如何使用php获取所选文本框值

我有一个属性列表，我得到了符合我的选择标准的用户列表

我需要向所选用户发送邮件

我选中所有选项来检查每个用户

我有文本框，每个用户都可以更改租金值

我选择了某个用户，然后单击“发送我需要发送文本框中有值的邮件”

我想在表单提交代码中获取所选文本框值

在上图中，每个属性都有一个复选框，checkbob用于选中所有属性。我有一个价格文本框

当我通过选择一些属性单击“发送”时，我想发送一封邮件，告知已发布的租金值

下面是示例代码

    while($tenant = mysqli_fetch_array($result))
        {
        echo '
        <tr>

            <td>
                <a href="property.php?id='.$pro['id'].'"><img src="'.(($pro['image_1']) ? $pro['image_1'] : 'images/placeholder.png').'" alt="" width="100"></a>
            </td>

            <td><a href="#">'.$name['name'].$tenant['tenant_id'].' </a><br> '.$pro['name'].'</td>

            <td><b>'.$tenant['lease_exp'].'</b><br><i>'.$pro['ready'].'</i></td>

            <td>'.$pro['type'].'</td>

            <td><div class="price"><strong>$</strong><span>'.$tenant['rent_from'].'-'.$tenant['rent_to'].'</span></div><br><br><input type="text" name="new_rent'.$i.'" value='.$pro['rent'].' class="form-control" style="width:30%;" ></td>

            <td>
                <input type="checkbox" name="rent[]" id="rent'.$i.'" value="'.$tenant['tenant_id'].'"> Send

            </td>
        </tr>
        ';
    }

    <script>
    $(document).ready(function() {
    $('#all').change(function(){
    var ckb_status = $("#all").prop('checked');
    $('input[type="checkbox"]').prop("checked", ckb_status );
    });
    });
    </script>

    if(isset($_POST['submit'])) {
      if(!empty($_POST['rent'])) {
          print_r($_POST);
        foreach($_POST['rent'] as $check) {

            $tenant_profile = "SELECT * FROM tenant where id=".$check;
            $prof = mysqli_query($link, $tenant_profile);
            $profile = mysqli_fetch_array($prof);



            //echo $tenant_profile;
            //echo "</br>";
            //echo $pro['name'];

            echo $_POST['new_rent'];echo "</br>";

            $to      = $profile['email'];
            $subject = 'Price Change Alert';
            $header = "From: ".ADMIN_EMAIL."\r\n"; 
            $header.= "MIME-Version: 1.0\r\n"; 
            $header.= "Content-Type: text/plain; charset=utf-8\r\n"; 
            $header.= "X-Priority: 1\r\n"; 
            $message = '' ;
            $message .= "<div><p>Dear User there is a price drop for the property
            <a href='".$_SERVER['SERVER_NAME']."/property.php?id=".$pro['id']."'>".$pro['name']."</a></p>
            <p>Owner offering you ".$_POST['new_rent'].". </p>
            <p>please contact the owner for the complete details. </p>
            <p>Owner email id:#</div>";

            $mail1 = mail($to, $subject, $message, $header);

            if($mail1) { echo 'mail sent successfully'; }


        }// foreach
      } //empty checkbox check
    else  { echo "Plase Check Any Result"; }
    }//submit

$POST['new_rent']找不到任何内容，因为文本框名为new_rent$i

更好的方法是对复选框和文本框使用数组名称，并对两者使用相同的$i作为数组索引

$i = 0;
while($tenant = mysqli_fetch_array($result))
    {
    echo '
    <tr>

        <td>
            <a href="property.php?id='.$pro['id'].'"><img src="'.(($pro['image_1']) ? $pro['image_1'] : 'images/placeholder.png').'" alt="" width="100"></a>
        </td>

        <td><a href="#">'.$name['name'].$tenant['tenant_id'].' </a><br> '.$pro['name'].'</td>

