HTML Question

PHP didn't see hard setup value for input when it is disabled

But... One problem is still appear. When I set up value for hard in HTML:

enter image description here

<div class="flex">
<div class="field">
<input name="subject_field" id="subject_field" placeholder="Temat" value="Testing" disabled>
<label class="icon" for="subject_field">
<i class="fa fa-star fa-fw" aria-hidden="true"></i>
</label>
</div>
</div>


My PHP code didn't see that in this field is something inside.

I want to have input for subject/topic and selection for subject/topic. I will be comment one of them if I don't need them. But also I want to have third variant - input for subject/topic with hard setup setup value. But this not working as I except.

Now that is the main problem. Why? And how to resolve this one. It is very important for me. Please advice.




UNDER IS THE MAIN QUESTION - one problem was solved by me.




Ok, I have to edit my question because I see that nobody can not understand me.

Well, so again:
I have very low knowledge about PHP, but even so I created simply contact form only in PHP. It works very well but I would like to upgrade it and I don't know how.

That contact form looks that:

enter image description here

It is in Polish because I from Poland. I am asking here because we do not have in Poland place like this for asking help.

Now, what I would like to change? You can see field named "Temat" (well it is not name, but placeholder)? It means Topic. Now everybody can topic message as they want. I want to change it and set up "hard" topics. Then everybody will only can choice my topics. So what is the problem?

Even if I now setup hard "topic" via "value=something" (in HTML) then PHP thinks that this field is empty and of course return error. I have to setup variable in PHP code.

I suppose if I now create new field for list choice then PHP still will be think that field is empty. And I don't want to create variables for each topic. I would like to setup PHP for reading what is in field and setup variable by self.

Now here I don't know what to do and how. Because I am newbie. Don't tell me go back to book and learn whole PHP. Please advice.

Here is code of PHP: https://github.com/IdolwSzutrab7/Contact-Form/blob/master/submit.php It is little long and I don't know to paste it here or not?

Well... When I setup value for "hard" like this:

enter image description here

Then I have to setup variable for "hard" in PHP, like this:

enter image description here

Otherwise PHP return error while send form.

I am sure at 90% that same situation will be when I add selection field in the form - I mean PHP will not recognize choice from selection. That is the problem.

Hmm... I think I found what is wrong. My PHP code only check if the value of specified fields are set. Not if they contains something. Even if value is empty for PHP it means it is set. Please look at this section:

if ( !isset($_POST['name_field']) ||
!isset($_POST['address_field']) ||
!isset($_POST['message_field']) )


So now the main question is how to rebuild it for checking if these values contains something not checking if they are set.

Answer

This code:

  <input name="subject_field" id="subject_field" placeholder="Temat" value="Testing" disabled>

should be:

  <input name="subject_field" id="subject_field" placeholder="Temat" value="Testing" readonly>

The disabled function in your code won't post the input value of "subject_field" to the PHP file.
