if files exist show link ?

if file exist show link to file

I have a simple form with an option to upload a small file, the file names are renamed to id numbers 01-999999 etc...

Currently I'm showing a link to the file, but not all users will have uploaded a file, so how would I go about not showing a link if the file doesn't exist (vise versa) ?

PS: I don't want to involve database query's

 

I think you can use the function file_exists ...

http://www.php.net/file_exists

... to do what you are looking for.

Hi and thanks, yeah I'm using that

<?php
$filename = '/path/to/foo.txt';

if (file_exists($filename)) {
    echo "The file $filename exists";
} else {
    echo "The file $filename does not exist";
}
?>

Code (markup):

But any ideas on how I would implement that to show a link to the file on a template page and of course not a show a link if the file doesn't exist ?

 

Do you mean hyper link?

 

yes a <a href=" link to the file, but only if it exist

 

Try this

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

Code (php):

Are you using relative path or absolute path to know the existence of the file? e.g.
/path/to/foo.txt
or
path/to/foo.txt

 

OK I'm getting there, but I'm having a problem with writing the following into php

lets assume I'm using your example with the printed result been $play

if (file_exists($filename)) {
    echo "<a href='$filename'>$play</a>";
}

Code (php):

This is my problem, its not right and I cant figure out whats wrong with it.

$play = "- <a href="javascript:sendtoflash2('previewswf','../adverts/{$link.ID}');"><u>Listen</u></a> | <a href="javascript:sendtoflash2('previewswf','../adverts/nosound.mp3');"><u>Audio Off</u></a>";

Code (php):

 

Try

$play = "- <a href=\"javascript:sendtoflash2('previewswf','../adverts/{$link.ID}');\"><u>Listen</u></a> | <a href=\"javascript:sendtoflash2('previewswf','../adverts/nosound.mp3');\"><u>Audio Off</u></a>";

PHP:

Escape " with \"

 

$play = "- <a href=\"javascript:sendtoflash2('previewswf','../adverts/{$link.ID}');\"><u>Listen</u></a> | <a href=\"javascript:sendtoflash2('previewswf','../adverts/nosound.mp3');\"><u>Audio Off</u></a>";

Code (php):

 

Hmm page wont load, by accounts the \ was what I thought was wrong but nope just wont load, theres some other kind of error stopping the php page from loading and its that line $play =

 

Does the page working fine without line $play=?

 

yes

and the code itself is fine it currently working on the .tpl page but as above I'm trying to replace it with {$play} so the link only shows if there is indeed a file.

 

Are you using some template engine? Try without quotes around href value

$play = "- <a href=javascript:sendtoflash2('previewswf','../adverts/{$link.ID}');><u>Listen</u></a> | <a href=javascript:sendtoflash2('previewswf','../adverts/nosound.mp3');><u>Audio Off</u></a>";

Code (php):

 

nope... I'm lost

 

Did you try the code i provided in the last post?

 

Yes.. page wont load, strange I guess it just doesn't like javascript or something

 

Can you send me the complete page source code so that I can look into the issue?

 

Theres nothing really to send, I just need to get that line working so php can read it

 

OMG I'm a noob, just spotted what was wrong, i was using a template variable in the php file {$link.ID}

Ok thats that solved but I think i still have a problem...

 

What is the problem?
