keeping file in form to save after correction

[asmith]

I'm trying to get an image from the user in a form.

 

If the form has error like he hasn't type his email, the form is viewed again but his last correct entries is still there, like :

 

<input name=email value=$_POST />

 

how can i keep the image he had uploaded ? what that will be for the "<input type=file" ?

 

 

[s1yman]

if (isset($_FILES['image'])
{
$image = $_FILES[image];
print '<input type="file" value="';
print $image;
print '" name="image" />
}
else
{
print 'put the original form here';
}

 

Is that what you mean?

When the form processing code ends execution, the temporary uploaded file is automatically deleted by php. Your code would need to save the uploaded file somewhere (session, file...). The type="file" value is read only (and if you could put the file name in it, you would be wasting your bandwidth because the same file would be uploaded each time the form gets submitted.)

is there a way i get the address of the file on the users computer,  so that I put his address in that field again?

 

 

@s1yman :  what is $image actually there?

No, you can't. For security reasons, the file field can only be filled in by the browser.

 

Javascript and HTML/php cannot put a value in.

Hold on, theres a chance I'm being an idiot. . . let me just try it

So ... I don't want to ask the user to upload again, How to store it in session?

 

or if i save the file somewhere and user leave my form, How to find it out?

 

I mean I can think of someways to do it, like I store a variable in a session, if the form didn't submit, then checking that variable of the session, so  i delete the file, but is that the standard way?

 

What most people do in these cases?

[s1yman]

how about employing a second form, solely to upload the image?

It can carry the data over from the first form once it is complete. That would save a lot of scripting and bandwith when there is problems.

The best I guess is to store the file in a session.  So that session expire if user do not submit.
