What should I do if php cannot get the post?

Solution to the problem that PHP cannot obtain post data: 1. Open the [php.ini] configuration file; 2. Check the [enable_post_data_reading] option and make sure it is open; 3. Make sure the browser uses the local Apache server .

Solution to not getting post data when php form submission:

Beginner to php, use echo $_POST Neither ["variable"] nor var_dump($_POST) can obtain post data.

The solution is as follows:

1. Find the php.ini configuration file, look for the enable_post_data_reading variable, and make sure it is open:

2 Observe the address of your browser running php, you will find that the service port number used to open the browser in PhpStorm is 63342 (URL is in the form of localhost:63342/)

So the cause of the problem is: PhpStorm By default, the built-in internal server is used, but the apache server in xampp is not used. The built-in server phpStorm uses port 63342, and there is a problem within the server, causing the POST method to be abnormal;

If you put the project in the working directory of the Apache server, enter localhost in the address bar, Apache is used at this time Server, the default port number is 80, and the Apache server can run the program normally.

Since there is a problem with PhpStorm’s internal server, the solution is to find a way not to use the internal server. There are two methods:

1. Create the project in the working directory of the Apache server, and directly enter the localhost address in the browser address bar each time it runs.

2. If you still want to use the Open the browser debugger in PhpStorm, which can be achieved by changing the configuration:

(1) First map the apache server directory to the local directory

The method is as follows:

1. Find /xampp/apache/conf/httpd.conf file

2. Find the code block

3. Add the following code to the child level:

# /phpworkspace/ : 其它磁盘上目录的别名, 就是你想映射过来的目录的别名 
# "E/phpworkspace/" : 这个是目录的绝对路径 
Alias /phpworkspace/ "E/phpworkspace/" 
# 现在就可以通过 //localhost/phpworkspace/ 访问到 E盘下phpworkspace文件夹里的项目了

4. Add a piece of code at the same level, as follows:

    AllowOverride All 
    Options Indexes FollowSymLinks Includes ExecCGI 
    Require all granted

Completed. Now restart Apache and visit: http://localhost/phpworkspace/ That’s it

(2) Then in PhpStorm , find File->Settings->Build, Execution, Deployment->Deployment in order. It is initially empty. Click the green plus sign to add a local server. Just name it localhost. Select In place for Type:

After the creation is completed, the default settings under the Connection tab on the right have configured the server as the Apache server under port 80, that is, http://localhost

Change it Set the Local path under the Mappings tag to the working directory of your local project:

At this time, click the browser from PhpStorm. The accessed URL no longer has the field 63342 port. Instead, the local Apache server is used, and the corresponding form data can also be received normally.
