Question

我正在使用Jquery Bootstrap将数据添加到MYSQL，但它不允许值为零。

这是我的剧本：

<script type="text/javascript">
jQuery(document).ready(function() {  
        $.fn.editable.defaults.mode = 'popup';
        $('.xedit').editable(); 
        $(document).on('click','.editable-submit',function(){
            var x = $(this).closest('.editable-container').prev().attr('data-id');
            var key = $(this).closest('.editable-container').prev().attr('id');
            var y = $('.input-sm').val();
            var z = $(this).closest('.editable-container').prev();
            $.ajax({
                url: "add_preds.php?id="+x+"&pred="+y+"&key="+key,
                type: 'GET',
                success: function(s){
                if(s == 'status'){
                $(z).html(y);}
                if(s == 'error') {
                alert('Error Processing your Request!');}
                },
                error: function(e){
                alert('Error Processing your Request!!');
                }
            });

        });     

});
</script>

这是add_preds.php：

$id = $mysqli->real_escape_string($_GET['id']);
$pred_org = $mysqli->real_escape_string($_GET['pred']);
$key = $mysqli->real_escape_string($_GET['key']);

//Only numbers
$pred = preg_replace('/\D/', '', $pred_org);

//Fetch user id
$qus = "SELECT id, admin FROM fxweb_users WHERE username = '".htmlentities($_SESSION['username'])."'";
$rus = mysqli_query($mysqli, $qus);
$rowus = mysqli_fetch_array($rus);
$userid = $rowus['id'];
$is_admin = $rowus['admin'];

//Check if match exists
$qm = "SELECT * FROM fxweb_predictiondata WHERE matchid = ".$id." AND userid = ".$userid."";
$rm = mysqli_query($mysqli, $qm);
$rowm = mysqli_fetch_array($rm);
$predhome = $rowm['homescore']; 
$predaway = $rowm['awayscore']; 

//Define date and time
$date = date('Y-m-d H:i:s');

if ($key == 1 && $pred) {
if ($predhome >= 0) {
//a real user posted a real reply
    if ($insert_stmt = $mysqli->prepare("UPDATE fxweb_predictiondata SET homescore=? WHERE matchid=? AND userid=?")) {    
   $insert_stmt->bind_param('sss', $pred, $id, $userid); 
   // Execute the prepared query.
   $insert_stmt->execute();
}
}
}

if ($key == 1 && !$predhome && !$predaway && $pred) {
    if ($insert_stmt = $mysqli->prepare("INSERT INTO fxweb_predictiondata (userid, matchid, predtime, homescore) VALUES (?, ?, ?, ?)")) {    
   $insert_stmt->bind_param('ssss', $userid, $id, $date, $pred); 
   // Execute the prepared query.
   $insert_stmt->execute();
}
}

if ($key == 2 && $pred) {
if ($predaway >= 0 ) {
//a real user posted a real reply
    if ($insert_stmt = $mysqli->prepare("UPDATE fxweb_predictiondata SET awayscore=? WHERE matchid=? AND userid=?")) {    
   $insert_stmt->bind_param('sss', $pred, $id, $userid); 
   // Execute the prepared query.
   $insert_stmt->execute();
}
}
}

if ($key == 2 && !$predaway && !$predhome && $pred) {
    if ($insert_stmt = $mysqli->prepare("INSERT INTO fxweb_predictiondata (userid, matchid, predtime, awayscore) VALUES (?, ?, ?, ?)")) {    
   $insert_stmt->bind_param('ssss', $userid, $id, $date, $pred); 
   // Execute the prepared query.
   $insert_stmt->execute();
}
}

//Admin enter match results
if ($key == 3 && $pred && $is_admin = 1) {
if ($predhome >= 0) {
//a real user posted a real reply
    if ($insert_stmt = $mysqli->prepare("UPDATE fxweb_matches SET homescore=? WHERE id=?")) {    
   $insert_stmt->bind_param('ss', $pred, $id); 
   // Execute the prepared query.
   $insert_stmt->execute();
}
}
}



if ($key == 4 && $pred && $is_admin = 1) {
if ($predaway >= 0 ) {
//a real user posted a real reply
    if ($insert_stmt = $mysqli->prepare("UPDATE fxweb_matches SET awayscore=? WHERE id=?")) {    
   $insert_stmt->bind_param('ss', $pred, $id); 
   // Execute the prepared query.
   $insert_stmt->execute();
}
}
}

该脚本运行良好，直到我尝试向输入添加“0”，它不允许它并抛出错误警告！

有人知道解决这个问题吗？

我找到了解决方案：

我在add_preds.php文件中有一个“if”语句，用于搜索预测值：

if ($key == 1 && $pred)

但是如果在输入字段中输入零（0），似乎jquery / Bootstrap没有传递值，因此数据库查询不成功！

我只是从if语句中删除了预测值：

if ($key == 1)

然后它运作正常！

我还在jquery脚本中将“GET”更改为“POST”，如评论中所述。

Jquery Bootstrap不允许零作为值
