regex help

kmartel

Good afternoon,

I am new the the forums, but I have been advancing my php skills as of late. I have not yet been able to find a regex guide that really explains things in such a way I can understand and apply. So I am looking to the php community to help me with this task.

I have a popup page where a user can browse a file directory, when they click a file name that information is passed to the parent form. What I need to do is retain the last two folders of that path.

For example:
The current method produces "file.txt" in the parent form once clicked from the child page.

I need to pass to the parent form "/path1/path2/file.txt" when "file.txt" is clicked.

I know this is failry simple for some of you, and I thank you for your assistance.

little long but try this...


// use basename to find file
$textTest = "/help/find/the/test/file.php";

$t = explode("/",$textTest);

$c = count($t);
$c = $c - 3;

foreach($t as $key=>$val){

if($key >= $c) echo '/'.$val;

}

Thanks

That works, but I need to pass the data to a variable for mysql database storage... Since that for statement echos' the $val until the count is done, I cant simply $loc = '/'.$val;

I suppose I need a but more help 🙂

Try this...

// use basename to find file 
$textTest = "/help/find/the/test/file.php"; 

$t = explode("/",$textTest); 

$c = count($t); 
$c = $c - 3; 
$loc = '';

foreach($t as $key=>$val){ 

if($key >= $c) $loc .=  '/'.$val; 

} 

echo $loc;

Thanks, it worked like a charm!
