I have this code to show my table:
<form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="POST">
<table cellspacing='0'>
<?php
if(isset($_GET["ordem"])){
if($_GET["ordem"] == 'descendente'){
echo "<thead><tr><th><a title='Ordenar por título' href='visualizarVoucher.php'>Utilizador</a></th>";
echo "<th>Email</th>";
echo "<th>Voucher</th>";
echo "<th>Categoria</th>";
echo "<th>Preço</th>";
echo "<th>Confirmação</th>";
echo "<th>Enviar mail</th>";
echo "</tr></thead>";
}
elseif($_GET["ordem"] == 'ascendente'){
echo "<thead><tr><th><a title='Ordenar por título' href='visualizarVoucher.php?ordem=descendente'>Utilizador</a></th>";
echo "<th>Email</th>";
echo "<th>Voucher</th>";
echo "<th>Categoria</th>";
echo "<th>Preço</th>";
echo "<th>Confirmação </th>";
echo "<th>Enviar mail</th>";
echo ("</tr></thead>");
}
}
else{
echo "<thead><tr><th><a title='Ordenar por título' href='visualizarVoucher.php?ordem=ascendente'>Utilizador</a></th>";
echo "<th>Email</th>";
echo "<th>Voucher</th>";
echo "<th>Categoria</th>";
echo "<th>Preço</th>";
echo "<th>Confirmação</th>";
echo "<th>Enviar mail</th>";
echo("</tr></thead>");
}
while($stmt->fetch()){
echo("<tbody>");
echo("<tr><td>$nomeUser</td>");
echo("<td>$email</td>");
echo("<td>$nomeVoucher</td>");
echo("<td>$categoria</td>");
echo("<td>$preco</td>");
echo("<td>$confirmacao</td>");
$content = file_get_contents($file,$filePDF);
echo("<td><INPUT TYPE='checkbox' NAME='mail[]' multiple='yes'></td>");
echo("</tr>");
echo("</tbody>");
}$stmt->close(); ?>
I have a checkbox in my table and I would like to know how can I get the values of each rows from the table when i selected the checkbox. I want to send email when the user selected multiple checkbox. Thanks
It's possible that the code above is a snippet of a larger page, but if not:
You aren't actually wrapping your input elements in an HTML form tag. Doing so will cause the user agent (presumably a browser) to treat each input tag as something to be submitted to your backend form.
You should wrap the tables in a table element; tbody is a child of a table.
Regardless of the above:
It looks like your PHP code above will render the entire tbody each time the statement fetches a new row, which is a bit weird. I'd assume you only want to render a row containing mail options?
To the best of my knowledge, there is no multiple attribute allowed in a checkbox element. You may be thinking of the select element.
You are not setting a value attribute on your checkbox input tag. If the user actually submits a form, you'll either get a set of empty mail[] variables, or nothing at all, I'm not actually sure which.
Consider the code below: Note that the checkboxes have the same name attribute, but different values.
<form method="post">
<table>
<tbody>
<tr>
<td>
<input type="checkbox" name="mail[]" value="val1" id="mail-val1" />
<label for="mail-val1">Value 1</label>
</td>
</tr>
<tr>
<td>
<input type="checkbox" name="mail[]" value="val2" id="mail-val2" />
<label for="mail-val2">Value 2</label>
</td>
</tr>
<tr>
<td>
<input type="checkbox" name="mail[]" value="val3" id="mail-val3" />
<label for="mail-val3">Value 3</label>
</td>
</tr>
</tbody>
</table>
<input type="submit" />
</form>
Given this form, if the user selects all three of the checkboxes and submits, your server will receive a POST request with the payload:
mail[]=val1&mail[]=val2&mail[]=val3
Depending on how PHP parses that response (it's been about a decade since I've dealt with PHP), you'll probably have an array variable accessible to your application:
# mail == ["val1", "val2", "val3" ]
Hope this helps.
