PHP Form submit with arrays as rows

Question

I have the following form in php, but I want to make the insert.php action, to insert everything in a new row in MySQL... I don't know how to do it, because there are several fieldsets, it's easy with one simple form, but not for each $_cliente and $_servicio

CODE UPDATE

<?php
require("database.class.php");
//database server
define('DB_SERVER', "localhost");

//database usuario
define('DB_USER', "root");
//database password
define('DB_PASS', "root");
define('DB_DATABASE', "nivelservicio");
$db = new Database(DB_SERVER, DB_USER, DB_PASS, DB_DATABASE);
$db->connect();
    $sql    = "SELECT * FROM servicios";
    $_row = $db->query($sql);
    $_servicios = array();
    while($row = $db->fetch_array($_row)) {
        $_servicios[$row['id']] = $row['nombre'];
    }

    $sql    = "SELECT * FROM clientes";
    $_row = $db->query($sql);
    $_clientes = array();
    while($row = $db->fetch_array($_row)) {
        $_clientes[$row['id']] = $row['nombre'];
    }
?>

You need to change the name of your input fields to arrays like this:

<select name="estado[]">

And then in your PHP you can do this:

<?php

foreach ($_POST['estatdo'] as $key => $val) {
    echo $_POST['estatdo'][$key] . ' - ' echo $_POST['texto'][$key] . ' - ' echo $_POST['servicio_id'][$key] . '<br />'; 
}

Here's a full example:

<form action="insert.php" method="post">
<div id="formfieldset">
    <?php foreach ($_clientes as $key_cliente => $cliente) :
        switch ($cliente) {
            case "Produban":
                $_servicios = array_diff($_servicios, array(
                    "GESTI",
                    "VULCANO"
                ));
                break;
        } ?>

        <h1><?php echo $cliente ?></h1>
        <input type='hidden' name='cliente_id[<?php echo $key_cliente ?>]' value='<?php echo $key_cliente ?>'>
        <?php foreach($_servicios as $key_servicio => $servicio) : ?>
            <h2><?php echo $servicio ?></h2>
            <input type="hidden" name="servicio_id[<?php echo $key_cliente ?>][<?php echo $key_servicio ?>]" value="<?php echo $key_servicio; ?>">
            <label>Estado</label>
            <select name="estado[<?php echo $key_cliente ?>][<?php echo $key_servicio ?>]">
                <option value="OK">OK</option>
                <option value="KO">KO</option>
            </select>
            <label>Texto</label><input type="text" name="texto">
        <?php endforeach; ?>
    <?php endforeach; ?>

    <br>
    <input type="submit" name="insertar" value="Insertar">
</div>
</form>

So in this example we have a double nested array so instead of estado[] we have estado[][]. Also instead of using [] which makes an array with consecutive numeric keys (i.e., 0, 1, 2, 3) I've changed it to use the client id and the service id like this:

<select name="estado[<?php echo $key_cliente ?>][<?php echo $key_servicio ?>]>

And then in your php you can loop through it like this:

foreach ($clientes as $key_cliente => $cliente) {
    foreach ($servicios as $key_servicio => $servicio) {
        echo $_POST['estado'][$key_cliente][$key_servicio] . '<br />;
    }
}

This works fine, but there's a problem with $keys. I have 7 $_cliente and about 40 $_servicio... so it mess up with $key for cliente when > 7... ( ! ) Notice: Undefined offset: 8 in /var/www/nivelservicio/insert.php on line 14

Can you give me some advice please? Thank you :)

So i've updated the answer to show you how to do a nested array

chrislondon Over a year ago

@user1381537 My guess is that $_POST['insertar'] is not set. Try having var_dump($_POST) the very first line right after the opening <?php

chrislondon Over a year ago

Instead of having the submit button with the name have a hidden field with it instead <input type="hidden" name="insertar" value="true" /> The reason is you can submit forms without clicking the submit button. If you submit a form (i.e., by pressing enter from inside an input field) the submit button's value is NOT sent!
