Getting the values of dynamically created controls

[Arc]

Hi, I have a page wich has a number of checkboxes that are dynamically created and given individual numeric names. The user then checks certain ones and submits the form.

On the next page i need to see which ones were checked and get the name of the checkboxes.

I am trying a Foreach Loop but i can't figure out what keyword to use to get the control values. Heres my code.

Foreach($_GET as $chkBox){
  print $chkBox['value'];
}

How would i go about this?

Thanks!😃

Give the check boxes an aray name with your current numeric name as the index

<input type="checkbox" name=check[1]>
etc

You can then do

foreach ($_GET['check'] as $k->$v)

and the $k's will be your numeric index.

hth

hmm i'm not sure i follow you.. I name the checkboxes as arrays chk[0] chk[1] etc..

then on the next page

foreach ($_GET['chk'] as $k->$v) {

print chk[$k];

or 

print $_GET['chk'][$k];

or

?

}

I am also getting an error on the Foreach Line saying it's an invlaid argument.

This is the code on the page with the checkboxes...

 For ($Counter = 0; $Counter < count($TheImages); $Counter++){
Print "<img src=\"http://www.wildhorsesaloon.com/specialeventimages/$TheImages[$Counter]\"><br>";
Print"Current Image($TheImages[$Counter]) Delete:<input name=chk[$Counter] type=\"checkbox\" value=\"Checked\"><br><br>";
}

Sorry, should be => NOT -> (I hit wrong key)

foreach ($_GET['chk'] as $k=>$v) {

print "checkbox $k  has a value $v <br>";
}

In your code you forgot the quotes round the name (sometimes i can make a difference)

<input name=\"chk[$Counter]\" type=\"checkbox\" value=\"Checked\">

[Arc]

Hmm, i added the quotes around the name and added used the code you gave

foreach ($_GET['chk'] as $k=>$v) {
print "checkbox $k  has a value $v <br>";
}

and i still get the same error.

Warning: Invalid argument supplied for foreach()

any idea why?

Thanks!😃

Add a bit of debugging code

print '<pre>';
print_r ($_GET['chk']);
print '</pre>';

$_GET['chk'] should be an array.

[barand]

BTW only checked checkboxes are sent, so if there aren't any checked you wil get an error

if ($_GET['chk']) {

foreach .....

}

[Arc]

yah, i dunno man.. i tried the debugging code

print '<pre>';
print_r ($_GET['chk']);
print '</pre>';

and it doesnt print anything.

I am checking the checkboxes before submitting the form.

If i use this

foreach ($_GET['chk'] as $k=>$v) {
print "checkbox $k has a value $v <br>";
}

i get the invalid foreach error message...

Hmm...

[barand]

Are you 'POSTing the form?

[Arc]

yah i'm posting the form. If i manualy type one of the chkboxes names it gives me the value i.e print chk[0]; it prints out "Checked" if its checked.

But when i try to use your code i just get nothing or errors...

[barand]

Then do you get anything when you change $GET to $POST ?
