好的，这里有几篇关于前端投递表单的帖子。我把它们都读了，这让我明白了我的意思。现在，我遇到的每一个表单都有某种形式的验证，它似乎可以检查您想要设置为必需的字段的值。我试过了，但什么都没用。我只是无法设置任何必填字段。表单的其他方面都很完美。但我希望强制执行我的必填字段（适当错误消息的奖励）。

我试着在google上四处看看，我真的不认为JS是我想要使用的。以及任何其他我似乎也无法进行的php验证。我敢肯定，我把它们都弄错了。

以下是我所拥有的：http://pastebin.com/rw4c6jZQ （应验证完整的模板行9-19）

模板的“收件人”处的我的处理脚本：

    <?php 
if( \'POST\' == $_SERVER[\'REQUEST_METHOD\'] && !empty( $_POST[\'action\'] ) &&  $_POST[\'action\'] == "new_post") { 

    // Do some minor form validation to make sure there is content 
    if (isset ($_POST[\'title\'])) { 
        $title =  $_POST[\'title\']; 
    } else { 
        echo \'Please enter the wine name\'; 
    } 
    if (isset ($_POST[\'description\'])) { 
        $description = $_POST[\'description\']; 
    } else { 
        echo \'Please enter some notes\'; 
    } 

    $tags = $_POST[\'post_tags\']; 
    $winerating = $_POST[\'winerating\']; 

    // ADD THE FORM INPUT TO $new_post ARRAY 
    $new_post = array( 
    \'post_title\'    =>   $title, 
    \'post_content\'  =>   $description, 
    \'post_category\' =>   array($_POST[\'cat\']),  // Usable for custom taxonomies too 
    \'tags_input\'    =>   array($tags), 
    \'post_status\'   =>   \'publish\',           // Choose: publish, preview, future, draft, etc. 
    \'post_type\' =>   \'post\',  //\'post\',page\' or use a custom post type if you want to 
    \'winerating\'    =>   $winerating
    ); 

    //SAVE THE POST 
    $pid = wp_insert_post($new_post); 

             //KEEPS OUR COMMA SEPARATED TAGS AS INDIVIDUAL 
    wp_set_post_tags($pid, $_POST[\'post_tags\']); 

    //REDIRECT TO THE NEW POST ON SAVE 
    $link = get_permalink( $pid ); 
    wp_redirect( $link ); 

    //ADD OUR CUSTOM FIELDS 
    add_post_meta($pid, \'rating\', $winerating, true);

    if ($_FILES) { 
        foreach ($_FILES as $file => $array) { 
        $newupload = insert_attachment($file,$pid); 
        // $newupload returns the attachment id of the file that 
        // was just uploaded. Do whatever you want with that now. 
        } 

    } // END THE IF STATEMENT FOR FILES 

} // END THE IF STATEMENT THAT STARTED THE WHOLE FORM 

//POST THE POST YO 
do_action(\'wp_insert_post\', \'wp_insert_post\');
