...why does this method not work?

Code:

<head> = str_replace('head', 'head class="test"', <head>);

Because "<head>" is not a string variable. :)

hmmm, im no good with preg replaces, but shouldn't something like this work, on either global or parse templates.

this is not working

Code:

$find = preg_replace("/<head[^>]>/i", "TEST", $find);

You don't need to use regex here with preg_replace(), but what you need is to have the template code stored as a string, and then just use str_replace() on the string.

What exactly are you trying to do because the head tag does not take any attributes, so there's literally nothing you can change with the actual tag itself. The contents can be changed but as I said that's easily accomplished with template hooks.

im trying to do something along the lines of (again not the code I'm actually using)

HTML Code:

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:og="http://ogp.me/ns#" xmlns:fb="http://www.facebook.com/2008/fbml">

I was just using the head tag as filler, everything I'm trying to accomplish is the same concept and would be achieved the same way regardless.

so in the end i can replace a tag across multiple templates.

so think of it this way since instead of head, everything on here says body.

i want to add an onload event to all body tags, in every template, without having to say every template.

so we do something like this for every template there is a body tag:

Code:

$find = '<body>';

$replace = '<body onload="myFunction()">';

$vbulletin->templatecache['FORUMHOME'] = str_replace($find,$replace,$vbulletin->templatecache['FORUMHOME']);

$vbulletin->templatecache['showthread'] = str_replace($find,$replace,$vbulletin->templatecache['showthread']);

etc...

i'm simply asking is there a way to do this globally so you dont have to specify every template.

this would be an example of it, but this doesnt work:

Code:

$find = '<body>';

$replace = '<body onload="myFunction()">';

$find = str_replace($find, $replace, $find);

What I would do to add an onload event to the body element on all pages is in a plugin hooked to "parse_templates" with the following:

PHP Code:


		
			
$spacer_close .= '<script>
function myFunction()
{
    alert("Hello!");
}
var el = document.getElementsByTagName("html")[0];
el.innerHTML = el.innerHTML.replace("<body>", "<body onload=\"myFunction();\">");
</script>';

However, there are better ways to add an event to a document, I am just trying to follow the example you gave. :)

mark thanks for always being around to help, but I feel like I'm wasting your time =/

I was only throwing another example to what could be achieved with the end result I'm looking for.

so lets look at what I'm intending on doing:
In every template that has a <html> tag, i want to add some attributes.

so lets say for just a one attribute example this is exactly what i want to do.

across every single template:

Code:

$find = '<html>';

$replace = '<html lang="en">';

$find = str_replace($find, $replace, $find);

we've already established that wont work,
but the end result should be something like this if it's achievable.

instead of doing:

Code:

$find = '<html>';

$replace = '<html lang="en">';

$vbulletin->templatecache['Template1'] = str_replace($find,$replace,$vbulletin->templatecache['Template1']);

$vbulletin->templatecache['Template2'] = str_replace($find,$replace,$vbulletin->templatecache['Template2']);

$vbulletin->templatecache['Template3'] = str_replace($find,$replace,$vbulletin->templatecache['Template3']);

$vbulletin->templatecache['Template4'] = str_replace($find,$replace,$vbulletin->templatecache['Template4']);

$vbulletin->templatecache['Template5'] = str_replace($find,$replace,$vbulletin->templatecache['Template5']);

$vbulletin->templatecache['Template6'] = str_replace($find,$replace,$vbulletin->templatecache['Template6']);

$vbulletin->templatecache['Template7'] = str_replace($find,$replace,$vbulletin->templatecache['Template7']);

etc....

This works on my vB 4.2.x dev site...a plugin hooked at "parse_templates":

PHP Code:


		
			
$t_arr = $vbulletin->templatecache;
$t_keys = array_keys($t_arr);
$count = count($t_keys);

for ($n = 0; $n < $count; $n++)
{
    if (strpos($t_arr[$t_keys[$n]], '<body') !== false)
    {
        $vbulletin->templatecache[$t_keys[$n]] = str_replace('<body', '<body name="myName"', $vbulletin->templatecache[$t_keys[$n]]);
    }
}

Yeah, I got the same on my vB 3.8.9 dev site, but I thought it worth a shot since it works with vB 4.2.x. :)

--------------- Added [DATE]1460691040[/DATE] at [TIME]1460691040[/TIME] ---------------

This works on my vB 3.8.9:

PHP Code:


		
			
$t_arr = $vbulletin->templatecache;
$t_keys = array_keys($t_arr);
$count = count($t_keys);

for ($n = 0; $n < $count; $n++)
{
    if (strpos($t_arr[$t_keys[$n]], '<body') !== false)
    {
        $vbulletin->templatecache[$t_keys[$n]] = str_replace("<body", "<body name='myName'", $vbulletin->templatecache[$t_keys[$n]]);
    }
}
