Magento 1.9 - How to add if-else condition on Sales order email template HTML file?

Question

Following is my sales order email template sample,

Docroot = app\locale\en_US\template\email\sales\order_new.html

 <table cellpadding="0" cellspacing="0" border="0">
                <tr>
                    <td class="email-heading">
                        <h1>Thank you for your order from {{var store.getFrontendName()}}.</h1>     
                        <p>Once your package ships we will send an email with a link to track your order. Your order summary is below. Thank you again for your business.</p>
                    </td>
                    <td class="store-info">
                        <h4>Order Questions?</h4>
                        <p>
                            {{depend store_phone}}
                            <b>Call Us:</b>
                            <a href="tel:{{var phone}}">{{var store_phone}}</a><br>
                            {{/depend}}
                            {{depend store_hours}}
                            <span class="no-link">{{var store_hours}}</span><br>
                            {{/depend}}
                            {{depend store_email}}
                            <b>Email:</b> <a href="mailto:{{var store_email}}">{{var store_email}}</a>
                            {{/depend}}
                        </p>
                    </td>
                </tr>
            </table>

I just want to alter my thank you message based on the website in my multistore website.

If website id == 1 my message should be

<h1>Thank you for your order from {{var store.getFrontendName()}}.</h1>

else

<h1>Welcome our land your order from {{var store.getFrontendName()}}.</h1>

Answer 1

You can not use direct if condition like this

{{if order.websiteid == 1}}
 <p>Your text goes here</p>
{{/if}}

But you can define the function or flag in your order model like this.

with function

public function shouldShowBlock() {
        /* your code to check website condition and return true or false */
    }

and in email template

    {{if order.shouldShowBlock()}}
 <p>Your text goes here</p>
{{/if}}

Just copy app/code/Mage/Sales/Model/Order.php to app/code/local/Mage/Sales/Model/Order.php then write you function to end of that file
