Form text field problems

The_Chancer

I have a slight problem with not being able to correctly get the name of a text field from an HTML page. The code is as follows:

<?php

$query="SELECT room_name,theatre,u_shape,hollow_square,classroom,boardroom,cabaret,reception,dinner_dance,banquet FROM conf_rooms WHERE hotel_id='$hotel'";
$result=do_query($query);
print("<html><head><title>List Conference Rooms for hotel</title>
<link rel=\"stylesheet\" href=\"../../ccs.css\" type=\"text/css\">
<script language=\"Javascript1.2\">
<!--
function goNow(target)
{
if (target==1){
document.form1.action=\"chngrooms.php?page=2&store=yes&what=caps\";
document.form1.submit();
}
if (target==2){
document.form2.action=\"chngrooms.php?page=2&store=yes&what=dimensions\";
document.form2.submit();
}
if (target==3){
document.form3.action=\"chngrooms.php?page=2&store=yes&what=heights\";
document.form3.submit();
}
}
function room(roomname,targ)
{
if (targ==1) document.form1.roomselect.value=roomname;
if (targ==2) document.form2.roomselect.value=roomname;
if (targ==3) document.form3.roomselect.value=roomname;
}

function check()
{
	var sure= confirm(\"Do you really want to update figures ?\");
	if (sure== true) 
	{
		return true;
	}
	else return false
}
warning = \"Coding by Andrew Chance\";

bV  = parseInt(navigator.appVersion)
bNS = navigator.appName==\"Netscape\"
bIE = navigator.appName==\"Microsoft Internet Explorer\"

function noclick(e) {
   if (bNS && e.which > 1){
      alert(warning)
      return false
   } else if (bIE && (event.button >1)) {
     alert(warning)
     return false;
   }
}

document.onmousedown = noclick;
if (document.layers) window.captureEvents(Event.MOUSEDOWN);
if (bNS && bV<5) window.onmousedown = noclick;

<----file snipped----->

As you can see the input name for text are dynamically named, and when the data is passed from the database out to the page they are named with the specific room name for the values shown.
All goes well up to here.
Then when the link is clicked, the javascript bits kick in and the correct room name is passed and can be read by using

<? echo $roomselect ?>

But if you wanted the value of the text using

<? echo $theatre$roomselect ?>

doesn't work for obvious reasons ($theatre='' and $roomselect='a room name') and gives the value of just $roomselect.
The data does work as

<? echo $theatreroomname ?>

gives a true value of the information in the form.

So.. my question is this - how can you get $theatre$roomselect to give the proper value ?

Any ideas ?

bernouli

use this

<? echo $theatre.$roomselect ?>

The_Chancer

I have tried that one, all that comes out is..

.roomname

bernouli

change all the function into

e.g you have

function goNow(target) ,
change into

function goNow($target)
and
if (target==1)
into if ($target==1)

youu must enter $ infront of each variable

The_Chancer

That part of the code is fairly irrelavent to the topic question. But it works fine. If you put a $ in front of the variables in Javascript it will make an error.

The only problem is with getting the name of the text field, no other part of the code.

bernouli

ups sorry, i thought it was php codes 🙂

try to put this att all lines

<td align=\"center\"><input type=\"text\" name=\"$theatre.$room_name\" size=\"3\" maxlength=\"10\" class=\"lighttextbox\" value=\"$theatre\"></td>

The_Chancer

No worries,
Tried the

<input type=text name=\"theatre.$room_name\" >

Code but no success... I have been trying this though

$str=array('$theatre',$roomselect);
$string=implode("",$str);

which gives the correct answer but it doesn't recognise it and just puts it out as a string, and doesn't pull the data.

Any ideas on how to change that ? (or is it a spanner in the works ?)

bernouli

its not quit right

you must put the $ in front od the theatre

The_Chancer

OK, so

<input type=text name=\"$theatre.$room_name\">

Gives me a name which would be a combination of two variables $theatre and $room_name. $theatre is set by the SELECT statement from my MSSQL database and is a numerical figure, and $room_name is (obviously) the name of the room.

When this is passed through and I use

<? echo $theatre.$roomselect ?>

All I get is still .roomname

bernouli

hmm, that seems to be that javascript cant read the variable returned from formular, all you have to do is to make the javascript can do this, but i dont know how to do that, sorry

The_Chancer

No worries, going to have to think of some sort of workaround...

Thanks for trying though

The_Chancer

Found the answer...

Use the following:

$number=${theatre_.$roomname};
echo $number;

and it all works perfectly...
