Nothing shows up!![not resolved yet]

[EmperiO]

Hi all, I got a weird problem which I had never before.
When I use:

    $player=$_SESSION['player'];
    $sfield="SELECT * from km_sfield where name='$player'";
    $sfield2=mysql_query($sfield) or die(mysql_error());
    $sfield3=mysql_fetch_array($sfield2) or die(mysql_error());

Every code belows it like tables and stuff dont show up.

<?php
    $player=$_SESSION['player'];
    $sfield="SELECT * from km_sfield where name='$player'";
    $sfield2=mysql_query($sfield) or die(mysql_error());
    $sfield3=mysql_fetch_array($sfield2) or die(mysql_error());
function DisplayGrid($gridx,$gridy) {
    global $x, $y;

$bgcolor = 'background="http://conquerorsofsanvia.890m.com/background/grass.gif"';
//highlight current select grid coordinate
if ($gridx == $x && $gridy == $y) {
    $bgcolor = 'background="http://conquerorsofsanvia.890m.com/background/grass.gif"';
}
if ($gridx == $sfield3[x] && $gridy == $sfield3[y]) {
    $imgsrc = 'img src="http://conquerorsofsanvia.890m.com/images/bowman.png"';
} 

echo "<td width=\"50\" height=\"50\" $bgcolor align=center valign=bottom><a style='line-height:1em;width:75%;height:75%;display:block;' href=\"grid.php?xcord=$gridx&ycord=$gridy\"></a><br><font size=1 color='blue'>($gridx,$gridy)</font></td>";
}
[B]      print "<table class='maintable'><tr class='headline'><td><center>Deploy Soldiers</center></td></tr>";
      print "<tr class='mrw'><td>";
      print "Each unit contains a squad of 100 units from the same class.<br>";
      print "<form action='dplsoldiers.php' method='post'>";
      print "<SELECT NAME='class'>";
      print "<OPTION VALUE='Pikeman'>Pikeman";
      print "<OPTION VALUE='Archers'>Archers";
      print "<OPTION VALUE='Swordsman'>Swordsman";
      print "<OPTION VALUE='Cavalry'>Cavalry";
      print "</SELECT>";
      print "<input type='submit' name='submit' value='submit'></form>";
      print "</td></tr></table>";[/B]
?> 

If I use that code the part between fat doesn't shows.
I don't see what I am doing wrong and this is the first time that I get this error.

try setting you error reporting to show all errors,
maybe you have an error in your query & that stuck all other code.

beside that all the information in the function wouldnt show until you call it.

Nope no errors...

Someone got a solution

[sagee]

sorry,
i dont see any problem in the code .
what is not shown? the content of the function?
i still dont see where you call the function

[Betard]

EmperiO like everyone keeps saying you need to CALL that function... in the code provided you are not doing that....

you call your function by putting the below code wherever you want that functions results to appear:

DisplayGrid($gridx,$gridy);

ensuring that you have actually assigned values to $gridx and $gridy BEFORE calling the function so that they are passed along inside your function properly.

$player=$SESSION['player'];

$sfield2=mysql_query($sfield) or die(mysql_error());

$sfield3=mysql_fetch_array($sfield2) or die(mysql_error());
No that part of the code is okay, but the troubles start when I set this part of the code

    $player=$_SESSION['player'];
    $sfield="SELECT * from km_sfield where name='$player'";
    $sfield2=mysql_query($sfield) or die(mysql_error());  

    $sfield3=mysql_fetch_array($sfield2) or die(mysql_error());

Above the "call function" then the whole grid dissapears.

Sorry but I dont know what you are talking about.... in the code provided you never call the function... therefore the contents of the function are not processed, therefore the echo within the function is never generated.

You keep saying you are calling the function, and you aren't (atl east not in the code you are providing).

In your code you assign some variables/values, declare a function, and print out a select list... but you never call the function in order to process it.

This the whole code and I've fixed a little bit, but there is one more problem
you see the last part with the 'print "html code"'?
That one doesn't shows up now, I do not understand why?

[sagee]

i dont see any problem.
when i disable your db connection i see all the green table & all seems to work, therefore i again suggest for you to check you db connection

My db connection is okay, cause I got also other scripts on my page that use this db connection.
