PHP file upload form cannot submit a POST variable?

问题

I have a PHP file upload form with method="post" enctype="multipart/form-data"

I am trying to do a <input type = "hidden" name = 'something' value = "something"/> along with the input for file upload, but I am not able to get the value of 'something' in the upload handling script like $_POST['something']

Is it not possible to use POST variables along with a file upload? Any other alternative on how I can pass information to the upload handling script?

回答1:

First, having some consistency with which quotes you use would be a good first step.

Second, you have got the enctype correct, so what may be an issue is you've exceeded the servers file upload size or post size settings. Try upload a smaller file and see if that works.

回答2:

You can use other inputs along with the file upload fields.

Ensure that:

• All fields are inside form tags
• Youdidn't misspell field names and array indexes
• You are using "double qutes" everywhere in your HTML (just in case)

To debug, try putting this code at the top of your script to see what is being passed:

echo '<xmp>';
print_r($_POST);
echo '</xmp>';

I know this question is old, but I'll post anyway... maybe I can help someone.

In my case the problem was the 'post_max_size' in php.ini.

Cheers.
