我有一个 Wordpress 前端表单，可以直接从我的主题发布/草稿帖子：-

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

    // Do some minor form validation to make sure there is content
    $title = $_POST["title"];
    if(!empty($_POST['middle'])) {
    $description = 'a sentence ' . $_POST['middle'] . ' with something in the MIDDLE. a sentence ' . $_POST['end'] . ' with something in the END.';
    }
    $tags = $_POST["tags"];
    $post_cat = $_POST['cat'];

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

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

    //REDIRECT TO THE NEW POST ON SAVE
    $link = get_permalink( $pid );
    wp_redirect( '/post-submitted-draft' );

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

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

?>

我有一个简单的 php 表单，它具有以下功能：-

<?php
if(!empty($_POST['middle'])) {
   echo "a sentence".$_POST['middle']." with something in the MIDDLE.";
}

if(!empty($_POST['end'])) {
   echo "a sentence".$_POST['end']." with something in the END.";
}
?>

我想将它包含在表单中，我使用以下方法完成了它： -

if(!empty($_POST['middle'])) {
$description = 'a sentence ' . $_POST['middle'] . ' with something in the MIDDLE. a sentence ' . $_POST['end'] . ' with something in the END.';

但是如果'middle'的字段为空，它将忽略$description的整个值，如果'middle'的字段为空，我希望它只忽略第一句并显示具有字段'end的第二句' IE

'a sentence ' . $_POST['end'] . ' with something in the END.';

如何让它像这样工作？

改变 ：

if(!empty($_POST['middle'])) {
$description = 'a sentence ' . $_POST['middle'] . ' with something in the MIDDLE. a sentence ' . $_POST['end'] . ' with something in the END.';

到 ：

$description = (!empty($_POST['middle']))? 'a sentence ' . $_POST['middle'] . ' with something in the MIDDLE.': '' ;
$description .= (!empty($_POST['end']))? 'a sentence ' . $_POST['end'] . ' with something in the END.': '' ;

遵循下面这样的方法将使整个事情变得更好，更有意义。基本上，将描述变量设置为第一句并添加第二位（如果存在）。

if(!empty($_POST['middle'])) {
   $description = "a sentence".$_POST['middle']." with something in the MIDDLE.";
}

if(!empty($_POST['end'])) {
   $description .= "a sentence".$_POST['end']." with something in the END.";
}

if(isset($description)) {
// do something with description
}

另外，请考虑根据您的用途转义字符串。
