表单发布操作：未在$ _POST中查看查询参数

I have a small PHP application (MVC) with a form. The action looks something like this:

<form action="<?php sprintf("/v/.../update?job=%s", $job->id);?>" method="post">

Here $job is a PHP object I pass the view from the controller. I hold onto the id field (an integer) so that I can update the row in the database corresponding to the object.

I'm not seeing this value in $_POST (it is in $GET, though) when I step into my update function for a post request. How should I retrieve this value? Is this expected?

Try to get by $_GET['job'] or remove 'job' from action url and send in hidden text field to get as $_POST['job'].

Also I think your action url is not creating. use echo

<form action="<?php echo sprintf("/v/.../update?job=%s", $job->id);?>" method="post">

you pass your job param as url string, and in this case it can be seen in $_GET or $_REQUEST arraies not $_POST whatever your form action get or post, because this param isn't form input.
