問題描述

之前有人問過類似的問題，我嘗試了所有解決方案，但由于某種原因，它們對我不起作用.

我的網站頁腳中包含一個迷你 Woocommerce 注冊字段，以便人們可以輕松注冊.電話字段是必需的，但我想為其設置最小長度以減少輸入假號碼的人數.

我將以下代碼添加到我的functions.php，(我將所有通知都包含在表單中，以便您可以更好地理解)占位符，一切正常，但我無法獲得最小長度(設置使用模式"自定義屬性)工作.

如果有人能幫我修復它，我將不勝感激.

此表格包含在我網站的頁腳中:

Similar questions have been asked before and I tried all the solutions but for some reason they won't work for me.

I have a mini Woocommerce registration field included in the footer of my site so that people can register easily. The phone field is required but I want to set a minimum length to it to reduce the number of people entering fake numbers.

I have the following codes added to my functions.php, (I'm including all the notifications to the form so that you can understand better) the placeholder and everything works but I can't get the minimum length (set using "pattern" custom attribute) to work.

If anyone can help me fix it, it'd be very much appreciated.

This form is included in the footer of my web site: wondercatspopup.com

The code I've added is:

 add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );
    function custom_override_checkout_fields( $fields )
    {        

    $fields['billing']['billing_phone']['custom_attributes'] = array( "pattern" => ".{10,10}" );
         return $fields;    
    }

And this is the rest of the functions.php:

/**
 * To add WooCommerce registration form custom fields.
 */

function text_domain_woo_reg_form_fields() {
    ?>
   <div class="formumuz" style="display:flex;"> <p class="form-row form-row-first">

Note: Your special registration form located in the footer is something different than WooCommerce checkout fields.

In your code the hook for your validating function text_domain_woo_validate_reg_form_fields() is just missing. There is also some small errors (corrected)…

The best place to check the submitted data is your validation function and you should also need to add another one for checkout too (instead of using a custom pattern for checkout phone field, that is used to format data).

So all your related code should be:

## --- FOR CHECKOUT --- ##

// Checkout billing phone validation (Checking length)
add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');
function my_custom_checkout_field_process() {
    if ( $_POST['billing_phone'] && strlen($_POST['billing_phone']) < 10 )
        wc_add_notice( __('Please type a correct phone number…', 'woocommerce'), 'error' );
}

## --- FOR CUSTOM REGISTRATION FORM --- ##

// Add custom fields to registration form.
add_action('woocommerce_register_form_start', 'text_domain_woo_reg_form_fields');
function text_domain_woo_reg_form_fields() {
    ?>
    <div class="formumuz" style="display:flex;">

            <input style="width: 130px; display: inline-block; margin-right:1px;" type="text" class="woocommerce-Input woocommerce-Input--text input-text placeholder" placeholder="?sim / Name *" type="text" class="input-text" name="billing_first_name" id="billing_first_name" value="<?php if (!empty($_POST['billing_first_name'])) esc_attr_e($_POST['billing_first_name']); ?>" />
        </p>
        <p class="form-row form-row-last">
            <label style="display:none!important;" for="billing_last_name"><?php _e('Last name', 'woocommerce'); ?><span class="required">*</span></label>

    }
}

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

Tested and works

Each time the phone number minimal length will be checked and display this alert (if needed):
