Hello all,

Hopefully you will find this an easy one. I am giving users a selection of checkboxes in a form that they can select. I want to collect the information from the responses to store in a database.

Here is some code which seperates out the reasons given and lists them to the screen:

if(isset($_POST['reasons'])) {
foreach(($_POST['reasons']) as $reasongiven => $Arrayitem) {
echo "$Arrayitem <br>";
}

Can anyone please tell me how to also set a new variable to each item that is being echoed to the screen?

I want to echo the item, but also set a variable to contain this information so that I can then pass the variables into a database and send them via email.

Thank you for helping

Why would you want to create a new variable for each value? The information is already in an array($_POST['reasons']), so you can just use that to insert into a db.

That only gives me the last variable entered though - I need to collect all of them...

I'm not sure I understand your comment. Do you have the checkboxes in an array--meaning is the name the same on each checkbox with '[]' at the end? If not, this is what you are looking to do. Something like this in the form:

Just because<input type='checkbox' name='reasons[]' value='just because' /><br />
No reason<input type='checkbox' name='reasons[]' value='none' />

Yes they all have the name reasons[] and there are 14 choices that can be selected...

...So then the info is in an array and you don't need new variables to achieve what you want. Look at what this shows you:

echo '<pre>';
[url=http://us3.php.net/print_r]print_r[/url]($_POST['reasons']);
echo '</pre>';

Hi cazgh

eelixduppy is right and you could get the whole array into the DB directly from the $_POST array.

The most obvious way (to me) is to use the implode() function to create an SQL friendly list of comma separated values under 1 new variable name.

So something like : -

if(isset($_POST['reasons'])) {
$imploded = implode(",",$_POST['reasons'])
}

this would create a variable called $imploded with a value of 'value1, value2, value3, value4' which could then be used as a part of an SQL statement - of course, you still need to construct the rest of the SQL statement to make use of $imploded ;-)

Hope this helps, Rolf

OK - but still not sure how to send them through via email - sorry, you'll have to excuse me as I am a bit thick, and even worse on Friday's as my brain is generally mashed by this time of the week...

>>>send them through via email

For that, you can refer to this thread on Basics of Submitting and Emailing Forms with PHP [webmasterworld.com] taken from our Library [webmasterworld.com]. Good luck ;)
