    <p><strong>Purpose:</strong> Call a PHP function to read data from a file and rewrite it. I used PHP only for this purpose - FileIO - and I'm new to PHP.</p> <p><strong>Solution?</strong> I tried through many forums and knew that we cannot achieve it normal way: onClick event > call function. How can we do it, are there other ways, particularly in my case? My HTML code and PHP code is on the same page: Admin.php. This is HTML part:</p> <pre><code>&lt;form&gt; &lt;fieldset&gt; &lt;legend&gt;Add New Contact&lt;/legend&gt; &lt;input type="text" name="fullname" placeholder="First name and last name" required /&gt; &lt;br /&gt; &lt;input type="email" name="email" placeholder="etc@company.com" required /&gt; &lt;br /&gt; &lt;input type="text" name="phone" placeholder="Personal phone number: mobile, home phone etc." required /&gt; &lt;br /&gt; &lt;input type="submit" name="submit" class="button" value="Add Contact" onClick="" /&gt; &lt;input type="button" name="cancel" class="button" value="Reset" /&gt; &lt;/fieldset&gt; &lt;/form&gt; </code></pre> <p>This is PHP part:</p> <pre><code>function saveContact() { $datafile = fopen ("data/data.json", "a+"); if(!$datafile){ echo "&lt;script&gt;alert('Data not existed!')&lt;/script&gt;"; } else{ ... $contact_list = $contact_list . addNewContact(); ... file_put_contents("data/data.json", $contact_list); } fclose($datafile); } function addNewContact() { $new = '{'; $new = $new . '"fullname":"' . $_GET['fullname'] . '",'; $new = $new . '"email":"' . $_GET['email'] . '",'; $new = $new . '"phone":"' . $_GET['phone'] . '",'; $new = $new . '}'; return $new; } </code></pre> <p>Have a look at these code, I want to call saveContact when people click on Add Contact button. We can reload page if need so. FYI, I use JQuery, HTML5 in page as well. Thanks,</p>

Querying!

 
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).
