Unable to pass value to another page.

Client Joined: Oct 07, 2003 Posts: 735 Location: Ohio

I have a couple pages I am working with.

One page named CombatAssets passes team_id to the page Movement.

But Movement does not pass the value onto the next page named Move.

CombatAssets does this.

Code:

<a href=\"modules.php?name=Campaign&amp;file=Movement&amp;team_id=$team_id\">" . _CLICK . "</a>

...with this at the bottom of the page.

Code:

. "<input type=\"hidden\" name=\"team_id\" value=\"$team_id\">"

The Movement page gets the value and I can display infomation based on the team_id which is what I want.

Code:

$id = intval($_GET['team_id']);


$sql = "SELECT * FROM " . $prefix . "_tc_ladderteams tclt WHERE team_id ='$id'";

I then have a dropdown onchange to pass the value onto the next couple of pages, and this is where I can't get the value passed correctly.

Code:

<select name="move" onchange="if(this.options[this.selectedIndex].value != 0){ document.location=this.options[this.selectedIndex].value; }">


<option value="0">--Choose option--</option>


<option value="modules.php?name=Campaign&amp;file=Move&amp;team_id=$id">Move</option>


<option value="modules.php?name=Campaign&amp;file=Attack&amp;team_id=$id">Attack</option>


<option value="modules.php?name=Campaign&amp;file=MoveAttack&amp;team_id=$id">Move and Attack</option>


</select>

At the bottom of Movement.php I have

Code:

echo"<input type=\"hidden\" name=\"id\" value=\"$id\">";

Then finally on my Move.php page I can't get the value and then display the unitname of the id I am trying to pass.

Code:

$id = intval($_GET['id']);


$sql = "SELECT * FROM " . $prefix . "_tc_ladderteams tclt WHERE team_id ='$id'";


$result = $db->sql_query($sql);


$info = $db->sql_fetchrow($result);


   if (!$result) {


      echo("<p>Error performing query: " . mysql_error() . "</p>");


      exit();


   } else {


      $unitname = $info['name'];


   }

Any help is appreciated.

Does the team_id pass in the browsers url? I mean does it have something in it?

With a link like http://yoursite.com/script.php?name=blah&var=blah2, There should be no reason to pass . "<input type=\"hidden\" name=\"blah2\" value=\"$blah2\">"

Basically the url contains the variables you want, but its upto you if youd like to POST it or GET it.

with the input, You could post it but then thered be no reason to put it in the url.

Finally is team_id populating in the url or not?

ohh yeah something else I just noticed:

$sql = "SELECT * FROM " . $prefix . "_tc_ladderteams tclt WHERE team_id ='$id'";

wont work try:

$sql = "SELECT * FROM " . $prefix . "_tc_ladderteams tclt WHERE team_id =".$id."";

Yes it appears in the url of the browser. From my page CombatAssets

modules.php?name=Campaign&file=CombatAssets

I can go to any one of the links that will send me to the movement page for that team.

modules.php?name=Campaign&file=Movement&team_id=5

I then select which type of movement.

Code:

<form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="POST">


<center><b>Commanders Menu<br>


<select name="move" onchange="if(this.options[this.selectedIndex].value != 0){ document.location=this.options[this.selectedIndex].value; }">


<option value="0">--Choose option--</option>


<option value="modules.php?name=Campaign&amp;file=Move&amp;team_id=$id">Move</option>


<option value="modules.php?name=Campaign&amp;file=Attack&amp;team_id=$id">Attack</option>


<option value="modules.php?name=Campaign&amp;file=MoveAttack&amp;team_id=$id">Move and Attack</option>


</select>


</form>

But I cannot get the team_id passed to the pages Move, Attack, or Move Attack.

For the move page this shows up in the url.

Code:

/modules.php?name=Campaign&file=Move&team_id=$id

I have this in my Move.php page where I am trying to GET the value

Code:

$id = intval($_GET['id']);

ok your trying to grab id from the url, id is not in the url, team_id is.

