问题描述

我是 wordpress 和 php 的新手，我在我的 wordpress 网站上使用了联系表 7.因为我需要验证电子邮件地址，阻止所有免费域，例如 gmail、yahoo 等，我需要使用国家/地区代码验证印度电话号码.

I am new to wordpress and php, I'm using contact form 7 in my wordpress website. In that I need to validate the email address, block all free domains like gmail, yahoo,etc., I need to validate Indian phone number with country code.

我有 4 种类型的联系表单，但我只需要对一种表单进行此自定义验证.我用谷歌搜索并找到了 this 但它是不工作.有人请帮我解决这个问题.

I had 4 types of contact form but I need this custom validation for only one form. I googled and found this but it is not working. Someone please help me with this issue.

谢谢.

推荐答案

将以下代码添加到您的主题的functions.php文件中.

Add following code to your theme's functions.php file.

    // Add custom validation for CF7 form fields
    function is_company_email($email){ // Check against list of common public email providers & return true if the email provided *doesn't* match one of them
            if(
                    preg_match('/@gmail.com/i', $email) ||
                    preg_match('/@hotmail.com/i', $email) ||
                    preg_match('/@live.com/i', $email) ||
                    preg_match('/@msn.com/i', $email) ||
                    preg_match('/@aol.com/i', $email) ||
                    preg_match('/@yahoo.com/i', $email) ||
                    preg_match('/@inbox.com/i', $email) ||
                    preg_match('/@gmx.com/i', $email) ||
                    preg_match('/@me.com/i', $email)
            ){
                    return false; // It's a publicly available email address
            }else{
                    return true; // It's probably a company email address
            }
    }
    function your_validation_filter_func($result,$tag){
            $type = $tag['type'];
            $name = $tag['name'];
            if('yourid' == $type){ // Only apply to fields with the form field name of "company-email"
                    $the_value = $_POST[$name];
                    if(!is_company_email($the_value)){ // Isn't a company email address (it matched the list of free email providers)
                            $result['valid'] = false;
                            $result['reason'][$name] = 'You need to provide an email address that isn\'t hosted by a free provider.<br />Please contact us directly if this isn\'t possible.';
                    }
            }
            return $result;
    }
   add_filter( 'wpcf7_validate_text', 'your_validation_filter_func', 10, 2 ); // Email field or contact number field
   add_filter( 'wpcf7_validate_text*', 'your_validation_filter_func', 10, 2 ); // Req. Email field or contact number

你可以通过上面的代码实现你想要的结果.

You can achieve your desired result by the above code.

注意:我只验证了电子邮件.您可以像我对电子邮件所做的一样对联系人执行相同的操作.

NOTE: I have validated only Email.You can do same for contact like I did for Email.

回答第二个问题:

现在，正如您所提到的，您只希望它用于一种形式，那么您可以执行以下操作:

Now as you have mentioned that you want it for only one form then you can do something like this:

wpcf7_add_shortcode( 'yourid', 'wpcf7_text_shortcode_handler', true );

然后，在表单中使用这样的标签:

Then, use a tag like this inside the form:

[yourid your-id-number-field]

如果您想了解标记语法，请浏览此页面.
