Echoing variable and more - Help a php newb? =D

Daniel_Exe

Hello everyone,
My name's Daniel and I'm fairly new to PHP. At the moment, I'm trying to make my site more automatic when it comes to adding content and such by using PHP when needed. I'm now trying to make the addition of graphics to my site to be fairly automatic by using the following code:

<?PHP include 'free/signatures/pagination.php'; ?>

<table border="0" width="400" cellspacing="1">
<?PHP
  $list_ignore = array ('.','..','images','Thumbs.db','index.php','index2.php','index3.php','pagination.php','error_log');
  $direct = getcwd();
  $part = explode('/', $direct);
  $foldernumber = $part[6];
  $handle=opendir("free/signatures/$foldernumber/");
  $dirs=array();
  $files=array();
  $i = 0;

  while (false !== ($file = readdir($handle))) {
   if (!in_array($file,$list_ignore)) {
     if(!eregi("([.]bak)",$file)) {
       if(is_dir($file)) {
         $dirs[]=$file;
       } else {
         $files[]=$file;
       }
       $i++;
     }
   }
  }
  closedir($handle);
  $tab=array_merge($dirs,$files);
  rsort($tab); // change order
  if ($i) {
   foreach ($tab as $rep) {
     if(eregi("([.]gif)|([.]jpg)|([.]jpeg)|([.]png)|([.]bmp)", $rep)) {
       $ext="images";
     } elseif($rep[folder]==true) {
       $ext="folder";
     } else {
       $ext="text";
     }
     echo ('<tr>
				<td><img src="free/signatures/"$foldernumber"/'.$rep.'" border="0" alt="image" /></td>
			</tr>');
   }
  } else {
   echo "No files";
  }
?>
</table>
<br /><br />

For some reason, with the code posted above, <img src="free/signatures/"$foldernumber"/'.$rep.'" border="0" alt="image" /> will not echo $foldernumber and $rep. Instead, it simply displays something like http://www.mysite.com/free/signatures/. Before I had added

  $direct = getcwd();
  $part = explode('/', $direct);
  $foldernumber = $part[6];
  $handle=opendir("free/signatures/$foldernumber/");

and replaced all instances of 1 with "$foldernumber", the code worked perfectly. I'm very confused why the code won't simply echo the variable.. I'm fairly new to PHP and understand some basics although why this isn't working is completely beyond me. I simply cannot find what the problem is.. Any help would be greatly appreciated.
Thanks,
Daniel

Your echo should be more like this:

echo '<tr> 
        <td><img src="free/signatures/' . $foldernumber . '/' . $rep . '" border="0" alt="image" /></td> 
      </tr>';

Hm..well, now the $rep is being echoed, but $foldernumber seems to be blank for some reason. The url of the images are always free/signatures//7 (7 being $rep, so it changes for each image in the folder). I did specify that $foldernumber equals to $part[6], so maybe I could just reffer to that array instead of containing it in a variable? I still don't understand what could be causing this..

Your issue appears to be that PHP is not aware that you want to echo $foldernumber, because you have it embebbed in a string and PHP just sees it as some text. Change these two lines of code to read as below and you should be good to go:

  $handle=opendir("free/signatures/".$foldernumber."/");

echo "<tr><td><img src=\"free/signatures/".$foldernumber."/".$rep."\" border=\"0\" alt=\"image\" /></td></tr>

I tried applying your changes HeyRay2, yet it still doesn't seem to work. Here's my code at the moment:

<?PHP include 'free/signatures/pagination.php'; ?>

<table border="0" width="400" cellspacing="1">
<?PHP
  $list_ignore = array ('.','..','images','Thumbs.db','index.php','index2.php','index3.php','pagination.php','error_log');
  $direct = getcwd();
  $part = explode('/', $direct);
  $foldernumber = $part[6];
  $handle=opendir("free/signatures/".$foldernumber."/"); 
  $dirs=array();
  $files=array();
  $i = 0;

  while (false !== ($file = readdir($handle))) {
   if (!in_array($file,$list_ignore)) {
     if(!eregi("([.]bak)",$file)) {
       if(is_dir($file)) {
         $dirs[]=$file;
       } else {
         $files[]=$file;
       }
       $i++;
     }
   }
  }
  closedir($handle);
  $tab=array_merge($dirs,$files);
  rsort($tab); // change order
  if ($i) {
   foreach ($tab as $rep) {
     if(eregi("([.]gif)|([.]jpg)|([.]jpeg)|([.]png)|([.]bmp)", $rep)) {
       $ext="images";
     } elseif($rep[folder]==true) {
       $ext="folder";
     } else {
       $ext="text";
     }
		echo "<tr><td><img src=\"free/signatures/".$foldernumber."/".$rep."\" border=\"0\" alt=\"image\" /></td></tr>";
   }
  } else {
   echo "No files";
  }
?>
</table>
<br /><br />

Here's the test page: http://www.gamexe.net/layout.php?id=f=6=10. It still isn't echoing $foldernumber and for some reason, it won't echo the extension of the files anymore. =/
Thanks for the help so far though,
Daniel

HeyRay2

Your problem must lie in...

$direct = getcwd(); 
$part = explode('/', $direct); 
$foldernumber = $part[6];

It may not be pulling the correct information. Add the lines:

$direct = getcwd(); 
$part = explode('/', $direct); 
$foldernumber = $part[6];

// Add this
foreach($part as $key=>$value){
     echo $value."<br />";
}

and post the results here

Ughh...Because the file is being included by layout.php, getcwd() is simply grabing the path in which that file is located in and not the file containing the php code. So, it keeps using public_html as $foldernumber, and thus it doesn't put anything seing as that's the root directory. Now I need to figuire out another way to fix this, or possibly even change the way my layout includes files... Any chance someone might have a better idea of how to achieve what I would like to do?
Much appreciated,
Daniel
