php - form variables not passing through POST

Question

I'm able to pass all the form values provided in HTML form, but two of them can't read to post.

I can read following values:

$fname          = $_POST['fname'];
$lname          = $_POST['lname'];
$email          = $_POST['email'];
$cell           = $_POST['cell'];
$address        = $_POST['address'];
$zip            = $_POST['zip'];
$city           = $_POST['city'];
$program        = $_POST['program'];

These two variables always read null values :

$location       = $_POST['program2'];
$batch       = $_POST['batch'];

This is my html code

<div class="form-group">
  <select class="form-control" name="program" id="program" required>
	        <option readonly>Select Your Class</option>
	        <option>7</option>
	        <option>8</option>
	        <option>9</option>
	        <option>10</option>
	        <option>11</option>
	        <option>12</option>
	    </select>
</div>
<div class="form-group">
  <select class="form-control" name="program2" id="program2" required>
	        <option readonly>Select your Choice</option>
	        <option>1</option>
	        <option>2</option>
	        <option>3</option>
	        <option>4</option>
	    </select>
</div>
<div class="form-group">
  <select class="form-control" name="batch" id="batch" required>
	        <option readonly>Select Your Choice</option>
	        <option>1</option>
	        <option>21</option>`enter code here`
	    </select>
</div>

Answer 1

You should add 'value' attribute to the option tag. Something like this:

<option value = "1">1</option>
