    <p>I am having an issue validating that a field is empty or full. The code below will help.</p> <p>The below is not the whole piece of my form, just the part you need to know. <b>HTML:</b></p> <pre><code>&lt;form action="" method="post" id="all_message"&gt; &lt;ul&gt; &lt;li&gt; &lt;label for="subject"&gt;Subject&lt;/label&gt;&lt;br /&gt; &lt;select id="No_dropdown" name="Dropown_select"&gt; &lt;option value="Request for quote"&gt;Request for quote&lt;/option&gt; &lt;option value="Service inquiries"&gt;Service inquiries&lt;/option&gt; &lt;option value="Other"&gt;Other&lt;/option&gt; &lt;/select&gt; &lt;/li&gt; &lt;li&gt; &lt;input type="submit" value="Send" name="submit" /&gt; &lt;/li&gt; &lt;/ul&gt; &lt;/form&gt; </code></pre> <p>I use this script to make a no selection on the select option above. <b>Javascript</b></p> <pre><code>&lt;script language="javascript" type="text/javascript"&gt; document.getElementById("No_dropdown").selectedIndex = -1; &lt;/script&gt; </code></pre> <p>This is not the whole PHP for it, just the part I'm having trouble with. <b>PHP:</b></p> <pre><code>$subject = $_POST['Dropown_select']; if (empty($name) === true || empty($email) === true || empty($phone) === true || !($subject === "Other" || "Service inquiries" || "Request for quote") || empty($message) === true ) </code></pre> <p>This is the part I am having troubles with:</p> <pre><code>!($subject === "Other" || "Service inquiries" || "Request for quote") </code></pre> <p>I need that part to see if one of the 'dropdowns' is selected and if not give an error.</p>

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).
