Magento Admin – Append Block to Admin Login Form

adminadminhtmlblocksevent-observerlayout

I need to append a input field to the admin log in page. I have created an Observer.php hoping to do so. I simply want to add an input to the login form on the admin side.

app\code\local\Wsu\NewtworkSecurities\Model\Observer.php

class Wsu_NewtworkSecurities_Model_Observer extends Mage_Admin_Model_Observer {
    public function appendfeild() {
        echo $this->getLayout()->createBlock('wsu_newtworksecurities/newtworksecurities.feildblock')->toHtml();
    }
}

app\code\local\Wsu\NewtworkSecurities\etc\config.xml

<?xml version="1.0" encoding="utf-8"?>
    <config>
        <modules>
            <Wsu_NewtworkSecurities>

            </Wsu_NewtworkSecurities>
        </modules>
        <global>
            <events>

                        <newtworksecurities>
                            <class>newtworksecurities/observer</class>
                            <method>appendfeild</method>
                        </newtworksecurities>

            </events>
        </global>
    </config>

app\design\adminhtml\default\default\layout\wsu\newtworksecurities.xml

<?xml version="1.0"?>
<layout version="0.1.0">

                <block type="wsu_newtworksecurities/wsu_newtworksecurities" name="wsu_newtworksecurities">
                    <action method="setFormId"><formId>backend_login</formId></action>

                <block type="wsu_newtworksecurities/feildblock" name="newtworksecurities.feildblock"
                   template="wsu/newtworksecurities/feildblock.phtml" />
            </reference>
        </adminhtml_index_login>
    </default>
</layout>

app\design\adminhtml\default\default\template\wsu\newtworksecurities\feildblock.phtml

<input id="url" type="text" name="<?php echo $this->getfeildblock() ?>" />

EDIT

So the answer is that it should be the full package_extension class name in the config events node value. this was the fix, adding the wsu_ to the class value. Although @Vicky hit on another try I did, it was not full solution to appending to the login page. This is what I ended up as

        <controller_action_predispatch_adminhtml_index_login>
            <observers>
                <newtworksecurities>
                    <class>wsu_newtworksecurities/observer</class>
                    <method>appendfeild</method>
                </newtworksecurities>
            </observers>
        </controller_action_predispatch_adminhtml_index_login>

EDIT 2

Now although it I was able to get to the method I have not been able to get the html from the phtml to show up in the <?php echo $this->getChildHtml('form.additional.info'); ?> . I am expecting that app\design\adminhtml\default\default\template\wsu\newtworksecurities\feildblock.phtml was going to show up but as of yet nothing. I have read that I may be seeing that that block is being over write it's self, I have tried to change the events I'm observing with out change. I'm sure it's hitting my method as I added echo "TEST!!!!"; and I see it right at the top as expected. I don't see that block getting the template.

EDIT 3

It is worth noting that it works for the front end if I just do this, no config event, and use the layout update. So this is what works on the front.

app\design\frontend\base\default\layout\newtworksecurities.xml

<?xml version="1.0"?>
<layout>
    <feildset>
        <reference name="head">
            <action method="addJs">
                <script>wsu/newtworksecurities/newtworksecurities.js</script>
            </action>
        </reference>
    </feildset>

    <customer_account_create>
        <update handle="feildset" />
        <reference name="form.additional.info">
            <block type="wsu_newtworksecurities/feildset" name="newtworksecurities.feildset"
                   template="wsu/newtworksecurities/feildset.phtml" />
        </reference>
    </customer_account_create>

    <review_product_list>
        <update handle="feildset" />
        <reference name="product.review.form.fields.before">
                   
            <block type="wsu_newtworksecurities/feildset" name="newtworksecurities.feildset"
                   template="wsu/newtworksecurities/feildset.phtml" />
        </reference>
    </review_product_list>

    <wsu_newtworksecurities_error_index>
        <reference name="content">
            <block type="core/template" name="newtworksecurities.error" template="wsu/newtworksecurities/error.phtml"/>
        </reference>
    </wsu_newtworksecurities_error_index>

