我创建了这个表，它的一部分从用户那里获取输入并将其保存在数据库中。

我试图让用户在标签中放置的数据保持显示。基本上输入形式成为输入/输出源。有关如何执行此操作的任何帮助？

switch ($selected){
    case 'University':
        $stmt = $conn->prepare("SELECT employees.afnumber,employees.name,employees.actualpost,university.brevet FROM employees,university WHERE employees.status='Employed' AND employees.afnumber=university.afnumber ORDER BY employees.afnumber DESC LIMIT :start,:end");
        $stmt->bindParam(':start', $pages->limit_start, PDO::PARAM_INT);
        $stmt->bindParam(':end', $pages->limit_end, PDO::PARAM_INT);
        $stmt->execute();
        $result = $stmt->fetchAll();
        $selectedtable  = "<form method='post' action=''>\n";
        $selectedtable .= "<table class='sortable'>\n<tr><th>Description</th><th>A</th><th>B</th><th>C</th><th>D</th></tr>\n";
        foreach($result as $row) {
            $selectedtable .= "<tr><th>Brevet</th><td><input type='text' name='Brevet1' style=' padding: 10px; margin-top:1px; border: solid 2px #c9c9c9; width:50px; height:2px;'></td><td>".$row[0]."</td><td>".$row[2]."</td><td>".$row[3]."</td></tr>
                       <tr><th>Baccalaureat/BT</th><td><input type='text' name='Baccalaureatbt' style=' padding: 10px; font-size:16px; margin-top:1px; border: solid 2px #c9c9c9; width:50px; height:2px;'></td><td>".$row[1]."</td><td>$row[2]</td><td>$row[3]</td></tr>
                       <tr><th>License/TS</th><td><input type='text' name='Licensets' style=' padding: 10px; margin-top:1px; border: solid 2px #c9c9c9; width:50px; height:2px;'></td><td>".$row[1]."</td><td>".$row[2]."</td><td>$row[3]</td></tr>
                       <tr><th>M1</th><td><input type='text' name='M1' style=' padding: 10px; margin-top:1px; border: solid 2px #c9c9c9; width:50px; height:2px;'></td><td>".$row[1]."</td><td>".$row[2]."</td><td>".$row[3]."</td></tr>
                       <tr><th>Master's Degree</th><td><input type='text' name='Mastersdegree' style=' padding: 10px; margin-top:1px; border: solid 2px #c9c9c9; width:50px; height:2px;'></td><td>".$row[1]."</td><td>".$row[2]."</td><td>".$row[3]."</td></tr>
                       <tr><th>PHD</th><td><input type='text' name='Phd' style=' padding: 10px; margin-top:1px; border: solid 2px #c9c9c9; width:50px; height:2px;'></td><td>".$row[1]."</td><td>".$row[2]."</td><td>".$row[3]."</td></tr>";

    }
    $selectedtable .= "</table>\n"; 
    $selectedtable .= "<input type='submit' name='submit' value='Submit' style='width:80px; height:30px; text-align:center; padding:0px;'>\n";
    $selectedtable .= "</form>\n";

        if(isset($_POST['submit']))
    {   $brevet1 = $_POST['Brevet1'];
        $baccalaureatbt = $_POST['Baccalaureatbt'];
        $licensets = $_POST['Licensets'];
        $m1 = $_POST['M1'];
        $mastersdegree = $_POST['Mastersdegree'];
        $phd = $_POST['Phd'];


     $sql1="SELECT Brevet1,Baccalaureatbt,Licensets,M1,Mastersdegree,Phd FROM university";
if ($result=mysqli_query($con,$sql1))
  {

  $rowcount=mysqli_num_rows($result);
  }
    if($rowcount==0)
     {
 $sql="INSERT INTO university(Brevet1,Baccalaureatbt,Licensets,M1,Mastersdegree,Phd) VALUES('$brevet1','$baccalaureatbt','$licensets','$m1','$mastersdegree','$phd')";
 $result = mysql_query($sql);
     }
     else
     {
 $sql2 = "UPDATE university SET Brevet1 = '$brevet1' , Baccalaureatbt = '$baccalaureatbt', Licensets = '$licensets', M1 = '$m1', Mastersdegree = '$mastersdegree', Phd = '$phd'";
 $result2 = mysql_query($sql2);
     }

    }


    break;

最佳答案

您可以像这样为每个输入设置一个值:

<input type='text' name='Brevet1' value="<?php echo $_POST['brevet_1']; ?>">

在三元条件下: echo (!empty($_POST['brevet_1']) ? $_POST['brevet_1'] : '');

从数据库中获取数据并像上面一样设置输入值
