How discuz implements automatic registration and login

Functions implemented in this article:

1. Enter the forum from the original system to automatically log in and register

2. Implement pop-up boxes on this page without jumping

3.js directly initiates a registration request when the page is loaded

This function was previously handled by the uc_user_register function, but today it will be used when developing user space problem appear.

Project requirements

Add a forum to our original system, but user information needs to be shared.

Implementation method: Bring the user information of the original system when entering the forum, and then get the information from the forum and register directly.

Enter the forum from the original system to automatically register and log in

then we need to put the original registration code into upload/template/default /touch/member/register.htm

The reason for putting this code is thatdsicuzThere will be many parameter restrictions when submitting the form, we can just keep it as it is.

<form method="post" autocomplete="off" name="register" id="registerform" action="member.php?mod={$_G[setting][regname]}&mobile=2">
   <input type="hidden" name="regsubmit" value="yes" />
   <input type="hidden" id="hash" name="formhash" value="{FORMHASH}" />
   <!--{eval $dreferer = str_replace(&#39;&&#39;, &#39;&&#39;, dreferer());}-->
   <input type="hidden" id="referer" name="referer" value="$dreferer" />
   <input type="hidden" name="activationauth" value="{if $_GET[action] == &#39;activation&#39;}$activationauth{/if}" />
   <input type="hidden" name="agreebbrule" value="$bbrulehash" id="agreebbrule" checked="checked" />
   <!--{if $_G[&#39;setting&#39;][&#39;sendregisterurl&#39;]}-->
   <input type="hidden" name="hash" value="$_GET[hash]" />
   <!--{/if}-->
   <!--{if $secqaacheck || $seccodecheck}-->
   <!--{subtemplate common/seccheck}-->
   <!--{/if}-->
   </div>
</form>

Then we need to directly send a request when the page is loaded, just add the following code.

Implement the pop-up box on this page, without jumping, and directly initiate a registration request when loading

The function implemented by this js code: directly initiate a registration request when the page is loaded, and then return the information , displayed directly on this page instead of jumping to another page

<script>
    var hash = $(&#39;#hash&#39;).val();
    var referer = $(&#39;#referer&#39;).val();
    $.ajax({
        type:&#39;POST&#39;,
        url:"member.php?mod={$_G[setting][regname]}&mobile=2" +&#39;&inajax=1&#39;,
        data:{
            "handlekey":"registerform",
            "inajax" : 1,
            "regsubmit" :"yes",
            "formhash":hash,
            "referer" :referer
        },
        dataType:&#39;xml&#39;
    })
        .success(function(s) {
            popup.open(s.lastChild.firstChild.nodeValue);
            evalscript(s.lastChild.firstChild.nodeValue);
        })
        .error(function() {
            window.location.href = obj.attr(&#39;href&#39;);
            popup.close();
        });
</script>

The last step required at this time is what form to use to transmit it from the original system. This method is not provided here. I will make a simulated data.

Add your own code according to the comments in the upload/source/module/member/member_register.php method on_register

Test the effect

We register a ceshi123 account
