Answer 1

Encapsulate your table in a form tag and set the action to your control file. You can access the POST variable as an array.

Answer 2

Try something like the code below. Todo: change YOUR_URL_TO_CATCH_THE_FORM to the URL which needs to catch the form.
<?php include 'menu.php';?>
<?php include 'menu_admin.php';?>
<link rel = "stylesheet" type="text/css" href="Form.css">
<?php include 'connect.php';?>
<?php
$sql = "SELECT * FROM ads";
$result = $db->query($sql);
//the function num_rows() checks if there are more than zero rows returned
if ($result->num_rows > 0) {
echo "<form action=\"YOUR_URL_TO_CATCH_THE_FORM\" method=\"POST\">";
echo "<table><tr><th>SELECT</th><th>ADID</th><th>ADName</th><th>ADCATEGORY</th><th>CONTACTNUMBER</th><th>EXPIRATIONDATE</th></tr>";
// output data of each row
while($row = $result->fetch_assoc()) {
echo "<tr>";
echo "<td>
<input type='checkbox' id = 'checkbox' name='checkbox[]' value=".$row['ADID']." > ".$row['ADID']."
</td>";
echo "<td>" .$row["ADID"]. "</td>";
echo "<td><a href=#>" .$row["ADNAME"]. "</a></td>";
echo "<td>" .$row["ADCATEGORY"]. "</td>";
echo "<td>" .$row["CONTACTNUMBER"]. "</td>";
echo "<td>" .$row["EXPIRATIONDATE"]. "</td>";
echo "</tr>";
}
echo "</table>";
echo "</form>";
} else {
echo "0 results";
}
Then catch the form POST in your "YOUR_URL_TO_CATCH_THE_FORM" php with something like this:
if(isset($_POST) && !empty($_POST))
{
if(isset($_POST['checkbox']) && !empty($_POST['checkbox']))
{
foreach($_POST['checkbox'] as $key => $value)
{
echo 'This is checkbox value '.$key.': '.$value;
}
}
}
