How can I insert appended input field data to mySQL database? - php

Question

I append some input fields to my container and want to add for each an entry in my mysql database. This is working well so far:
<?php
if (isset($_POST['submit_val'])) {
if ($_POST['name']) {
foreach ( $_POST['name'] as $key=>$value ) {
$pdo = $db->prepare('INSERT INTO friends (name) values(:name) ');
$pdo->execute(array(
':name' => $value,
));
}
}
echo "<i><h2><strong>" . count($_POST['name']) . "</strong> items added</h2></i>";
}
?>
<?php if (!isset($_POST['submit_val'])) { ?>
<form method="post" action="">
<div id="container">
<p id="add_field"><span>Click To Add</span></p>
</div>
<input type="submit" name="submit_val" value="Submit" />
</form>
<?php } ?>
<script type="text/javascript">
var counter = 0;
$(function() {
$('p#add_field').click(function() {
counter += 1;
$('#container').append(
'<strong>No. ' + counter + '</strong><br />' + '<input id="field_' + counter + '" name="name[]' + '" type="text" /><br/>');
});
});
</script>
But I wish to have as fields not only name, also age and gender:
$('#container').append('<strong>No. ' + counter + '</strong><br />' + '<input id="field_' + counter + '" name="name[]' + '" type="text" /><input id="field_' + counter + '" name="age[]' + '" type="text" /><input id="field_' + counter + '" name="gender[]' + '" type="text" /><br/>');
and add them into the database:
$pdo = $db->prepare('INSERT INTO friends (name,age,gender) values(:name,:age,:gender) ');
$pdo->execute(array(
':name' => $value,
':age' => $value,
':gender' => $value,
));
But now I have a logical problem of understanding. How can I get the other values into my foreach loop foreach ( $_POST['name'] as $key=>$value ) { because I need one loop for all values together?
I could imagine something like this:
foreach ( $_POST['name'] as $key=>$name && $_POST['age'] as $key=>$age && $_POST['gender'] as $key=>$gender ) {

Assuming occurrences of all the three fields are same you can use:
foreach($_POST['name'] as $key=>$val){
echo $val." ".$_POST['age'][$key]." ".$_POST['gender'][$key]."<br>";// you can use these value in your insert
}
