Use Contact Form 7 to validate and send a custom-made form

Question

I've fairly used CF7 but I haven't found a work-around or a module to be able to dinamically build a form and then use the CF7 plugin to validate and send it.

In my case, I am using custom fields to build a form in a template. How can I send that template as if it were a CF7 form?

EDIT: I am adding a bounty, requirement for correct answer is how to use CF7's validation, ajax send and locale (with WPML) functions in a partly or completely PHP-generated form. The form I want to send is here.

<form>
    <table>
        <thead>
            <tr>
                <th>Name</th>
                <th>Description</th>
                <th>Quantity</th>
            </tr>
        </thead>
        <tbody>
            <?php
            $products = get_field('products'); 
            foreach($products as $product):
                $id = $product['id'];
                ?>
                <tr>
                    <td class="name"><?=$product['name'];?></td>
                    <td class="description"><?=$product['description'];?></td>
                    <td class="quantity">
                        <input type="text" size="4" name="quantity-<?=$id;?>" id="quantity-<?=$id;?>" />
                    </td>
                </tr>
                <?php
            endforeach;
            ?>
        </tbody>
    </table>
    <fieldset>
        <ul>
          <li>
            <label for="your-name"><?=__('Your Name');?></label>
            <input name="your-name" type="text" />
          </li>
          <li>
            <label for="your-email"><?=__('Your Email');?></label>
            <input name="your-email" type="text" />
          </li>
          <li>
            <input type="submit" value="<?=__('Send');?>" />
          </li>
        </ul>
    </fieldset>
</form>

Answer 1

Well I guess what you should to is quite simple include the scripts for cf7 and then make sure the selectors inside the script works for yours aswell. start of with creating a div that wraps ur form give it the class wpcf7, second of all give ur submit button the class wpcf7-submit, and depending on what your validating you give the diffrent inputs diffrent classes and on top of that you have to create some extra divs so it'll be able to show the error messages

<div class="wpcf7-response-output wpcf7-display-none"></div>

for example to validate an email adress u give it the class

wpcf7-validates-as-email

When you've done this things and it still doesn't work, it means that some selector failed, and you can easy track which one by opening the javascript console in whatever brower you use and check for the error

If I was you I would use the Gravity Forms plugin, it will save you a lot of problems rather than creating a custom form.
