Helper Data not found in magento

by

The question:

I wrote a new extension and trying to create a configuration setting file in Magento Admin. When I run on browser after clearing the cache I got the error like below

Fatal error: Class 'Mage_GlobalSms_Helper_Data' not found in D:wampwwwprojectappMage.php on line 547

In system.log error log file I found the error below:

2015-05-27T13:40:43+00:00 ERR (3): Warning: include(MageGlobalSmsHelperData.php): failed to open stream: No such file or directory  in D:wampwwwprojectlibVarienAutoload.php on line 93

My appetcmodules file as below:

<?xml version="1.0"?>
<config>
    <modules>
        <Php_GlobalSms>
            <active>true</active>

            <version>0.0.1</version>
        </Php_GlobalSms>
    </modules>
</config>

My config.xml as below:

<config>
<modules>
    <Ucs_GlobalSms>
        <version>0.0.1</version>
    </Ucs_GlobalSms>
</modules>

    </helpers>
    <models>
        <custommodule>
            <class>Ucs_GlobalSms_Model</class>

    <events>
        <customer_register_success>
            <observers>
                <Ucs_GlobalSms_customer_register_success>
                    <type>singleton</type>
                    <class>Ucs_GlobalSms_Model_Observer</class>
                    <method>customerRegisterSuccess</method>
                </Ucs_GlobalSms_customer_register_success>
            </observers>
        </customer_register_success>
    </events>
</global>

My Helper/Data.php as below:

<?php
class Php_GlobalSms_Helper_Data extends Mage_Core_Helper_Abstract {

}

I can find lot of posts on SO saying that Data.php is missing, but everything is there, still I am getting error

The Solutions:

Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.

Method 1

Your helpers declaration should look like this:

<global>
    <helpers>
        <globalsms>
            <class>Php_GlobalSms_Helper</class>
        </globalsms>
    </helpers>
</global>

and you should call your helper in the code like this:

Mage::helper('globalsms');

Method 2

Your module name in module.xml is different in config.xml.

I’m not sure myself what you want to use, Php_GlobalSms or Ucs_GlobalSms?

Method 3

If you enable compilation (System > Tools > Compilation), you need to disable or re-compile it. It is the best that you disable Compilation when you do development.

Method 4

You need to define your helper in the config.xml

<config>
<modules>
    <Php_GlobalSms>
        <version>0.0.1</version>
    </Php_GlobalSms>
</modules>
<admin>
     <routers>
        <adminhtml>
            <args>
                <modules>
                    <ucs_globalsms before="Mage_Adminhtml">Php_GlobalSms_Adminhtml</ucs_globalsms>
                </modules>
            </args>
        </adminhtml>
    </routers>
</admin>
<global>
    <models>
        <custommodule>
            <class>Php_GlobalSms_Model</class>
        </custommodule>
    </models>
    <helpers>
        <globalsms>
            <class>Php_GlobalSms_Helper</class>
        </globalsms>
    </helpers>
    <events>
        <customer_register_success>
            <observers>
                <Php_GlobalSms_customer_register_success>
                    <type>singleton</type>
                    <class>Php_GlobalSms_Model_Observer</class>
                    <method>customerRegisterSuccess</method>
                </Php_GlobalSms_customer_register_success>
            </observers>
        </customer_register_success>
    </events>
</global>

Method 5

You said that you created a configuration setting for the admin area; in the system.xml-file, I assume you have something like this (you should have):

<php_globalsms_options translate="label" module="php_globalsms">[...]

This is where Magento tries to load your helper: it handles the translation, regardless of the fact if you call the helper in any of your files or not. The other answers tell the correct way: update your config.xml file and tell Magento that the GlobalSms-helper resides in your module.

Method 6

I have same problem. I have check my config.xml and check my layout xml :

  <layout>
        <updates>
            <module_name>
                <file>module_name.xml</file>
            </module_name>
        </updates>
    </layout>

I have done mistake in module_name.xml. I have remove that code which is not needed.
