问题描述
||
我想为每个评论添加ID，以便在任何成员对评论进行评论的情况下，INSERT和SELECT都知道在哪里显示评论，谁在评论中以及在什么评论中评论。这就像为每个注释创建一个ID，以便SELECT在其位置显示每个消息。但是我不知道这是要处理的html，PHP还是javascript问题。 jsfiddle在这里。
的PHP
我确实在网址字符串中选择了ID
$id = $_GET[\'id\']; // this id of the user being commented in the user table I guess I will need that id to identify which user is being commented \"profile\" that\'s the id of his profile
if (isset($_SESSION[\'id\'])) {
$userid = $_SESSION[\'id\'];
$username = $_SESSION[\'name\']; }
else {
// do this
}
// the userid contains the id and name of the user commenting \"the user logged in\".
if ($_POST[\'comment_field_1\'] != \"\"){
$comment_field_1 = $_POST[\'comment_field_1\'];
$comment_field_1 = stripslashes($comment_field_1);
$comment_field_1 = strip_tags($comment_field_1);
$comment_field_1 = MysqL_real_escape_string($comment_field_1);
$comment_field_1 = eregi_replace(\"\'\",\"'\",$comment_field_1);
$sql = MysqL_query(\"INSERT INTO comments (mem_id,commented_men_id,the_message,parent_id,message_date)
VALUES(\'$userid\',\'$idc\',\'$comment_field_1\',$parent_id Now())\")
or die (MysqL_error());
// i guess the $parent_id should be initialize somewhere in the top with a value of 0 or 1 depending weather it is a response or a comment.
}
// men_id is the field of the $userid,commented_men_id is the field for the commented on,$idc variable etc...
if ($_POST[\'comment_field_2\'] != \"\"){ // responses form field
$comment_field_2 = $_POST[\'comment_field_2\'];
$comment_field_2 = stripslashes($comment_field_2);
$comment_field_2 = strip_tags($comment_field_2);
$comment_field_2 = MysqL_real_escape_string($comment_field_2);
$comment_field_2 = eregi_replace(\"\'\",$comment_field_2);
$sql = MysqL_query(\"INSERT INTO comments (mem_id,sub_commented_id,$sub_commented_id Now())\")
or die (MysqL_error());
// here instead of $parent_id I use field created for responses to tag a comment as a response should be initialize somewhere in the top with a value of 0 or 1 depending weather it is a response or a comment. I am not sure weather I should leave the parent_id variable or come with this new field $sub_commented_id. What do you think?

解决方法
您将需要修改保存您的注释的数据库表，以添加\“ parent \”列。顶级注释的父ID为0，这意味着它不是对任何其他注释的响应。
响应将在其父列中具有顶级注释的ID。
修改表格后，您将需要修改PHP代码以识别对顶级注释的响应，并修改HTML以正确显示它们。
