PHP get images filename...not working

[PlagueInfected]

here's what I got

 

<?php 
// starting directory. Dot means current directory
$basedir = "img/portfolio";

// function to count depth of directory 
function getdepth($fn){
  return (($p = strpos($fn, "/")) === false) ? 0 : (1 + getdepth(substr($fn, $p+1)));
}

// function to print a line of html for the indented hyperlink
function printlink($fn){
  $indent = getdepth($fn); // get indent value
  echo "<li class=\"$indent\"><a href=\"http://plagueinfected.com/img/portfolio/$fn\"><img src=\"http://plagueinfected.com/img/portfolio/thumbnails/$fn\">"; //print url
$handle = fopen($fn, "r"); //open web page file
$filestr = fread($handle, 1024); //read top part of html
fclose($handle); //clos web page file
  echo "</a><br>\n"; //finish html
}

// main function that scans the directory tree for web pages 
function listdir($basedir){
    if ($handle = @opendir($basedir)) { 
        while (false !== ($fn = readdir($handle))){ 
            if ($fn != '.' && $fn != '..'){ // ignore these
                $dir = $basedir."/".$fn; 
                if (is_dir($dir)){ 
                    listdir($dir); // recursive call to this function
                } else { //only consider .html etc. files
                    if (preg_match("/[^.\/].+\.(jpg|gif|png)$/",$dir,$fname)) {
                       printlink($fname[0]); //generate the html code
                    }
							} 
            } 
        } 
        closedir($handle); 
    } 
} 
// function call 
listdir($basedir); //this line starts the ball rolling
?>

 

Any ideas?

Try echoing the values you are getting in $fname.. It might not be what you are expecting..

[PlagueInfected]

just tried it,no joy

[Buddski]

What do you mean no joy? did you get any output at all?

[PlagueInfected]

no joy = nothing lol

 

I got no output at all

 

I echoed $fname and even replaced $fn with $fname and I got no output

[Buddski]

What happens if you do this.

function printlink($fn){
echo $fn.'<br/>';
.... the rest of your printlink code

[PlagueInfected]

no output

 

here's how I coded it.

 

<?php 
// starting directory. Dot means current directory
$basedir = "img/portfolio";

// function to count depth of directory 
function getdepth($fn){
  return (($p = strpos($fn, "/")) === false) ? 0 : (1 + getdepth(substr($fn, $p+1)));
}

// function to print a line of html for the indented hyperlink
function printlink($fn){
  $indent = getdepth($fn); // get indent value
  echo $fn . "<br />";
}

// main function that scans the directory tree for web pages 
function listdir($basedir){
    if ($handle = @opendir($basedir)) { 
        while (false !== ($fn = readdir($handle))){ 
            if ($fn != '.' && $fn != '..'){ // ignore these
                $dir = $basedir."/".$fn; 
                if (is_dir($dir)){ 
                    listdir($dir); // recursive call to this function
                } else { //only consider .html etc. files
                    if (preg_match("/[^.\/].+\.(jpg|gif|png)$/",$dir,$fname)) {
                       printlink($fname[0]); //generate the html code
                    }
							} 
            } 
        } 
        closedir($handle); 
    } 
} 
// function call 
listdir($basedir); //this line starts the ball rolling

?>

I tested your code and it works fine on my server..

Have you got error_reporting turned on, you may be getting some errors which are stopping script execution..

[PlagueInfected]

tbh I don't know how to turn it on, lol. Still new to PHP.

 

for the directory path, would I need to include the full URL?

[PlagueInfected]

nvm, found out how to turn it on. It isn't giving me any message or anything.

 

and I can't a single output =/

 

I'm using hostgator as my host? would how they structure the files have something to do with it.

[Buddski]

Ive never used hostgator..

 

You need to remove the error suppression from the opendir call

if ($handle = @opendir($basedir)) { 

should be

if ($handle = opendir($basedir)) { 

[PlagueInfected]

ace got it to work, for some reason now the URL goes to...

 

home/jpmarine/public_html/img/portfolio/velvetacidchrist.jpg

 

anyway to only keep the filename itself?
