Hi,
I'm really new and getting lots of help but need some assistance.
I'm running a script which gets specific articles from a database if
they're entered in the URL after the ? . For instance if someone asks
for
www.foo.com/index.htm?a=1234
then the script would look for an database entry with the id of 1234
and display it in the page.
If there's no number specified (www.foo.com/index.htm) or if the number
given is to an article which doesn't exist, it gets the titles of all
the articles available and prints them as links to the proper article
number.
I'd also like it to grab the first 200 characters of text from the
$content field of the entry.
With help I have the title link part and I suspect I'm close but I keep
messing up the syntax
The code is:
<snip>
if (!empty($where)) {
echo "
 <ul>";
  $article = mysql_fetch_assoc($result);
} else {
while ($article = mysql_fetch_assoc($result)) {
  $table_of_contents[] = "
<li><a href='{$_SERVER['PHP_SELF']}?a={$article['article_id']}'

title='{$article['title']}'>{$article['title']}</a><br />
$article['content'] = substr($article['content'], 0 200);</li>";
change these two lines to
title='{$article['title']}'>{$article['title']}</a><br />".
substr($article['content'], 0, 200)."</li>";

I did that and now it reads this:

if (!empty($where)) {
echo "
 <ul>";
 $article = mysql_fetch_assoc($result);
} else {
while ($article = mysql_fetch_assoc($result)) {
 $table_of_contents[] = "
<li><a href='{$_SERVER['PHP_SELF']}?a={$article['article_id']}'
<li><a href='{$_SERVER['PHP_SELF']}?a={$article['article_id']}'
title='{$article['title']}'>{$article['title']}</a><br />".
substr($article['content'], 0, 200)."</li>";
}
}
\
Which doesn't kick back errors but also does not pull any 
$article['content'] - it leaves a line break but no text is being 
inserted from the content row.
