    Calling Javascript function in php script.

    Not sure if I should post this to a javascript group or here. So I'll
    try here first since most here mix both in this group. I am trying to
    pass a php value into a JavaScript function that changes the state of a
    particular radio button. The call is:

    setCheckedValue ("abbr_lette r", $_SESSION['abbr_letter'])

    Here is a snip of the code I am trying to get to work. Everything else
    works except for the radio button being set. I just not sure if I have
    things correct.

    Any help would be appreciated.


    session_start() ;
    if(!isset($_SES SION['abbr_letter']))
    $_SESSION['abbr_letter'] = 'A';

    require_once 'includes/config.inc.php' ;
    require_once 'includes/header.inc.php' ;
    //
    // Start a Form
    $cssfile = 'quotes.css';
    ?>
    <html>
    <head>
    <link href="<?php echo $cssfile; ?>" rel="stylesheet "
    type="text/css">
    <SCRIPT LANGUAGE=”JavaS cript”>
    setCheckedValue ("abbr_lette r", $_SESSION['abbr_letter'])

    function setCheckedValue (radioObj, newValue) {
    <?php print("radioObj , newValue: " . radioObj . " . " .
    newValue) ?>
    if(!radioObj)
    return;
    var radioLength = radioObj.length ;
    if(radioLength == undefined) {
    radioObj.checke d = (radioObj.value == newValue.toStri ng());
    return;
    }
    for(var i = 0; i < radioLength; i++) {
    radioObj[i].checked = false;
    if(radioObj[i].value == newValue.toStri ng()) {
    radioObj[i].checked = true;
    }
    }
    }
    </SCRIPT>
    </head>

              Yea, I rewrote the js function and I know it works now... I just need to
              find the right place to call it in my code.

              function setCheckedValue (newValue) {
              var len = document.author _abbrv.abbr_let ter.length
              for(var i = 0; i < len; i++) {
              document.author _abbrv.abbr_let ter[i].checked = false;
              if(document.aut hor_abbrv.abbr_ letter[i].value ==
              newValue.toStri ng()) {
              document.author _abbrv.abbr_let ter[i].checked = true;
              }
              }
              }

                  You can't "call" a JS function from your code. PHP runs on the server,
                  and JS on the client.

                  You can, however, echo a value from PHP in the JS code.
