Question : Send multiple checkbox to a contact page

i have a page with a list of documents obtained from a mysql query. This list provides a checkbox (value=id of document) per document, and, what i need is to create a button that send the selected document id's (one checkbox correspond to 1 id) to a new page (a contact form page) that will contain a textbox (textarea) with the selected items concatenated in it.

For example,

- supose the list has 7 documents (so 7 id's)
- supose we selected 4 documents (4 checkboxes from those 7)
- after clicking on a "Submit" button the result should be going to the next page and displaying a textbox (in a contact page) with the concatenated "http://localhost/open/id_number" string.

I currently have achieved displaying the documents in the list and add the checkbox asociated to its id_number in it.

Answer : Send multiple checkbox to a contact page

You are sending the form data to a file called send.php when you click on the submit button.

In the send.php file you can create the delimited string for the check ID's with the code I posted earlier.

<?php
if (isset($_POST['DocID'])) {
   $SelectedDocuments = implode(",", $_POST['DocID']);
}
?>

In the send.php script you now have a variable called $SelectedDocuments.

To put that in the textarea, you will need to echo it into the form. Take a look at the code below to see what I mean.


1:

<td><textarea name="detail" cols="50" rows="4" id="detail"><?=$SelectedDocuments?></textarea></td>
