    <p>I am using AJAX to track the number of clicks of a button on my site and I would like to display that value on the page as well. Currently the tracking is working great and the number of clicks is being printed to a document called clicks.txt and I was wondering how I could go about reading the value from that text file and printing it to the page.</p> <p>I tried searching SO and Google for an answer, but I guess I can't think of how to word it properly because the answers I have found so far have been unrelated to what I'm trying to do.</p> <p>Here is the AJAX included in index.php</p> <pre><code>&lt;script type="text/javascript"&gt; function getXMLHttp() { var xmlHttp try { xmlHttp = new XMLHttpRequest(); } catch(e) { try { xmlHttp = new ActiveXObject("Msxml2.XMLHTTP"); } catch(e) { try { xmlHttp = new ActiveXObject("Microsoft.XMLHTTP"); } catch(e) { return false; } } } return xmlHttp; } function MakeRequest() { var xmlHttp = getXMLHttp(); xmlHttp.onreadystatechange = function() { if(xmlHttp.readyState == 4) { HandleResponse(xmlHttp.responseText); } } xmlHttp.open("GET", "counter.php", true); xmlHttp.send(null); } function HandleResponse(response) { document.getElementById('ResponseDiv').innerHTML = response; } &lt;/script&gt; </code></pre> <p>Here is the external PHP(counter.php) I am using to track the button clicks:</p> <pre><code>&lt;?php $clicks = file_get_contents("clicks.txt"); $clicks++; $fp = fopen("clicks.txt", "w+"); while ( !flock($fp, LOCK_EX) ) { usleep(500000); // Delay half a second } fwrite($fp, $clicks); fclose($fp); flock($fp, LOCK_UN); ?&gt; </code></pre> <p>Thanks in advance!</p>

    2. COThat's what I figured too, but since $clicks is set in a separate file(counter.php), I'm not sure how to go about it.

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.
