Thanks Rami,
I knew from the echoes that my statements were valid. Unfortunately,
the mysrc class doesn't seem to agree with me :-(
To recap. No matter what I try I just can't seem to pass this...
foreach ($_GET as $condition_key => $condition_value) {
$condition[] =" `$condition_key` = '$condition_value' ";
$condition_keys[] = "$condition_key";
$condition_values[] = "'$condition_value'";
}
if(is_null($condition)){
$conditionString = " 1 ";
}else{
$conditionString = implode('AND', $condition);
$conditionKeysString = implode(',',$condition_keys);
$conditionValuesString = implode(',',$condition_values);
}
as arguments to this...
class mysrc extends drasticsrcmysql {
protected function select($conditionString){
$query = "SELECT * FROM $this->table WHERE $conditionString";
$res = mysql_query($query . $this->orderbystr, $this->conn) or
die(mysql_error());
return ($res);
}
protected function add($conditionKeysString,$conditionValuesString){
$query = "INSERT INTO $this->table ($conditionKeysString) VALUES
($conditionValuesString)";
mysql_query($query, $this->conn) or die(mysql_error());
if (mysql_affected_rows($this->conn) == 1) return(true); else
return(false);
}
....unless I pass a bogus column name: Unknown column
'false_column_name' in 'where clause'
