Vote Compress Forum Templates for HOTM

Description:

Hi, this is a pretty simple hack that involves compressing the 'compiled' version of your templates, this way it only compresses the part thats to be shown on the forum and not the actual template data you edit.

Background:

Got the idea from Zero Tolerance in buro9's thread:
https://vborg.vbsupport.ru/showthread.php?t=69787

The above hack compresses the page at parse time, while it provides some speed enhancement, on large pages you can actually "negate" the point of using the hack in the first place, because of the overhead in compression.

Thus, the creation of this hack is to provide similiar functionality, but done in the adminCP; and without the overhead of constant compression.

Info:

No Queries. Only query is used when compressing your templates, the rest of the time its just pulling the templates straight out of the database like normal.

Updates:

Version 2.8 - Added Strip Whitespace from Start of JS Line by buro9
Version 2.7 - Option to strip HTML Comments from Compressed Output
Version 2.6 - Removed Phrase Compression altogether, Too Iffy
Version 2.5 - Removed the ASCII \n removal, emails should work now.
Version 2.4 - Had to add editor_jsoptions_size to the Bad Templates array, it also was causing a font selection error.
Version 2.3 - Added Phrase compression support, should help further increase page compression.
Version 2.2 - Slightly Recoded Template compression for faster results.
Version 2.1 - Added php_include templates to bad templates, will not compress these.
Version 2.0 - Recoded Script, added support for certain templates to not compress
Version 1.9 - Re-Added support for InLine Styles.
Version 1.8 - Removed support for InLine Styles, all Style data is left with Linebreaks.
Version 1.7 - Removed support for InLine Javascript, all JavaScript is left with Linebreaks.
Version 1.6 - Fixed Tab problem, tabs are replaced with a single space
Version 1.5 - Removed a part of the SQL.
Version 1.4 - TOTALLY Remade, Works perfect now; Ultimate Compression
Version 1.3 - Adjusted Again
Version 1.2 - Adjusted Stripping regex
Version 1.1 - Added Uncompress Support
Version 1.0 - Release

Install:

Step 1. [ Open admincp/template.php ]
Step 2. [ Go to about line: 1278, or just look for $_REQUEST['do'] == 'edit' ]
Step 3. [ Above Step 2, add the below code ]

Step 4. [ close admincp/template.php and open admincp/index.php ]
Step 5. [ look for ]

PHP Code:

construct_nav_option($vbphrase['find_updated_templates'], 'template.php?do=findupdates', '<br />'); 


Step 6. [ below this, add the code ]

PHP Code:

construct_nav_option("Compress Templates", 'template.php?do=compressall', '<br />');
construct_nav_option("Uncompress Templates", 'template.php?do=compressall&revert=1', '<br />'); 


How-To Run

1. Install
2. In the admincp left navigation, select "Compress Templates".
3. Repeat Step 2 after each modification of your Templates whenever you decide to change something.
4. If you want to uncompress all Templates, select "Uncompress Templates"
5. IF Any Templates Come Out Weird, add the template Name to the Bad Templates Array and Re-Run the Compress Templates.

Update;

Contact with Blamz, fixed problem.

Notice;

Everyone, even if you have installed this hack. REINSTALL it with the latest code, it drastically changes some stuff that would cause errors otherwise..

[jcr]

New version installed, just one quickie before I do anything;

Should I uncompress before applying the new way to compress?

Edit:

One more thing, the reputation images gets very seperated after this hack :-/

Nah, everytime you select compression, its source is from the "editable" version of the templates.

In other words, everytime you select Compress Templates its compressing them freshly.

Mine does'nt :/

Try uncompress/compress, if that doesn't work, paste the html code of posts where this is affected, if I see what the html looks like I may can help you.

Almost post a screenshot.

Works aok for me, not sure if I see much of a difference performance wise

It has more of a bandwidth save than performance

If you use this in addition to gzip compression you will save roughly 50-60% in total bandwidth per page.

Okay hm, I have removed the reputation in the postbit, it is in the memberlist, things looks kinda strange over at my place.

Uncompressing, and then compressing again removed the whitespace between the reputation images

[The Realist]

This latest code does not work for me in IE, the one before worked ok. What Im getting now is my dropdown menues work ok but when I click the New Posts link nothing happens?

Owe well.
