Please ignore everything I said and go here: http://www.php.net/support This is not a bug in PHP. Previous Comments: ------------------------------------------------------------------------ [2002-12-26 12:07:08] [EMAIL PROTECTED] This is what my code looks like now: <? trim($searchterm); if(!$searchtype || !$searchterm) { echo "You have not entered search details. Please go back and try again."; exit; } $searchtype = addslashes($searchtype); $searchterm = addslashes($searchterm); @ $db = mysql_connect("localhost", "headdive_jazz", "jazz"); if(!$db) { echo "Error: Could not connect to database. Please try again later."; exit; } mysql_select_db("books"); $query = "SELECT count(*) FROM books WHERE $searchtype LIKE '%$searchterm%'"; if(!$result = mysql_query($query)) { print mysql_result($result, 0); exit; } $num_result = mysql_num_rows($result); echo "<p>Number of books found: ".$num_results."</p>"; for($i=0; $i < $num_results; $i++) { $row = mysql_fetch_array($result); echo "<p><strong>".($i + 1).". Title: "; echo htmlspecialchars(stripslashes($row["title"])); echo "</strong><br>Author: "; echo htmlspecialchars(stripslashes($row["author"])); echo "<br>ISBN: "; echo htmlspecialchars(stripslashes($row["isbn"])); echo "<br>Price: "; echo htmlspecialchars(stripslashes($row["price"])); echo "</p>"; } ?> and this is the response I get: Warning: mysql_result(): supplied argument is not a valid MySQL result resource in /bookorama/results.php on line 29 ------------------------------------------------------------------------ [2002-12-26 11:49:50] [EMAIL PROTECTED] You can't have spaces in column names, your query is bogus. And btw I just noticed your typo: $searchtype = addslashes($searchtype); $searchtype = addslashes($searchterm); // notice the problem? Anyway, this is bogus. ------------------------------------------------------------------------ [2002-12-26 10:55:15] [EMAIL PROTECTED] Okay, I did the first rewrite and I got the below output. Could not run query (select * from books where Java 2 like '%Java 2%') : You have an error in your SQL syntax near '2 like '%Java 2%'' at line 1 Then I tried the second rewrite and I got the one below. Warning: mysql_result(): supplied argument is not a valid MySQL result resource in /bookorama/results.php on line 32 ------------------------------------------------------------------------ [2002-12-26 10:39:28] [EMAIL PROTECTED] Rewrite this: $result = mysql_query($query); Like this: if (!$result = mysql_query($query)) { print "Could not run query ($query) : " . mysql_error(); exit; } If that doesn't output something, try and rewrite your query like so: $query = "SELECT count(*) FROM books WHERE $searchtype LIKE '%$searchterm%'"; And get the count by: if ($result = mysql_query($query)) { print mysql_result($result,0); exit; } Anyway this looks like a support question but just in case try the above. I'm guessing the query is invalid, like, $searchtype is not defined correctly or something. In which case you'd be giving mysql_num_rows() a invalid mysql result resource because mysql_query() retured false on the bogus query. And BTW, you want && not ||. Error handling is your friend. Like for example, make sure $searchtype is a column you want to use. Anyway, when in doubt, print stuff. ------------------------------------------------------------------------ [2002-12-26 09:45:49] [EMAIL PROTECTED] I have a very simple PHP script, that searches a small mysql database for a result. And the result that I keep receiving pertaining to the mysql_num_rows() function is listed below. Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /bookorama/results.php on line 29 Number of books found: Here is some of the PHP script. <? trim($searchterm); if(!$searchtype || !$searchterm) { echo "You have not entered search details. Please go back and try again."; exit; } $searchtype = addslashes($searchtype); $searchtype = addslashes($searchterm); @ $db = mysql_connect("localhost", "headdive_jazz", "jazz"); if(!$db) { echo "Error: Could not connect to database. Please try again later."; exit; } mysql_select_db("books"); $query = "select * from books where ".$searchtype." like '%".$searchterm."%'"; $result = mysql_query($query); $num_result = mysql_num_rows($result); echo "<p>Number of books found: ".$num_results."</p>"; for($i=0; $i < $num_results; $i++) { $row = mysql_fetch_array($result); echo "<p><strong>".($i + 1).". Title: "; echo htmlspecialchars(stripslashes($row["title"])); echo "</strong><br>Author: "; echo htmlspecialchars(stripslashes($row["author"])); echo "<br>ISBN: "; echo htmlspecialchars(stripslashes($row["isbn"])); echo "<br>Price: "; echo htmlspecialchars(stripslashes($row["price"])); echo "</p>"; } ?> ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=21198&edit=1
