php - 使用 execute($array) 插入时出现错误

Question

我有一张桌子

percentile      int(3)  No           
FoSW            int(3)  Yes     NULL     
dfLR            int(3)  Yes     NULL     
FoA             int(3)  Yes     NULL     
SoG             int(3)  Yes     NULL     
RST             int(3)  Yes     NULL     
SSW             int(3)  Yes     NULL    
total           int(3)  No  

和一个数组：

Array
(
    [percentile] => 99
    [FoSW] => 125
    [DfLR] => 110
    [FoA] => 60
    [SoG] => 120
    [RST] => 40
    [SSW] => 45
    [total] => 500
)

而且这段代码由于某种原因不起作用...... Catch 不会引发错误。只是我的 if 语句回显错误...

if ($_POST['percent']=='add'){
    try{
        $post = $_POST;
        unset($post['percent']);

        $sth = $dbh->prepare("INSERT INTO percentiles (percentile, FoSW, dfLR, FoA, SoG, RST, SSW, total) VALUES (?,?,?,?,?,?,?,?)");

        if ($sth->execute($post)){
            echo 'done<br/>';
        }

        else echo 'error';
    }

    catch(PDOException $e){
        echo 'error'.$e;
    }
}

您的数组与操作$post所需的八个值匹配INSERT，但该数组应按整数索引，而不是关联数组/字典。

Array
(
    [percentile] => 99
    [FoSW] => 125
    [DfLR] => 110
    [FoA] => 60
    [SoG] => 120
    [RST] => 40
    [SSW] => 45
    [total] => 500
)

如果您按以下方式更改prepare()调用，则上述数组将起作用：

$sth = $dbh->prepare("INSERT INTO percentiles 
        (percentile, FoSW, 
        dfLR, FoA, 
        SoG, RST, 
        SSW, total) 
    VALUES
        (:percentile, :FoSW, 
        :DfLR, :FoA, 
        :SoG, :RST, 
        :SSW, :total)");
