jntcomputers Posted March 26, 2006 Share Posted March 26, 2006 I am trying to tak emultiple entries and add values from the same user into one value. I have this code:[code]$sql_select = "SELECT user_id, start_time, end_time FROM default_ScheduleEvents WHERE (school_id = $this_school)"; $recordSet_select = $conn->Execute($sql_select); if ($recordSet_select === false) { //log_error($sql);mysql_error(); } $num_records = $recordSet_select->RecordCount(); if ($num_records > 0) { $hours_array = array(); while (!$recordSet_select->EOF) { $this_pilot_id = make_db_unsafe ($recordSet_select->fields[user_id]); $st_time = strtotime(make_db_unsafe ($recordSet_select->fields[start_time])); $en_time = strtotime(make_db_unsafe ($recordSet_select->fields[end_time])); $this_date = DATE("M-d-Y",$st_time); $flight = ($en_time - $st_time)/3600; //$flight_time = DATE("g:i",strtotime($flight)); $sql2 = "SELECT field_name, field_value FROM default_UserDBElements WHERE (user_id = $this_pilot_id)"; $recordSet2 = $conn->Execute($sql2); if ($recordSet2 === false) { //log_error($sql);mysql_error(); } while (!$recordSet2->EOF) { if ($recordSet2->fields[field_name] == "name"){ $pilot_name = $recordSet2->fields[field_value]; }; $recordSet2->MoveNext(); } // end while if ($pilot_name != "") { if(isset($hours_array[$pilot_name])){ //...add the current hour value to the //existing value.. $hours_array[$pilot_name] += $flight; } else { //if the name isn't there, then add it and //give it the value of the hours $hours_array[$pilot_name] = $flight; } echo "<tr><td class=\"dispatch_flight\">$this_date</td><td class=\"dispatch_flight\">$pilot_name</td><td class=\"dispatch_flight\">$hours_array[$pilot_name]</td></tr>";} // end if pilot != "" $recordSet_select->MoveNext(); } // end while } // end if number > 0echo "</tr></table>";?>[/code]But it outputsUser Name : HoursUSER 1 : 1.5USER 1 : 7.5When the table values are 1.5 & 6. So it is adding them, but I can't figure out how to show the user name only once.

mb81 Posted March 26, 2006 Share Posted March 26, 2006 OK, where do we start?1) You can use a query that is a little bit more complex to get all the information into 1 query. I am having a really hard time figuring out your data structure because of all your code crap, so I can't help you there.2) If you don't want to make the MySQL query more complex, then take this section: [code]echo "<tr><td class=\"dispatch_flight\">$this_date</td><td class=\"dispatch_flight\">$pilot_name</td><td class=\"dispatch_flight\">$hours_array[$pilot_name]</td></tr>";[/code]And put it at the end into a foreach loop. [code]foreach ($hours_array AS $pilotname=>$hours) { echo "<tr><td class=\"dispatch_flight\">$pilotname</td><td>$hours</td></tr>";}[/code] Quote Link to comment https://forums.phpfreaks.com/topic/5862-adding-values-from-query/#findComment-20934 Share on other sites More sharing options...
