CAUSE

jQuery DataTables removes non-visible rows from DOM for performance reasons. When form is submitted, only data for visible checkboxes is sent to the server.

SOLUTION 1. Submit form

You need to turn elements that are checked and don't exist in DOM into upon form submission.

var table = $('#example').DataTable({
   // ... skipped ...
});

$('form').on('submit', function(e){
   var $form = $(this);

   // Iterate over all checkboxes in the table
   table.$('input[type="checkbox"]').each(function(){
      // If checkbox doesn't exist in DOM
      if(!$.contains(document, this)){
         // If checkbox is checked
         if(this.checked){
            // Create a hidden element 
            $form.append(
               $('')
                  .attr('type', 'hidden')
                  .attr('name', this.name)
                  .val(this.value)
            );
         }
      } 
   });          
});

SOLUTION 2: Send data via Ajax

var table = $('#example').DataTable({
   // ... skipped ...
});

$('#btn-submit').on('click', function(e){
   e.preventDefault();

   var data = table.$('input[type="checkbox"]').serializeArray();

   // Include extra data if necessary
   // data.push({'name': 'extra_param', 'value': 'extra_value'});

   $.ajax({
      url: '/path/to/your/script.php',
      data: data
   }).done(function(response){
      console.log('Response', response);
   });
});

NOTES

• Each checkbox should have a value attribute assigned with unique value.
• Avoid using id attribute check for multiple elements, this attribute is supposed to be unique.
• You don't need to explicitly enable paging, info, etc. options for jQuery DataTables, these are enabled by default.
• Consider using htmlspecialchars() function to properly encode HTML entities. For example, .
