AyKay47 Posted July 21, 2011 Share Posted July 21, 2011 okay so you would do something like this i believe.. $checkbox = $_POST['checkbox']; //depends on what method you used..$_GET or $_POST foreach($checkbox as $value){ $sql = "INSERT INTO tbl_name VALUES('$value')"; //insert correct values.. $query = mysql_query($sql) or trigger_error("Mysql Error:".mysql_error(),E_USER_ERROR); } Link to comment https://forums.phpfreaks.com/topic/242573-looping-through-checkboxes-please-help/#findComment-1245859 Share on other sites More sharing options...

teynon Posted July 21, 2011 Share Posted July 21, 2011 You're referencing the same variable all three times. You need to check it against all results in the database. You could try something like this: SQL: SELECT GROUP_CONCAT(start_time) FROM aarbookts_booking_bookings_slots WHERE booking_id = '$booking_id' Then in your code do: $row1 = mysql_fetch_array($query1); $times=explode(",", $row1); <input type="checkbox" name="Times" value="07:00:00" <?php if(in_array("07:00:00",$times){ echo 'checked';} ?>> 07:00 - 10:00<br /> <input type="checkbox" name="Times" value="10:00:00" <?php if(in_array("10:00:00",$times){ echo 'checked';} ?>> 10:00 - 13:00<br /> <input type="checkbox" name="Times" value="13:00:00" <?php if(in_array("13:00:00",$times){ echo 'checked';} ?>> 13:00 - 16:00<br /> <input type="checkbox" name="Times" value="16:00:00" <?php if(in_array("16:00:00",$times){ echo 'checked';} ?>> 16:00 - 19:00<br /> ^^ Not tested Link to comment https://forums.phpfreaks.com/topic/242573-looping-through-checkboxes-please-help/#findComment-1245933 Share on other sites More sharing options...

teynon Posted July 22, 2011 Share Posted July 22, 2011 I already explained why your code doesn't work. I also said that my code wasn't tested. It was meant as an example for how to do it. You get a white page because you have PHP Error reporting turned off. ini_set('display_errors', 1); ini_set('log_errors', 1); ini_set('error_log', dirname(__FILE__) . '/error_log.txt'); error_reporting(E_ALL); Your code doesn't work because you are essentially doing this: $row1['start_time']="07:00:00"; if ($row1['start_time']=="07:00:00") echo "echecked"; // Evaluates as true 07:00:00 == 07:00:00 if ($row1['start_time']=="10:00:00") echo "echecked"; // Evaluates as false 07:00:00 != 10:00:00 If you would do a little debugging on the code I posted, you would probably see that it does work. <?php $query1 = mysql_query("SELECT GROUP_CONCAT(start_time) FROM aarbookts_booking_bookings_slots WHERE booking_id = '$booking_id'"); $row1 = mysql_fetch_array($query1); $times=explode(",", $row1); ?> <input type="checkbox" name="Times" value="07:00:00" <?php if(in_array("07:00:00",$times){ echo 'checked';} ?>> 07:00 - 10:00<br /> <input type="checkbox" name="Times" value="10:00:00" <?php if(in_array("10:00:00",$times){ echo 'checked';} ?>> 10:00 - 13:00<br /> <input type="checkbox" name="Times" value="13:00:00" <?php if(in_array("13:00:00",$times){ echo 'checked';} ?>> 13:00 - 16:00<br /> <input type="checkbox" name="Times" value="16:00:00" <?php if(in_array("16:00:00",$times){ echo 'checked';} ?>> 16:00 - 19:00<br /> Link to comment https://forums.phpfreaks.com/topic/242573-looping-through-checkboxes-please-help/#findComment-1246092 Share on other sites More sharing options...

jarv Posted July 22, 2011 Author Share Posted July 22, 2011 Thanks for your help so far Teynon! I'm a little stuck on my action page: $booking_id = $_REQUEST['booking_id']; $booking_date = $_REQUEST['booking_date']; if(sizeof($_POST['Times'])) { //means if at least one check box is selected foreach($_POST['Times'] AS $start_time){ if($start_time == "07:00:00"){ $end_time = "10:00:00"; } else if($start_time == "10:00:00"){ $end_time = "13:00:00"; } else if($start_time == "13:00:00"){ $end_time = "16:00:00"; } else if($start_time == "16:00:00"){ $end_time = "19:00:00"; } $sql = "DELETE * FROM aarbookts_booking_bookings_slots WHERE booking_id=$booking_id"; $sql1 = "INSERT INTO aarbookts_booking_bookings_slots SET start_time='$start_time',end_time='$end_time',booking_date='$booking_date' WHERE booking_id=$booking_id"; } //end foreach } //end IF echo $sql; echo $sql1; this only shows one SQL DELETE and one SQL INSERT INTO I thought surely these should be in the for each loop and INSERT EACH checkbox?!

AyKay47 Posted July 22, 2011 Share Posted July 22, 2011 your insert syntax is not correct anyway... heres the correct syntax to use http://dev.mysql.com/doc/refman/5.5/en/insert.html in order to get more than one echo here. you will need to place them inside of the foreach loop.. foreach($_POST['Times'] AS $start_time){ if($start_time == "07:00:00"){ $end_time = "10:00:00"; } else if($start_time == "10:00:00"){ $end_time = "13:00:00"; } else if($start_time == "13:00:00"){ $end_time = "16:00:00"; } else if($start_time == "16:00:00"){ $end_time = "19:00:00"; } $sql = "DELETE * FROM aarbookts_booking_bookings_slots WHERE booking_id=$booking_id"; $sql1 = "INSERT INTO aarbookts_booking_bookings_slots SET start_time='$start_time',end_time='$end_time',booking_date='$booking_date' WHERE booking_id=$booking_id"; echo $sql; echo $sql1; } //end foreach } //end IF Link to comment https://forums.phpfreaks.com/topic/242573-looping-through-checkboxes-please-help/#findComment-1246269 Share on other sites More sharing options...
