问题 I have a program. It accepts an input of a alphanumeric string (which I already do checks for). So a valid input would be www.example.com/myfile.php?input=John1 However, if someone were to type in www.example.com/myfile.php?input[] then it breaks my entire program's logic breaks because I don't accept input as an array. How can I unsure the thing a user enters is just a string. Not an array, or any other data types/structures? 回答1: There is the slow and tedious way of solving this problem,

问题 Using VS2010 VB.NET, I have a datagridview (dgv) where I set the background color of cells according to a certain value. This particular cell does not store any information and therefore I can not use the data in that cell to determine the background color. My current attempts are a complete failure and MSDN is only particular to "setting" and not "getting" the background color of a cell. Code I've tried" if dgvNotes.Rows(clickedCell.RowIndex).Cells(1).Style.BackColor.ToString = "Red" then if

问题 I want to encode a specific search field before submitting as a $_GET request. What I am doing is to apply encodeURIComponent() function over that field before the form is submitted $('#frmMainSearch').submit(function() { var field = $(this).find('#searchinput'); field.val(encodeURIComponent(field.val())); }); the issue is that as soon as the text is encoded, the field displays the encoded text which looks a bit weird. Is there anything I can do to avoid it? Example: I type Hello & Hello .

问题 I have a number of PHP pages with query strings in the URLs on my site. I'm trying to change the URLs for SEO, to do this I'm using an .htaccess file.

问题 Assuming I am not running server side scripting of any kind, how can I set and get a cookie from within VBA code? 回答1: I saw a posting about this that might help for setting the cookie: link text Here is his code snippet: Sub test() Dim w As New WinHttp.WinHttpRequest Dim t As String, qs As String qs = "this=that&more=less" w.Open "POST", "http://www.comparity.net/perl/form.pl?a=b", False w.setRequestHeader "Cookie", "one=foo" w.setRequestHeader "Cookie", "two=bar" w.send qs t = w

问题 Today I run into some oddity with PHP, which I fail find a proper explanation for in the documentation. Consider the following code: <?php echo $_GET['t']. PHP_EOL; ?> The code is simple - it takes a single t parameter on the url and outputs it back. So if you call it with test.php?t=%5Ca (%5c is a '\'), I expected to see: \a However, this is what I got: $ curl http://localhost/~boaz/test.php?t=%5Ca \\a Notice the double slash. Can anyone explains what's going on and give recipe for

问题 I inherited an XP machine with xitami/pro server running on it and installed PHP 5.2.17 because I thought I might need the VC6 version. PHP works and the phpinfo shows as it should. When I do www.domain.com/test.php?x=y&z=test the $_GET is not being populated. The $_REQUEST variable is not being populated either. If I post it in a form and post it, the $_POST is empty as is the $_REQUEST . If I loop through the $_SERVER variables and display them on a get, the QUERY_STRING is populated with
