Dynamic Output Form

My first very basic plugin I am adding here. I’ll post the code and the plugin itself.
Its a simple idea of extending the output_form to allow variables within them. I like to think of them as functions with arguments.
Only a valid form name is required.
Hope someone else finds it useful.

  1. Name: rlt_output_form v0.3
  2. Type: Public side plugin
  3. Send your form dynamic arguments

Re: Dynamic Output Form

Hey, congrats!

Now that you have your own plugin prefix the thing should install. But, alas, it mutters something about bad_plugin_code (TXP probably speaks a bit nicer here, actually, but I’ve just set it to display the core strings). Please have a look at why it does so.

Re: Dynamic Output Form

uli, thanks for letting me know – the forum was adding some formatting to the code, so it should be installable now.

Re: Dynamic Output Form

Alright, now it installs, but the plugin help is malformed (no visible code example), and in ied_plugin_composer there’s no accessible help text, instead there are some duplicated copyright informations and a function. Can’t advise you there, sorry. (The plugin should be named following the function rlt_output_form, BTW.)

Re: Dynamic Output Form

Not wanting to hijack the thread nor criticize this new plugin, problem I see with this approach (using txp:variables) is that they remain existing after the form is processed. In other words, the variables are set globally.

It would be could if the created (on-the-fly) variables could be scoped just to the form, as it happens with txp:yield.
I’ve suggested named yields in the past, without success. Artagesw was working on scoped variables but I think that won’t see the light of day any time soon.
smd_macro could be an alternative.

Re: Dynamic Output Form

Hi maniqui,

I thought about the global variable issue as well – setting a variable(array(‘name’=>$key, ‘value’=>’‘)) i doubt would unset it.
How do you unset txp variables?

I updated the script to use the correct naming style and added some help and an example.

Re: Dynamic Output Form

There are still issues with your composed plugin package. The code contents that get installed include the actual plugin template. This shouldn’t happen and can causes other issues. For instance error log gets filled by inclusion errors about missing file (zem_tpl.php). How are you compiling the plugins? There is something wrong.

Feature-wise it would be good if it supported yield. You can add yield by passing the functions second argument to the output_form() function as the second parameter.

string output_form( array $atts [ , string $thing=null ] )

You could take a look at the output_form() function to see how $thing is used and what it expects. Which lead to the other thing, missing forms could be let to output_form() to handle instead of retuning a false. The core function will invoke useful error message and all that, which you aren’t and shouldn’t have to. Just call the output_form in any case, it will do the rest.

Variables are stored as a global variable named $variable. The variable contains an array map representing the variables used in the tag.

global $variable;
unset($variable['foobar'], $variable['barfoo']);

Take a look at variable() function to see how it’s used. When it comes to clearing the variables, keep in mind that you can’t merely unset them. The plugin will have to keep track of which variables have been set by it, while keeping already set variables safely intact. You should be able to do this by storing the current variables in a temporary variable, which is then used to check which variables where previously set and which weren’t. Those that weren’t are unset and those that were, are restored to their original state.

Re: Dynamic Output Form

richtestani,

I upgraded you to a plugin author so you can release your plugins in the proper forum

Re: Dynamic Output Form

Just to mention: that’s what cbe_output_form already does.
