i have a php script that searches a column and prints it out.
the table appears fine in mozilla, but dont show in Explorer.
if i change the variable in the search script to a literal value, it
works fine.  i have tried alternatives, and it seems that the problem
is in the variable. here is the script:
any help appreciated.


<html lang="en">
<head> <title>Code Search</title>
<script TYPE="text/javascript" LANGUAGE="JavaScript"><!--
function setCampCode(code) {
    opener.campcode = code;
    opener.restart();
    self.close;
}
//--></SCRIPT>
</head>
<body BGCOLOR="white">
<?php //Database Connection - global
  $dbconnect = pg_connect("dbname=campus user=apache");
?>
<br>
<center>
<table width="90%" border="0" cellspacing="1" cellpadding="0"
bgcolor="green"><tbody><tr><td>
<table width="100%" border="0" cellspacing="1" cellpadding="8"
bgcolor="#f6f6f5"><tbody><tr><td>
<table width="70%" border=0 cellpadding=0 cellspacing=4>
<form name="campcode" method="post" action="<?php
print("$PHP_SELF");?>">

<tr><td>Search:</td><td><input type="text" name="code"></td>
<td><input type="submit" name="submit" value="Search"></td></tr>
</form></table>
</td></tr></tbody></table></td></tr></tbody></table> </center>
<br><br>
<?php
    //$code_query = $code;
    if($submit) {

    //THIS IS THE PROBLEM I THINK
    $qry_get_camp_codes = "select id, id, name from list where name
~* '$code'";
    $result = pg_exec ($dbconnect, $qry_get_camp_codes);
    if (!$result) {printf ("Error\n"); exit;}
    if (!pg_numrows($result)) { echo "<font color=\"red\" size=4>no
result</font>"; exit;}
    printf ("<center>
    ");
    printf ("<table cellpadding=4 cellspacing=1 border=1>
    ");
    printf ("<tr
bgcolor=\"lightblue\"><td><b>ID</b></td><td><b>College</b></td></tr>
    ");
    while($myrow = pg_fetch_row($result)) {

    printf ("<tr><td><a
href=\"javascript:setCampCode('%s')\">%s</a></td><td>%s</td></tr>"
    , $myrow[0], $myrow[1], $myrow[2]);
    }
    printf ("</table></center>
    ");
    }
pg_close($dbconnect);
?>

If it works in Mozilla but not in IE, your problem will most likely be
in the form or the javascript.

I recommend you use the phpinfo() function to display all of the PHP
variables (and other information) in the page and go from there.  When
you do that it will probably become obvious exactly what difference
there is between the two browsers.

The problem will have nothing to do with PostgreSQL, of course.

Cheers,
                    Andrew.

From your code, it looks like the table won't be printed if $submit is
not set (although your code is perhaps weak on checking the value of
that variable).

I have seen cases where IE will set the value of a submit button
variable differently if you hit <enter> within the form, than if you
click on the button with your mouse.

Remember, your comments accusation of "does/doesn't work in IE" is not
actually true - all of this code runs on the _server_ - not the client.
All that IE or Mozilla does is provide values for variables input to the
script: the script runs on the same server in both cases.

In any case in the phpinfo() I would look for differences in the value
of the "submit" variable.  Obviously differences in the value of the
"code" variable would have an effect as well, but are possibly less
likely.

You may want to lose the javascript too, to simplify debugging.  That
stuff _does_ run on the client, so may behave differently on Mozilla and
IE.  Personally I avoid DHTML like the plague (because it is so prone to
browser-specific problems) and so I don't know what your fragment is
supposed to achieve.

Cheers,
                    Andrew.

You could change that to:
      if ( "$code" != "" ) {

you are right! it seems IE set the value of the submit button variable
differently if you hit <enter> than if you click on the button. (i tried
clicking and it works fine)
 i modified the script as you suggested  from     if($submit) {
to    if( "$code" != "" ) {    and everything works fine now.
thanks again
