Assign variable in smarty?

I have assigned two array to smarty : profiles and selected_id . profiles array contains the array of all profiles and the selected_id array c开发者_Go百科ontains ids of the profiles to be displayed .So I am displaying the all profiles like this :

<select id="countries" class="multiselect" multiple="multiple" name="profiles[]">
        {foreach name = feach item = k from = $profiles}
            <option value="{$k->bz_pro_id}">{$k->bz_pro_first_name} {$k->bz_pro_last_name}</option>
        {/foreach}
      </select>

Now I want to default select the ids that are already selected by admin . That means if I want to add selected = "selected" in the option of select . For that I write :

{foreach name = feach item = k from = $profiles}
        {foreach name = feach2 item = k2 from = $selected_id}
                {if $k->bz_pro_id == $k2->bz_pro_id}
                        selected = "selected"
                {/if}
        {/foreach}
{/foreach}

So can I assign the select = "selected" to a variable so that I can use it in the option ?

I have tested this, and it works. Assuming your arrays look something like this:

$profiles[] = array ( 'bz_pro_id' => '1', 'bz_pro_first_name' => 'test1', 'bz_pro_last_name' => 'test2');
$profiles[] = array ( 'bz_pro_id' => '2', 'bz_pro_first_name' => 'test3', 'bz_pro_last_name' => 'test4');
$selected_id = array('1');

The syntax you're using to access variables and array members isn't correct. This is the working solution:

<select id="countries" class="multiselect" multiple="multiple" name="profiles[]">
    {foreach name=feach item=k from=$profiles}
        <option value="{$k.bz_pro_id}" 
           {if in_array($k.bz_pro_id, $selected_id)}selected{/if}>
            {$k.bz_pro_first_name} {$k.bz_pro_last_name}
        </option>
    {/foreach}
  </select>

you can use following code.

<select id="countries" class="multiselect" multiple="multiple" name="profiles[]">
        {foreach name = feach item = k from = $profiles}
            <option value="{$k->bz_pro_id}" {if $k->bz_pro_id|in_array($selected_id)}selected = "selected"{/if}  >{$k->bz_pro_first_name} {$k->bz_pro_last_name}</option>
        {/foreach}
</select>
