fopen Question

[Renidrag]

I know, another fopen question - but this one is stumping me

 

server isn't in safe mode, fopen is allowed, directory set to 777, and file to 777 - I can open and read and display the contents of a file but i can not open for "w" writing

 

what else causes the fopen not to open a file with write capabilities?

 

basically i just want to open a file from a custom back end section of my website, i want to display this content in a text box, edit it and have the contents of the file on submit saved to the file

 

so on submit i go to open the file and it will not open for writing.

 

any input is good, thanks in advance

Add the following two lines of code immediately after your first opening <?php tag to show all php generated errors -

 

ini_set ("display_errors", "1");
error_reporting(E_ALL);

 

You would need to post your code to get any help with what it might be doing that is not working.

How do you mean "will not open for writing".  The 'w' will helpfully wipe the file first.  Maybe you want 'a' for append?

[Renidrag]

sorry should have put the code here in the first place

 

[pre]<?php

ini_set ("display_errors", "1");

error_reporting(E_ALL);

$loadcontent = $_GET['a'];

 

if(isset($_POST['btnSave'])){

$savecontent = stripslashes($_POST['content']);

clearstatcache();

ignore_user_abort(true);    ## prevent refresh from aborting file operations and hosing file

$fh = fopen($loadcontent, 'a');    ## use 'r+b' so file can be read and written

if($fh){

if(flock($fh, LOCK_EX))    ## don't do anything unless lock is successful

{

$count = fread($fh, filesize($loadcontent));

rewind($fh);

fwrite($fh, $savecontent);

fflush($fh);

ftruncate($fh, ftell($fh));    ## better than truncating to 0 before writing, per 04-Mar-2003 comment below

flock($fh, LOCK_UN);

}else{

echo "Could not lock current file '$loadcontent'<br />";

echo "<a href='cms_edit.php?a=" . $_GET['a'] . "&link=static'>click here to go back now</a>";

}

fclose($fh);

}else{

echo "<br />Could not open current file '$loadcontent'<br />";

echo "<a href='cms_edit.php?a=" . $_GET['a'] . "&link=static'>click here to go back</a>";

}

ignore_user_abort(false);    ## put things back to normal

}

?>[/pre]

So what is the error? And are you sure that 'a' is set in your URL?

[Renidrag]

the $_GET['a'] is the name of the file to be open for writting to - in the page before it the file does get open with fopen("filename", "r") and it works fine - the content of the page gets diplayed on the page, then i make changes to it and click submit the next page opens the file (from beginning) and over writes the old content with the new content

 

at least that is what it suppose to do

 

but on the follow-up page the file will not open with fopen("filename", "w") or "a" or "r+" or "w+"

 

Warning: fopen(banner_con1.php) [function.fopen]: failed to open stream: Permission denied in /home/xxxxxxxxx/public_html/dev3/xxxxxxxxx_edit.php on line 10

 

says permission denied, but as i mentioned above folder is set to 777 and file is set to 777 and php is not in safe mode

 

and fopen shows as allowed in phpinfo()

Add this:

 

die('loadcontent is: ' . $loadcontent . '.');

 

before this:

 

$fh = fopen($loadcontent, 'a');

 

And make sure that it is set.

[Renidrag]

Add this:

 

die('loadcontent is: ' . $loadcontent . '.');

 

before this:

 

$fh = fopen($loadcontent, 'a');

 

And make sure that it is set.

 

put that in, and yes it comes back with the page name to open

Everything looks right to me then. You should maybe contact your hosting company. It doesn't really make sense that it wouldn't work even with the chmod set to 777. Maybe they have something set on the backend.
