从php发送数组到javascript文件

Question

I want to send an array that is being created on a php file to a javascript file. The codes that I have made are the below but I cannot make it work.

sample.php

<form action="new-game.php" method="post">
<?php $playerNames = array();
    for ($i=0; $i<$_POST["playerNo"]; $i++) {
        echo "<form name=\"input\" action=\"#\" method=\"POST\">Όνομα: <input type=\"text\" name=\"playerName\" value=\"\"><br/>";
        $playerNames[$i] = $_REQUEST['playerName'];
    }
?>

    </br></br>
    <input type="submit" value="Αποστολή" onclick='showNames(<?php echo json_encode($playerNames); ?>);' />
</form>

And I don't know how I should use the $playerNames array on script.js file.

Answer 1

Have you included your javascript file ? And is the function showNames() present ?

<script type="text/javascript" src="yourfile.js"></script>

Look at my example to send datas from PHP to Javascript. The trick is to close the PHP tag, and to open a Javascript one.

<?php
    $my_array; //replace by your own array
    for($i = 0; $i < count($my_array) -1; $i++) {
    ?>
        <script>
            myFunction(<?php echo $my_array[$i]; ?> );
        </script>
    <?php   
} 
?>

EDIT :

It seems to me that this line is wrong.

<input type="submit" value="Αποστολή" onclick='showNames(<?php echo json_encode($playerNames); ?>);' />

Try using this following one instead :

<input type="submit" value="Αποστολή" onclick='showNames(<?php echo json_encode($playerNames); ?>)' />
