Loads of notices generated by plugin

Your plugin currently generates 23 notices on every page load for different issues, mainly just because you are referencing variables as $foo[bar] instead of $foo[‘bar’] This makes it very difficult to debug a site for any issues as they are lost in the noise caused by your plugin. Developing with errors and warnings turned off is considered bad practice, so you may want to turn them on by default when developing. The undefined constant notices warn you of the potential that if there was a constant defined the same then your code would break. <?php define("key","otherkey"); $array['key'] = "My Blog"; $array['otherkey'] = "Something else"; echo $array['key']; // Outputs "My Blog" echo $array[key]; // Outputs "Something else" Notice: Undefined variable: post in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 219 Notice: Trying to get property of non-object in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 219 Notice: Undefined variable: post in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 220 Notice: Trying to get property of non-object in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 220 Notice: Use of undefined constant title - assumed 'title' in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 222 Notice: Use of undefined constant permalink - assumed 'permalink' in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 223 Notice: Use of undefined constant image - assumed 'image' in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 224 Notice: Undefined offset: 0 in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 194 Notice: Use of undefined constant blogname - assumed 'blogname' in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 225 Notice: Use of undefined constant description - assumed 'description' in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 226 Notice: Use of undefined constant language - assumed 'language' in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 227 Notice: Use of undefined constant appid - assumed 'appid' in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 228 Notice: Use of undefined constant adminid - assumed 'adminid' in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 229 Notice: Undefined variable: iametainfo in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 252 Notice: Use of undefined constant title - assumed 'title' in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 255 Notice: Use of undefined constant permalink - assumed 'permalink' in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 259 Notice: Use of undefined constant image - assumed 'image' in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 261 Notice: Use of undefined constant blogname - assumed 'blogname' in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 263 Notice: Use of undefined constant description - assumed 'description' in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 265 Notice: Use of undefined constant language - assumed 'language' in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 267 Notice: Use of undefined constant adminid - assumed 'adminid' in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 269 Notice: Use of undefined constant appid - assumed 'appid' in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 271 Notice: Use of undefined constant title - assumed 'title' in /path-to-site/wp-content/plugins/opengraph-and-microdata-generator/opengraph-microdata.php on line 273 [Moderator Note: Please post log files between backticks or use the code button.] http://wordpress.org/plugins/opengraph-and-microdata-generator/
