Can't pass params to external php file

Question

I'm trying to make a simple contact form but I can't pass params from my module to external action="contact.php" file.

---

This is how I'm trying to get parameters to an external file:

$app = JFactory::getApplication('site');
$app->initialise();

$session = JFactory::getSession();

jimport( 'joomla.application.module.helper' );

$db = JFactory::getDBO();
$db->setQuery("SELECT params FROM #__modules WHERE module = 'mod_my_contact_form'");

$module = $db->loadObject();
$params = new JRegistry($module->params);

$contact_email = $params->get('myemail');

Result of the print_r('My e-mail: ' . $contact_email); stays empty:

My e-mail:

---

What might be the cause of this issue?

EDIT: I've tried that method but without any results:

$app = JFactory::getApplication('site');
$app->initialise();

jimport( 'joomla.application.module.helper' );
$module = JModuleHelper::getModule('mod_my_contact_form');

$registry = new JRegistry();
$params = $registry->loadString($module->params);

$contact_email = $params->get('myemail');

EDIT 2:

File structure:

mod_my_contact_form/
    tmpl/
       includes/
            contact.php
       default.php
     helper.php
     mod_my_contact_form.php
     mod_my_contact_form.xml

---

EDIT 3: I think the xml is built properly. This is how looks the param part:

...
    ...
    <fieldset name="contact_form" label="Contact Form">
        <field name="myemail" type="email" label="JGLOBAL_EMAIL" description="E-mail where you will receive all messages" size="30" class="inputbox" validate="email" />
    </fieldset>
   </fields>
  </config>
</extension>

Answer 1

By looking at updated xml file, I see only one issue that you haven't used <fields name="params"></fields> in config tag and hence your modparams object showing blank. Try below xml snippet for configs and check one more time the $module->params values.

<config>
<fields name="params">
<fieldset name="contact_form" label="Contact Form">
<field name="myemail" type="email" label="JGLOBAL_EMAIL" description="E-mail where you will receive all messages" size="30" class="inputbox" validate="email" />
</fieldset>
</fields>
</config>

Hope this will solve your problem :)

EDIT : By Looking at your comment I tried my self to develop module.Below are the steps -

1. I followed file structure given in question.

2. Here is My xml(mod_my_contact_form.xml)

   <?xml version="1.0" encoding="utf-8"?> <extension version="3.0" type="module" client ="site" method="upgrade"> <name>mod_my_contact_form</name> <files> <filename module="mod_my_contact_form">mod_my_contact_form.php</filename> <filename>index.html</filename> <folder>tmpl</folder> </files> <config> <fields name="params"> <fieldset name="contact_form" label="Contact Form"> <field name="myemail" type="email" label="JGLOBAL_EMAIL" description="E-mail where you will receive all messages" size="30" class="inputbox" validate="email" /> </fieldset> </fields> </config> </extension>

3. Here is Main PHP file of module(mod_my_contact_form.php)

   <?php // No direct access. defined('_JEXEC') or die(); echo "I am from Main File"; //Load default.php require JModuleHelper::getLayoutPath('mod_my_contact_form'); ?>

4. Here is My default.php

   <?php echo "<br>I am from Default file"; //Here I have loaded contact.php to send call there. require_once 'modules/mod_my_contact_form/tmpl/includes/contact.php'; ?>

5. I didn't do any different thing in contact.php, Just put down your code snippet.

   <?php echo "<br>I am from contact php"; $app = JFactory::getApplication('site'); $app->initialise(); jimport( 'joomla.application.module.helper' ); $module = JModuleHelper::getModule('mod_my_contact_form'); $registry = new JRegistry(); $params = $registry->loadString($module->params); $contact_email = $params->get('myemail'); echo "<br>Here is my params Email=> ".$contact_email; ?>

NOTE : I have just written code which need to go call into contact.php as we wanted to get params into contact.php file. Hence those required and all other stuff is used. So please use your code accordingly in respective files.
