Answer 1

The input values not immediately affect on your input but You will get your new value while you submitting your form.
So submit your form and then print the values of the Request. You will find the new value of total_fees into the request parameters.

HTML CODE
<form name="jqueryForm" method="post" id="jqueryForm" enctype="multipart/form-data" onSubmit="return validme();">
<table border="0" cellspacing="15" cellpadding="0" width="100%" >
<tr>
<td width="22%">Course Fees</td>
<td width="38%">
<div id=total_fees>
<input type="text" class="input_text" name="total_fees" id="toal_fees" onblur="show_record(this.value,1)" value="<?php if($_POST['total_fees']) echo $_POST['total_fees']; else echo $row['total_fees'];?>" />
</div>
</td>
<td width="40%"></td>
</tr>
<tr>
<td width="22%">Discount in <input type="radio" name='discount_type' value="<?php if($_POST['discount_type']) echo $_POST['discount_type']; else echo percent; ?>" checked="checked" onChange="show_record()" />% or <input type="radio" name='discount_type' value="<?php if($_POST['discount_type']) echo $_POST['discount_type']; else echo cash; ?>" onChange="show_record()" />Cash</td>
<td width="38%"><input type="text" class="input_text" name="concession" id="concession" value="<?php if($_POST['concession']) echo $_POST['concession']; else if($row_record['discount'] !=0) echo $row_record['discount']; else echo 0; ?>" onBlur="show_record()"/>
</td>
<td width="40%"></td>
</tr>
</table>
<input type="submit" value="Save Record" name="save_changes" />
</form>
PHP CODE FOR SAVE IN DB
if(isset($_POST['save_changes']))
{
$total_fees=($_POST['total_fees']) ? $_POST['total_fees'] : "0";
$data_record['total_fees']=$total_fees;
$courses_id=$db->query_insert("enroll", $data_record);
}
