for a recent project, I needed an easily adaptable form, with a lot of
different, often changing elements, so I came up with the following
function (amongst others!):
// dropdown boxes
function dropdown($fieldname, $currentvalue='', $onchange='') {
$var_val = $fieldname . '_val';
$var_disp = $fieldname . '_disp';
global ${$var_val}, ${$var_disp};
if($onchange <> '') $onchange = 'ONCHANGE="' . $onchange . '"';
echo('<SELECT NAME="' . $fieldname . '" ' . $onchange. '>');
for($loopy=1; $loopy<=sizeof(${$var_val}); $loopy++) {
echo('<OPTION VALUE="' . ${$var_val}[$loopy] . '"');
if($currentvalue == ${$var_val}[$loopy]) echo(' SELECTED');
echo('>' . ${$var_disp}[$loopy]);
}
echo('</SELECT>');
}
I have an include file with the options for each form element -
meaning options can be added or removed easily - an example is:
// Sex
$Sex_val[1] = 'M';
$Sex_disp[1] = 'Male';
$Sex_val[2] = 'F';
$Sex_disp[2] = 'Female';
The function would be called by:
// create dropdown
dropdown('Sex');
// create dropdown, select a matching value
dropdown('Sex',$current_sex);
// create dropdown, select a matching value and run a javascript
function when element is changed
dropdown('Sex',$current_sex, 'checkSex()');
