RE: [PHP] selecting from an array based on form content
$strandx is defined with code at the top of the page, as follows
$strandx = array('English' => array('Reading', 'Writing','Oral and Visual
Communication'),
'Mathematics' => array('Number Sense and Numeration', 'Measurement',
'Geometry and Spatial Sense','Patterning and Algebra','Data Management and
Probability'));

Where do you define the $strandx array? What is it's value?

RE: [PHP] selecting from an array based on form content
Thanks for the suggestion, John. When I implement your code, however, I get
an error saying
Warning: Invalid argument supplied for foreach() in
home/student/peter/public_html/week4.php on line 153
where line 153 is
foreach($strandx[$subject] as $strandy )
This is the code as I have it now:
switch($_POST['fsubject'])
{
case "English":
$subject = "English";
break;
case "Mathematics":
$subject = "Mathematics";
break;
}
Print "Now select the strands for Grade $grades:
$subject:";
print "";
print "$subject"; //this tells me that I have the correct value
foreach($strandx[$subject] as $strandy )
{
//print " ".$subject.".\n";
print " \n";
foreach( $strandy as $str )
{ print "";
checkbox("fstrand[]",$strandx,$str,0,0);
print "\n";
}
Any help would again be appreciated.

Since you already know $subjectx (English or Math), then just use that
value in your foreach() loop...
Foreach($strandx[$subjectx] as $strandy)
Where $subjectx would come from your form. Provide some validation
first.
So something like this:
//Many ways to do this, just validate
//whatever is coming from your form
//matches a key in $strandx
switch($_POST['subject'])
{
case "English"
$subject = "English"
break;
default:
$subject = "Mathematics";
break;
}
print " ".$subject.".\n";
foreach( $strandx[$subject] as $strandy )
{
print " \n";
asort($strandy ); // sorts the strands
foreach( $strandy as $str )
{
print "";
checkbox("fstrand[]",$subjectx,$str,0,0);
print "\n";
}
print " \n";
}
print "\n";

[PHP] selecting from an array based on form content
The following code loops through a multidimensional array, printing the
subject heading and then the strand:
foreach( $strandx as $subjectx=>$strandy )
{
print " ".$subjectx.".\n";
print " \n";
asort( $strandy ); // sorts the strands
foreach( $strandy as $str )
{ print "";
checkbox("fstrand[]",$subjectx,$str,0,0);
print "\n";
}
print " \n";
}
print "\n";
This is the array so far:
$strandx = array('English' => array('Reading', 'Writing','Oral and Visual
Communication'),
'Mathematics' => array('Number Sense and Numeration', 'Measurement',
'Geometry and Spatial Sense','Patterning and Algebra','Data Management and
Probability'));
I would like to limit the subject and strand being printed based on the
subject selected in a form. So, for example, if "English" is selected in the
form, only the subject name and the strands for English would be published.
Could someone please help me with the code for this.
Many thanks,
Peter Gumbrell
