>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #1955992. --> >>> <p>I'm running Entity View Modes 7.x-1.0-beta3+9-dev on Drupal 7.19 and PHP 5.3.3. I have two custom view modes defined in <code>hook_entity_view_mode_info()</code> of two different modules. No other custom view modes are defined with the module (nothing in the variable).</p> <p>These are my hook implementations:</p> <div class="codeblock"> <pre><span style="color: #000000"><span style="color: #0000BB">&lt;?php<br></span><span style="color: #007700">function </span><span style="color: #0000BB">Aslideshow_entity_view_mode_info</span><span style="color: #007700">() {<br>&nbsp; </span><span style="color: #0000BB">$info </span><span style="color: #007700">= array();<br><br>&nbsp; </span><span style="color: #0000BB">$info</span><span style="color: #007700">[</span><span style="color: #DD0000">'node'</span><span style="color: #007700">][</span><span style="color: #DD0000">'slide'</span><span style="color: #007700">] = array(<br>&nbsp;&nbsp;&nbsp; </span><span style="color: #DD0000">'label' </span><span style="color: #007700">=&gt; </span><span style="color: #DD0000">'Slide'</span><span style="color: #007700">,<br>&nbsp;&nbsp;&nbsp; </span><span style="color: #DD0000">'custom settings' </span><span style="color: #007700">=&gt; </span><span style="color: #0000BB">1</span><span style="color: #007700">,<br>&nbsp; );<br><br>&nbsp; return </span><span style="color: #0000BB">$info</span><span style="color: #007700">;<br>}<br></span><span style="color: #0000BB">?&gt;</span></span></pre></div> <p>and</p> <div class="codeblock"> <pre><span style="color: #000000"><span style="color: #0000BB">&lt;?php<br></span><span style="color: #FF8000">/**<br>&nbsp;* Implements hook_entity_view_mode_info().<br>&nbsp;*/<br></span><span style="color: #007700">function </span><span style="color: #0000BB">Bsite_entity_view_mode_info</span><span style="color: #007700">() {<br>&nbsp; </span><span style="color: #0000BB">$info </span><span style="color: #007700">= array();<br><br>&nbsp; </span><span style="color: #0000BB">$info</span><span style="color: #007700">[</span><span style="color: #DD0000">'taxonomy_term'</span><span style="color: #007700">][</span><span style="color: #DD0000">'button'</span><span style="color: #007700">] = array(<br>&nbsp;&nbsp;&nbsp; </span><span style="color: #DD0000">'label' </span><span style="color: #007700">=&gt; </span><span style="color: #DD0000">'Button'</span><span style="color: #007700">,<br>&nbsp;&nbsp;&nbsp; </span><span style="color: #DD0000">'custom settings' </span><span style="color: #007700">=&gt; </span><span style="color: #0000BB">1</span><span style="color: #007700">,<br>&nbsp; );<br><br>&nbsp; return </span><span style="color: #0000BB">$info</span><span style="color: #007700">;<br>}<br></span><span style="color: #0000BB">?&gt;</span></span></pre></div> <p>Instead of getting the "button" view mode on taxonomy terms and the "slide" view mode on nodes, I end up with the slide view mode on both nodes and taxonomy terms.</p> <p>I debugged this and found the problem in <code>entity_view_mode_entity_info_alter()</code>.</p> <div class="codeblock"> <pre><span style="color: #000000"><span style="color: #0000BB">&lt;?php<br>&nbsp; </span><span style="color: #FF8000">// Because entity_get_info() merges in the default 'custom settings' value<br>&nbsp; // before it invokes hook_entity_info_alter(), we need to make sure that the<br>&nbsp; // custom view modes also have this value defined.<br>&nbsp; </span><span style="color: #007700">foreach (</span><span style="color: #0000BB">$view_mode_info </span><span style="color: #007700">as </span><span style="color: #0000BB">$entity_type </span><span style="color: #007700">=&gt; &amp;</span><span style="color: #0000BB">$view_modes</span><span style="color: #007700">) {<br></span><span style="color: #0000BB">?&gt;</span></span></pre></div> <p>In the loop above, the <code>$view_modes</code> variable is passed by reference through the loop.</p> <div class="codeblock"> <pre><span style="color: #000000"><span style="color: #0000BB">&lt;?php<br>&nbsp; </span><span style="color: #FF8000">// Add in the combined custom entity view modes which override the existing<br>&nbsp; // view modes in the entity information.<br>&nbsp; </span><span style="color: #007700">foreach (</span><span style="color: #0000BB">$view_mode_info </span><span style="color: #007700">as </span><span style="color: #0000BB">$entity_type </span><span style="color: #007700">=&gt; </span><span style="color: #0000BB">$view_modes</span><span style="color: #007700">) {<br></span><span style="color: #0000BB">?&gt;</span></span></pre></div> <p>When the next loop uses the same variable without unsetting it, it's still referencing the last value in the array from the previous loop. That's also the array in this loop. The first set of view modes is replacing the last set of view modes.</p> <p>This wasn't obvious to me, so excuse me if my explanation is long-winded.</p>
