<div id="migration.10" class="section"><div class="info"><h1 class="title">Zend Framework 1.0</h1></div>
<p class="para">
When upgrading from a previous release to Zend Framework 1.0 or higher you
should note the following migration notes.
</p>
<div class="section" id="migration.10.zend.controller" name="migration.10.zend.controller"><div class="info"><h1 class="title">Zend_Controller</h1></div>
<p class="para">
The principal changes introduced in 1.0.0RC1 are the introduction of
and default enabling of the
<a href="" class="link">ErrorHandler</a>
plugin and the <a href="" class="link">ViewRenderer</a>
action helper. Please read the documentation to each thoroughly to
see how they work and what effect they may have on your
applications.
</p>
<p class="para">
The <span class="classname">ErrorHandler</span> plugin runs during
<span class="methodname">postDispatch()</span> checking for exceptions, and forwarding
to a specified error handler controller. You should include such a
controller in your application. You may disable it by setting the
front controller parameter <span class="property">noErrorHandler</span>:
</p>
<div class="programlisting php"><div class="phpcode"><div class="php" style="font-family: monospace;"><ol><li style="font-family: 'Courier New', Courier, monospace; color: black; font-weight: normal; font-style: normal;"><div style="font-family: 'Courier New', Courier, monospace; font-weight: normal;"><span style="color: #0000ff;">$front</span>-><span style="color: #006600;">setParam</span><span style="color: #66cc66;">(</span><span style="color: #ff0000;">'noErrorHandler'</span>, <span style="color: #000000; font-weight: bold;">true</span><span style="color: #66cc66;">)</span>;</div></li></ol></div></div></div>
<p class="para">
The <span class="classname">ViewRenderer</span> action helper automates view injection
into action controllers as well as autorendering of view scripts
based on the current action. The primary issue you may encounter is
if you have actions that do not render view scripts and neither
forward or redirect, as the <span class="classname">ViewRenderer</span> will attempt
to render a view script based on the action name.
</p>
<p class="para">
There are several strategies you can take to update your code. In
the short term, you can globally disable the
<span class="classname">ViewRenderer</span> in your front controller bootstrap prior
to dispatching:
</p>
<div class="programlisting php"><div class="phpcode"><div class="php" style="font-family: monospace;"><ol><li style="font-family: 'Courier New', Courier, monospace; color: black; font-weight: normal; font-style: normal;"><div style="font-family: 'Courier New', Courier, monospace; font-weight: normal;"><span style="color: #808080; font-style: italic;">// Assuming $front is an instance of Zend_Controller_Front</span></div></li>
<li style="font-family: 'Courier New', Courier, monospace; color: black; font-weight: normal; font-style: normal;"><div style="font-family: 'Courier New', Courier, monospace; font-weight: normal;"><span style="color: #0000ff;">$front</span>-><span style="color: #006600;">setParam</span><span style="color: #66cc66;">(</span><span style="color: #ff0000;">'noViewRenderer'</span>, <span style="color: #000000; font-weight: bold;">true</span><span style="color: #66cc66;">)</span>;</div></li></ol></div></div></div>
<p class="para">
However, this is not a good long term strategy, as it means most
likely you'll be writing more code.
</p>
<p class="para">
When you're ready to start using the <span class="classname">ViewRenderer</span>
functionality, there are several things to look for in your
controller code. First, look at your action methods (the methods
ending in 'Action'), and determine what each is doing. If none of
the following is happening, you'll need to make changes:
</p>
<ul class="itemizedlist">
<li class="listitem"><p class="para">Calls to <strong class="command">$this->render();</strong></p></li>
<li class="listitem"><p class="para">Calls to <strong class="command">$this->_forward();</strong></p></li>
<li class="listitem"><p class="para">Calls to <strong class="command">$this->_redirect();</strong></p></li>
<li class="listitem">
<p class="para">Calls to the <span class="classname">Redirector</span> action helper</p>
</li>
</ul>
<p class="para">
The easiest change is to disable auto-rendering for that method:
</p>
<div class="programlisting php"><div class="phpcode"><div class="php" style="font-family: monospace;"><ol><li style="font-family: 'Courier New', Courier, monospace; color: black; font-weight: normal; font-style: normal;"><div style="font-family: 'Courier New', Courier, monospace; font-weight: normal;"><span style="color: #0000ff;">$this</span>->_helper-><span style="color: #006600;">viewRenderer</span>-><span style="color: #006600;">setNoRender</span><span style="color: #66cc66;">(</span><span style="color: #66cc66;">)</span>;</div></li></ol></div></div></div>
<p class="para">
If you find that none of your action methods are rendering,
forwarding, or redirecting, you will likely want to put the above
line in your <span class="methodname">preDispatch()</span> or <span class="methodname">init()</span>
methods:
</p>
<div class="programlisting php"><div class="phpcode"><div class="php" style="font-family: monospace;"><ol><li style="font-family: 'Courier New', Courier, monospace; color: black; font-weight: normal; font-style: normal;"><div style="font-family: 'Courier New', Courier, monospace; font-weight: normal;"><span style="color: #000000; font-weight: bold;">public</span> <span style="color: #000000; font-weight: bold;">function</span> preDispatch<span style="color: #66cc66;">(</span><span style="color: #66cc66;">)</span></div></li>

If you are calling <span class="methodname">render()</span>, and you're using <a href="" class="link">the Conventional Modular

make use of autorendering:

<ul class="itemizedlist">

action, you don't need to change a thing.

<p class="para">
If you're calling <span class="methodname">render()</span> with arguments, and

</p>
</li>
</ul>
<p class="para">
If you're not using the conventional modular directory structure,
there are a variety of methods for setting the view base path and

</p>
<p class="para">
If you're using a view object from the registry, or customizing your

including setting a different view script to render, specifying
replacements for all replaceable elements of a view script path

specifications with the <span class="classname">ViewRenderer</span>.
