PHP - Url Query String Tracking.

Hi there,
im trying to have a form show up when user clicks "add joke". I need the variable to be retrieved from the url query string. I cant get the form to show up.  I think its either an issue with the GET function at the top or the link down at the bottom. Please help!


<?php
  // If the user wants to add a joke
  
    $_GET['addjoke'] = $addjoke;

  if (isset($addjoke)):
?>

<FORM ACTION="<?php echo($PHP_SELF); ?>" METHOD=POST>
<P>Type your joke he <BR>
<TEXTAREA NAME="joketext" ROWS=10 COLS=40 WRAP>
</TEXTAREA><BR>
<INPUT TYPE=SUBMIT NAME="submitjoke" VALUE="SUBMIT">
</FORM>

<?php
  else:

    // Connect to the database server
    $dbcnx = @mysql_connect("servername", "username", "password");
    if (!$dbcnx) {
      echo( "<P>Unable to connect to the " .
            "database server at this time.</P>" );
      exit();
    }

    // Select the jokes database
    if (! @mysql_select_db("jhodara2") ) {
      echo( "<P>Unable to locate the joke " .
            "database at this time.</P>" );
      exit();
    }

    // If a joke has been submitted,
    // add it to the database.

$joketext = $_POST['joketext']; 
$submitjoke = $_POST['submitjoke']; 

    if ("SUBMIT" == $submitjoke) {
      $sql = "INSERT INTO jokes SET " .
             "JokeText='$joketext', " .
             "JokeDate=CURDATE()";
      if (mysql_query($sql)) {
        echo("<P>Your joke has been added.</P>");
      } else {
        echo("<P>Error adding submitted joke: " .
             mysql_error() . "</P>");
      }
    }
  
    echo("<P> Here are all the jokes " .
         "in our database: </P>");
  
    // Request the text of all the jokes
    $result = mysql_query(
              "SELECT JokeText FROM jokes");

    }
  
    // When clicked, this link will load this page
    // with the joke submission form displayed.
    echo("<P><A HREF='$PHP_SELF?addjoke=1'>Add a Joke!</A></P>");

Greetings,

I'm looking for a way to pass a query string (from page1) as part of a query string (to page2) as a single key=>value pair. The idea is the use the query string to return the user to the previous page after the action has been completed.

query results[page1]->view record/action selection[page2]->back to results[page1]

I'm sure someone has been down this path before. P.S. the script is all contained within one file, thus the filename.ext is already known.

Thanks

Thanks in advance for help.
I have a PHP script that has a function called traverseXMLNodes and it passes an xml string. I want anyone with a username and password to be able to call this function from his website or application or programming. In short i want my site to act as an API(Application Programming Interface).

 I am really stuck as to how to go about this. There are other functions i would like to call as well so traverseXMLNodes  is not the only function i want to my "API" users to access.

Below is the code I am using. the filename for my php i called remote.php. I am using the following query string to test and no results are returned.
http://localhost/testfolder/remote.php?xmlstring=20


Code: [Select]
<?php
$allowedfuncs = array('xmlstring','remotefunction2');
 
if(in_array($_get['xmlstring'], $allowedfuncs))
{
    $func = $_get['xmlstring'];
    $output = traverseXMLNodes($func);        // This calls $_get['funccall']()
    echo $output;
}
else
{
    exit();
}
 
 function traverseXMLNodes ($func) {
 
 echo "The XML string is";
 echo "<br/>";
 echo $func;
 echo "<br/>";
 }
/*
More functions go here
*/
?>

hey @requinix, I know you and I have talked about this before but I just want to clarify this issue.  Sadly, I have produced very few websites that have made use of dynamics in the form of database querying.  But, the next project that I'm looking at will require it.  The last thing I did with a query string involved the recording of downloads of file on a website.  and on the page, I had this code:

The archive is located he    <a href="dl.php?f=archive.zip">archive.zip</a>

and the ''dl'' page had this code:

if(!$_GET['f']) error('Missing parameter!');

        $stmt = $conn->prepare("INSERT INTO tblDownloads (ip, file, date, time) 
        VALUES (?, ?, ?, ?)");
        $stmt->bind_param("ssss", $ip, $file, $date, $time);
        $stmt->execute();
        $stmt->close();
        $conn->close();
	
	    header("Location: archive.zip");
	    exit;

and all the variables in the above ''dl'' page are declared in a file that is required by it, called ""conn.php"".

My question for anyone here is:

I am going to be producing a website similar to the testing site called ""jsFiddle"":  https://jsfiddle.net/ .  And it is slated to have a huge amount of content on it.  for example, a main page might have 100 links on it whereby, if a user clicks on any of them, it should take them to another page (or load async content) that illustrates and example of any given issue being asked about.  So, I know we've talked about $_GET before Requinix, and how most websites use it to produce dynamic content.  And we've also talked about the concept of markdown.  But once again, can someone here remind me....what's the best way to go about doing this?  Storing the actual ""answer to the issue"" content in a backend database and pulling/displaying it appropriately, kind of like what I am showing I did with the file in the above code?  thanks.

