Pls Help Me With This Php Code by lillylove2(f): 7:50pm On Jan 21, 2016 |
Hi NL Programmers, pls this php code is running me mad. I really need your help. In my database Table, I have 2 rows. The first is named 'User' and d second is named 'amount'. There are two records in the table: Record 1: User=dami24, Amount=120 Record 2: User=dami24, Amount=30 What im trying to do is to "Select Amount From Table Where user=dami24" After selecting the amounts, i want to add them together, so the final result should be 150 (120+30). l've tried all i could without the desired result. Array_sum, implode/explode, mysql-fetch_array, yet no result pls help me out |

lillylove2:Try this <?php $query = "SELECT * FROM `table` WHERE `User`='dami24'"; $result = mysqli_query ($link, $query) ; $row = mysqli_fetch_assoc($result) ; $row_cnt = $result->num_rows; $sum = 0; $cnt = 0; //try 1 if 0 doesnt work properly while ($cnt < $row_cnt) { $row = mysqli_fetch_assoc($result) ; $amount = $row['amount'] ; $sum = $sum + $amount; $cnt++; } ? > |

lol.. you can sum it up right from your SQL statement SELECT SUM(column_name) FROM table_name WHERE condition; Select sum(Amount) From Table Where user=dami24; 1 Like |

Re: Pls Help Me With This Php Code by losprince(m): 10:31pm On Jan 21, 2016 |
lillylove2: select sum(amount) as total from table where user = dami24 echo $row['total']; show your own code |
Re: Pls Help Me With This Php Code by hollyfat(m): 10:34pm On Jan 21, 2016 |
lillylove2: $sql = mysqli_query("SELECT SUM(Amount) as total FROM table where user='dami24'" or die(mysqli_error()); $rs = mysqli_fetch_assoc($sql); $sum = $rs['total']; echo $sum; |

Thanks everybody for taking your time out to help me. Its finally working. |
Re: Pls Help Me With This Php Code by lillylove2(f): 10:46pm On Jan 21, 2016 |
hollyfat: Does this also work on regular mysql (not mysqli) ? I tried it, it didnt work |
Re: Pls Help Me With This Php Code by hollyfat(m): 11:04pm On Jan 21, 2016 |
lillylove2:. You can use mysql if mysqli didn't work. |
Re: Pls Help Me With This Php Code by lillylove2(f): 11:17pm On Jan 21, 2016 |
My God! Its multiplication im looking for not addition. Im totally unserious! Please help me out |
Re: Pls Help Me With This Php Code by hollyfat(m): 11:31pm On Jan 21, 2016 |
lillylove2:$sql = mysql_query("select amount from table where user='dami24'" or die(mysql_error()); $product = 1; //initialize your product while($rs = mysql_fetch_assoc($sql)){ $amt = $rs['amount']; //get the amount $product *= $amt; } echo $product; |
Re: Pls Help Me With This Php Code by lillylove2(f): 11:53pm On Jan 21, 2016 |
hollyfat: My God It Worked! Im really, really grateful. I can't thank you enough. I spent up to 3 hours before i was finally able to make the other one work, only to realize it was multiplication i was seeking, not addition. I had even given up, and accepted my fate that i will never be a programmer, only for me to try out ur code and it worked! Thanks very much. |

lillylove2:You are welcome |
Re: Pls Help Me With This Php Code by A7(m): 9:35pm On Jan 22, 2016 |
lillylove2: This is how to make array_sum work. Set a variable holding an empty array: $loop_results = array(); Query your db: $sql = ("SELECT `amount` FROM `table` WHERE `user`='".dami24."'" ) ; $query = mysqli_query($con, $sql); If(mysqli_num_rows($query) > 0{ while($rows = mysqli_fetch_assoc($query){ $loop_results[] = $rows['amount']; } } If(empty($loop_results) == false){ $amount_sum = array_sum($loop_results); echo $amount_sum; } |
Re: Pls Help Me With This Php Code by A7(m): 9:49pm On Jan 22, 2016 |
lillylove2: In that case replace array_sum with array_product. |
