Hello again,

I think I have solved point 1 with erAck's answer written at:
https://piwigo.org/forum/viewtopic.php? … 78#p180778

If anyone can help me with 2 and especially 3, I would really appreciate it.

Thanks!

Thanks Katrine,
but where do I find a tutorial to learn how to modify texts and create pages?

Thanks!

Hi guys,

i've been playing around with Piwigo for ~2 weeks and just setting it up. Unfortunately, some plugins are outdated and with a current server running PHP 8.x and the latest Piwigo version 13.7.0, errors / warnings occur again and again. And since there is hardly any help on the web apart from this thread, here is some information about it.

Personally, I'm not a big fan of disabling PHP warnings, it's just taking them with you and running into more problems sooner rather than later. Since I also use Additional Pages and had the same warnings with other plugins (Undefined array key), here is a short description of how to solve this a little more elegantly than just deactivating the warnings, which is generally not recommended.

In this case i will solve the Undefined array key "template_selected" warning in AddionalPages - you can use the same method for similar warnings, also in other plugins. You should ensure that the variable $template_selected exists before using it in the condition. To do this, without wasting too much time here, you can use the isset() function to check if the variable is defined. This will prevent the PHP warning from being raised if the variable is not defined.

Here is the updated code fragment for AdditionalPages/admin/template/add_page.tpl:

<p>
    <strong>{'Load a page model'|@translate}</strong>
    <br>
    <select name="template" id="template">
        <option value="-1">---------</option>
        {foreach from=$TEMPLATES item=tpl}
            <option value="{$tpl.tpl_id}" {if isset($template_selected) && $template_selected==$tpl.tpl_id}selected="selected"{/if}>{$tpl.name}</option>
        {/foreach}
    </select>
</p>
