[FIXED] from PHP 4 to PHP 5 (error in xml data)

The module display this error if I have PHP5 instead of PHP4

Code: Select all

An error occured during parsing XML data.

Hi

Please check if you have cURLS extension enable on your php.ini file.

Find

Code: Select all

;extension=php_curl.dll

and change to

Code: Select all

extension=php_curl.dll

Contact your host provider if you don't have access.

Also it's fundamental that you set full permissions (777) for cache directory and for file mod_gk_weather.xml

Cheers

yes I already have full permissions and the curl extension enabled

Are you sure you have 777 permissions on mod_gk_weather.xml?

What version of joomla and PHP version are u using?
(Be objective on which version of PHP5)

Yes I am sure!
I have Joomla 1.5.18 (latest) and PHP 5.2.13 with cURL support enabled (libcurl/7.20.1 OpenSSL/0.9.8b zlib/1.2.3 libidn/0.6.5)

I think that the problem might be on this line (helper.php)

Code: Select all

$current_conditions = $xml->document->weather[0]->current_conditions[0];

Seems that Joomla JSimpleXMLElement does not return the same values switching from php 4 to 5

I will investigate. Sorry for my poor english

Yes, with PHP5 the JFactory XML Parser return a different XML structure.
See the output for $xml->document (I can't paste here, it's too long), I cannot see humidity and wind conditions when parsing ($xml->loadString($this->content)) this reply:

Code: Select all

<?xml version="1.0"?><xml_api_reply version="1"><weather module_id="0" tab_id="0" mobile_row="0" mobile_zipped="1" row="0" section="0" ><forecast_information><city data="Cabras, Sardinia"/><postal_code data="Cabras,Sardinia"/><latitude_e6 data=""/><longitude_e6 data=""/><forecast_date data="2010-07-15"/><current_date_time data="2010-07-15 09:55:00 +0000"/><unit_system data="SI"/></forecast_information><current_conditions><condition data="Parzialmente nuvoloso"/><temp_f data="88"/><temp_c data="31"/><humidity data="Umidit?: 79%"/><icon data="/ig/images/weather/partly_cloudy.gif"/><wind_condition data="Vento: E a 19 km/h"/></current_conditions><forecast_conditions><day_of_week data="gio"/><low data="22"/><high data="29"/><icon data="/ig/images/weather/sunny.gif"/><condition data="Chiaro"/></forecast_conditions><forecast_conditions><day_of_week data="ven"/><low data="23"/><high data="31"/><icon data="/ig/images/weather/sunny.gif"/><condition data="Chiaro"/></forecast_conditions><forecast_conditions><day_of_week data="sab"/><low data="23"/><high data="30"/><icon data="/ig/images/weather/sunny.gif"/><condition data="Chiaro"/></forecast_conditions><forecast_conditions><day_of_week data="dom"/><low data="21"/><high data="28"/><icon data="/ig/images/weather/sunny.gif"/><condition data="Chiaro"/></forecast_conditions></weather></xml_api_reply>

OMG I've found it!

When you parse the XML response ($xml->loadString($this->content)) if it contains invalid non-xml characters like

Code: Select all

<humidity data="Umidit[color=#BF0000]?[/color]: 79%"/>

the resulting JSimpleXML object does not contains the relative object (humidity in this case) and

I have solved the problem temporarily changing the language from "it" (with accents) to "en" (without accents)

GK Weather must convert invalid characters from the google response into xml valid content-encoding to definitively solve this problem!

SOLUTION

open helper.php and add these 2 functions:

Code: Select all

 function XMLEntities($string)
    {
        $string = preg_replace('/[^x09x0Ax0Dx20-x7F]/e', '$this->_privateXMLEntities("$0")', $string);
        return $string;
    }

    function _privateXMLEntities($num)
    {
    $chars = array(
        128 => '€',
        130 => '‚',
        131 => 'ƒ',
        132 => '„',
        133 => '…',
        134 => '†',
        135 => '‡',
        136 => 'ˆ',
        137 => '‰',
        138 => 'Š',
        139 => '‹',
        140 => 'Œ',
        142 => 'Ž',
        145 => '‘',
        146 => '’',
        147 => '“',
        148 => '”',
        149 => '•',
        150 => '–',
        151 => '—',
        152 => '˜',
        153 => '™',
        154 => 'š',
        155 => '›',
        156 => 'œ',
        158 => 'ž',
        159 => 'Ÿ');
        $num = ord($num);
        return (($num > 127 && $num < 160) ? $chars[$num] : "&#".$num.";" );
    }

find

Code: Select all

if($xml->loadString($this->content))

replace

Code: Select all

if($xml->loadString($this->XMLEntities($this->content)))

you are welcome
I am testing and improving the code right now... think I will post some updates soon

see file attached, this is the final version

tested on php 4 and 5 and with english and italian language, we should check other encoding and languages

are you planning a new bugfixed release ?

I have same problem. When i checked the modules/mod_gk_weather/cache/mod_gk_weather.xml i found this:

Code: Select all

<HTML><HEAD><meta http-equiv="content-type" content="text/html;charset=utf-8">
<TITLE>302 Moved</TITLE></HEAD><BODY>

</BODY></HTML>

.

I deteted, saved and again.
In front-end the module show:

Warning: filesize() [function.filesize]: stat failed for /var/www/cache/mod_gk_weather.xml in /var/www/modules/mod_gk_weather/helper.php on line 182
An error occured during parsing XML data. Please try again.

I downloaded the helper.php from thispost but nothing.

LE. On localhost work, but online not. I have curl enabled: curl
cURL support enabled
cURL Information libcurl/7.18.0 OpenSSL/0.9.8g zlib/1.2.3.3 libidn/1.1

The modules/mod_gk_weather/cache/ is 777 and modules/mod_gk_weather/cache/mod_gk_weather.xml same 777
Can see the website: http://www.mercurcraiova.ro

Now work, but behind the module is shown this error:

Warning: filesize() [function.filesize]: stat failed for /var/www/cache/mod_gk_weather.xml in /var/www/modules/mod_gk_weather/helper.php on line 136

LE: Now work... i changed owner for modules/mod_gk_weather/cache/mod_gk_weather.xml and copy the modules/mod_gk_weather/cache/mod_gk_weather.xml file in cache/mod_gk_weather/mod_gk_weather.xml

In back-end at language i changed ro-RO in ro... and disable cache function.

today Google has changed url?

please, update GK Weather to fix latest problems!

Got the same problems with that module on my website. Where can I edit and update my module. Have got another website with the same module and it works - computer are crazy

Thanks for your support.

uhecht

Solution again

helper.php

Find www.google.con ... and replace it with www.google.de

And it works!

BUT: It only works in English. So far so good- but on a German website something strange. If I change en->de inside the module configuration all ä,ü, ö and so on are not printed in German.

However, it works quite normal and maybe there's a hint to print it in default German as I want.

uhecht

sometimes google can block your site for too many requests and gk weather displays the xml error
you can check this condition reading /modules/mod_gk_weather/cache mod_gk_weather.xml
