Set more variables to URL

Hello,
I'm currently editing a php script. The current URL is /file.php?id=2. I got an form which sets limit_rows so after refresh the url should look like /file.php?id=2&limit_rows=500
May its cause I'm too tired but what i get out of this is /?&limit_rows=500.

May you find whats wrong or what i forgot to add.

Code:

---

?>
        <center>
        <h5>Enter number of lines you want to see.</h5>
        <table>
                <form action="&" method="get">
                        <input type="text" name="limit_rows" />
                                <br/>
                        <input type="submit" value="Refresh" />
                </form>
        </table>
        </center>
        <br>
<?php
        echo isset($_GET['limit_rows']) ? htmlspecialchars($_GET['limit_rows']) : '';

---

And no, the ?> isnt wrong, i just don't wanna copy&paste a 2k line script ^^.

Thanks for help.

Code:

---

        <form action="<?=$_SERVER["REQUEST_URI"]?>" method="get">

That should already do the trick (because its writing the old GET-parameters into the form-address).

Doesnt works, it redirects me to a different page (may cause some includings).

Can you look in the source-code and write here what PHP added to the formular? It shouldn't be possible that it directs you to another page (maybe Echelon is doing it on missing parameters).

Code:

---

                <form action="/echelon/clientdetails.php?id=2" method="get">
                        <input type="text" name="limit_rows" />
                                <br/>
                        <input type="submit" value="Refresh" />
                </form>

---

But i get redirected to clients.php

Does it also redirects you to clients.php if you type the url (/echelon/clientdetails.php?id=2) directly into the browser? :confused:

If i type in /clientdetails?id=2&limit_rows=500 it shows 500 rows and also show up the standart value in the text box (500). So the limit_rows define when i type in by myself.

Well okay, i made some changes and the problem is may the overgiving of the URL.
Yes, i messed the code a littlebit up but i get my outputs that tells me that everything should be allright.

Code:

---

        $newURL = $_SERVER["REQUEST_URI"];
        echo $newURL;
       
        $_GET['limit_rows'] = 500;

---

Sets the actualy URL and output it, also sets the limit rows to 500 (to test)
Output:

Code:

---

/echelon/clientdetails.php?id=2

---

next parts:

Code:

---

        $newURL .= "&limit_rows=".$_GET['limit_rows'];
       
        echo $newURL;
        echo "<br>";
       
        if(isset($_GET['limit_rows']))
        {
                $newURL .= "&limit_rows=".$_GET['limit_rows'];

                echo isset($newURL) ? htmlspecialchars($newURL) : '';
        }

---

Outputs:

Code:

---

/echelon/clientdetails.php?id=2&limit_rows=500
/echelon/clientdetails.php?id=2&limit_rows=500&limit_rows=500

---

Even the second line works fine if i set it manually to the url.

Actually Form:

Code:

---

        <center>
                <h5>Enter number of lines you want to see.</h5>
                <!--<form action="<?//=$_SERVER["REQUEST_URI"]?>" method="get">-->
                <form action="<?php $newURL ?>" method="get">
                        <input type="text" name="limit_rows" value="<?php echo $limit_rows?>" onblur="if(this.value == ''){ this.value = '<?php echo $limit_rows?>'; }" onfocus="if(this.value == '<?php echo $limit_rows?>'){ this.value = '';}" />
                                <br/>
                        <input type="submit" value="Refresh" />
                </form>
        </center>
        <br>

---

So the URL is fine, the overgive of the URL should be fine, the old one should output the same. Idk whats wrong at here, i still get redirected to clients.php if i click on the refresh button.

Any ideas?

And btw, I'm working now 3 hours on this error ^^
