Get checked checkboxes in PHP - php

Question

I can't get the input of checkboxes in PHP.
Here is my code:
echo "<table>";
while ($zeile = mysqli_fetch_array( $ergebnis, MYSQLI_ASSOC )){
echo "<tr>";
echo "<td> <input type='checkbox' name='check_list[]' id='".$zeile['AGName']."'/> </td>";
echo "<td>". $zeile['AGName'] . "</td>";
echo "</tr>";
}
echo "</table>";
#this is the part that probably isn't correct.
if(!empty($_POST['check_list'])){
$checked_count = count($_POST['check_list']);
echo "You have selected following ".$checked_count." option(s): <br/>";
}
I would like to get the amount of checkboxes checked.
The checkboxes are created in a loop with the input of a database.
Even if this would work, how would I get the id of all of the checked checkboxes?

It seems you are not using the form to submit. Place your table inside the form
<form action="" method="post">
<?php
echo "<table>";
while ($zeile = mysqli_fetch_array( $ergebnis, MYSQLI_ASSOC )){
echo "<tr>";
echo "<td> <input type='checkbox' name='check_list[]' value='".$zeile['AGName']."'/> </td>";
echo "<td>". $zeile['AGName'] . "</td>";
echo "</tr>";
}
echo "</table>";
?>
</form>
You can get the post values
if($_POST){
$checked_count = count($_POST['check_list']);
echo "You have selected following ".$checked_count." option(s): <br/>";
}
Simple form with checkboxes:-
<form name="" action="" method="post">
<input type="checkbox" name="gender[]" value="Male" />Male
<input type="checkbox" name="gender[]" value="Female" />Female
<input type="submit" name="submit" value="Submit" />
</form>
The PHP code to get the selected:-=
if(isset($_POST['gender'])){
$options = $_POST['gender'];
echo implode(',', $options);
}
If you want to pass the id you can do it like
<input type="checkbox" name="gender[2]" value="Male" />Male
<input type="checkbox" name="gender[3]" value="Female" />Female
You can loop through each option
foreach($options as $key => $value){
echo $key.'---'.$value;
}
//$key is the id sepcified, $values is the seected value
