html forms and variables

[Anon]

The problem:

I'm building a set of checkboxes from an array and I want to be able to make them "sticky" so that when a box (or 2 or 3...) is/are checked and the form is submitted, the page will reload with all of the checkboxes again, and the boxes that were previously checked, will remain checked.

Any help would be greatly appreciated.

I think I'm somewhat close, but just can't seem to get it to work:

$count=count($categories);
for ($i=0; $i<$count; $i++) {

print ($categories[$i] . "<br>");

}

print ("<form method='get' name='form1'>");

$switchCategory = array("a" => "Cat1",
"b" => "Cat2",
"c" => "Cat3",
"d" => "Cat4",
"e" => "Cat5",
"f" => "Cat6",
"g" => "Cat7",
"h" => "Cat8");

reset ($switchCategory);
while (list ($key, $value) = each ($switchCategory)) {

if ($key == $categories[$i]) { print ("<input type='checkbox' name='categories[]' value='" . $key . "' checked>" . $value . "<br>"); }

else { print ("<input type='checkbox' name='categories[]' value='" . $key . "'>" . $value . "<br>"); }

}
print ("<input type='submit' value='submit'>");
print ("</form>");

thanks

I see your problem:

this ->
<input .... name='categories[]' ...>

is not going to do what you expect it to do.
Assign the key to the name like this

print ("<input type='checkbox' name='categories" . $key . "' value='doesntmatter'>" . $value . "<br>"

now you can check if that checkbox was checked (djesh) like this:

$cat = "categories" . $key;

if(!empty($$cat)) {
<write checked checkbox>
} else {
<write unchecked checkbox>
}

notice the use of the double dolar signs.

good luck!
