PHP Fatal error

Hello!

I recently started using your pluging and suddenly error logs increased (HTTP 500):

PHP message: PHP Fatal error: Call to a member function find() on a non-object in ../wp-content/plugins/follow-nofollow-control/nofollow-control.php on line 124″ while reading response header from upstream..

The issue affects to posts (or attachments pages that only consist of an image).

In order to fix it, just inclose function nofplg_display_content’s body in an if like this:

112 function nofplg_display_content($content){
113 if ($content) {
114 $html = str_get_html($content);
115 $options = get_option( ‘nofplg_item’ );
116
117 $site_url = get_bloginfo(‘url’); $parse_site = parse_url($site_url); $site_host = $parse_site[‘host’];
118
119 $follow = $options[‘follow’]; $follow_epl = explode(“,”,$follow); $follows = array();
120 foreach ($follow_epl as $fl) {$follows[] = trim($fl);}
121
122 $nofollow = $options [‘nofollow’]; $nofollow_epl = explode(“,”,$nofollow); $nofollows = array();
123 foreach ($nofollow_epl as $fl) {$nofollows[] = trim($fl);}
124
125 foreach ($html->find(“a”) as $a){
126 $rel = $a->rel;
127 $href = $a->href;
128 $parse = parse_url($href); $host = $parse[‘host’];
129
130 if ($options[‘default’]){ // the case default follow
131 if(in_array($host,$nofollows)) $a->rel = ‘nofollow’;
132 else $a->rel = ‘follow’;
133 }
134 else { // the case default nofollow
135 if(in_array($host,$follows) || $host == $site_host || $host ==”) $a->rel = ‘dofollow’;
136 else $a->rel = ‘nofollow’;
137 }
138
139 } // endforeach
140
141 return $html->save();
142 }
143
144 } // end function nofplg display content

And that’s all 🙂

Hope you can integrate this fix into your codebase and release a fixed version into wordpress plugin directory.

Thanks a lot for your work!
