Question

Im与 y二框架表格合作,我采取这样的形式:

<?php echo CHtml::beginForm(  ,  post , array( enctype  =>  multipart/form-data )); ?>
    Image:<?php echo CHtml::activeFileField($model,  image );?>
          <?php echo CHtml::error($model,  image );?>

    Full name: <?php echo CHtml::activeTextField($model,  fullName );?>
               <?php echo CHtml::error($model, fullName ); ?>
   <?php echo CHtml::submitButton( save);?>
<?php echo CHtml::endForm();?>

如果用户投入出现错误,档案现场就变得空洞,用户必须重新展示其形象。是否有办法将档案的实地价值保存在Nyii或php?

简短回答: 无

文档投入依靠用户的当地档案系统,服务器(因此PHP)对此无所知。因此,所提交的表格中,用户必须重选档案。这比任何其他问题都更是一个安全问题。

在这方面,可以采取两种办法改进未爆弹药:

The file will have been successfully uploaded, so you could keep it on the server and use your copy when the form is resubmitted (hard to implement, potentially confusing to the user and generally not recommended)
(better) You could validate the form entry client side with Javascript - or server side via AJAX - before it is submitted. If you do this, you should still validate server-side, but it will help give legitimate users a better user experience, which seems to be what you are bothered about here.
