Get check box value if checked

I'm building a form using HTML with JQuery mobile so that the form can be used on mobile devices.

I have the form exporting to CSV via email. However the write to the CSV file doesn't occur when Checkboxes aren't checked.

Can I use functions in jQuery to pull the values from the checked checkboxes, using the values from the label, and to mark the unchecked boxes as Null or as a Space so that when I import them into Excel it notices the values aren't checked?

<label for=question4 class=input> 4. What language (s) are you currently using? </label>

<fieldset data-role=controlgroup>

    <legend>Multi select:</legend>

    <input type=checkbox name=checkbox-1 id=checkbox-1 class=custom value=english/>

    <label for=checkbox-1> English</label>

    <input type=checkbox name=checkbox-2 id=checkbox-2 class=custom />

    <label for=checkbox-2>French</label>

    <input type=checkbox name=checkbox-3 id=checkbox-3 class=custom />

    <label for=checkbox-3>Spanish</label>

    <input type=checkbox name=checkbox-4 id=checkbox-4 class=custom />

    <label for=checkbox-4>Brazilian Portuguese</label>

    <input type=checkbox name=checkbox-5 id=checkbox-5 class=custom />

    <label for=checkbox-5>Italian</label>

    <input type=checkbox name=checkbox-6 id=checkbox-6 class=custom />

    <label for=checkbox-6>German</label>

    <input type=checkbox name=checkbox-7 id=checkbox-7 class=custom />

    <label for=checkbox-7>Japanese</label>

</fieldset>

</br>

if there isn't a way to do in JQuery, what about in PHP? Since I'm using PHP to populate the CSV file.

Would it be some form of a if statement that says:

if checkbox = yes then pull value from <label>

Change your HTML and give a name attribute to all your checkboxes, like so:

<form action= method=post>

<label for=question4 class=input> 4. What language (s) are you currently using? </label>

<fieldset data-role=controlgroup>

<legend>Multi select:</legend>

<input type=checkbox name=checkbox[] id=checkbox-1 class=custom value=english/>

<label for=checkbox-1> English</label>

<input type=checkbox name=checkbox[] id=checkbox-2 class=custom />

<label for=checkbox-2>French</label>

<input type=checkbox name=checkbox[] id=checkbox-3 class=custom />

<label for=checkbox-3>Spanish</label>

<input type=checkbox name=checkbox[] id=checkbox-4 class=custom />

<label for=checkbox-4>Brazilian Portuguese</label>

<input type=checkbox name=checkbox[] id=checkbox-5 class=custom />

<label for=checkbox-5>Italian</label>

<input type=checkbox name=checkbox[] id=checkbox-6 class=custom />

<label for=checkbox-6>German</label>

<input type=checkbox name=checkbox[] id=checkbox-7 class=custom />

<label for=checkbox-7>Japanese</label>

</fieldset>

</br>

<input type=submit name=submit>

</form>

Once the form has been submitted, the name attributes will be passed as array and they'll be accessible using the same variable. Now, you can use isset() to check if a particular item was set:

if(isset($_POST['checkbox'])) {

  print_r($_POST); //print all checked elements

}

If you want to get the number of checkboxes that were checked, you can use count():

$number = count($_POST['checkbox']);

Note: currently, only the first element has a value attribute. You'll have to add it for the rest of the checkboxes for it to work properly.

Hope this helps!
