I wasn't sure how to word this but the easiest way to describe what I mean is just by giving an example.
Take this site -> http://lolprofile.net/summoner/lan/rimortix . When you search for a summoner the user in this case rimortix changes but the page renders the same just with a different users info. They don't use index.php?user=rimortix which would make sense to me on how it would work. How do they dynamically query for user info in this url layout?
The site I used was just an example but I have seen this same layout many times.
I came across this and it was exactly what I was going for.
Dynamic url in php without filename

I'm a Wordpress virgin, thrown into something I don't know much about, just trying to help. I do know a few things about php.
I would like to know if somehow in wordpress (not via an update vulnerable hack) it is possible to see and manipulate the full page content, before it is displayed ?
I would like to check a few things in the page meta-data tags, cross reference that with data in the body on various places, make a few changes here and there if needed and THEN hand it over to Wordpress again.
Some sort of callback, at the last moment, with the full page's content in a php variable.
Maybe this is simply not possible ?
Hope to learn something. Cheers.
Before making a CSS change that might possibly have unintended consequences, what's a good way to find where else on the whole site (not just this page) that id or class is used? (It doesn't have to be exhaustive, and semi-manual processes are ok, too.)
For a bit of context, it's a Joomla-based site with a lot of content, and I'm not yet familiar with most of it. The id in question has a two letter name, and I have no idea where else it might be used. I don't have direct access to the server for any grep-like approaches.
The only technique I can think of is using Stylish to make an obvious change to that one selector, and browsing the site for a bit to see where it pops up.
The easiest way would be a local grep, but since you don't have access to the server, try downloading it locally using wget:
wget -r -l --domains=http://yourdomain.com http://yourdomain.com
That'll recursively retrieve pages from your domain to an infinite depth, but only following links to pages within your domain.
Once it's on disk, do a local grep and you're golden.
I use unused-css.com for this sort of thing. You simply put in your webpage, and it will look through the whole site (incl. login) and give you the CSS that you actually are using.
I've found it to be 95% correct - but it only doesn't pick up on things like some CSS browser hacks and some errors (ie. the CSS only displays after an error), so it should work fine for this.
You could also check the original template (assuming the template is a commercial one) to see where the id perhaps should be (they usually lay everything out in their demo template), but unused-css won't tell you exactly where it is used, only if it is or not. For that, I'd start with a view-source -> find on the major pages, and then try other mentioned solutions.
Get the whole site's source tree into an IDE like NetBeans or Eclipse and then do a recursive search for id="theid" on the root folder.
If this is not possible, how are you updating the CSS?
Assuming you don't want to do the grep approach:
Is the ID in question appearing in the actual content area of the page, or in the 'surrounding' areas? If it seems like it's not part of the content, but rather appears in a template, you could search the template files for it. As you're updating the CSS, I'm going to assume you can at least get a hold of the template files. Many text editors/IDE's will let you do a 'global search'. I'd load the template files in TextMate (my texteditor of choice) and do a "search in project" for the particular ID.
That will at least give you a semblance of an idea of where in the site that ID shows up. No, it won't be every 'page', but you'll know what kind of page it appears on (which, with a CMS, is really what you're after).
If the ID in question appears in the content, that is, it was hand-entered by content creators, you'll have to go another route. Do you have access to the database? If you can get a dump of the database (I think Joomla! is MySQL based), you can open the sql in something like Sequel Pro and do a search in the content records for that ID.
This is not actually as hard as it sounds. First place to look the index.php file for the template. This file should be pretty small without a ton of code unless the template is from a developer that uses a template framework. If the ID is in there, then it will show up on every page in the website since this is the foundation that every page is built on.
If you don't find it in there, then you need to determine whether it is displaying in a module position or in the component area. You should be able to tell the difference by looking at the index.php file from the template.
If it's in a module position, then the ID should only show up in instances of that particular module.
