    <p>Below is a function that outputs a form with existing users from a database, with checkboxes and a submit button. The user choose one or several users to be removed and submits the form. What i'm working on right now is to implement a confirmation box in js ("Are you sure you want to remove..."), which shall contain the users that the user wants to remove.</p> <p>By that reason I'm putting in the usernames in a hidden field that the js function will retrieve the username(s) from. The problem is that not only the usernames are put into the hidden input fields value attribute, but also several input fields as well (!?). If I hard code in for example 'username1,username2' in the attribute it works as it should, but not if I use the variable $users.</p> <pre><code> public function ShowUsers($userArray) { $userIdArray = $userArray[0]; $userNameArray = $userArray[1]; $users = implode(",", $userNameArray); echo $users; // username1,username2... $nrOfUsers = count($userIdArray); for ($i = 0; $i &lt; $nrOfUsers; $i++) { $users .= "&lt;label for='$userIdArray[$i]'&gt; $userNameArray[$i] &lt;input type='checkbox' name='$this-&gt;_checkBox' value='$userIdArray[$i]' /&gt;&lt;br/&gt; &lt;/label&gt;"; } $userList = "&lt;div class='userList'&gt; &lt;form id='form3' method='post' action=''&gt; &lt;fieldset&gt; &lt;p&gt;Existing users&lt;/p&gt; $users &lt;input type='hidden' value='$users' /&gt; &lt;input type='submit' id='$this-&gt;_submitRemove' name='$this-&gt;_submitRemove' Value='Ta bort' /&gt; &lt;/fieldset&gt; &lt;/form&gt; &lt;/div&gt;"; return $userList; } </code></pre> <p>The output is the following:</p> <pre><code>&lt;input type='hidden' value='username1,username2&lt;label for='47'&gt; username1 &lt;input type='checkbox' name='check[]' value='47' /&gt;&lt;br/&gt; &lt;/label&gt;&lt;label for='50'&gt; username2 &lt;input type='checkbox' name='check[]' value='50' /&gt;&lt;br/&gt; &lt;/label&gt;' /&gt; </code></pre> <p>I just don't get it why this happens? The content of $users (in this case 'username1' and 'username2') is there as expected, but why is the input and label tags put into the value attribute?</p>

    1. COBecause you're altering the $users variable above in the for loop, appending more content to 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.
