Sorting Tags Alphabetically

[tahirk]

I'm having a tags group from where we can select different number of tags. Currently, these tags are being displayed in order in which they are input. I want these to be displayed in an alphabetical order.

 

Here is the php code for the part (ta_name is what I want this to sort to):

<div class="control-group">
    <label class="control-label" for="qu_tags[]"><?php echo lang("input_tags"); ?></label>
    <div class="controls">                            
        <select id="qu_tags" name="qu_tags[]" size="10" multiple="multiple">
            <option value="">- Choose Tags</option>                        
            <?php foreach ($tags as $ta) { ?>
                <option value="<?php echo $ta["_taid"]; ?>" <?php echo set_select('qu_tags[]', $ta["_taid"]); ?>><?php echo $ta["ta_name"]; ?></option>
            <?php } ?>                                              
        </select>
        <span class="help-inline error"><?php echo form_error("qu_tags[]"); ?></span>     
    </div>
</div>

Can you please help me in here to display them in an alphabetical order regardless of the way they are input.

It is too late to sort $tags at that point. You need to sort it earlier: either in the database query you used, or with something else.

 

Where is $tags defined and where are the values coming from?
