inserting Php code

chwebdesigns · February 25, 2008

Hi,

I have this code which inserts, when a form is filled in, into an rss feed. THe only problem is that it inserts it after the closing tags (</channel></rss>) Is there a way of making the php code insert it before these tags?

Thanks

From Cal

I CANT SEEM TO PUT MY PASTE MY CODE IN (I forget the first time :-[ ) ANYBODY GOT ANY IDEAS ON HOW TO POST CODE?

Copy, paste

chwebdesigns · February 25, 2008

i have tried that! but it comes up with a meesage screen saying "Error 403 website declined to show you this page) ??? ???

lol, try this thread on posting:

http://www.phpfreaks.com/forums/index.php/topic,96050.0.html

-----

without the code...

i believe you could use:

str_replace("</channel></rss>",$feed."</channel></rss>",$rssfeed);

there may be other more efficient ways of doing this, it basically replaces the end tags with the content+end tags.

hope this helps,

 $fe = fopen ('feedy.xml','a');
        if(!$fe) {
            echo "<h1 align=\"center\">Error opening RSS Feed! Please try again. If the error continues please contact the webmaster</h1>";
            exit;
        }
        $item = "<item><title>" . $HTTP_POST_VARS['title'];
	$item .= "</title><description>" . $HTTP_POST_VARS['news'] ;
	$item .= "</description><link>" . $HTTP_POST_VARS['anchor'];
        $item .= "</link><pubDate>" . date("D, d M Y H:i:s ") . "GMT</pubDate></item>" ;
        $item = str_replace("\r\n","<BR>",$item);
        $item .= "\r\n";
        fwrite ($fe, $item);
        if(!fclose ($fe)) {
            echo "Error closing file! Please try again. If the error continues please contact the webmaster";
            exit;

lol thanks for the tip on inserting!

What PHP version are you using?

chwebdesigns · February 25, 2008

Erm.... i honestly don't have a clue, I don't have loads of experience in PHP, just dribs and drabs. Whether this helps, here is a snippet from some of the previous code, it may help you work out which version! I feel so much like an idiot!!!

if(!$HTTP_POST_VARS['title']) {
echo "<h1 align=\"center\">You must enter a title <a href=\"javascript:history.back(-1)\"> Go back</a></h1>" ;
exit;
}
        if(!$HTTP_POST_VARS['news']) {
            echo "<h1 align=\"center\">You must enter some news <a href=\"javascript:history.back(-1)\"> Go back</a></h1>";
            exit;
        }

revraz · February 25, 2008

I just noticed you're using HTTP_POST_VARS which is pretty old and you should redo your code and change them out.

chwebdesigns · February 25, 2008

is this more up-to-date coding?

<?php
$name = $_POST['name'];
$title = $_POST['title'];
$anchor = $_POST['anchor'];
$news = $_POST['news'];
$password = md5($_POST['password']);
if($password == '20d96dc5d58462f86a37ad43dc1a7bf9') {
if($name == 'Select your name'){
echo "Please Select your Name";
}
if($title == ''){
echo "Please type a title";
}
if($anchor == ''){
echo "Please type an achor";
}
if($news == ''){
echo "Please enter some news";
}
else{
echo "Welcome $name ! You want to post some news with the title $title ";
}
}else {echo"Bad Password";}
?>

chwebdesigns · February 25, 2008

<?php
	$file = fopen ( $feedfile, "a");
	$feeddate = date("D, d M Y H:i:s");
	$content = "<item><title>$title</title><description>$news</description><link>$anchor</link><pubDate>$feeddate GMT</pubDate></item>";
	$closingtags = "</channel></rss>";
	$writing = str_replace($closingtags,$content);
	fwrite ($file, $writing"\n"$closingtags);
	fclose ($file);
	echo "News Created"; ?>

I have changed my code and used this, but it doesn't seem to work ???

