Javascript that executes php class

[porsche21]

What code do I need in my view()function that triggers the oopClasses.php page that executes the classes and function MapIt()?

function view(){
	createXMLHttpRequest();
	loadingMessage();
	var url = "oopClasses.php?";
	xmlHttp.onreadystatechange = handleStateChange;
	xmlHttp.open("GET", url + new Date().getTime(), true);
	xmlHttp.send(null);
}

<?php class Maps
{
    function viewmaps()
    {
        GLOBAL $sybconnect;
        $sql="select distinct cellname,centname from celltech order by cellname";
        $link=$sybconnect->query($sql);
        $i=0;
        while($row=$sybconnect->fetchArray($link)){
            $output[$i]['cellname']=$row['cellname'];
            $output[$i]['centname']=$row['centname'];
            $i++;
    }
    //$connect->close();
    return $output;
}

    function MapIt(){
        if(isset($this)){
        //user wants to see the maps
        $maps = new Maps();
        $displaysite = $maps->viewmaps();
        
        ?>
        <div style="height:400px;overflow:auto">
        <table>
            <tr>
                <th>Cell Name</th>
                <th>&nbsp;</th>
                <th>Centname</th>
            </tr>
        <?php
        for($i=0;$i<count($displaysite);$i++){
            ?>
            <tr>
                <td><strong><?php echo $displaysite[$i]['cellname'];?> (<a href="http://<?php echo $_SERVER['SERVER_NAME'].$_SERVER['PHP_SELF'];?>?option=cellname&task=editmap&cellname=<?php echo $displaysite[$i]['cellname'];?>">Edit</a>)</strong></td>
                <td>maps to</td>
                <td><strong><?php echo $displaysite[$i]['centname'];?></strong></td>
            </tr>
            <?php
        }
        ?>
        </table>
        </div><?php
          }
    }    ?>

you can't directly, however you are calling the php file javascript, so just add the function at the end of your php file :

<?php class Maps
{
    function viewmaps()
    {
        GLOBAL $sybconnect;
        $sql="select distinct cellname,centname from celltech order by cellname";
        $link=$sybconnect->query($sql);
        $i=0;
        while($row=$sybconnect->fetchArray($link)){
            $output[$i]['cellname']=$row['cellname'];
            $output[$i]['centname']=$row['centname'];
            $i++;
    }
    //$connect->close();
    return $output;
}

    function MapIt(){
        if(isset($this)){
        //user wants to see the maps
        $maps = new Maps();
        $displaysite = $maps->viewmaps();
        
        ?>
        <div style="height:400px;overflow:auto">
        <table>
            <tr>
                <th>Cell Name</th>
                <th>&nbsp;</th>
                <th>Centname</th>
            </tr>
        <?php
        for($i=0;$i<count($displaysite);$i++){
            ?>
            <tr>
                <td><strong><?php echo $displaysite[$i]['cellname'];?> (<a href="http://<?php echo $_SERVER['SERVER_NAME'].$_SERVER['PHP_SELF'];?>?option=cellname&task=editmap&cellname=<?php echo $displaysite[$i]['cellname'];?>">Edit</a>)</strong></td>
                <td>maps to</td>
                <td><strong><?php echo $displaysite[$i]['centname'];?></strong></td>
            </tr>
            <?php
        }
        ?>
        </table>
        </div><?php
          }
    }    
   
   MapIt();
 
?>

Okay I made some changes to my javascript and also added some code to the beginning of my php. Can you tell me why I am getting this error (Call to a member function on a non-object)?

function view(){
	createXMLHttpRequest();
	loadingMessage();
	var date = new Date();
	var timestamp = date.getTime();
	var poop = true;
	var queryString = "poop=" + poop;
	xmlHttp.onreadystatechange = handleStateChange; 
	xmlHttp.open("GET","oopClasses.php?"+ queryString + "&time=" + timestamp,true);
			xmlHttp.send(null); 
}

<?php
if(isset($_GET['poop']) && $_GET['poop'] == 'true'){
    
    $test = new Maps();
    MapIt();
}
class Maps
{
    function viewmaps()
    {
        GLOBAL $sybconnect;
        $sql="select distinct cellname,centname from celltech order by cellname";
        $link=$sybconnect->query($sql);
        $i=0;
        while($row=$sybconnect->fetchArray($link)){
            $output[$i]['cellname']=$row['cellname'];
            $output[$i]['centname']=$row['centname'];
            $i++;
    }
    //$connect->close();
    return $output;
}

    function MapIt(){
        if(isset($this)){
        //user wants to see the maps
        $maps = new Maps();
        $displaysite = $maps->viewmaps();
        
        ?>
        <div style="height:400px;overflow:auto">
        <table>
            <tr>
                <th>Cell Name</th>
                <th>&nbsp;</th>
                <th>Centname</th>
            </tr>
        <?php
        for($i=0;$i<count($displaysite);$i++){
            ?>
            <tr>
                <td><strong><?php echo $displaysite[$i]['cellname'];?> (<a href="http://<?php echo $_SERVER['SERVER_NAME'].$_SERVER['PHP_SELF'];?>?option=cellname&task=editmap&cellname=<?php echo $displaysite[$i]['cellname'];?>">Edit</a>)</strong></td>
                <td>maps to</td>
                <td><strong><?php echo $displaysite[$i]['centname'];?></strong></td>
            </tr>
            <?php
        }
        ?>
        </table>
        </div><?php
          }
          
    }    
    ?>

you need to define the function/class first before calling it.

Ex:

function dog(){
   echo 'bone!';
}

$new = dog(); 

and not

$new = dog(); 

function dog(){
   echo 'bone!';
}
