[RESOLVED] fopen, fwrite, unlink, etc....

[lupus2k5]

Okay, I need some help here. I think the code pretty much explains the concept--it's an online site editor. You create the HTML in a form, click Save!, and it edits the file via the PHP f commands. I don't understand why it won't work!
editor.htm

	    <form name="submit" action="submit.php" method="post">
	    <span class="style4"><br>
		<br>
		Paste HTML here:</span><br>
	    <textarea name="html" rows="7" cols="97"></textarea>
	    <br>
	    <span class="style4">Filename: <? echo $dir; ?><input type="hidden" name="dir" value="<? echo $dir; ?>"><input type="text" value="<? echo $file; ?>" name="filename" <? echo $readonly; ?>> <i>If you cannot edit the text, it is because you cannot rename files. This box is only editable during the creation of new files.</span>
	    </td></tr>
	    </table>

    <br><i>Under Construction:</i><br>
		<input type="submit" value="Save!" style="border:1px solid #008000; font-family:Verdana; font-size:12px" name="submit"><input type="button" value="Cancel" style="border:1px solid #FFFF00; font-family:verdana;font-size:12px" name="cancel" onclick="go_there();"><input type="button" value="Delete" style="border:1px solid #FF0000; font-family:verdana;font-size:12px" name="delete" onclick="go_there();"></td>
      </tr>
  </table>
          <input type="hidden" name="content">
</form>

submit.php

<?
if($action == "edit") {
$fullfile = $dir + $file;
$filehandle = fopen($fullfile,'w') or die("Cannot open file.");
$data = $html;
fwrite($filehandle,$data);
fclose($filehandle);
header("Location: ".$fullfile."");
}
if($action == "delete") {
$fullfile = $dir + $file;
unlink($fullfile);
header("Location: submit.php?action=edit");
}
?>

Any help?

And what problems are you running into? The deletion, the editing? What?

Use the period (.) to concat strings, not + - Try that.

Oh, sorry. My problem is that when I click Save!, I just get a blank page, when it is supposed to be directing me. It doesn't rewrite the file, and I haven't even tried the Delete yet, I just set it up because I was reading a tutorial of how to do it.

I'll try that now...

EDIT: I've come to some progress, mostly because I just realized how dumb I was. In editor.htm, I didn't add the "action" form field, so submit.php didn't know what to do... however, now I get the error "Cannot open file." I'm wondering if the editor to change the files has to be in the same directory as the files being changed? I have the directories set up like this:
/
/thissite/
/thissite/editor/
The "dir" variable is set to "thissite" only if a person is creating a file. If the user is editing a current file, I just use $_SERVER['SCRIPT_NAME'] and the "dir" variable becomes empty. It's not the best strategy, but I am pretty sure it'd work under the circumstances, so I don't know why this doesn't...

Yeah, sounds like a concatentation error. If you can, set the PHP Error Warning level to show all warnings:

error_reporting(E_ALL | E_STRICT);
// OR
ini_set('error_reporting', E_ALL | E_STRICT);

Then see if you get any errors on your page

Thanks, but I just realized I fixed it. The whole problem was that I was using the $filename variable, then I switched to $file, and I couldn't find it. I found that out by trying to display the filename in the error and it was blank.

Gotta go to school now!...
