The key point is the reading of php and the php call of value in html.

Modify program article.modify.handle.php

392a60549ca019ed1bbf57562f31d8e5alert('Article modified successfully');window.location.href=' article.manage.php';2cacc6d41bbb37262a98f745aa00fbf0";
}else{
echo "3f1c4e4b6b16bbbd69b2ee476dc4f83aalert('Failed to modify article');window.location.href='article.manage.php ';2cacc6d41bbb37262a98f745aa00fbf0";
}
?>

5.5 Article Deletion

First do a demand analysis: It is slightly different from the above. Deleting an article does not require an interface, just a delete button to delete it . So there is only one file. The key sql statement is only one sentence

$delsql="delete from article where id=$id";

aritcle.del.handle.php

require_once('../connect.php');

//Read the id number. Unlike others that pass values ​​
$id = $_GET['id'];
$deletesql = "delete from article where id=$id";
if(mysql_query($deletesql) ){
echo "3f1c4e4b6b16bbbd69b2ee476dc4f83aalert('Article deleted successfully');window.location.href='article.manage.php';2cacc6d41bbb37262a98f745aa00fbf0";
}else{
echo "3f1c4e4b6b16bbbd69b2ee476dc4f83aalert('Failed to delete article');window.location.href='article.manage.php';2cacc6d41bbb37262a98f745aa00fbf0";
}
?>

5.6 Article Management List

Requirements analysis: A list displays all articles, followed by two buttons, Delete (link to the deleted module in the previous section) and Modify (link to the previous module)

So, you only need one file, just display the module

article.manage.php