Stumped on this. I copied the syntax of this from another site I'd done (where it works) Then I changed the query, of course.
But I'm getting an error, that I'm not sure I understand:
The page prints: 451made it to here
Warning: mysql_query() expects parameter 1 to be string, resource given in /home/workshop/public_html/register5b.php on line 20

Hi,
My issue here is that I cant get my query string variables to ONLY feed into if/else statement  on my secondary page. I include my secondary page (fine.php) from my index page. My query string variables keep being fed back into my original if/ese statement on index.php.

here is the if/else on index.php (these links work fine):

<?php
if($_SERVER['QUERY_STRING']=='/index.php' || $_SERVER['QUERY_STRING']=='')
{
include 'port.php';
}

elseif (isset($_GET['pos'])){
include 'pos.php';
}

elseif (isset($_GET['web'])){
include 'web.php';
}

elseif (isset($_GET['fine'])){
include 'fine.php';
}

        else {include '404.php';}






here is the if/else on my secondary page (fine.php). These links are supposed to alert the if/else in the next table cell. However, they instead alert the if/else in index.php.


<td><br/>
<a href="?backset"><img src="fine/thumbs/x-backset.jpg" border="0"></a><br/><br/> 
<a href="?backside"><img src="fine/thumbs/x-backside.jpg" border="0"></a><br/><br/> 
<a href="?bannerprint"><img src="fine/thumbs/x-bannerprint.jpg" border="0"></a><br/><br/> 
<a href="?chopu"><img src="fine/thumbs/x-chopu.jpg" border="0"></a><br/><br/> 
</td>
<td><br/>
<div id="DivPiece" align="left">
<?PHP 

if (isset($_GET['backset'])){
       include 'fine/backset.php';
}

elseif (isset($_GET['backside'])){
     include 'fine/backside.php';
}

elseif (isset($_GET['bannerprint'])){
     include 'fine/bannerprint.php';
}

elseif (isset($_GET['chopu'])){
include 'fine/chopu.php';
}

?>
</div>
</td>



How can I get the links on the secondary page to only alert the if/else statement on that page, and BLOCK the if/else statement on index.php from seeing them? I still want to use the query string though.

Thanks!

I have this form

<form action="" method="get" name="size"> Størrelse <hr><label><input type="radio" value="9" name="size" onchange="this.form.submit()">92 (2år)</label>


<label><input type="checkbox" value="147" name="size" onchange="this.form.submit()">68 (6-9 mdr.)
</label><label><input type="checkbox" value="150" name="size" onchange="this.form.submit()">86 (18-24 mdr.)</label>
<input type="checkbox" value="149" name="size" onchange="this.form.submit()">80 (12-18 mdr.)</label>
<label><input type="checkbox" value="148" name="size" onchange="this.form.submit()">74 (9-12 mdr.)</label>


</form>

I want to make it so that when the user clicks one checkbox for example size 68 and then checks size 80 I want both sizes to be in the URL query string. But every time the user clicks a new checkbox, the query string changes accordingly. Maybe with a separator like ?size=4:23 and then I will handle it with the DB stuff.   Please tell me how to add multiple elements in the query string with this form, thank you!

appreciate any help

I want the page to refresh on with the query string, but this isn't working for me...

Code: [Select]
header("Location: " . $_SERVER['php_self'] . "?" . $_SERVER['query_string'] );

Okay so i have a URL like this..

https://www.mysite.com/board/profile.php?user=1

I want the URL to be like this..

https://www.mysite.com/user/1

.htaccess rewrites have always confused me.

Hello!   I'm hoping this makes sense. Basically I have this code:   What it does 1) Looks at the XML 2) Looks for the PIN number in the URL, then finds it in the XML 3) Returns values for the PIN number (which is a profile) allowing me to do echo statements like name, tools, description, etc.

<?php
if (!empty($_GET['pin']))
{
$feedURL = 'http://www.inveroak.co.uk/readerimages/livepanel/91255.xml';
$showOpsWithNoPics = false;

try

$xml = simplexml_load_file($feedURL . '?' . time());

    }
    else

    if ($picture != '')

What I am want to achieve 1) Looks at the XML 2) Looks for a set PIN number in the CODE, then finds it in the XML 3) Returns values for the PIN number (which is a profile).  

Hi, how do I store as a string (in a variable) a mysql query b/c what I'm doing below outputs Resource id in client browser:

Code: [Select]
<?php
//database connection set up etc
$show=mysql_query("SELECT file_Name FROM xdocument WHERE doc_id=95");
print $show;
?>

Any help much appreciated, thanks.

Hi, i have a query string id=5&start=0 that i want to remove from the url and return the url without it. I am searching a cleaner way for doing it. Here is an example :

Before : http://www.example.com/?a=3&id=5&start=0
After : http://www.example.com/?a=3

Before : http://www.example.com/?id=5&start=0
After : http://www.example.com/

Before : http://www.example.com/?alpha=1&id=5&start=0&beta=2
After : http://www.example.com/?alpha=1&beta=2

Thank you

Hey all,

When someone clicks a link, link looks like this:

http://site/homes/edit/1?image=true

Now on the same page, I have another link, which posts to the edit method as well, but no query string passed:

http://site/homes/edit/1

I want to check if image key is set to true and basd on that, determine which view to render for the user, that is, whether to display the edit form to edit post or the image form to edit image. But by using the get array to try to grab query string:

Code: [Select]
if($_GET["image"]=="true"){


I get the following error:

Message: Undefined index: image

It appears that $_GET is not successfully grabbing the parameter.
