Hi All, i've been feeling a bit festive recently, and have been trying to find a way to embed this javascript in to a mambo PHP page, i've found this script:
<?php
echo "<script language='javascript'>
JAVASCRIPT GOES HERE
</script>
but when i put my javascript in between the tags and i get error message
"Parse error: syntax error, unexpected T_VAR, expecting ',' or ';' in /home/*****/public_html/********.com/web/offline.php on line 39"

any ideas?
:banghead:

putting snow on a website can't be this hard!!!

If there is apostrophe in your javascript you will get error. It must be escaped.

maybe not escaping or anything like that. just do this.

Code: Select all

 
<?php
// code
?>
<script language="javascript">
JAVASCRIPT GOES HERE
</script>
<?php
//more code
?>
 
no need for escaping or any such nonsense. I always use something similar when I'm going to just echo lines directly out, not put them in a variable, and it is multiple lines of html or whatever.

Just barely tested it. The script the give you is wrong. It will not work. Best I can guess they screwed up with line breaks or something. I didn't know enough about javascript to find out what is wrong with it, so I just checked the source of the page. Here is the working script. I checked.

I guess they just like saving the working stuff only for themselves? :dubious:

Thanks again cavemaneca, i'll try a different javascript with your suggestion (i'm sure i can find a simpler one!)

Well, the code i posted there is the working version they use to display it on their page, so what I posted will work.
