    <p>So I have this form, where I want to add a button which makes a function run.</p> <p>This is how my form looks like:</p> <pre><code>&lt;form action="" method="POST"&gt; CVR-nummer:&lt;br&gt; &lt;input name="cvr" id="cvr" type="text" value="" size="30"/&gt; &lt;button onclick="&lt;?php getinfo(); ?&gt;"&gt;Run the function&lt;/button&gt;&lt;br&gt; Navn:&lt;br&gt; &lt;input name="navn" type="text" value="&lt;?php if(isset($navn)) {echo $navn;} ?&gt;" size="30"/&gt;&lt;br&gt; Adresse:&lt;br&gt; &lt;input name="adresse" type="text" value="&lt;?php if(isset($adresse)) {echo $adresse;} ?&gt;" size="30"/&gt;&lt;br&gt; Postnummer:&lt;br&gt; &lt;input name="postnr" type="text" value="&lt;?php if(isset($postnr)) {echo $postnr;} ?&gt;" size="30"/&gt;&lt;br&gt; By:&lt;br&gt; &lt;input name="by" type="text" value="&lt;?php if(isset($by)) {echo $by;} ?&gt;" size="30"/&gt;&lt;br&gt; &lt;input type="submit" value="Registrer"/&gt; &lt;/form&gt; </code></pre> <p>And this is my function which uses an API</p> <pre><code>&lt;?php function getinfo() { $cvr = "12345678"; $api = json_decode(file_get_contents("http://cvrapi.dk/{$cvr}/"),true); $navn = $api['navn']; $adresse = $api['adresse']; $postnr = $api['postnr']; $by = $api['by']; } ?&gt; </code></pre> <p>When I click the button I want it to: 1. Get value of the cvr-field. 2. Validate cvr-field so it has exactly 8 numbers. 3. If validation OK it must set the variables. 4. The variables must be shown in the form.</p> <p>Any thoughts on how to do this?</p> <p><strong>UPDATE</strong></p> <pre><code>&lt;script type="text/javascript"&gt; function checkCVR() { var cvr = document.getElementById("cvr").value; var reg = new RegExp("^[0-9]{8}$"); if(!reg.test(cvr)) { document.getElementById("cvr_error").style.display = 'block'; document.getElementById("cvr_error").innerHTML = "CVR Error!"; } else { document.getElementById("cvr_error").style.display = 'none'; // var url = "http://cvrapi.dk/"+cvr+"/"; // var url = "http://haxify.org/result.php"; var url = "json.txt"; var xmlhttp = new XMLHttpRequest(); xmlhttp.open("GET", url, true); xmlhttp.onreadystatechange = function () { if (xmlhttp.readyState == 4 &amp;&amp; xmlhttp.status == 200) { var json = JSON.parse(xmlhttp.responseText); document.getElementById("navn").value = json["navn"]; document.getElementById("adresse").value = json["adresse"]; document.getElementById("postnr").value = json["postnr"]; document.getElementById("by").value = json["by"]; } }; xmlhttp.send(null); } } &lt;/script&gt; &lt;form action="" method="POST"&gt; CVR-nummer:&lt;br&gt; &lt;input name="cvr" id="cvr" type="text" value="" size="30"/&gt; &lt;input type="button" onClick="checkCVR()" value="Run the function" /&gt;&lt;br /&gt; &lt;span id="cvr_error" style="color:red;display:none;"&gt;&lt;/span&gt; Navn:&lt;br /&gt; &lt;input name="navn" id="navn" type="text" value="" size="30"/&gt;&lt;br /&gt; Adresse:&lt;br /&gt; &lt;input name="adresse" id="adresse" type="text" value="" size="30"/&gt;&lt;br /&gt; Postnummer:&lt;br /&gt; &lt;input name="postnr" id="postnr" type="text" value="" size="30"/&gt;&lt;br /&gt; By:&lt;br /&gt; &lt;input name="by" id="by" type="text" value="" size="30"/&gt;&lt;br /&gt; &lt;input type="submit" value="Registrer"/&gt; &lt;/form&gt; </code></pre> <p>This one actually works on one website but does not work on my own site. Is there any requirements for any software or something, or what can be the reaseon for this to not work on my specific website?</p> <p>Test: <a href="http://haxify.org/form_v4.php" rel="nofollow">http://haxify.org/form_v4.php</a></p>

    1. COUnfortunately it's not quite that easy. Keep in mind, that PHP gets executed on the server and your HTML page is on the clients computer. The browser never gets the php code and thus cannot run it. Your `getinfo()` doesn't actually echo or print anything. Therefore the browser will receive `<button onclick="">` (just one of the examples, why this wouldn't work). I suggest, that you start off with a html form based tutorial like [this](http://www.phpeveryday.com/articles/PHP-MySQL-Creating-Form-Insert-Data-P280.html) one.

    2. COAs @TimBodeit said, the difference between client-side and server-side makes what you're doing a difficoult task. You should try with a mix of javascript and php sending of variables to an indermediary script.

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.

SQuiL has stopped working due to an internal error.

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