What is the error?

If you display $arr and $dep to the screen to see if they contain what you expect?

amey1309 · May 9, 2012

$arr and $dep are displaying the correct value if I print them but the query is not getting executed.

$query=mysql_query("SELECT count(*) FROM `room_inventory` WHERE room_no='$a' and ((arrival<='$arr' AND departure>='$arr')OR(arrival<='$dep' AND departure>='$dep'))")

where as if I try the hard code as below,it is working perfectly fine displaying the correct info as one would get after runnung the same query in My sql.

$query=mysql_query("SELECT count(*) FROM `room_inventory` WHERE room_no='$a' and ((arrival<='2012-05-11' AND departure>='2012-05-11')OR(arrival<='2012-05-13' AND departure>='2012-05-13'))");

Note:Am formatting the date as yyyy-mm-dd from dd/mm/yyyy as My sql demands it.You can get date formatting function in my first post.

PFMaBiSmAd · May 9, 2012

You need to form the query statement in a php variable (you have done that in at least one place), echo the resulting query statement, and post it so that someone here could actually see what it is.

Edit: Also, what is the actual data type of the columns you are storing the dates in?

darkfreaks · May 9, 2012

cleaned up some redundancy in your code. not sure why the backticks are there i took them out.

let us know if you have more problems.

Oh at last I got the error.It is the variable scope.I need to specify both $arr and $ dep as Global before using it inside a function.

Thanks you all for your precious advice and time
