Debugging custom module - content not displaying

Question

I am practicing Magento, So I develop a new custom module . The module is working fine but I have a problem with my layout file. This is what i have got in my layout file.

<?xml version="1.0" encoding="UTF-8"?> 

<layout >


    <ias_myslideshow_index_index>

        <reference name="root">
            <action method="setTemplate">
                <template>page/1column.phtml</template>
            </action>
        </reference>

        <reference name="content">
            <block type="ias/myslideshow_slideshow" name="ias.myslideshow.slideshow" template="IAS/slideshow.phtml" output="toHtml" />
        </reference>

    </ias_myslideshow_index_index>



</layout>

In the block type if I write

block type="core/template"

Then every static content that I have written in the pthml is displayed but if I try to call a function written in my block it throws an error for not finding the method. If I change block type to

block type="ias/myslideshow_slideshow"

             OR

block type="ias/slideshow"

Nothing is display. No static content, no error.

I will really appreciate if some one can let me know what the wrong I am doing. below is my block and config file

public function myMessage(){

    return “I am Iyngaran, This is my module.”;

}

}

    public function myMessage(){

        return “I am Iyngaran, This is my module.”;

    }
}

Answer 1

please try to write below in block type if your module name is myslideshow and the file placed in block folder is slideshow.php because in magento block type "modulename/blockfilename"

"myslideshow/slideshow"

For above magento find block file in below path:

"myslideshow/block/slideshow.php"
