Topic: common.php undefined variable string

[MeteoQc]

Hello guys,

Recently I encourted an error with my Ajax website that consist of this error (each time I load a page) in /etc/httpd/logs/error_log :

Code: [Select]

[error] [client *.156.194.*] PHP Notice:  Undefined variable: string in /var/www/html/meteo/common.php on line 430, referer: http://www.meteorimouski.ca/index.php
Line 430 of common.php is only this:

Code: [Select]

';
Lines 417 to 438 are :

Code: [Select]

# this function by mchallis prints (language selection flags or language selection text links)
# based on the setting $SITE['useLanguageFlags'] true or false
function print_language_selects_linear() {
 global $SITE;

 $string1 = '';
 $arr = $SITE['installedLanguages'];
 if (is_array($arr)){
    foreach ($arr as $k => $v) {

      if($SITE['useLanguageFlags'] == true) {
           $string .= '<a href="'. $_SERVER['PHP_SELF'] .'?lang='.$k.'" title="'. $v .'">
<img src="'. $SITE['imagesDir'] . 'flag-'. $k .'.gif" alt="'. $v .'" title="'. $v .'" border="0" /></a>
';
      }else{
           $k_print = $k;
           if ($_REQUEST['lang'] == $k) {
              $k_print = "[$k]";
 if (is_array($arr)){
                       [ ligne 417/748 (55%), col. 1/95 (1%), car. 15302/38337 (39%) ]

      if($SITE['useLanguageFlags'] == true) {
           $string .= '<a href="'. $_SERVER['PHP_SELF'] .'?lang='.$k.'" title="'. $v .'">
<img src="'. $SITE['imagesDir'] . 'flag-'. $k .'.gif" alt="'. $v .'" title="'. $v .'" border="0" /></a>
';

If someone have a clue of what is happening there, I will gladly accept some help!

I don't know if it's related, but sometimes my site don't react when I refresh the main page (clientraw.txt don't load) and i'm stuck on the main page. If I click another link in my site it doesn't work. Apache is misconfigurated maybe ? Or PHP ? My website is hosted on a VPS with 8Gb of RAM and 6 cores CPU access, so I don't think the problem is here.

Thanks,

Fred

I'm not sure this is the issue, but your Settings.php has

Code: [Select]

$SITE['langavail'] = array('fr',     // select languages to offer here.
// array('en', should be first entry on line above
// other languages with the Canada set can be enabled by installing language packs
//  'af',  // afrikaans
//  'ct', // 'catalan',
//  'dk', // 'danish',
//  'nl', // 'dutch',
//  'fi', // 'finnish',
  'fr', // 'french',
//  'de', // 'german',
//  'el', // 'greek',
//  'it', // 'italian',
//  'no', // 'norwegian',
//  'pl', // 'polish',
// 'pt', // 'portuguese',
//  'es', // 'spanish',
//  'se', // 'swedish',
); and should list French only once like this

Code: [Select]

$SITE['langavail'] = array('fr',     // select languages to offer here.
// array('en', should be first entry on line above
// other languages with the Canada set can be enabled by installing language packs
//  'af',  // afrikaans
//  'ct', // 'catalan',
//  'dk', // 'danish',
//  'nl', // 'dutch',
//  'fi', // 'finnish',
//  'fr', // 'french',
//  'de', // 'german',
//  'el', // 'greek',
//  'it', // 'italian',
//  'no', // 'norwegian',
//  'pl', // 'polish',
// 'pt', // 'portuguese',
//  'es', // 'spanish',
//  'se', // 'swedish',
);

Thank you for your quick reply.

I have done what you said but it doesn't change anything, the error is still there. I will leave it that way anyway.

BUT, I have changed this line:

Code: [Select]

$SITE['allowLanguageSelect'] = true;
To this:

Code: [Select]

$SITE['allowLanguageSelect'] = false;
And the error doesn't comes up anymore!

Since you only wish to offer French on the site, your fix is likely the best one

It may be that the trailing comma on

Code: [Select]

$SITE['langavail'] = array('fr',     // select languages to offer here. is causing a null second entry in the array.  Changing it to

Code: [Select]

$SITE['langavail'] = array('fr'      // select languages to offer here. and turning on the language select again may stop the error message.

Best regards,
Ken

I have deleted the comma and set allowLanguageSelect back to 'true' and the error re-apeared 

I will just leave allowLanguageSelect to 'false' as it resolved my problem.

Have a nice day, and thank you for your help

FYI, the logged item isn't really an error; it's a notice and changing the way php logs to apache via the php.ini file will eliminate the notice entries.  If you have a way to do that.

Not saying you even want to, but it's an option.  I turned my notice entries off because it wrote too much to the error logs when notices aren't 'technically' errors.
