使用PHP編寫的MYSQL插入語句

Question

我試圖使用下面的php預處理語句在mysql表中插入一行，但代碼總是傳遞語句並移動到echo“failed”。 以下代碼中缺少什么？

（我的數據庫有額外的列，但我沒有添加它，因為我不想在里面插入值（其中一列是自動增量））

<?php
    $ActivityDate = $_POST["ActivitytDate"];
    $CoreSite = $_POST["CoreSite"];
    $ActionAuditor = $_POST["ActionAuditor"];
    $DCOSPOC = $_POST["DCOSPOC"];

    if($stmt = $mysqli->prepare("Insert INTO DCO_Database (ActivityDate, CoreSite, ActionAuditor, DCOSPOC) Where (ActivityDate=? AND CoreSite=? AND ActionAuditor=? AND DCOSPOC=?)"))
    {
        $stmt->bind_param("ssss", $ActivityDate, $CoreSite, $ActionAuditor, $DCOSPOC);
        $stmt->execute();
        $stmt->close();
    }
    else{
        echo ("Failed");
        $mysqli->close();    
    }
?>

我已編輯代碼以使用值，而不是回顯Failed但回顯成功..但仍然沒有向數據庫添加值

<?php
$ActivityDate = $_POST["ActivitytDate"];
$CoreSite = $_POST["CoreSite"];
$ActionAuditor = $_POST["ActionAuditor"];
$DCOSPOC = $_POST["DCOSPOC"];
$AreaOwner = $_POST["AreaOwner"];
$ActionImplementer = $_POST["ActionImplementer"];
$ActionOwner = $_POST["ActionOwner"];
$MailSubject = $_POST["MailSubject"];
$ActionType = $_POST["ActionType"];
$RequestType = $_POST["RequestType"];
$RequestNumber = $_POST["RequestNumber"];
$OpenTime = $_POST["OpenTime"];
$CloseTime = $_POST["CloseTime"];
$ActionResult = $_POST["ActionResult"];
$Violation = $_POST["Violation"];
$ActionDetails = $_POST["ActionDetails"];
$Snags = $_POST["Snags"];
$SnagDesc = $_POST["SnagDesc"];
$Layout = $_POST["Layout"];
$LayoutDesc = $_POST["LayoutDesc"];
$CabinetLocation = $_POST["CabinetLocation"];
$Mapping = $_POST["Mapping"];
$MappingDesc = $_POST["MappingDesc"];
$Notes = $_POST["Notes"];

if($stmt = $mysqli->prepare("Insert INTO DCO_Database (ActivityDate, CoreSite, ActionAuditor, DCOSPOC, AreaOwner, ActionImplementer, ActionOwner, MailSubject, ActionType, RequestType, RequestNumber, OpenTime, CloseTime, ActionResult, Violation, ActionDetails, Snags, SnagDesc, Layout, LayoutDesc, CabinetLocation, Mapping, MappingDesc, Notes) values (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)"))
{
$stmt->bind_param("ssssssssssssssssssssssss", $ActivityDate, $CoreSite, $ActionAuditor, $DCOSPOC, $AreaOwner, $ActionImplementer, $ActionOwner, $MailSubject, $ActionType, $RequestType, $RequestNumber, $OpenTime, $CloseTime, $ActionResult, $Violation, $ActionDetails, $Snags, $SnagDesc, $Layout, $LayoutDesc, $CabinetLocation, $Mapping, $MappingDesc, $Notes);
$stmt->execute();
$stmt->close();
}
else{
echo ("Failed");
$mysqli->close();    
}
echo ("Successful");
?>

Answer 1

//認為你應該這樣做，insert語句只允許在使用select語句時使用where子句，

<?php
$ActivityDate = $_POST["ActivitytDate"];
$CoreSite = $_POST["CoreSite"];
$ActionAuditor = $_POST["ActionAuditor"];
$DCOSPOC = $_POST["DCOSPOC"];

if($stmt = $mysqli->prepare("Insert INTO DCO_Database (ActivityDate, CoreSite, ActionAuditor, DCOSPOC) values (?,?,?,?)");
{
$stmt->bind_param("ssss", $ActivityDate, $CoreSite, $ActionAuditor, $DCOSPOC);
$stmt->execute();
$stmt->close();
}
else{
echo ("Failed");
$mysqli->close();    
}
?>

Answer 2

你必須使用

值

在您的查詢中。 並刪除

和

來自查詢。 請檢查以下代碼。

if($stmt = $mysqli->prepare("Insert INTO DCO_Database (ActivityDate, CoreSite, ActionAuditor, DCOSPOC) values (?,?,?,?)"))
{
$stmt->bind_param("ssss", $ActivityDate, $CoreSite, $ActionAuditor, $DCOSPOC);
$stmt->execute();
$stmt->close();
}
else{
echo ("Failed");
$mysqli->close();    
}

請注意，用於更新的位置。 所以要插入使用查詢如下：

INSERT INTO table_name (column1,column2,column3,...) VALUES (value1,value2,value3,...);

Answer 3

使用價值 insted的， 其中

<?php
 $ActivityDate = $_POST["ActivitytDate"];
 $CoreSite = $_POST["CoreSite"];
 $ActionAuditor = $_POST["ActionAuditor"];
  $DCOSPOC = $_POST["DCOSPOC"];

  if($stmt = $mysqli->prepare("Insert INTO DCO_Database (ActivityDate,  CoreSite, ActionAuditor, DCOSPOC) values(?,?,?,?)"))
  {

 $stmt->bind_param("ssss", $ActivityDate, $CoreSite, $ActionAuditor, $DCOSPOC);
 $stmt->execute();
 $stmt->close();

 }
 else{
   echo ("Failed");
   $mysqli->close();    
 }
