Question

我有一个带有图像的表单，带有复选框的图像文件名和带有数量的字段文本（这是管理员在wordpress文件夹上传图像时动态创建的）用户选中复选框并写入数量，我希望将该信息发送到电子邮件。我做到了这一点，但它只有在我点击所有复选框时才有效，如果没有选中其中一个复选框，它会发送包含空信息的电子邮件。

这是我认为问题所在代码的一部分：

    // if the submit button is clicked, send the email
       if ( isset( $_POST['cf-submitted'] ) ) {
        $result ="";
        $myQuantity = $_POST["quantity"];
        $myFile = $_POST["fileName"];   
        //Combine both filename and quantity arrays      
        $values = array_combine($myFile, $myQuantity);

        if(!empty($_POST["fileName"])){
            foreach($values as $key => $value){
                $result .= "$key - Quantity: $value <br/>";
            }
        }

... 任何帮助将不胜感激。

更新：这是整个表格以防万一：

    echo '<div class="images-form"><form action="' . esc_url( $_SERVER['REQUEST_URI'] ) . '" method="post">';
        foreach($images as $image) {
            echo '<div class="thumb"><img src="';
            echo $uploads['baseurl'].'/'.$a['folder_name'].'/'.$image;
            echo '" alt="" /><br/>';
            $fileName = basename($path.'/'.$image);
            echo $fileName;
            echo '&nbsp;&nbsp;<input name="fileName[]" type ="checkbox" value="'.$fileName.'" /><br/>';
            echo 'Quantity: <input name="quantity[]" type="text" value="" size="5" /></div>';
        }

    echo  '<div class="send-form"><input type="submit" name="cf-submitted" value="Send email"/></div></form></div>';


  // if the submit button is clicked, send the email
    if ( isset( $_POST['cf-submitted'] ) ) {
        $result ="";
        $myQuantity = $_POST["quantity"];
        $myFile = $_POST["fileName"];   
        //Combine both arrays      
        $values = array_combine($myFile, $myQuantity);

        if(!empty($_POST["fileName"])){
            foreach($values as $key => $value){
                $result .= "$key - Quantity: $value <br/>";
            }
        }

        // to get wordpress user name and last name
        global $current_user;
        get_currentuserinfo();
        $userName = $current_user->user_firstname;
        $userLastName = $current_user->user_lastname ;

        $to = get_option( 'admin_email' );// get the blog administrator's email address
        $email = $current_user->user_email;
        $headers = "From: $email" . "\r\n";
        $headers .= "MIME-Version: 1.0\r\n";
        $headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
        $subject = "Print request";
        $message = "<html><body>";
        $message .= $userName." ".$userLastName." wants to print the following file(s): <br/>".$result;
        $message .= "</body></html>";


        // If email has been process for sending, display a success message
        if ( wp_mail( $to, $subject, $message, $headers ) ) {
            echo '<div>';
            echo '<p>Thanks for contacting me, expect a response soon.</p>';
            echo '</div>';
        } else {
            echo 'An unexpected error occurred';
        }
    }

当浏览器提交表单时，只会将选中的复选框传递给服务器。另一方面，即使文本框为空，也始终传递。 PHP仅使用$ _POST [＆＃39; fileName＆＃39;]的复选框和$ _POST [＆＃39;数量＆＃39;]中所有数量框的数组创建数组。

如果选择的复选框少于所有复选框，则$ myQuantity将具有与$ myFile不同的元素数。

导致问题。如果每个数组中的元素数量不相等，则Array_combine返回false。

对此的一个简单解决方案是索引输入框并消除array_combine。

$index=0;
foreach($images as $image) {
    $index++; 
    echo '<div class="thumb"><img src="';
    echo $uploads['baseurl'].'/'.$a['folder_name'].'/'.$image;
    echo '" alt="" /><br/>';
    $fileName = basename($path.'/'.$image);
    echo $fileName;

    // use $index between the [] of the field name.  PHP will use it as the key value when it creates the array. 
    echo '&nbsp;&nbsp;<input name="fileName['. $index .']" type ="checkbox" value="'.$fileName.'" /><br/>';
    echo 'Quantity: <input name="quantity['. $index .']" type="text" value="" size="5" /></div>';
}

现在您收到$ _POST [＆＃39; filename＆＃39;]的索引数组。

$result ="";
$myQuantity = $_POST["quantity"];
$myFile = $_POST["fileName"];   
// eliminate the array_combine.  

if(!empty($_POST["fileName"])){

    foreach( $myFile as $key => $value){
        // key will now be the $index value from the form generation. 
        // $value will be the file name.  
        // The index will match the $_POST['quantity'] array allowing 
        // simple lookup by key value.
        $result .= "$value- Quantity: ". $myQuantity[$key] ."<br/>";
    }
}
