    <p>I'm trying to grasp OOP and I decided to build a site that accesses a sql database. It's been working out great so far I have several tables, but I've run into a snag</p> <p>I access the database and create an object array with</p> <pre><code>$Dog_array = $sth-&gt;fetchAll(PDO::FETCH_CLASS, 'Dog'); </code></pre> <p>Simplified but my class looks like this.</p> <pre><code>class Dog { private $name; function get_name { return $this-&gt;name; } </code></pre> <p>list that build my table</p> <pre><code>function edit_table($Dog) { echo "&lt;table&gt;&lt;tr&gt;&lt;form action='update.php' method ='post'&gt;"; echo "&lt;input type='hidden' name='id' value='" . $id ."'&gt;"; echo "&lt;td&gt;". $Dog-&gt;get_id() ."&lt;/td&gt;"; ?&gt; &lt;td&gt;&lt;input type='text' name='rname' value="&lt;?php echo $Dog-&gt;get_rname(); ?&gt;"&gt;&lt;/td&gt; &lt;td&gt;&lt;input type='text' name='cname' value="&lt;?php echo $Dog-&gt;get_cname(); ?&gt;"&gt;&lt;/td&gt; &lt;td&gt;&lt;input type='text' name='dob' value="&lt;?php echo $Dog-&gt;get_dob(); ?&gt;"&gt;&lt;/td&gt; &lt;td&gt;&lt;input type='radio' name='gender' value='male' &lt;?PHP if($Dog-&gt;get_gender() == 'male'){ echo "checked=\"checked\""; } ?&gt; /&gt; Male &lt;input type='radio' name='gender' value='female' &lt;?PHP if($Dog-&gt;get_gender() == 'female'){ echo "checked=\"checked\""; } ?&gt; /&gt;Female&lt;/td&gt; &lt;td&gt;&lt;input type='text' name='sire' value="&lt;?PHP echo "builddropdown" ?&gt; "&gt;&lt;/td&gt; &lt;td&gt;&lt;input type='text' name='dam' value="&lt;?PHP drop_menu() ?&gt;"&gt;&lt;/td&gt; &lt;?php if ($Dog-&gt;get_available()) { $checked = "checked=\"checked\""; } else { $checked = NULL; echo "&lt;td&gt;&lt;input type=\"checkbox\"" . $checked . "name=\"available\" value=\"TRUE\"/&gt;&lt;/td&gt;"; if ($Dog-&gt;get_display()) { $checked = "checked=\"checked\""; } else { $checked = NULL; } echo "&lt;td&gt;&lt;input type=\"checkbox\"" . $checked . "name=\"display\" value=\"TRUE\"/&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;"; ?&gt; &lt;input type='submit' value='change image'/&gt;&lt;/form&gt; &lt;FORM METHOD="LINK" ACTION="upload.php"&gt; &lt;INPUT TYPE="submit" VALUE="Change Image Thumb"&gt; &lt;/FORM&gt; &lt;input type='submit' value='change image'/&gt;&lt;/form&gt; &lt;FORM METHOD="LINK" ACTION="upload.php"&gt; &lt;INPUT TYPE="submit" VALUE="Change Image Thumb"&gt; &lt;/FORM&gt; &lt;?php } ?&gt; &lt;input type='submit' value='update'/&gt;&lt;/form&gt; &lt;FORM METHOD="LINK" ACTION="index.php"&gt; &lt;INPUT TYPE="submit" VALUE="Back"&gt; &lt;/FORM&gt; &lt;?php } ?&gt; </code></pre> <p>My drop down</p> <pre><code>function drop_menu() { ?&gt; &lt;form name ="dropdown"&gt; &lt;select ="alldogs"&gt; &lt;?php foreach ($Dog_array as $Dogs) { ?&gt; &lt;option value="&lt;?php echo $Dogs-&gt;get_id() . "\"&gt;" . $Dogs-&gt;get_rname(); ?&gt;&lt;/option&gt; &lt;?php } ?&gt; &lt;/select&gt; &lt;/form&gt; &lt;? } </code></pre> <p>My drop down menu creates a list of all of the dogs.</p> <p>I get the error Invalid argument supplied for foreach</p> <p>I get why I get the error I just don't know how to clean this up so I don't have to pass my Object array into my edit_table function so I can pass it into drop down function . I thought about creating a child class but the menu is built from an array of the objects not one object so I don't know how to make this work either. New to forum posting, so feel free to recommend some corrections in how I ask for help.</p>

    1. COEither you pass the `$Dog_array` or get it as some global are the two ways I see this happening. Apart from this please check your html - 1) `drop_menu` call inside input 2) `drop_menu` definition closing the `form`, not starting the `select`

    3. COI think I corrected the html but I haven't looked it in great detail what exactly do you mean by "call inside input"

Querying!

 
Guidance
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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
