function not working properly, codeigniter - php

Question

The function is fetching data from the database, but the issue is, it is not fetching the next row after printing the first row.
Kindly check and tell me what I'm doing wrong?
Public function Return_Config($P_name, $WW, $KPI) {
log_message('debug', 'hd');
log_message('debug', $P_name . ' ' . $WW . ' ' . $KPI);
$P_name .= '_one_voice_perf_measured';
$select_query = "SELECT config FROM $P_name WHERE KPI = '$KPI' AND Config = '$WW'";
//echo $select_query;
$query = $this->db->query($select_query);
if ($query->row() > '0') {
return $query->row()->config;
} else {
return 'Not Measured';
}
}
It is going directly to the else part. please help

Answer 1

This is because you are using ->row() instead use ->result(), like:
Public function Return_Config($P_name, $WW, $KPI)
{
log_message('debug', 'hd');
log_message('debug', $P_name . ' ' . $WW . ' ' . $KPI);
$P_name.= '_one_voice_perf_measured';
$select_query = "SELECT config FROM $P_name WHERE KPI = '$KPI' AND Config = '$WW'";
// echo $select_query;
$query = $this->db->query($select_query);
if (!empty($query->result()))
{
return $query->result();
}
else
{
return 'Not Measured';
}
}

try this
Public function Return_Config($P_name,$WW,$KPI){
log_message('debug','hd');
log_message('debug', $P_name.' '.$WW.' '.$KPI);
$P_name .= '_one_voice_perf_measured';
$select_query = "SELECT config FROM $P_name WHERE KPI = '$KPI' AND Config = '$WW'";
//echo $select_query;
$query = $this->db->query($select_query)->row_array();
if (!empty($query)){
return query['config'];
}
else{
return 'Not Measured' ;
}
}
