Just add tag in the following line of code
The form tag is used to create a form for user input.
You need to have your input s within form tags. Also, you need to define the forms method (if not given, it will be set to GET ).
So, your code should look like this:
Mysql — Pass value of html to PHP variable, 2 You can’t pass data directly html to php.

put your HTML in a form as follow
that will solve your issue if you want to make fancy js effect then use JQUERY to submit you form
You have to enclose the whole form into these tags:
Furthermore, your submit button should look like this:
Then you can access the passed values via:
You don’t need the function stuff. Also, begin to look into SQL Injection and how to protect against it. Your code, in the wild, would be vulnerable. In your SQL, you need to also wrap your string values with single quotes.
connect_error) < die("Connection failed: " . $conn->connect_error); > // sql to create table $sql = "INSERT INTO users (username, password, name, company, supervisor, phone, admin, exempt) VALUES('$username', '$password', '$name', '$company', '$supervisor', '$phone', '$admin', '$exempt')"; if ($conn->query($sql) === TRUE) < echo "New record created successfully"; >else < echo "Error: " . $sql . "
" . $conn->error; > $conn->close(); > ?> Html — Simple PHP: getting variable from a form input, PHP is a server-side language, so you’ll need to submit the form in order to access its variables. Since you didn’t specify a method, GET is assumed, so you’ll need the $_GET super-global: echo $_GET [‘name’]; It’s probably better though, to use $_POST (since it’ll avoid the values being passed in the URL directly.
Passing variable from html input to included php file
I have situation where I have an accordian and I am referencing a php file gridlist.php within another php file displayvar.php. In other words the context of displayvar.php are shown in the webpage gridlist.php. Now gridlist.php has a checkbox input:
I like ice cream I like pizza I like soda Now when I check on the checkboxes in the table referenced by gridlist.php displayvar.php should be able to display a list of the items checked. For instance it should display if all three checkboxes are checked:
If the last one is checked then only soda should be displayed. Keep in mind because this displayvar.php is displayed within the context of the website gridlist.php I used the following command in gridlist.php:
I tried in the displayvar.php to obtained the variables foodlike (as defined by the variable id in the checkbox gridlist.php) from gridlist.php and then echo them based on this snippet of code:
How can I tweak this code to get my desired result?
You can achieve this with :
I like ice cream I like pizza I like soda As you mentioned you did not want a submit button, you’ll probably want some sort of «interactive», instant solution and bypass going to the server, i.e. bypass PHP. Since the include ‘foo.php’ -statement effectively dumps all contents of foo.php into the current file (you could say it «merges them into one»), all interactions happen on the same page . Thinking about your setup as «file A is communicating with file B via the server» is wrong — there is only one file/page.
So, having said all this, my proposed solution uses Javascript and the seemingly omni-present jQuery library, which you will have to include in your page. The snippet below binds an event-handler to the input s’ change -event, which is triggered when a checkbox or radio are checked or the value of a text-input is changed. Then, we append the checked value to a **** container for display.
Edit : This is how I would lay out the «root» file containing the two gridlist.php and displayvar.php, along with the Javascript required to manipulate the DOM:
label Edit 2 : You still seem to be having problems, so I shall try to clarify why I think you are not succeeding.
Using only PHP, it is not possible to access the value of a checked checkbox without submitting the form back to the server.
To retrieve the value of a checkbox that has been checked by the user, you essentially have only two possibilities .
Option 1: Submit the form using POST/GET This entails you having a element enclosing the inputs along with a submit button for submitting the form. This is how (probably) 98% of forms on the Internet work. The data in the form is sent, using either the POST or GET method, to the script you specify in the form-tag. Consider this as an example (text omitted):
When the user clicks the submit-button, the form is sent to handler.php via the GET method. There, the form data will be available in the $_GET array. Same applies for POST. Now, an often-used approach is to submit the form to the same script via action=»#» , meaning you need not have a dedicated handler, but can process data within the same script as your form. Obviously, you will have to distinguish two cases: one initial case where no data is set in $_GET/$_POST, and one submission-case when the data is set.
The same applies to data stored in the $_SESSION, btw: again, you will have to tell a server-side script to put the data you want in the user-session; only then will you be able to retrieve it again.
A similar approach I would call «Option 1 b)» is submission via AJAX. This is basically form submission without leaving/reloading the page. Sending the data is done via Javascript and an «XMLHttpRequest». An XHR lets you send any type of data, not only XML. Again, similar logic applies: you serialize the data in some way, provide an endpoint, usually a script, to talk to, and communicate the data to that script via POST/GET. Then your script can handle the data and return a response, which will be available in the JS that initiated the AJAX-request.
Option 2: By accessing the DOM directly The DOM is the «tree» that is made up of the HTML-elements of your page. Using Javascript, one can access and modify these elements, remove specific ones or add new ones. This API used to be implemented quite differently across browsers, which is why libraries like jQuery or Prototype were created: they provide a unified API across different user agents. We can use two features of these libraries:
This is the approach I used in my answer, which I will not repeat here and you can read above. We respond to the event of the user clicking on a checkbox, and access that very checkbox to retrieve the value-data and process it further.
TL;DR
You have two options: submit the form to a script and process the data there; or, manipulate the DOM to catch user-events and pull out the values.
