In the previous sections, We have mainly published the summary and demo examples in the previous 10 sections.

If you are interested, you may wish to study it, I believe we can still find some different ideas.

This section will continue to lead the way to unveil the Post Submission mechanism of QBlog in the autumn garden.

 

Start:

The Post Submission mechanism of QBlog in the autumn garden is actually very simple: 1: place a hidden domain in the Form in html. 2: When the Form is submitted to the background, the Post event is distinguished and triggered by hiding the agreed name and value of the domain. 3: In a custom life flow, the process is simple and relevant.

 

I. Post Processing Mechanism in a custom Process

 

First, a picture that has been used several times:

 

Note:

This is the second life cycle in the Custom life process of QBlog in the autumn Garden. The Post trigger mechanism is here.

OnPost: protected virtual void OnPost () {}. This is a virtual function that will be overwritten and processed by various pages.

Before calling this function, there are several minor judgments and a special PostBufferOK function.

PostBufferOK: This is a buffer mechanism. In addition to secondary submission prevention, it also provides a certain range of second-kill code submission functions.

PS: In the past, it was often found that foreigners often sent comments with links to the QBlog in the autumn garden, which showed that foreigners also had this hobby.

 

2. hidden fields corresponding to the interface

 

Basic html:

<Form method = "post" enctype = "multipart/form-data">
<Input type = "hidden" name = "myAct" value = "Setting"/>

... Then there are some submitted text boxes and a submit button. The description with enctype includes the upload function.

</Form>

Note:

The name convention of the hidden domain is "myAct", which corresponds to the background, while "value" is left to the handler as the corresponding branch. After you click a submit button to submit, in the above custom lifecycle process, and then to the specific page below for processing.

 

Iii. ASHX processing program

Note:

Based on the value of the hidden field, use switch to differentiate event processing. How can I obtain the submitted value? Answer: Request [Control name]
