    <p>I'm using idealforms from elclanrs and I have a select which is filled from a database. OnChange I want to update the value of the input fields with information from the database. In this case, firstname, lastname. I tried it with AJAX but that didn't work out because when the form values where getting renewed, the whole idealforms makeup of the form vanishes.</p> <p>I looked through stackoverflow and saw it was a fairly common problem but I still can't seem to work it out. I used <a href="https://stackoverflow.com/questions/5457739/change-value-of-input-onchange">this</a> and it didn't work, maybe because I placed it in the wrong order? </p> <p>This is my code:</p> <pre><code> &lt;form id="my-form" action="EditAccountHandler.php" method="post"&gt; &lt;?php include 'conn/dbConnect.php'; echo '&lt;div&gt;&lt;label&gt;Gebruikers&lt;/label&gt;&lt;select id="gebruiker" selected="$sUsername" name="selectedUser" onchange="updateInput(this.value)"&gt;'; $sqEditUser = mysql_query("SELECT * FROM account a, persoon p WHERE a.idSuper = p.idUser", $con); while($row = mysql_fetch_array($sqEditUser)) { $iIdUser = $row['idUser']; $sFirstname = $row['Voornaam']; $sLastname = $row['Achternaam']; $sUsername = "{$sLastname}, {$sFirstname}"; echo "&lt;option value='$iIdUser'&gt;$sUsername&lt;/option&gt;"; } echo "&lt;/select&gt;&lt;/div&gt;"; ?&gt; &lt;script&gt; function updateInput(&lt;?= json_encode($sFirstname); ?&gt;) { document.getElementById("naam").value = &lt;?php echo json_encode($sFirstname); ?&gt;; } &lt;/script&gt; &lt;div&gt;&lt;label&gt;Voornaam&lt;/label&gt;&lt;input id="naam" name="naam" type="text"/&gt;&lt;/div&gt; &lt;div&gt;&lt;label&gt;Achternaam&lt;/label&gt;&lt;input id="anaam" name="anaam" type="text"/&gt;&lt;/div&gt; &lt;div&gt; &lt;button id="reset" type="button"&gt;Reset&lt;/button&gt; &lt;button type="submit"&gt;Wijzigen&lt;/button&gt; &lt;/div&gt; &lt;/form&gt; </code></pre> <p>This is what I'm trying to achieve: <a href="http://tinypic.com/r/33z92k7/6" rel="nofollow noreferrer">Example picture</a></p> <p>I'm not sure about what I am doing wrong. Can yo guys help me?</p> <p><strong>Edit</strong><br> Removed code that was double in comparison with the first codesnippet.<br> Added echo<br> Removed action="EditAccountHandler.php"<br> Added idealforms validation code Replaced with final code </p> <pre><code>&lt;div id="main"&gt; &lt;h3&gt;Wijzig Account&lt;/h3&gt;&lt;br /&gt; &lt;form id="myselect" action="" method="post"&gt; &lt;div&gt; &lt;label&gt;Gebruikers&lt;/label&gt;&lt;select id="gebruiker" selected="$sUsername" name="selectedUser" onchange="this.form.submit()"&gt; &lt;?php include 'conn/dbConnect.php'; $sqUser = mysql_query("SELECT * FROM account a, persoon p WHERE a.idSuper = p.idUser", $con); while($row = mysql_fetch_array($sqUser)) { $iIdUser = $row['idUser']; $sFirstname = $row['Voornaam']; $sLastname = $row['Achternaam']; $sUsername = "{$sLastname}, {$sFirstname}"; echo "&lt;option value='$iIdUser'&gt;$sUsername&lt;/option&gt;"; } ?&gt; &lt;/select&gt; &lt;/div&gt; &lt;/form&gt; &lt;script&gt; var options = { onFail: function(){alert('Selecteer een persoon')}}; var $myform1 = $('#myselect').idealforms(options).data('idealforms'); $myform1.focusFirst(); &lt;/script&gt; &lt;?php if(!empty($_POST['selectedUser'])) { $sqGetUser = mysql_query("SELECT * FROM persoon WHERE idUser = '$_POST[selectedUser]'", $con); while($row = mysql_fetch_array($sqGetUser)) { $sFname = $row['Voornaam']; $sLname = $row['Achternaam']; } ?&gt; &lt;form id="my-form" action="EditAccountHandler.php" method="post"&gt; &lt;div&gt;&lt;label&gt;Voornaam&lt;/label&gt;&lt;input id="naam" name="naam" value="&lt;?php echo htmlspecialchars($sFname); ?&gt;" type="text"/&gt;&lt;/div&gt; &lt;div&gt;&lt;label&gt;Achternaam&lt;/label&gt;&lt;input id="anaam" name="anaam" value="&lt;?php echo htmlspecialchars($sLname); ?&gt;" type="text"/&gt;&lt;/div&gt; &lt;div&gt; &lt;label&gt;Rechten&lt;/label&gt; &lt;label&gt;&lt;input type="radio" name="rechten" value="Administrator"/&gt;Administrator&lt;/label&gt; &lt;label&gt;&lt;input type="radio" name="rechten" value="Contentmanager"/&gt;Contentmanager&lt;/label&gt; &lt;label&gt;&lt;input type="radio" name="rechten" value="Administratie"/&gt;Administratie&lt;/label&gt; &lt;label&gt;&lt;input type="radio" name="rechten" value="Medewerker"/&gt;Medewerker&lt;/label&gt; &lt;label&gt;&lt;input type="radio" name="rechten" value="Klant" checked/&gt;Klant&lt;/label&gt; &lt;label&gt;&lt;input type="radio" name="rechten" value="Gast"/&gt;Gast&lt;/label&gt; &lt;label&gt;&lt;input type="radio" name="rechten" value="MedeKlant"/&gt;MedeKlant&lt;/label&gt; &lt;/div&gt; &lt;div&gt; &lt;button id="reset" type="button"&gt;Reset&lt;/button&gt; &lt;button type="submit"&gt;Wijzigen&lt;/button&gt; &lt;/div&gt; &lt;/form&gt; &lt;/div&gt; &lt;/div&gt; &lt;script&gt; var options = { onFail: function() { alert( 'Vul alle velden correct in.' ) }, inputs: { 'anaam': { filters: 'required name', }, 'naam': { filters: 'required name', }, } }; var $myform = $('#my-form').idealforms(options).data('idealforms'); $('#reset').click(function(){ $myform.reset().fresh().focusFirst() }); $myform.focusFirst(); &lt;/script&gt; &lt;?php } ?&gt; </code></pre>

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.
