Question

我试图根据从我的数据库中检索到的结果给每个模态表单一个唯一的id，以便将不同的数据传递到php表单处理器。我有一个表放在一个表格中，每个行的唯一值为“mapid”

但是，每行还有一个模态，我已经放置了另一个表单，但我得到的唯一值是sql查询的第一行。请帮忙。

    $sql = "SELECT mapid, location, DATE_FORMAT(date,'%d/%m/%y') AS date, status FROM maps ORDER BY status DESC, date DESC ";    
$result = $mysqli->query($sql);


if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {

echo
'
<form action="map.php" method="post">

    <tr>

        <td> '. $row["mapid"].' </td>

        <td> '. $row["location"].' </td>

        <td> ' . ($row["status"]=='0' ? 'Last Done' : (($row["status"]=='1') ? 'Started' : 'Done')).' </td>

        <td> '.$row["date"].' </td>

        <td> ' . 
        (($row["status"]=='0') ?
            '<input type="hidden" name="mapid" value="'. $row["mapid"].'"/>
            <input type="hidden" name="start" value="start"/>
                <button class="btn btn-primary" name="getmap" type="submit">Start</button>'

        : (($row["status"]=='1') ? 
            '<input type="hidden" name="mapid" value="'. $row["mapid"].'"/>
            <input type="hidden" name="resume" value="resume"/>
            <button class="btn btn-danger" type="submit" name="getmap" value="'. $row["mapid"].'">Resume</button>'

        : (($row["status"]=='2') ?
           '<input type="hidden" name="mapid" value="'. $row["mapid"].'"/>
            <input type="hidden" name="process" value="process"/>
                <button class="btn btn-primary" type="submit" name="getmap">Process</button>' 
        : ''))) . '

        </td>
</form>


        <td>
            <button class="btn btn-primary" data-toggle="modal" data-target="#assign['. $row["mapid"].']">Assign</button>
        </td>

        <div class="modal fade" id="assign['. $row["mapid"].']" tabindex="-1" role="dialog" aria-labelledby="assignLabel" aria-hidden="true">

只需添加['即可为模态添加唯一ID。 $ row [“mapid”]。']旁边的#assign。

 <td>
            <button class="btn btn-primary" data-toggle="modal" data-target="#assign['. $row["mapid"].']" value"">Assign</button>
        </td>
        
        
        
        <div class="modal fade" id="assign['. $row["mapid"].']" tabindex="-1" role="dialog" aria-labelledby="assignLabel" aria-hidden="true">
        <div class="modal-dialog" role="document">
            <div class="modal-content">
