TYPO3 Core

Hi,

on a new server I get the following error message by sending ISO-8859-1 coded FlexForms to Typo3 for saving:

t3lib_error_Exception
PHP Catchable Fatal Error: Argument 2 passed to t3lib_div::array_merge_recursive_overrule() must be an array, string given, called in /home/live/t3lib/class.t3lib_tcemain.php on line 1849 and defined in /home/live/t3lib/class.t3lib_div.php line 1960

Related issue: If I try to get some special chars from the database into a flexform, no data will be displayed.

So I have done a little bit of research and found the solution to just change the charset to utf-8. A difficult thing if the sites exists already with many modules. So I tried to get another solution. And here we are:

I looked into the core and found the line which makes problems:

In the class class.t3lib_div.php there is a function xml2arrayProcess. In there is a line

$parser = xml_parser_create();

For solving this issue I just did the following: Just copied the lines

$match = array();
        preg_match('/^[[:space:]]*<\?xml[^>]*encoding[[:space:]]*=[[:space:]]*"([^"]*)"/',substr($string,0,200),$match);
    $theCharset = $match[1] ? $match[1] : ($TYPO3_CONF_VARS['BE']['forceCharset'] ? $TYPO3_CONF_VARS['BE']['forceCharset'] : 'iso-8859-1');

over the $parser = line above and changed the line to

$parser = xml_parser_create($theCharset);

Thats it. No more errors and I had not to change the charset of the existing site.

Maybe this helps fixing this issue, there are several posts in forums with the same problem.

Kind regards,
Stephan
