Taking multiple values from checkboxes and passing them to the header on "submit"
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.
