override div in extended class

[grNadpa]

I have two nearly identical forms: Billing and Payment. So I would like my payment class form to inherit from the Billing form. I am familiar with overriding functions, but not sure if I can easily override code within a function.

Specifically, in the Billing View, I provide the client with four form submit options:

Code: Select all

 <div id="subdiv">
    <span><input type="submit" value="Post+Invoice" name="both" /></span>
    <span><input type="submit" value="Post Only" name="post" /></span>
    <span><input type="submit" value="Invoice Only" name="invoice" /></span>
    <span><input type="submit" value="Cancel" name="bail" /></span>
 </div> <!-- subdiv -->

But in the Payment, I want to provide only two:

Code: Select all

 <div id="subdiv">
    <span><input type="submit" value=Allocate" name="allocate" /></span>
    <span><input type="submit" value="Cancel" name="bail" /></span>
</div> <!-- subdiv -->

The options that occur to me are (1) create a php if statement that checks whether this is a billing or a payment (which violates encapsulation rules I believe)

Code: Select all

 <div id="subdiv">
 <?php if($this->subtitle == "billing") { ?>
    <span><input type="submit" value="Post+Invoice" name="both" /></span>
    <span><input type="submit" value="Post Only" name="post" /></span>
    <span><input type="submit" value="Invoice Only" name="invoice" /></span>
    <span><input type="submit" value="Cancel" name="bail" /></span>
  <?php } else { ?>
    <span><input type="submit" value=Allocate" name="allocate" /></span>
    <span><input type="submit" value="Cancel" name="bail" /></span>
 <?php } // end ifelse billing ?>
 </div> <!-- subdiv -->

or (2) create a Public Function to be overridden depending on the View invocation.

Code: Select all

 <div id="subdiv">
<?php $this->BuildSubmit() ?>
</div> <!-- subdiv -->

I plan to opt for the latter, but wonder if there is better approach.

Just show an itemised bill using a well designed display, i.e. items, sub total (maybe), post, tax and total; it gets too confusing otherwise.

Thank you. But that was not my question. This is an inheritance/polymorphism challenge:

I would like my payment class form to inherit from the Billing form. I am familiar with overriding functions, but not sure if I can easily override code within a function.
