Calling FLEXIcontent field functions as controller TASKs

FLEXIcontent frontend controller supports calling functions inside a flexicontent plugins as TASKs ... !!

This way you can extend flexicontent controller without hacking it

NOTE: these functions can of course be called via AJAX too

1. Place your functions inside the joomla plugin (flexicontent field)

e.g. see the code of our "file" field (joomla plugin):

class plgFlexicontent_fieldsFile extends JPlugin
{
    static $field_types = array('file');
    var $task_callable = array('share_file_form', 'share_file_email');

Notice the PHP array:

var $task_callable = array('share_file_form', 'share_file_email');

[b]which states which functions are allowed to be called directly[/b]

2. then of course add the needed functions to the plugin in our example:

function share_file_form() {
 ...
}
function share_file_email() {
 ...
}

3.  then call them with URLs like:

index.php?
option=com_flexicontent
&tmpl=component
&task=call_extfunc
&exttype=plugins
&extfolder=flexicontent_fields
&extname=file
&extfunc=share_file_form
&var1=val1
&var2=val2
&var3=val3
