POST Data to php file on xammpp server

2022-05-19T02:56:48+08:00

I am trying to POST data from a PicMicro 18F47K40 which is controlling a
Solar Tracker using a ESP8266.
I have updated the ESP8266:-
AT version:1.7.5.0(Oct 9 2021 09:26:04)
SDK version:3.0.5(b29dcd3)
compile time:Oct 15 2021 18:05:30

The problem is I cannot get it to post the data, all other commands work OK
I was trying originally with 8 variables but have now just setup a 2 field
Database to test it. Sending a POST from a browser using the same PHP files
it works OK. But when sent from ESP8266 it comes up with "Undfined Array Key"
which is because the server is not reciveing the POST variable information.
This is the Commads sent:-

Code:

AT+CIPSTART=0,"TCP","192.168.1.103",80\r\n
AT+CIPSEND=0,132\r\n
POST /insert.php, HTTP/1.1\r\n  
Host: 192.168.1.103\r\n         
User-Agent: Mozilla\r\n    
Content-Type: application/x-www-form-urlencoded\r\n\r\n"]   
\r\n\r\n
Content-Length: 20\r\n     
\r\n\r\n                      
Col_1=,Dec Value1,&Col_2=,Dec Value2,\r\n\r\n    
\r\n\r\n

The response from ESP8266:-

AT+CIPSTART=0,"TCP","192.168.1.103",80
0,CONNECT

OK
AT+CIPSEND=0,132

OK

 record created successfully
0,CLOSED

It does access the PHP file and adds a record to the Database but
the field values are empty.

Obviously the command sequence is not correct or I have somthing wrong
any help or suggestions would be good, thank you.
