fwrite

Anon

I am new to php. Here is what I would like to do. I have an array of site page ie main.txt. I currently can open the text file to view the content of the file. I am not sure how fwrite works. Any help would be greatly appreciated. Here is the code I have so far.
<?
include ("config_theme.php");
include ("mysite.php");
echo"<table width =400 border =0><tr><td>";
echo"<form name=admin action=$PHP_SELF method=post enctype=multipart/form-data> ";
echo"<input type=hidden name=pages value=main.txt; > ";
echo "<select onChange=publish(this.form) name=pages>";
for ($i = 0; $i < count ($site_titles); $i++)
echo " <option value= $site_pages[$i].txt>$site_titles[$i]</option>";
echo " <option value= main.txt selected>choose a page</option>";
echo "</select>";
echo"</td></tr><tr><td>";
$filename=$pages;
if ($filename == ""){ echo "<textarea name=pagetext cols=50 rows=25 value=Please select a page ></textarea>";}
else {
$fp = fopen($filename, "r");
$content .= fread( $fp, filesize( $filename ));
fclose($fp);
echo "<textarea name=pagetext cols=50 rows=25 value=$content ></textarea>";
echo"</td></tr></table>";
echo"</form>";}
?>

Well, it's hard to conclude from your code what it is you're trying to do. You now have a variable with the content of a whole file. With fwrite you can write other things back to a file (eg input from a user), and either append it or overwrite the current output. This is probably not what you want to do; please state clearly what it is you're trying to do.

What I am trying to do is I have txt files for the content of each page on my site. I am trying to build a admin page where I can pull the page content I want to change from the textfile. I am able to display the content with my code I am using now.My next step is change the content of that file and write it back to the text file so the site content will reflect the changes. On mysite.php I have an array of all the text files. I have a dropdown list on the code I posted. So what I would do is select the page ie Main. Then it displays the txt file for main which is the content for main.phtml. As stated earlier I would like to be able to change the content from a admin page. I just am not sure how to write the new content back to the txt file using fwrite. I hope this make things a litle more clear.

Ah yes it does. You're basically building an editor with html forms. Well, what you do is you read the file into a string, and put this string inside a <textarea>. You can now edit the text; ofcouse make a submit button so that you can save changes. In the page you submit to (let's save save.php), you open the file again, but this time not with 'r', but with 'w'. You can now do fwrite($fp, $string) where $string is the value that you got back from your previous form (with the textarea). Be sure to handle things like escaping quotes when you're passing complete texts from a form. Also be sure to use post and not get, as get has a limit of 1024 characters.

I have tried to figure out a way to this but I can't get it working let me include all my code here.
mysite.php contains this array

//This is an array of all pages w/out
// the .php3 extension. You should
// place these in the array in the
// order you'd like the menu to be
// generated.
$site_pages = array ("main",
"about",
"method",
"services", "hosting" "contact", "port", "jobs"
);
// This is an array of page titles.
// e.g. ALT text. You should place
// these in the array corresponding
// to the order of the $site_pages
// array.
$site_titles = array ("home",
"about us",
"methodology",
"services", "web hosting",
"contact us",
"portfolio",
"jobs"
);
$page = getenv ("SCRIPT_NAME");
$page .= basename ($page);
This is where I am getting my pages from for my array in myadmin.php Next let me show you all my code for myadmin.php
<script language=javascript>
<!-- hide from older browsers

  function publish() { 
      document.admin.submit(); 
  }

// unhide -->

</script>
<?
include ("config_theme.php");
include ("mysite.php");

echo"<table width =400 border =0><tr><td>";
echo"<form name=admin action=$PHP_SELF method=post enctype=multipart/form-data> ";
echo "<select name=pages onChange=publish(this.form)>";
for ($i = 0; $i < count ($site_titles); $i++)
echo " <option value= $site_pages[$i].txt>$site_titles[$i]</option>";
echo " <option value= main.txt selected>choose a page</option>";
echo "</select>";
echo"</td></tr><tr><td>";
$filename=$pages;
if ($filename == ""){ echo "";}
else {
$fp = fopen($filename, "r");
$content .= fread( $fp, filesize( $filename ));
fclose($fp);
echo "<textarea type =hidden name=pagetext cols=50 rows=25 value=$content ></textarea>";
echo"</td></tr></table>";
echo"</form>";}
echo"<input type=submit name=Submit value=Submit>";

Now let me explain the Big Picture. What I envision is we have a admin page to update all the content on the site. I am using Fast Templates and have txt files for the content of each page. So main.phtml has a text file main.txt for the content. So far I have been able to add a dropdown menu to myadmin.php. When I select a page it open the text file. ie I select home it opens main.txt because the value for home is main.txt. Next Since I have gotten this far I would like to update the text file from one page myadmin.php I have spent hours trying to figure this out and just can't get it to work right. So if anyone could please help. I know I need to use fwrite to accomplish this. I am a newbie to php and have only been using for about 2 weeks. I hope I have covered all basis. I just need some help with the fwrite part of the code. Thanks in advanced!

Actually I solved this issue for a lot of customers, and finished a small "tutorial" for people that want to do the same, you can read it up here:

http://www.onlinetools.org/articles/editablepages.php

the writing part is explained further down...

Make sure to use "" around your form values though, it is not at all readable and standard compliant, and once you use spaces, it'll be f*§"ed up...

cheers,
