Get selected option from html via php - php

Question

I have a simple simple question, And is so strange for me.
In my HTML file I have a button and a form tag in which used select tag with some options as :
<form action="" method="post" name="general"> Wireless mode
<select name="wirelessmode" id="wirelessmode">
<option value="ap">AP</option>
<option value="client">Client</option>
<option value="clientbrdige">Client Bridge(Routed)</option>
<option value="adhoc">Adhoc</option>
<option value="wdsstation">WDS Station</option>
<option value="wdsap">WDS AP</option>
</select> <br>
</form>
<form action="" method="post" name="apply">
<input type="submit" name="apply" value="Apply"/>
</form>
Include that HTML file in my Php file, create a class and a function to display the selected option of the HTML as below :
<?php
include('./view/config.html');
class SSHCommand{
public function display(){
if (isset($_POST['apply'])) // press button {
$category = $_POST['wirelessmode']; // get the select option
echo $category;
}
}
}
$sshCommand=new SSHCommand();
$sshCommand->display();
?>
When i try, it gives me nothing !
But when i try :
echo 'david';
instead of
echo $category;
It prints david after press apply button.
Where I am doing wrong?

Answer 1

you can get a result using single FORM, modified your HTML code as per bellow.
<form action="" method="post" name="general" id="general_form"> Wireless mode
<select name="wirelessmode" id="wirelessmode">
<option value="ap">AP</option>
<option value="client">Client</option>
<option value="clientbrdige">Client Bridge(Routed)</option>
<option value="adhoc">Adhoc</option>
<option value="wdsstation">WDS Station</option>
<option value="wdsap">WDS AP</option>
</select>
<input type="submit" name="apply" value="Apply"/>
</form>

You would have to include your config.html as html with a php extension .. config.php for the html include to work.. that would be a key thing.
You can include HTML or text in a PHP include file. Anything that can go in an standard HTML file can go in a PHP include.
Your entire website should be subsequently saved using .php extensions however, whether they include php or not, that's the downside, eg. index.php rather than index.html, so it could be time-consuming. Some servers don't require this, so test your configuration first.
Best of luck

Your select is in one form block and the submit button is in another. The default nature of the submit button will submit only the html elements in that form and not all forms of the page. So to get this to work, you need to keep one form with the required elements as
<form action="" method="post" name="general"> Wireless mode
<select name="wirelessmode" id="wirelessmode">
<option value="ap">AP</option>
<option value="client">Client</option>
<option value="clientbrdige">Client Bridge(Routed)</option>
<option value="adhoc">Adhoc</option>
<option value="wdsstation">WDS Station</option>
<option value="wdsap">WDS AP</option>
</select> <br>
<input type="submit" name="apply" value="Apply"/>
</form>
