    <p>I am trying to call a function in another .php file from this one by clicking a button, and I encountered this method elsewhere on the Internet, but I'm not sure if it works. I reduced the PHP code to simply printing something onscreen twice instead of calling another file, to demonstrate what is going wrong:</p> <pre><code>&lt;?php echo "hello"; ?&gt; &lt;?php echo &lt;&lt;&lt;END &lt;html&gt; &lt;body&gt; &lt;button type="button" onclick="handleButton()" id="button1"&gt;PHP Test&lt;/button&gt; &lt;script type="text/javascript"&gt; function handleButton() { document.getElementById("button1").innerHTML = "PHP Test&lt;?php echo 'HELLO';?&gt;"; } &lt;/script&gt; &lt;/body&gt; &lt;/html&gt; END; ?&gt; </code></pre> <p>Shouldn't pressing the button print "HELLO" on screen? Instead the HTML source for the button becomes:</p> <pre><code>&lt;button type="button" onclick="handleButton()" id="button1"&gt; PHP Test &lt;!--?php echo HELLO;?--&gt; &lt;/button&gt; </code></pre> <p>And nothing happens when the button is clicked. Since "hello" prints fine, why is the server commenting out the second php echo command?</p> <p>P.S.: I anticipate a lot of comments saying, "Why are you trying to do this in the first place?" I know I can make an HTML form that submits to a php file, but my goal here is to make multiple buttons onscreen, each leading to a different php file. I know that I could also make a form lead to a single php file that looks at which button on this screen was pressed, and calls the appropriate php file, but I'd like to avoid making another php file just to do that, if this can work. So unless I'm missing a more efficient approach, I'd prefer that we just stick to the subject of why the server is commenting out that PHP code. Thanks.</p>

    2. CONot really :-) The single-quotes don't help. The button just gets "<!--?php echo 'HELLO';?-->" added to it.

    3. COThere are just so many wrong things in the snippet you've posted above that I'm not entirely sure what it is that you're trying to achieve. Lets start by you quoting the strings properly. Are you sure you understand how HTML/JS and PHP work in terms of what runs on the client side (browser) and what runs on the server side (PHP)? Doesn't seem to me that you do.

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.
