Comment on MODx Snippet: ChunkIf by Duncan Lock

As in, you have a drop-down menu on the form and choosing different entries from the drop-down menu, causes different chunks to be displayed?
Unless you’re going to submit the form, or do something clever with AJAX, no.
This snippet – like all MODx snippets – is evaluated by the MODx Document Parser on the server, as the page is being built, before it’s sent back to the browser. Once the web page has been sent to the browser, it’s out of MODx’s hands, until another request is made to the server – i.e. a page refresh, new page request or a form submission.
If you want to do things on the page after it’s been sent to the browser – without a page refresh – then you need javascript. Javascript – unlike PHP – is a client-side language and runs in the browser, so you can use it to do dynamic things on the page after it’s been sent to the browser. You could certainly show and hide bits of a form, based on selections in a drop-down, using javascript, if that’s what you wanted to do.

Is it possible to use this snippet in eForm tpl with select option to get chunk?

Thanks

You might like to read through this MODx wiki article which covers this in detail:

If this doesn’t answer your question fully, then you might like to try running your site completely un-cached. I sometimes do this for smaller sites with less traffic. The affect on visitors is minimal or non-existent, it smooths out the editing experience for editors and eliminates issues like this. You can change the cache status of all pages on your site via the DocManager module, and set the default in the Configuration tab.

Hi, thanks for this simple but useful snippet.
Related with that I have a question. What about if one of the chunks must contains an snippet call? I did try it an uncached ([!snippetName!]) call but MODx output the snippet call literally, without parsing it. The only way is calling the snippet in cached way ([[snippetName]]), but that isn’t fine for all kind of snippets. Do you have a solution for that?

Regards,
Lester

Thanks for pointing that out Jorgen, it got mangled by the syntax highlighter, I think. I’ve fixed it and changed the highlighter that I’m using.

Cheers,
Dunc

Nevermind. I found that your code in the box above is rendered in HTML entities. So the -> is replaced with the HTML code. Which of course doesn’t get parsed very well.

Hi,

Seems like a very usefull snippet, but can’t seem to get it going. I get an error on line 27, unexpected T_VARIABLE, which means de variable TV doesn’t exist?
Hope you can help me out.

Comment on Choosing syntax highlighting colours for the draw spaces Gedit plugin by Duncan Lock

Yes, if the theme you’re using is in /usr/share/gtksourceview-2.0/styles. You could leave it there and modify it in place, but you’d have to sudo to do it – and it might get overwritten on upgrade if you do.

In other words, go to /usr/share/gtksourceview-2.0/styles, copy the theme file you use to ~/.gnome2/gedit/styles, and then modify it by adding this line.
