How to delete a column in DedeCMS?

DedeCMS is a commonly used content management system for building websites and managing content. In the process of using DedeCMS to build a website, we often need to manage columns, including deleting unnecessary columns. This article will introduce how to delete columns in DedeCMS and provide specific code examples for reference.

The steps to delete a column in DedeCMS are as follows:

1. Log in to the backend management system: First log in to the backend management system of DedeCMS and enter administrator rights. Only administrators with the right to delete columns Only then can the column be deleted.
2. Find the column you want to delete: In the background management system, find the column you want to delete. Columns are usually displayed in the tree structure of the column management page. Find the target column to be deleted according to your needs.
3. Delete a column: After finding the column you want to delete, select the "Delete" operation in the corresponding option. The system will prompt whether to confirm the deletion of the column. After confirmation, the column will be completely deleted.

In addition to deleting columns through the backend management system, we can also delete columns through code. The following is a sample code for deleting the specified column in the DedeCMS template file:

<?php
require(dirname(__FILE__).'/include/common.inc.php');

$arcID = isset($arcID) ? intval($arcID) : 0;

if($arcID){
    require(DEDEINC."/arc.partview.class.php");
    $pv = new PartView();
    if($arcID=='top'){
        $pv->SetTemplet(DEDETEMPLATE."/module/newspart.htm");
        GetTopAndEnd();
    }elseif($arcID=='end'){
        GetTopAndEnd("end");
    }elseif($arcID=="jspart"){
        require(DEDEINC.'/arc.sglistview.class.php');
        $sg = new SgListView();
        $sg->SetTemplet(DEDETEMPLATE."/module/jspart.htm");
        $sg->Display();
    // 其他栏目删除的逻辑代码
    }
}
?>

This code demonstrates how to delete the content under the specified column and re-render the page. Based on actual needs, more complex column deletion logic can be written on this basis. Of course, when using code to delete columns, you must be careful to ensure that other important content is not deleted by mistake.

In general, there are two main ways to delete columns in DedeCMS: operating through the background management system, or deleting columns through code. Choose the method that suits you according to the actual situation, and handle deletion operations carefully to avoid unnecessary losses to the website. I hope the above introduction can help users who use DedeCMS.
