PHP Problem with loading files into <TEXTAREA></TEXTAREA>

slooksterPSV · Nov 4, 2005

Code:

<?php
	if(!defined('USR'))
		return;
		
	if($_REQUEST['pf1'] != ""){
		$hdl = fopen(HOMEDIR."$usr/".$_REQUEST['pf1'],'w');
		fwrite($hdl, $_REQUEST['pft']);
		fclose($hdl);
		echo "WROTE FILE";
	}
	
	$data = "HELLO WORLD";
	
function gtdr(){

$dir = HOMEDIR.USR;
$dh  = opendir($dir);

    echo "<html><head><title>HTML EDIT</title></head><body>
    	  <form action='desktop.php?a=$eyeapp' method='post'>NAME:<input type='text' name='pf1'>";
echo "<select name='optsel'>";
while (false !== ($filename = readdir($dh))) {
   $files[] = $filename;
   echo "<option value='$filename'>$filename";
}
echo "</select>";
echo "<br>
    	  <input type='submit' name='pfs' value='Save'><input type='submit' name='pfo' value='Open'>
    	  <input type='reset'><br>
    	  <textarea rows='30' cols='86' name='pft'>";
    	  echo $data;
    	  echo "</textarea>
    	  </body></html>";
return "";
}
gtdr();
?>

Ok here is what I'm trying to do. This dynamically updates whatever files are in a directory of your username. HOMEDIR."$usr/" is taken from eyeOS so that I can point to a specific user directory. Here's the problem. I've tried almost everyway I know to load a file into the <textarea> but it won't load using echo $variable; No matter what I've done. the only way, that I've even got remotely close, is by defining the variable right before where it's used but defining it like this.
$data = "INSERT CODE HERE";
echo $data;
That works, but if I define it outside of the function, it won't show up. When I load information from a file into $data, nothing will show in the <textarea> but I can get it to show up in the Window.

Sorry not making too much sense:
I want to load a file into <textarea> using echo $variable that has read data to it, but it won't load the data into <textarea> via echo $variable;
Make sense now? Sorry I know this is kinda hard.

On the first line of your function you need to declare $data as global to get it in scope:

Code:

global $data;

Thanks, it reads one line of the file into the... whatcha ma call it.... Textarea lol. Here's the code I have now:

Code:

<?php
	if(!defined('USR'))
		return;
	global $data;
	global $x;
	$data = "INSERT CODE HERE";
	$x = 0;
	if($_REQUEST['pf1'] != ""){
		$hdl = fopen(HOMEDIR."$usr/".$_REQUEST['pf1'],'w');
		fwrite($hdl, $_REQUEST['pft']);
		fclose($hdl);
		echo "WROTE FILE";
	}
	if(isset($_REQUEST['optsel'])){
		$hdl = fopen(HOMEDIR."$usr/".$_REQUEST['optsel'],'rb');
		global $data;
		 //global $data;
         $data = fgets($hdl, filesize(HOMEDIR."$usr/".$_REQUEST['optsel']));
		fclose($hdl);
	}
	
function gtdr(){

$dir = HOMEDIR.USR;
$dh  = opendir($dir);

    echo "<html><head><title>HTML EDIT</title></head><body>
    	  <form action='desktop.php?a=$eyeapp' method='post' name='oxel'>NAME:<input type='text' name='pf1'>";
echo "<select name='optsel' onchange=''>";
while (false !== ($filename = readdir($dh))) {
   $files[] = $filename;
   echo "<option value='$filename'>$filename";
}
echo "</select>";
echo "<br>
    	  <input type='submit' name='pfs' value='Save'><input type='submit' name='pfo' value='Open'>
    	  <input type='reset'><br>
    	  <textarea rows='30' cols='86' name='pft'>";
    	  global $data;
    	  echo $data;
    	  echo "</textarea>
    	  </body></html>";
return "";
}
gtdr();
?>

EDIT: GOT IT, change fgets to fread and it works perfectly now. Thanks!

Ok since fixing the code I have another problem!
I'm making this an HTML editor, but it's not working. When I put in like <textarea> to be saved and that what's after puts it self as if the code is using it the </textarea> is taking control in the original document. How can I fix this?
In otherwords when I save a file with </textarea> in it, it's making the original file end and puts whatever else is in the file at the end of the page.

MontyZ said:
I'm not sure what you are describing, but, if you are trying to store the phrase "<textarea>" with your text, and don't want this translated as HTML, then you should use the htmlentities() function in PHP to turn characters like < into <

The person from eyeOS helped me fix it. He told me there was an embedded function in eyeOS called textarea(rtrim($text)) that would fix that problem. So I used that and it fixed it =D it replaces it with code values instead of </textarea> characters (it shows the </textarea>, but it just fixes it so that it doesn't conflict).
