1. Make sure you're using Token 6.x-1.15 or newer.
2. Double check your admin/reports/status page for a 'Duplicate token' warning. If you see one, please report it back here.

What other modules are you using that have token implementations?

They have to be duplicates at the same level.

You are likely going to need to do something like this:

in pathauto.inc change:

  $tokens = token_prepare_tokens($full->tokens);
  $values = pathauto_clean_token_values($full, $options);

to be:

  $tokens = token_prepare_tokens($full->tokens);
  watchdog('debug', var_export($tokens, true));
  $values = pathauto_clean_token_values($full, $options);

Then look in the watchdog for an array at a level where everything else is strings.

Nothing in there looks like a problem to me. I'm stumped.

We need to debug the token values, not the token names. Change the line from:
watchdog('debug', var_export($tokens, true));
to
watchdog('debug', var_export($full->values, true));

(my bad)

So it looks like the [small] token is getting defined twice. The [termpath] and [termpath-raw] tokens should be arrays by design and not actually be causing problems.

You'll have to make sure you're using the latest Token module and then go to admin/reports/status to find out which modules are at fault for defining the [small] token more than once.

I get this error every time I edit page of a content type which uses taxonomy. No error is returned if I edit page which doesn't use taxonomy.

I modified the pathauto.inc to get the debug, but not sure waht to look for:

I'm using the patch for i18n by pokurek http://drupal.org/node/290421#comment-3763178

Not sure if it's related but this error has appeared at the same time than this one, on Panels page only in translated language:

htmlspecialchars() expects parameter 1 to be string, array given dans /home/XXXX/sites/includes/bootstrap.inc à la ligne 857.

subscribing.

I've just updated to Token 6.x-1.15 and Pathauto 6.x-1.5 and I still see the error in the logs

I had the same problem and never found the token duplication.

I solved adding an hack code inside pathauto.inc file:

function pathauto_clean_token_values($full) {
  $replacements = array();
  foreach ($full->values as $key => $value) {
	if (is_array($value)) $value = (string)$value[0]; // <-- THIS IS THE LINE I ADDED
    // Only clean non-path tokens.
    $token = $full->tokens[$key];
    if (!preg_match('/(path|alias|url|url-brief)(-raw)?$/', $token)) {
      $replacements[$token] = pathauto_cleanstring($value);
    }
    else {
      $replacements[$token] = $value;
    }
  }
  return $replacements;
}

I simply transform the array in a string getting the first element inside of it.

I hope this may help anybody.

Bye!

@gianfrasoft: You are not using the latest Pathauto release that accounts for some path-style tokens returning a valid array.

@Dave Reid - I'm using the latest: 6.x-1.5

@gianfrasoft: No you're not as that function as defined in 6.x-1.5 is:

function pathauto_clean_token_values($full, $options = array()) {
  $replacements = array();
  foreach ($full->values as $key => $value) {
    $token = $full->tokens[$key];
    if (strpos($token, 'path') !== FALSE && is_array($value) && !empty($options['pathauto'])) {
      // If the token name contains 'path', the token value is an array, and
      // the 'pathauto' option was passed to token_get_values(), then the token
      // should have each segment cleaned, and then glued back together to
      // construct a value resembling an URL.
      $segments = array_map('pathauto_cleanstring', $value);
      $replacements[$token] = implode('/', $segments);
    }
    elseif (preg_match('/(path|alias|url|url-brief)(-raw)?$/', $token)) {
      // Token name matches an URL-type name and should be left raw.
      $replacements[$token] = $value;
    }
    else {
      // Token is not an URL, so it should have its value cleaned.
      $replacements[$token] = pathauto_cleanstring($value);
    }
  }
  return $replacements;
}

which has additional code to handle an array if $options['pathauto'] is TRUE.

@Dave Reid - You were right, thank you!

In my files there was a little chaos, version 1.5 of pathauto solved the problem. Bye.

The problem occurred againd during a node_save API call, right using Pathauto ver. 6.x-1.5. It seems to be a curse.

I re-added the same code posted in my comment #20 and I solved again definitively.

Here is the code, again:

function pathauto_clean_token_values($full, $options = array()) {
  $replacements = array();
  foreach ($full->values as $key => $value) {
	if (is_array($value)) $value = (string)$value[0]; // <-- TAKE A LOOK AT HERE !!!!!
    $token = $full->tokens[$key];
    if (strpos($token, 'path') !== FALSE && is_array($value) && !empty($options['pathauto'])) {
      // If the token name contains 'path', the token value is an array, and
      // the 'pathauto' option was passed to token_get_values(), then the token
      // should have each segment cleaned, and then glued back together to
      // construct a value resembling an URL.
      $segments = array_map('pathauto_cleanstring', $value);
      $replacements[$token] = implode('/', $segments);
    }
    elseif (preg_match('/(path|alias|url|url-brief)(-raw)?$/', $token)) {
      // Token name matches an URL-type name and should be left raw.
      $replacements[$token] = $value;
    }
    else {
      // Token is not an URL, so it should have its value cleaned.
      $replacements[$token] = pathauto_cleanstring($value);
    }
  }
  return $replacements;
}

Unless it's a patch, the status should not be "needs review."

Since this fixes the symptom (noise in Pathauto) rather than the bug (buggy code in some other module) it won't be committed to Pathauto.

Please search for which module is causing the problem and file a bug with it.

I'm not sure if this provides any insight at all, but I was getting this same error (although the error was on line 441). I was also getting the following error along with it:

warning: mb_eregi_replace() expects parameter 3 to be string, array given in all/modules/pathauto/pathauto.inc on line 236. (as addressed in http://drupal.org/node/324404).

The node I was creating used the CCK field module "Phone Number" (http://drupal.org/project/cck_phone), and I found that when I disabled this module the errors went away. I'm not sure if this will shed any insight into the problem, but I figured I'd post my findings here anyway. I will also post this finding over on the "Phone Number" issues cue.

I had the same problem with the Phone Number module (http://drupal.org/project/cck_phone). I tried the 6.x-1.x-dev version and the error messages had disappeared.

@buda: Good god, the phone module provides it's tokens under the names 'raw' and 'formatted' which likely would conflict if any other token modules defines those tokens either in a node or global context. Horrible, horrible token name choices...

Please file an issue in phone.module to get those tokens properly namespaced.
