Hello World,  
i’m trying to do the steps of the code corner (day 2). I copied the syntax shown there and made some adjustments to my own needs.

So the code for my class.uiajaxchat.inc.php is now:

_\<?php  
class uiajaxchat  
{  
var $public\_functions = array(  
‘ajaxchatinterface’ =\> True,  
);_

```
public function create_header ()
{
	$GLOBALS['egw']->common->egw_header();
	echo parse_navbar();

}

public function create_footer ()
{
	$GLOBALS['egw']->common->egw_footer();
}

function ajaxinterface ()
{
    $this->create_header();
    if (trim($_POST['fname'].$_POST['sname'])!='')
    {
        //echo ''.$_SERVER['PHP_SELF'].'<br>';
        echo "<br>Hello ".$_POST['fname']." ".$_POST['sname']."<br>";
        echo "<form action='".$GLOBALS['egw']->link('/index.php',array(
    'menuaction' => 'AjaxChat.uiajaxchat.ajaxchatinterface','message'=>'YES'))."' method='post'>
        <input type='submit' value=' Reload '>
        </form>";
    }
    else
    {
        echo "Type a name to be greeted accordingly <br>";
        echo "<form action='".$GLOBALS['egw']->link('/index.php',array(
    'menuaction' => 'AjaxChat.uiajaxchat.ajaxchatinterface','message'=>'NO'))."' method='post'>
          <p>first name:<br><input name='fname' type='text' size='30' maxlength='30'></p>
          <p>name:<br><input name='sname' type='text' size='30' maxlength='40'></p>
                <input type='submit' value=' Submit '>
                <input type='reset' value=' Cancel'>
        </form>";

    }
    $this->create_footer();
}

```

}

When i try to run the script i allways get the error:

_Parse error: syntax error, unexpected T\_STRING, expecting T\_OLD\_FUNCTION or T\_FUNCTION or T\_VAR or ‘}’ in /path\_to\_egw/AjaxChat/inc/class.uiajaxchat.inc.php on line 8_

So the problem is with the “public function” declaration…  
This error occured allready in the first steps of day two, so i just copy&paste this code and made my adjustments, hoping to get around them… but as you can see it didnt work.

I hope someone is able to help me. Thanks alot allready!  
Greetings - Eric

If I take the content of your post, put that into a file and call it from  
somewhere  
$this-\>ajaxchat =& CreateObject(‘YOURAPP.uiajaxchat’);  
$this-\>ajaxchat-\>ajaxinterface();  
It works as expected for me …

Hey Klaus, thanks for the fast answer.  
I’m not sure if I did everything right, but i followed the steps of the code corner, so i have the /AjaxChat/index.php with the one line of code reffering to my class. I also have the class.uiajaxchat.inc.php as mentioned before.

Where do i have to put the lines you wrote?

Eric

If you have the index.php, with that one line of code, it does about the  
same  
as I did with the two lines to call that bit of code from somewhere else.  
The line with the CreateObject, does the class instanciation, and the  
line $this-\>ajaxchat-\>ajaxinterface(); just calls the function.

header(‘Location:  
…/index.php?menuaction=YOURAPP.uiajaxchat.ajaxinterface’);  
Does about the same, but somewhere else.

Just a guess, you use the php5 qualifier “public” on a php4 server

Oh damn, you’re right. But what can I do now? Is it possible to declare just a “function” and use it the same way as a “public function”. Can I still follow the steps of the Code Corner?

Thank you very much allready. You helped quite alot.

Ok, obviously it is possible to do so. 🙂  
I tried and it seems to work.
