Question

Answer 1

A:

You can't do that directly. You have to output the array in some form in your HTML and then have Javascript parse it. I recommend using jQuery in order to parse the HTML into an array.

That's what he's attempting to do; output the imploded array inside a JS array.

Answer 2

+2 A:

You're trying to implode the $giant_says array before you've filled it (you're calling display() after the implode when the call needs to happen before).

Answer 3

+1 A:

The problem is that you call the display method, that fills the content after the html part with the javascript is sended.

the html code is "like" making an "echo 'html'" from your php. Your html is already processed but the display method is not called. call the method before the html code.

Example:

<?php 
    $giant_says = array();
    $giant_says[] = "<a href='http://www.google.com'&gt;Google&lt;/a&gt;";
    $giant_says[] = "Yahoo!";
    $giant_says[] = "Bing"; 

    function display()  {
        global $giant_says;
        echo '<div id="content">'.$giant_says[0]."</div><br><br>";
        $i = 0;
        while($i < count($giant_says))  {
          echo "<input type='button' value='".$i."' onClick=\"addtext(".$i.");\" />";
          $i += 1;
        }  
    }
?>
<html>
    <head>
        <title>Example</title>
        <script type="text/javascript">
          function addtext(index) {
             giantSays = ["<?php echo implode ('","', $giant_says); ?>"];
             document.getElementById('content').innerHTML = giantSays[index];
             return false;
          }
       </script>
    </head>
    <body>
        <?php  display(); ?>
    </body>
 </html>

the reason I have $giant_says[] filled up inside the function is because I have another function that actually fills the array and not the statements that I had here as an example. So I know your solution will work but what I need is the array to be filled inside the function. Is there any way to get that working? Thanks

Answer 4

+2 A:

You have the order wrong, which is causing the implode() to compress an empty array. I also suggest using json_encode() instead of implode(). It exists for this type of thing - example below:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
<html lang="en">
<head>

  <title>Example</title>

  <?php

  $giant_says = array();

  function display(&$giant_says)  {

    // Calculate the array (referenced)

    $giant_says[] = "<a href='http://www.google.com'&gt;Google&lt;/a&gt;";
    $giant_says[] = "Yahoo!";
    $giant_says[] = "Bing";

    // Return the HTML, to display later

    ob_start();

    echo "<div id='content'>";
    echo $giant_says[0];
    echo "</div><br><br>";

    $i = 0;
    while($i < count($giant_says))  {
      echo "<input type='button' value='".$i."' onClick=\"addtext(".$i.");return false;\"";
      $i += 1;
    }
    $Return = ob_get_contents();
    ob_end_clean();
    return $Return;
  }

  $Display = display($giant_says);

  ?>

  <script type="text/javascript">
    function addtext(index) {
        giantSays = <?php echo json_encode($giant_says); ?>;
      document.getElementById('content').innerHTML = giantSays[index];
    }
  </script>

</head>

<body>

  <?php
    echo $Display;
  ?>

</body>
</html>

There is (almost) always a way, I've edited my solution to show my take on how to achieve that.

Mahdi.Montgomery 2010-10-01 18:59:54

I can't express how grateful I am to your reply. Thanks for your advice. That's the perfect solution I was looking for.

2010-10-02 23:57:57

No problem, accept as the solution if it helped you out. Thanks.
