I have a query string in the URL:
?search=whatever
I need to append this to paginated links:
example.com/articles/p3/?search=whatever
I can get the value using:
$_GET['search'] //whatever
But what's the best way to build the string so I can append to my URL. Is there a proper way or would it just be a case of appending a string:
'?search='.$_GET['search']
For building url's you always should use propper urlBuilder.
For PHP you can use parse-url and http-build-query.
If it's only one variable you are going to use on that page it is ok to use
'?search='.$_GET['search']
But you should also make sure that you care for encoding that var with urlencode() somewhere in your code (where the var is initially set up).
If you want to build an URL with multiple args there is a nice little function called http_build_query() which can help you with that.
Yeah just do
$search = $_GET['search'];
$pagecount = 10; //Count of results from DB or similar pagination data. ie skip take etc..
for(i=0;i<$pagecount;i++){
echo "<a href='getmoreresults.php?search=".$search."&page=".$i."'>$i</a>";
}

Hoping this is a simple and easy question. I've seen multiple examples of, and know how to append variables to the URL (i.e. mydomain.com/index.php?id=1&stat=0), but my question is this:
If I have a page on my site that already has variables in the URL (i.e. mydomain.com/tickets.php?stat=Open), how can I append a page number to the end of that URL (i.e. mydomain.com/tickets.php?stat=Open&page=2). This is for pagination purposes of a table with values from my database, that includes a search and select function (select open, closed, or all tickets, and search for a specific ticket number).
I've done several searches with google, and came up dry, as most topics regarding this have you hardcode the url with variables from the get go, and not append them. I may just be using the wrong search parameters as well, and am not sure what to search for exactly.
Any help or insight on this would be greatly appreciated, thank you.
Please note I wish to do this solely in PHP, HTML, and MySQLi. I want to refrain from using javascript or ajax if possible for my clients that may have those features disabled on their browsers.
Using this way:--
<?php
$domain = "mydomain.com";
$page = "tickets.php?";
$full_page_url = $domain.'/'.$page;
$arr = array('stat' => 'Open', 'page' =>2);
$add= http_build_query($arr);
$correct_url = $full_page_url. $add;
echo $correct_url;
?>
output:--mydomain.com/tickets.php?stat=Open&page=2
I would do it like this:
$page = 2;
$url = 'mydomain.com/tickets.php?stat=Open';
if( false !== strpos($url, '?')){
//if url has a ? split it.
$arr_url = explode('?', $url);
//convert query string to array, $array=['stat'=>'Open']
parse_str($arr_url[1], $array);
//add or replace page by array key
$array['page'] = $page;
//convert it back to a query string.
$query = http_build_query($array);
print_r($query);
}
Outputs
stat=Open&page=2
It's a simple matter of putting $query back with $arr_url[0] I'll leave this up to you. But I will give you a hint $arr_url[0].'?'.$query
The advantage here is that you don't have to worry about getting into a situation where you are adding page after page after page after...
Like this:
mydomain.com/tickets.php?stat=Open&page=1&page=2&page=3
You can't simply concatenate it onto the end of the url, and it's probably just as hard to remove it as it is to parse the query string.
As a side note, you could just use $_GET but where is the fun in that, as $_GET is the query string already parsed as an array ( so you could skip parse_str). But it may not be on a request, such as if you were just building the link from a string.
So I thought I would show it with parse_str to cover the "harder" case.
One last thing if you are just building a bunch of urls all the same except the page part. The obvious answer is to setup a base url and then just loop out the numbers.
$url = 'mydomain.com/tickets.php?stat=Open';
$pagedUrls = [];
$numberPages = 10;
for($i=1; $i<=$nubmerPages; $i++){
$pagedUrls[] = $url.='&page='.$i;
}
Or what have you for the number of pages.
It's really not that clear in your question exactly what you are trying to do..
Hope that helps.
I need to pass a url using a GET address. To give an example which was I have tried:
http://www.example.com/area/#http://www.example.com/area2/
I've also tried replacing the forward slashes with other characters but that doesn't seem to work. How would you pass a url in a GET?
