Question

Insert RSS into mysql Database

Asked by: rhiannon1

I am trying to save some XML/RSS data from my page into my MYSQL datasbse using PDO.

I have finaly parsed and external RSS feed and i am displaying the articles on my site. /all is working fine so far in that respect. Now what i want to do, but unable to figure out how to do it is this.

Each article dispayed on my page has a checkbox next to it, and a submit button on the bottom of the page, I want to beable to have a user, check articles and then save articles into my mysql database,  which they will beable to retrieve at a later date.

I want to save to a table called 'articles'  the title, link, and cateogory(which will be either smoking or neuroscience) also need to retrieve the full article and save that to the field 'body'.  

So at the moment the title and link are being shown on my page, ( <a href='$friendly'>$RSSitem->title</a>), but how do i save to the database, and also pull out and save the whole document body. i.e http://www.medicalnewstoday.com/printerfriendlynews.php?newsid=134827.

Really stuck on this, I have got so far, now just hit the brick wall : (   any ideas ?

Thank You. 

<?PHP
 
require_once("dbCon/dbcon.php");
 
try {
/*  query the database */
$db = getCon();
 
/* Parse XML from  http://www.medicalnewstoday.com */
$RSS_DOC = simpleXML_load_file('http://www.medicalnewstoday.com/rss/smoking.xml');
 
/* Get title, link, managing editor, and copyright from the document  */
$rss_title = $RSS_DOC->channel->title;
$rss_link = $RSS_DOC->channel->link;
$rss_editor = $RSS_DOC->channel->managingEditor;
$rss_copyright = $RSS_DOC->channel->copyright;
 
//Loop through each item in the RSS document
 
foreach($RSS_DOC->channel->item as $RSSitem) {
// modify string from articles  //
$friendly = str_replace(array('.php', 'articles/'), array('', 'printerfriendlynews.php?newsid='), $RSSitem->link);
 
//  form //
$page->addToContent("<form action='rssNeuroScience.php' method='post' />");
	
	//The variable $RSSitem will hold a different item for each loop
		$page->addToContent("<b><a href='$friendly'>$RSSitem->title</a></b><br /><br />");
		$page->addToContent("<b>$RSSitem->pubDate</b><br /><br />");
		$page->addToContent("$RSSitem->description<br /><br />");
		$page->addToContent("<input name='cBox' type='checkbox' value='cBox'/><br />");
		//$page->addaddToContent("-------------------------------------------------------------<br />");
}
$page->addToContent("<input type='submit' value='submit'/></form>");
// End of form //
 
?>

Suggest you try it this way, in several steps.  

First off, you might want to save ALL the articles in the data base.  You will give each one an article-id, UNIQUE.  You would not want to save the articles individually - that would probably lead to saving the same article more than once.

To grab the entire article, you can do this:
$html = file_get_contents("http://www.medicalnewstoday.com/printerfriendlynews.php?newsid=134827");

Next you want to create a table of "my_saved_articles"  It will contain the user-id and the article-id.

To find anyone's articles, you SELECT article-id FROM my_saved_articles WHERE user-id = [your client].

You might want a garbage collection scheme that periodically looks through the articles, selecting the user_id from my_saved_articles where article-id = current article and save-date > 30 days ago.  If there is nothing in the query result set, you know that nobody checked that article.  That way you can delete old articles that did not capture anyone's fancy.

To put up a form with information from checkboxes,  you can do something like this:

<input type="checkbox" name="article<?php echo $article_id;?>" />

To find which articles were checked, you can do this sort of thing in the action script:

foreach ($_POST as $key => $value)
{
   if substr($key,0,7) != 'article') continue;
   $article_id = (int)substr($key,7,999);
   $sql = "INSERT INTO my_saved_articles (user_id, article_id) VALUES ($user_id, $article_id)";
}

This works because if a checkbox is not checked, there is nothing for it in the $_POST array.

Hope that helps get your thinking flowing again! ~Ray