Try $id=intval($_GET['team_id']

other then that, Id seriously need a look at the code, I am trying to map the script in my head but its quite difficult.

and if this is your url, to a T=/modules.php?name=Campaign&file=Move&team_id=$id Then that means that your script is taking $id literally.

If this is the code that makes you change pages then it should look like <option value="modules.php?name=Campaign&file=Move&team_id=".$id."">Move</option>

I hope this helps.

I then echo unitname out in my Move.php page and it is blank so that tells me that I am not passing the $id.

*EDIT*

At one time I had Movement.php doing all these things. Move, Attack and whatever. I could not get that working either.

OK. I decided to go back to my first design of this page, instead of breaking it up into three seperate pages. I can write to the database the values of ateam_id which is attacking team and the tid which is the territory id. I can also write the timestamp and action.

I cannot as yet write the dteam_id. It is left blank. I think it would be a good idea to also list the drop down box to select the current territory name that team is on. The selected value.

Here is what i have so far.

Well d***...Sentinal wont let me post that code either.... Mad

It doesn't like the words Enemy, Attack, and Combat.

LOLOL

I could always give you access to take a peak and lend your assistance. I'd love to get this working soon. People are waiting on me.

Posted: Tue Oct 03, 2006 9:02 pm

Please by all means, e-mail me the work you have now, Ill play with it, Im sure I can get it working, e-mail is darklord@darklords-lair.com

Ill make notes and let you know all the edits I make.

instead of echoing $unitname try to

print_r($info)

and see which part of the array is getting filled with your call, See if you want name, then you shouldnt call * but it should be name. else, call multiple calls.

Posted: Tue Oct 03, 2006 10:32 pm

I've never used print_r(anything) in my life. How do I use it?

registered · Posted: Wed Oct 04, 2006 1:01 pm

print_r() is a function used to print out an array. It functions almost the same as an echo

Posted: Wed Oct 04, 2006 3:50 pm

k....

That telle me what it does, but not how to use it.

Posted: Wed Oct 04, 2006 4:40 pm

the same line you used to echo $unitname, type print_r($info);

What it will output if it applies considering $info is an array, print_r should output the contents of the array, for example,

$sql="Select username From ".$prefix."_users WHERE uid='1'";//query
$result=$db->sql_query($sql);//Run the query
$info=$db->sql_fetchrow;//Grab the information from the query in an ARRAY!!!

Now in order to use the $info variable youll need to either $info['0'] or $info['username']. This you probably already new is an array.

Now instead of echoing $info['username or 0'] we can print_r($info); and it will output

Array ( [0] => Anonymous [username] => Anonymous )

So now we know for a FACT that the array is being populated but I honestly think its the sql statement that is NOT filling the array as you intended.

Ok. I clicked on my unit and this is what came out.

Quote:

Array ( [0] => 3rd Infantry Division [name] => 3rd Infantry Division [1] => 1 [team_id] => 1 )

So I am getting team_id and it is the correct one.

Did you get my email?

I think I already covered this and had it working in my original movemetn.php script.

Now I am trying toget the territory list box to list the selected (current value) of the team.

My code for the territory array is

Code:

$sql = "SELECT tid, t_name FROM " . $prefix . "_eto_territories";


$res = mysql_query($sql) or die(mysql_error());


while ($rec = mysql_fetch_assoc($res))


$territories[] = $rec;

My array for territory looks like

Code:

Array ( [0] => Array ( [tid] => 29 [t_name] => Cornwall ) [1] => Array ( [tid] => 30 [t_name] => Somerset ) [2] => Array ( [tid] => 31 [t_name] => Hampshire ) [3] => Array ( [tid] => 32 [t_name] => Cambridge ) [4] => Array ( [tid] => 33 [t_name] => Essex ) [5] => Array ( [tid] => 34 [t_name] => Aberdeen ) [6] => Array ( [tid] => 35 [t_name] => Sussex ) [7] => Array ( [tid] => 36 [t_name] => Kent ) [8] => Array ( [tid] => 37 [t_name] => Devon )

Now I am trying to find the current value.
