    <p>I have searched but could not get solution on this issue.</p> <p>I am working on an application which will generate unknown number of items and have users select the quantity from a drop down against each item. Eg.</p> <pre><code>Item(s) | price | Select qty Rice 23 3 Beans 22 4 Eggs 52 5 ... ... ... unknown </code></pre> <p>Please, how can I capture the above in an array and also calculate the total value for all selected items and corresponding fees?</p> <p>I have the following HTML code:</p> <pre><code>&lt;form id='form1' name='form1' method='post' action='item_calc.php'&gt; &lt;?php ..... while($t_row = mysql_fetch_assoc($get_items)) { echo "&lt;p&gt;&lt;label&gt;$t_row['$item_name'] &lt;input type='text' READONLY name='item_price[]' value='$t_row['$item_price']' /&gt;&lt;/label&gt; &lt;input type='text' READONLY name='item_fees[]' value='$t_row['$item_fee']' /&gt; &lt;select name="item_qty"&gt; &lt;option value="1"&gt; &lt;option value="2"&gt; &lt;option value="3"&gt; &lt;option value="4"&gt; &lt;option value="5"&gt; &lt;/select&gt; &lt;/p&gt;&lt;p&gt;"; } echo "&lt;label&gt;&lt;input type='submit' name='submit' value='Submit' /&gt;&lt;/label&gt;&lt;/p&gt; &lt;/form&gt;"; </code></pre> <p>Please, how can I get item_price[] + item_fees[] * item_qty for all selected items?</p> <p>This is what I have tried:</p> <pre><code>for ($i = 0; $i &lt; count($_POST['item_price']); $i++) { // Do something here with $_POST['checkbx'][$i] foreach ($_POST['item_fees'] as $tkey =&gt; $tvalue) { //echo "Key: $tkey; Value: $tvalue&lt;br&gt;"; } foreach ($_POST['item_price'] as $pkey =&gt; $pvalue) { //echo "Key: $pkey; Value: $pvalue&lt;br&gt;"; } $total = $tvalue + $pvalue; } echo $total; </code></pre>

    3. CONot unknown but variable I think. So you could get the values of `item_price`, see as well [`array_values`](http://php.net/array_values).

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).
