[SOLVED] if statement

[richard_PHP]

back again so soon!!!

 

i was just wondering if there was a way to display a message saying 'no files to show' in an if statement when there are no files in a directory.

 

code:

      <form action="remove.php" method="post" name="list">
         <?
            //define the path as relative
            $path = "uploads/";
            //using the opendir function
            $dir_handle = @opendir($path) or die("Unable to open $path");
            //running the while loop
            while ($file = readdir($dir_handle)) {
               if($file!="." && $file!="..")
               echo "<input name='files' type='radio' value='$file' /><a href='uploads/$file' target='_blank'>$file</a><br />";
            }
            //closing the directory
            closedir($dir_handle);
         ?>
         <p><input name="submit" type="submit" value="Delete File" /></p>
      </form>

 

so if there are no files to list in the directory then display the message: NO FILES FOUND

Use a counter if counter is greater than two, you have files else you have no files because you have ".." and "." .

Not sure but maybe something like this?

 

EDIT: I change the code and added a else to you if statment, not sure if it would work or not

            <form action="remove.php" method="post" name="list">
         <?
            //define the path as relative
            $path = "uploads/";
            //using the opendir function
            $dir_handle = @opendir($path) or die("Unable to open $path");
            //running the while loop
            if (!$dir_handle) {

                while ($file = readdir($dir_handle)) {
                   if($file!="." && $file!="..")
                       echo "<input name='files' type='radio' value='$file' /><a href='uploads/$file' target='_blank'>$file</a><br />";
                   }else{
				   echo "No files message";
			   }
		}
                   //closing the directory
                   closedir($dir_handle);
         ?>
         <p><input name="submit" type="submit" value="Delete File" /></p>
      </form>

Counter.

[richard_PHP]

<?
            $counter = $file < 1;
		//define the path as relative
            $path = "uploads/";
            //using the opendir function
            $dir_handle = @opendir($path) or die("Unable to open $path");
            //running the while loop
            while ($file = readdir($dir_handle)) {
			if($file!="." && $file!="..")
			echo "<input name='files' type='radio' value='$file' /><a href='uploads/$file' target='_blank'>$file</a><br />";
			if ($counter){
			echo "Nothing to see.";
		   }
		  }
            //closing the directory
            closedir($dir_handle);
         ?>

 

Just echos NOTHING TO SEE on the left of each file if there are files there already. 

 

EDIT: and when there are no files, its put twice.

[WolfRage]

<?
$counter = 0;
//define the path as relative
$path = "uploads/";
//using the opendir function
$dir_handle = @opendir($path) or die("Unable to open $path");
//running the while loop
while ($file = readdir($dir_handle)) {
             $counter++;
if($file!="." && $file!="..")
echo "<input name='files' type='radio' value='$file' /><a href='uploads/$file' target='_blank'>$file</a><br />";
if ($counter===2){
         echo "Nothing to see.";
		}
		  }
            //closing the directory
            closedir($dir_handle);
         ?>

[richard_PHP]

that displays NOTHING TO SEE just the once (  ), however even if there is a file it displays the message next to the first file. (  )

[Mark Baker]

$counter = 0;
//define the path as relative
$path = "uploads/";
//using the opendir function
$dir_handle = @opendir($path) or die("Unable to open $path");
//running the while loop
while ($file = readdir($dir_handle)) {
    $counter++;
    if($file!="." && $file!="..")
        echo "<input name='files' type='radio' value='$file' /><a href='uploads/$file' target='_blank'>$file</a><br />";
    }
    //closing the directory
    closedir($dir_handle);
}
if ($counter == 2){
    echo "Nothing to see.";
}

Hi

 

Or this, which saves playing with the counter.

 

      <form action="remove.php" method="post" name="list">
         <?
            //define the path as relative
            $path = "uploads/";
            //using the opendir function
            $dir_handle = @opendir($path) or die("Unable to open $path");
            //running the while loop
		$OutStr = "";
            while ($file = readdir($dir_handle)) {
               if($file!="." && $file!="..")
               $OutStr .= "<input name='files' type='radio' value='$file' /><a href='uploads/$file' target='_blank'>$file</a><br />";
            }
            //closing the directory
            closedir($dir_handle);
		echo (($OutStr) ? $OutStr : "Nothing to see.");
         ?>
         <p><input name="submit" type="submit" value="Delete File" /></p>
      </form>

 

All the best
