查看/图像/ index.ctp

<?php echo $this->Form->create('Images', array('enctype' => 'multipart/form-data'));?>
<?php echo $this->Form->input('Images.fname', array('between'=>'<br />','type'=>'file'));?>

<?php echo $this->Form->end('Apply');?>

此处文件上传的代码显示为sucussful，文件名在db中插入，但原始图像未上传到 UserImages 文件夹中。为此检查但我没有找到解决方案，请帮助我

Answer 1

$this->data['Images']['fname']['name']仅包含文件名。 $this->data['Images']['fname']['tmp_name']包含文件数据，应与move_uploaded_file();

一起使用

所以你应该改变

move_uploaded_file($this->data['Images']['fname']['name'], WWW_ROOT.DS.'UserImages'.DS.$filename)

到

move_uploaded_file($this->data['Images']['fname']['tmp_name'], WWW_ROOT.DS.'UserImages'.DS.$filename)

您还可以对move_uploaded_file()

进行检查

if(move_uploaded_file($this->data['Images']['fname']['tmp_name'], WWW_ROOT.DS.'UserImages'.DS.$filename)) {
    //continue
} else {
    //show error
}

Answer 2

在cakephp中使用move_uploaded_file（）总是一个不好的做法...因为cakephp总是为图像上传提供一个ImageBehavior ...这会照顾你的图像，文件夹＆amp;图像验证也.... 如果您不了解图像行为，可以从这里学习..... http://cakephplogics.blogspot.in/2014/07/cakephp-image-upload-behavior.html

图片没有上传到我们给出的文件夹中
