How can I prepare mysqli statement that uses arrays? - php

Question

Im using the below form
<form method="get" action="daily_process.php">
Horse / Course / Time
<input type='text' name='horse[]' />
<input type="text" name="course[]" />
<input type="text" name="time[]" />
<input type='text' name='horse[]' />
<input type="text" name="course[]" />
<input type="text" name="time[]" />
<input type='text' name='horse[]' />
<input type="text" name="course[]" />
<input type="text" name="time[]" />
<input name="submit" type="submit" />
</form>
Im using the below code to process the form array and output it as print
<?php
$horse = $_POST['horse'];
$course = $_POST['course'];
$time = $_POST['time'];
foreach( $horse as $key => $h ) {
if ($horse[$key] != "") {
print "The horse is ".$h.", course is ".$course[$key].
", and time is ".$time[$key]." Thank you <br/>" ;
}}
?>
my question is how can I prepare these results for mysqli?
I have seen the below example on StackOverflow, but how can I edit it to suit my purpose?
ie. I need to save $horse, $course, and $timeto database -
table (horse,course, time) VALUES (?, ?, ?)
$query = "INSERT INTO table (link) VALUES (?)";
$stmt = $mysqli->prepare($query);
foreach ($array as $one) {
$stmt ->bind_param("s", $one);
$stmt->execute();
}
$stmt->close();

Answer 1

$query = "INSERT INTO table (horse,course,time) VALUES (?,?,?)";
$stmt = $mysqli->prepare($query);
foreach( $horse as $key => $h ) {
$stmt ->bind_param("sss", $h, $course[$key], $time[$key]);
$stmt->execute();
}
Assuming all the values are strings
The examples for bind_param in the PHP docs do show how to bind multiple values.
