PHP - $_get And Url Parameters
I got two links with a parameter with a value. When I click either link it will send me to the same challenge.php page, I'm wanting to find the value of the parameter and display the page according to what value the parameter has in the url.
This script doesn't seem to be working. Code: [Select] <a href="http://www.site.com/challenge.php?id=1">Complete Challenge 1</a> <a href="http://www.site.com/challenge.php?id=2">Complete Challenge 2</a> Code: [Select] $id = $_GET['id']; if ($id=1) { echo "This is challenge 1 completed"; } elseif ($id=2) { echo "This is challenge 2 completed"; else { echo "The URL parameters didn't work"; } Any help would be appreciated thanks. Similar TutorialsI am calling CURL and trying to do a POST request with parameters: Code: [Select] $curl = curl_init(); curl_setopt($curl, CURLOPT_HTTPHEADER, Array("Accept: application/json", "Content-Type: application/json")); curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 15); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true); curl_setopt($curl, CURLOPT_USERAGENT, "curl 7.23.1 (x86_64-unknown-linux-gnu)"); curl_setopt($curl, CURLOPT_USERPWD, "username:password"); curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC); curl_setopt($curl, CURLOPT_URL, "https://www.mydomain.com/route"); curl_setopt($curl, CURLOPT_POST, true); curl_setopt($curl, CURLOPT_POSTFIELDS, "key1=blah1&key2=blah2"); return curl_exec(curl); The problem, inside the request at http://www.mydomain.com/route I am not seeing any POST parameters passed. I.E. Code: [Select] print_r($_POST); Code: [Select] Array ( ) Should have key1=blah1 and key2=blah2. Any ideas? A few months ago, and a good amount of time before that, I had people telling me to use isset() instead of performing to see if the variable is empty, such as: !$_GET[''] I know the differences in the function and what they do, but when could isset() be used in a situation where it's better/more efficient then: !$_GET[''] I do use isset(), though. I have some function or method. Is there a better design patter to implement this?
function myFunction($a=null,$b=null,$c=null,$d=null,$e=null,$f=null,$g=null,$h=null)
{
//Do a bunch of stuff
}
Maybe the second function?
function myNewFunction($data=array())
{
$data=array_merge(array('a'=>null,'b'=>null,'c'=>null,'d'=>null,'e'=>null,'f'=>null,'g'=>null,'h'=>null),$array);
//Do a bunch of stuff
}
Please provide decision making factors why you would use one approach over the other.
Hi, I develop some functions in PL/SQL and PL/PgSQL. In these languages are IN and OUT parameters in Functions and Store Procedures. There is IN and OUT parameters in PHP Functions? Sorry my bad english. Best Regards, Hi hello, Right now I have this generated URL: mywebsite.com/thisismypage?compare0=50&compare1=112&compare2=512 Is there anyway to "extract" the 50, 112, and 512 dynamically? Those numbers are the Item ID's, I need them for further operations. So is there a way to extract the IDs, maybe into an array? The ID's are dynamically rendered, as well as the "compare#". Not sure if I am being clear... hopefully this makes sense. All help is appreciated. Thank you. I am making a function it returns one thing, but I would the like to put something into a variable to use outside the function. for example, the third parameter in preg_match() sets a variable that you can then use later in your code, how can I create a parameter like that?
Not experienced coding PHP and need help doing something which is probably very easy but looks like Mt Everest to me. FOO = 123456 BAR = abc Then, write URLs with those variables and have them work the same in a browser:
http://webpage1.com/?var1=FOO&var2=BAR
http://webpage2.com/?var1=FOO&var2=BAR
http://webpage3.com/?var1=FOO&var2=BAR If I update the fields in my local webpage and refresh browser, would like the new value(s) to be used instead. Any help with this greatly appreciated. If someone will put a file together think that I can edit and modify from there for my specific application. Thank you. Edited December 1, 2020 by XcloneHi all, I need to get a parameter from an url, but the GET variables are passed through urldecode(). Some of my variables may have characters such as "+", ":", spaces, etc. When I use GET, all "+" are converted to spaces. I can use urlencode to get the "+" back, but also everything that was previously a space also turns into "+". Example: variable = abc+ c+:d Then I can get either: abc c :d or abc++c+:d but I want to get abc+ c+:d Would anybody know how to help me? Thanks! Is there an alternative way to encode url params besides: base64_encode() examples would be great. Hello all, I'm kind of a noob to PHP, and as such have been teaching myself the language. I'm attempting to insert tag attributes in divs, based on whether the site is viewed in IE or Firefox, to account for subtle differences in appearance. The problem, however, is that the variable $boxorlink apparently has the value "box" the second time I call the method, even though I explicitly state "other" as the parameter; the else clause is never reached. If anybody could tell me why this is happening, please let me know.