        <td><b>'.$tenant['lease_exp'].'</b><br><i>'.$pro['ready'].'</i></td>

        <td>'.$pro['type'].'</td>

        <td><div class="price"><strong>$</strong><span>'.$tenant['rent_from'].'-'.$tenant['rent_to'].'</span></div><br><br><input type="text" name="new_rent['.$i.']" value='.$pro['rent'].' class="form-control" style="width:30%;" ></td>

        <td>
            <input type="checkbox" name="rent['.$i.']" id="rent'.$i.'" value="'.$tenant['tenant_id'].'"> Send

        </td>
    </tr>
    ';
    $i++;
}

然后，您可以在数组中循环并获得相应的输入

foreach ($_POST['rent'] as $i => $check) {
    $new_rent = $_POST['new_rent'][$i];
    $tenant_profile = "SELECT * FROM tenant where id=".$check;
    $prof = mysqli_query($link, $tenant_profile);
    $profile = mysqli_fetch_array($prof);



    //echo $tenant_profile;
    //echo "</br>";
    //echo $pro['name'];

    echo $_POST['new_rent'];echo "</br>";

    $to      = $profile['email'];
    $subject = 'Price Change Alert';
    $header = "From: ".ADMIN_EMAIL."\r\n"; 
    $header.= "MIME-Version: 1.0\r\n"; 
    $header.= "Content-Type: text/plain; charset=utf-8\r\n"; 
    $header.= "X-Priority: 1\r\n"; 
    $message = '' ;
    $message .= "<div><p>Dear User there is a price drop for the property
    <a href='".$_SERVER['SERVER_NAME']."/property.php?id=".$pro['id']."'>".$pro['name']."</a></p>
    <p>Owner offering you ".$new_rent.". </p>
    <p>please contact the owner for the complete details. </p>
    <p>Owner email id:#</div>";

    $mail1 = mail($to, $subject, $message, $header);

    if($mail1) { echo 'mail sent successfully'; }


}// foreach

问题是什么？你说的文本框在哪里？他用文本框代替了复选框@AedixRhinedale@AedixRhinedale复选框用于选择物业，每个物业都有一个文本框用于添加租金。我希望租金值以submitWhere的形式存在。在创建表行的while循环中，您在何处增加$I？为什么他需要获得复选框的计数？foreach会自动执行此操作。谢谢您的代码。但它不起作用。我得到的是单个值或第一个选定值，而文本框值未提交到循环。我犯了一个错误。我把$I放在字符串中，但没有注意到它是用单引号括起来的，所以变量没有展开。我将其更改为使用串联。

foreach ($_POST['rent'] as $i => $check) {
    $new_rent = $_POST['new_rent'][$i];
    $tenant_profile = "SELECT * FROM tenant where id=".$check;
    $prof = mysqli_query($link, $tenant_profile);
    $profile = mysqli_fetch_array($prof);



    //echo $tenant_profile;
    //echo "</br>";
    //echo $pro['name'];

    echo $_POST['new_rent'];echo "</br>";

    $to      = $profile['email'];
    $subject = 'Price Change Alert';
    $header = "From: ".ADMIN_EMAIL."\r\n"; 
    $header.= "MIME-Version: 1.0\r\n"; 
    $header.= "Content-Type: text/plain; charset=utf-8\r\n"; 
    $header.= "X-Priority: 1\r\n"; 
    $message = '' ;
    $message .= "<div><p>Dear User there is a price drop for the property
    <a href='".$_SERVER['SERVER_NAME']."/property.php?id=".$pro['id']."'>".$pro['name']."</a></p>
    <p>Owner offering you ".$new_rent.". </p>
    <p>please contact the owner for the complete details. </p>
    <p>Owner email id:#</div>";

    $mail1 = mail($to, $subject, $message, $header);

    if($mail1) { echo 'mail sent successfully'; }


}// foreach
