我正在为Wordpress构建CRM主题。所以我在前端发布、编辑和删除帖子。我想我正在寻找一种解决所有问题的好方法。但有一个失败。在索引处有一个“编辑”和“删除”按钮。如果我点击“编辑”，我将进入一个表单。我可以在那里更改post\\u标签。更改将被保存，但单个单词不会分开。输入字段中的所有单词都是一个巨大的标记-我可以在侧栏的小部件中看到它。但我用分隔符。。。如果您有2分钟：

在这里（index.php中），我可以删除一篇帖子：

if( \'POST\' == $_SERVER[\'REQUEST_METHOD\'] ) {
   set_query_var( \'postid1\', $_POST[\'postid\'] );     /*  set the "postid" value from the delete button of the post we choose to delete into "postid1" */
   wp_delete_post( get_query_var( \'postid1\'), true );  /* delete the post we choosed */
};
get_header(); ?>

在索引的循环中，您可以找到以下代码段。第一个表单用于编辑，第二个表单用于删除：

<form class="edit" action="<?php echo esc_url( home_url( \'/\' ) ); ?>editieren-formular/" method="post">
    <input type="hidden" name="postid" value="<?php the_ID(); ?>" /> <?php /* get the post ID into "postid" and later pass it to "editieren-formular.php" */ ?>
    <input type="submit" value="Edit" />
</form>
<form class="delete" action="" method="post">
    <input type="hidden" name="postid" value="<?php the_ID(); ?>" /> <?php /* get the post ID into "postid" and later delete the post */ ?>
    <input type="submit"  value="Delete" />
</form>

一切都很好。现在是编辑公式。php是一个站点的页面模板，称为“Editiere Formular”。“editieren formular”是鼻涕虫。

<?php
/*
Template Name: Editieren Formular
*/

if( \'POST\' == $_SERVER[\'REQUEST_METHOD\'] && !empty( $_POST[\'action\'] ) &&  $_POST[\'action\'] == "edit_post" && isset($_POST[\'postid\'])) {
    $post_to_edit = array();
    $post_to_edit = get_post($_POST[\'postid\']);

    /* these are the fields that we are editing in the form below. */
    $title = $_POST[\'title\'];
    $description = $_POST[\'description\'];
    $vorname = $_POST[\'vorname\'];
    $name = $_POST[\'name\'];

    /* this code will save the title and description into the post_to_edit array */
    $post_to_edit->post_title = $title;
    $post_to_edit->post_content = $description;

    /* honestly i can\'t really remember why i added this code but it is a must */
    $pid = wp_update_post($post_to_edit);

    /* save taxonomies: post ID, form name, taxonomy name, if it appends(true) or rewrite(false) */
    wp_set_post_terms($pid, array($_POST[\'cat\']),\'firmen\',false);
    wp_set_post_terms($pid, array($_POST[\'post_tags\']),\'post_tag\',false);

    //UPDATE CUSTOM FIELDS WITH THE NEW INFO
    //CHANGE TO YOUR CUSTOM FIELDS AND ADD AS MANY AS YOU NEED

    update_post_meta($pid, \'vorname\', $vorname);
    update_post_meta($pid, \'name\', $name);

    //REDIRECT USER WHERE EVER YOU WANT AFTER DONE EDITING
    wp_redirect( \'http://crm-wordpress-theme.wellseo.de\' );

...

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