Need help with this error. Can't see what's wrong.
Error:
Warning: mysql_query() expects parameter 1 to be string, resource given in C:\wamp\www\pm website\php\bulletin_board\bulletin_board.php on line 48
Code:
<?php
$con = mysql_connect("localhost","root",""); //Databse connection

$view = mysql_query("SELECT * FROM bulletin ORDER BY pro_no DESC"); //Selecting the table from the DB
if (!mysql_query ($view, $con))

You wrote this:
$view = mysql_query("SELECT * FROM bulletin ORDER BY pro_no DESC"); //Selecting the table from the DB
if (!mysql_query ($view, $con))
Notice how you execute the query, assign its result resource to $view
, then try to run another query with $view
as the SQL? But $view
is not SQL, it's a result resource, hence the error.
Just write this:
$view = mysql_query("SELECT * FROM bulletin ORDER BY pro_no DESC");
if (!$view)
you can't query result of your query. try this one
$view = mysql_query("SELECT * FROM bulletin ORDER BY pro_no DESC"); //Selecting the table from the DB
if (!$result)
it should do the magic
You actually have two queries. The second query is executed in the if-statement:
if (!mysql_query ($view, $con))
Notice that $view here is of type resource, not of type string. If you want to check that the query executed correctly, just write:
if(!$view)
