Question

我有一个简单的表格，里面有复选框和多选输入。

我遇到的问题是：

多选输入仅提交最后一个选择！
只有设置了值=＆＃34;＆＃34;复选框才有效。但没有它就不应该工作？

以下是表格：

<fieldset>
    <p>Multi selection</p>
    <select name="dropdown2[]" class="select multi-select " data-placeholder="Choose an option" multiple="multiple">
        <optgroup label="Section">
            <option>Drop Down Option A</option>
            <option>Drop Down Option B</option>
        </optgroup>
        <optgroup label="Section">
            <option>Drop Down Option A</option>
            <option>Drop Down Option B</option>
        </optgroup>
    </select>
</fieldset>
<fieldset>
    <p>Optional checkboxs</p>
    <label class="checkbox">
        <input name="11" type="checkbox"><span><i></i></span>
        <p>CheckA</p>
    </label>
    <label class="checkbox">
        <input name="11" type="checkbox"><span><i></i></span>
        <p>CheckB</p>
    </label>
</fieldset>

这是PHP：

<?php
// Only start sessions if they haven't been already to prevent errors
if (empty($_SESSION)){session_start();}

// If 'data' var was received via POST from form-validation.js
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    // There's not really a need for this line with modern browsers
    ob_start();

    // Open the div around the message
    $message = "<div style=\"styling stuff\">";

    // Loop through every single post value
    foreach ($_REQUEST as $key => $value) {
        // If it's not empty
        if (!empty($value)) {
            // Change the name attributes to look a bit more human-readable
            $thisKey = str_replace("-", " ", str_replace("_", "|", $key));

            // Populate the message var
            $message .= "<strong>" . $thisKey . ":</strong> " . $value . "<br />";
        }
    }
    // Close the div around the message
    $message .= '</div>';

    // Mail variables
    $to = 'email@email.com';
    $subject = 'New Message';
    $headers = "From: email@email.com\r\n";
    $headers .= "Reply-To: email@email.com\r\n";
    $headers .= "MIME-Version: 1.0\r\n";
    $headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";

    // Attempt to send
    $sendMail = @mail($to, $subject, $message, $headers);

    // If it fails...
    if (!$sendMail) {
        // Terminate processing with error
        die("There was a problem sending the email");
    } else {
        // Terminate processing with success msg
        die("Email was sent!");
    }

    // As above, no real need for this line with modern browsers
    ob_flush();

    // Terminate
    die();
}
?>

Answer 1

如果您想通过复选框发送多个值，则应以这种方式使用它们

<input name="11[]" type="checkbox"> 
<input name="11[]" type="checkbox">

而不是

<input name="11" type="checkbox">

Answer 2

如果您需要提交多重复选框像这样使用

<input name="11[]" type="checkbox" value="someval"> 
<input name="11[]" type="checkbox" value="someval"  >

这会将复选框元素作为数组

发布

检索

$chk = $_POST['11']; // this will be array

遍历此数组，您将获得名称为11的所有已检查元素

仍然需要提供一些值来复选框才能使用

多选输入仅提交最后一个选择
