<snippet src="original message">
"
if I use ($numrows == 0) then
it displays the warning text saying nothing is in the category,

should be
if ($numrows == 0) {
comparison, rather than assignment.

Hello all ( at least I hope it is getting somewhere, my last few emails
disappeared)
Got an irritating little problem that is starting to drive me up the
wall, I am making an online catalogue for a client
using PHP and MySQL to populate the pages. I want the code to check to
see if any rows were returned by the query
and, if not, display a message saying that the category is emtp.. easy
right? just simple case of using mysql_num_rows() on the
query result string and whalah.. but it is being stubborn.
mysql_num_rows is returning a blank string instead of 0 or the number
of rows actually there. Heres a snippet of the code
<snippet begins>
$sql = sprintf("SELECT * FROM CatalogueItems WHERE
fldcategory=`%s`",$category);
$result = mysql_query($sql);
if (!$result) { die("Database Connection Error, Contact the site
administrator"); }
$numrows = mysql_num_rows($result);
if ($numrows = 0) {
echo '<center><font color="red" style="font-weight: bolder">No items
exist for this category</font><br>
<br><a href="./index.php" class="itemlist">Back to home
page</a></center>';
} else {
.// fetch results arrays and create dynamic page
.
.
.
}
</snippet>
One category is empty and another has 6 rows, but when doing this code
on either of the categories, mysq_num_rows returns " " instead of an int
value, so nothign whatsoever is displayed. if I use ($numrows == 0) then
it displays the warning text saying nothing is in the category, if I use
($numrows < 1) it displays nothing whatsoever. I have tried debugging by
putting dynamic comments in the code, but the value output by
mysql_num_rows is always a blank space.
Any help on this before i go completely nuts is appreciated much in advance.
