warning: preg_match.... bootstrap.inc on line 771 with /admin/build/translate page

exactly the same error

I started getting this error immediately after upgrading to Drupal 6.15.

Modifying bootstrap.inc worked for me! Thanks, Boran!

I have this error after installing Content Profile module, adding a new group (CCK) to the "profile" content type and go to the edit page of the group.

I had an older version of Conditional Fields, Not enabled. But thought I'd enable and update it.

This didn't work for me. bummer.

changing

return (preg_match('/^./us', $text) == 1) ? htmlspecialchars($text, ENT_QUOTES, 'UTF-8') : '';

to

return (preg_match('/^./us', $text) == 1) ? htmlspecialchars((string) $text, ENT_QUOTES, 'UTF-8') : '';

did.

I'm using RHEL5, which ships with PHP 5.1.6 In bootstrap.inc I see:

function check_plain($text) {
static $php525;

if (!isset($php525)) {
$php525 = version_compare(PHP_VERSION, '5.2.5', '>=');
}
// We duplicate the preg_match() to validate strings as UTF-8 from
// drupal_validate_utf8() here. This avoids the overhead of an additional
// function call, since check_plain() may be called hundreds of times during
// a request. For PHP 5.2.5+, this check for valid UTF-8 should be handled
// internally by PHP in htmlspecialchars().
// @see http://www.php.net/releases/5_2_5.php
// @todo remove this when support for either IE6 or PHP < 5.2.5 is dropped.

if ($php525) {
return htmlspecialchars((string)$text, ENT_QUOTES, 'UTF-8');
}

return (preg_match('/^./us', (string) $text) == 1) ? htmlspecialchars((string) $text, ENT_QUOTES, 'UTF-8') : '';

Since it appears to be checking for PHP 5.2, is it barfing on 5.1? With the fix as applied above, my site is horribly broken... images do not show up, all sorts of things are missing or broken. If I remove the "(string)" from those two lines, the site works again, but I'm again flooded with preg_match errors.

Hi guys, I did a backtrace using debug_print_backtrace() and the originating function sending an array to the check_plain function is "content_content_field_content_type_content_types()" which does a "t()" providing the Array on which the "htmlspecialchars()" function fails.

The involved modules (in my case) are a combination of Ctools and Panels.

Below I will include the first 6 entries of the backtrace log for anyone who wants it :) I have removed any long strings for easier readability.

For anyone who also wants to find out where the Array (or not-string) variable comes from on their installation do as follows:

Edit includes/bootstrap.inc around line 842 and add the fragment between "static $php525" and "if (isset($php525)) {" as follows:

function check_plain($text) {
  static $php525;

  if ( !is_string($text) && is_array($text) ) {
    echo "<pre>";
    print_r($text);
    debug_print_backtrace();
    echo "</pre>";
  }
  if (!isset($php525)) {
    $php525 = version_compare(PHP_VERSION, '5.2.5', '>=');
  }
  // We duplicate the preg_match() to validate strings as UTF-8 from
  // drupal_validate_utf8() here. This avoids the overhead of an additional
  // function call, since check_plain() may be called hundreds of times during
  // a request. For PHP 5.2.5+, this check for valid UTF-8 should be handled
  // internally by PHP in htmlspecialchars().
  // @see http://www.php.net/releases/5_2_5.php
  // @todo remove this when support for either IE6 or PHP < 5.2.5 is dropped.

  if ($php525) {
    return htmlspecialchars($text, ENT_QUOTES, 'UTF-8');
  }
  return (preg_match('/^./us', $text) == 1) ? htmlspecialchars($text, ENT_QUOTES, 'UTF-8') : '';
}

Have fun debugging.
