RON_ron Posted August 12, 2010 Share Posted August 12, 2010 Why doesn't this code update two mysql databases (on two servers)? What am I doing wrong? //SERVER 1 $link = mysql_connect("localhost","usern1","pw1"); mysql_select_db("db_one1"); //SERVER 2 $link = mysql_connect("xxx.xxx.xx.xxx","usern2","pw2"); mysql_select_db("db_one2"); $query = "INSERT INTO db1(subject, search, News, img) VALUES('$hsubject','$key','$news','$img')"; $result = mysql_query($query); $query = "INSERT INTO db2(subject, search, News, img) VALUES('$hsubject','$key','$news','$img')"; $result = mysql_query($query); $sentOk = "The data has been added to the database."; echo "sentOk=" . $sentOk; Quote Link to comment https://forums.phpfreaks.com/topic/210546-why-doesnt-this-script-function/ Share on other sites More sharing options...
trq Posted August 12, 2010 Share Posted August 12, 2010 Your saving both connections within the one variable called $link. Hence, the second connection overrides the first. You then fail to pass any specific connection to mysql_query.

Rohlan Posted August 12, 2010 Share Posted August 12, 2010 Your code should look more like this: (didn't proof read it) //SERVER 1 $link = mysql_connect("localhost","usern1","pw1"); mysql_select_db("db_one1"); $query = "INSERT INTO db1(subject, search, News, img) VALUES('$hsubject','$key','$news','$img')"; $result = mysql_query($query); //SERVER 2 $link = mysql_connect("xxx.xxx.xx.xxx","usern2","pw2"); mysql_select_db("db_one2"); $query = "INSERT INTO db2(subject, search, News, img) VALUES('$hsubject','$key','$news','$img')"; $result = mysql_query($query); $sentOk = "The data has been added to the database."; echo "sentOk=" . $sentOk; Because you rewrite the $link variable on the second connection... This way you connect to the first db then send the info... then connect to second db and send info.

PradeepKr Posted August 12, 2010 Share Posted August 12, 2010 check correct syntax http://php.net/manual/en/function.mysql-query.php and http://www.php.net/manual/en/function.mysql-select-db.php //SERVER 1 $link = mysql_connect("localhost","usern1","pw1"); mysql_select_db("db_one1", $link); $query = "INSERT INTO db1(subject, search, News, img) VALUES('$hsubject','$key','$news','$img')"; $result = mysql_query($query, $link); if(mysql_num_rows($result) == 0) { $sentOk = "The data has been added to the database."; echo "sentOk=" . $sentOk; } //SERVER 2 $link = mysql_connect("xxx.xxx.xx.xxx","usern2","pw2"); mysql_select_db("db_one2", $link); $query = "INSERT INTO db2(subject, search, News, img) VALUES('$hsubject','$key','$news','$img')"; $result = mysql_query($query, $link); if(mysql_num_rows($result) == 0) { $sentOk = "The data has been added to the database."; echo "sentOk=" . $sentOk; } Quote Link to comment https://forums.phpfreaks.com/topic/210546-why-doesnt-this-script-function/#findComment-1098467 Share on other sites More sharing options...
RON_ron Posted August 12, 2010 Author Share Posted August 12, 2010 Thanks mates! Before trying these, Just one more thing..... Do I have to give permission to update an MYSQL? E.g. If I'm on server 1 and using this script to update the mysql on server 1 and server 2.

trq Posted August 12, 2010 Share Posted August 12, 2010 Do I have to give permission to update an MYSQL? Of course, as always, you need permissions to execute the queries. If its a remote server, you'll need permissions just to connect to it.
