cmCalendar Module "event owned by user" enhancement

Post by thoblerone » Mon 1. Nov 2010, 19:43

Hello everyone,

thanks "breitsch" for a really great cmCalendar mod and that he already put the neccessary table fields into the DB! Today I finished pushing the module a step forward by adding some backend user security features:

a) Only users from the Admin group may create, edit or delete cmCalender categories
b) Any events is assigned an owner (creator). Only the owner and users from the admin group may edit or delete a given cmCalendar event

Using this modification it is possible to have various standard backend users sharing the same calendar but they are not able to change each others entries.

Required changes are only a few and pretty easy. Important notice: line numbers specified are referring to the unchanged files, even if after the first changes you may have added a few lines! Anyhow most of the times I specified the old lines which are quite unique around their place.

a) Event categories only for admins just needs two changes in mod_cm_calendar\inc\listing.cal.inc.php

line 115ff change this

Code: Select all

<div class="navBarLeft imgButton chatlist" style="float:left">
	&nbsp;&nbsp;
	<a href="<?php echo cm_map_url('controller=cal') ?>&edit=0" title="<?php echo $BLM['create_new_cal'] ?>"><img src="<?php echo $phpwcms['modules'][$module]['dir'].'img/'; ?>cal_add.gif" alt="Add" border="0" /><span><?php echo $BLM['create_new_cal'] ?></span></a>
</div>
to (must be admin to add category)

Code: Select all

<?php // TB Modification: only admins may create calendar categories
	if ($_SESSION["wcs_user_admin"] == 1) {
		echo '<div class="navBarLeft imgButton chatlist" style="float:left">'.LF;
		echo '&nbsp;&nbsp;'.LF;
		echo '<a href="' . cm_map_url('controller=cal') .'&edit=0" title="'. $BLM['create_new_cal'] .'">';
		echo '<img src="'. $phpwcms['modules'][$module]['dir'].'img/' . 'cal_add.gif" alt="Add" border="0" />';
		echo '<span>' . $BLM['create_new_cal'] .'</span></a>'.LF;
		echo '</div>'.LF;
	}
?>
line 203 (as in the unchanged file!!!) insert (only admins my change or delete categories)
old line 203:

Code: Select all

echo '<a href="'.$controller_link.'&edit='.$row["cm_cat_id"].'">';
new lines 203/204:

Code: Select all

	if ($_SESSION["wcs_user_admin"] == 1) {
		echo '<a href="'.$controller_link.'&edit='.$row["cm_cat_id"].'">';	
after line 213 add

Code: Select all

	   // }  <-- this is the old line 213: commented out bracket 
	}
	else
	{
		echo '&nbsp;';
	}
Thats all for the category thing.

b) Some more work is needed for event user management.

mod_cm_calendar\lang\de.lang.php
add this line, best fitting at line 69

Code: Select all

$BLM['entry_uid']             = 'Termin Besitzer';

Thats it with the required changes in the backend. But I found that changing two templates adds further comfort in the frontend.

mod_cm_calendar\template\print\frontend_listing_print.tmpl (complete code here. Picture formatting was changed to keep aspect)

mod_cm_calendar\template\cntpart\ tb_event_listing.tmpl Enhanced template for the event listing. Calender entries are completely depending on css entries which (can) eliminates some fixed div positioning which lead to ugly overlapping displays, e.g. at event day and day details.

I have included some minor but recommended changes in the event edit form (around mod_cm_calendar\inc\edit.events.inc.php line191 ff) into the original posting.
