parsing html <script> via PHP isn't working completely.

Question

I find this very strange, must be something I'm doing wrong, but still... I'm working on a page using PHP and TPL files. In my TPL file, there's a place in the footer for some extra lines if needed.

For instance, formchecking with Javascript.

so in PHP I did this:

$foot = "<script type=\"text/javascript\">if(document.getElementById){loadEvents();}</script>";

the $foot variable is then parsed and the result in HTML is this:

<script type="text/javascript">if(document.getElementById)</script>

So {loadEvents();} went missing.

Does anybody see what I'm missing here... I'm seriously not finding it. Did I forget to escape a character or something?

Answer 1

I believe with {} that PHP is expecting a variable within them. I haven't tested this, but try using single quote instead of double-quotes.

Answer 2

Obviously the template engine you are using eats away the part in curly braces.

Try something like:

$foot = "{literal}<script type=\"text/javascript\">if(document.getElementById){loadEvents();}</script>{/literal}";

Answer 3

It looks like you're using a template engine like Smarty, which tries to parse anything it finds within braces.

This page from the smarty documentation explains how to make smarty ignore sections it would otherwise parse.

Answer 4

If you are using smarty you could use the {literal}.
