joomla - How to use Get to update php field -

i found. html - how pre-populate form field known value upon load?

and tried apply learnt from;

<input autocomplete='off' class='logininput' tabindex='3' type="text" name="company" id="company" value="<?php echo $_get["entered"]; ?>" maxlength='50' size="25"> 

to following piece of code ( j-cook component constructing )

<?php // incident $field = $fieldset['jform_incident'] ;  ?> <div class="control-group <?php echo 'field-' . $field->id . $field->responsive; ?>">     <div class="control-label">         <?php echo $field->label; ?>     </div>      <div class="controls">          <?php echo $field->input; ?>

jformfield classes have preset , default options built in (these different, default saves if field left blank) can set in xml (file or string) form. api let change attributes of form or add new attributes. if use api whole code easier write , read. take @ examples in core cms , see many examples. few typical examples below showing add, set , get:

$fieldset->addattribute('description', 'com_categories_item_associations_fieldset_desc');  $field->addattribute('edit', 'true'); $form->setfieldattribute('ordering', 'disabled', 'true'); $fieldname = $field->getattribute('name');
