[PHP] Can't get this code to work...
Sorry for the vague Subject, but I have this code that looks fine to me.
There's some logical error, because I can't get to the second if statement,
although when I echo "\$".$cb[$i] I get $checkboxName. If I hard code
$checkboxName it will work though. Anyone know why? TIA!
$num_fields= 8 ;//the number of fields on the form!
$cb=array("Name", "Address", "State", "Zip", "Phone", "Email", "Comments",
"Fax");
for($i=0; $i<$num_fields; $i++){
if ("\$".$cb[$i] !="")
{
// CAN GET HERE
if ("\$checkbox".$cb[$i]=="validate")
{echo"can NOT get here";// HINT, HINT
$form_write_msg .=
'if (!$cb[$i])
{$error_msg.="Your " . $cb[$i] . " .\n";}
if ("\$".$cb[$i]){
$msg.="\$".$cb[$i].": \t" . $cb[$i] . " . \n";}
'
;}elseif("\$checkbox".$cb[$i]=="no")
{$form_write_msg.=
'if ("\$".$cb[$i]){
$msg.=$cb[$i] .": \t " .$cb[$i]. " . \n";}
'
;}
;}

Because you're making a string "$checkboxName" Of course it doesn't
equal "validate"
If you want to evaluate the variable $checkboxName, you need to write:
$var = "checkbox$cb[$i]";
if ($$var == 'validate')
But, of course, that assumes you actually set the name of your checkbox
to "checkboxName" and the value of that checkbox to "validate"

Pardon my following up to myself, but I figured it'd be a good idea to
do so. I was initially going to suggest your method of coding seems
quite wacky. Then, I figured, hey, let them do what they want. Now,
I've thought better of it. A far simpler way to achieve what it seems
you're trying to do is to use an array in the first place.
Then in your receiving code, you could just do
if ($checkbox['Name'] == 'validate') {
Or, if you want to loop through each item, as you were in your original
code:
while ( list($Key,$Val) = each($checkbox) ) {
if ($Val = 'validate) {
$msg .= "$Key : $Val\n";
# or whatever it was you were trying to do...
}
}
WAY cleaner and WAY more flexible. Now you can add new items to the
form without having to name them in your $cb[] array.
Also, FYI, there was no need to set the array using $cb[$i]. Just
doing something like
$cb[] = 'some value'; works just fine, with the key being
automatically numbered/incremented, starting at 0.
Enjoy,

Dan, Really, thanks for the help. Yeah, as you know I'm not experienced near enough with PHP. Maybe you could provide me with an e-mail and prices for consultation(I suppose this is what 'Analysis & Solutions' does?)
