How do you implement php popup warning?

[ngubie]

Hi,

I'm trying to implement a popup warning similar to when a file exists in windows. When you copy a file into the a folder with another file of the same name, a popup appears asking if you are sure you want to overwrite the file.
is there anyway to do that in php? or is there a similar alternative out there?

Thanks

Let me preface this by saying: I know very little.

I do think what you're describing is possible by using mostly javascript. Here is a site that details using alerts with cancel button.

Ya, your looking for JavaScript:



if(confirm('Are you sure you want to do this?')) {
  document.getElementById('myForm').submit();
}

Looks like it won't let me insert the script around this, but you get the jist
