    <p>*<strong><em>edit have fixed this code - see inline comments marked EDIT *</em></strong></p> <p>I'm getting a few PHP debug notices when using the following code in a wordpress theme. It's my first attempt at using a PHP class, and it does work ok, but the debug notices concern me. I am calling the method in my PHP template thus:</p> <p><code>&lt;?php $getjobmeta-&gt;job_type(); ?&gt;</code> &amp; <code>&lt;?php $getjobmeta-&gt;post_types(); ?&gt;</code></p> <p>The debug notices are as follows:</p> <p><code>Notice: Undefined variable: post</code></p> <p><code>Notice: Trying to get property of non-object</code></p> <p>From the research I have done this looks like an issue with the class sometimes returning a non object, so i tried wrapping the 'echo' in <code>isset</code> and <code>is_object</code> but I just can't fix those notices.</p> <p>Here is the simplified code. For the sake of my sanity I could really use some help.</p> <pre><code> // define the class class getJobMeta { var $jobmeta_echo; // set a class variable to store our echo public function job_type() { // define a class function and make it public global $post // EDIT IN FIX if ( 'post' == get_post_type() ) { $jobtype = get_the_term_list( $post-&gt;ID, 'job-type', '&lt;span itemprop="employmentType"&gt;', ', ', '&lt;/span&gt;', 0 ); // 0 at end of arg signifies that we don't want links outputted } else { return ''; } echo $jobtype.$this-&gt;jobmeta_echo; } // end function job_type // define post type public function post_types() { global $post // EDIT IN FIX if ('post' == get_post_type()) { $posttype = get_the_term_list( $post-&gt;ID, 'channel', '&lt;strong class="channel-links clearfix"&gt;', ', ', '&lt;/strong&gt;', 1); // 1 means output as link } elseif ( 'blog' == get_post_type() ) { $posttype = '&lt;a href="/blog/" class="post-type-label"&gt;Blog&lt;/a&gt;'; } elseif ( 'type2' == get_post_type() ) { $posttype = '&lt;a href="/type2/" class="post-type-label"&gt;Type2&lt;/a&gt;'; } else { $posttype = ''; } echo $posttype.$this-&gt;jobmeta_echo; // EDIT TYPO } // end function posttype } // end getJobMeta class // set the class into a variable $getjobmeta = new getJobMeta; </code></pre> <p>Thanks Ben</p>

    1. COYou are using `$post->ID` in 2 places, which appear to be out of scope in your class. Perhaps these should be `$this->post->ID`? I don't know the internals of Wordpress. `$posttype = get_the_term_list( $post->ID, `

    2. CO"calling the class" is incorrect. You can call method. To call a method you should create an object or call static method. Can you provide more code? How $getjobmeta was defined?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
