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?

by TPL files do you mean Smarty? How is the $foot getting into the tpl file? — Tom Haigh

Maybe telling people that you use a template engine instead of letting them guess would have been a nice thing to do. — Tomalak

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}";

not working, I also noticed that the last quotation mark in your solution is a double, fixed that, still not working

Tomalak Over a year ago

Yes. Seen that too late, fixed.

-1 because this is simply not true echo "{1+1}"; will not output "2". The {} within double quotes is only used for disambiguating variables, e.g. "he drank some {$beer}s." The issue here is most likely the templating engine, in which case a fix would depend on which engine was in use.

Tom Haigh Over a year ago

This isn't correct - the $foot = "<script... etc. line evaluates correctly

Tomalak Over a year ago

That there was a template engine involved was not clear to me. Should have thought of that though.

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.

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.

-1 because php doesn't parse {var} as a variable. It uses $var, ${var}, or {$var}

donohoe Over a year ago

I didn't say {var} ... ? All I said is that it expects a variable; in which case yes it would be along the lines of {$var}

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

literal
