    <p>I'm having trouble with more then one submit Buttons in HTML &amp; PHP, i tried to code a GUI for a web-based calculator. That's realy easy, but the function in php isn't so easy. So i have this simple GUI with 6 submit buttons:</p> <pre><code>&lt;?php $output= isset($_POST['output']) ? $_POST['output'] : ""; function calc(){ //calculate... } ?&gt; &lt;!DOCTYPE html&gt; &lt;html lang="de"&gt; &lt;head&gt; &lt;meta charset="utf-8" /&gt; &lt;title&gt;Calc&lt;/title&gt; &lt;style type="text/css"&gt; .bwidth { width: 100%; } &lt;/style&gt; &lt;/head&gt; &lt;body&gt; &lt;form action="calc.php"&gt; &lt;h1&gt; &lt;u&gt;MY Own Calculator&lt;/u&gt; &lt;/h1&gt; &lt;table border="3px" type="box" cellspacing="5px" width="250px"&gt; &lt;tr style="height: 24px;"&gt; &lt;td colspan="3"&gt;&lt;input type="text" name="&lt;?php $ausgabe ?&gt;" value="0" style="width: 98%;" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;input class="bwidth" type="submit" name="1" value="1" /&gt;&lt;/td&gt; &lt;td&gt;&lt;input class="bwidth" type="submit" name="2" value="2" /&gt;&lt;/td&gt; &lt;td&gt;&lt;input class="bwidth" type="submit" name="3" value="3" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;input class="bwidth" type="submit" name="minus" value="-" /&gt;&lt;/td&gt; &lt;td&gt;&lt;input class="bwidth" type="submit" name="plus" value="+" /&gt;&lt;/td&gt; &lt;td&gt;&lt;input class="bwidth" type="submit" name="enter" value="=" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/form&gt; &lt;/body&gt; </code></pre> <p>Now how I can differentiate these many submit buttons? It's even possible to have more than one submit button? I tried it to seperate the buttons by the value... but it didn't work.</p> <p>And sb has an idea how i can add a value to an existing value in the textfield? So i can push button 1 and it will write 1 in the textfield and when i will push button 2 it will add the number 2 so it will a "12"?</p> <p>Thanks for all suggestions!</p>

    1. COI think what you really need is few normal button, and a javascript method.

    2. COYeah, I'd second that. You don't need php to write this, just turn all the buttons to type="button" and use jquery/javascript to write the functions that support the buttons. Also, add ids to all form elements so that you can call them from the javascript using the id's as references.

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).
