Discussion
Reference:
What are you talking about?
If there are three pages a, B, and c, $ _ GET ['rkno'] and $ _ GET ['type'] are uploaded from page a to page B through get, then, post a $ _ POST ['kw _ info'] from page B and connect it to the previous $ _ GET ['rkno']. the value of $ _ GET ['type'] is uploaded to the c page. In this case, values of $ _ GET and $ _ POST can be obtained. I want to add the three values to a form on the c page ......
------ Solution --------------------
Does the $ kw_info obtained on page c have no value? Output:
Echo $ kw_info = $ _ POST ['kw _ info'];
------ Solution --------------------
He should input a value on page a and submit it to page B, while Page B's If no value is selected, go to the c page and use post to retrieve the value. on page B, we recommend that you get $ kw_info to the url, change $ kw_info = $ _ POST ['kw _ info']; to $ kw_info = $ _ REQUEST ['kw _ info'];
