How to pass javascript variable to php on javascript generated page?

[Arsale]

I am trying to pass a javascript variable to php on javascript generated page, but on the new page I got only "Array". Where did I go wrong?
On first page, i've got image map with areas. Onmouseover javascript read area names and send it to javascript generated page. On generated page, area name (from first page) need to be query variable (depending of them show data from database). If i put string instead of variable,everything works fine, result is ok. Only problem is (i think) get variable from html to php on same page.

<script>
new_window.document.write("<title>".concat(x,"</title>","<?PHP
    $rst = mysql_connect("127.0.0.1","root","12345");
    $a =$_SERVER['PHP_SELF'];
    preg_match_all('/<title>(.*?)<\/title>/',$a, $match);
    $script = $match[0];  
    echo $script;
    echo "<br />";
 
    if (!$rst){
    echo( "<p>Unable to connect to database manager.</p>");
        die('Could not connect: ' . mysql_error());
    }
    mysql_select_db("oprema", $rst);
 
    $result = mysql_query("SELECT * FROM oprema WHERE mreznomesto='$script'");
 
    while($row = mysql_fetch_array($result)) {
        print( $row['mreznomesto'] . " " . $row['serijskibroj']);
        echo "<br />";
    }
?>"));
</script>

Try print_r instead of echo then you will see the reason

[Arsale]

No, definitely is problem with area definition. When i try print_r instead of echo, got "Unterminated string konstant" error on first page, not open javascript generated page. Same thing is if i replace preg_match_all with preg_match and wrote $script = $match;
Thanks for advice.

I'm unclear on why you're running a preg_match on <title> on the name of the currently executing script. The match array will always be empty as far as I can tell.

What are you actually trying to accomplish?

[Arsale]

Is not necessary to run a preg_mach on <title>, i only need to pass javascript variable from one page to php on another. Second page is popup, which is activated on mouseover imagemap area from first page. If you got same other solution any help is appreciated...

Hi,

Are you trying to do this with AJAX? If so you can pass a variable on the end of the URL you call with the HTTPRequest method. This will then be available in the $_GET array.

I have developed something similar previously using an image map and AJAX. the image map code looked like:

<area shape="poly" alt="Burkina Faso" coords="281,158,275,165,275,166,276,167,278,164,285,164" href="javascript:void(0);" title="Burkina Faso" onclick="mapNavigator(1);">
 

The JS functions:

function GetXmlHttpObject()
 
{ 
 
    if (window.XMLHttpRequest)
 
    {
 
        loXMLHTTP=new XMLHttpRequest() ;
 
    }
 
    else if (window.ActiveXObject)
 
    {
 
        loXMLHTTP=new ActiveXObject("Microsoft.XMLHTTP") ;
 
    }     
 
    if (loXMLHTTP==null)
 
    {
 
        alert ("Browser does not support HTTP Request")    ;
 
         return    ;
 
    }
 
    return loXMLHTTP ;
 
} 
 
 
 
function submitXMLHTTP(poXMLHTTP, pcIDToWriteTo, pcOpenMethod, pcURL, plOpen, pcSendData)
 
{                                                                                        
 
    poXMLHTTP.onreadystatechange = function() 
 
    { 
 
        // use of ghost function enables the system to execute each item in the correct order 
 
        writeResponse(poXMLHTTP, pcIDToWriteTo); 
 
    };
 
    poXMLHTTP.open(pcOpenMethod,pcURL,plOpen) ;
 
    poXMLHTTP.send(pcSendData) ; 
 
} 
 
 
 
function writeResponse(poXMLHTTP, pcEmelentID) 
 
{        
 
    if (poXMLHTTP.readyState==4 || poXMLHTTP.readyState=="complete")
 
    { 
 
        if (poXMLHTTP.status == 200)
 
        {
 
            document.getElementById(pcEmelentID).innerHTML=poXMLHTTP.responseText ;  
 
        }
 
    } 
 
} 
 
 

This worked a treat for me.

I hope this helps you out.

Thanks for advice, i'll try this evening and notify you what i've done.

I solved my problem on very light way. In brackets on javascript function "open_new_window(0)" is index number of map area(very important), and first index is always 0.
Image code is something like:

<map id="imagename" name="imagename">
<area shape="rect" alt="areaname" coords="345,17,391,37" nohref title="areaname" onMouseOver="open_new_window(0)" onMouseOut="close_window()"/>

Javascript is like:

<script type="text/javascript">
function open_new_window(t) {
    var y = document.getElementById("imagename");
    var x=y.getElementsByTagName("area")[t].title;
var url="http://site/phpfile.php?x="
new_window = open(url+x,"","width=450,height=150,toolbar=no,location=no,directories=no,status=no,menubar=no, scrollbars=no,resizable=yes,copyhistory=no");
new_window.document.close(t); }
function close_window() {
new_window.close();
}
</script>

PHP file code is simple:

<?php
     $rst = mysql_connect("loaclhost","root","12345");
       if (!$rst){
     echo( "<p>Unable to connect to database manager.</p>");
       die('Could not connect: ' . mysql_error());
       }
    mysql_select_db("databasename", $rst);
   $title=$_GET[x];
     $result = mysql_query("SELECT * FROM table WHERE `field name1`='".$title."'");
    while($row = mysql_fetch_array($result))
    {
    print( $row['field name2'] . " ||  " . $row['field name3'] . " ||   " .$row['field name4']  . " ||  " .$row['field name5'] );
    echo "<br />";
    }
?>

Thanks for help, i hope to this is useful to someone except me.
