Re: [PHP] simple question abt convert to integer
Problem solved succesfully after changed the query integer apostrofyless.. and printed the mysql_errno() and mysql_error()... Remember: -In the script languages as php the apostrofy ' or " or sg. like these means the string marker... -While ure developing show all error codes and messages... -If ur query contains errors u'll not get the resource id to use just a false boolean... -..and always check u don't have empty variables... :D Let's ride PHP!

The above is silly. Think about it: you're sending a string to MySQL. If $_POST['txt'] returns a string which looks like the number 1, then $query1 = "select * from patient where id = $_POST[txt]"; should suffice. If you like, test $_POST['txt'] first by echoing it. > echo $query1; > $result1=mysql_query($query1); Ideally, you should be calling this function with an added "connection" parameter. Like this: $link = mysql_connect($connection_stuff); $result1 = mysql_query($query1, $link); It's not *necessary*, but advisable. mysql_query() returns a "resource" object, unless there is a problem. If there is a problem, then it returns FALSE. You can check what it returns this way: if (is_resource($result1)) print "It's a resource!"; elseif ($result1 === FALSE) print "It's false!"; else print "I don't know what the heck it is!"; > > echo $result1; I don't know what you'll get from this "echo" if $result1 truly is a resource. But if it's false, you won't get much. $result1 should be a "resource" object, which means it's opaque. You can't know what's in it unless you use a "helper" function like mysql_num_rows(), etc. > $num2=Mysql_num_rows($result1); > $num3=Mysql_num_fields($result1); > > still it has previous error > > Here is my output:select * from patient where id=1 > *Warning*: mysql_num_rows() expects parameter 1 to be resource, boolean > given in > > *Warning*: mysql_num_fields() expects parameter 1 to be resource, boolean > given in ** Your error messages clearly mean that 1) you're not getting a proper resource object back from mysql_query(), or 2) you're somehow changing $result1 into a boolean before passing it to these other functions. But I suspect it's #1 above. Please see the documentation for these functions at php.net. It may even be available in your native language. Paul -- Paul M.

Re: [PHP] simple question abt convert to integer
i recieve nothing not a resource id and nore false
Re: [PHP] simple question abt convert to integer
If the query is incorrect u get boolean: false, if its correct u get a resource id... Bálint Horváth On 25 May 2011 06:28, "Negin Nickparsa" wrote:

Bálint Horváth, the second post of me is using your idea your idea is working but why i have error still?

$id=(int)$_POST['txt']; $query1="select * from patient where id=".$id.""; echo $query1; $result1=mysql_query($query1); echo $result1; $num2=Mysql_num_rows($result1); $num3=Mysql_num_fields($result1); still it has previous error Here is my output:select * from patient where id=1 *Warning*: mysql_num_rows() expects parameter 1 to be resource, boolean given in *Warning*: mysql_num_fields() expects parameter 1 to be resource, boolean given in **
Re: [PHP] simple question abt convert to integer
Hi, I've a simply idea... If you have integer in your mysql, don't use " at that field in the query... Try this: $query="select * from patient where id=".$id.""; There isn't apostrofy in the mysql query...

[PHP] simple question abt convert to integer
my code is this: $query1="select * from patient where id=".$_POST['txt']; it works but i think because i have error in next line: *Warning*: mysql_num_rows() expects parameter 1 to be resource, boolean given $num2=Mysql_num_rows($result1); i echoed $ query1 and the result was this=>select * from patient where id=1 maybe it can't convert $_POST['txt'] from String to integer and then it can't get my $num it is int in my mysql how can i correct $query1?
[PHP] about php comet

David David: I think the point here is that the documentation says the function returns a number greater than zero, or less than zero, or zero. It's just that many who have responded on this list show that the function commonly returns -1, 1, and 0. It's wise to keep with the documentation.

My result is:
13 -17 1
I'm runninng PHP 5.2.14 on the ARM Linux with uClibc.
Certainly the result depends on architecture and/or libc, because PHP just
calls system strcmp, nothing more.
So. to write compatible scripts one should check "< 0", not "== -1".
