Helpfiles Mod

[smsulliva]

I am trying to further integrate some data tables into phpbb and need help how to write this helpfile mod. Our old php page worked and here is the code. Can someone help me convert this to use phpBB templates.

Code: Select all

<?php
//check for passed variables
$item = ''; //variable to hold the individual helpfile currently in view
if(isset($_GET['item']))
{
   $item = $_GET['item'];
}

$category = ''; //variable to hold the selected category to be listed
if(isset($_GET['category']))
{
   $category = $_GET['category'];
}

$letter = ''; //variable to hold the selected letter to be listed
if(isset($_GET['letter']))
{
   $letter = $_GET['letter'];
}

$keyword = ''; //variable to hold the entered search criteria to be listed
if(isset($_GET['keyword']))
{
   $keyword = $_GET['keyword'];
}

?>
<div id="content">
<div align="center">

<?php
//if an item has been chosen show the individual helpfile

if($item != '')
{
   //get the details of the selected helpfile
   $helpQry = "SELECT * FROM DB1.helpfiles WHERE name = \"".$item."\"";

Anybody want to give this one a try?

[smsulliva]

I can't believe anybody would be able to give me some suggestions on this.

[RMcGirr83]

you would need to split the echos out into a tpl file and move the functions into includes/functions.php

shouldn't be too bad look at the blank template mod for more ideas.

[smsulliva]

There isn't any functions in this.
I have tried to move that and the .item isn't working even the $category.

Please someone give me an example. Just learning here.

[RMcGirr83]

this is a function

Code: Select all

function parse_string($string_to_parse)
{
   //check the string for #0 and replace them with </b>
   $string_to_parse = str_replace("#0","</b>", $string_to_parse);
   
   //check the string for any #n remaining <b>
   $string_to_parse = str_replace("#1","<b>", $string_to_parse);
   $string_to_parse = str_replace("#2","<b>", $string_to_parse);
   $string_to_parse = str_replace("#3","<b>", $string_to_parse);
   $string_to_parse = str_replace("#4","<b>", $string_to_parse);
   $string_to_parse = str_replace("#5","<b>", $string_to_parse);
   $string_to_parse = str_replace("#6","<b>", $string_to_parse);
   $string_to_parse = str_replace("#7","<b>", $string_to_parse);
   $string_to_parse = str_replace("#8","<b>", $string_to_parse);
   $string_to_parse = str_replace("#9","<b>", $string_to_parse);
   $string_to_parse = str_replace("(null)"," ", $string_to_parse);
   
   //insert line breaks where needed
   $string_to_parse = nl2br($string_to_parse);
   
   //return the parsed string
   return $string_to_parse;
}


[smsulliva]

I moved the function to the includes/functions.php file (I can't believe I didn't see that one)

I looked at the Blank Template Mod again. I used that for a bunch of my other pages, that just have content on them, but no database interaction. The MOD doesn't really give much for examples.

[smsulliva]

Started to convert this to a mod and here is part of what I have. I think I am messing up somewhere.

Code: Select all

<?php

// standard hack prevent
define('IN_PHPBB', true);
$phpbb_root_path = './';
include($phpbb_root_path . 'extension.inc');
include($phpbb_root_path . 'common.'.$phpEx);

//
// Start session management
//
$userdata = session_pagestart($user_ip, PAGE_HELP);
init_userprefs($userdata);
//
// End session management
//

// set page title
$page_title = $lang['Help']; // You'll have to set this in a $lang file somewhere

// standard page header
include($phpbb_root_path . 'includes/page_header.'.$phpEx)

// assign template
$template->set_filenames(array(
        'body' => 'help_body.tpl')
);

//check for passed variables
$item = ''; //variable to hold the individual helpfile currently in view
if(isset($_GET['item']))
{
   $item = $_GET['item'];
}

$category = ''; //variable to hold the selected category to be listed
if(isset($_GET['category']))
{
   $category = $_GET['category'];
}

