    <p>If you mean javascript, you could go with the "advance to next input" method:</p> <p>Here's the HTML:</p> <pre><code>&lt;form id="ccform" action="cc_submit.php" method="post"&gt; &lt;fieldset id="ccnumber"&gt; &lt;input id="firstset" type="text" maxlength="4" /&gt; &lt;input id="secondset" type="text" maxlength="4" /&gt; &lt;input id="thirdset" type="text" maxlength="4" /&gt; &lt;input id="fourthset" type="text" maxlength="4" /&gt; &lt;/fieldset&gt; &lt;/form&gt; </code></pre> <p>And here's the JS:</p> <pre><code>var ccfields; function moveToNext(e) { var field = e.currentTarget; var chars = field.value.length; var setnumb = Number(field.id.substr(3,1)) - 1; if(chars &gt;= 4 &amp;&amp; setnumb &lt; 3) { ccfields[setnumb + 1].focus(); } } window.onload = function() { ccfields = document.getElementById("ccnumber").getElementsByTagName("input"); for (var i = 0; i &lt; ccfields.length; i++) { ccfields[i].onkeyup = moveToNext; } }; </code></pre> <p>Of course, you will want to add a function that checks for non-numbers and a function for taking the four fields and merging them into one string to pass back to the form. It also isn't a bad idea to use a js library like Jquery to ensure that events are handled the same way and simplify traversing through the inputs so you can use attributes like "name" without any confusion.</p> <p>But generally, if people see 4 fields, it makes it easier to type in their number, and for those visitors who think "ah nuts, I have to use my mouse for each number" they are (or at least I am) pleased that the page is smart enough to know to move to the next field.</p>

    2. COPlease no - this is a horrible idea. Sites that try to be 'helpful' and move to the next field when they think you've completed input in a field like this do two things. One, they make people who are tabbing to the next field because they know they are done skip fields and have to go back. And two, they make it darn near impossible to correct a field if you made a typo.

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.
