HTTP: POST request receives a 302, should the redirect-request be a GET?

天涯浪子 提交于 2019-11-28 08:22:24
I was reading this but I didn't really got from there what request-type the redirect-request should have in what case, i.e. the function (initial request-type, response-type) -> redirect-request-type. In my particular case, I had: initial request-type: POST response-type: 302 Google Chrome used a GET for the redirected request. In the Python library requests , there is the following code ( here ): # http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3.4 if r.status_code is codes.see_other: method = 'GET' else: method = self.method I.e., the redirect-request-type is GET in case of 303

How to get the value of autoincrement of last row at the insert

时间秒杀一切 提交于 2019-11-28 08:16:32
I have googled this problem one week and no thing useful I think am not using the correct word I am using SQL Server 2008 with t-sql and my need is to optimise my function when I insert a new row. I have a table with first column is the key of integer autoincrement type and other columns are just for information When we do an insert, SQL Server increments the key automatically and I have to do a select max to get the value, so is there a way like a global variable like @@IDENTITY or a function to avoid the begin end transaction and select max Use SCOPE_IDENTITY : -- do insert SELECT SCOPE

jQuery $.get or $.post to catch page load error (eg. 404)

自闭症网瘾萝莉.ら 提交于 2019-11-28 07:35:25
How do you catch Server Error or 404 page not found, when you use $.get or $.post ? For example: $.post("/myhandler", { value: 1 }, function(data) { alert(data); }); That will do absolutely nothing if there is a Server Error loading "/myhandler", or if it is not found. How do you make it notify you if there is an error? Reigel use error handler on $.ajax() $.ajax({ url: "/myhandler", data: {value: 1}, type: 'post', error: function(XMLHttpRequest, textStatus, errorThrown){ alert('status:' + XMLHttpRequest.status + ', status text: ' + XMLHttpRequest.statusText); }, success: function(data){} });

How do I validate a form field in Codeigniter when using Get parameters?

坚强是说给别人听的谎言 提交于 2019-11-28 07:28:46
问题 I have a form that worked perfectly until I switched the form to method="get" . Now I can't get form_validation->run() to evaluate to TRUE. This is how I open the form: echo form_open( '', array( 'method' => 'get' ) ); This is the only piece that needs to validate: $this->form_validation->set_rules( 'states', 'states', 'required' ); This is how I check to see if the form is validated: if( $this->form_validation->run() == FALSE ) Is there something else I need to do to use Get parameters? I

PHP include() with GET attributes (include file.php?q=1)

蓝咒 提交于 2019-11-28 07:27:00
I want to include() a php file located on my server, with additional GET attributes. But it won't work: include('search.php?q=1'); The error it gives: PHP Warning: include(): Failed opening './search.php?q=1' for inclusion Seems like it tries to open a file literally named 'search.php?q=1' instead of opening the 'search.php' file and sending it the GET attributes. *Note that it does work if I don't put any GET attributes: include('search.php'); You don't want to do this: You'd have to do a http request to be able to pass GET parameters. A PHP script you call in this way will run in a separate