$letter = ''; //variable to hold the selected letter to be listed
if(isset($_GET['letter']))
{
   $letter = $_GET['letter'];
}

$keyword = ''; //variable to hold the entered search criteria to be listed
if(isset($_GET['keyword']))
{
   $keyword = $_GET['keyword'];
}

if($item != '') {
   $helpQry = "SELECT * FROM DB1.helpfiles WHERE name = \"".$item."\"";
   $helpRes = mysql_query($helpQry) or die(mysql_error());
   $helpArr = mysql_fetch_array($helpRes);
   
   $template->assign_block_vars('switch_item',
      array(  'ITEM' => $item,
            'HELP_ARRAY' => parse_string($helpArr['entry']) )
   );
   
               'RELATED_ENTRIES' => $related_entries_array = explode(" ", $helpArr['related_entries']),

for($i=0;$i<count($related_entries_array);$i++)
         {
     $template->assign_block_vars('my_loop',array( 'THIS_LOOP' => <a href='index.php?location=help&item=".$related_entries_array[$i]."'>".parse_string(
                         $related_entries_array[$i])."</a>),
                                                   'TOTAL_LOOPS' => $n
                                                 )
                                   );               
               
         }


} //END IF


** MORE GOES HERE **




$template->pparse('body');

// standard page footer
include($phpbb_root_path . 'includes/page_tail.'.$phpEx);

?>



Beginning tpl file

Code: Select all

<html>
<!-- BEGIN switch_item -->
<h3>{ITEM}</h3>

   echo("<tr><th align='left'>".$item."</th></tr>");
   echo("<tr><td align='left'>".parse_string($helpArr['entry'])."</td></tr>");
   echo("<tr><th align='left'>Related entries:");


<table>
<tr>
   <td class="row1">{ITEM}</td>
</tr>
  <tr>
   <td class="row1">{HELP_ARRAY}</td>
</tr>
    <!-- BEGIN my_loop -->
<tr>
   <th>Related entries:  {RELATED_ENTRIES}</th>
   <!-- END my_loop -->
</tr>
</table>
  <!-- END switch_item -->


Does that look right so far.

[Brf]

The items in "switch_item" will need to be qualified like this:

Code: Select all

{switch_item.ITEM}
{switch_item.HELP_ARRAY}

You are defining 'RELATED_ENTRIES' as a regular scaler, but you includes it two deep in loops in your template....

since 'my_loop' is within another switch, it will have to be defined as:

Code: Select all

$template->assign_block_vars('switch_item.my_loop'

and you would have to define:

Code: Select all

{switch_item.my_loop.THIS_LOOP}
{switch_item.my_loop.TOTAL_LOOPS}

within it, in the template

[smsulliva]

You are defining 'RELATED_ENTRIES' as a regular scaler, but you includes it two deep in loops in your template....

since 'my_loop' is within another switch, it will have to be defined as:

Where do I put my RELATED_ENTRIES in my function


Thanks for the input. Does it look like that what I am doing is going to work from the above real code area?

Can you tell me how you would suggest doing the <href> link in the loop?

I will try what you suggested. I am hoping I am on the right track.

[Brf]

You need to get rid of this line:

Code: Select all

              'RELATED_ENTRIES' => $related_entries_array = explode(" ", $helpArr['related_entries']),

It is hanging out there by itself, not even in a function.

You need to put these:

Code: Select all

{switch_item.my_loop.THIS_LOOP}
{switch_item.my_loop.TOTAL_LOOPS}

In your template instead of RELATED_ITEMS, since that is what your php is trying to fill.

[smsulliva]

Well here is what I got. Can someone look it over.
I haven't tried it yet, but I thought another set of eyes might be nice.

I am getting this error: Any help

Code: Select all

Parse error: parse error, unexpected '}' in /home/staff13/public_html/forums/includes/template.php(127) : eval()'d code on line 51

Also, I think the URL's aren't going to work. I thought $server_url was a global variable...
Can someone help me on this?
