Question

function webform_registrationpw_submit($form, &$form_state) {
// first, we need to identify the password field for this registration form
$node = node_load($form_state['values']['details']['nid']);
$nodePassField = "";

  foreach( $node->webform['components'] as $key => $value ) {
    if ( $value['form_key'] =="password"  ) { 
      $nodePassField = $key;
    }
  }

  if ( "" == $form_state['values']['submitted'][$nodePassField] ) { //this is the line giving the error
    $form_state['values']['submitted'][$nodePassField] = newpw(8);  // set new password
  }
}

大家好，以上是给我一个“Undefined offset：4”错误的代码。我已经尝试使用isset（）和其他一些东西，我继续得到错误。你能救我吗？我还很新，还在学习。

感谢。

原来有一些奇怪的错误，“if”正在寻找一个空字段。所以删除了if并将代码修改为：

function webform_registrationpw_submit($form, &$form_state) {
// first, we need to identify the password field for this registration form
$node = node_load($form_state['values']['details']['nid']);
$nodePassField = "";

  foreach( $node->webform['components'] as $key => $value ) {
    if ( $value['form_key'] =="password"  ) { 
      $nodePassField = $key;
    }
  }
  $form_state['values']['submitted'][$nodePassField] = newpw(8);  // set new password
}

Viola，效果很好！

未定义的偏移：4尝试了很多补救措施
