Forum Index / General / SetHelp with unicode characters and overlib

[ This topic is unsolved! ]

Firstly, as this is the first time I post, congratulation for the great work. I have an issue trying to use SetHelpText with unicode characters. My text is in Greek and the text returned in the DIV box by overlib is not encoded properly. I tried the htmlenitites function on the help text, setting also the chartset parameter to utf-8 and kind of works, but some special characters are not translated by htmlentities. Since I do not want to go changing the translation table, I am looking for a more straighforward solution. Has anyone any idea why this occurs in the first place? I searched the overlib site and found nothing appropriate.

The help tekst is first made save by the function "htmlentities" before it is displayed. So, I do not think that's the problem. Is the html-doctype correct? I'm not a star in solving char-encoding problems...

Yes, the doc type is correct. I suspect that somewhere in the FormHandler code there is an encoding issue, but I cannot trace it. Do you associate the language setting with an encoding anywhere?

Nope, not that I am aware of. I do not even know how to do that (never had to use it before). Could you tell mee where I should be looking for?

Teye,

Nevemind that. I think I found the solution with a little change of the setHelpText function. Here it is:

<?php

//        // escape the values from dangerous characters
//        $helpTitle = is_null($helpTitle) ? "%title% - " . $this -> _text( 41 ) : htmlentities( $helpTitle );
//        $helpTitle = preg_replace("/\r?\n/", "\\n", addslashes( $helpTitle ));
//        $helpText  = preg_replace("/\r?\n/", "\\n", addslashes( $helpText ));
//
        $helpTitle = is_null($helpTitle) ? mb_convert_encoding("%title% - ","HTML-ENTITIES","auto") . $this -> _text( 41 ) : mb_convert_encoding($helpTitle,"HTML-ENTITIES","auto" );
        $helpTitle = preg_replace("/\r?\n/", "\\n", addslashes( $helpTitle ));
        $helpText  = preg_replace("/\r?\n/", "\\n", addslashes( $helpText ));
//        // set the help text
//        $this->_help[$field] = array(
//        htmlentities( $helpText ),
//        $helpTitle
//        );
        $this->_help[$field] = array(
        mb_convert_encoding( $helpText,"HTML-ENTITIES","auto" ),
        $helpTitle
        );
?>

I still have a problem with the title taken from the form as I cannot find how to assign the %title% to a variable so that I convert it to a multibyte string. Can you help there?

That happens on line 3338 in class.FormHandler.php:

<?php

/**
* Get the help string
*/
$help = '';
if( array_key_exists( $name, $this->_help) && !$this -> isViewMode() && !$this->isFieldViewMode($name) )
{
    $help = sprintf(
      FH_HELP_MASK,
      $this->_helpIcon,
      $this->_help[$name][0],
      str_replace(
        '%title%',
        addslashes( htmlentities($title) ),
        $this->_help[$name][1]
      )
    );
}

?>

Hi all, possible to include this fix in next release ? utf-8 with setHelp is not good actually.

	Johan Wiegel ^(Admin)	01 March 09 / 11:57
this fix is in the coding as far as i can see. What is not working? can you give an example?

	kreatik	11 June 09 / 18:56
With the latest version : http://img269.imageshack.us/img269/8171/bugutf8.jpg UTF8 are not good supported in FH ! :(

	Johan Wiegel ^(Admin)	16 June 09 / 19:47
can you please send me your sethelp code as a testing example?

	Johan Wiegel ^(Admin)	28 June 09 / 13:06
$oForm->setHelpText('test','éáóçê'); seems to give me the right output. Please send me your sethelptext code to test your situation.
