Remove custom fields created via package installation

Hi Madhav Shenoy

Use below code in post_uninstall.php . this will help you

    $fieldsByModule = array(
        'Campaigns' => array(
            'is_scheduled_c',
        ),
    );


    require_once('modules/DynamicFields/DynamicField.php');


    foreach ($fieldsByModule as $moduleName => $fields) {
        foreach($fields as $field){
            $dyField = new DynamicField();
            $dyField->bean = BeanFactory::getBean($moduleName);;
            $dyField->module = $moduleName;
            $dyField->deleteField($field);
        }
    }

post_uninstall script is a solution i agree but Why not you create each custom field file and copy file like this? this will automatically delete it from database and from code directory also.Its easy to manage also whenever you want to change/update field just test at local and replace file in package.

    array (

  'from' => '<basepath>/SugarModules/custom/Extension/modules/Campiagns/Ext/Vardefs/sugarfield_yourFiled.php',

  'to' => 'custom/Extension/modules/Campiagns/Ext/Vardefs/sugarfield_yourFiled.php',

    ),
