How to insert multiple values into database using php for loop - php

Question

i have one textbox and one dropdown box in each row.
now i want to enter some date in text box and select some value in dropdown.
when i click it should get saved into database.
How can i do this?
here is my code
php insert code:
When i click submit this php code should
<?php
mysql_connect("localhost", "tiger", "tiger") or die(mysql_error());
mysql_select_db("theaterdb") or die(mysql_error());
$query = mysql_query("INSERT INTO movie (movie_name,language) VALUES('$_POST[Fname]','$_POST[language]') ") or die(mysql_error());
?>
drop down is generated dynamically
code:
function create(param) {
'use strict';
var i, target = document.getElementById('screens');
target.innerHTML = '';
for(i = 0; i < param; i += 1) {
target.innerHTML +='</br>';
target.innerHTML +='New Movie '+i+' ';
target.innerHTML += '<input type="text" name="Fname">';
target.innerHTML +=' '+'Language '+' ';
target.innerHTML += "<?php
try {
$dbh = new PDO('mysql:dbname=theaterdb;host=localhost','tiger','tiger');
} catch (PDOException $e) {
echo 'Connection failed: ' . $e->getMessage();
}
$sql = 'SELECT language FROM languages;';
$sth = $dbh->prepare($sql);
$sth->execute();
echo "<select name='language' id='course'>";
echo "<option>----Select Language----</option>";
while($row = $sth->fetch(PDO::FETCH_ASSOC)) {
echo "<option value='" . $row['language'] ."'>" . $row['language']. "</option>";
}
echo "</select>";
?>";
target.innerHTML +='</br>';
target.innerHTML +='</br>';
}
}
the ui looks something like this...

Answer 1

Add name
for text box and select box like this
name="text_box"+i and name="select_box"+i. "i"
is value from counter in loop, for example if you have 100 New Moview you will have name for each text box like this text_box1, text_box2. ..... text_box100. You should on submit remeber the numbers of "New MovieS" and that is "i" and in php code just loop for each element and save them. In first iteration you will have $_POST[Fname1] and $_POST[language1], etc..

Answer 2

Add a line in your js which makes the inputs to print something along the lines of target.innerHTML = '<input name="RowCount" value="' + param + '" hidden />' then in your PHP use:
for ($i=0; $i < $_POST["RowCount"]; $i++) {
$query = sprintf("INSERT INTO movie ('movie_name', 'language') VALUES ('%s', '%s')",
mysqli_real_escape_string($_POST["Fname"]), // Escaping values before inserting.
mysqli_real_escape_string($_POST["language"]));
mysqli_query($con, $query);
}

Answer 3

in HTML Form: Set textbox and dropdown element name as same algorithm ElementName+RowNumber;
insert element for RowCount: <input type="hidden" name="RowCount" value="3">
in PHP: get values:
for($iRow=0;$iRow less $_POST['RowCount'];$iRow++) {
mysql_query("INSERT INTO movie (movie_name,language) VALUES('".$_POST['Fname'.$iRow]."','".$_POST['language'.$iRow]."');
}
