Body
<p>i have a php page where i would be able to subtract two values from which one is fetched from mysql database and another one is entered by user itself. What i want exactly is while entering the value in second input field the entered value should be subtracted from first input value calling from database and the subtracted value should be visible in another input... Code is...</p> <pre><code> <html> <head> <style> td {font-size:13px;} </style> <script src="jquery-1.8.3.js"></script> <script type="text/javascript"> $(function(){ $('input').each(function() { $(this).keyup(function(){ calculatedis($(this)); }); }); }); function calculatedis(src) { var sub = 0; var sumtable = src.closest('.sumtable'); sumtable.find('input').each(function() { var amt1 = $('input[name="amt1"]').val(); var amt2 = $('input[name="amt2"]').val(); sub = (amt1 - amt2) }); sumtable.find(".netAmt").val(sub.toFixed(2)); } </script> </head> <body> <form class="inward"> <?php include("dbconnection.php"); $sql = "SELECT id,price FROM table1 WHERE id='3' ORDER BY id"; $res = mysql_query($sql) or die(mysql_error()); echo "<table border='1' align='center' cellspacing='0' cellpadding='3' class='sumtable'>"; echo "<tr bgcolor='#CCCCCC' height='30'>"; echo "<td>Price</td>"; echo "<td>Discounted Amt</td>"; echo "<td>Net Amt</td>"; echo "</tr>"; while($row2=mysql_fetch_array($sql2)) { //change row color alternately $i++; $color = ($i%2) ? "#f8f8ff" : "#f0fff0"; echo "<tr bgcolor=" . $color . " onmouseover='ChangeBackgroundColor(this)' onmouseout='RestoreBackgroundColor(this)'> $price = $row2["price"]; if (strlen(trim($price)) == 0) { echo "<td>&nbsp;</td>"; } else { echo "<td valign='top'><input name='amt1' value=" . $price . " size='5'/></td>"; } echo "<td valign='top' ><input name='amt2' size='5'/></td>"; echo "<td valign='top'><input name='netamt' class='netAmt' size='5'/></td>"; echo "</tr>"; } echo "</table>"; echo "<br>"; echo "<tr><td></td></tr>"; echo "<center>"; echo "<input type='submit' name='submit' value='Save' style='cursor:pointer;cursor:hand;'>&nbsp;&nbsp;&nbsp;&nbsp;"; echo "<input type='reset' name='clear' value='Clear' style='cursor:pointer;cursor:hand;'>"; echo "</center>"; ?> </form> </body> </html> </code></pre> <p>Don't Know what's wrong with this any kind of help would be appreciated............</p> <p>In addition to this.....can i get the sum of these subtracted values at the end of loop like Total is: </p>

Guidance

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.
