$qry2="INSERT INTO `c_n_discussion`
              (`TitleOfDes`, `TopicDec`, `DecImg`) 
           VALUES ('$TitleOfDes','$TopicDec','$DesImg')";

删除您不想要的字段。

enter image description here可能是您在表格中使用的字段“检查”字段。它不会执行您的查询，因为它是预定义的约束。

 $qry2="INSERT INTO `c_n_discussion`
          (`TitleOfDes`, `TopicDec`, `DecImg`, `category`, 
           `visiblity`, `PostAs`, `check`) 
       VALUES ('$TitleOfDes','$TopicDec','$DesImg',
               '$category','$visiblity','$PostAs','$check')";

<?php
if(isset($_POST["PostThisNow"])){
    $TitleOfDes = mysqli_real_escape_string($_POST['TitleOfDes']);
    $TopicDec = mysqli_real_escape_string($_POST['TopicDec']);
    $DesImg = mysqli_real_escape_string($_POST['DesImg']);
    $category = mysqli_real_escape_string($_POST['category']);
    $visiblity = mysqli_real_escape_string($_POST['visiblity']);
    $PostAs = mysqli_real_escape_string($_POST['PostAs']);
    $check = mysqli_real_escape_string($_POST['check']);



    $qry2="INSERT INTO c_n_discussion
              (TitleOfDes, TopicDec, DecImg, category, 
               visiblity, PostAs, check) 
           VALUES ('".$TitleOfDes."','".$TopicDec."','".$DesImg."',
                   '".$category."','".$visiblity."','".$PostAs."','".$check."')";

    if(mysqli_query($qry2)){
        echo "Records added successfully.";
    } else{
        echo "ERROR Could not able to execute $qry2. " . mysqli_error($con);
    }
}
?>
