I use an mpdf library to generate pdf querying my database. I have to add columns dynamically in this pdf using checkbox. Each checked box adds a specific column in my pdf and unchecks is to disappear. I would like to know how I do this ..preference using javascript.
<?php
require_once './conexao.php';
$pdo = Conexao::getInstance();
$sql = 'SELECT * FROM eventos';
$stm = $pdo->prepare($sql);
$stm->execute();
$dados = $stm->fetchAll(PDO::FETCH_OBJ);
?>
<html>
<head>
<title>Eventos Sinpro-df</title>
</head>
<body>
<table border="0" cellspacing="0" cellpadding="0" style="width:100%; margin:2px ; border-collapse">
<tr> <th> <a href="http://www.sinprodf.org.br/" target="_Blank" title="Clique aqui e visite nossa página"><img src="./images.jpg" height="200 px" width="423px"/></a> </th></tr>
</table>
Escolha seu evento:<br>
<select name="eventos" id="eventos">
<option value=""> </option>
<?php
foreach ($dados as $value) {
echo "<option value='$value->id'>$value->nome</option>";
}
?>
</select>
<input type="button" value="enviar" onclick="javascript: gerar();" />
<input type="reset" value="Cencelar"/>
</body>
<script type="text/javascript">
function gerar() {
var evento = document.getElementById("eventos").value;
location.href = "./teste.php?id=" + evento;
}
</script>

part of my code. This is a page that selects tables and generates in pdf using mpdf and already has the checkboxes (chekbox) that I want to use to get the columns of the bank and leave in the PDF dynamically ...
