[PHP] $_GET String Edit
Hey - this one should be simple. I am parsing some data and have $_GET variables in the URL stipulating on which record to start and how many records to display (these then get basses to the limit command in my database query). So here is the catch. I am trying to make a page navigation menu (we have all seen them, Page: 1 2 3...), and I would like to continue doing this via the URL variables. Right now, each of the page numbers is a hyper link is set like this: page.php?.$_SERVER[QUERY_STRING].more variables here. The problem, however, is that those variables are a string. If the variables that the menu defines are already in the string, it doesn't update them, it just adds more definitions to the URL. How have you people dealt with this? I am sure that there is some elegant solution and I would love to know what it is.

I had a hard time interpreting your question, but I think you're saying that you are generating URLs like this: /page.php?foo1=bar1foo2=bar2foo1=bar3foo2=bar4 And, you're wanting to not duplicate variables in your URL, correct? You could always keep your query string in an array or something. This would allow you to update values in the array prior to the end of your script. You can start this array using $_GET: $query = $_GET; Of course, you might want to rather filter this data on each page, so that you don't spread tainted data more than necessary. Regardless, this will allow you to update values in your query string. If you want to update foo1, you don't have to care whether it's already set: $query['foo1'] = 'newvalue'; Hope that helps.

Re: [PHP] $_GET String Edit
Sorry for the confusing initial request. You were correct in assuming that I am generating URLs like: page.php?foo1=bar1foo2=bar2foo1=bar3foo2=bar4 So I suppose the consise follow-up question is how can I get a hyperlink to change one of those varibles in the string. In the past I have just tacked a varible on to the end of the string, but I don't want to be redundant. Thanks again.

In the past I have just tacked a varible on to the end of the string, but I don't want to be redundant. To make this easy, I really think you need to not use a string like you keep suggesting and use some other data structure. I mentioned an array, simply because I think one of PHP's strengths is its rich collection of array functions. You can build your query string as the very last step, prior to using it in a link. While you are constructing it, I think you will find using a string to be about the most cumbersome approach possible. Hope that helps.
