// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

I create a select option for all checkbox generated from database.How can i get value from select option and insert in database?

Admin
Hi,
Try put a fixed name to that <select>, with "[]" to can have multiple values from the same name into an array.

Code: Select all

<select name="intrb[]">

Then, where you want to get the selected options and to perform Insert, use like this:

Code: Select all

if(isset($_POST['intrb']) && count($_POST['intrb'])>0){
  $sql="INSERT INTO table_name (col_name) VALUES ('". implode("'),('", $_POST['intrb']) ."')";
  //Here execute the $sql with the php extension query you use, PDO or MySQLi.
}

Try this in your code from first post:

Code: Select all

if(isset($_POST['tv']) && count($_POST['tv'])>0){
  $nri = count($_POST['tv']);
  for($i=0; $i<$nri;$i++){
    $question = $_POST['tv'][$i];
    $answer = isset($_POST[$question]) ? $_POST[$question] :'';
    $sql="INSERT INTO table_name (answer, question) VALUES ('". $answer ."', '". $question ."')";
    //Here execute the $sql with the php extension query you use, PDO or MySQLi.
  }
}

What name is necessary to put at the select option ?

Admin
At the <select> element let the name as you set it in your code ($link['intrebare']).
Then, according to your code that creates the checkbox and <select> elements; this code reprsents the checkbox value which is also the name of the select associated to that checkbox.

Code: Select all

$question = $_POST['tv'][$i];

And this code gets the selected option.

Code: Select all

$answer = isset($_POST[$question]) ? $_POST[$question] :'';


- Or, better set the name of select like this:

Code: Select all

<select name="intrb[]">

And change define $answer with this code:

Code: Select all

$answer = isset($_POST['intrb'][$i]) ? $_POST['intrb'][$i] :'';
