I'm adding a new fieldset with custom params to my template:

    <fields name="params">
        <fieldset name="advanced" addfieldpath="/templates/mytemp/fields">

        <fieldset name="custom">

The name of that fieldset gets used for the Template-Tab as following:


In which language file (that needs to be installed with the template) can i insert that language constant?

de-DE.tpl_mytemp.ini and de-DE.tpl_mytemp.sys.ini is not working.

First I suggest that you do not use language strings containing prefixes of other extensions. You can use your own language strings by adding label attribute to the fieldset:

<fieldset name="custom" label="TPL_MYTEMP_CUSTOM_FIELDSET_LABEL">

The file for template configuration strings is de-DE.tpl_mytemp.ini. Depending on your template setup it should be installed either in language/de-DE or templates/mytemp/language/de-DE. If the file is not loaded, make sure mytemp matches the value of <name> element in templateDetails.xml file. Neither should have tpl_ prefix, apparently. When language files are loaded tpl_ prefix is added automatically so in case you do have it in your template's name, the resulting file would end up being de-DE.tpl_tpl_mytemp.ini.

To further debug language issues enable Debug Language in Global Configuration. With this you'll see which language files are being loaded, which files are missing and if there's any errors.

  • All was done that way. The COM_TEMPLATES_CUSTOM_FIELDSET_LABEL gets displayed in the tab without me doing anything. Seams like this <fieldset name="custom">in the template XML gets parsed, but i don't understand why it's not taking my template name mytemp and thus my language constant.

  • It's not supposed to. If no label is present, it builds this: COM_TEMPLATES_' . $name . '_FIELDSET_LABEL, where $name is fieldset name.

  • Also make sure that your language file has been formatted correctly. If you forget a quote somewhere, or an equals = symbol, then Joomla will only show the language tag (and not the values from the language file).
