评论未显示php

Question

我有一个将数据发送到我的数据库的表单，并且使用此表单我可以在我的帖子下面发表评论，但问题是：当我去一个帖子评论它时，我（先）插入一个评论和插入评论后，我可以看到其他评论，我不知道问题出在哪里

表单php

<system.webServer>
    <rewrite>
        <rules>
            <rule name="Redirect to https" stopProcessing="true">
                <match url=".*" />
                <conditions>
                    <add input="{HTTPS}" pattern="off" ignoreCase="true" />
                    <!-- avoid redirection for the following paths -->
                    <add input="{PATH_INFO}" pattern="^/service1/" ignoreCase="true" negate="true" />
                    <add input="{PATH_INFO}" pattern="^/service2/" ignoreCase="true" negate="true" />
                </conditions>
                <action type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" redirectType="Permanent" appendQueryString="false" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>
