<?php defined('_jexec') or die;  jhtml::_('behavior.keepalive'); jhtml::_('behavior.tooltip'); jhtml::_('behavior.formvalidation'); ?>  <div class="item" <?php echo $this->pageclass_sfx?>"> <?php if ($this->params->get('show_page_heading')) : ?>     <h1><?php echo $this->escape($this->params->get('page_heading')); ?></h1> <?php endif; ?>  <form id="add-item" action="<?php echo jroute::_('index.php?option=com_stationery&task=item.save'); ?>" method="post" class="form-validate" enctype="multipart/form-data"> <?php foreach ($this->form->getfieldsets() $fieldset): // iterate through form fieldsets , display each one.?>     <?php $fields = $this->form->getfieldset($fieldset->name);?>     <?php if (count($fields)):?>         <fieldset>         <?php if (isset($fieldset->label)):// if fieldset has label set, display legend.         ?>             <legend><?php echo jtext::_($fieldset->label);?></legend>         <?php endif;?>             <dl>         <?php foreach($fields $field):// iterate through fields in set , display them.?>             <?php if ($field->hidden):// if field hidden, display input.?>                 <?php echo $field->input;?>             <?php else:?>                 <dt>                     <?php echo $field->label; // show label registor ?>                     <?php if (!$field->required && $field->type!='spacer'): ?>                      <?php endif; ?>                 </dt>                 <dd><?php echo ($field->type!='spacer') ? $field->input : "&#160;"; ?></dd>             <?php endif;?>         <?php endforeach;?>             </dl>         </fieldset>     <?php endif;?> <?php endforeach;?>         <div>             <button name="save" type="submit" class="btn btn-success" class="validate"><?php echo jtext::_('save');?></button>             <?php echo jtext::_('or');?>             <a class="btn btn-danger" href="<?php echo jroute::_('/stationery/index.php/add-items');?>" title="<?php echo jtext::_('jcancel');?>"><?php echo jtext::_('jcancel');?></a>             <input type="hidden" name="option" value="com_stationery" />             <input type="hidden" name="task" value="item.save" />             <?php echo jhtml::_('form.token');?>          </div>     </form> <script>

this loop field.xml show each field. want value in inputbox. can javascript variable can't use save in table. want php variable ($....). how can it? please me. thank you

in joomla 2.5+ use jrequest, since it's deprecated should:

jfactory::getapplication()->input->get...

however looking @ code there may simpler approach bind input table model
