当我点击“添加Cedula Number'”这是一个按钮时,它会显示一个bootstrap模式。在里面,有一个表格。
ID中的值14是该行的ID,它来自以下代码:
<td class=" ">
<button class="btn btn-primary btn-xs" id="<?php echo $data['idPerson'];?>" data-toggle="modal" data-target="#myModal"> Add Cedula Number </button>
</td>
现在,为了传递模态中的值,我使用了以下代码:
<script>
$('#myModal').on('show.bs.modal', function (e) {
$(this).find('.modal-body').html(' <div class="form-group"><label class="col-sm-3 control-label">ID</label><div class="col-sm-9"><input type="text" value = ' + e.relatedTarget.id +' class="form-control" id="person_id" name="person_id" readonly="readonly"></div></div> <div class="form-group"> <label class="col-sm-3 control-label">Date</label><div class="col-sm-9"><input type="date" readonly="readonly" class="form-control" id="cedula_date" value="<?php echo date("Y-m-d");?>" name="cedula_date"></div></div> <div class="form-group"> <label class="col-sm-3 control-label">Cedula Number</label><div class="col-sm-9"><input type="number" class="form-control" id="cedula_number" name="cedula_number"/></div></div>' );
})
</script>
这是我的模态代码:
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">
<span aria-hidden="true">×</span>
<span class="sr-only">Close</span>
</button>
<h4 class="modal-title" id="myModalLabel">Modal title</h4>
</div>
<form id="addCedula" action="paid_cedula.php" class="form-horizontal calender" name = "addCedula" enctype="multipart/form-data" method="post" role="form">
<div class="modal-body"></div>
<div class="modal-footer" style="margin:0;">
<button type="button" class="btn btn-default"
data-dismiss="modal">Close</button>
<button id="send" type="submit" class="btn btn-success" name="addCedula">Save Record</button>
</div>
</form>
</div>
</div>
</div>
我的PHP代码是这样的:
<?php
include 'config.php';
if(isset($_POST['addCedula'])){
$id = $_POST['person_id'];
$date = $_POST['cedula_date'];
$number = $_POST['cedula_number'];
$sql = mysqli_query($conn, "UPDATE person SET dateOfCedulaPayment='$date' AND cedulaNumber='$number' WHERE idPerson='$id';");
mysqli_close($conn);
}
?>
我一直在努力寻找错误数小时。我真的无法找到原因。该值不会在数据库中更新。我哪里做错了?非常感谢您的帮助。谢谢。

您的查询不正确。这不是UPDATE的工作原理。您需要使用逗号而不是AND
逻辑运算符http://dev.mysql.com/doc/en/logical-operators.html
UPDATE person SET dateOfCedulaPayment='$date', cedulaNumber='$number' WHERE idPerson='$id';
参考:
检查查询错误会触发语法错误:
旁注:要查看您的查询(更新)是否真的成功,请使用mysqli_affected_rows()
。
如果不这样做,你可能会误报。
诺塔:
您目前的代码向SQL injection开放。使用prepared statements或PDO与prepared statements。

@ Fred的答案解决了问题(Update Query中的错误),这是我的2分
此脚本过于苛刻,无法将数据传递给模态。
<script>
$('#myModal').on('show.bs.modal', function (e) {
$(this).find('.modal-body').html(' <div class="form-group"><label class="col-sm-3 control-label">ID</label><div class="col-sm-9"><input type="text" value = ' + e.relatedTarget.id +' class="form-control" id="person_id" name="person_id" readonly="readonly"></div></div> <div class="form-group"> <label class="col-sm-3 control-label">Date</label><div class="col-sm-9"><input type="date" readonly="readonly" class="form-control" id="cedula_date" value="<?php echo date("Y-m-d");?>" name="cedula_date"></div></div> <div class="form-group"> <label class="col-sm-3 control-label">Cedula Number</label><div class="col-sm-9"><input type="number" class="form-control" id="cedula_number" name="cedula_number"/></div></div>' );
})
您只需将id="<?php echo $data['idPerson'];?>"
更改为data-id="<?php echo $data['idPerson'];?>"
,然后按照3到4行脚本执行相同的工作。
$(document).ready(function(){
$('#myModal').on('show.bs.modal', function (e) {
var id = $(e.relatedTarget).data('id');
alert(id);
$("#person_id").val(id);
});
});
