CiviCRM Community Forums (archive)

When interviewing respondents, the Drupal log contains many entries with errors like ...

htmlspecialchars() expects parameter 1 to be string, array given in /var/www/citybibleforum/sites/all/modules/civicrm/packages/HTML/Common.php on line 144.
strlen() expects parameter 1 to be string, array given in /var/www/citybibleforum/sites/all/modules/civicrm/packages/HTML/QuickForm/element.php on line 238.

The second error is a call to HTML_QuickForm_element::getFrozenHtml() where the $this object is ...

(I've sanitised the actual phone number.) The code expects 'value' to be a String, but it is an Array[2] so the error is thrown. The outcome is that the 'value' attribute in the resulting HTML INPUT element is empty.
&nbsp;<input type="hidden" name="field[16063][phone-Primary-2]" value="" id="field_16063_phone-Primary-2" />
The interview uses a profile that includes the Primary work number and Primary mobile number. These end up being displayed correctly, despite this error.

It seems harmless - I can't see what the side-effects are - but it may be doing some damage somewhere,
