First, I declare that I am using ko3.2.0 version.
Students who use kohana's verification are less aware of it, because each function will give an example. The situation we encountered today is the upload of verification images, and kohana's example looks like this.
Copy the codeThe code is as follows:
$array->rule('file', 'Upload::type', array(array('jpg', 'png', 'gif')));
This is not a problem in itself, but it is always a bit inconvenient in actual applications. Why? Because when it is passed to later processing, it is necessary to not only verify the upload of the image but also verify certain fields of the form form.
Usually we will write this
Copy the codeThe code is as follows:
$post = new Validation($_POST);
$file = new Validation($_FILES);
There is no problem writing this way, and it is OK to write according to the examples when verifying it. But I think it is a bit weird for new2 times, and we also know that $_POST and $_FILES are both arrays. Can you verify it at one time? That's sure, of course, we have to turn them into a large array first. This way it's OK to write.
Copy the codeThe code is as follows:
$post = new Validation(array_merge($_POST,$_FILES));//Classmate who doesn't understand, the array_merge
The key is here, dear. Everyone knows that there is no difference between writing fields in the verification form form and before merging. The key is how to write this image upload (or other uploads used).
Okay, please directly upload the code to the time limit, and you can use it directly. Of course, students who are interested can also try rules.
Copy the codeThe code is as follows:
$post->rule('img','not_empty')
->rule('img','Upload::type',array(':value',array('jpg','png','gif')))
->rule('img','Upload::size',array(':value','1M'));
PS: img is the name of the control input type="file" in the front-end form, and the ID cannot be found in the background.
I will declare again that I use the kohana3.2.0 version. Please modify the writing method of other versions.
