Unable to retrieve POST data from registration form

[halben]

Hi, I'm running into an issue retrieve data values from a registration submission form. The form is using a POST method Please see code below.

 

More codes above, just a small snippet ...

<div id="s2member-pro-paypal-registration-form-email-div" class="s2member-pro-paypal-form-div s2member-pro-paypal-registration-form-div s2member-pro-paypal-form-email-div s2member-pro-paypal-registration-form-email-div">
<label for="s2member-pro-paypal-registration-email" id="s2member-pro-paypal-registration-form-email-label" class="s2member-pro-paypal-form-email-label s2member-pro-paypal-registration-form-email-label">
<span><?php echo _x ("Email Address", "s2member-front", "s2member"); ?> </span><span class="red-asterik">∗</span><br />
</label>
<input type="text" aria-required="true" data-expected="email" maxlength="100" autocomplete="off" name="s2member_pro_paypal_registration[email]" id="s2member-pro-paypal-registration-email" class="s2member-pro-paypal-email s2member-pro-paypal-registration-email" value="%%email_value%%" tabindex="40" />
</div> 

...

<div id="s2member-pro-paypal-registration-form-submit-div" class="s2member-pro-paypal-form-div s2member-pro-paypal-registration-form-div s2member-pro-paypal-form-submit-div s2member-pro-paypal-registration-form-submit-div">
%%hidden_inputs%% <!-- Auto-filled by the s2Member software. Do NOT remove this under any circumstance. -->
<input type="submit" name="registration_submit" id="s2member-pro-paypal-registration-submit" class="s2member-pro-paypal-submit s2member-pro-paypal-registration-submit" value="<?php echo esc_attr (_x ("Register", "s2member-front", "s2member")); ?>" tabindex="400" />
</div>
<div style="clear:both;"></div>
</div>

For this example, I have the following:

// Store POST data into a variable
$email = esc_attr($_POST['s2member_pro_paypal_registration[email]']);

// Detect Submission
if (!isset($_POST['registration_submit'])){
    // Do nothing
} else {
    // Check it
    var_dump($email);
}

This seems like it's correct but I wasn't able to retrieve the POST data and var_dump() was returning an empty string. Does anyone know why and should I post up more codes for more assistance?

 

Thank you,

Hal

$_POST['s2member_pro_paypal_registration'] should be    $_POST['s2member_pro_paypal_registration']['email']

<input type="text" maxlength="100" autocomplete="off" value="" name="s2member_pro_paypal_registration[custom_fields][company_name]" id="s2member-pro-paypal-registration-custom-reg-field-company-name" aria-required="true" tabindex="105" data-expected="alphanumerics-5" class="s2member-pro-paypal-custom-reg-field-company-name s2member-pro-paypal-registration-custom-reg-field-company-name">

And the code above should be:

$_POST['s2member_pro_paypal_registration[custom_fields][company_name]'];  -> $_POST['s2member_pro_paypal_registration']['custom_fields']['company_name'];

Can you please give me a quick explanation?

And the code above should be:

$_POST['s2member_pro_paypal_registration[custom_fields][company_name]'];  -> $_POST['s2member_pro_paypal_registration']['custom_fields']['company_name'];

Yes.

 

When you name a fields like foo[bar].The the $_POST becomes a multidimensional array. You can see how the $_POST is formatted using

printf('<pre>%s</pre>', print_r($_POST, true));
