I am a newbie poster to the site and have just started using php and mysql - have been painstakingly getting dummy site set up which sells CDs, I have searched this site to find the answer to my prob; which is:
On the catalogue page - user or guest can search the catalogue using text field, but I also want the option of choosing from 4 checkboxes (they can all be checked) for type of music e.g. C&W, pop, rap, blues. Also, they can input year of release and price (but I haven't got around to how to do that yet! - maybe another text field or ).... basically HELP! I've been going round in circles trying to figure it out as I'm new .... any help gratefully received!
Thanks; OM
When handling checkboxes, it is very similar to handling other post data, with one exception. Here is a sample form:
<form action="page.php" method="post">
one<input type="checkbox" value="1" [b]name="numbers[]"[/b] />
two<input type="checkbox" value="2" [b]name="numbers[]"[/b] />
three<input type="checkbox" value="3" [b]name="numbers[]"[/b] />
<input type="submit" />
</form>
Notice here how I have defined the name attribute with the two brackets at the end. This signifies that these values are going to be arrays.
And now here is
page.php
<?php
#
$checkboxes = [url=http://us3.php.net/manual/en/reserved.variables.php#reserved.variables.post]$_POST[/url]['numbers']; #this is the array from the form (only selected values)
echo '<pre>';
[url=http://www.php.net/print-r]print_r[/url]($checkboxes);
echo '</pre>';
#
?>
You'll see here that it will print out only those that have been selected. Now from here, you can use various array functions [us3.php.net] to handle the data accordingly.
Also, if it will help, here's the documentation on the form element [w3.org]. Should provide you with some detailed information ;)
Good luck!
Also, they can input year of release and price (but I haven't got around to how to do that yet! - maybe another text field or )
A text field would work, but you could also use a SELECT [w3.org] element, which, I believe, would be better in this case. Handling a select is similar to the other input types.
