problem with mysql error checking

Copy linkTweet thisAlerts:

Hi,

I have created myself some mysql function to make it easier when calling mysql data.

The problem I get is that if the value of the field is 0 then it picks it up as an error and fires it over to sqlerrorhandler function. When it is actually working just the fields value is 0.

[code=php]
function mysqlresult($queryresult, $field, $file, $function, $line, $sql) {

$sqlresult = @mysql_result($queryresult, 0, $field);

if (!$sqlresult) {
sqlerrorhandler(“(“.mysql_errno().”)”,”S0006″, mysql_error(), $file, $function, $line, $sql);
} else {
return $sqlresult;
}
}
[/code]

The same issue occurs if num rows equals 0 too.

Any help would be great,

Thanks

@TecBratMar 04.2009 — Zero is boolean false. You might try [code=php]//snip
if ($sqlresult===FALSE){
[/code]

Tripple equal checks for exact type and value match.

@Phill_PaffordMar 04.2009 — You might try this as well

[CODE]
// You have
$sqlresult = @mysql_result($queryresult, 0, $field);

// Try this
$sqlresult = mysql_result($queryresult, 0, $field);
[/CODE]

I believe the @ symbol is used to suppress error warnings. Your query could be throwing an error and it's not being passed back and that is why it's failing.

Success!
