Let visitor select which category is displayed in the monthly calendar

Hi,

If you a lot of event in the calendar it gets confusing fast. Is there a possibility to let the visitor select which categories of events is displayed in the monthly calendar view (like a select field)?

Thanks

Sure, just add a category drop-down to your page by inserting the code below:

PHP Code:

<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<=8; $N++) {
   if ($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>

Have modified the code to clean up the html and allow use a dynamic count of categories.

add before form: <?php $count_cat = count($cat); ?>
reason: To allow dynamic count of categories

<form action="<?php echo $PHP_SELF?>" method="post" name="filterForm" id="filterForm">
<span class="smallText">Select Category: </span>
<select name="showCat" class="formElements" id="showCat">
change: <option value="">
to: <option value="">--- Show All ---</option>
reason: Add selection and close option tag
<?php
// CATEGORY OPTIONS
change: for ($N=1; $N<=8; $N++) {
to: for ($N=1; $N<=$count_cat; $N++) {
reason: Substitute actual count for fixed value
if ($cat[$N]!="") echo "<option class=\"s2".$N."\" value=\"$N\"";
if ($showCat==$N) echo " SELECTED";
add: if ($cat[$N]!="") echo ">$cat[$N]</option>\n";
reason: eliminate extra "></option>" lines added for empty categories with original code.
}
?>
</select>
<input name="filterButton" type="submit" class="formButtons" id="filterButton" value="Go">
</form>