As I have understood, you should use url_encode() and url_decode().
The function url_encode() lets you create a string that can be used as a link.
You should use it this way:
$link = 'goto.php?link=' . url_encode($_POST['target_site']);
And when you were going to redirect to the user defined site (eg), you can decode the parameter given this way:
$decoded_link = url_decode($_GET['link']);
// Now it's safe to use the given URL (for example I can redirect to there)
header('location: ' . $decoded_link);
Hope it helps.
The # character links to an anchor on the page. The browser will automatically scroll to the element with the id after the point sign. So that's not what you're looking for.
To pass a GET parameter, the syntax would be like this:
http://example.com/area?http://example.com/area2
Then, if you var_dump($_GET), you'll see your URL. But, if you have other fields you also want to pass in your URL, you can use key=value pairs, like so:
http://example.com/area?url=http://example.com/area2¶m1=a¶m2=b
In this case, your URL will be available in $_GET['url'].
For example, if there is a url like www.website.com/hello/richard, would it be possible to echo hello and 100 separately onto my page.
eg:
hello how are you today richard
You can get the data from $_SERVER['REQUEST_URI'] and then do whatever you like with it.
Yes it would be. Try this:
$myURL = $_SERVER['REQUEST_URI'];
$myTokens = explode('/', $myURL);
echo $myTokens[1] . "blah" . $myTokens[2];
This code gets the current URL into the myURL variable, then it calls a function called explode which turns it into an array based on the position of the '\' character. Then it echos out certain elements of that array. If you play around with output using echo you will soon see for yourself what is going on.
Sure that's possible. You can get URL as a string using $_SERVER['request_uri]. Then you might want to use explode function to firm array of strings where delimiter is /. Then you may parse it. Or you can do this via .htaccess using rewrite rule
I have a URL like:
http://www.google.com/test.html?d=1232&u=32
and I want to add it as a part of a GET query string like:
http://www.mysite.com/index.html?a=123&d=http://www.google.com/test.html?d=1232&u=32
Note the double "d" used. I want the URL sent to be just a url and not be read for it's query string...
What is the best way to do this to avoid problems?
You can use the urlencode() function.
Example:
$url = 'http://www.mysite.com/index.html?a=123&d='
. urlencode('http://www.google.com/test.html?d=1232&u=32');
You can use urlencode() to put that in the URL without having it interfere with anything else you have in there.
URL-encode the second url:
http://mysite.com/index.html?a=123&d=<?php echo urlencode('http://google.com/etc..'); ?>
You can assign a url to a variable and have it be query-string safe by using urlencode() (http://us3.php.net/urlencode). So you could do:
$url = 'http://www.mysite.com/index.html?a=123&d=' . urlencode('http://www.google.com/test.html?d=1232&u=32');
In this example the query-string var 'd' now houses all the contents of the second url. You will have to urldecode() it on the receiving end in order to extrapolate the data.
I am hoping someone can help me, I have created url's like this
/this/is/a/test/index.asp
/this/is/a/test/index-1.asp
/this/is/a/test/index-2.asp
/this/is/a/test/index-3.asp
What is the easiest way to strip the number from the URL?
Instead of using variables like this:
/this/is/a/test/index.asp?no=1
/this/is/a/test/index.asp?no=2
/this/is/a/test/index.asp?no=3
to create variables I am using the number in the URL to dynamically call the content on the page.
If the url is: /this/is/a/test/index-3.asp it should use the 3 and match the content according to it, similar as if I were to call
?no=3
I am using PHP for this...
The url structure will always have the variable define as match the last '-' [the-number] '.asp'
Thanks

You could use mod_rewrite to map URL patterns to actual URLs. You could achieve what you want with something similar to the following:
RewriteRule ^index-([0-9]+).asp$ index.asp?no=$1
You should be able to match it out with:
if (preg_match('/\-(\d+)\.asp$/', $_SERVER['REQUEST_URI'], $a)) {
$pageNumber = $a[1];
} else {
// failed to match number from URL
}
