a good place to start is to create a functions.php file in a test theme and add the code for the first example filter.
add_filter('widget_content', 'basic_widget_content_filter');
function basic_widget_content_filter($content='')
{ return $content."<PRE>THIS APPEARS AFTER EVERY WIDGET</PRE>";
}
and play with that. However if you simply want every widget in a siderbar to output in a specific way you can probably do that more economically with the sidebar config in the theme.

allows you to specify a ‘before_widget’ and ‘after_widget’ if you don’t like the default HTML used
Hi thanks for your reply.
after i posted i carried on and used the example code provided in Other Notes section as a starting point. below is what i ended up with and trying out. basically this code kind of worked i.e it did wrap widgets with the <details> tag, however it wrapped ALL widgets in sidebar and even my top nav menu widget too which is in header area. so thats why i tried the $widget_id to target specific widget areas e.g id='extended-categories-3', which is the id of the specific avh extended categories widget area. unfortunately even when i added the
`add_filter(‘widget_content’, ‘details_wrapper’);
function details_wrapper($content=”, $widget_id=’extended-categories-3′){
return “<details><summary>$content</summary></details>”;
}
the value in the function definition sets a default value for the function, which is the bit between the {curly braces} afterwards. So drop that and just have
function details_wrapper($content, $widget_id)
{ … your code here
}
and you’ll have to put in ‘if’ code blocks like this
if ($widget_id=='extended-categories-3') { echo '<details><summary>' }
to target specific widgets.
HTH
Hi thanks again for your reply.
I was very excited to try the code you posted, but im not sure if im interpreting what you suggested correctly. below is what im putting in functions.php but its not working. is this what the code should look like?
add_filter('widget_content', 'details_wrapper');
function details_wrapper($content, $widget_id){
if ($widget_id=='extended-categories-3') {
echo '<details><summary>'
}
firstly, i checked for syntax examples of a php if statement and there is a ; missing at end of echo line of code. i tried without and it causes Parse error: syntax error, unexpected ‘}’, expecting ‘,’ or ‘;’ so i tried with the ; and the site loads without parse error but all widgets dont display (all sidebar widgets have dissapeared) so obviously that filter is doing something now since adding the if (widget_id==… code.
my original code so far is the closest ive come to getting it to almost work.
theres still two problems:
1. the details tag is wrapping all widgets instead of specific targeted id widgets.
2. the details tag arrow icon for expand/collapse is showing but doesnt seem to expand/collapse the widgets.
they all stay expanded and dont collapse when you click on the details tag arrow.
so does that mean i should be wrapping the details tag around some HTML element WITHIN the widgets output rather than wrapping the WHOLE widgets code. i.e details tag only wrap around <details>summary><H3></H3></summary><details> for example?
sorry I made a very basic error in my suggestion. DON’T ECHO what you want displayed, you have to RETURN it.
the function is provided with the variable $content, which is about to be ECHO’d. this function is your chance to change that value and return it.
{ …
return "<mytag>".$content."</mytag>";
}
Sorry about that – this will have led you astray and made things quite frustrating!
You seem to be getting along fine apart from that, so good luck!
