file_exists

[gnome]

Hi

I am using file_exists to see if a PDF file exists on the server:

if(file_exists($latestNewsletter->url))

{

// link to pdf

}

but this is returning false.

The file definitely exists. If I change to !file_exists, the link is shown and links to the PDF correctly.

Does anyone know why this is happening?

The url dosen't tell the server where the file is. You have to use path.

Edit: I wasn't explicit. When I mean path, I'm talking about the path on the server. You can use $latestNewsletter->path, when $latestNewsletter refers to a file.

Thanks, but if I echo $latestNewsletter->path I get nothing.

[diogo]

What is $latestNewsletter exactly?

edit: sorry, wrong informaton. try this instead: $latestNewsletter->filename

[gnome]

$page->latestNewsletter

latestNewsletter is a file field.

[diogo]

I edited the previous answer, here goes again in case you didn't see

$latestNewsletter->filename

[gnome]

Okay, I got it.

So now I have

if(file_exists($latestNewsletter->filename))

{

?><a href="<?= $latestNewsletter->url; ?>">text</a><?php

}

Thanks for the help

Two more things:

Do you know the cheatsheet? It's an invaluable resourse, all these things are there http://processwire.com/api/cheatsheet/

Concerning your code, you can do the same like this:

if(file_exists($latestNewsletter->filename))
{
  echo "<a href='{$latestNewsletter->url}'>text</a>";
}

All depends on each one's style, and it's perfectly ok, but I think this one is cleaner.

I will check out the cheatsheet.

Your code example is cleaner. I will copy this style from now on.

Thanks again.
