do I have to cast values from text boxes into ints?
If so, it's wierd, because I have taken the values from text inputs
before
and just put them into insert string statements for mysql. It turned
them
into ints just fine.
I use the following code to MAKE a table of input boxes on the screen,
and the exact
same thing to READ it after submission.
the value $$vent_flow_identifier comes back with the entered value, but
as a string.
and example of the names of the INPUT boxes out and comes back is:
Vent1MinFlow
Vent1MaxFlow
Vent2FixedFlow
The '1' and the 'xxxFlow' are from columns in a set of tables.
<code>
//$room_vent_values are a two colomn result in an array of length2
arrays
//for the vents in a room, numbered 1..vents_in_the_room
//functions of vents are supply, return, exhaust
//A supply vent has a MaxFlow, and a MinFlow, Returns and Exhausts have
a Fixed Flow
//Those allowable flows are in $allowed_ventflowtype_values, indexed by
the
//Vent functionID
while ( list( $this_vent_num, $this_vent_functionID) = each(
$room_vent_values )){
$alt_bgcolor="";
if ( $this_vent_num % 2 ) $alt_bgcolor = "bgcolor=\"#E69B9F\"";
// causes alternating colors in odd/even vent numbers
echo("<br>\n");
reset( $allowed_ventflowtype_values );
while ( $vent_function_flow_array = each(
$allowed_ventflowtype_values )){
$flow_type_vent_functionID = $vent_function_flow_array[1][0];
$flow_type = $vent_function_flow_array[1][1];
if ( $this_vent_functionID == $flow_type_vent_functionID ){
$vent_function_name =
$vent_function_values[$this_vent_functionID];
$vent_flow_identifier = "Vent" . $this_vent_num .
$flow_type;
//start of row for output table, only the <input ...> is
entered by user
// the rest is from a database retrieval and fill in.
$flow_entry_table .= " <tr $alt_bgcolor>\n";
$flow_entry_table .= " <td
align=\"center\"> $this_vent_num </td>\n";
$flow_entry_table .= " <td
align=\"center\"> $vent_function_name </td>\n";
$flow_entry_table .= " <td
align=\"center\"> $flow_type </td>\n";
$flow_entry_table .= " <td align=\"center\"> <INPUT
type=\"text\" name =\"$vent_flow_identifier\"
size=\"5\"> </td>\n";
$flow_entry_table .= " </tr>\n";
}
}
}
</end_code>
The form that this makes, and later tests the results of looks like:

<form name="Entry"
action="FlowReadingsEntryTable.php"
