This is probably very easy but im also very new to php. Im looking for a way that i can have checkboxes on a form that can be passed via the submit button to a php file that generates a Header locate based on the values.

for example

Apples X Pears Oranges X

would result in the output php file doing开发者_开发问答 a header("Location:url.com/Apples+Oranges");

Im haivng difficulty working out how to get the checkbox values as a string and secondly in doing this above the header causes the header to fail for obvious reasons so I guess i have to use some output buffer?

Thanks!

Basically you just get the post variables and redirect before any other output is made:

<?php 
if(((bool) $_POST)){
    $url = 'http://url.com/';
    $url .= implode('+',$_POST['fruit']);
    $url .= $_POST['fruittext'];
    header("Location: ".$url);
}
?>

<body>
<form action="" method="post">
    <input value="Apples"           type="checkbox" name="fruit[]" />
    <input value="Pears"            type="checkbox" name="fruit[]" />
    <input value="Oranges"          type="checkbox" name="fruit[]" />
    <input value="magicmushrooms"   type="checkbox" name="fruit[]" />
    <textarea name="fruittext"></textarea>
    <input type="submit" />
</form>
</body>
</html>

Assuming that there are no other form elements being submitted along with those checkboxes, and the form is being submitted via POST:

 $string = url_encode(implode(',', array_keys($_POST)));
 header("Location: url/$string");

If there are other values and you only want the checkboxes, you'll have to specify which form fields should be treated this way, rather than just grabbing everything.
