Question

我正在使用类似于Dreamweaver Tutorial所示的联系表单。

除非涉及到CSS，否则我会非常好地遵循他的指示。但是，在将表单链接到我的网站后，我不断收到验证错误：

＆＃34;请输入您的留言以继续＆＃34;

即使在我输入消息后也会发生这种情况。我已经两次完成他的两部曲系列，但未能找到答案。

我的代码：

<?php

// Set email variables
$email_to = 'Matt@matthewbrianhawn.com';
$email_subject = 'Someone Contacted You on Your Site';

// Set required fields
$required_fields = array('name','email','comment');

// set error messages
$error_messages = array(
    'name' => 'Please enter a Name to proceed.',
    'email' => 'Please enter a valid Email Address to continue.',
    'comment' => 'Please enter your Message to continue.'
);

// Set form status
$form_complete = FALSE;

// configure validation array
$validation = array();

// check form submittal
if(!empty($_POST)) {
    // Sanitise POST array
    foreach($_POST as $key => $value) $_POST[$key] = remove_email_injection(trim($value));

    // Loop into required fields and make sure they match our needs
    foreach($required_fields as $field) {       
        // the field has been submitted?
        if(!array_key_exists($field, $_POST)) array_push($validation, $field);

        // check there is information in the field?
        if($_POST[$field] == '') array_push($validation, $field);

        // validate the email address supplied
        if($field == 'email') if(!validate_email_address($_POST[$field])) array_push($validation, $field);
    }

    // basic validation result
    if(count($validation) == 0) {
        // Prepare our content string
        $email_content = 'New Website Comment: ' . "\n\n";

        // simple email content
        foreach($_POST as $key => $value) {
            if($key != 'submit') $email_content .= $key . ': ' . $value . "\n";
        }

        // if validation passed ok then send the email
        mail($email_to, $email_subject, $email_content);

        // Update form switch
        $form_complete = TRUE;
    }
}

function validate_email_address($email = FALSE) {
    return (preg_match('/^[^@\s]+@([-a-z0-9]+\.)+[a-z]{2,}$/i', $email))? TRUE : FALSE;
}

function remove_email_injection($field = FALSE) {
   return (str_ireplace(array("\r", "\n", "%0a", "%0d", "Content-Type:", "bcc:","to:","cc:"), '', $field));
}

Answer 1

在您的评论的文本字段定义中

textarea name="text" class="feedback-input" id="comment" placeholder="Comment"

id将其更改为

textarea name="comment" class="feedback-input" id="comment" placeholder="Comment"

这就是为什么它认为它是空的，因为目前它被称为“文本”而不是“评论”

Answer 2

这只是因为您的$_POST变量中不存在关键的“评论”。

例如，变量$_POST的键是输入表单的名称。

尝试使用变量$error_messages

中字段的名称（'text'）替换'comment'

联系表格textarea删除提交
