You'd have to use javascript but you can use PHP to check the value of said variable and then echo out the relevant javascript.

i,e:
Expand|Select|Wrap|Line Numbers
  1. [php]
  2. $variable = 0; 
  3. if($variable == 0){
  4.     echo "<script type=\"text/javascript\">";
  5.     echo "alert(\"The variable is 0\")";
  6.     echo "</script>";
  7. }
  8. [/php]

I am trying to make a prompt that will ask the user for some input... If I just use var input = prompt("dafa") everything works fine but the box is put in the top left corner of the window. I need it to be centered so... I was doing some research on the net (never really used much JavaScript before) and was reading the only way to do this is by making your own custom prompt. In my attempts of doing so I came up with this code below. The...

In my ASP.NET application, I wish to have a page for administrators to edit items in a list. Preferably, I would like to use the javascript prompt for the 'rename' function, and a javascript alert box for the 'delete' function. When the user clicks 'rename', the javascript prompt asks for the new name. When the user clicks 'delete', a javascript alert asks the user if he really wants to delete that item. Here is an example of what my...

Hello all, I didn't use to have this problem in Access 97, but in 2007 (and maybe other versions of access after 97), if you have a form that has a subform, and you click the close button, you always get the following dialog: "Save changes to the following objects?" I tried putting a saverecord command prior to the close, but that had no affect. I have found a work around, but maybe I am making this too

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
