List PDF files in a directory and select to view

[willyd]

Hi

I have this script running on : http://www.webby-s.com/accueilfr/accueilfrancais.htm
In supports and manuels utilisation.

The script :

<?

function select_menu(){
echo '<select name="myfiles">';
$count = "0";
$style = opendir("/home/wwww3/public_html/accueilfr/Support/manuels/");
while($stylesheet = readdir($style)) {

if ($stylesheet[0] != "." && $stylesheet[0] != ".." ) {
echo "<option value=\"$stylesheet\">$stylesheet</option>";
$count++;
}
}
echo '</select>';
closedir($style);
echo " --- Number of Files: $count";
}

// HTML Form here:
echo '<form method="post" action="">';
echo 'Select a File ';

select_menu();
echo '</form>';

?>

Opens a menu but does not allow me to select the file for opening.
Any help will be highly appreciated.

Thanks

Just a thought, but you have $stylesheet[0] and $stylesheet in the same block of code. Should the $stylesheet be referred to as $stylesheet[0] where you are creating the option tag?

[willyd]

It is possible, however, I am very new to PHP. How would you recommend to do it ?

[Thora_Fan]

Well, seems you have the right idea down, but here is what I would suggest:

function select_menu()
{
	echo "<select name=\"myfiles\">\r";
	$style = opendir("/home/wwww3/public_html/accueilfr/Support/manuels/");
	while(false !== ($stylesheet = readdir($style)))
	{
		// this will check for a ".PDF" extension in the filename
		if(preg_match("/PDF/i", $style))
		{
			echo "<option value=\"$stylesheet\">$stylesheet</option>\r";
			$count++;
		}
	}
	echo "</select>"; 
	closedir($style); 

echo "Number of files -- $count";
}


// HTML Form here: 
echo "<form method=\"POST\" action=\"$_SERVER[PHP_SELF]\">\r";
echo "Select A File: ";
select_menu();
echo "<input type=\"submit\" name=\"submit\" value=\"Submit\">\r";
echo "</form>\r";

The $_SERVER[PHP_SELF] part will make it so that it will post the data to the same page. I haven't tested this, but in theory it should work.

Thanks again,
I get the following error :

function select_menu() { echo "\r"; $style = opendir("/home/wwww3/public_html/accueilfr/Support/manuels/"); while(false !== ($stylesheet = readdir($style))) { // this will check for a ".PDF" extension in the filename if(preg_match("/PDF/i", $style)) { echo "$stylesheet\r"; $count++; } } echo ""; closedir($style); echo "Number of files -- $count"; } // HTML Form here: echo "
\r"; echo "Select A File: "; select_menu(); echo "\r"; echo "
\r";>

Any other ideas ? I am a bit lost here..

[Thora_Fan]

Um, where's the error message?

Hi again,

I changed a bit the script.

You cans ee what it currently does on :

http://www.webby-s.com/accueilfr/Support/manuels.php

Problems :

1. It seems that the pdf selection does not work and that the script would not select any files. I disabled it in the script hereunder but could not understand why it would not work. Any ideas ?
2. Now I have a list of files with the. and .. which I do not want and the submit button would not open the Acrobat Reader. Any ideas ?

Thanks. Here is the modified script :

<?

function select_menu()
{
echo "<select name=\"myfiles\">\r";
$style = opendir("/home/wwww3/public_html/accueilfr/Support/manuels/");
while(false !== ($stylesheet = readdir($style)))
// {
// this will check for a ".PDF" extension in the filename
// if(preg_match("/PDF/i", $style))
{
echo "<option value=\"$stylesheet\">$stylesheet</option>\r";
$count++;
}
// }
echo "</select>";

closedir($style);

echo "Number of files -- $count"; 

}

// HTML Form here:
echo "<form method=\"POST\" action=\"$_SERVER[PHP_SELF]\">\r";
echo "Select A File: ";
select_menu();
echo "<input type=\"submit\" name=\"submit\" value=\"Submit\">\r";
echo "</form>\r";
?>

My bad, try changing

if(preg_match("/PDF/i", $style))

to

if(preg_match("/.PDF/i", $stylesheet))

that should work.

As far as it not actually downloading the PDF's, at the top of the page, try putting something like:

if ($_POST[myfiles])
{
Header("/home/wwww3/public_html/accueilfr/Support/manuels/$_POST[myfiles]";
}

That will, in theory, check to see if something was posted from the form, and if so, send that filename out to the browser (meaning, send the file for download).

Haven't tested it, so that may not work, but give it a shot.

Hi,

The PDF selection works. However, sending it to the browser gives me error like "bad parse at line..."
Maybe I should put the code somewhere else.
Here it is again without the selection. It is on line at the same URL

Also, when clicking on submit, the file name changes in the menu. Is that normal ?

Thanks

[Thora_Fan]

Any time the Header() function is used, it MUST be done prior to any other headers (such as "echo", "include", "require" or "session_start()" for example). Make sure that the block of code that is sending the PDF file to the browser comes prior to anything (including HTML tags).

Hi,

I am getting something else now :

Select A File:
Warning: Cannot modify header information - headers already sent by (output started at /home/wwww3/public_html/accueilfr/Support/manuels.php:28) in /home/wwww3/public_html/accueilfr/Support/manuels.php on line 30
New user manual Ned1.pdf MIBN.pdf MV120E.pdf J125.pdfNumber of files -- 4

Here is the latest code :

<?

function select_menu()
{
echo "<select name=\"myfiles\">\r";
$style = opendir("/home/wwww3/public_html/accueilfr/Support/manuels/");
while(false !== ($stylesheet = readdir($style)))
{
// this will check for a ".PDF" extension in the filename
if(preg_match("/.PDF/i", $stylesheet))

// if(preg_match("/PDF/i", $style))
{
echo "<option value=\"$stylesheet\">$stylesheet</option>\r";
$count++;
}
}
echo "</select>";

closedir($style);

echo "Number of files -- $count"; 

}

// HTML Form here:

if ($POST[myfiles])
echo "<form method=\"POST\" action=\"$SERVER[PHP_SELF]\">\r";
echo "Select A File: ";
//{
Header ("/home/wwww3/public_html/accueilfr/Support/manuels/$_POST[myfiles]");
//}

select_menu();
echo "<input type=\"submit\" name=\"submit\" value=\"Submit\">\r";
echo "</form>\r";

?>

Any other ideas ? Thanks for all the help.

[willyd]

Here is the code that runs now ... Thanks The part that submits has been deactivated due to the error

<?

function select_menu()
{
echo "<select name=\"myfiles\">\r";
$style = opendir("/home/wwww3/public_html/accueilfr/Support/manuels/");
while(false !== ($stylesheet = readdir($style)))
{
// this will check for a ".PDF" extension in the filename
if(preg_match("/.PDF/i", $stylesheet))

// if(preg_match("/PDF/i", $style))
{
echo "<option value=\"$stylesheet\">$stylesheet</option>\r";
$count++;
}
}
echo "</select>";

closedir($style);

echo "Number of files -- $count"; 

}

// HTML Form here:

echo "<form method=\"POST\" action=\"$_SERVER[PHP_SELF]\">\r";
echo "Select A File: ";

//if ($POST[myfiles])
//{
//Header("/home/wwww3/public_html/accueilfr/Support/manuels/$POST[myfiles]";
//}

select_menu();
echo "<input type=\"submit\" name=\"submit\" value=\"Submit\">\r";
echo "</form>\r";
?>
