Question

我有属性列表，我得到符合我的选择标准的用户列表。

我需要向选定的用户发送邮件。

我检查所有选项以检查每个用户。

我有每个用户的文本框来更改租金值。

我选择了一些用户，然后点击发送，我需要在文本框中发送有价值的邮件。

我想获取所选文本框值以形成提交代码。

在上图中，每个属性都有一个复选框，checkbob用于检查所有属性。我有价格的文字框。

当我点击发送时，通过选择一些属性我想发送邮件发布的租金值

以下是示例代码。

    while($tenant = mysqli_fetch_array($result))
        {
        echo '

        }// foreach

    }//submit

Answer 1

Count how many checkbox are getting checked. 

$rent=$_POST['rent']; // Changes Done
$SelectedCheckbox=sizeof($rent); // Changes Done
for($i=0;$i<$SelectedCheckbox;$i++)

$POST['new_rent']找不到任何内容，因为文本框的名称为new_rent$i。

更好的方法是使用复选框和文本框的数组名称，并使用相同的$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++;
}

然后你可以循环遍历数组并获得相应的输入。

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
