Help to incorporate recaptcha to existing form

[R0CKY]

Hi

 

Im hoping I can get some help with this - as it is a big problem for me.

 

I am trying to add googles recaptcha code to my existing php page with a comment form...

 

This is the code I have to place before the submit button

 

<button

class="g-recaptcha"

data-sitekey="---deleted----"

data-callback="YourOnSubmitFn">

Submit

</button>

 

 

And This is my current form code from a php file (I've stripped out table layout tags for clarity)

 

 

<form action="{$settings.dburl}/index.php?act=comments&c=post&file={$file.file_id}" method="post">

   {#post_comment#}

   {#poster#

        <input type="text" name="subject" id="subject" size="40" maxlength="150" />

        <textarea name="comment" id="comment" rows="12" style="width: 95%"></textarea>

        <input type="submit" value="{#post_comment#}" onclick="postComment({$file.file_id}); return false;" />

</form>

 

I am confused about what I should replace the YourOnSubmitFn with?

 

Any help would be greatly appreciated.

Have you read the documentation? The callback must be a JavaScript function which is called when the user tries to solve the CAPTCHA and has a single parameter for the user's response (g-recaptcha-response). This response must be sent to the server along with the actual form data and then verified.

 

Your system for form submission is rather strange, though, so I cannot comment on how to actually implement the function.

This is the difficulty I have, I have no php or javascript experience and as you have spotted, I am using a rather old script. I usually muddle through with trial and error, however I am struggling now.

 

I'll figure it out though.

 

Thanks for the pointers.
