[development] Values not retained

Mon Jan 10 06:44:59 UTC 2011

This part of the code is not retaining the previous value.....

$form['characteristics']=array(
'#type' => 'textfield',
'#size'=> 20,
//'#title' => t('rows @n', array('@n' => ($delta + 1))),
'#prefix'=>'<table class="table2"><tr><td class="table2row">',
'#suffix'=>'</td>',
'#default_value' => !empty($form_state['values']['characteristics']) ?
$form_state['values']['characteristics'] : '',
'#parents' => array('rows', $delta, 'chars'),
);

$form['description']=array(
'#type' => 'textfield',
'#size'=> 20,
//'#title' => t('rows @n', array('@n' => ($delta + 1))),
'#prefix'=>'<td class="table2row">',
'#suffix'=>'</td>',
'#default_value' => !empty($form_state['values']['description']) ?
$form_state['values']['description'] : '',
'#parents' => array('rows', $delta, 'descr'),
);
$form['minimum']=array(
'#type' => 'textfield',
'#size'=> 20,
// '#title' => t('rows @n', array('@n' => ($delta + 1))),
'#prefix'=>'<td class="table2row">',
'#suffix'=>'</td>',
'#default_value' => !empty($form_state['values']['minimum']) ?
$form_state['values']['minimum'] : '',
'#parents' => array('rows', $delta, 'min'),
);
$form['maximum']=array(
'#type' => 'textfield',
'#size'=> 20,
//'#title' => t('rows @n', array('@n' => ($delta + 1))),
'#prefix'=>'<td class="table2row">',
'#suffix'=>'</td></tr></table>',
'#default_value' => !empty($form_state['values']['maximum']) ?
$form_state['values']['maximum'] : '',
'#parents' => array('rows', $delta, 'max'),
);
