There are two approaches:

<ol>
<li>You can do it using the JavaScript's <code>localstorage</code></li>
<li>You can do it using PHP's <code>$_SESSION[' ']</code></li>
</ol>

Both will follow the same mechanism, when user loads the webpage for the first time, set a variable as <code>true</code>. Now for the next visits check this variable, if it is set to true, don't load the first page and redirect it to your classical page.

blocks|key|1269908|text|从drupal文档中：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1269909|https://api.drupal.org/api/drupal/modules!user!user.module/function/user_cookie_save/7.x|offset|length|1269910|您可以做的是:首先检查是否设置了cookie。如果不是，则设置它。下一次用户访问你的站点时，他/她会有一个cookie，这样逻辑门就会通过。|1269911|下面是一个示例，您可以在drupal的头文件中使用它：|1269912|if+(!isset($_COOKIE['some_descriptive_cookie_name']))+{

From the drupal docs:

<a href="https://api.drupal.org/api/drupal/modules!user!user.module/function/user_cookie_save/7.x" rel="nofollow noreferrer">https://api.drupal.org/api/drupal/modules!user!user.module/function/user_cookie_save/7.x</a>

What you can do is: You first check if a cookie has been set. If not, then you set it. The next time the user visits your site, he/she will have a cookie so the logic gate will be passed.

Here's an example that you can use in your header file in drupal:

<pre><code>if (!isset($_COOKIE['some_descriptive_cookie_name'])) {
 user_cookie_save('some_descriptive_cookie_name');
 drupal_goto('temp/page/here', [], 307);
}
</code></pre>

<code>drupal_goto</code> is documented here: <a href="https://api.drupal.org/api/drupal/includes%21common.inc/function/drupal_goto/7.x" rel="nofollow noreferrer">https://api.drupal.org/api/drupal/includes%21common.inc/function/drupal_goto/7.x</a>

Good luck.

blocks|key|3586108|text|Drupal几乎可以处理所有事情。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3586109|我要做的是在用户配置文件中创建一个布尔私有字段，用于存储用户是否已经看到该特定页面。|3586110|按照这种方法，您还可以生成关于有多少用户查看了该页面的报告，或者知道某个特定用户是否查看了该页面。在Drupal中，使用字段可以为您提供强大的功能。|3586111|当用户看到页面时，如何存储此值？检查规则模块，不要忘记激活规则UI，这样您就可以配置由上述条件触发的操作。|3586112|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|L|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|M|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

Drupal can handle almost everything.

What I would do is to create a boolean private field in the users profile to store if the user already saw that particular page. 

Following this approach you can also make reports about how many users have seen that page, or know if a particular user saw that page. Using fields gives you a lot of power in Drupal.

How can you store this value when the user sees the page? Check the rules module and don't forget to active the rules UI so you can configure this action triggered by the mentioned condition.

blocks|key|5054400|text|您可以使用hook_user_login。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|5054401|function+MODULE_user_login(&$edit,+$account)+{
++//+The+user+has+never+logged+in+before.

You can use <code>hook_user_login</code>.

<pre><code>function MODULE_user_login(&amp;$edit, $account) {
 // The user has never logged in before.
 if ($account-&gt;access == 0) {
 // Redirect user when first login.
 $_GET['destination'] = 'redirect_url';
 }
}
</code></pre>

I am working on darskite project in case of crisis. For this project we want to prepare a specific case.

We need to inform the user visiting our website of the crisis (eg : our factory has an electrical failure). We want to show him this specific page of information only during the first time he comes in our website. For the next visits, he must visit our classical homepage.

How can we target and identify a user to redirect him only once to the alert message (when he first logs in)? Are there any solutions like those for retargeting Google or Facebook via cookies? If Yes, what kind of cookie ?

Our website is powered by Drupal 7. Can Drupal handle this case?

Thank you for your ideas.

display a specific page only the 1st time user visite our site
