Phpcms2008 background article content changes do not display and blank problem fixed

gbk version of phpcms2008sp4 edit the article in the background found that the title, content, etc. do not show, as shown below:
The investigation found that phpcms2008sp4 htmlspecialchars parameter parameters used in the processing of the article information led to the loss of Chinese (php5.4 / 5.5 version need to complete the parameters). Direct use of htmlspecialchars ($ data [$ field], ENT_QUOTES) returns null, without any treatment.
 
Solution:
 
Look in data \ cache_model \ content_form.class.php
 
$ value = isset ($ data [$ field])? htmlspecialchars ($ data [$ field], ENT_QUOTES): '';
 
change into:
 
$ value = isset ($ data [$ field])? htmlspecialchars ($ data [$ field], ENT_QUOTES, 'GB2312'): '';
