Wordpress自定义短代码表单无法发布到同一页面

提问于

我将表单数据发布到同一页面以在Wordpress中处理它时遇到问题 . 我创建了一个名为[lwCSForm]的短代码，它可以工作并在页面上添加已添加的表单 . 问题是，当我按提交页面时，不会注意到$ _POST ['submit']变量，而我的代码无法处理数据 .

I have tested to use these actions in the form:

  • action="php echo $_SERVER['PHP_SELF']" （我无法让php标签在这里工作）

  • action="php echo $post->post_title" （我无法让php标签在这里工作）

  • 甚至直接写页面名称： action="about"

This is the function to display the form through shortcode on a page:

function DisplayCustomSettingsForm_shortcode() {
global $post;

if( !is_user_logged_in() ){
    echo '<div class="lwCSForm-notloggedin">
            <p> Please login to view the content! </p>
          </div>';
    return;
}

if( isset( $_POST['submit'] ) )
{
    echo "The submit button is pressed and has data";
    /* Code to update customers settings, like avatar, email, username */

} else {
$phpself = $post->post_title; // get the current page

  ?>

        <!-- LwCSForm Plugin-->
        <section id="lwCSForm-wrapper">
            <form name="lwCSForm" id="lwCSForm" method="post" action="<?php $phpself ?>" autocomplete="on">
                Name: <input type="text" name="realname" placeholder="Your Name" >
                Sitename: <input type="text" name="username" placeholder="Username" >
                E-mail: <input type="text" name="email" placeholder="E-mail" >
                Avatar: <input type="text" name="avatar" placeholder="Avatar" >
                <input type="submit" >
            </form>
        </section>
        <!-- END LwCSForm Plugin-->
    
 <?php
 }
}
add_shortcode( 'lwCSForm', 'DisplayCustomSettingsForm_shortcode');

为什么wordpress不会处理这些信息？并再次免责声明 . 我无法在这里打印php标签，但它们在源代码中 .

    我发现你可以编写如下所示的函数，并且更容易进行表单验证和数据处理 . 请注意 action="" 正在使用Wordpress的"the_permalink()"函数 . 这使我们能够在相同的函数中编写所有已发布数据的验证和处理，而不是将其单独挂钩到Wordpress的'INIT'函数 .

    if( isset( $_POST[ 'lwCSFormSubmit' ] ) )
{

}

    以下新功能：

    function DisplayCustomSettingsForm_shortcode() {
    global $post;

    if( !is_user_logged_in() ){
        echo '<div class="lwCSForm-notloggedin">
                <p> Please login to view the content! </p>
              </div>';
        return;
    }

    if( isset( $_POST['lwCSFormSubmit'] ) )
    {
        echo "The submit button is pressed and has data";
        var_dump($_POST);
    } 
    ?>
         <!-- LwCSForm Plugin-->
         
    
                <section id="lwCSForm-wrapper">
                    <form name="lwCSForm" id="lwCSForm" method="post" action="<?php the_permalink(); ?>" autocomplete="on">
                        Name: <input type="text" name="realname" placeholder="Your Name" >

                        Sitename: <input type="text" name="username" placeholder="Username" >

                        Email: <input type="text" name="email" placeholder="E-mail" >

                        Avatar: <input type="text" name="avatar" placeholder="Avatar" >

                        <input type="submit" name="lwCSFormSubmit">
                    </form>
                </section>
         
     
         <!-- END LwCSForm Plugin-->
<?php
}
add_shortcode( 'lwCSForm', 'DisplayCustomSettingsForm_shortcode');

    将您的代码更改为

    function DisplayCustomSettingsForm_shortcode() {
    global $post;

    if( !is_user_logged_in() ){
        echo '<div class="lwCSForm-notloggedin">
                <p> Please login to view the content! </p>
              </div>';
        return;
    }


    ?>
    
        <!-- LwCSForm Plugin-->
        <section id="lwCSForm-wrapper">
            <form name="lwCSForm" id="lwCSForm" method="post" action="" autocomplete="on">
                Name: <input type="text" name="realname" placeholder="Your Name" >
                Sitename: <input type="text" name="username" placeholder="Username" >
                E-mail: <input type="text" name="email" placeholder="E-mail" >
                Avatar: <input type="text" name="avatar" placeholder="Avatar" >
                <input name='WCSPostSubmitButton' type="submit" >
            </form>
        </section>
        <!-- END LwCSForm Plugin-->
    
     <?php

}
add_shortcode( 'lwCSForm', 'DisplayCustomSettingsForm_shortcode');

add_action( 'init', 'WCSGetPostData' );
function WCSGetPostData() {
    if ( isset( $_POST['WCSPostSubmitButton'] ) ) {
        // dump out the POST data
        var_dump($_POST);

    }
}

    我已经将POST处理移动到 init 钩子，并且我已经为您的表单命名，因此我们可以通过$ _POST数组识别它 .