However, after reading some more about PHP, I noticed that I need to include the function mysql_real_escape_string before doing this line: @mysql_query( $aStatement); So, how can I read that $aStatement and then call the mysql_real_escape_string function for each needed parameter? Thanks. This thread is about what you can and cannot call Variables and Parameters in a Function... I have this query which returns 1 or 2 for $gender... Code: [Select] // Check # of Records Returned. if (mysqli_stmt_num_rows($stmt1)==1){ // Member was Found. // Bind result-set to variables. mysqli_stmt_bind_result($stmt1, $firstName, $username, $photoName, $photoLabel, $gender, $birthYear, $location, $occupation, $interests, $aboutMe); And here is my Function... Code: [Select] function displayGender($gender){ if ($gender == 1){ $gender = 'Male'; }elseif ($gender == 2){ $gender = 'Female'; }else{ $gender = ''; } return $gender; }//End of displayGender Questions: 1.) Is it a problem having $gender as both my Parameter and Argument? 2.) Is it a problem renaming $gender inside the Function like I do? 3.) Is it a problem returning $gender like I do? Thanks, Debbie So I'm creating a website for bar deals... I've tried for hours trying to get the url to take in more than one parameter with no luck, I don't know if my database isn't setup correctly or something but the url would look like this http://www.site.com/?id=1&day=Monday and when those parameters are passed the deals for that id and day are then posted in the content area I'm pretty much stumped. I feel like it's much easier than I am making it. My database looks like: ID Name Monday Tuesday Wednesday -> and so on 1 Bar1 MondayDeal TuesdayDeal WednesdayDeal 2 Bar2 MondayDeal -> and so on I'm making a game in php and I'm wanting users to scan a QR code to get a URL, which takes them to a page on my website. I need the URL to have a parameter to identify the QR code and then be able to give the user a reward according to what QR code took them to the website. Anybody have any idea how I would go about this? Thanks. Hello All, I have created a web application. Unfortunately at development time I forgot to encrypt my query parameter. So generally my apply URL shown like : http://mysite.com/myprofile.php?userId=2 So here any user can guess some other Ids because User Ids are not encrypted in URL. Is there any simple way to do it. I have more than 100 php pages and implementing ecry/decry logic on each page is time consuming So is there any way around? Regards, Prateek Hi everybody, I wrote a web service and I need to pass parameters through url in order to make a record in a mysql db. The problem is that when I insert greek characters in url it translates it to something like this http://xxxxxx.xx/test3.php?name=%CD%E9%EA%EF%F2&pass=234 and I got an error. Does anybody have a suggestion? Please help because I search for this many hours and still nothing. Thanks for your time Hi all I need to combine URL parameters using the following forms: <form id="type_filter" name="type_filter" method="get" action=""> <label for="type_filter"></label> <select name="type" id="type_filter" style="width: 160px" onchange="this.form.submit();" > <option value="" selected class="meter-calc-text">Product Type</option> <?php $fetchtypes=mysql_query("SELECT * FROM `product_types` ORDER BY id ASC"); while($returnedtypes=mysql_fetch_array($fetchtypes)) { echo "<option value=\"".$returnedtypes['id']."\"".(($returnedtypes['id']==$_GET['type']) ?

' selected="selected"':'')." >".$returnedcolours['name']."</option>"; } ?> </select> </form> At the moment they only send one parameter each. How do I drop down on one and add it to the parameter already on there to give this URL: ../stone.php?type=1&colour=1 Many thanks Pete echo "bitches" . "<br />"; class classname { function _contruct($param) { echo "Contructor called with parameter ".$param; } } $a = new classname("First"); $b = new classname("Second"); I'm trying to run this code but it's not giving me any output. Output should be very simple, e.g, Constructor called with parameter First. Please help. Hi, I am somewhat new to PHP but I have a little experience. I am having trouble coding this script to set variables with extra quotations and replacing some exploded strings. Here is the script. Code: [Select] <?php $ToCutDown = "[{"parentMessageId":-1,"message":"%3Ca%20href%3D%27%23%27%20class%3D%27standardLink%27%20onclick%3D%27showMobStats%28674542538%29%3B%27%3Eaka%20Bubbles%3C%2Fa%3E%20broadcast%20a%20message%3A%20%3Cfont%20color%3D%27red%27%3E%22Place%20Bounty%20on%20%26quot%3Baka%20Bubbles%26quot%3B%20%28Minimum%20of%20%2418%2C107%2C899%2C000%29%22%3C%2Ffont%3E%2E","id":28152301,""; $Exploded = explode("[{"parentMessageId":-1,"message":"", $ToCutDown); $Exploded = explode(","id":28152301,"", $Exploded[0]); $Exploded = urldecode($Exploded[1]); $StringReplace = str_replace("<a href='#' class='standardLink' onclick='showMobStats(674542538);'>", "", $Exploded); ?> So I'm trying to work with specific strings that have quotation marks in them (Which cannot be removed) & I'm having a hard time using them in variables and in any function that requires you to choose parameters with either ' ' or " ". Any suggestions would be appreciated thanks MOD EDIT: [code] . . . [/code] tags added. Hi guys, I have coded this, however I have received an error msg, can someone advice me in this?
