PHP misses url parameters

Hello Everybody,

I have a problem getting parameters from url in php. I am using this code:

if(isset($_GET["Letter"]))
{
    $Letter = $_GET["Letter"];
}
else
{
    $Letter = "";
}
if(isset($_GET["Industry"]))
{
    $IndustryID = $_GET["Industry"];
}
else
{
    $IndustryID = "0";
}

The code would get the parameter first time I run the page but if I want to reload the page with different parameters it would not get them and would use the parameters from the previous load instead.

I run this code on a joomla web-site through the Sourcerer plugin. However when I try running the same code on my local machine everything works just fine.

Does anybody know what’s causing this problem? Would it be a joomla issue? Any help would be appreciated. Thanks in advance!

so long as the page you are on has a query string like:
http://yoursite.com/yourpage.php?Letter=abc&Industry=efg

Your code should work fine.

Note, you can shorten your code to:

if($_GET['Letter'])
{
      $Letter = $_GET['Letter'];
}
else
{
      $Letter = "";
}
if($_GET['Industry'])
{
      $IndustryID = $_GET['Industry'];
}
else
{
      $IndustryID = "0";
}

else

    $IndustryID = "0";
}

This could also be written like this:

$Letter = isset($_GET["Letter"]) ? $_GET["Letter"] : "" ;
$IndustryID = isset($_GET["Industry"]) ? $_GET["Industry"] : "0" ;

I like saving space with my code.

My failometer has shot off the end of the scale!

I seem to have misplaced my ban button.. no wait... found it!

Thanks for help guys, but I still couldn't figure out what is causing the problem. The url does look like mysite.com/search?Industry=19&Letter=A but the parameters are still not taken into the code. Any ideas?

I actually found a solution. When a joomla web page opens for the first time it is cached on the server. When it is requested later the cached copy is opened instead of new one. That is why it uses the parameters submitted when the page was loaded first. I just had to turn the caching off to make the site working as needed.

pls i want to write a code for a each state in a map to link each other

Marc Firth1-Jun-09 5:14

so you want to know what exactly? You need to be a bit more specific. Post code you've written so far etc. What exactly do you mean "link to each other"?

Do you mean you have a map (i.e: of the US) and you want users to be able to click on different areas of it? If so, then you will probably want to use the <map> and <area> tags.

e.g:

<pre>

<img src="yourImage.jpg" width="480" height="467" border="0" usemap="#Map" alt="buttons" />
      <map name="Map" id="Map">
         <area shape="rect" coords="6,27,282,136" href="state1.php" alt="State1" />
         <area shape="rect" coords="6,170,282,278" href="state2.php" alt="State2" />
      </map>

</pre>

Neonlight,

i have the map already save on jpg but inside the map contain each states of different map. i want a code that will click on each states inside the map and it will take me to their states website. Thanks for the reply Neonlight your code is perfect, but i still need more clarification.

Marc Firth3-Jun-09 21:49

3-Jun-09 21:49

Well, I'm not going to write it all for you. Do some research on the map and area tags (Google them). If my code is perfect you should have everything you need in my last post.

yah, have trace the map using dreamweaver map cutting, pls teach me the functionality.
neolight pls give your light to it. Smile | :)

For each sate trace its outline:
<area shape="poly" coords="288,94,353,129,366,100" href="#">

This is in the format:
<area shape="poly" coords="x,y,x,y,x,y" href="#">
Where each "x,y" is a point of your polygon hotspot.

If you are using dreamweaver, click the image and look for the "polygon hotspot tool" (bottom left).

You can make the hotpsot using that - then just change the hyperlinks

That's your lot. Google the rest. If you don't try and figure it out for yourself you won't remember it. But, if you still need help learning html I suggest visiting <a href="http://www.w3schools.com">http://www.w3schools.com</a>

My apologies if this has been mentioned before, but I searched, and could not find the reference i need. On the device in question there is a legacy NTFS partition, that i have my old VM stored on. The partition is mounted in fstab, but not unlocked. This is a slight annoyance once VMware Server 2.0 services start. The DataStore never scans the legacy partition properly, and the inventoried VM is inaccessible, making me remove and add the VM every time. Also crippling any possibility of me making the VM start on boot.

After stating the background, i was wondering if there is any way possible to create a script, which will run before the VMware services start, and will unlock the volume. I only recently started using any Linux OS's, and this is the first linux install i have used on an actual machine (all others were observed in VMware). An unlock command, and the proper method for implementing it at boot would be appreciated.

My apologies is this question is seen as irrelevant, or outside the boundaries of this forum. I simply couldn't think of anywhere better to seek assistance.

(OS:Ubuntu ... please don't poke fun... i really enjoy using Mint, but this seemed more suited to the device)

Have you tried using ntfs-3g ?

darkdragn1-Jun-09 7:10

Thank you for the reply, but ntfs-3g is the driver type associated with it by default. The search for a resolution continues.

Moreno Airoldi1-Jun-09 7:20

My pleasure, too bad it wasn't the solution you need.

Btw can you explain what is it you exactly mean with "locked" ? I guessed you mean "read only", but I might be wrong. Smile | :)

Yes, my apologies for not clarifying earlier. The volume is successfully mounted, and visible from Nautilus, however basic system processes do not read it properly until i browse it. In Nautilus it appears as a media device, and after browsing to it once it gains an eject symbol.

An example of processes not being able to read it properly would be the VMWare services. When i launch the VMware management utility (Web based since I am using VMWare Server 2.0, however in all seriousness on windows machines i preferred 1.0.9, I simply figured a change of OS might also insinuate a change in pace to a more progressive outlook.) and it scans the Datastore pointing to the legacy partition it returns the values and properties of the filesystem partition. That is until I have browsed it, and it appears unlocked. I tell the utility to rescan the Datastore, and it will finally return the proper information. Either way, though, the VM in the inventory reads null, after this process, and it requires me to remove it from the inventory and re-add it before it can be utilized.

For some reason i get the feeling that I'm possibly missing something simple... or blatantly obvious to the experienced Linux user. Again thank you for taking the time to analyze this issue.

Ok now I think (hope) I get it. Poke tongue | ;-P

Your problem is your NTFS partition was "registered" in the system by Gnome's automatic mounting system. You can see it on your desktop, but it is NOT mounted! It gets automatically mounted when you first open it manually. This is achieved, for example, with the noauto option in fstab.

What you need is that your partition is automatically mounted at boot time. Edit your fstab and create or modify the line to do that. For example:

/dev/mypartition  /my/mount/point  ntfs-3g  defaults  0  0

You might need to change the defaults option to suit your specific needs.

Post your fstab if you need more help with it. Smile | :)

I am trying to make a PHP admin control panel, and have it set up, but I have 2 problems.
The first one is the control panel is not working. This is the code I am using:

The error I get is this:
Error: Duplicate entry '0' for key 1

How should I fix this? I have the entry form in the right way, so it's not that, and I know I have the login details right.

My second problem is that I can't select the user that I would like to edit. How could I fix that? The table with the usernames and passwords is called users, and I have the login script setup so you don't need to worry about that. Thanks! Wink | ;)

EDIT!:

This script actually creates users, not edits them. How would I fix that?

I think the problem is you are trying to create the same row in the table twice.

Create an "id" field set to auto_increment as your primary key. Then you can pass it a NULL value.

Also, I'm not sure about your post code in the SQL. Try:

$password = $_POST['password'];
$userlevel = $_POST['userlevel'];

$sql="INSERT INTO users (id, password, userlevel)
VALUES
(NULL, '$password','$userlevel')";
