Categories fail outside of current month

Version 6.1.0

When selecting a specific category of events, moving to the next month loses the category selection criteria.

Selecting a category while residing in the next month returns the current month.

In other words, I have an event in May, under category "Community".

I am in April. I select the category Community, nothing shows up.

I move to May. I get all events.

I choose the category Community again.

I am returned to April, and no events display in April. (Because there were no Community events in April).

Don'tcha just love this kind of circular spaghetti logic problems?

But I still love the calendar, I really do.

I'm not sure where in the script to select a category as the only place this appears is in the Event Manager.

Is this where you see this occur or are you using your own category filter drop-down on your display page(s)?

Ah, that question is it's own answer. Yes, I did install a Category drop down on my page, so of course it's outside of the script. [img]images/icons/icon10.gif[/img]

I added this code after lifting it out of the events module thinking that wherever the variable containing the current month was for the Calendars << == >> functions, it would carry through to the categorical querying also:

<form action="<?php echo $PHP_SELF?>" method="post" name="filterForm" id="filterForm">
<span class="smallText">Select Category:
</span>
<select name="showCat" class="formElements" id="showCat">
<option value="">
<?php
// CATEGORY OPTIONS
for ($N=1; $N<=50; $N++) {
if ($cat[$N]!="") echo "<option class=\"s2".$N."\" value=\"$N\"";
if ($showCat==$N) echo " SELECTED";
echo ">$cat[$N]</option>";
}
?>
</select>
<input name="filterButton" type="submit" class="formButtons" id="filterButton" value="Go">
</form>

And it almost works! As long as you only want to filter on categories for the current month, it's fine.

Actually, it's easily fixable... add this first piece of code before your drop down (these are PHP statements so should be enclosed in <?php ?> tags).

PHP Code:


			
import_request_variables("GP");

if (!isset($mo)) $mo = date("m");

if (!isset($yr)) $yr = date("Y");

And then add these two fields to your form to retain the values of the displayed month and year (this is plain HTML, so just add it to your form).

HTML Code:

<input type="hidden" name="yr" value="<?php echo $yr;?>">
<input type="hidden" name="mo" value="<?php echo $mo;?>">

Tested and it works (somewhat)... If you click to change month, you will lose which category is selected, but if you change month and then choose the category, you will stay on the month you were and the category will show up (as well as stay selected in the drop down).

Hope this helped.

I believe (i.e. untested) that if you change your category form from post to get method="get" this issue may be corrected? It may be necessary to post the hidden mo and yr variables in this form.

:
Perfect!

Exact code as follows integrating both your suggestions works perfectly.
-----------
<body>

<?php $OL=1; require ("calendar/calendar.php"); ?>

<?
import_request_variables("GP");
if (!isset($mo)) $mo = date("m");
if (!isset($yr)) $yr = date("Y");
?>

<form action="<?php echo $PHP_SELF?>" method="get" name="filterForm" id="filterForm">

<input type="hidden" name="yr" value="<?php echo $yr;?>">
<input type="hidden" name="mo" value="<?php echo $mo;?>">

<span class="smallText">Select Category:
</span>
<select name="showCat" class="formElements" id="showCat">
<option value="">
<?php
// CATEGORY OPTIONS
for ($N=1; $N<=50; $N++) {
if ($cat[$N]!="") echo "<option class=\"s2".$N."\" value=\"$N\"";
if ($showCat==$N) echo " SELECTED";
echo ">$cat[$N]</option>";
}
?>
</select>
<input name="filterButton" type="submit" class="formButtons" id="filterButton" value="Go">
</form>

...etc., etc., etc

</body>

This should almost be a how-to instead of a bug report.