If it's in the component area, then it should only display in any pages being created by the component. That does leave the possibility of it affecting many elements you don't want changed. But there is a solution for that. you can use the page class suffix in a menu item to add a unique id/class to the page you want to change (depends on your template). With that unique suffix you can create a specific selector that will only affect the pages you want to change.
There are a number of different websites that let you monitor specifi web pages for any changes, such as watchthatpage.com or page2rss.com
I'm interested in the way how those sites are working, meaning how do they determine whether some web page is updated. Do they just copy all the text from the page, store it in memory and compare it later to the content of a site's page?
Or maybe they look for some specific html elements and compare theirs values?
Please help me to find the answer.
How it works: http://www.watchthatpage.com/information.jsp
I suspect that they store the entire contents, and every time they check, they compare. If different, send alert, otherwise don't.
There's two ways this can be done just off the top of my head.
The first is to pull the HTML and do a simple string.compare.
The second way, would be to do a HEAD request See, section 9.4 here
I need a little help understanding how HTML forms work. It is my understanding that forms that use GET as their method submit name/value pairs for all fields within the form tags of said submission. However, if you take a look at the follow example from Google (and I've seen this in many other places too) and only use one of the fields on the form:
http://books.google.co.uk/advanced_book_search
Rather than being sent to a page with a name/value pair for each field of the advanced search page you are taken to a much cleaner looking URL:
http://www.google.co.uk/search?tbo=p&tbm=bks&q=hitchiker&num=10
Despite all of the input fields on the advanced search page.
Onto my problem... My own advanced search page is quite large and at the moment is being POSTed to my search results page which is taking in the values and searching accordingly, no problems! However, I want my users to be able to bookmark/share their searches and in order to do this I need to have items being passed into the querystring but I don't want massive querystrings if I don't need them. If my user has only searched by a color for example then I want the URL to be something like search.aspx?color=red; If they're searching by color and size then search.aspx?color=red&size=large and so on. Is this possible?
To complicate things even further I'm using ASP.NET so it's not the easiest of things to create a form that uses GET though I do believe I have already found away around this.
If you can give any advice or a nudge in the right direction, then thank-you! :)
What you're suggesting should be easily possible if you conditionally check the querystring on the results page to ensure the key/value is there.
if(Request.QueryString["color"] != "")
{
// Add color to the seach parameters
}
To create the GET request I would think you would need to POST back to your search form and redirect to the results form from there, dynamically adding key/values to the querystring as and when they are required. This Post/Redirect/Get design pattern is typically used with web forms to help with book marking.
If you want to share bookmarked searches between users, then you'll have to share the name/value querystring options in the posted URL. It sounds like you don't want to include the pair if one wasn't specified. That's easy, just dynamically build a querystring for pairs that the user HAS provided input for. So, when processing, loop through all input controls, and if a value was provided, append it to the querystring, or not.
Right now, when I create a media item, I can view it as admin by going through the Media then clicking on view, eventually I end up at [mysite]/blog/?attachment_id=31 which is a nice reduced version of the image (which can be clicked to appear large), and which has the nice feature that there is a place to leave comments at the bottom.
This is great for administrators. But I want anonymous users to be able to look at 5 different, fairly similar images, and make comments on the pages separately. So I'd like for the anonymous users who navigate to [mysite]/blog/?attachment_id=31 to find the same page the way it looks to admins.
But when going to that URL as an anonymous user instead of the image with comment form I get:
Sorry, no posts matched your criteria
So, how can I enable this permission for anonymous users?
If this is not possible, please rephrase the question as, "What is the best way to use Wordpress to get a bunch of anonymous people to vote on 5 different layouts and also to be able to comment on each of them separately, as I am trying to do at http://christian-filipina.com/blog/ ? (None of these are public URLs, please don't link to them.)
Do I need to create a page for each of those separate layouts and then use HTML to link to the variously-sized versions of the images?
When adding an image to the post make sure that "attachment page" is checked instead of "image file" This should fix your problem. See: http://codex.wordpress.org/Using_Image_and_File_Attachments
