Hello,

I use php/mysql for several years, and there, an error without
explanation.

The PHP script below inserts an record two times, the same two times.
Why ? Any idea ?

Thank you
Francois


include ('connecte.csv');
$link = mysql_connect($sql,$user,$pwd) or die("ERROR");
mysql_select_db($db,$link);
mysql_query("insert into listescouts (categorie,nom) values
('test','essai')",$link);
mysql_close($link);

With another table, no problem. Both tables were built in the same time
(different fields of course)

It won't, unless you're calling the script twice.

Echo a message every time you execute it and see what you get.

Only one time, I'm sure.

Nothing, the script is simple and without problem in its syntax

"Insert into"... inserted in phpmyadmin is ok : only one record
inserted, but with the previous php script, it's bad (although with
another table, it's ok)

The script most likely is called twice.

The code you posted will only insert twice if you call it twice.

Try putting the following in your code:

echo "I'm inserting a new record now<br>\n";

And see if you don't get two messages.

Either that or you're inserting in another place, also. Comment out the
mysql_query statement and see if it's getting inserted at all.

One or the other is happening.

add timestamp to your query, you will be able to compare time of inserted
values.
if script is called two times it will be visible as two diffirent
timestamps.

I don't think so because there is only a mysql_query instruction. What
do you think ,
Thanks

thanks but the result is not very significant because it's measured in
second not in milliseconds
