Question

我需要检查复选框是否已选中（必填）并且需要验证才能像其他表单字段一样执行，然后我需要在电子邮件中发布该值。

PHP表示整个表格：

<?php
if(isset($_POST['formtrigger'])):

    //config
    define('FORM_SENDTO','hello@domain.com');
    define('FORM_SUBJECTLINE','Enquiry from website');
    define('ERR_MSG_FIELD_REQUIRED','This field is required.');
    define('ERR_MSG_FIELD_INVALIDEMAIL','Please enter a valid email address.');

    //setup validation rules

        //Name
        $validation_rules['forename']['required'] = true;
        $validation_rules['surname']['required'] = true;

        //Company
        $validation_rules['company']['required'] = true;

        //Address
        $validation_rules['address']['required'] = true;

        //Tel
        $validation_rules['tel']['required'] = true;

        //Email
        $validation_rules['email']['required'] = true;
        $validation_rules['email']['valid_email'] = true;

        //Enquiry
        $validation_rules['enquiry']['required'] = true;

        //title/gender
        $validation_rules['ts1']['required'] = true;

        $validation_rules['ts2']['required'] = true;

    //validate the form
    $formerrors=0;
    foreach($_POST as $formfield_name=>$formfield_value):

        //set the entered value as a sanitised string
        $_POST_SANITISED[$formfield_name] = filter_var($formfield_value,FILTER_SANITIZE_STRING);

        //Check if required
        if($validation_rules[$formfield_name]['required']):
            if(!strlen($formfield_value)>0):
                $formerrors++;
                $fielderrors[$formfield_name][] = ERR_MSG_FIELD_REQUIRED;
            endif;
        endif;

        //Check if valid email required
        if($validation_rules[$formfield_name]['valid_email']):
            if(!filter_var($formfield_value,FILTER_VALIDATE_EMAIL)):
                $formerrors++;
                $fielderrors[$formfield_name][] = ERR_MSG_FIELD_INVALIDEMAIL;
            endif;
        endif;

    endforeach;

    //process form and send message if validation passed
    if($formerrors==0):
        $email_msg[] = "New general enquiry\n\n-----------\n";
        $email_msg[] = "Title: ".$_POST_SANITISED['ts1']."\n";
        $email_msg[] = "Gender: ".$_POST_SANITISED['ts2']."\n";
        $email_msg[] = "Forename: ".$_POST_SANITISED['forename']."\n";
        $email_msg[] = "Surname: ".$_POST_SANITISED['surname']."\n";
        $email_msg[] = "Company: ".$_POST_SANITISED['company']."\n";
        $email_msg[] = "Address: ".$_POST_SANITISED['address']."\n";
        $email_msg[] = "Telephone No.: ".$_POST_SANITISED['tel']."\n";
        $email_msg[] = "Email: ".$_POST_SANITISED['email']."\n";
        $email_msg[] = "Enquiry: ".$_POST_SANITISED['enquiry']."\n";

        $email_msg[] = "-----------\n";

        $email_msg = implode('',$email_msg);

        $email_headers = 'From: ' . $_POST_SANITISED['email'] . "\r\n" .
        'Reply-To: ' . $_POST_SANITISED['email'] . "\r\n" .
        'X-Mailer: PHP/' . phpversion();

        mail(FORM_SENDTO,FORM_SUBJECTLINE,$email_msg,$email_headers);

        header('Location: ?msgsent=1#thanks');

    endif;

endif;

function errorOutput($fieldname=''){
    global $fielderrors;
    if(count($fielderrors[$fieldname])>0):
        foreach($fielderrors[$fieldname] as $err_msg):
            $error_str .= '<div class="form-fielderror-msg">'.$err_msg.'</div>';
        endforeach;
    endif;
    return $error_str ? $error_str : false;
}

function errorClass($fieldname=''){
    global $fielderrors;
    $error_class = '';
    if(count($fielderrors[$fieldname])>0):
       $error_class = 'form-fielderror';
    endif;
    return $error_class ? $error_class : false;
}

＆GT;

这是HTML：

        <?php if($_GET['msgsent']==1): ?>

    <h1>Thanks for your enquiry. If requested, we will get in touch shortly.</h1>

    <?php else: ?>


    <div id="form-cont">

        <form action="<?=$_SERVER['PHP_SELF']?>" method="post">



            <div class="form-element">

        </form>

    </div>
    <?php endif ?>

底部有问题的复选框：

<div class="form-element">
            <label for="terms">Terms and Conditions</label>
            <input type="checkbox" name="terms" class="checkbox <?=errorClass('terms')?>" value="<?=$_POST['terms']=1?>" />
            <?=errorOutput('terms')?>
        </div>

非常感谢你的帮助！：）

Answer 1

if (isset($_POST['terms']))
{
    // checked
}

Answer 2

世界上没有办法让这些代码运行验证框的验证是你问题的最小部分

一个。您有很多Notice: Undefined index错误，例如55

B中。这不起作用，期望您的服务器支持短标记''

℃。复制太多

我只会更正您要求的验证错误，但相信我这么多错误

    $formerrors=0;
    $_POST_SANITISED = array();
    foreach($_POST as $formfield_name=>$formfield_value){
        //set the entered value as a sanitised string
        $_POST_SANITISED[$formfield_name] = filter_var($formfield_value,FILTER_SANITIZE_STRING);
        //Check if required
        if(isset($validation_rules[$formfield_name]['required']))
        {
            if(!strlen($formfield_value)>0){
                $formerrors++;
                $fielderrors[$formfield_name][] = ERR_MSG_FIELD_REQUIRED;
            }
        }
        //Check if valid email required
        if(isset($validation_rules[$formfield_name]['valid_email']))
        {
            if(!filter_var($formfield_value,FILTER_VALIDATE_EMAIL)){
                $formerrors++;
                $fielderrors[$formfield_name][] = ERR_MSG_FIELD_INVALIDEMAIL;
            }
        }
    };

    if(!isset($_POST['terms']))
    {
        $formerrors++;
        $fielderrors["terms"][] = ERR_MSG_FIELD_REQUIRED;       
    }

复选框验证和发布PHP，快速:)
