Etemplate_widget - post process problems

Randy_J_Houlahan_B.S 2009-06-20 10:08:25 UTC #1

Hello Ralf & Nathan,

I am working on a captcha widget which is nearly finished. I am trying to validate the code in the post process function of my widget class and all post_process function parameters are empty. As a result I cannot do my check to see if the code is correct and send the appropriate validation errors.

post_process($name,&$value,&$extension_data,&$loop,&$tmpl,$value_in)

Any thoughts on why all the parameters would be empty?

Hi Randy,

you gave not much info to help you.

I can only guess: the user is displayed some input field, which you want
to validate in the post_process function. The function of post_process
is to take the result from $value_in, validate it and maybe modify it
and then return it in $value.

So possible code might look like:

function
pre_process($name,&$value,&$cell,&$readonlys,&$extension_data,&$tmpl)
{
// store correct result of captcha for post_process validation
$extension_data = ‘123’;

// further code

}

function
post_process($name,&$value,&$extension_data,&$loop,&$tmpl,$value_in)
{
if ($value_in != $extension_data)
{
etemplate::set_validation_error($name,lang("’%1’ is not valid --> go
away !!!");
return false;
}
$value = $value_in; // or true

return true;

}

Sorry for the lack of detail. $value, $value_in, &$extension_data,&$loop,&$tmpl are all empty when the post_process is called/executed in my widget. I cannot add my validation error as a result.

So $value_in and $name has no value to compare and set the validation error. The name of the widget when created in the editor is named captcha.

I just realized I cannot print anything to the screen in post_process. Sorry. It makes it difficult to debug when I cannot see the value of $value, $value_in, &$extension_data,&$loop,&$tmpl.

I am a trial and error programmer :-P.

Thanks.

Then I would say, there’s something seriously wrong with your widget

What about posting the code here …

Yes something is seriously wrong with my widget :-P. I am scraping what I have and starting from scratch. Too embarrassed to post what I have now :-P.

Please note the docs for etemplate are returning a 404 error. http://www.egroupware.org/egwdoc/li_etemplate.html

Thanks Again,

Randy

Hello Ralf,

Nearly there now, it works but no errors are displayed. http://www.roadwarriors.ca/on_line_trial_request
Problem is my validation errors are not appearing. My code comparison values are there and the comparison is functioning properly. However the actual html error is not being displayed.

Everything works except for the displaying of the errors.

I needed to store the code in the captcha class for sound and image generation as well as pre and post proc… It was too hard to access extension_data from outside pre and post process function.

etemplate::set_validation_error seems not to display. I tried a print_r on etemplate::$validation_errors and nothing is generated. DO I have to create a disable label for the errors?

function pre_process($name,&$value,&$cell,&$readonlys,&$extension_data,&$tmpl)
{

	//sets main etemplate cell with data created in etemplate.captcha_widget
	$cell['type'] = 'template';
	$cell['name'] = 'etemplate.captcha_widget';
	$widget =& new etemplate('etemplate.captcha_widget');
	$widget->no_onclick = True;
	$cell['obj'] = &$widget;
	
	// sets refresh icon link properties
	$refresh_image_wig =& $widget->get_widget_by_name('etemplate/refresh.gif');
	$refresh_image_wig['size'] = 'etemplate.captcha_widget.show_image';
	$refresh_image_wig['onclick']='
	document.getElementById(\'show_image\').src = \''.$GLOBALS['egw_info']['server']['webserver_url'].'/index.php?menuaction=etemplate.captcha_widget.show_image&sid=\' + Math.random(); return false;';
	
	//set needed onload for refresh JS
	$GLOBALS['egw']->js->set_onload('"document.getElementById(\'show_image\').src = \''.$GLOBALS['egw_info']['server']['webserver_url'].'/index.php?menuaction=etemplate.captcha_widget.show_image&sid=\' + Math.random(); return false"'
	);
	
	// sets audio icon link properties
	$audio_image_wig =& $widget->get_widget_by_name('etemplate/audio_icon.gif');
	$audio_image_wig['size'] = 'etemplate.captcha_widget.play_sound';
	
	// sects code text field to be needed
	$code_text_wig =& $widget->get_widget_by_name('captcha');
	$code_text_wig['needed'] = 1;
	 

	return True;	// no extra label
}

function post_process($name,&$value,&$extension_data,&$loop,&$tmpl,$value_in)
{
		

		if ($value_in=='' || !isset($value_in))
		{
			etemplate::set_validation_error($name,lang("'%1' Field must not be empty !!!"));
            $loop=TRUE;
			return false; 
		}
		
		if ($this->img->getCode() != $value_in)
		{

			etemplate::set_validation_error($name,lang("'%1' your code is incorrect !!!"));
            $loop=TRUE;
			return false; 
		}
			
}//post process