</layout>

app\code\local\Wsu\NewtworkSecurities\etc\config.xml

<?xml version="1.0" encoding="utf-8"?>
    <config>
        <modules>
            <Wsu_NewtworkSecurities>

            </Wsu_NewtworkSecurities>
        </modules>

        <frontend>
            <layout>
                <updates>
                    <wsu_newtworksecurities>
                        <file>newtworksecurities.xml</file>
                    </wsu_newtworksecurities>
                </updates>
            </layout>
        </frontend>
    </config>

SO this works but I can't get it do work on the login page. I have added

  <admin>
    <layout>
      <updates>
        <wsu_newtworksecurities>
          <file>newtworksecurities.xml</file>
        </wsu_newtworksecurities>
      </updates>
    </layout>
  </admin>

to the config file and in

app\design\adminhtml\default\default\layout\wsu\newtworksecurities.xml

<?xml version="1.0"?>
<layout version="0.1.0">
    <feildset>

So the answer is that it should not be an observed event. Here is how I got it to work, in the config.xml I needed to update the adminhtml node.

<?xml version="1.0" encoding="utf-8"?>
<config>
  <modules>
    <Wsu_NewtworkSecurities>
      <version>0.1.0</version>
    </Wsu_NewtworkSecurities>
  </modules>
  <adminhtml>
    <layout>
      <updates>
        <wsu_newtworksecurities>
          <file>newtworksecurities.xml</file>
        </wsu_newtworksecurities>
      </updates>
    </layout>
  </adminhtml>
</config>

and in

app\design\adminhtml\default\default\layout\wsu\newtworksecurities.xml

<?xml version="1.0"?>
<layout version="0.1.0">
    <feildset>
        <reference name="head">
            <action method="addJs">
                <script>wsu/newtworksecurities/newtworksecurities.js</script>
            </action>
        </reference>
    </feildset>

    <adminhtml_index_login>
        <update handle="feildset" />
        <reference name="form.additional.info">
            <block type="wsu_newtworksecurities/feildset" name="newtworksecurities.feildset"
                   template="wsu/newtworksecurities/feildset.phtml" />
        </reference>
    </adminhtml_index_login>

    <wsu_newtworksecurities_error_index>
        <reference name="content">
            <block type="core/template" name="newtworksecurities.error" template="wsu/newtworksecurities/error.phtml"/>
        </reference>
    </wsu_newtworksecurities_error_index>

</layout>

Magento – Magento Core: identical block name in one handle

Erfan is right that the html is outputted twice, once as a child of 'checkout.onepage.login' and once as a child of 'checkout.onepage.billing'

Thus there are two child blocks with the same name. Each can have a different template, and each gets rendered as a child of the parent.

To change the persistent block in either of the parent blocks, you need to target the parent block directly such as:

<checkout_onepage_index>
    <reference name="checkout.onepage.login">
            <block type="persistent/form_remember" name="persistent.remember.me" template="my/custom/template.phtml" />
        </reference>
</checkout_onepage_index>

The above will only change the template in the login block.

If you only target the child block 'persistent.remember.me' then magento seems to only change the occurrence of the first found block. Start Speculation: This is most likely in order or alpha occurrence , with 'checkout.onepage.billing' appearing alphabetically before 'checkout.onepage.login', in whatever array is used to store the block internally. The fact that .billing is rendered after .login just makes it look like it is only changing the second occurrence. :) End Speculation

Magento 1.8 – Admin Personal Module Routes Failed

This should be adminhtml below routers and not configsliders in your config.xml.

<admin>
    <routers>
        <adminhtml>                               
            <args>
                <modules>
                    <Namespace_Configslider after="Mage_Adminhtml">Namespace_Configslider_Adminhtml</Namespace_Configslider>
                </modules>                                
            </args>
        </adminhtml>
   </routers>
</admin>

Also, I'd recommend this guide.

http://alanstorm.com/magento_admin_hello_world_revisited

Updated answer based on new info.

Without re-creating the entire module, this is what I changed to get the admin page to show up and not 404. I substituted the namespace for my testing so you will need to change that. You should be able to take it from here.

Pay close attention to the order of the namespace_extensionname in the config edits, these are important.
