RE: [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 lib.$subjectx./b.br /\n;
print ul\n;
asort( $strandy ); // sorts the strands
foreach( $strandy as $str )
{ print li;
checkbox(fstrand[],$subjectx,$str,0,0);
print /li\n;
}
print /ul\n;
}
print /ol\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.
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:
$subject = Mathematics;
break;
}
print ollib.$subject./b.br /\n;
foreach( $strandx[$subject] as $strandy )
{
print ul\n;
asort($strandy ); // sorts the strands
foreach( $strandy as $str )
{
print li;
checkbox(fstrand[],$subjectx,$str,0,0);
print /li\n;
}
print /ul\n;
}
print /li/ol\n;

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 h4Now select the strands for Grade $grades:
$subject:/h4/td/trtrtd;
print td;
print $subject; //this tells me that I have the correct value
foreach($strandx[$subject] as $strandy )
{
//print lib.$subject./b.br /\n;
print ul\n;
foreach( $strandy as $str )
{ print li;
checkbox(fstrand[],$strandx,$str,0,0);
print /li\n;
}
Any help would again be appreciated.

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

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'));
