Getting dropdown value from system.xml issue in Magento

Question

This is part of my system.xml:

<config>
    <sections>
            <mynamespace_mymodule translate="label" module="mynamespace_mymodule">
        .....
                    <groups>
                       <display translate="label" module="mynamespace_mymodule">
                            <label>Display settings</label>
                            <frontend_type>text</frontend_type>
                            <sort_order>20</sort_order>
                            <show_in_default>1</show_in_default>
                            <show_in_website>1</show_in_website>
                            <show_in_store>1</show_in_store>
                            <fields>
                                <showlinks translate="label">
                                    <label>Custom Text</label>
                                    <frontend_type>select</frontend_type>
                                    <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>
                                    <source_model>adminhtml/system_config_source_yesno</source_model>
                                </showlinks>
                            </fields>
                        </display>
                     </groups>
                 </mynamespace_mymodule>
            </sections>
</config>

This is how I got the value from my dropdown:

Mage::getStoreConfigFlag('mynamespace_mymodule/display/showlinks', 1)

and the results is always false. I checked the value from db and it is 1 or yes. The selected value is yes but it always returns me NOT null but false. Why ?

Your updated code:

  <config>
<sections>
        <mycustommodule translate="label" module="mynamespace_mymodule">
    .....
                <groups>
                   <display translate="label" module="mynamespace_mymodule">
                        <label>Display settings</label>
                        <frontend_type>text</frontend_type>
                        <sort_order>20</sort_order>
                        <show_in_default>1</show_in_default>
                        <show_in_website>1</show_in_website>
                        <show_in_store>1</show_in_store>
                        <fields>
                            <showlinks translate="label">
                                <label>Custom Text</label>
                                <frontend_type>select</frontend_type>
                                <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>
                                <source_model>adminhtml/system_config_source_yesno</source_model>
                            </showlinks>
                        </fields>
                    </display>
                 </groups>
             </mycustommodule>
        </sections>

your code for store configuration.

Mage::getStoreConfigFlag('mycustommodule/display/showlinks', 1)

Answer 2

To get system configuration use this code:

 Mage::getStoreConfig('sections/groups/fields',Mage::app()->getStore()->getId());

so in your case

section is may be wrong.

Mage::getStoreConfig('mynamespace_mymodule/display/showlinks', 1);

If you want to use same function than

 Mage::getStoreConfigFlag('mynamespace_mymodule/display/showlinks', 1)