This may be a little more than you want, but try substituting the MySQL call with your form data. Youu can always send your form data to the database and use php for the RSS feed.

try this

chwebdesigns · February 26, 2008

nothing seems to work when that happens, ??? ???

thanks anyway

uniflare · February 26, 2008

do you get any errors?

chwebdesigns · February 26, 2008

all i get is a blank white page. ------ That's what happens if i have errors in my code, on my old server, it used to tell me the errors, but since ive moved it doesn't which is a pain.

uniflare · February 26, 2008

try the following at the beginning of your scripts:

<?php

// Report all PHP errors (bitwise 63 may be used in PHP 3)
error_reporting(E_ALL);

// Same as error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);

?>

see if it shows errors

chwebdesigns · March 2, 2008

ok i have tried again, and inseted that code to look for errors, the doesn't seem to be any errors which come up (it says "News Created") but nothing is inserted into the rss feed

uniflare · March 5, 2008

try this

<?php
	$file = fopen ( $feedfile, "a");
	$feeddate = date("D, d M Y H:i:s");
	$content = "<item><title>$title</title><description>$news</description><link>$anchor</link><pubDate>$feeddate GMT</pubDate></item>";
	$closingtags = "</channel></rss>";
	$writing = str_replace($closingtags,$content."\n".$closingtags,$file);
	fwrite ($file, $writing);
	fclose ($file);
	echo "News Created"; ?>

i forgot arg 3 on str_replace

chwebdesigns · March 7, 2008

That inserts

Resource id #2Resource id #2

after the closing brackets.

Which has really left me stumped ???

uniflare · March 7, 2008

Sorry my bad again i havn't tested this code (obviously) but this should work now: (i forgot the fread function, look at www.php.net/fread for more info)

<?php
	$file = fopen ( $feedfile, "a");
	$contents = fread($file, filesize($feedfile));

	$feeddate = date("D, d M Y H:i:s");

	$content = "<item><title>$title</title><description>$news</description><link>$anchor</link><pubDate>$feeddate GMT</pubDate></item>";
	$closingtags = "</channel></rss>";

	$writing = str_replace($closingtags,$content."\n".$closingtags,$contents);
	fwrite ($file, $writing);
	fclose ($file);

	echo "News Created";
?>

hope this helps,

chwebdesigns · March 8, 2008

This stops adding the Resource Id# at the end of the code, but nothing is inserted now. Arrggghh ???

uniflare · March 8, 2008

lol lets debug this:

<?php
	$file = fopen ( $feedfile, "a+");
	echo($feedfile."<br />");

	$contents = fread($file, filesize($feedfile));
	echo($contents."<br />");

	$feeddate = date("D, d M Y H:i:s");
	echo($feeddate."<hr />");

	$closingtags = "</channel></rss>";
	$content = "<item><title>$title</title><description>$news</description><link>$anchor</link><pubDate>$feeddate GMT</pubDate></item>".$closingtags;

	echo($content."<hr />");

	$newfile = str_replace($closingtags,$content."\n".$closingtags,$contents);

	echo($newfile."<hr />");

	fwrite ($file, $newfile);
	fclose ($file);

	echo "News Created";
?>

tell us what the page says (the html source of the page to be precise)

chwebdesigns · March 8, 2008

hey, this is the HTML code i get

uniflare · March 9, 2008

ok i get it, there is a line break between </channel> and </rss> so the str_replace wont work, try:

<?php
	// Set current date for replacement/new content
	$feeddate = date("D, d M Y H:i:s");

	// set file path/filename
	$feedfile = "test.rss";
	$path = "./";

	// set replacement/new content
	$replacement = "<item>\r\n<title>$title</title>\r\n<description>$news</description>\r\n<link>$anchor</link>\r\n<pubDate>$feeddate GMT</pubDate></item>\r\n</channel>\r\n</rss>";

	// Get file contents
	$contents = file_get_contents($path.$feedfile);

	// set the REGEX Pattern used to find the closing tags, even if there are several line breaks and/or tabs between them.
	$preg_pattern = "/<\/channel>\r*\n*\t*<\/rss>/i";

	// Replace $preg_pattern with $replacement in the $contents variable set eariler use file_get_contents()
	$writing = preg_replace($preg_pattern,$replacement,$contents);

	// Write the new contents of the file
	$bytes = file_put_contents($path.$feedfile,$writing);

	// Echo with number of Bytes written to file
	echo "News Created, $bytes bytes written";
?>

i scrapped fopen way and used file_get_contents/file_put_contents - seemed a little neater/easier to look at and understand, this way the file_put_contents with Overwrite any contents already in the file.

Tested on Apache 2.2.8/PHP mod_ssl/2.2.8 OpenSSL/0.9.8e PHP/5.2.5 on a XP x64 system

hope this helps,
