Question

我是使用交易的新手。我之前的问题是关于多个插入，如果遇到错误应该中止，而忽略的事务解决它。我的新问题是我必须知道插入是否成功，如果不成功则应显示错误。

PROFILE table
+--+----+---------+
|ID|NAME|BAL_LIMIT|
+--+----+---------+

NUMBER table
+--+----------+------+
|ID|PROFILE_ID|NUMBER|
+--+----------+------+

- 交易声明 -

START TRANSACTION;
INSERT IGNORE INTO `PROFILE` (`ID`, `NAME`, `BAL_LIMIT`) VALUES(NULL, "Name", 0);
INSERT INTO `NUMBER` (`PROFILE_ID`, `NUMBER`) VALUES(LAST_INSERT_ID() , "09123456789");
COMMIT;

- 要处理的错误 -

#1062 - Duplicate entry '09123456789' for key 'NUMBER_UNIQUE'

- PHP文件包含 -

    $vname = $_POST["iname"];
    $vbalancelimit = $_POST["ibalancelimit"];
    $vnumber = $_POST["inumber"];

$transaction = "START TRANSACTION;
INSERT IGNORE INTO `PROFILE` (`ID`, `NAME`, `BAL_LIMIT`) VALUES(NULL, \"$vname\", $vbalancelimit);
INSERT INTO `NUMBER` (`ID`, `PROFILE_ID`, `NUMBER`) VALUES(NULL, LAST_INSERT_ID(), \"$vnumber\");
COMMIT;";

$execute_transaction = mysqli_multi_query($con,$transaction) or die("Error: ".mysqli_error($connection));

if (!$execute_transaction) {
            echo mysqli_error($connection);
} else {    echo "success"; }

PHP文件总是显示成功，但有＃1062错误并且插入被忽略。

多查询交易声明问题已解决。

最终的PHP文件：

<?php 
            $vname = $_POST["iname"];
            $vbalancelimit = $_POST["ibalancelimit"];
            $vnumber = $_POST["inumber"];

            $transaction = "
                START TRANSACTION;
                INSERT IGNORE INTO `PROFILE` (`ID`, `NAME`, `BAL_LIMIT`) VALUES(NULL, \"$vname\", $vbalancelimit);
                INSERT INTO `NUMBER` (`ID`, `PROFILE_ID`, `NUMBER`) VALUES(NULL, LAST_INSERT_ID(), \"$vnumber\");
                COMMIT;";

            $aff_rows = 0;

            if(mysqli_multi_query($con,$transaction)){
                do{$aff_rows+=mysqli_affected_rows($con);
                }while(mysqli_more_results($con) && mysqli_next_result($con));
            }if($aff_rows==2){//SUCCESS
                echo "<script>swal(\"$vname\", \"New number: $vnumber\", \"success\");</script>";
            }if($aff_rows==1){//WRONG NUMBER CORRECT NAME
                echo "<script>swal(\"Duplicate entry of $vnumber\", \"Failed to add for: $vname\", \"error\");</script>";
            }if($aff_rows==0){//WRONG NAME CORRECT/WRONG NUMBER
                echo "<script>swal(\"Duplicate entry of $vname\", \"Failed to add number: $vnumber\", \"error\");</script>";}
?>
