php with javascript

[jacinthe]

mornin' :o)

I have a form with a list box. on change of that box, i want that all my other textfield change according to the value selected in the list. The problem is, i don't know how to put a php variable into a javascript command... here, take a look at my line :

<select name="select" onChange="MM_changeProp('textfield1','','value',$my_value,'INPUT/TEXT')">

i kept getting an error message from javascript...

someone got an idea?

really thanx you in advance

Jacinthe,

You need to put the PHP variable in an echo statement

eg/

<select name="select" onChange="MM_changeProp('textfield1','','value',<? echo $my_value; ?>,'INPUT/TEXT')">

Hope this helps

here my code :

<script language="JavaScript">
function MM_changeProp(objName,x,theProp,theValue) {
var obj = MM_findObj(objName);
if (obj && (theProp.indexOf("style.")==-1 || obj.style)) eval("obj."+theProp+"='"+theValue+"'");
}
</script>

[...]

$test = "hello";
<select name="select" onChange="MM_changeProp('paget','','value',<? echo $test; ?>,'INPUT/TEXT')">

and here my error message :
"hello" is undefined

i'm lost 🙁

I don't think anyone is going to be able to help you unless you show us the full program and error message (including line number).

You are almost there. In Javascript variables aren't prefixed by anything like the $ in PHP, I'm sure you know this but it helps in the explanation. So all you need to do is add '' around your <? ?> section so that you will pass hello as text and not a variable.

$test = "hello";
<select name="select" onChange="MM_changeProp('paget','','value',<b>'</b><? echo $test; ?><b>'</b>,'INPUT/TEXT')">
