[Agavi-Users] Can I nest validators

[Frenzel, Timo - REGIOCAST]

hi,
Can I nest validators?

I want that if a default validator was successful, a customer validator is executed.

 

 

First:

 

<validator class="string" name="invalid-category-name-empty" required="true">

                <arguments base="data">

                <argument>name</argument>

                </arguments>

                <error>No Category</error>

</validator>

 

 

if this was successful

 

 

<validator class="Category_CategoryValidator" name="invalid-category-name">

                <arguments base="data">

                               <argument>name</argument>

                </arguments>

                <errors>

                                <error>Category already exists</error>

                </errors>

                <ae:parameters>

                               <ae:parameter name="export">name</ae:parameter>

                </ae:parameters>

</validator>

Hi,

no, you can't nest normal validators. There a special boolean validators which provide such a functionality (http://www.mivesto.de/agavi/agavi-faq.html#validation_1).

In your case you should use the depends/requires mechanism for this (see http://www.mivesto.de/agavi/agavi-faq.html#validation_4 for a description).

But beware of the scoping issues (which you can already see a glimpse of the in the faq entry), a good reference for the current behaviour and 

it's problems is at http://trac.agavi.org/ticket/1199. in 1.1 this will see some changes (also explained in the ticket) to make the behaviour a lot

more sane.

In your case you don't have to use the base at all, since you can just use array syntax in the argument itself.

So you could write your example as:

<validator class="string" name="invalid-category-name-empty" required="true" provides="category_is_set">

  <argument>data[name]</argument>

  <error>No Category</error>

</validator>

 

 

<validator class="Category_CategoryValidator" name="invalid-category-name" depends="category_is_set">

  <argument>data[name]</argument>

   <error>Category already exists</error>

   <ae:parameter name="export">name</ae:parameter>

</validator>
