How to enable PHP block in the Page Builder

This is based on an earlier post (and great finding) from jtadeo

http://www.boonex.com/unity/blog/entry/How_to_Add_PHP_in_a_BLOCK

This small 4-steps guide allows you to enable PHP blocks in the Page Builders interface, allowing you to, well, insert PHP inside your pages, as simple as that!

Note: I strongly recommend you backup your BxDolPageViewAdmin.php just in case...

--------------------
STEP 1
--------------------
Run the following Insert query in the pageCompose table:

INSERT INTO `PageCompose` ( `ID` , `Page` , `PageWidth` , `Desc` , `Caption` , `Column` , `Order` , `Func` , `Content` , `DesignBox` , `ColWidth` , `Visible` , `MinWidth` )
VALUES (NULL , '', '960px', 'PHP Block', '_PHP Block', '0', '0', 'Sample', 'PHP', '1', '0', 'non,memb', '0');

The key field is "Func", being set to "Sample". Any record set to "Sample" in this table will make the relevant block appear among the Samples(!) in the "page builders" section. Try and look at any page from the Page Builders screen, you'll now see the PHP block displayed as Sample.

--------------------
STEP 2
--------------------

Edit the following file:
./inc/classes/BxDolPageViewAdmin.php

Update the saveItem function (starting line 174) by modifying line 187:

FROM: elseif( $sFunc == 'Echo' )
TO: elseif( $sFunc == 'Echo' or $sFunc == 'PHP' )

This will enable the PHP code to be saved from the admin interface.

--------------------
STEP 3
--------------------

Modify line 553:

FROM: if( $aItem['Func'] == 'RSS' or $aItem['Func'] == 'Echo' ) {
TO: if( $aItem['Func'] == 'RSS' or $aItem['Func'] == 'Echo' or $aItem['Func'] == 'PHP' ) {

This will enable the "Delete" button in the PHP blocks popup form

--------------------
STEP 4
--------------------

Search for :

if( $aItem['Func'] == 'Echo' )

This IF condition defines what fields to display in the block popup form, based on the block type/func. You just need to insert the following on line 533
(just before the end of the IF condition for the HTML blocks):

... etc etc...
<?
// THE INSERT STARTS HERE

} elseif( $aItem['Func'] == 'PHP' ) {
?>
<tr>
<td class="form_label">PHP-code:</td>
<td>&nbsp;</td>
</tr>
<tr>
<td class="form_colspan" colspan="2">
<textarea style="width: 450px; height: 350px;" name="Content"><?= htmlspecialchars_adv( $aItem['Content'] ) ?></textarea>
</td>
</tr>
<?

// THE INSERT FINISHES HERE
} elseif( $aItem['Func'] == 'RSS' ) {
... etc etc...

--------------------
ET VOILA!
--------------------

Now you can manage PHP blocks straight from the admin section without having to fiddle with MySQL or other geeky stuff!

Personally I can think of loads of new blocks I'm gonna create... right now actually!

Dunno what's coming up with 6.2, hope fully they'll incorporate this by default :-)

HAVE FUN!
