can't call JavaScript function from php

[evicailieva]

A have a php scrip where I call a JavaScript function. I don't know why, but it doesn't work. At the beginning, when I was writing the script it was working but now it's not. I don't know wхat to do. Please help me. Here is the php code:

    function print_rezBilet($rezBilet,$posRezBilet1){
        $step=$_SESSION['cekor'];
        $max=$_SESSION['max'];
        $curr= $_SESSION['currentRezBilet']+$step-1 ;
 
 
        if($max<$curr)
            $curr=$max;
 
        //vo ovie dve promenlivi se zacuvuva brojot na prikazanata strana i
        //vkupniot broj na strani
        $currPage=ceil($curr / $_SESSION['cekor']);
        $maxPage=ceil($max / $_SESSION['cekor']);
        if (!$rezBilet) {
            echo error_message('Íå ñå âíåñåíè ðåçåðâàöèè íà áèëåòè');
            echo <<<END
            <tr><form method="post" action="$posRezBilet1" ><td align="center">

I call the functions on other places too, but it doesn't work there neither :

        <input type="button" value="èçëèñòà¼" onClick="showListTurInsert()" class="button">
    </td>
</tr>
 

PLEASE HELP ME

[Atli]

Please post your code inside [code] tags! It's impossible to read it without them.

What have you changed since the code worked?
Are you getting any PHP or JavaScript errors?
What is your code supposed to be doing? How is it not working?

[jx2]

 
<a  href="?showTur='.htmlentities($rezB['TURIST_ID']).' 

i'm not sure but i think it won't work
shouldnt that be urlencode() as it is part of a url?

here is the code in code tags

</form>
</table></center>
END;
}
} [/PHP]

this is only the part where I call the functions, and here are the JavaScript functions

function showListTurist() 
    {
        <?php
            $_SESSION['showTur']=$_GET['showTur'];
        ?>
        sList = window.open("turist_prozorecB.php", "turist", "width=800,height=200, scrollbars=yes");
    }
 
    function showListBilet() 
    {
        <?php
            $_SESSION['showBil']=$_GET['showBil'];
            echo "neso";
        ?>
        sList = window.open("bilet_prozorecB.php", "bilet", "width=800,height=100, scrollbars=1");
    }

The code prints the values stored the array $rezBilet in a table and I want when you press on the picture 'details' to open new window. That's why I call the JavaScript function. But I also want to send the variable $rezB['TURIST_ID'] to the new window that opens, so thats why I use href=?showTur..., and then in the JavaScript function I put it in session.
I don't get any kind of errors, it does nothing, and the biggest problem is, that I that I haven't changed much. I only added some things but on the other part of the script that has not much connection whit this (I think). It just stop working.
Just adds the value from $rezB['TURIST_ID'] to showTur, but it doesn't call the JavaScript functions.
Sorry that I didn't write correctly the previous post, but I'm new at this.

[jx2]

you should use [ php] [ /php] tags for your code

what do you mean do not call javascript? php cant call javascript anyway...

regards jx2

[pbmods]

Heya, evicailieva. Welcome to TSDN!

You're having trouble because (as JX2 mentioned) PHP can't call a JavaScript function.

PHP is server-side, whereas JavaScript is client-side. Since the code is running on separate machines, there's no way for them to directly communicate.

Now, you can have the PHP output JavaScript that you'd like the browser to run while it's loading the page, and you can use AJAX to send a new HTTP request to the server to run additional scripts after the main page has loaded, but those are your best options.

[evicailieva]

I mean it does not execute the code in the function showListTurist(), it doesn't open new window.

[pbmods]

Heya, Evicailieva.

You mean that when you click on the links in the table cells, it's not opening the new window, correct?

Are you getting an error, or is it just not doing anything?

[evicailieva]

Yes that's exactly what I mean. It does not show errors. It does nothing. I really don't know what's wrong! I also have this code

[PHP]echo <<<END
<tr>
<td colspan=3 align="right">
Òóðèñò:
<input type="text" name="turistid" size="34" value="òóðèñò">
<input type="button" value="èçëèñòà¼" onClick="showListTurInsert()" class="button">
</td>
</tr>
END;[/PHP]

and also dosen't open new window. It also does nothing.

There is one more thing I think may be causing a problem.

You call a JavaScript function through the onclick event in a <a> tag, but it the same tag you set the href parameter, trying to pass the url in the href parameter to the window, opened by you JavaScript function.
This will not work. What actually happens is, when your user clicks the <a> link, the JavaScript function is executed, and then the client is redirected to the URL in the href parameter

For example:

<script type="text/javascript">
function alertme() 
{
    alert("You have been alerted!");
}
</script>
 
<a href="?var=val" onclick="alertme();">Linkage</a>
 

This will put up an alert box and then it will redirect you to '?var=val'.

You would need to do something like this:

<script type="text/javascript">
function openWindow(getParams) 
{
    window.open("mypage.php?"+ getParams);
}
</script>
 
<a href="#" onclick="openWindow('var=val');">Linkage</a>
 

Which will open up another window showing the page 'mypage.php?var=val'.

[evicailieva]

Thank you very much. That works.
