After installation I have this errors

Warning: Invalid argument supplied for foreach() in /home/inets/www/sho2/library/cache/cache.php on line 6

When I push to any link I have this error:
Fatal error: Only variables can be passed by reference in /home/inets/www/sho2/library/cache/cache.php on line 7

Can anybody help me?

I think this problem is permissions on the cache directory. Some one else had a problem like this. If not try reinstalling.

I try reinstall - problem still exists.
On cache dir I have perm. 0777
Cache files in this dir created.

If I edit cache.php file in /library/cache/cache.php

In line 6 put cache path ->  foreach (glob('home/inets/www/sho2/cache/' . 'cache.*') as $file) {

I have this -> Warning: fopen(home/inets/www/sho2/cache/cache.language.1190280267) [function.fopen]: failed to open stream: No such file or directory in /home/inets/www/sho2/library/cache/cache.php on line 18

In cache dir are file with another filename -> cache.language.1190283614
 

cache.language.1190280267 filed to open
cache.language.1190283614 in cache

----
different file names

I found where is a problem:
I have PHP5.0.5 and array function end in PHP5.0.5 not work properly 
With this code shop start work.

function __construct() {   
foreach (glob(DIR_CACHE . 'cache.*') as $file) {
# NEW CODE #
                        $var=explode("/",$file);
                        $var=$var[count($var)-1];
$array = explode('.', $var);
                        ##########     
//$array = explode('.', end(explode('/', $file)));  //OLD CODE

      if ($array[2] < time()) {
unlink($file);
      }
    }
  }

All right - but what code needs to be exchanged with what of the code?

I don't remember what file I install opencart on another server with PHP 5.X and havn't problems.

Ok. But my server has php5.2.5. so it should be able to read it. Maybe its because you reinstalled that the problem was solved and not because of the server ? Could that be?

At first I install on server with PHP 4 and than I have a error.
At second I install opencart on another server with PHP 5 without any problems.

Problem found in array function -> End
http://lv2.php.net/manual/en/function.end.php
That function dont work on PHP4
Maybe need some libraries installed on server?!

I have the same problem. After install, these are the messages:

Warning: Invalid argument supplied for foreach() in c:\arquivos de programas\easyphp1-8\www\opencart\include\cache.php on line 10

Warning: Cannot modify header information - headers already sent by (output started at c:\arquivos de programas\easyphp1-8\www\opencart\include\cache.php:10) in c:\arquivos de programas\easyphp1-8\www\opencart\include\session.php on line 16

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at c:\arquivos de programas\easyphp1-8\www\opencart\include\cache.php:10) in c:\arquivos de programas\easyphp1-8\www\opencart\include\session.php on line 22

The website and its functions is working but the messages appear on the top of the page. I went to php.net and check that the function end works in php 4 - the version I am running on my server.
Does anybody knows what should I do to fix this issue? thanks

Ok, I found the problem...when the function search for cache files and there is no file, the glob() function returns an error.

I just check if there is any files in cache directory before call foreach files in the directory.

thanks

hi folks!
there is a BUG  .
Because glob()'ing an empty directory returns false, and so calling foreach (false as $value) will obviously break.

so I recomend you to fix it.
In your_store/library/cache/cache.php

replace function __construct()

Code: Select all

  	function __construct() {

		/**** OLD CODE *****
    	foreach (glob(DIR_CACHE . 'cache.*',GLOB_ONLYDIR) as $file) {
      		$array = explode('.', end(explode('/', $file)));

      		if ($array[2] < time()) {
				unlink($file);
      		}
    	}
		***** END OD OLD CODE *****/
		
		/**** BETTER (NOT BEST) - BUT WORKING NEW CODE ***/
		$files = glob(DIR_CACHE . 'cache.*',GLOB_ONLYDIR) or array();
		if ( is_array ( $files ) ) {
				foreach ($files as $file) {
					$array = explode('.', end(explode('/', $file)));
					if ($array[2] < time()) {
						unlink($file);
					}
				}
		}
		/* ***** END OF NEW CODE ***********************/
  	}

i've modified this and the same problem bother me,the host PHP version is : 5.8.8

If you have tried every option possible than you can always adjust your htaccess file by renaming it as .htaccess and adding this line in it:

php_flag display_errors off

Only use this option if the whole webshop works correctly but you only get those anoying warnings.
