Php_value[max_input_vars] works with PHP-FPM, not max_input_vars as stated

Changed max_input_vars but no effect

I am attempting to use a directory wordpress theme on my DigitalOcean Ubuntu 16.04. I am a novice at best when it comes to virtualmin. I have installed and am running Virtualmin/webmin without issue up to now (I have multiple websites where I installed Wordpress using the script installer built into Virtualmin) However when I install this theme it says that my max_input_vars is set too low. It shows the current setting as “1000” and says it needs to be set at “3000” for the theme to work corre…

The correct line to add would be:
php_value[max_input_vars] = 4000

and not max_input_vars = 4000 as stated in that otherwise informative discussion.

@calport

php_value[max_input_vars] = 4000

and not max_input_vars = 4000 as stated in that otherwise informative discussion.

That post was from 2018 by now it should be disregarded as everything has moved on

You can also just use the GUI:

Is 4000 quite a high value?

[Joe]

Yeah, but that’s none of my business. (I leave it at the default, I just changed it in the screenshot to demonstrate.)

[StarlitAri]

thanks for sharing this information

@Joe

I leave it at the default,

and I guess most do - but as with many screens not knowing what the “default” actually is provides little help.
but then I suppose it deters off-roading

Thanks Joe, I don’t know how I missed that.

Virtualmin rocks!

Man, I don’t know what else we can do here. You can also click it to get to the PHP help about this option.

now you have me checking everywhere there is a “Default” to look for a ? tooltip

[Joe]

I’ve asked Ilia to make it more obvious where tooltips are available (since not every option has a tooltip, though we’ve been trying to improve coverage). But yes, many things in Virtualmin have tooltips and sometimes the tooltip shows the default value, sometimes it’s a longer explanation of what the option does.

[shoulders]

Is there any easy place to add tooltips, I seem to remember there was. I have slept since.

[Joe]

It’s very easy to add tooltips.

Find the option name (the label in the HTML), and create an HTML file named <option_name>.html in the module help directory.

The HTML should be very simple and the text should be very concise, since it’s going to be a popup tooltip.

See examples here: virtualmin-gpl/help at master · virtualmin/virtualmin-gpl · GitHub

e.g. virtualmin-gpl/help/accesslog.html at master · virtualmin/virtualmin-gpl · GitHub

The help directory also contains the module help file(s) which is what you get when you click the help icon in the header. It’s all part of Webmin’s help system, which is searchable in a couple of ways/places.

If you have follow up questions, please make a new topic, probably in Developers. We, of course, welcome PRs to add or improve any documentation.

Edit: Also note that those PHP options are done differently, since they link to the PHP documentation rather than a local help file. That’s a special case, the vast majority of tooltips are local help files.
