Magento 1.9 Module – How to Limit Characters in system.xml for Textarea

magento-1.9modulesystem.xml

I want to restrict textarea characters length to 150 characters, My system.xml code is below :

...
<orderPlaceMessage translate="label">
    <label>Message for order place: </label>
    <frontend_type>textarea</frontend_type>
    <sort_order>1</sort_order>
    <show_in_default>1</show_in_default>
    <show_in_website>1</show_in_website>
    <show_in_store>1</show_in_store>

    {how to limit character length }

</orderPlaceMessage>
...

How to to that?

Add the following to the <orderPlaceMessage> element:

<validate>validate-length maximum-length-150</validate>

This will add these validation CSS classes used by prototype.js. If you enter a longer value, you will see this generic validation message:

So it is a good idea to add a comment as well to let the user know what this range is:

<comment>Maximum length: 150 characters</comment>

If the limit is important for data integrity, you should also add server side validatation, using a backend model. Digital Pianism already linked a tutorial for this: http://alanstorm.com/magento_system_config_validation

Error:

When sales_order_save_after event is fire then you can get only one order data that means code at observer is wrong.

Solution:

As i said that when Model is saving then you can get old and new Data using

Current Data: $Object->getOrigData();

and

Changing new Data : $object->getData()

Using those function when you can easy track order status changes.

And suggesting to you that use event sales_order_save_commit_after instead of sales_order_save_after because if any issue has occurred during the save magento is roll back to old data and show the errors.

you can Old status by $OldStatus=$order->getOrigData('status')

and new Status

$NewStatus=$order->getData('status');

Code:

  public  function sendSMS($observer)
    {
        $order = $observer->getEvent()->getOrder();

        if (!$order->getId()) {
            //order not saved in the database
            return $this;
        }

        /* @var $order Mage_Sales_Model_Order */

        $OldData=$order->getOrigData();
        $NewData=$order->getData();
        $OldState==$order->getOrigData('state');
        $NewState=$order->getState();
        $OldStatus=$order->getOrigData('status');
        $NewStatus=$order->getStatus();


        /* Fire sms when New Status  and  old Statu are not same */
        if($OldStatus!=$NewStatus){
            //fire sms;
            $smsMessageTemp =Mage::getModel('core/variable')->loadByCode('template_sms_order_placement_confirmation')->getValue('plain');
        }



        return $this;
    }

yes, Magento 2 still allows you to define the default values inside a configuration file. namespace\modulename\etc\config.xml

<?xml version="1.0"?>
     <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Store:etc/config.xsd">
        <default>

                <groupname>
                    <fieldid>1</fieldid>
                </groupname>
            </sectionname>
        </default>
    </config>

System configuration system.xml
