How discuz controls the display of bullet boxes independently

In a previous article Wrote, discuz implements automatic registration and login. But we don't want that prompt message to come out.

After a brief search on the Internet, some said that the background can be set, but when I took a look at the back, I found that the setting was only for certain fixed scenes.

Then we can write a display method suitable for our project

Analysis of pop-up box implementation

Anyone who has used it for a while discuz knows that the front desk The pop-up box is actually determined by the background showmessage method.

We used code to trace that this method is in the upload/source/function/function_core.php file, about line 1424

Then we are tracking dshowmessageThis method

The final file of this method is upload/source/function/function_message.php here

Then we pull the code to the end, and we can see a variable of show_messge and a template address loaded

At this time we Find the location of this template: upload/template/default/touch/common/showmessage.htm

In this template we can see a variable show_message .

In order to confirm that the show_message in the template and the show_message in the PHP file are consistent, let’s do a test

Modification: upload /source/function/function_message.php Line 238

Then test the results on the page and there is no problem. The two variables are consistent

Implement your own display method

After the above test, we learned that the upload/source/function/function_message.php file The show_message on line 238 is consistent with the show_message of the template upload/template/default/touch/common/showmessage.htm.

Then we can declare a variable. If you want to display your own style, declare a variable and then control it in the template.

The following is a KaKa case: as long as you have this requirement KaKa Ka’s solution can 100% solve your problem

This code is to determine whether the user is registered, and if so, log in directly. (No need to worry here, Kaka’s case came from the original system.)

You can see that I added a new variable in showmessage called is_login, and the value is 1

Since we need to use this value in the template, let’s follow suit and declare is_login as a global variable in the upload/source/function/function_message.php file

Then with this value you can use it in the upload/template/default/touch/common/showmessage.htm template

Add yourself to this If is enough

There is also a particularly simple way to control entry in line 239 of upload/source/function/function_message.php Template

#So what needs to be done at this time! Just build this template

Copy the showmassge file in the upload/template/default/touch/common directory

Then modify this file, let Just jump directly after entering.

Achieve the effect

showmessage('login_succeed', 'forum.php',['username'=>$username,'is_login'=>1],array('showdialog' => 1));
