PHP: News Script - Advice Wanted

4WebHelp Addict Joined: 07 Jan 2002 Posts: 1060

I've just developed a News Script that I'm happy with, the code is below, but I have one bug, when it generates the articles, if the article filename already exists, it just adds the code underneath the code for the previous article.

What Could I do so it blanks the article out when it does this, and then generates the code from a fresh page - in effect overwriting it, rather than adding it on at the bottom.

I must stress, I only want to do this for the articles themselves, not the summary pages.

The code is below

Code:

<?
include ("template.inc");
include ("config.php");

$summary_template = "t_summary.html";
$article_template = "t_article.html";
$max_summary = 5;

function summary_page ($subject, $date, $summary, $article_id)
{
   global $summary_template;
$t = new Template();
$t->set_file("SummaryPage", $summary_template);
$article_url = "news/".$article_id.".php";
   $date = nl2br($date);
   $summary = nl2br($summary);
   $t->set_var( array(
         "subject" => $subject,
         "date" => $date,
         "summary" => $summary,
         "article_url" => $article_url
         ));
   $t->parse("Summary", "SummaryPage");
   return $t->get_var("Summary");
}

function main_page ($subject, $date, $summary, $article_id, $body)
{
   global $article_template;

$t = new Template();
$t->set_file("ArticlePage", $article_template);
$article_url = "news/".$article_id.".php";
$date = nl2br($date);
$summary = nl2br($summary);
$body = nl2br($body);
$t->set_var( array(
"subject" => $subject,
"date" => $date,
"summary" => $summary,
"body" => $body,
"article_url" => $article_url
));
$t->parse("Article", "ArticlePage");
return $t->get_var("Article");
}

function add_article($filename, $news)
{

   if(file_exists($filename)){
      $fh = fopen($filename, "r");
      $old_news = fread($fh, filesize($filename));
      fclose($fh);
   }

   /* TODO: Multipage articles
      preg_match_all("", $old_news, $matches;

      if( count($matches[0]) >= $max_summary){
         $oldfilename = $filename.($matches[0][0]+1);
      }
   */

   $fh = fopen($filename, "w");
   $news = stripslashes($news);
   fwrite($fh, "\n\n$news $old_news");
   fclose($fh);
}

?>

<?
if(strcmp($subject, "")){
   if(!(strcmp($passwd, $password))){
      add_article("article_summary.html", summary_page($subject, $date, $summary, $article_id));
      add_article("news/$article_id.php", main_page($subject, $date, $summary, $article_id, $body));
      echo "<p> Article has been added! <p>";
   }else{
      echo "<p><b> Password is wrong! </b>";
   }
}
?>

<form action=news.php method=post>
<table border=0>
<tr> <td> (Password): </td><td> <input type=text name=passwd size=30> </td></tr>
<tr> <td> Subject: </td><td> <input type=text name=subject size=30> </td></tr>
<tr> <td> Article ID: </td><td> <input type=text name=article_id value=<? echo date("Y_m_j_is"); ?> size=30> </td></tr>
<tr> <td> Date/Author/etc: </td><td> <textarea name=date rows=2 cols=30 wrap=soft><? echo date("M j, Y\n"); ?>Author: </textarea> </td></tr>
<tr> <td> Summary: </td><td> <textarea name=summary rows=5 cols=30 wrap=soft></textarea> </td></tr>
<tr> <td> Body: </td><td> <textarea name=body rows=15 cols=30></textarea> </td></tr>
</table>
<input type=submit name=submit value=Add>
</form>

Any Ideas?

Thanks!

Hi all,

I've a problem which I hope anyone of you experts out there can render your expertise to help me provide a solution.I'm a newbie....so pls excuse my ignorance.

<tr> <td> Body: </td><td> <textarea name=body rows=15 cols=30></textarea> </td></tr>

Instead of this above <textarea> i used this table.
<table>
<tr><td><input></td><td><input></td><td><input></td><td><input></td><td><input></td></tr>
<tr><td><input></td><td><input></td><td><input></td><td><input></td><td><input></td></tr>
<tr><td><input></td><td><input></td><td><input></td><td><input></td><td><input></td></tr>
<tr><td><input></td><td><input></td><td><input></td><td><input></td><td><input></td></tr>
<tr><td><input></td><td><input></td><td><input></td><td><input></td><td><input></td></tr>
</table>

Every one of those input tags own unique names
...<input name="r1c1">...<input name="r1c2">...
.
.
.
...<input name="r5c5">

? Now question is that still i am unable to add the value inputted by me.
Will some please tell how to do this?
Thanking in advance.
