我使用的是Laravel 8框架。

使用查询从表中获取值并在复选框中显示，但是当我选择多个值时，它只显示单个值，而不显示多个值。

这是带有查询的刀片PHP代码。

<div class="row">
        <div class="col-xs-12 col-sm-12 col-md-12">
        <div class="form-group">
        <strong>Students:</strong>
        <div style="margin-top: 5px" >
        
        <?php  $conn = new mysqli('localhost', 'root', '', 'rp') or die ('Cannot connect to db');

$result = $conn->query("select users.id, users.name from users, model_has_roles where model_has_roles.model_id=users.id and model_has_roles.role_id=14;
");

echo "<html>";
echo "<body>";
while ($row = $result->fetch_assoc()) {
              unset($id, $name);
              $id = $row['id'];
              $name = $row['name']; 
              echo '<form><input type=checkbox name="student_id[]"  value="'.$id.'">'.$name.'</form>'; }

//echo "</select>";
echo "</body>";
echo "</html>";?>

他是我在控制器中的函数代码

<div class="row">
        <div class="col-xs-12 col-sm-12 col-md-12">
        <div class="form-group">
        <strong>Students:</strong>
        <div style="margin-top: 5px" >
        
        <?php  $conn = new mysqli('localhost', 'root', '', 'rp') or die ('Cannot connect to db');

$result = $conn->query("select users.id, users.name from users, model_has_roles where model_has_roles.model_id=users.id and model_has_roles.role_id=14;
");

echo "<html>";
echo "<body>";
while ($row = $result->fetch_assoc()) {
              unset($id, $name);
              $id = $row['id'];
              $name = $row['name']; 
              echo '<form><input type=checkbox name="student_id[]"  value="'.$id.'">'.$name.'</form>'; }

//echo "</select>";
echo "</body>";
echo "</html>";?>

正如您所看到的，如果我把它作为一个注释，它永远不会转到

中的前一个注释

如何从复选框中获取多个值？

顺晟科技：

dd()；终止循环并只返回应该回显结果的第一个值，而不是dd（）；它们或使用。

<div class="row">
        <div class="col-xs-12 col-sm-12 col-md-12">
        <div class="form-group">
        <strong>Students:</strong>
        <div style="margin-top: 5px" >
        
        <?php  $conn = new mysqli('localhost', 'root', '', 'rp') or die ('Cannot connect to db');

$result = $conn->query("select users.id, users.name from users, model_has_roles where model_has_roles.model_id=users.id and model_has_roles.role_id=14;
");

echo "<html>";
echo "<body>";
while ($row = $result->fetch_assoc()) {
              unset($id, $name);
              $id = $row['id'];
              $name = $row['name']; 
              echo '<form><input type=checkbox name="student_id[]"  value="'.$id.'">'.$name.'</form>'; }

//echo "</select>";
echo "</body>";
echo "</html>";?>

既然我不知道你想做什么，我就放弃第二个想法

<div class="row">
        <div class="col-xs-12 col-sm-12 col-md-12">
        <div class="form-group">
        <strong>Students:</strong>
        <div style="margin-top: 5px" >
        
        <?php  $conn = new mysqli('localhost', 'root', '', 'rp') or die ('Cannot connect to db');

$result = $conn->query("select users.id, users.name from users, model_has_roles where model_has_roles.model_id=users.id and model_has_roles.role_id=14;
");

echo "<html>";
echo "<body>";
while ($row = $result->fetch_assoc()) {
              unset($id, $name);
              $id = $row['id'];
              $name = $row['name']; 
              echo '<form><input type=checkbox name="student_id[]"  value="'.$id.'">'.$name.'</form>'; }

//echo "</select>";
echo "</body>";
echo "</html>";?>
