simple file writing problem

[heepofajeep]

(see bottom for quick question)

Hi, I am trying to make a thumbnail program that will cycle through each dir in a given dir (eg all folders in my pic folder), and create a gallery php page for each dir. (ie for "DOG" pics folder, gallery_DOGS.php is created)

Now, my problem lies with the actual thumnail writing process. I can't seem to get it to make a thumbnail file in a SPECIFIC folder--it will only make one in the current home directory🙁.

SOoo, how do I open a dir, and then create an image file (or any file for that matter) in that dir?

what code are you using?

Here is the program that will create thumbnails and a php file in whatever directory it is in. I have the one that I was working on, also, to accomplish the above, but it is getting pretty messy so I am just starting over (using the file that you see).

Thanks for any help!!!

$thumbsfolder= ".";
$pics=directory($imagefolder,"jpg,JPG,JPEG,jpeg,png,PNG");

print "$file";
$phpname="gallery.php";
$pics=ditchtn($pics,"tn");
if ($pics[0]!="")
{
foreach ($pics as $p)
{
createthumb($p,"tn".$p,150,150);
}

phpcreator($pics,"tn_",$phpname,$imagefolder);
}

}
return $tmparr;

i think what you want is scandir();
Look at it here: http://us3.php.net/manual/en/function.scandir.php
Then you can just use come kind of foreach(); function....

Hmmm, the problem with that, is that it is similar to: $dh = opendir($dir);
while (false !== ($filename = readdir($dh))){}, which is what I have been trying to use. The problem that I am having is I see no way to write to a specific dir, only read what is in a specific dir. Granted, I could use fopen, and fwrite, but that only deals with a file.

Here is the code that I was working on to get the program to do what I wanted.

Sorry it is so messy!

<?php
$imagetype="jpg,JPG,jpeg,JPEG,PNG,png";
$currentdir = opendir(".");
while (($file= readdir($currentdir))!==false)
{
$filetype = filetype($file);
if ($filetype == "dir" && $file != ".." )
{
print " <br>filetype:$filetype, ";
print "file:$file<br><br>";
$imagefolder = $file;
$thumbsfolder= $file;
$imagetype = "jpg,JPG,jpeg,JPEG,png,PNG";
if (imagefinder($imagetype,$imagefolder)>=5)
{
$pics=directory($imagefolder,$imagetype);
$phpname="g$file.php";
$pics=ditchtn($pics,"tn");
if ($pics[0]!="")
{
foreach ($pics as $p)
{ createthumb($p,"tn_".$p,150,150,$thumbsfolder); }

			phpcreator($pics,"tn_",$phpname,$imagefolder);

			}
		}	
	}		
}

function imagefinder ($filetype,$imagefolder)
{
$currentdir=opendir($imagefolder);
$files=array();
$filename=array();
$filenumber = 0;
$filetp = explode (",",$filetype);

while (($file=readdir($currentdir))!==false)
{
	$filename = explode(".",$file);
	if (isset($filename[1]))
	{
		foreach($filetp as $type)
		{
			if ($filename[1] == $type)
			{	
				++$filenumber;
			}

		}
	}

I didn't read your code (source always seems to go ugly when it's not properly formatted). So maybe you are doing this --- but if I'm writing a file into a subdirectory for me it's just a matter of fopen('subdirectory/filename.ext', 'w');

[batman]

I was thinking more along the line:

 foreach($dir as $directory);
{
$d = fopen("$directory", "w");
        fwrite($d, "your info\n");
        fclose($d);
}

I am using the above to create the php file containing links to the pictures, but my problem really lies in creating a thumbnail--
The problem I am having is that $src_img only seems to work if it is in the home directory, and imagecreatexxx seems to only create into the home directory. No problem on not reading it by the way! Here is the section that I seem to be having problems with. Thanks a million!

function createthumb($name,$filename,$new_w,$new_h,)
{
$system=explode(".",$name);
if (preg_match("/|JPG|JPEG|jpg|jpeg/",$system[1]))
{
$src_img=imagecreatefromjpeg($name);
}
if (preg_match("/png|PNG/",$system[1]))
{
$src_img=imagecreatefrompng($name);
}

$old_x=imageSX($src_img);
$old_y=imageSY($src_img);

$thumb_w=$new_w;
$thumb_h=$new_h;
}
$dst_img=ImageCreateTrueColor($thumb_w,$thumb_h);
imagecopyresampled($dst_img,$src_img,0,0,0,0,$thumb_w,$thumb_h,$old_x,$old_y);
if (preg_match("/png/",$system[1]))
{
imagepng($dst_img,$filename);
} else {
imagejpeg($dst_img,$filename);
}
imagedestroy($dst_img);
imagedestroy($src_img);
}

so the above code i gave you works for seeing all the directories? It almost sounds as if its doing its job by placing the script in all dirs but it sounds like it is just sitting in the directory not executing the script.

The problem is that if $directory is a directory, then you can't write stuff in it - a directory is a fixed-size thingy maintained by the filesystem that just points to a list of files. If you want to "write something in a directory" you'll need an ordinary file in the directory. Or copy an entire pre-existing file there.
