Generate table from MySQL to PDF (using PHP) - php

Question

I'm trying to export the table (filtered) from MySQL to pdf.
The main problem here is that it only prints the last result on the list, instead of printing all the results.
I have tried other code but I still get the same result. I don't know what is wrong with my code:
<?php
include("configsample.php");
?>
<?php
$string=$_GET['string'];
$course=$_GET['course'];
$category=$_GET['category'];
$from=$_GET['from'];
$to=$_GET['to'];
if ($_REQUEST["string"]<>'') {
$search_string = " AND restu_title LIKE '%".mysql_real_escape_string($_REQUEST["string"])."%'";
}
if ($_REQUEST["course"]<>'') {
$search_course = " AND restu_course='".mysql_real_escape_string($_REQUEST["course"])."'";
}
if ($_REQUEST["category"]<>'') {
$search_category = " AND category='".mysql_real_escape_string($_REQUEST["category"])."'";
}
if ($_REQUEST["from"]<>'' and $_REQUEST["to"]<>'') {
$sql = "SELECT * FROM ".$SETTINGS["data_table"]." WHERE restu_year BETWEEN '".mysql_real_escape_string($_REQUEST["from"])."' AND '".mysql_real_escape_string($_REQUEST["to"])."'".$search_string.$search_course;
} else if ($_REQUEST["from"]<>'') {
$sql = "SELECT * FROM ".$SETTINGS["data_table"]." WHERE restu_year = '".mysql_real_escape_string($_REQUEST["from"])."'".$search_string.$search_course;
} else if ($_REQUEST["to"]<>'') {
$sql = "SELECT * FROM ".$SETTINGS["data_table"]." WHERE restu_year = '".mysql_real_escape_string($_REQUEST["to"])."'".$search_string.$search_course;
} else {
$sql = "SELECT * FROM ".$SETTINGS["data_table"]." WHERE restu_id>0".$search_string.$search_course.$search_category;
}
$html='<table>
<tr style="color:#010101; font:bold 13px Times New Roman; height:40px;">
<th>Research Title</th>
<th>Year</th>
<th>Proponent(s)</th>
<th>Adviser</th>
<th>Research Panel</th>
</tr>';
$sql_result = mysql_query ($sql, $connection ) or die ('request "Could not execute SQL query" '.$sql);
if (mysql_num_rows($sql_result)>0) {
while ($row = mysql_fetch_assoc($sql_result)){
$html2='<tr>
<td style="padding:10px;">'.$row['restu_title'].'</td>
<td style="padding:10px;">'.$row['restu_year'].'</td>
<td style="padding:10px;">'.$row['restu_by'].'</td>
<td style="padding:10px;">'.$row['restu_ad'].'</td>
<td style="padding:10px;">'.$row['restu_panel'].'</td>
</tr>
</table>';
}
}
include("mpdf60/mpdf.php");
$mpdf=new mPDF('c','Letter','','',20,20,18,16,9,9,'L');
$mpdf->SetDisplayMode('fullpage');
$mpdf->AddPage('L');
$mpdf->WriteHTML($html);
$mpdf->WriteHTML($html2);
$mpdf->Output();
exit;
?>

Answer 1

You need to concatenate your text string to avoid $html2 to be overwritten by the next value.
Everytime the loop is running, $html2 is overwritten with the new value. In your case, you need to add a dot just before the equal symbol:
while ($row = mysql_fetch_assoc($sql_result)){
$html .='<tr>
<td style="padding:10px;">'.$row['restu_title'].'</td>
<td style="padding:10px;">'.$row['restu_year'].'</td>
<td style="padding:10px;">'.$row['restu_by'].'</td>
<td style="padding:10px;">'.$row['restu_ad'].'</td>
<td style="padding:10px;">'.$row['restu_panel'].'</td>
</tr>';
}
Be careful to correctly place the </table>. If your SQL request has no result, the table will not be closed, rendering the HTML invalid.
You need to do it like this:
$html='<table>
<tr style="color:#010101; font:bold 13px Times New Roman; height:40px;">
<th>Research Title</th>
<th>Year</th>
<th>Proponent(s)</th>
<th>Adviser</th>
<th>Research Panel</th>
</tr>';
$sql_result = mysql_query ($sql, $connection ) or die ('request "Could not execute SQL query" '.$sql);
if (mysql_num_rows($sql_result)>0) {
while ($row = mysql_fetch_assoc($sql_result)){
$html .='<tr>
<td style="padding:10px;">'.$row['restu_title'].'</td>
<td style="padding:10px;">'.$row['restu_year'].'</td>
<td style="padding:10px;">'.$row['restu_by'].'</td>
<td style="padding:10px;">'.$row['restu_ad'].'</td>
<td style="padding:10px;">'.$row['restu_panel'].'</td>
</tr>';
}
}
$html .= '</table>';

Answer 2

append $html2. You are assigning value in loop so it displaying only last record.
Use like this..
$html2=$html2.'<tr>
<td style="padding:10px;">'.$row['restu_title'].'</td>
<td style="padding:10px;">'.$row['restu_year'].'</td>
<td style="padding:10px;">'.$row['restu_by'].'</td>
<td style="padding:10px;">'.$row['restu_ad'].'</td>
<td style="padding:10px;">'.$row['restu_panel'].'</td>
</tr>';
