Using php with javascript

[bird_man11]

Hey guys i new to this forum and are having some trouble with double combo boxes, i have a javascript script that allows me to do this fine but the data i want to be put in the second combo box is stored into a database. this is my code at the moment. the while loop in the php seems to be the problem

 

This is the original javascript:

 

<form name="doublecombo">
<p><select name="example" size="1" onChange="redirect(this.options.selectedIndex)">
<option>Technology Sites</option>
<option>News Sites</option>
<option>Search Engines</option>
</select>
<select name="stage2" size="1">
<option value="http://javascriptkit.com">JavaScript Kit</option>
<option value="http://www.news.com">News.com</option>
<option value="http://www.wired.com">Wired News</option>
</select>
<input type="button" name="test" value="Go!"
onClick="go()">
</p>

<script>

var groups=document.doublecombo.example.options.length
var group=new Array(groups)
for (i=0; i<groups; i++)
group[i]=new Array()

group[0][0]=new Option("JavaScript Kit","http://javascriptkit.com")
group[0][1]=new Option("News.com","http://www.news.com")
group[0][2]=new Option("Wired News","http://www.wired.com")

group[1][0]=new Option("CNN","http://www.cnn.com")
group[1][1]=new Option("ABC News","http://www.abcnews.com")

group[2][0]=new Option("Hotbot","http://www.hotbot.com")
group[2][1]=new Option("Infoseek","http://www.infoseek.com")
group[2][2]=new Option("Excite","http://www.excite.com")
group[2][3]=new Option("Lycos","http://www.lycos.com")

var temp=document.doublecombo.stage2

function redirect(x){
for (m=temp.options.length-1;m>0;m--)
temp.options[m]=null
for (i=0;i<group[x].length;i++){
temp.options[i]=new Option(group[x][i].text,group[x][i].value)
}
temp.options[0].selected=true
}

function go(){
location=temp.options[temp.selectedIndex].value
}
//-->
</script>

</form>

And this is the altered one i have done:

 

<script>

var groups=document.doublecombo.example.options.length
var group=new Array(groups)
for (i=0; i<groups; i++)
group[i]=new Array()
<?php
$i = 0;
$lensdesignq = mysql_query("select LensDesign from lenstypes group by lensdesign");
while ($option2 = mysql_fetch_array($lensdesignq, MYSQL_ASSOC)){
$lenstype = $option2['LensDesign'];
$lenstypeq = mysql_query("select LensType from lenstypes WHERE lensdesign = '". $lenstype . "' group by lenstype");
$j = 0;
while ($option3 = mysql_fetch_array($lenstypeq, MYSQL_ASSOC)){ ?>
group[<?php echo '"'.$i.'"';?>][<?php echo '"'.$j.'"';?>]=new Option("<?php echo '"'.$option3["LensType"].'"';?>")
<?php
$j = $j + 1; 
}
$i = $i + 1;
}
?>


var temp=document.doublecombo.stage2

function redirect(x){
for (m=temp.options.length-1;m>0;m--)
temp.options[m]=null
for (i=0;i<group[x].length;i++){
temp.options[i]=new Option(group[x][i].text)
}
temp.options[0].selected=true
}
//-->
</script>

 

any help would be great guys

your php code executes server side and should only be outputting valid javascript code because of its position in the code.  I assume you meant to do that because it looks like you were trying to that.  The php probably just returns invalid js.  Just look at the js in the html source code returned to the browser and you probably will see a simple syntax error in the js produced which you can then trace back to the php code.
