A custom block with multiple checkboxes

Permalink
I'm new to concrete5 and i wanted to know how to retrieve value of multiple checkboxes having the same name!
As in , if all are checked store and retrieve all three values

<input type="checkbox" name="test[]" value="1"/>
<input type="checkbox" name="test[]" value="2"/>
<input type="checkbox" name="test[]" value="3"/>

It will be an array in the $_POST or $_GET data. If it is a custom block, it will be in the $data parameter of the save method. It will have the same name and because it has [] php will convert it to an array for you.

e.g.
$test = $_POST['test'];


For general debugging, see
http://www.concrete5.org/documentation/how-tos/developers/concrete5...

You can see what parameters c5 sees by doing a dump of $_POST.

That all depends on what your database table looks like. Can you post the relevant declarations of the db.xml.

<?xml version="1.0"?>
<schema version="0.3">
    <table name="simpleTest">
        <field name="bID" type="I">
            <key ></key>
            <unsigned ></unsigned>
        </field>
        <field name="test" type="X2">
        </field>
    </table>
</schema>

Here is the sort of code I tend to use in a save() method.
public function save ($data) {
  if (is_array($data['test'])){  
    $data['test'] = implode(',',array_values($data['test']));
  }else{
    $data['test'] = implode(',',array());
  }
  parent::save($data);
}

If all your test[] checkboxes were checked, it would save the string "1,2,3"

When using in edit/view, you can then do something like:
$unpacked_test = explode(',',$this->test);
foreach (array(1,2,3) as $test_value){
  if (in_array($test_value, $unpacked_test )){
    // stuff to do if $test_value is set
  }
}

(I obviously need to communicate between controller and view somewhere in the middle of that)

Depending on the options, I have also used a similar trick with serialize/unserialize and to/from json.
