I already know how to disable module output in the system config by going to System>Configuration>Advanced and by setting <active>false</active> in etc/modules. What I want to know is how to disable module using the custom tab that I created using system.xml.

Add this code to your system.xml

<fields>
    <enable translate="label">
        <label>Enable</label>
        <frontend_type>select</frontend_type>
        <source_model>adminhtml/system_config_source_yesno</source_model>
        <sort_order>0</sort_order>
        <show_in_default>1</show_in_default>
        <show_in_website>1</show_in_website>
        <show_in_store>1</show_in_store>
        <comment>enable/disable the module</comment>
    </enable>
</fields>

And check this in your code: before your first Action in the module.(this might be in your cron.php or observer.php or indexcontroller) 

$isenabled = Mage::getStoreConfig('section_name/group_name/enable');
if (!$isenabled) {
    return;
}

  • I'd suggest `Mage::getStoreConfigFlag` since it returns `boolean` value. – sv3n Jul 26 '17 at 08:30
  • @sv3n Their only difference is that getStoreConfig() will return the exact value while getStoreConfigFlag(), as its name suggests, returns boolean true or false. Both methods send us to Mage_Core_Model_Store::getConfig() – NID Jul 26 '17 at 08:41

    I know ... in my opinion `Mage::getStoreConfig` should be used for all fields where you want to get the exact value. For all others (yes/no or enabled/disabled) I'd use `Mage::getStoreConfigFlag` since `if (0)` is not completly equal to `if (false)`. Still correct answer :) – sv3n Jul 26 '17 at 08:49
  • @sv3n Yeah i totally agree with you – NID Jul 26 '17 at 08:50

    I found the solution already. It's almost the same as this one, but what I actually did is I created fields in system.xml file and added ACL in adminhtml.xml, I made a method in Helper that checks if its enabled or not using getStoreConfigFlag, and lastly, I placed and if else condition in the block where I want it to get affected. Thank you so much for the ideas. :) – markaugustine Jul 27 '17 at 03:09

You can add that New Enable/Disable field in system.xml , and before your module any code execute check this field value if that is enable then execute otherwise not,this way it can be possible.

you have to use ifconfig in your xml file

for example you make a field in your system.xml

 <enable translate="label">
<label>enable</label>
<frontend_type>select</frontend_type>
<source_model>adminhtml/system_config_source_yesno</source_model>
<sort_order>10</sort_order>
<show_in_default>1</show_in_default>
<show_in_website>1</show_in_website>
<show_in_store>1</show_in_store>

And in your xml file 

<block class="your Blockname" name="name of field" ifconfig="sectionname/groupname/enable">

using if config if your module is enable then it will display otherwise it will not display..!
