Here is the way to custom error message when editing :

 

1、modify Grocery_CRUD.php

protected function db_update($state_info)
{

...

if($this->callback_before_update !== null)
{
$callback_return = call_user_func($this->callback_before_update, $post_data, $primary_key);

if(!empty($callback_return) && is_array($callback_return))
{
$post_data = $callback_return;
}
elseif($callback_return === false)
{
return false;
}elseif( is_string($callback_return))
{
return array('status' => false,'message' => $callback_return);
}


}

 

...

 

}

 

 

 

 

protected function update_layout($update_result = false, $state_info = null)

{
@ob_end_clean();
if($update_result === false)
{
echo json_encode(array('success' => $update_result));
}elseif(isset($update_result['status'])){
//TODO:custom error
$error_message = '<p>'.$update_result['message']. '</p>';
echo json_encode(array(
'success' => $update_result['status'] ,
'error_message' => $error_message,
'update_error_message' => $error_message,
'update_error' => $error_message,
));
}

else
{

 

...

 

}

 

2、edit.js

 

...

 

$('#crudForm').ajaxSubmit({

dataType: 'text',
cache: 'false',
beforeSend: function(){
$("#FormLoading").show();
},
success: function(result) {
data = $.parseJSON(result);
if (data.success) {

if(save_and_close)
{
if ($('#save-and-go-back-button').closest('.ui-dialog').length === 0) {
window.location = data.success_list_url+'?type=edit';
//form_success_message(data.success_list_url);
} else {
$(".ui-dialog-content").dialog("close");
success_message(data.success_message);
}

return true;
}

form_success_message(data.success_message);
}else if (!data.success & data.error_message != null){
//TODO:custom error message
form_error_message(data.error_message);
}
else {
form_error_message(message_update_error);
}
},
error: function(){
form_error_message( message_update_error );
}
});

...

 

3、in you callback function, just return the string of your error message:

 

function before_xxx_update_callback($post_array, $primary_key) {

if( error ){
$message = 'error message';
return $message;
}

return $post_array;

}

 

 

To make it extendibility , you may define Cutom_Grocery_CRUD.php extending Grocery_CRUD.php , then modify Cutom_Grocery_CRUD.php.
