated code:
$html2 ='';
$html ='<table border="0">
<tr>
<td width="150" height="40" bgcolor="#e6e6e6">Tipo</td>
<td width="150" height="40" bgcolor="#e6e6e6">Formato</td>
<td width="150" height="40" bgcolor="#e6e6e6"> </td>
<td width="150" height="40" bgcolor="#e6e6e6">Pago</td>
<td width="150" height="40" bgcolor="#e6e6e6">Editar</td>
</tr>';
while($pdf_info2 = $smth->fetch(PDO::FETCH_ASSOC)) {
$html2 .='<tr>
<td width="150" height="40" bgcolor="#e6e6e6">'.$pdf_info2['format'].'</td>
<td width="150" height="40" bgcolor="#e6e6e6">'.$pdf_info2['format'].'</td>
<td width="150" height="40" bgcolor="#e6e6e6">'.$pdf_info2['format'].'</td>
<td width="150" height="40" bgcolor="#e6e6e6">'.$pdf_info2['format'].'</td>
<td width="150" height="40" bgcolor="#e6e6e6">'.$pdf_info2['format'].'</td>
</tr>';
}
$pdf->WriteHTML($html);
$pdf->WriteHTML($html2);

Answer 2

**Option1.**first you need to merger data with previous data so use $html .= $html;
Option2 update $pdf_info
to
$pdf_info2
and no need to use 2 $pdf->WriteHTML();
so total code will be
$html='<table border="0">
<tr>
<td width="150" height="40" bgcolor="#e6e6e6">Tipo</td>
<td width="150" height="40" bgcolor="#e6e6e6">Formato</td>
<td width="150" height="40" bgcolor="#e6e6e6"> </td>
<td width="150" height="40" bgcolor="#e6e6e6">Pago</td>
<td width="150" height="40" bgcolor="#e6e6e6">Editar</td>
</tr>';
while($pdf_info2 = $smth->fetch(PDO::FETCH_ASSOC)) {
$html .= '<tr>
<td width="150" height="40" bgcolor="#e6e6e6">'.$pdf_info2['format'].'</td>
<td width="150" height="40" bgcolor="#e6e6e6">'.$pdf_info2['format'].'</td>
<td width="150" height="40" bgcolor="#e6e6e6">'.$pdf_info2['format'].'</td>
<td width="150" height="40" bgcolor="#e6e6e6">'.$pdf_info2['format'].'</td>
<td width="150" height="40" bgcolor="#e6e6e6">'.$pdf_info2['format'].'</td>
</tr>';
}
$pdf->WriteHTML($html);
