strip line breaks from beginning of form outputs

Hello

I’m feeding parameters to a Flash mp3 player and I’m running into problems because the 2nd time (and subsequent times) a form is called it prepends a line break which chokes the Flash movie.

In this example, there are 3 files attached to an article, all of which which I want to feed to the player.

In my article form I’m using two different file forms (files_name and files_description) which loop through the file IDs to output the file-names first, then the corresponding file descriptions (as required by the Flash player).

<param name="FlashVars" value="mp3=<txp:upm_article_file_list form="files_name" />&amp;title=<txp:upm_article_file_list form="files_description" />&amp;height=70&amp;width=282"/>

There are no spaces or breaks in the two file forms – they contain only the relevent <txp:file_download_ /> tags. But in the output, where I need this:

<param name="FlashVars" value="mp3=legs.mp3|arms.mp3|hands.mp3|&amp;title=Legs|Arms|Hands|&amp;height=70&amp;width=282 "/>

I’m getting this instead:

<param name="FlashVars" value="mp3=legs.mp3|
arms.mp3|
hands.mp3|&amp;title=Legs|
Arms|
Hands|&amp;height=70&amp;width=282 "/>

And the player doesn’t like that. I find it strange that if there’s only one file to iterate over then no line break is generated – it only happens after first time each form is called.

The options I can see are:

1. trim the \ns with php trim – which I’ve tried with no success (due to paltry php skills)
2. point the Flash movie to some XML – which it is also built to handle, but which I initially presumed would be the more complicated option
3. find a plugin / hack to strip the breaks

all suggestions gratefully received…

Re: strip line breaks from beginning of form outputs

Has upm_article_file_list got a break attribute? It might be set to <br /> by default.

Re: strip line breaks from beginning of form outputs

It does, it is, and I hadn’t defined it, so you’d expect it to output a <br />

But in fact it doesn’t output any html element between outputs. I tried to set break="" to be sure but that didn’t affect anything.

To be clear, there isn’t any code getting in the way, just pesky line breaks. Does that make sense?
