The FormData class provides a way to easily construct a set of key/value pairs representing form fields and their values.
After using it your script would look like:
<script>
$(document).ready(function(){
var count = 0;
$(document).on('click', '.add', function(){
count++;
var html = '';
html += '<tr>';
html += '<td> </td>';
html += '<input type="hidden" name="item_name[]" class="form-control item_name" />';
html += '<td><select name="item_category[]" class="form-control item_category" data-sub_category_id="'+count+'"><option value="">Select Service Type</option><?php echo fill_select_box($connect, "0"); ?></select></td>';
html += '<td><select name="item_sub_category[]" class="form-control item_sub_category" id="item_sub_category'+count+'"><option value="">Select Service Name</option></select></td>';
html +='<td><input type="text" name="nosessions[]" class="form-control nosessions" /></td>';
html += '<td><button type="button" name="remove" class="btn btn-danger btn-xs remove"><span class="glyphicon glyphicon-minus"></span></button></td>';
$('tbody').append(html);
});
$(document).on('click', '.remove', function(){
$(this).closest('tr').remove();
});
$(document).on('change', '.item_category', function(){
var category_id = $(this).val();
var sub_category_id = $(this).data('sub_category_id');
$.ajax({
url:"fill_sub_category.php",
method:"POST",
data:{category_id:category_id},
success:function(data)
{
var html = '<option value="">Select Sub Category</option>';
html += data;
$('#item_sub_category'+sub_category_id).html(html);
}
})
});
$('#insert_form').on('submit', function(event){
event.preventDefault();
var error = '';
$('.item_category').each(function(){
var count = 1;
if($(this).val() == '')
{
error += '<p>Select Item Category at '+count+' row</p>';
return false;
}
count = count + 1;
});
$('.item_sub_category').each(function(){
var count = 1;
if($(this).val() == '')
{
error += '<p>Select Item Sub category '+count+' Row</p> ';
return false;
}
count = count + 1;
});
$('.nosessions').each(function(){
var count = 1;
if($(this).val() == '')
{
error += '<p>Select no of sessions '+count+' Row</p> ';
return false;
}
count = count + 1;
});
var form_data = new FormData($(this)[0]);
if(error == '')
{
$.ajax({
url:"insert.php",
method:"POST",
data:form_data,
success:function(data)
{
if(data == 'ok')
{
$('#item_table').find('tr:gt(0)').remove();
$('#error').html('<div class="alert alert-success">Item Details Saved</div>');
}
}
});
}
else
{
$('#error').html('<div class="alert alert-danger">'+error+'</div>');
}
});
});
</script>
In addition, you may need to change:
<h5>Package Name:-<input type="text" name="packname" /><input type="hidden" id="packname" name="packname" value="<?php $packname;?>" /></h5>
Into:
<h5>Package Name:-<input type="text" name="packname" value="<?php $packname;?>" disabled="disabled" /></h5>
<input type="hidden" id="packname" name="packname" value="<?php $packname;?>" />
