This is my first php script ever and I have googled a lot to try to get the script to work.

What I am trying to accomplish is the callback URL. I first tried to create it in WordPress, which was also a first, and now try with php code.
Here is what I try to accomplish:
A form with the following fields:
email
New pasword (currently a text_input during test but will be real pw)
Confirm password (currently a text_input during test but will be real pw)
Submit button
Currently I am focus on trying to echo the result but I just can't get this to work.
The ultimate target is to send back a confirmation with this API including the new checked password and the token.

I have been trying for quite a long time now so I reach out for help.

Can anyone explain how the execution flow goes on this form handling. Browser can't run the php script. In this example superglobal $_SERVER["PHP_SELF"] used to refer the same html page. when we try to submit the page with empty field it shows the error message in screen. This is happening due to the fact php variable got its error value after submission. I think that after triggering the submit button. This page makes a request to the same page in the server using POST method and in the server we access the same form value using superglobal $_POST["name"],["email"] etc.. and finally the server throws the new html page. Am i right? or this validation is happening entirely in the frontend.
In php the validation is happening entirely in the server ..
The frontend only validate things when JavaScript involved or you add field attributes like required , min , max.
I think w3 is good source to check small code snippets. but it's not good source to learn
I'm super new at coding. This is the form page code

But after I fill up all the information and click submit, the page said cannot connect to SMTP sever host. The strange thing is, I can send email while run the phpmailer index.php alone. The form page php file and the mailer php file is in a different folder but same parent folder, is this the problem?
If one page works and another doesn't, and these are in different folders, then yes, that could be the problem. However, the solution is probably not to just move one of the files (which would probably give you other path related issues), but instead make sure that they both can reach the neccessary configuration (SMTP server host in this case).

I just started learning PHP today so im a beginner and im not very
familiar with it. trying to use php on a local host to make a booking
reservation page for a restaurant. What i was trying to do is make a
form and validate it so that the user wont be able to leave out any
required fields. however it doesnt seem to work. can anyone tell me
where i went wrong please ?
if there aren't any errors you have to check the name of the php file? does it have the extension ".php"?
Are you referring the right directory?
is the server running?
I would like to validate the information before its send it to me. For instance that an email address has an # on it.
I have the following code to introduce: Name, LastName and email. I validated it that they are not empty, but:
How do I send a message to the user to let them know that they need to fill it up? I tried: if ($nameErr == ''){echo "Need to introduce a name"}
but it doens't work
How do I make validation of type: making sure that email address has an # or that a telephone is numeric and has 9 digits?
Thank you so much

you don't actually need to code all validation yourself. It is more convenient if you use a library like http://respect.github.io/Validation/ this.
I'm using this code from W3 (http://www.w3schools.com/php/php_form_complete.asp) to make server side validation for given example form.

Although server side validation works fine,I can't put mail() function to work ONLY WHEN both $name (treated as subject) and $comment (treated as message) fields are filled.
I've tried many combinations but email is always submitted even when fields are empty.
So my question is: how to make this validated form send email only when $name and $comment fields are filled and validated?
As you are creating $nameErr when the name is invalid and $comment is an empty string when the comment is valid you can use the following conditional:
if (!$nameErr && $comment) {
}
Empty strings are considered FALSE:
http://php.net/manual/en/language.types.boolean.php
You can always use flags.
<?php
....
// let's say there are some flags for validation
if($flag1 && $flag2 && .. $flagN){
// perform email sending here
}
?>
Or you can use the default error message variables; check if they are empty
<?php
if(!empty($nameErr) && !empty($comment)){
// perform email sending
}
?>
Do the validation after you validated $name and $comment:
if($nameErr == "" && $emailErr == "") { // If they are empty, no errors where found
// Do your email validation here
}
