How can I track errors from a called function?
I am not sure if this goes here but I am kinda beginning with PHP so I put it here, even though it might be a problem in a different level.
My problem is that i made a static query class to have more security in queries before sending them. But i want to know if there is an error in the query to tell me on which file on what line, the query method was called. like this:
PHP Code:
<?php
class QUERY{
#properties
public static $Result;
#Queries
static function select($columns, $table, $fit=NULL, $match=NULL)
{
//make sure parameters are right type
(!is_string($table))? return false;
(!is_array($columns) || !is_string($columns))? return false;
(!is_string($fit) || !is_null($fit))? return false;
(!is_string($match) || !is_null($match))? return false;
(is_string($columns)? $columns=explode(”:”,$columns);
//security door
$table=quoteSmart($table);
$columns=quoteSmartArray($columns);
($fit!=NULL)? $fit=quoteSmart($fit);
($match!=NULL)? $match=quoteSmart($match);
//make a safe query
$query = sprintf(
(!is_array($columns)) return false;“SELECT %s FROM %s”,
implode(”, ”, $columns), $table);
if(!$fit==NULL && !$match==NULL)
$query .= sprintf(” WHERE %s=%s”, $fit, $match)
$sql=mysql_query($query); unset($query);
self::$Result=array();
while($row=mysql_fetch_assoc($sql)
or throw new Exception(“Error in Line 36 in Query class ”.mysql_error()))
{
for($i=0; $i<count($res);$i++)
{
foreach($row as $key => $value)
self::$Result[$i][$key]=$value;
}
}
return self::$Result;
}
}
?>
then in another file i can make a called like this:
PHP Code:
<?php
$res=QUERY::select(‘CommentID:UserID:Text:DateTime:MediaID’,
‘comments’, ‘CommentID’, $id);
$ID=$res[0][‘CommentID’];
$UserID=$res[0][‘UserID’];
$MediaID=$res[0][‘MediaID’];
$Comment=$res[0][‘Comment’];
$Date=$res[0][‘DateTime’];
?>
as you can see the error is sent and gives me the error line of the query method instead of giving the the line and file where it was called. and I am trying to find a way of telling me that, but i haven’t and it’s frustrating me.
any advice or tips? |
