First of all, echo the output to see if You get, what Tou expect in a debug
situation:
if (!empty($where)) {
echo
ul;
$article = mysql_fetch_assoc($result);
} else {
while ($article = mysql_fetch_assoc($result)) {
// humanize data
$article_id = $article['article_id'];
$title = $article['title'];
$content = substr($article['content'], 0 200); // get first 200 chars
// print and see if we get, what we expect
Print id=$article_idbrtitle=$titlebrcontent=$contentp;
// now make the real stuff
print lia href='{ . $_SERVER['PHP_SELF'] .
}?a={$article_id}'}title='{$title}'{$article['title']}/abr
/\n$content/li;
}
}
echo
/ul;
I´ve put the in front of title since the link otherwise would be a
href=a=1234title=sometext, which is not what You want I guess.
And I substituted the
$article['content'] = substr($article['content'], 0 200);/li; } }
with
$content/li;
since I believe You want to print the content and not just assign it? Otherwise
the br / makes no sense :-)
Can anyone help ?
I hop that did the trick for You :-)

Like a comma.
Look between your 0 and 200 very carefully.

[PHP] Re [PHP] Newbie Question re substr: Solved
Sorry if this posts twice. Thanks everyone for the help.
The missing comma was the problem with the display; the missing
specification of the column at the start of the sql query was the
problem with getting the data from the column.
Again, thanks all who replied for the fast and excellent help.

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[] =

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

}
}
echo
/ul;
/snip
Can anyone help ?
Thanks in advance!

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)) {
$table_of_contents[] =
lia href='{$_SERVER['PHP_SELF']}?a={$article['article_id']}'
lia href='{$_SERVER['PHP_SELF']}?a={$article['article_id']}'
title='{$article['title']}'{$article['title']}/abr /.
substr($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.
