form-validationmagento-enterprisePHP

I need to add some form validation for telephone field on admin side for magento. I am looking for correct file to work on

There's already some validation for required fields on the admin sales_order_create I am trying to find the right file that I can work on for the page sales_order_create. I did some search but still I had no luck on my code base.

To add form validation, you'll have to create the file to work on, and hook it to the Magento layout.

Add JavaScript to Sales Order Create

To follow best practices, you'll have to create your own module if you don't have already. I'll start from bottom up, to evidentiate the core need:

Create a layout file

app/design/adminhtml/default/default/layout/mycustom/adminthml.xml

<?xml version="1.0"?>
<layout>
    <adminhtml_sales_order_create_index>
        <reference name="head">
            <action method="addJs">
                <script>mycustom/mycustom.js</script>
            </action>
        </reference>
    </adminhtml_sales_order_create_index>
</layout>

You can skip the mycustom folder if you'd like and name your js file as you want - but remember to change accordingly also in the next steps.

Now you need to reference the xml layout file you just created.

Create your module

Create app\code\local\Mycustom\Adminhtml\etc\config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Mycustom_Adminhtml>
          <version>0.0.1</version>
        </Mycustom_Adminhtml>
    </modules>
    <adminhtml>
        <layout>
            <updates>
                <mycustom>
                    <!-- this will look for the XML file in the app/design/adminhtml/default/default/layout folder -->
                    <file>mycustom/adminhtml.xml</file>
                </mycustom>
            </updates>
        </layout>
    </adminhtml>
</config>

Again, you can also skip the folder and name the xml file as you want.

Now you need to reference your module. Create \app\etc\modules\Mycustom_Adminhtml.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Mycustom_Adminhtml>
            <active>true</active>
            <codePool>local</codePool>
            <depends>
                <Mage_Adminhtml/>
                <Mage_Sales />
            </depends>
        </Mycustom_Adminhtml>
    </modules>
</config>

Now you can create your Javascript file \js\mycustom\mycustom.js and put your validation code in it. For JS form validations you can check this answers: Custom form Validation - Magento

What to be aware of/check:

  • Look into Configuration > Advanced > Advanced to see if your new module is listed and Enabled
  • Log files in /var/log folder
  • Typing errors
  • Root of mentioned paths is /web/ of your Magento installation folder
