    <p>I'm trying to iterate a bunch of SELECT OPTION html drop-down fields and from the ones that are NOT empty, take the values and add a hidden field for a PAYPAL shopping cart.</p> <p>My problem is that for some reason, the variable "curitem" is not passed inside the <code>each</code> function and I can't add the hidden field like they should. All I get is "NaN" or "undefined".</p> <p>What PAYPAL expects is: item_name_1, item_name_2, etc. All numbers must iterate by +1.</p> <p>How can I do this? </p> <p>Thanks a bunch in advance</p> <pre><code>var curitem; $.each($("select"), function(index, item) { var attname = $(this).attr("name"); var nom = $(this).attr("data-nom"); var prix = $(this).attr("data-val"); var partname = attname.substring(0, 1); var qte = $(this).val(); // i want all my &lt;select option&gt; items that the NAME start with "q" AND have a value selected if (partname == "q" &amp;&amp; isNaN(qte) == false &amp;&amp; qte &gt; 0) { // item name var inp2 = document.createElement("input"); inp2.setAttribute("type", "hidden"); inp2.setAttribute("id", "item_name_"+curitem); inp2.setAttribute("name", "item_name_"+curitem); inp2.setAttribute("value", nom); // amount var inp3 = document.createElement("input"); inp3.setAttribute("type", "hidden"); inp3.setAttribute("id", "amount_"+curitem); inp3.setAttribute("name", "amount_"+curitem); inp3.setAttribute("value", prix); // qty var inp4 = document.createElement("input"); inp4.setAttribute("type", "hidden"); inp4.setAttribute("id", "quantity_"+curitem); inp4.setAttribute("name", "quantity_"+curitem); inp4.setAttribute("value", qte); // add hidden fields to form document.getElementById('payPalForm').appendChild(inp2); document.getElementById('payPalForm').appendChild(inp3); document.getElementById('payPalForm').appendChild(inp4); // item number curitem = curitem + 1; } }); </code></pre>

    3. COWhy not use `index` instead? And `$('select').each(function(index, item) {...})` might be nicer.

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.
