We built our own simple Plugin, which asks the user some data like height and weight.
We implemented the Shortcut in the Unit from a Course.
The Result is a Error Message like "0" or "This Course can not be taken. Contact Administrator.".
If we paste the shortcode into the start page, it works fine.
The Form we programmed only contains a simple php/html Form with "$_Post" and later a connection to the user database of WordPress with update_user_meta.
(Sometimes it worked, but then only in the last unit of the course)
Please help :)
@food-interactive
This error message only appear when the cookie is not set. When you click on any unit it should set a cookie so that the id will be fetched from there
Please debug your plugin in this way
Hello Diana,
sorry, but i don't understand your answer.
We only want to get some Userdata with a simple Form. Why we need cookies? Why the unit interrupts the transfer to the database and outputs "0", or the Errormessage.
Again: Our Shortcode (transfer / saving to the wp-database) works, if we put it to the start page.
I read in the net, some people who deal with the same problem and wrote something about Ajax?
If its only working with cookies, can you then send some code-example for our plugin?
We need this Form of our Plugin, else we have no usage for wplms.
I hope you can help.
Greetings from Food-interactive Team
@Food-Interactive,
Can you please share a recording how it works?
I cannot share proper code for your plugin because it is not a part of theme support but after checking your screen recording I can help you if possible
I will try my best
Here is the function, wich we include with our shortcode:
function anamnese_form()
{
echo '';
echo ' . esc_url( $_SERVER['REQUEST_URI'] ) . '" method="post">';
echo '';
echo 'Anamnese';
echo 'Geschlecht :männlich';
echo 'weiblich';
echo 'Alter (Jahre) :';
echo 'Größe (cm):';
echo 'Körpergewicht (kg):';
echo 'Tägliche Bewegung :sitzend/liegend';
echo 'wenig körperlich aktiv';
echo 'sitzend/zeitw. gehend stehend';
echo 'überw. gehend / stehende Tätigk.';
echo 'körperlich anstrengende Tätigk.';
echo '';
echo '';
echo '';
if ( isset($_POST['submitknopf']))
{
$userr = get_current_user_id();
$geburtstag = $_POST['alter'];
$größe = $_POST['cm'];
$kilo = $_POST['kg'];
$geschlecht = $_POST['geschlecht'];
$bewegung_faktor = $_POST['faktor'];
$anamnese_array = array ( 'alter' => $geburtstag,
'cm' => $größe,
'kg' => $kilo,
'geschlecht' => $geschlecht,
'faktor' => $bewegung_faktor,
);
update_user_meta($userr,'anamnese',$anamnese_array);
}
}
</div>
With this Code we call the function:
function anamnese_shortcode()
{
ob_start();
if ( is_user_logged_in() )
{
anamnese_form();
}
else
{
echo 'Bitte einloggen...';
}
return ob_get_clean();
}
</div>
Please tell me why it don't work in a unit of a course.
Greetings from Food-interactive Team
In the above code you are updating in database table if someone clicks that button(the data which you are fetching from $_POST method
And you have two conditions if user is logged in then call this function anamnese_form
otherwise show a text
But in anamnese_form you are not fetching course_id . This is the issue I can see as far as now
ok, but why our simple code is working in other pages from the wplms theme, but not in a unit?
Why we have to deal with a course id?
Can't this be fixed by the unit/course settings?
If it is not possible to fix this in a simple way, please tell me how to implement the course_id
Because on other pages you don't need any data but if you will add this in course unit. Then the function works in this way in course units
Whenever someone clicks on the "Course button" and enroll in course there you will see button back to course
We usse POST Method to fetch the course units which is connected to that course and all related stuff and cookie for course id set. In case, someone wants to exit from course he clicks on "Back To Course" and he exits from course(the course id fetched from the saved cookie)
This is the issue that you are saving user data in database, but it is expecting course id as well due to this error appear that this course cannot be taken
How can I fix this?
If the only solution is to handle with cookies, please give me a code example, or tell me how i can access to the saved cookie, and rewrite the cookie with what?
Or is it possible to end your $_POST, before i start my code?
Meaning: Can I programm, saying the "Back to Course Button" is beeing pressed and afterwards my Form is executing?
With this action hook
wplms_course_start_after_timeline
you can actually redirect "Back to Course" button to any other page
And because you are redirecting back to course button to any page. So I don't think So you will need any id
But if you are adding something on course status page then the code should be like this
If(!empty($_POST['course_id'])){
$course_id = $_POST['course_id'];
}else{
$course_id = $_COOKIE['course_id'];
}
hey cool, sounds like a solution :)
I would implement it like this :
<span style="display: inline !important; float: none; background-color: #ffffff; color: #4b4d4d; font-family: 'Lato'; font-size: 14px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-decoration: none; text-indent: 0px; text-transform: none; -webkit-text-stroke-width: 0px; white-space: normal; word-spacing: 0px;"><span style="color: #001000; font-family: Georgia,"Times New Roman","Bitstream Charter",Times,serif;">function anamnese_shortcode()
{
ob_start();
if ( is_user_logged_in() )
{
if(!empty($_POST['course_id']))
{
$course_id = $_POST['course_id'];
}
else
{
$course_id = $_COOKIE['course_id'];
}
anamnese_form();
}
else
{
echo 'Bitte einloggen...';
}
return ob_get_clean();
}</span></span>
Is this correct?
oh sorry, I copied from my editor :-S
Please read the code beginning from "{ ob_start()"
Yes, Let me explain my code snippet
It will fetch the course id if someone clicks on a course button with $_POST Method
Else it will look in saved cookies and fetch the course id from there
I can't help you more than that
I hope this will work for you
Sorry, but it didn't work.
We tried the Form with only one Unit in a Course and it works fine.
If we put another Unit behind, and test the first unit again, there comes the error message : "This Course can not be taken. Contact Administrator."
Please ask one of your Colleagues for help.
It can't be a big deal!?
@Food-Interactive,
Other colleagues will also ask for your site credentials because without checking in actual scenario we can't just provide the code randomly.
It works with one unit which means the code is correct.
Please do check the course status page and how we are fetching the course id and loading the connected unit id content of that course.
I already mentioned in which file to check
.
